It’s just good vibes in here. The Role Chemistry Has Played In The 2019 Seahawks’ Success – Seahawks.com

Posted on by

K.J. Wright has seen a lot as the Seahawks longest-tenured player, so when the nine-year veteran says theres something special going on when it comes to the chemistry of this team, its worth paying attention.

The closer the team, the better they play together, the better they play for one another, and this team is definitely close, Wright said. Its just good vibes in here.

Wright then paused to turn the tables on the reporters surround him who usually are the ones asking questions.

I dont know if you can feel the energydo yall feel the energy in locker rooms? Wright asked.

After some nods and affirmative answers, Wright continued, The energy is good in here. It feels good, everybodys happy, everybody wants to win, there aint nobody on no B.S., life is good around here, its a good locker room.

There are a lot of very measurable reasons why the Seahawks are 10-2 this season and in first place in he NFC West. Quarterback Russell Wilson is playing at an MVP level, which combined with a strong running game has given the Seahawks one of the most productive offenses in the NFL; the Bobby Wagner and Wright-led defense has made a big turn over the past month, giving the Seahawks a dangerous, ball-hawking defense; and special teams play has been a big difference maker in several games, including last weeks win over Minnesota.

Much more difficult to quantify, but imperative nonetheless if you ask players and coaches, is the team chemistry, which can fluctuate from season to season as players come and go. And this years team, carrying over what started with a young, retooling team in 2018, has found something special. With that closeness comes not just off-field comradery between players, but a belief in what theyre doing together on the field and a desire to do well for each other. That cant be measured on a stat sheet, but its powerful and a real part of this teams success.

This is the team that I think well look back on, there was this deep seeded, longstanding care for each other that comes about in terms of harmony that they really are together, Seahawks coach Pete Carroll said last month. Theyre with us on everything and theyre going along with it. Theyre pliable in a sense. Theyre growing into the belief that they can win football games. Thats really powerful knowing when you get there. Its obvious with all of the close games that weve played. The ability to do that comes from the belief that they have for themselves, what they are capable of doing, what the guys around them are capable of doing. Thats a very strongness in here. Its like, the force is strong in this room. Its pretty cool.

The chemistry this team has is particularly valuable, players say, when the Seahawks go on the road. The Seahawks are 6-0 on away from CenturyLink Field this season, matching the highest road win total in franchise history, and while that has a lot to do with the talent on the field and the coaching staff, theres also some intangibles in play.

Thats why when Wagner was asked about his teams road success, the first thing he said was, I just think it shows how close of a group we are. When we go on the road, everybodys connected, everybodys together, and I think thats what makes us a really good road teamthe connection, the chemistry, especially on the defensive side because when the offense is up its so quiet. Were able to communicate a lot better, were able to talk to one another a lot better. You can only talk to other people if you have a chemistry with them.

MSU faculty member recognized by top chemistry journal – Mississippi State Newsroom

Posted on by

Contact: Sarah Nicholas

STARKVILLE, Miss.A senior member of Mississippi States Department of Chemistry is being recognized as one of the most prolific contributors to an international professional publication.

Dongmao Zhang, an associate professor at the university, recently joined a group of researchers from around the world cited by name in the Journal of Physical Chemistry C. The others work at major institutions of higher learning in China, England, Germany and India.

The journal was created in 2007 to highlight investigations of physical chemistrys sub-disciplines. It is produced weekly by the American Chemical Society, the Washington, D.C.-based organization whose 158,000 members make it the worlds largest scientific body. The ACS also produces physical chemistry journals A and B.

For those not living and breathing chemistry research and education every day, its important to emphasize that the journal is the premier stage and highest impact for scholarship in this essential sub-discipline, emphasized Dennis Smith, head of MSUs Department of Chemistry.

In my view, this is more valuable than many of the more common awards passed around, Smith said, adding that recognition of this sort is focused on a concrete metric of performance and, as such, sounds the alert to the world that we absolutely are competing among the best.

The chemistry department is part of the College of Arts and Sciences, MSUs largest academic unit.

Zhang joined the MSU faculty in 2008 and currently is investigating nanoparticle interfacial interactions, optical spectroscopy and analytical method design. After graduating in 1987 from Chinas Wuhan University, he earned a doctorate in 2002 from Purdue University in Indiana.

Giselle Thibaudeau, the colleges associate dean for research, said the insights and technologies resulting from Zhangs research are critical to understanding and developing nanoscale applications for chemical synthesis, functional nanomaterial design, and ultimately disease diagnosis and treatment.

We are exceptionally proud of Dr. Zhangs accomplishments in this area and of the recognition this brings to MSU, the College of Arts and Sciences and the Department of Chemistry on a national and international scale, Thibaudeau said.

Zhang said the journal recognition truly is a surprising honor to be listed together with researchers from the top universities crossing the world.

It is a manifest that our university and department are competing internationally in fundamental research, Zhang continued. Receiving this distinction would not have happened without the hard work of current and former students in my group, the vital help from our collaborators, and the strong support from the administrators, staff and fellow faculty colleagues in the Department of Chemistry.

For more on Zhang and his research, see http://www.chemistry.msstate.edu/people/faculty/dongmao-zhang.

The College of Arts and Sciences includes more than 5,000 students, 300 full-time faculty members, nine doctoral programs and 25 academic majors offered in 14 departments.

Synchrotron sheds (X-ray) light on carbon chemistry at ocean … – Science Daily

Posted on by

Nature's carbonate system, the dynamic chemistry involving carbon dioxide (CO2), carbonate (CO32-), bicarbonate (HCO3-), and carbonic acid (H2CO3), is a vital component of the biosphere. Carbonate, bicarbonate, and carbonic acid emerge when atmospheric carbon dioxide dissolves in the oceans, which is the largest sink for this greenhouse gas. Researchers are interested in better understanding the carbonate system to potentially help facilitate carbon sequestration schemes, especially with carbon-bonding minerals, to help mitigate climate change. The carbonate system is also central to biological respiration systems, another reason why researchers are interested in this chemistry.

Recently, a group of chemists from the University of California, Berkeley teamed up with scientists at Lawrence Berkeley National Laboratory (LBNL) and made breakthrough discoveries about the carbonate species' behavior at saltwater surfaces, like that of the ocean. They report their findings this week in The Journal of Chemical Physics, from AIP Publishing.

According to one of the paper's authors, UC Berkeley chemistry professor Richard Saykally, a strong motivation for this research was understanding the chemical processes involved in carbon sequestration. They found that while neutral carbonic acid was most heavily present at the surface, as was expected, the more highly charged carbonate ion was more abundant than the weaker bicarbonate.

