The Nucleus: Crash Course Chemistry #1

Posted on by

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

CHEM0821. Chemistry of Wine. 3 Credit Hours.

Wine has occupied a central role in human culture. In our exploration of the science of wine we will learn why wine was the beverage of choice through the ages, why a bottle of wine can range from $2 to $2,000, how wine is made, what makes a good/bad wine, how is white different from red, and how we know what is in a bottle of wine. The course begins with a large scale fermentation of red and white wine and will continue with team-based analyses of the two month process of turning grape juice into wine. Many aspects of the production and consumption of wine will be addressed in this course. NOTE: This course fulfills a Science & Technology (GS) requirement for students under GenEd and the Science & Technology Second Level (SB) requirement for students under Core.

CHEM0838. Nature Has No Reverse. 3 Credit Hours.

Rapid advances in modern science often tend to conceal the "forest in the trees," but we all need enough familiarity with the "scientific method" to make informed judgments as citizens and voters. This course will take you on a journey through the history of science, with stops at the Second Law of Thermodynamics, the "revolution" of fire, the rational basis of life, energy as the universal currency and changes in the universe around us. We will end with that most disturbing of paradoxes: the certainty of uncertainty. Each week includes both lecture and hands-on demonstration/practicum.

CHEM1055. Introduction to Problem Solving and Logical Thinking for Pre-Medical Post-Baccalaureates. 1 Credit Hour.

The ability to solve problems and think logically is essential for success in health professions schools because health professionals must be able to put together patient symptoms, test results, and current research to determine the best course of action for the patient in question. As a result, entrance exams for health professions schools test the ability to think and solve problems logically. However, the techniques of good problem solving are rarely explicitly taught at any point in a student's education, and science majors rarely take logic courses. This course seeks to fill that gap in a way that is geared specifically toward what is needed for pre-health students to succeed in their classes and on standardized tests. This course teaches students good problem-solving techniques and the basics of deductive and inductive logic. The students will spend class time practicing and applying the techniques and principles they are taught, either individually or in pairs/groups. This design will enable them to develop their skills of problem solving and logical thinking so that they can apply them not only to their classes, but to entrance exams for professional school and the practice of their profession as well.

The LA Clippers team chemistry appears to be on the rise – Clipperholics

Posted on by

NBA teams change every offseason, but the LA Clippers roster experienced one of the most drastic (if not the most drastic) shake-ups in the league this summer.

All-Stars Kahwi Leonard and Paul George made the move to LA along with veteran roleplayers Maurice Harkless, Patrick Patterson, and Rodney McGruder. Despite all these new faces, the team already looks comfortable playing, and more importantly, winning together.

Ramona Shelbourne of ESPN received the following information from head coach Doc Rivers:

Skeptics may claim that Rivers is exaggerating, but with 80 games left in the regular season, this is entirely possible. Plus, who knows players better than their coach?

With George out, Lou Williams becomes the Clippers next best scorer. He played 36 minutes and 43 seconds in the season opener, going 8/14 from the field for 21 points, five rebounds and seven assists. Leonard played 31 minutes and 11 seconds and hit 10/19 field goals for 30 points, six rebounds and five assists. Leonards three-point shot was faulty, as he hit just 1/5, but his 9/10 shooting from the charity stripe was appreciated.

Both Williams and Leonard can move the ball to the rest of the team and take smart shots, making the LAs offense successful even without George. In fact, the Clippers ball-movement has the potential to be the best its ever been, all thanks to the trust each player has for the next.

Leonard trusted his teammates enough to rack up a career-high nine assists against the Warriors Thursday night.

Other players on the roster such as Montrezl Harrell, Patterson andLandry Shamet may even start to carry some of the offensive load that Leonard and Williams have been expected to share.

Each players ability to accept their role will also grow the teams chemistry. The more comfortable each player is with their job, the more comfortable and consistent the teams offense and defense will be.

Patrick Beverley knows that his energy on defense is a huge asset, while players like Patterson and Harkless have accepted their roles as rotation players. Harkless started in 53 games for the Portland Trail Blazers last season but looks comfortable on both ends of the court coming off the bench. He is as good of a backup small forward as any.

There are a lot of NBA fans and personalities who have high hopes for the LA Clippers this year, and no doubt, their growing chemistry will help the team reach their championship goal.

Notes: Villa Park hopes to keep chemistry grade high after transfers – OCRegister

Posted on by

Coach Dusan Ancich said his Villa Park football program returned from its team-bonding trip to Hawaii closer than ever before. But that chemistry will be tested after three talented transfers recently arrived from Corona High.

The Spartans have added USC cornerback commit Marcus Johnson (5-10, 175), linebacker/running back Zechariah Holifield (6-0, 220) and rising quarterback Shane Illingworth, a 6-foot-6, 225-pound sophomore, in recent days.

Johnson and Holifield are seniors who are moving into the Villa Park area so they could be eligible soon, Ancich said. Illingworth will observe the CIF-Southern Sections sit-out period, so look for junior Paul Piferi (6-5, 198) to remain the starter until at least until Oct. 6.

One of the lesser-publicized effects of transfers is the displacement of established players, which in turn could challenge team chemistry.

Ancich said the best 11 players will play for the Spartans (1-0), who take on host Redondo (0-1) on Friday.

We have two Division I quarterbacks, Ancich said. If everybody gets cleared, does things right, above board (and) we keep our team bonding and philosophy, it should be fun. Its a great surprise for us.

The Illingworth family is familiar with Ancichs coaching philosophy. Shanes cousin, Devon, played defensive end for the Spartans. His father played for Ancichs father, Marijon, at Tustin.

Everybody is treated the same, Dusan Ancich said. We give a depth chart every week. Its always the best 11 (who start). Thats just a black-and-white deal.

THOUGHTS ON HOUSTON

All of the high schools in the Houston area have canceled their Week 1 games because of the damage from Hurricane Harvey.

If displaced families arrive in the Southern Section, students could receive a hardship waiver to gain eligibility, section spokesman Thom Simmons said Monday.

Former El Dorado quarterback Kane Wilson was displaced by Hurricane Katrina in 2005 before arriving at the O.C. school as a freshman.

NOTES

La Habra and Yorba Linda are among the area teams that have moved practices Tuesday and Wednesday to the evening because of the expected heat wave.

Sonora finished 0-10 last season but opened with a 19-8 win against visiting Whittier.

Raiders coach Daniel Morales praised several players, including running back/linebacker Chandler Thompson and quarterback Ryan Martinez. Our defense played really tough, Morales said. I was so happy how they were challenged in our own territory quite a few times but didnt break.

Cal commit Chigozie Anusiem had four receptions for 87 yards and a touchdown and also played defense and special teams.

La Habra (0-1) is looking to bounce back from a 35-7 loss at Upland that Highlanders coach Frank Mazzotta called humbling. We have to get a lot better in a hurry, said Mazzotta, whose team plays host to Tesoro on Friday.

Tesoro coach Matt Poston said sophomore Kyle Schaefers helped the Titans as they nearly upset Edison before losing 48-47. He had 90-yard kickoff return for a touchdown and played well at cornerback.

Mission Viejo plays host to the Brothers in Arms Classic on Thursday through Saturday. Servite plays American Fork of Utah on Friday at 5 p.m. while the Diablos take on former CIF-SS rival Vista Murrieta at 8 p.m. American Fork is nicknamed the Cavemen.

Reigning CIF Division 1 champion St. John Bosco (0-1) plays Garces of Bakersfield on Saturday at 8 p.m. at Mission Viejo.

The Father of Modern Chemistry Proved Respiration Occurred by Freezing a Guinea Pig – Smithsonian

Posted on by

Antoine Lavoisier gave oxygen its name, from the Greek words for acid-former. But that wasnt his only contribution to scientific understanding of what it does.

Born August 26, 1743, Lavoisier is considered the father of modern chemistry, according to University of Missouri Libraries. He was one of the first people to relate chemistry to the science of bodies, physiology, and study what we now call metabolism and respiration. One of his most memorable proofs that bodies underwent some of the same processes as the world around them was the time he froze a guinea pig.

Oxygen was first isolated by Joseph Priestley, a British chemist studying air, in 1774. Priestley called it dephlogisticated air, because he thought it was pure air that lacked phlogiston, an element that eighteenth-century scientists thought was produced by something burning but was also present in normal air.

Lavoisier didnt think that Priestley was right about phlogiston, prompting a long-running battle. Lavoisier didnt believe Priestley because of his own groundbreaking approach to chemistry. Lavoisier believed that matteridentified by weightwould be conserved through any reaction, writes Chemical History. Today this is known as the law of conservation of mass. What it means is that the same amount of matter that goes into a chemical reaction comes out of it. This central belief led him to study how the gases present in air related to fire and to breathing.Writing for io9, Esther Inglis-Arkell explains how this led Lavoisier to torment the poor rodent.

Lavoisier noticed that, just like a fire, people and animals seemed to warm themselves. Also like a fire, if people stayed in an unventilated room, they would eventually transform the air into a gas that smothered them. Lavoisier realized that the two processes, a fire burning and people breathing, were equivalent. Although he couldn't prove the chemistry involved, he could prove the basic physics. One of the main problems with his theory was that, unlike fire, animal-produced heat was so minor. How could it be measured?