"We want to generally advance our understanding of the global carbon cycle," Saykally said. "The aspects of this cycle that we have been focusing on begin with carbon dioxide in the atmosphere dissolving into salt water, followed by some very interesting chemistry."

Carbon dioxide is captured by the water surface and hydrated to form carbonic acid or bicarbonate, which can then ionize into either bicarbonate or carbonate where carbonate may react with dissolved magnesium or calcium ions to form limestone.

"We want to know all those steps going from gaseous carbon dioxide in the atmosphere to limestone," Saykally said. "Our goal is to understand all the details in all the steps in that process."

UC Berkeley chemistry doctoral candidate Royce Lam, a co-author of the paper who led much of the research, wanted to build on earlier examinations of the hydration structure of carbonic system species, focusing on the relative abundances of carbonate species at the liquid surface.

Collaborating with LBNL's Dr. Hendrik Bluhm, Lam and co-authors made use of the ambient pressure photoemission spectroscopy (APPES) beamline (11.0.2) at the Advanced Light Source synchrotron at LBNL, to conduct X-ray photoemission spectroscopy (XPS) measurements -- a way to probe the molecular makeup of materials using an intense beam of high-energy X-rays. The XPS system enabled them to probe different aspects of the carbonate system they could not access before.

"What is special about XPS is that it allows us to probe at different depths into the water surface," Lam said. "This is one of the few beamlines in the world that can do this class of experiments on liquids."

For samples, Lam combined solutions of the carbonate species and hydrochloric acid, which fortuitously resembled the ocean system. With a liquid microjet device, the researchers injected these samples into a vacuum chamber and probed them at multiple X-ray energies to deduce the relative abundances of the carbonate species from the photoemitted electrons.

At the liquid surface, both carbonate and carbonic acid were more abundant than biocarbonate. The most significant surprise was that the more highly charged carbonate was more abundant at the surface than the less charged bicarbonate, which conflicts with expectations from existing theoretical models.

This raises important question about where the bicarbonate could be moving in the system, with a possibility that the carbonate could be "ion pairing" with sodium, changing the chemistry, and causing bicarbonate to move to lower depths.

"We are still working on the theory and we hope that this paper will stimulate further theoretical discussion that may actually yield definitive insights about what is going on here," Lam said.

Lam hopes that this research will also lead to more direct research on carbon sequestration possibilities.

"So, the next step would be to look further into ion pairing, and essentially limestone or mineral formation, specifically, looking at the interaction of calcium and magnesium ions with carbonate," Lam said of one carbon sequestration possibility he discussed.

Saykally feels this research connects with the whole system of aqueous carbonate chemistry, with applications ranging from carbon sequestration to biomedical research.

"In order to achieve these kinds of advances, I believe you have to know every detail of the chemistry involved in all those steps of the water-carbonate system." Saykally said. "It is a very intricate chemistry with profound practical implications."

Team USA needs quick spark of chemistry – MLB.com

Posted on by

"I think that a lot of stuff just happens," first baseman Eric Hosmer said of building that chemistry. "A lot of these guys have played against each other through the Minors or with each other when they got to the big leagues. It's not something you can really force the issue on. Hopefully, it'll all just come together when the games start."

The World Baseball Classic runs through March 22. In the U.S., games air live exclusively in English on MLB Network and on an authenticated basis via MLBNetwork.com/watch, while ESPN Deportes and WatchESPN provide the exclusive Spanish-language coverage. MLB.TV Premium subscribers in the U.S. have access to watch every tournament game live on any of the streaming service's 400-plus supported devices. The tournament is being distributed internationally across all forms of television, internet, mobile and radio in territories excluding the U.S., Puerto Rico and Japan. Get tickets for games at Marlins Park, Tokyo Dome, Estadio Charros de Jalisco in Mexico, Petco Park, as well as the Championship Round at Dodger Stadium, while complete coverage -- including schedules, video, stats and gear -- is available at WorldBaseballClassic.com.

Team USA's catchers, Buster Posey of the Giants and Jonathan Lucroy of the Rangers, have the tough task of learning to effectively call games for a staff made up predominantly of short-inning relievers with a varied arsenal of pitches.

"We've had to have a lot of communication. Talking to them in the dugout. Talking to them in the clubhouse so that I can get to know them," Lucroy said. "I know a lot of guys and what they do from facing them. One of the good things about being in the league a decent amount of time is that you know what certain guys want to do against a hitter."

Hosmer and Lucroy are joined by outfielders Adam Jones and Giancarlo Stanton and pitcher Luke Gregerson as the only Classic veterans. All five were members of the 2013 team.

"The will to want to play is a lot from the American players this year, so we are all excited about the chance, and we are going to see what we can do to bring it all home," said Hosmer.

Team USA will face teams that, in some cases, have been practicing as a unit for weeks or more. Most members agreed that the overall talent of this year's squad and the desire to bring the country a Classic title will overcome any unfamiliarity.

"I don't see any weaknesses with this team," said Chris Archer, who will get the start in the opener. "We've got great starters, great relief pitching and great hitters. Everything is a strength with us."

The team didn't exactly show those strengths in a 3-2 loss to the Twins on Wednesday, however. Rockies third baseman Nolan Arenado hit a two-run double in the first inning, but the U.S. was held scoreless by Twins pitchers the rest of the way.

Power of science: Warriors thriving with chemistry experiment

OAKLAND -- Zaza Pachulia holds his own during competitive games of poker on the airplane alongside Stephen Curry and Klay Thompson - they call it the "Good Guys Table." Andre Iguodala and JaVale McGee, one-time teammates with Denver reunited in Oakland, hold secret chats.

"We're building an empire," Iguodala joked. "We've got secret stuff we can't talk about."

Jonnie West - son of Hall of Famer and Warriors executive Jerry West - joins Curry, Pachulia and Thompson for their card games.

"It depends how Klay feels. If he's tired, then no card game," Pachulia said.

With all that was made before the season about adding Kevin Durant to an already star-studded roster, Golden State's players have jelled just fine. The NBA-best Warriors (47-9) are gearing up for the second half and what they hope is another championship run, and chemistry sure isn't holding them back.

Two-time reigning MVP Curry and KD love to watch each other accomplish amazing things on the floor, along with Draymond Green and Thompson and all of the others who contribute off the bench.

Curry initially allowed Durant to find his groove, then began to assert himself more and increase his shots. Experience playing together is the biggest factor to keep building team bonds, if you ask Iguodala.