Guinea pigs, which are native to modern Peru, had been in Europe for at least a few hundred years as pets for wealthy Europeans,writesMaev Kennedy forThe Guardian. Where Lavoisier got the guinea pig he used in the worlds first animal calorimeter remains a mystery. To measure the heat that was produced by breathing, he placed a guinea pig in a bucket that was nested inside another bucket filled with ice. The ice bucket was in turn nested in a bucket filled with snowwhich was just there to insulate the ice, writes Inglis-Arkells. The guinea pig didn't freeze to death, but was presumably pretty cold surrounded by all that ice.

Lavoisier collected the melted water, and when he at last got about a kilogram of it, calculated that the melting of the ice required about 80 kilocalories of energy from the guinea pig, she writes. He believed that the energy came from a process known as respiration, which turned oxygen into carbon dioxide and heat, the same way a burning piece of wood might.

Through this experiment, Lavoisier was able to demonstrate that respiration was a form of slow combustion, writes the University of Missouri Libraries. He continued exploring the ways that chemistry shapes bodies, even drawing links between food and metabolism, until his untimely death by beheading in 1794, during the French Revolution.

Weike Wang Combines Humor, Science, and Depression in Debut Novel ‘Chemistry,’ – NBCNews.com

Posted on by

As for Wang herself, she said she genuinely enjoyed working in the sciences, but still felt her fate lay elsewhere. I like research, but I realized that someone else could be doing that research, with my writing I felt like I could be the only one doing that, she said.

In addition to the books humor, reviewers have noted Wangs choice to keep her narrator nameless. Wang explained that the decision to do so was a deliberate one. When I think of a name it is very specific to the character and I didnt want that to happen, Wang said. Would I name her something Chinese or something American? I didnt want to deal with that.

Juggling multiple identities is something Wang has a bit of experience in. Born in China, she and her family moved to Australia when she was 7 and later moved to Canada and then eventually to the United States. When I write characters that are not open, its because Im not necessarily that open in terms of opening up to new people, Wang said. I made her like that in that she is just very lonely. And when you are lonely, you are not used to telling people how you feel.

Wang added that she has been a bit taken aback at how mean many readers and reviewers said they thought her narrators parents were. Noting that while her books fictional parents did have high standards and did not always understand their daughter (especially as she waffled in regards to her studies), they were not uncaring.

When you are an immigrant parent, Do I want to make my child happy? is not a question you always ask, Wang said. Its I need to feed her. I need to put a roof over her head. I need to make sure she has health insurance. My point is not to vilify them.

That view of family also shaped how Wang developed her narrators journey and subsequent contrariness. Its not the traditional rebel story. Its not like Im going to go travel to find myself or I am going to join a band.' Because everyone I know rebels quietly, she said. Its not F**k you, parents. Im just going to leave the country.' Its doing really tiny things. Because first, my parents would kill me if I did that and also, how am I going to get health insurance if I do that?

GenX: A Question Of Chemistry – WHQR

Posted on by

Listen to this story here

New Hanover County Commissioners adopted a resolution Monday calling on Chemours to stop production of GenX. Brunswick County Commissioners adopted a resolution the same day -- asking Chemours to stop the discharge of the GenX chemical into the Cape Fear River. Thats largely because there is still a lot about GenX that we dont know. Its all about chemistry. Which means for many of us, it can be somewhat difficult to grasp.

As a scientist, I rely on data, to inform my approaches, and my evaluations, and I dont have the data yet.

Dr. Susanne Brander is a toxicologist at UNC Wilmington.

She says to understand GenX, one needs to look at its predecessor.

And so the only way to have an idea of what could be expected from exposure to a chemical like that is to look at what is known about a similar chemical, and there has been a lot of talk about how GenX was the replacement for another chemical known as C8, also known as Perfluorooctanoic acid. A PFOA.

C8 is a confirmed carcinogen. Its been linked to a wide range of diseases and cancers. Thats why GenX was developed. C8 is a long chain of carbonfluorine bonds. In GenX chemists added an oxygen atom to the middle of the chain. The thinking was this would make the compound less persistent, and it would pass through the body more quickly.

Dr. Phillippe Grandjean is with the Harvard University School of Public Health, and also chair of Environmental Health at the University of Southern Denmark.

We know that they appear to have a short half-life meaning they are eliminated very rapidly. But the fact of the matter is yes they do leave the bloodstream, but that is because they are accumulated in the body, the liver the kidneys the lungs, and so just because some of them appear to disappear from the blood rapidly, that may not indicate that they have disappeared from the body as a whole.

He says GenX is easily absorbed.

So if you drink contaminated water these compounds will rapidly move into your bloodstream and be circulated so that they can reach all the organs of the body. We also know that these compounds can cause liver cancer, in rodents.

Its when the GenX molecule attaches to other cells, that health issues can arise, albeit years down the road. Dr. Larry Cahoon is with UNC Wilmington.

This is a molecule, GenX and its congeners, that is going to tend to bind to cell membranes including some of the receptors that normally would bind with the hormone molecules or some of the other signaling molecules.

And, Cahoon says, they are resilient.

These compounds dont break down. Biologically they are not broken down. Once they are loose in the environment, they are loose in the environment and thats it. You are not going to get rid of them, these compounds are persistent as they possibly could be.

Again, Dr. Grandjean.

So this is very parallel to what we knew about PFOA, C8, in the 1990s, and my concern is that if these new GenX compounds if they have properties, I would be concerned that there might be additional toxic effects.

The levels of GenX in the Cape Fear River remain a mystery. This week the states Department of Environmental Quality began a series of tests at 13 locations between the Chemours facility, and Wilmington. Those results should be available in a few weeks.

What the heck is ‘green chemistry?’ – timessentinel.com

Posted on by

My dad was a chemical engineer. In spite of that, I have a befuddled relationship with chemistry.

Its not love/hate, because I dont know enough about the elements to love or hate them. I took only one class as a senior in high school, but had been forewarned by my companions at my all-girls academy that the class was boring. Furthermore, it was taught by a quiet-spoken nun who was beyond retirement. I passed, barely.

I skirted chemistry in college by favoring liberal arts over science and was well into my gardening years before I realized that a little more knowledge of the periodic table would be helpful in knowing the connection between phosphorus and nitrogen, and whether potash and potassium (also in the NPK of garden fertilizer nomenclature) are the same. I regretted not understanding more.

Back in the 1970s, I discovered Monsantos Round-up was a powerful weed killer. I also learned it was a target of the organic homesteaders movement that I espoused. I quickly championed the harm that such chemicals can do to health. Reading Rachel Carsons discovery of the near-demise of the Bald Eagle because of DDT, I realized we have lived for thousands of years without plastic, flame retardant pajamas and Teflon non-stick pans. Why bother with such harmful chemicals now? I was a fervent anti-chemical activist.

I first learned the term from a teacher friend at Marian University when they established a green chemistry program. The EPA defines the practice of green chemistry as designing chemical products that are fully effective with little or no toxicity to either humans or the environment. Extraordinary! I wished I could have learned that kind of science. Its a win-win.

To that end, I have been trying to make up for my lack of basic knowledge about chemicals and their effects on humans and the earth. A three-part webinar starts this week that I am excited to see. Perhaps I will be enlightened on some of the classes of chemicals that have remained so foreign to me.

The three part series, called Six Classes, has a goal of helping consumers reduce the use of harmful chemicals by teaching us what these common chemicals are and how they affect our everyday life. It is offered free by the Green Science Policy Institute whose mission is to educate and build partnerships among scientists, regulators, businesses and public interest groups to develop innovative solutions for reducing harmful chemicals in products.

The webinars are based on what the Institute has established as six classes of harmful chemicals: highly fluorinated chemicals, antimicrobials, flame-retardants, bisphenols and phthalates, solvents and certain metals. The hour-long webinars will feature a short video on each class of chemicals (two per webinar) along with discussions with scientists and thought leaders. The webinars will share info about the toxicity of these chemicals, where they are used in our daily lives, why they are harmful and how we can avoid them.

Starting tomorrow, Thursday, June 22, and continuing the following two Thursdays, the webinars will be available three times each day. For more info and to register visit t.co/uAL2I5sb8t, or contact the Institute at 510-898-1704 or Laura@GreenSciencePolicy.org. I plan to learn a lot about toxic chemicals and green chemistry.

My dad, the chemical engineer, would be so proud of me.

Lynn Jenkins lives in rural Zionsville, where she is learning to live green. Email her at LJenks@tds.net.

Willie Geist: You could see Mika and Joe’s chemistry on-air – Page Six

Posted on by

Willie Geist says the romantic relationship that developed between his MSNBC colleaguesJoe ScarboroughandMika Brzezinski who got together in 2016 and then engaged this May was a natural progression.

You had two single people, I think they always had a good relationship, they always had good chemistry, so I was not surprised by it. I was happy for them, Geist told Andy Cohen on Mondays episode of Watch What Happens Live.

When Cohen vivaciously added that the sexual chemistry was always crackling between them, Geist wholeheartedly agreed: And on the air! On the air you saw it.

Geist said the wedding is going to be a big fancy thing and that hed be there but didnt elaborate on the pairs plans.

Geist made an appearance on the May 4 edition of Morning Joe just hours after Page Six broke the news that the couple had gotten engaged and he was a little less direct about the impending nuptials. After one panelist offered up congratulations to the couple, Geist playfully added, Numbers have been up lately. Show is going well!