"Weathering storms builds chemistry and adversity builds chemistry," he said. "The season's long and you want to have all types of ups and downs. And that's where you build it the most, and off the court, plane rides. I think when you play with teammates seven, eight years, you're still building throughout that time. You continue to learn about each other. You've just got to understand that that's part of the process and you've got to want to learn from one another."

The Warriors are counting on every advantage they can gain, on and off the court. During flights, team dinners, anywhere.

After a heartbreaking Game 7 to end last season's NBA Finals, Golden State's players want nothing short of a championship. Many of them got a taste winning the title two years ago for the franchise's first in 40 years.

Steve Kerr, the reigning NBA Coach of the Year, gets a kick out of watching his teams come together each year.

"It's one of my favorite parts of coaching honestly, is seeing how a team comes together, seeing the relationships develop, seeing guys laughing together, seeing who hangs out with who," Kerr said. "It's great. This team has a really, really good chemistry that developed really quickly. Obviously, we had the core group intact from last year. We lost some key guys, too. The additions have been great. The chemistry is really good."

Pachulia took it upon himself to be a part of that. With constant attention on the Warriors, he knows the importance of sticking together through all of the many challenges that come in an 82-game season - and those things prepare a group for the postseason.

"You wish for the chemistry to come right away because you're kind of feeling pressure, a lot of talk's going on from outside," Pachulia said. "The reality is it's a process. It takes some days, it takes some games. It takes some bumps as well for the team to get on the same page and get the chemistry right. You've got to go through the process. I just don't see it the other way. We couldn't wait for these 40 or 50 games to pass and see where we were going to be. I feel really confident where we are right now, with everything we had throughout this 50 games, even the losses we had unexpected. It made us better, it made us stronger. You can appreciate it, honestly. We care about each other. We're on the same page. Keep going. We're not going to stop."

For Iguodala and McGee, the "chatter" stays between them.

"I have a lot of really in-depth conversations with JaVale McGee," Iguodala said, "about life."

OAKLAND -- Mess with one Warrior, you mess with the entire organization.

Thats the message the Warriors sent out Friday in the wake of a Twitter beef between center JaVale McGee and TNT analyst Shaquille ONeal that began late Thursday night and carried into the wee hours Friday morning.

Coach Steve Kerr fired back at ONeal, as did Warriors forward Kevin Durant. The Warriors, as a franchise, contacted ONeals bosses.

Kerr spent a portion of his post-practice news conference Friday afternoon defending McGee from ONeals relentless ridicule on the video segment Shaqtin A Fool. Durant said ONeals ongoing critiques are childish, adding that ONeal was a great player with his own imperfections.

Prior to the comments by Durant and Kerr, though, it was confirmed by CSNBayArea.com that the Warriors contacted Turner Sports in hopes of getting TNTs parent company to persuade ONeal to curb the constant derision directed toward McGee because of its impact on his image and reputation.

The outreach was a direct response to a roughly two-minute segment Thursday night that was strictly limited to castigating McGee.

Upon getting wind of Durants comments, ONeal turned to Twitter to tell Durant that McGee is a bum and to mind yo business.

OAKLAND -- The long-simmering acrimony between retired NBA star Shaquille ONeal and Warriors center JaVale McGee reached epic proportions late Thursday night and early Friday morning when the two engaged in a Twitter beef.

By Friday afternoon, Kevin Durant was stepping into the fray. He didnt bother with Twitter, instead speaking his mind and firing verbal grenades at Shaq.

JaVale works extremely hard, Durant said after practice. He has come in here and done so much for us as a player. He only wants to be respected, just like anybody else. And I understand that Shaq works for a company that wants him to do that type of stuff, and make fun of players. Its cool and funny.

But when you just keep doing it time and time and time again, for no reason, and then a guy actually disagrees with you? And you threaten him? I didnt know cops could threaten civilians like that.

ONeal currently is a reserve police officer in Doral, Fla. He also has served in that capacity in several other cities.

The latest ONeal-McGee spat began when ONeal, now an analyst at TNT who frequently targets McGee for ridicule, presented a video Thursday night that mocked McGee. It was very personal.

McGee took offense and responded on Twitter, which led to the two men exchanging insults, with McGee accusing ONeal of cooning, and ONeal calling McGee dumb and threatening to smack the s--t out of McGee.

Though McGee was not available Friday, he was sharply defended by Warriors coach Steve Kerr and Durant.

Its definitely childish, Durant said. But thats what they want from these stars and these retired players, is to feud with the guys that are playing now and make arguments and disagreements. If I was JaVale, Id feel the same way. Its childish.

Shaq wants to make a joke about it, but if it was him in that position, he would feel the same way.

Everybody cant be Shaq. Hes trying to make his money and enjoy the game of basketball, and his perception of him is that hes a dumb player because he makes mistakes on the court. Shaq was a sh---yfree-throw shooter. He missed dunks. He air-balled free throws. He couldnt shoot outside the paint. He was bigger than everybody. He didnt have any skill. But he was bigger and stronger than everybody.

Durant then turned his head and seemed to speak directly to ONeal.

He was still a great player, but you had your flaws too as a player, he said. And you played on five of six teams, too. So its not like youre this perfect center. You had your flaws too. Like I said, I didnt know cops could go on Twitter and threaten civilians like that. Im glad JaVale challenged him.

Kerr, who has known ONeal for more than 20 years, also came to McGees defense.

I dont blame him for being frustrated, he said Kerr. Shaqs been picki
ng on him for years and years and years. And JaVale, rightfully so, probably gets frustrated. It never ends. And its one thing to just have a little fun, but you can go a little bit over the top.

Its one of those things. If you think about JaVales career, when youre in this position where someone is on national TV making fun of you night after night, its not the greatest thing for your reputation.

I can tell you, I had a preconceived notion of JaVale before he got here that turned out to be totally false. And a lot of that was because of what goes on with Shaqs Shaqtin A Fool thing.

***

Shaq responded to Durant Friday on Twitter, writing "@KDTrey5 mind yo business this ain't for you," and "@KDTrey5 I understand u sticking up for your teammate that's cool but your boy @JaValeMcGee34 is still a bum, he started it I'm a finish it."

Bradley University chemistry demonstration ends with a ‘boom … – Peoria Journal Star

Posted on by

Drew Veskauf of GateHouse Media Illinois

PEKIN As a kindergartner used her weight in an attempt to crush a liquid-filled bottle, her fellow students looked on as it was unscathed.