Scarborough, 54, popped the question toBrzezinski in Mayduring a romantic vacation to the south of France for her 50th birthday. Mika turned 50 and realized she wanted to move forward with her life and spend every minute with Joe, and not just at work, a source close to Brzezinski dished at the time.

Page Six exclusively revealed in June 2016 that the pair was involved in a hush-hush romance after Brzezinski and her husband of more than two decades divorced. This will be twice-divorced Scarboroughs third marriage.

Chemistry defines Spokane Indians early in the season – The Spokesman-Review

Posted on by

UPDATED: Tue., June 20, 2017, 9:07 p.m.

Its still early in the season, but one trait the Spokane Indians are demonstrating is the power of chemistry. No, not the academic version of chemistry taught in high school or college, but something more like the intangible internal feeling that distinguishes a typical team from a family team.

This was seen throughout the Indians five-game season-opening home stand against Boise.

Its the kind of unique quality that brings a team together when its trailing late in a game. It comes together to use chemistry to make deficits shrink. They simply refuse to quit.

Spokane manager Matt Hagen said the teams belief in itself has been one of the things that has really stood out in the first week.

We really do have a good team chemistry, especially for the first series of the year, Hagen said.

And thats something he said will be helpful later in the summer.

At some point this season, well be getting some players in from the draft and my hope is that those guys can jump right into what we have going on already and that theyll feel right at home, he said.

Aside from the physical challenges related to the daily grind of a baseball schedule, this level of baseball can be tough from a players perspective because many of these players are not only young, but inexperienced in the rigors of professional baseball. Ten of the Indians are 20 years old or younger, giving Spokane one of the youngest teams in the Northwest League.

And none are from here. Some arent even from the United States. With players from Nevada to Nicaragua, theyre a long way from home and spending all of their days with people theyve basically just met.

Spokane infielder Kole Enright, from Florida, said thats part of what has made the team closer.

I love the guys we have from Venezuela, the Dominican Republic and from Nicaragua, he said. Were a team. Thats part of what you sign up for when youre coming into a diverse sport like baseball.

Its a closeness that was even seen during the teams opening-night game. Down 4-0 entering the sixth inning, the Indians battled and fought to tie the game in the seventh at 4-4.

After the game, several players said they knew theyd come back, even though the Indians eventually lost 5-4. They talked about bonding during earlier games in the Arizona League.

It was evident again in Sundays doubleheader.

In the first game, the Indians lost 3-1. The following game, the Spokane offense exploded for seven runs in the first inning en route to a 10-0 win.

After the game, Indians catcher Isaias Quiroz said, Were a big, energetic team. Were always on each others backs, helping each other out. Doesnt matter if were down by 10 or up by 10, were always going to have each others back. We wont let each other ever quit.

That never-say-die attitude surfaced again in Mondays final game of the series against Boise.

Heading into the seventh inning, the Indians trailed 4-1. A few hits later, the Indians tied it up and then added an eighth-inning Yohel Pozo home run.

That is when the teams character was tested again. After a leadoff single to open the ninth, Boise clubbed a potential heartbreaking ninth-inning two-run home run to put the Hawks up 6-5.

How did the Indians approach the bottom of the ninth?

With a single. Then a game-tying triple. That was followed by a single to complete the ninth-inning walk-off win over Boise, 7-6.

The players piled on each other.

Cole Ragans, starting pitcher and the Texas Rangers eighth-ranked prospect, said this group of guys already feels like a team.

Thats what were made of, he said. This is what everyone should expect of us. Most of us have played with together in the AZL so we know what to expect from each other. We like each other and were gonna come out and play like that every game down to the last pitch.

Spokane catcher Clay Middleton agreed.

We just dont give up, he said as the team celebrated around him. This is a relentless group very, very relentless. This team is never out of the fight. We believe in each other.

Students from around U.S. compete in national chemistry … – WJLA – WJLA

Posted on by

Students from across the United States competed in the "You Be the Chemist Challenge" in D.C. Monday, June 19, 2017 (Kellye Lynn, ABC7)

The future scientists were put to the test. Some of the country's best performing students competed in a national chemistry competition. Seventh grade Science teacher Barbara Ferri explained, "These kids are doing not only high school chemistry, they are doing chemistry that is above even the high school level."

Samuel Rhee is an eighth grader at Maret School in D.C. who was one of 42 participants competing in the "You Be the Chemist Challenge" at the Omni Shoreham Hotel in Northwest D.C. "I never really saw chemistry as something super interesting before but now I see you could actually do stuff with it," he remarked. Rhee and the other contestants battled it out in 10 rounds of competition.