The lesson, one of many during a Bradley University chemistry demonstration, proved that liquids could not be compressed. The bottles counterpart, however, was filled with air and crumbled when the petite student stepped on it.

For the last part of the school day Friday at L.E. Starke Primary School, students and teachers had a visit from the Bradley University Chemistry Club Demo Crew led by professor Dean Campbell.

Students also saw how liquid nitrogen could freeze a racquetball, making it as fragile as glass, and then saw it shatter after being thrown against a wall.

A simpler demonstration was then held showing that household items such as Alka-Seltzer and water could be combined in a film canister to make miniature rockets. The carbon dioxide gas resulting from the chemical reaction of the two created pressure within the canister, separating it from its lid and blasting it more than 10 feet in the air.

We try and get to educate the community on different aspects of science get them excited about science. Some people use the word edutainment, Campbell said, adding: We dont want it to be scary. We want it to be accessible to people in the safest way as we possibly can.

Campbell, who teaches chemistry and biochemstry, was accompanied by four Bradley students for the visit.

Before the demonstration, students in Marj Oeshs second-grade class were researching and preparing science experiments of their own.

Just as the carbon dioxide and water combination created pressure in the film canisters, Claire Schaefer and Addison Johnson had a similar project of their own answering the question of what happens when a Mentos mint is dropped into soda.

Once the two are combined, there will be an explosion, the girls said.

Our question is how much soda will we have left in the bottle after we add five Mentos, Schaefer said.

We predict the Coca-Cola will have less (liquid) in the bottle, Johnson replied.

Bradley graduate student Dannielle Wentzel said making chemistry less threatening at a young age will hopefully get kids more interested in the field.

I think of what we try to do ... is use things that are accessible for a teacher or a parent, Wentzel said. Personally, I always like to talk about what you encounter on your day-to-day life that is chemistry.

An added bonus for Wentzel, she said, was getting the girls involved in the STEM fields of study.

I want to be out there as much as I can, because seeing that we have three girls doing this demo, its something that they could do, Wentzel said. Even today, I had a girl tell me, I want to be a science person, and she was in kindergarten.

To end the excitement of seeing chemistry in action, the Demo Crew ended it with a boom. A balloon with air was popped, creating a pop heard throughout the gymnasium. The next two balloons, however, were filled with hydrogen gas, and when lit, gave off a louder explosion with a bright yellow flame.

Campbell said the Demo Crew has been doing these community events since 2007 and has done more than 200 of them at various locations in the Peoria area.

Jonathan Toews hoping for time to develop chemistry with linemates … – Chicago Tribune

Posted on by

When the Blackhawks visit the Wild on Wednesday, it appears as if Jonathan Toews will have Nick Schmaltz and Richard Panik as his linemates for the third consecutive game.

That must feel like an eternity given how often coach Joel Quenneville has churned his lines this season specifically Toews' line, on which almost every winger on the roster (and some currently in Rockford) has gotten a turn.

Toews' scoring numbers (10 goals, 20 assists) are down, in part because of an ailing back that plagued him early in the season and sidelined him for nine games in November and December.

But he also has changed linemates this season and last season, too, for that matter more than he anticipated when the Hawks traded Brandon Saad to the Blue Jackets in the 2015 offseason.

"I would never have predicted that my line would change as much as it has," Toews said. "Give credit to (Saad) he's a great player and a lot of fun to play with but you can't look at one thing like that and hang your hat on that excuse. It's up to me to find that consistency with whoever I'm playing with."

Toews is always one to put the onus on himself first and foremost, and he knows his $10.5 million salary carries with it a burden to produce. But he admitted the revolving door has made it hard to develop chemistry over multiple games the way Artem Anisimov, Patrick Kane and Artemi Panarin have blossomed together.

"As good as they've been, you don't really remember them for the game they might have been off or they didn't score," Toews said. "You give them some time to recover and they'll get back on the horse and get their offense going.

"Sometimes it is tough when you have to start that chemistry over. Sometimes it's midway through games or it's a couple times per week. Sometimes, even if I go a few games without scoring or producing, it'd be nice to start to build that chemistry and start to know where the other two guys are on your line.

"It's no knock against myself or anybody that I've been on a line with. It's about building that chemistry, being predictable for each other."

But Quenneville keeps tinkering with the lines every so often. And if general manager Stan Bowman is true to his word that the Hawks do not plan on making a big splash at the trade deadline, Toews might not have another headliner, such as Andrew Ladd a season ago, to play with come March.

"That's kind of a feel thing, and sometimes the record will dictate how long they stay together," Quenneville said. "Is it progressing where it looks like it'll come together? And it looks like it could have some staying power? With him, we always want to make sure we give it enough chance at least to survive and exist."

Toews likes his current line iteration. Schmaltz has been playing better over the last month during his second stint with the team, while Panik and Toews have formed a formidable combination in the past. Ultimately, though, Toews said it's on him to make it work.

"It's up to me to take ownership and play the best game that I can every single night and make sure that consistency is there," Toews said. "Then when it comes down to it, that's Q's decision who he thinks I should be out there with. I'll leave it at that."

Trump: ‘Good Chemistry’ With Japan’s Leader, ‘Getting Along Very Well’ With China – ABC News

Posted on by

President Donald Trump and Japanese Prime Minister Shinzo Abe in a joint appearance in the White House's East Room reaffirmed the importance of the two countries' "very crucial" security alliance in the Pacific region and their economic relationship.

Trump also in the press conference Friday afternoon gave his first public remarks about his phone call with China's president, Xi Jinping, on Thursday.

I think we are in the process of getting along very well, and I think that will be very much of benefit to Japan," said Trump who as president-elect made waves by speaking directly with Taiwan's president in a break with decades of U.S. practice. "Discussed a lot of subjects. It was a long talk. We are working on that as we speak. We have conversations with various representatives of China. Think it will work out very well for everybody.

The press conference was Trump's first during a difficult week for the White House. On Thursday night, the Ninth Circuit Court of Appeals denied a request by the Department of Justice to lift a stay on Trumps controversial immigration executive order.

The president on Friday reiterated his position that the White House will ultimately "win that particular case."

"We are going to do whatever is necessary to keep our country safe," Trump said. "Well be doing something very rapidly having to do with additional security for our country. Youll be seeing that sometime next week."

Prior to the press conference, Trump and Abe met in the Oval Office where Trump complimented Abes handshake and strong hands before walking together down the Colonnade. Trump noted that the two developed a friendship during a prior meeting at Trump Tower in New York and have very, very, good chemistry.