The interactive academic challenge organized by the Chemical Educational Foundation provides the champion a $12,000 scholarship. Kai Svenson, 14, a student at Tilden Middle School in Rockville, Maryland told ABC7 News, "You see a lot of sports competitions and kids who aren't really into that, this is their big chance."

No matter the outcome, organizers say every participant leaves a winner. Avery Reese, manager of Outreach and Events with the Chemical Educational Foundation stated, "We want to make that connection for them now and show them how cool it is to know science and be a chemistry pro." Svenson continued, "It's not so much winning a prize or trophy but for me it's more. I want to become a chemist or a physicist and I want to know how much more I need to study to become that."

The competition involved students between the fifth and eighth grades.

Eighth-grader Ananthan Sadagopan, 13, of Westborough, Massachusetts, won the "You Be The Chemist Challenge."

Chemistry of sea spray particles linked for first time to formation … – Phys.Org

Posted on by

June 19, 2017 Credit: CC0 Public Domain

A team of researchers led by the University of California San Diego has identified for the first time what drives the observed differences in the chemical make-up of sea spray particles ejected from the ocean by breaking waves.

The discovery could enable researchers to better understand how ocean chemistry and physics directly influence cloud formation processes. The improved understanding could make climate models more accurate, especially since clouds are the hardest variable to portray in current simulations.

Kimberly Prather, Distinguished Chair in Atmospheric Chemistry and a faculty member in the Department of Chemistry and Biochemistry and Scripps Institution of Oceanography at UC San Diego, led the National Science Foundation-supported study. She said its key breakthrough involved showing that the drops sent airborne by breaking waves take on different chemical characteristics depending on the physical forces induced by the waves.

"It's the first time anyone has shown that drops from seawater have different composition due to the production mechanism," said Prather. "We are uncovering how ocean biology influences the physical production processes creating sea spray aerosol. Previous studies have focused on the processes involved in the physical production of sea sprays but our studies demonstrated that chemistry is at the heart of many ocean-atmosphere transfer processes that have profound impacts on the composition of our atmosphere as well as clouds and climate."

Some sea spray aerosols are "film" drops that are laden with microbes or organic material that collects on the ocean surface. They form when bubbles at the ocean surface rupture. Researchers had largely assumed that all aerosols smaller than a micron in size were of this variety. Prather and other researchers showed, however, that there are other cloud-forming particles derived from "jet" drops that are predominantly comprised of very different chemical species including sea salt, microbes, and other biological species. These new drops are ejected in the aftermath of bubbles popping.

These two types of aerosols have different capabilities for forming ice crystals in clouds, meaning that whether a cloud actually produces no precipitation, rain, or snow can be determined by the type of microbes and associated biomolecules being ejected from the ocean. More importantly, the presence of a large bloom of phytoplankton, as happens during red tide events, alters the ratio of film to jet drops, meaning biological processes can lead to profound changes in sea spray chemistry and ultimately cloud formation.

The study, "The role of jet and film drops in controlling the mixing state of submicron sea spray aerosol particles," appears June 19 in early editions of the journal Proceedings of the National Academy of Sciences.

The researchers found that jet-produced particles can make up nearly half the total number of submicron sea spray aerosols that contribute to cloud formation. To reach this conclusion, researchers induced phytoplankton blooms in natural seawater pumped into wave-generating tanks at a Scripps laboratory. The conditions mimicked those in the ocean that produce sea spray. The scientists differentiated the film from jet drops as they rose in the air above the waves by observing their different electric charges. Jet sea spray aerosols have a greater charge than film aerosols.

The findings are the latest to come from researchers at UC San Diego on one of the most mysterious frontiers of climate: how aerosols produced on land and at sea - whether sea salt, organic material, dust, or pollution particles - determine if clouds form and whether those clouds can produce precipitation. Prather, who pioneered methods to analyze the chemical composition of airborne particles, is the director of the Center for Aerosol Impacts on Chemistry of the Environment (CAICE) at UC San Diego where the work was performed. In 2013, the National Science Foundation named CAICE an NSF Center for Chemical Innovation, one of nine such centers in the United States.

Co-authors of the study represented a range of disciplines from biochemistry to marine microbiology. Scripps oceanographers Grant Deane and Dale Stokes contributed to the study and in follow-on work will attempt to see if they can determine the composition of sea surface aerosol mixes by measuring how long bubble-filled ocean whitecaps last.

Deane said the feat of the study likely could not have been achieved by any one of the researchers working alone, making it a model for how complex environmental research is done.

"It's a truly collaborative work among chemists, biologists, and physical oceanographers," Deane said. "This is the way this kind of work has to be done."