The bond between our two nations and the friendship between our two peoples runs very, very deep, said Trump.

This administration is committed to bringing those ties even closer," he said. "We're committed to the security of Japan and all areas under its administrative control and to further strengthening our very crucial alliance. The U.S.-Japan alliance is the cornerstone of peace and stability in the Pacific region.

Abe noted that this was his fourth visit to the United States in six months. In December, he met with former President Obama in Hawaii on the anniversary of Pearl Harbor.

In his remarks, Abe complimented Trump on his unusual rise to the presidency and business skills.

Donald, president, you are an excellent businessman, but you have never been in the Congress or been a governor. You have not experienced being in the public office, but you have fought the uphill struggle and fought for more than a year in the election campaign to become a new president, and this is the dynamism of democracy.

While traditionally friendly, the relationship between the U.S. and Japan got off to a rocky start when Trump signed an executive order withdrawing the United States from the Trans-Pacific Partnership during his first days in office. The move was met with disappointment by Japan who saw the T.P.P. as a check on Chinas trade power in the Pacific.

On T.P.P., of course we are fully aware of president Trump's decision. On the economic issues, we will be discussing at the working lunch that follows, said Abe. He added that the purpose of T.P.P. was a free and fair common set of rules for free trade regime in the region, and that importance has not changed.

Trump has touted his plans to increase infrastructure development, an idea he said is under discussion with Abe. Over the past year Japan said it has made more than $150 billion in new investments in the United States. Abe noted potential plans to build a high-speed train between Washington, D.C. and New York.

I'm sure there will be major-scale infrastructure investments that will be made, including the fast-speed train," Abe said, adding that Japan, with its high level of technical capability "will be able to contribute to President Trump's growth strategy.

Trump also said that big announcements are going to be made soon about companies "coming back" to the United States.

Ever since I won the election, and became president-elect, I've been telling companies, car companies and other companies, many companies, 'Come back into the United States,' and they've been coming back in, and big announcements are going to be made over the next short period of time, the president said.

Trump and Abe additionally discussed their commitment to combating terrorism and checking the threat of North Korean aggression in the Pacific region.

Our country is committed to being a fully engaged partner, said Trump. We will work together to promote our shared interests, of which we have many, in the region, including freedom of navigation and defending against the North Korean missile and nuclear threat, both of which I consider a very, very high priority.

In a lighthearted moment, Abe, whose name is pronounced ah-bay, said Americans sometimes mistakenly pronounce his name like that of Abe Lincoln. But that is not bad because even in Japan everybody knows the name of the great president, said Abe. That former carpenters son that became a president, and that fact 150 years ago surprised the Japanese ... The Japanese opened their eyes to democracy.

Following the press conference, the two leaders departed on Air Force One for Trump's Mar-a-Lago Club in Florida, where the president is entertaining Abe and his wife Akie. Both countries' leaders are golf enthusiasts and are scheduled to play a round together Saturday afternoon.

Abe joked that his game isnt up to par with Trumps. My scores in golf are not up to the level of Trump at all but my policy is never up, never in but always aiming for the cup.

Chemistry keeps Morristown clicking as season enters homestretch … – NJ.com

Posted on by

RANDOLPH Between the lines, the key to Morristown's 47-23 win over Jefferson in Friday night's Morris County Tournament final was its dogged defense.

But if you ask head coach Jim Pisciotti, the reason's for his team's success extend far beyond the Xs and Os they put ondisplay at the County College of Morris.

"The season has not been long for us," Pisciotti said. "We still compete in practice, we still watch our film, we still have fun together. When you say, 'What's the biggest thing?' We enjoy each other's company, the kids do. And it's just a product of their hard work."

That simple fact has helped breed a culture within the Morristown squad no player ever walks off the court thinking she should have had more touches, more shots, more minutes.

Instead, the Colonials focus on a basic tenet of the game: teamwork.

"As good as we are individually, we're better together," Pisciotti said. "I guess that's the best compliment I could give them. When you look at us individually, we're pretty good but when you put us together, suddenly we're better. That just goes to their chemistry."

So far, it's worked to perfection after all Morristown has already taken its conference and county titles.

Now, attention turns toward theNorth 1, Group 4 title chase. Butwhatever happens, the Colonials know they've already foundsomething special this season.

"Honestly, it's the best group of girls I could ask for," senior Elizabeth Strambi said. "It's not only the basketball off the court, we're all going over to one girl's house. These are my best friends."

Draymond Green vs. Kevin Durant? The Warriors’ chemistry is built on trust, respect, and yes, the occasional public … – The Mercury News

Posted on by

OAKLAND Sometimes, the Warriors just have to yell at each other for a little bit. Good and loud. Make a scene.

Doesnt matter that theyre winning more than 80 percent of their games and maybe the edgiest Warriors bark at each other precisely to keep the competitive fire burning while theyre winning more than 80 percent of their games.

Nobody takes anything personal, Stephen Curry said after practice Tuesday when asked about the most recent Warriors blow-up between Draymond Green and Kevin Durant. Nobody goes home and cries about it.

It can happen behind closed doors or during practice; it can be between two of their biggest stars; and on Saturday in Sacramento, it happened during the Warriors flat loss to the Kings, during a timeout, when Green pretty clearly was looking to light a fire under Durant, who was in the middle of his worst game this season.

Durant answered back, Green kept going, and it all produced 30 seconds of very interesting video, possibly most notable for the lack of urgent reaction by their teammates.

Nobody ran in between them (Shaun Livingston did some brief mediation) and nobody seemed too startled or alarmed, because this is how the Warriors operate they know there will be more of these arguments because they want there to be more of these.

Clear the air. Nothing gets swept under the carpet. Then move on.

If you cant (have these kinds of arguments), youre probably on a losing team, Green said Tuesday. But everybody who makes a big deal out of it probably are losers.

So thats how I view it. Anyone who knows anything about winning knows thats going to happen.

Green also made some headlines when he had words with Durant in the final moments of the Warriors loss to Memphis Green wanted Durant to set a screen for Curry in a key possession and Durant decided to keep the ball and attack on his own.

By the way, Green and Durant are close friends, after bonding during the Olympics last summer; they sit next to each other on team flights and, according to ESPN, watched the Super Bowl together the day after the Sacrament squabble.

Durant was not available to reporters on Tuesday because he sat down for a long interview with ESPN to preview Saturdays big return to Oklahoma City.

But generally, the Warriors laughed off any presumption that those 30 seconds were any serious disruption of team chemistry. In fact, its all part of the chemistry.

Totally normal, coach Steve Kerr said. You shouldve seen the Bulls back in the day. We had guys yelling at each other.

A little history here: Kerr and Michael Jordan engaged in an infamous practice brawl in the early part of the 1995-1996 season that would lead to a then-record 72 regular-season victories and a championship and Kerr and Jordans long friendship essentially began immediately after that fight.

I equate it to, if you have a lot of siblings and youre in the house together every day and you love each other and youd do anything for each other, but youre going to get in fights, Kerr said of the Green-Durant moment.

Thats what its like to be on a team. These guys are so close. Imean, KD and Draymond are best of friends and theyre together every night laughing and joking. So when something happens on the floor, I dont even bat an eye.

The marquee part of this that it was Durant and Green, of all people is what makes this uniquely uncomplicated for the Warriors.

It comes from a place of respect, Curry said. Its nothing thats going to boil over to anything where it gets out of control. We understand what it is. And its all geared towards getting better.

Green can give it to Durant because Durant can dish it back, and if theyre comfortable enough to let everybody see it, then it becomes something like a team-wide pressure release.

I think all that stuff is healthy, Kerr said. Its healthy for the guys at the end of the bench to hear me getting on Steph or KD or Draymond about missing an assignment; its healthy for them to see the players hash everything out even in a heated way.

Were trying to fix whatevers going on. And theres always a line, right? You cant cross the line. And I think our guys do a good job of walking that line and bouncing back the next game and its never been an issue.

Plus, when Green is the emotional leader of the team, there will be no passive-aggressive messages or pent-up emotions.

If youve got to hide something from one of your teammates and you cant say something to somebody, then youre in a bad situation, Green said.

And me personally, I dont want to be in that situation If there is a team like that, please make sure Im on the first thing smoking out of there. Because that team aint for me.

Maybe there are teams like that, but the Warriors arent one of them, which is a vital part of who they are, how they get along so well and win so much, and also why they yell at each other occasionally.

IOCDs One-World Chemistry initiative is part of the organizations efforts to promote chemistry for better health and a better environment and to strengthen education in the chemical sciences.

Credit: IOCD

An editorial in Nature Chemistry in 2010 asked chemists a simple question: Where are the champions? The opinion piece highlighted long-held misconceptions and negative perceptions about chemistry and observed that chemistry lacks the easily articulated grand challenges associated with physics or biology, and it generally gets a rough ride in the mainstream media. All the more reason that it needs effective advocates and champions.

The International Year of Chemistry held the following year does not appear to have achieved the hoped-for change in chemistrys standing in the publics eye, to have raised the profile of the subject, or, with a few exceptions, to have inspired champions of chemistry to step forward. Moreover, a Royal Society of Chemistry study in 2015 revealed that chemists image of how society views the subject was worse than the reality. These results seem to us indicative of a profession afflicted with low self-esteem rather than one confident to undertake effective advocacy on its own behalf.

Against this backdrop, chemists need to ponder ways to reenergize and refresh their profession in a form that will be suited to meeting oncoming challenges. We should reflect on the question, where are the champions? It is inextricably linked to the equally important question, how do we champion chemistry? And both of those questions raise the further question, what is the nature of the chemistry that should be championed?

It has become evident to us that chemistry must create a fresh idea of its position and purpose and develop around this idea a coherent, collective effort to encourage, promote, and project new messages in the field and outward to society at large. Our intent is to stimulate a debate to address emergent concerns and to suggest a nuanced agenda for rejuvenation for the chemistry community and other stakeholders, particularly policy-makers, to consider. The aim of this effort is the promotion and advancement of the discipline to ensure that its creative power and reach are fully harnessed for the well-being of our planet and people.

The canvas of chemistry being unlimited, it fulfills several essential roles: as a science contributing fundamental knowledge of the properties, behaviors, and transformations of atoms and molecules; as an underpinning for adjacent sciences that depend on understanding molecular structures and interactions; and as a source of a vast range of useful products and applications. But this very breadth and diversity of capacities make it hard to encapsulatefor the big picture to emerge and for the human angle to be appreciated.

Our concept and approach, which we call One-World Chemistry, has been put forward as one framework for accomplishing these goals. One-World Chemistry incorporates three basic principles. This first is that in pursuing the chemical sciences, it is essential to develop awareness of how chemical systems interact with many other systems, including the physical, biological, and ecological systems of the planet. It aims to position chemistry as a science pivoted on the human activity-ecosystem interface.

The second principle follows from the first and recognizes that the solutions to many fundamental and applied problems traverse geographic and disciplinary boundaries and mandate cross-disciplinary approaches. The third and overarching principle is that chemistry must at all times be practiced in an ethical manner, taking account of the short- and long-term impacts both of how it is conducted and of the uses, potential uses, and fates of its products and by-products.

These principles have consequences for the teaching and practice of chemistry, which need to adopt systems thinking as a core perspective and reinforce ethical behavior and skills in cross-disciplinary approaches from an early stage.

This framework makes it inevitable that chemistry will seekand project itself as being concerned withlinks to major global concerns, such as finding environmentally benign ways to generate energy, creating new materials while conserving natural resources, devising processes with a minimal carbon footprint, developing new drugs for neglected and emerging diseases, and overcoming challenges of drug resistance. It also presents opportunities for creating and publicizing grand challenges that frame chemistry as a positive and proactive contributor to meeting oncoming societal needs instead of just waiting for disasters to make news headlines that present chemistry as the culprit rather than the solution.

Clarity about the position and purpose of chemistry is an essential prerequisite for determining who can be the champions of this inclusive, ethical, and sustainable new world. Our conclusion is that everyone must become champions: individual chemists, academic departments in colleges and universities, chemistry societies, environmental advocacy groups, government agencies, and industry. They must act both individually and collectively through coordinated initiatives.

Within this overall shared responsibility, championing can be given leadership and afforded stronger public appeal and greater impact by encouraging the emergence of role models and skilled advocates. Chemistry lacks well-recognized voices such as those of Craig Venter for genomics research and Stephen Hawking for cosmology. Statesmanlike celebrity chemists can and should contribute significantly by capturing broad attention in the media, galvanizing societal esteem, and igniting young minds to project the dimensions of chemistry in all its diverse roles. Of course, the champions may be important and busy people devoting their time to doing great science. But it is incumbent on them to give attention to and communicate about the field that sustains their creative urges and provides the basis for their visibility and careers.