Chemistry between Phillips, Swanson leads resurgent Braves – Atlanta Journal Constitution

Posted on by

As a senior member of the team might do instinctively, Brandon Phillips took on a mentorship role during Dansby Swansons early season struggles.

Swanson hit .186 in the Braves first two months. Fans called for theshortstops demotion as the team floundered.

But entering the Giants series this week, Swansons was hitting .317 (19-for-60) in June and his success is reflected in the teams performance. The Braves have won or tied four of their five series this month.

Swansons started to relax a little bit more, Phillips said. I keep on giving him hell. Im always going to keep on playing around with him, loosen him up so he can play a little bit focused. Everybodys coming together and its a lot of fun.

At the beginning, you can say he was trying to do a little too much. He was uptight a little bit. So I just told him, You know, relax and play the game. Be like you were in high school. Just be that ATL-ien that you are and just have fun. Hes started to swing the bat a little bit better and hes playing better.

Defensively, Phillips said he and Swanson are close to where they need to be.

Were having a good time learning each other, he said. He knows where I like to have the ball thrown at me. I know where he likes it and its just one of those relationships where we grew together. We really take pride in our defense. You have two guys who take pride in their defense and they want to excel and be great. We just have a lot of fun out there turning double plays, talking. And me being the leader, I can be a great role model for him.

Braves manager Brian Snitker has noticed the pairs dynamics as well.

You play that much together, it kind of has a way of working itself out, you know, when theyre relying on each other and theyre kind of clicking a little bit, Snitker said. You do establish a rapport with that guy thats beside you. The level of trust and everything grows with the amount of time and the number of games they play together.

And their only interaction isnt just out there on the field, either. Its inside as they talk about the game and playing the game. So its good for (Swanson) to have somebody with that experience beside him.

The clubhouse is meshing, especially during its recent success, according to Phillips. He and the other vets have embraced guiding the youth movement.

Ownership did a great job getting the right guys over here, he said. We didnt have the superstars, all those guys, but the right group of guys. We all have personality. We all get along with each other. R.A. Dickey, (Bartolo) Colon, myself, Kemp; we just all get along with each other and the young guys listen to us, follow our lead. They see our work ethic Those guys come to the field hungry, earlier than I do, in fact.

The Phillips-Swanson duo has started to gain traction since Phillips was acquired from Cincinnati to plug the second base spot before spring training. Not only has Swanson regained form, but Phillips has hit .339 since May 16. He produced back-to-back walk-off singles Saturday and Sunday to give the Braves another series win over the Marlins.

Were just having fun, Phillips said. Were still getting to know each other. Were starting to put everything together. The pitching staff is doing a great job. The bullpens looking good. Were starting to get quality hits, having great at-bats and like I said, we get to .500, theres no turning back.

Entering the week, Atlanta was 25-25 over its last 50 games. Phillips admitted he thought the road-heavy April and May hurt the team.

The only thing I can say is this: The beginning of our season has been crazy, he said. I dont like making excuses, but playing on the road, Ive never, ever had a season Ive been playing baseball for a long time Ive never seen a schedule like this before, or ever at the beginning. So whoevers listening to me and whoever made the schedule, yall need to change that. No team should go through what we just (went) through.

Despite their budding friendship, Phillips said hes tired of losing rock-paper-scissors to his protege. Phillips started a celebration where the two play the finger game on the field immediately following every win.

Im not going to lie to you, hes kicking my butt so far, Phillips said. So I got to step my rock-paper-scissors game up.

Concrete Chemistry Pioneer Bill Hime is Dead at 91 – Engineering News-Record (subscription)

Posted on by

William G. "Bill" Hime, one of the nation's first and premier experts in cement chemistry and a pioneer in failure analysis of concrete and construction materials, died on June 6 in Glenview, Ill. He was 91.

The death of the former senior principal of structural and forensics engineer Wiss, Janney, Elstner Associates Inc. follows by just 10 days that of the Illinois firm's former president John M. Hanson.

Hime joined Wiss, Janney in 1984 with its acquisition of Erlin, Hime Associates, which he had co-founded 12 years earlier with Bernard Erlin. It specialized in chemical and petrographic analyses of construction materials.

The chemist had previously been a chemistry assistant professor at Louisiana Tech University, and also laboratory chief and manager of chemical and petrographic research at the Portland Cement Association.

Among other things, while at Erlin, Himes, he was widely consulted to offer analysis on the use of Sarabond as a concrete mortar additive that was linked to masonry cracking, according to a March 1986 ENR article.

Himes said the Sarabond leached out chloride ions when in contact with unprotected steel in a building, which, in turn, had accelerated corrosion. He said excessive buildup of rust pushed outward on the masonry, eventually cracking and displacing bricks.