Such advocacy can be supported and encouraged by everyone associated with the chemistry enterprise. In particular, champions from industry need to be able to overcome challenges in how companies are perceived by a skeptical public. Many people recognize that the chemical and pharmaceutical industries are major drivers of the global economy, but they also know these manufacturers are major consumers of raw materials and sources of pollution that cause environmental damage.

The adoption of green chemistry approaches by sections of the chemical industry has been a step in the right directionand one that can actually be cost-effective rather than a cost accelerator. Embracing the principles and practice of One-World Chemistry offers industry the opportunity to radically reform its image and operations and to position itself in a new light as the champion for sustainable development and the source of solutions to global challenges.

It is crucially important that chemistry is projected both as an exciting fundamental science and as an ethical science for the benefit of society, one whose central goal is human well-being and the well-being of our planet. All who are associated with the chemistry worldthat means all of usshould take up the challenge of championing this view.

Ocean chemistry changes triggered Earth’s greatest extinction event – Chemistry World (subscription)

Posted on by

The mixing of sulfide and oxygen-rich waters in the prehistoric Panthalassic Ocean contributed to the largest mass extinction of the last 540 million years. These new findings by Chinese and US researchers still have relevance today, as present-day climate change is exacerbating the growth of sulfidic zones in the worlds oceans.

Around 252 million years ago, the end-Permian event wiped out nearly all life on Earth in the most devastating extinction event in the planets history. More than 80% of marine species disappeared and it took several million years for these ecosystems to recover.

At this time the Panthalassic Ocean spanned 70% of the Earths surface. Today, the ocean floor that once sat under the Panthalassic has almost completely disappeared, with the only preserved sediments found in Canada, Japan and New Zealand. Using samples of fools gold found in these deposits, a team of geochemists led by Yanan Shen, of the University of Science and Technology of China, has tracked the changes in ocean chemistry that drove this catastrophic extinction event.

By analysing sulfur isotopes in pyrite minerals, the team concluded that the main killing agents were brought about by the mixing of sulfide-rich waters from the deep ocean with oxygenated shallow waters. Exactly what caused this increased mixing is still a mystery, however. Sulfide is toxic to eukaryotic cells and we know that hydrogen sulfide at concentrations of a few hundred parts per million would be lethal to humans, if exposed for a prolonged time, explains Shen. The shoaling of sulfidic waters, therefore, would kill marine animals in the PermianTriassic oceans.

Timothy Lyons, a biogeochemist from the University of California, Riverside, US, who was not involved in the research, describes the findings as tantalising. He explains that by measuring four different sulfur isotopes the researchers could fingerprint specific sulfur metabolic microbial pathways, gaining insight into the prehistoric oceans chemistry. When viewed in a temporal context, [the data] points to highly dynamic conditions and major perturbations to the marine system, he says. Evidence for episodic intrusions of sulfide into shallow waters may be the smoking gun for both the mass extinction and the protracted biotic recovery that followed.

Although the end-Permian extinction happened over a quarter of a billion years ago, the events that triggered it have added significance in the light of current-day climate change. Satellite remote sensing has clearly shown that massive fish mortality in the Namibian coastal waters are associated with sulfidic waters, says Shen. As a matter of fact, due to human-induced eutrophication and global warming, the episodic occurrence of hydrogen sulfide has been reported in many coastal waters such as those of the Gulf of Mexico, California and western India.

This warning is echoed by Lyons, who notes that there are lessons to be learned from this event, as we face warming in the present-day ocean.

Atlanta United working on chemistry – AJC.com – Atlanta Journal Constitution

Posted on by

Jeff Larentowicz has been part of one team that won an MLS Cup, and another that played in the league finals three consecutive years.

He said one of the keys to those teams, and something he saw developing in the first few days of preseason training with Atlanta United, which he joined as a free agent, was chemistry, that elusive and nebulous gel that can turn teams with good talent into great teams, or if its missing can turn a group of talented players into a poor team.

It seems weve got that going from the start, said Larentowicz, who has 324 appearances in MLS since 2005. Obviously, things change when points are up on the board. For now, its good.

Thats exactly what Atlanta United President Darren Eales, technical director Carlos Bocanegra and manager Gerardo Martino hoped would happen when the decision was made to sequester the expansion team away from friends and family for its first preseason camp.

The team has signed more than 25 players, of which only a handful of pairs (Larentowicz and Michael Parkhurst at New England; Harrison Heath and Mikey Ambrose at Orlando; Tyrone Mears and Chris McCann were teammates at Burnley; Alec Kann and Jacob Peterson Sporting Kansas City and Kann and Larentowicz were teammates at Chicago) have been teammates on a club before.

Theres a lot they dont know about each other, and a lot they may need to know if the club hopes to become the first expansion team to make the MLS playoffs since Seattle in 2009.

This will be a good setting for them to build trust and get to know each other, Martino said during the first week of camp.

Eales said when he Bocanegra first began to talk with Martino about possibly becoming the teams manager, the Argentine wanted a training camp environment during which he could have as many training sessions as possible. The team has had more two-a-day sessions than single-session days since camp started on Jan. 24.

Its almost like greenhouse, having to artificially grow that chemistry, Eales said.

The original plan was to use the home of the Falcons in Flowery Branch as the site. But, Eales and Bocanegra happily say that plan changed because of the teams run to the Super Bowl.

The team instead moved its training camp to IMG Academy in Bradenton, Fla. for two weeks. The players stayed in villas on campus and spent most of their days learning Martinos style and personality, that of his assistants, and that of each other.

Bocanegra knows the importance of his chemistry and training camp from his storied career as a professional that included playing for teams in the U.S., Scotland, England, Spain and France. Players were grouped in the housing to try to get to know each other. Andrew Carleton and Chris Goslin, the teams first two Homegrown Players whose playing time will likely come as reserves if at all, were in a group with Hector Villalba, the teams first Designated Player who will likely start.

When you are here all day, every day for two weeks you get to know the good, bad and ugly about everyone, Bocanegra said. You get a feel for what kind of people they are, what kind of personalities they have, their tendencies off the field as well. It helps to develop chemistry in the locker room, as well.

These are the little thing that develop within the team. Its really about getting to know each other.

Chemistry values communication. Because Martino is learning English, he will give his instructions during practice in Spanish. An assistant standing in the middle of the field will repeat the instruction in Spanish. Two more assistants, one at either end of the field, will repeat them in English. Some words, Bueno, need no translation. The coaching staff has started English lessons. The players who dont know English will start learning when the team returns. Though, because of the roommate situations, some may already be learning. Carleton and Goslin, whose primary language is English, said they are trying to teach Villalba, whose primary language is Spanish, about college basketball.

You come in and you are curious, Larentowicz said. You dont know what to expect from each other, the staff, the preseason in general, from a lot of the guys, from MLS. We are starting to get over the hump and figure out who we are.

The chemistry experiments arent just limited to the field.

Eales said they have planned on different speakers to come and talk to the team about different topics when they report to Flowery Branch. Owner Arthur Blank has already addressed the team and will likely do so again. Steve Cannon, the CEO of the Arthur M. Blank Group, will discuss his journey from West Point, the Army and as CEO of Mercedes-Benz USA. Lastly, Eales is hoping that Falcons coach Dan Quinn will have time to share the Falcons journey to the Super Bowl and how his team came together.

Lastly, happy wife is supposed to lead to a happy life.

Eales wife and Bocanegras wife are starting a family association to help the spouses and girlfriends of the players feel comfortable in the city and with the challenges of moving, and with the team. Eales said at least one training session a month will be open for the family members to come and watch.

We are trying to make players feel a part of the team, but their families as well, Eales said.

Constraining the chemistry of carbon-chain molecules in space – Phys.Org

Posted on by

February 27, 2017 An image of the Taurus Molecular Cloud, about 450 light-years from Earth. Many carbon-chain molecules have been detected towards dark clouds like these, but astronomers have sought HC11N without success. They speculate that chains this large preferentially transform into carbon rings. Credit: ESO; Digitized Sky Survey; Davide De Martin

The interstellar medium of the Milky Way contains 5-10% of the total mass of the galaxy (excluding its dark matter) and consists primarily of hydrogen gas. There are small but important contributions from other gases as well, including carbon-bearing molecules both simple, like carbon monoxide and carbon dioxide, and complex like ethene, benzene, propynal, methanol and other alcohols, and cyanides. There are even some very large molecules like polycyclic aromatic hydrocarbons and buckyballs with fifty or more carbon atoms. Some species like the cyanides have relative abundances similar to what is seen in comets in our solar system, suggesting that local carbon chemistry is not unique.

Astronomers think complex interstellar molecules are probably produced on dust grains, although some molecules might be produced in the gas phase. About one percent by mass of the interstellar material, these tiny grains are composed predominantly of silicates and provide the gas molecules with surfaces on which to react with other molecules. Carbon chain molecules are particularly interesting because they are thought to be the starting point for a significant fraction of the known complex chemicals in the interstellar medium. It is even suspected that carbon-chain species are a key stage in the formation of polycyclic aromatic hydrocarbons. Carbon-chain molecular chemistry thus provides insight into a large subset of interstellar chemistry.

A particularly well-studied family of carbon chains is the cyanopolyynes: linear molecules of the form HCnN, where n = 3, 5, 7, 9, etc. They have been observed in high abundance towards older stars and in cold dark clouds. The presence of the largest known cyanopolyyne, HC11N, however, is in dispute. It was reportedly detected in 1982 towards one dark cloud in Taurus, but that detection has not been confirmed. CfA astronomers Ryan Loomis and Brett McGuire and their colleagues used the Green Bank Telescope to search the Taurus region for HC11N in six of its characteristic radio wavelength transitions, including the two in which it was first reported, but without success.

The astronomers argue that the previous detection was an error, and they offer an explanation for the otherwise curious absence of the n=11 species. Laboratory experiments have shown that when carbon-chain molecules get to be longer than about n=9 they begin to curl on themselves and preferentially transform into carbon-ring molecules, which are more stable. A similar process could be occurring in the interstellar medium, siphoning away HC11N to form cyclic species. The non-detection of HC11N thus suggests the importance of this chemical pathway in producing cyclic molecules, although the authors note that further observations and laboratory experiments are needed to confirm the model.

George A. Olah, who won Nobel Prize in chemistry, dies at 89 – ABC … – ABC News

Posted on by

George A. Olah, whose work won a Nobel Prize in chemistry and paved the way for more effective oil refining and ways of producing less polluting forms of gasoline, has died at age 89.

Olah died Wednesday at his Beverly Hills home, according to the University of Southern California's Loker Hydrocarbon Research Institute, of which he was founding director. No cause of death was provided.

Olah's research brought him the 1994 Nobel Prize in chemistry for his groundbreaking study of the unstable carbon molecules known as carbocations.

"Distinguished professor George Olah was a true legend in the field of chemistry," USC President C. L. Max Nikias said in a statement Thursday. "His pioneering research fundamentally redefined the field's landscape and will influence its scholarly work for generations to come."

The Hungarian government offered its condolences for Olah, who fled Hungary during a 1950s Soviet crackdown on dissent.

"The country has lost a great patriot and one of the most outstanding figures of Hungarian scientific life," said Janos Lazar, chief of staff to Prime Minister Viktor Orban.

Olah received the Nobel Prize for his work on superacids, research that led his observation of carbocations an unstable, fleeting chemical species that he discovered how to stabilize long enough to study its properties.

He said there was no "eureka moment" and credited the find to long hours spent in his chemistry lab, usually starting before dawn and continuing late into the night.

He also singled out for praise his longtime USC collaborator Surya Prakash, who began working with Olah in the 1970s as a 20-year-old grad student and now leads the Loker Hydrocarbon Research Institute.

Born in Budapest on May 22, 1927, Olah said he had little interest in chemistry as a youngster.

"My main interest was in the humanities, particularly history, literature, etc.," he said in a statement published on the Nobel website. "I was (and still am) (an) avid reader and believe that getting attached too early to a specific field frequently shortchanges a balanced broad education."

Instead he studied Latin for eight years as well as German, French and other languages. The son of a lawyer said he was fortunate to attend a school he called one of the best in Budapest.

It was at the Technical University of Budapest where his interest in science was finally piqued.

After earning a doctorate in organic chemistry, he went to work for the Central Research Institute of the Hungarian Academy of Science.

He was leading a research team there in 1956 when the Soviet Union cracked down on the country following the Hungarian Uprising of that year. He, his wife, their young son and most of his research team fled the country.

Eventually moving to Michigan, he began research on carbocations while employed by Dow Chemical Co. Later he taught at Cleveland's Western Reserve University before moving to USC in the late 1970s.

Honored by numerous scientific societies as well as his native country, Olah authored or co-authored nearly two dozen books and published nearly 1,500 papers. He held 160 patents from seven countries, according to USC.

He is survived by his wife, Judith Olah, sons George and Ronald, and several grandchildren.

The university plans a campus celebration of his life at a later date.