In a 1983 article related to ongoing litigation, the New York Times said Sarabond had been used in about 2,000 buildings.

Hime published more than 100 professional articles in books and magazines and received numerous industry group awards. He remained a Wiss, Janney principal until he was 81 and "was a champion" in cement burn prevention, said the firm.

"When there was a need for analytical work, [Hime] enthusiastically beamed when he did hands-on 'wet chemistry' to get data that more [sophisticated] instrumental methods would miss, or not be as accurate," said former partner Erlin in a 2007 interview in Concrete Construction magazine, referring to him as "one of the greatest chemical and technological minds of our industry."

Green chemistry efforts honored – Chemical & Engineering News

Posted on by

The 12 Principles of Green Chemistry are a how-to guide written 20 years ago for chemists and chemical engineers. They provide insight on developing new chemicals and chemical processes and revitalizing existing ones so that they achieve their desired function while being environmentally and economically friendly. Its a creative challenge to put the 12 principles into action.

Five technologies that have succeeded in meeting that creative challenge are being recognized with 2017 Green Chemistry Challenge Awards. Merck, Dow Chemical, Koehler, Amgen, Bachem, UniEnergy Technologies, and University of Pennsylvania chemistry professor Eric J. Schelter were honored for their achievements at a ceremony held on June 12 at the National Academy of Sciences in Washington, D.C.

The Environmental Protection Agency established the Green Chemistry Challenge Awards program in 1995 as a competitive effort to promote chemical products and manufacturing processes that help the agency achieve federal goals set by the Pollution Prevention Act of 1990. The program is administered by EPAs Green Chemistry Program and is supported by partners from industry, government, academia, and other organizations, including the ACS Green Chemistry Institute.

EPA has now presented 114 of the awards to scientists and companies selected from more than 1,700 nominations. The work described in the award nominations must have been carried out or demonstrated in the U.S. in the preceding five years. An independent panel selected by ACS, which publishes C&EN, judges the nominations and selects the award winners.

Among this years winners, Merck took home the Greener Synthetic Pathways Award for developing a streamlined synthesis of the antiviral drug letermovir, which is currently in Phase III clinical trials. The new synthesis reduces the process mass intensity for making the drug, a sustainability measure of raw materials used per amount of product made, by 73% compared with the original synthesis.

Dow and papermaker Koehler jointly landed the Designing Greener Chemicals Award for a new technology that uses a polymer coating on paper to create air pockets that collapse during printing to create an image stemming from the altered refractive index of the coating. This physical process replaces chemical dyes and image developers such as bisphenol A in the production of thermal paper used for printing receipts.

Amgen and Bachem teamed up to receive the Greener Reaction Conditions Award for an improved peptide manufacturing technology to make the drug etelcalcetide, a calcium inhibitor to help control activity of the thyroid gland in patients with kidney disease. The new process produces more peptide in less time while drastically cutting solvent and water use.

UniEnergy Technologies garnered the Small Business Award for its design of a vanadium-based redox flow battery for grid-scale energy storage. The new battery has double the energy density of previous flow battery technology even though its smaller and uses smaller amounts of chemicals.

Schelter got the nod for the Academic Award for developing a process that uses tailored ligands to separate mixtures of rare-earth metals during the recycling of consumer lighting and electronics. Scientists expect the approach to reduce energy use and the waste generated during recycling of rare-earth metals and help minimize new rare-earth metal mining.

The Green Chemistry Challenge Awards highlight the importance of sustainable chemistry and its impact across a range of disciplines, says Princeton Universitys Paul J. Chirik, a 2016 award recipient. Striking features common among many of the winners is that green chemistry often results in an improved product or a cost savings, demonstrating that environmentally responsible science does not have to come with reduced performance or added cost.

The textual chemistry of young love – The Hindu

Posted on by

We occupy a world where words have become the opposite of technology. When I read a long essay or a thoughtful book, I subconsciously attribute an oldness to the author. Like charming remnants of a bygone era, theres something impossibly experienced about writing. But technology is a young beast. It turns ancient nouns into modern verbs you text someone, you dont write a text to them. You message someone, you dont compose a message to them.

Cinema has invariably punctuated this clash of communication. Love is traditionally a long-form feeling. Serious characters in dire situations write letters or, at worst, eloquent emails to each other. They accidentally discover one another through a medium of writing, before discovering one another through writing. The Lunchboxs middle-aged widower Saajan Fernandes (Irrfan Khan) and housewife Ila (Nimrat Kaur) trade thoughts through handwritten notes because fortuitous words were their first point of contact. Youve Got Mails Joe (Tom Hanks) and Kathleen (Meg Ryan) exchange emails because of their chance correspondence in an over-30s chatroom. The Lake Houses Alex (Keanu Reeves) and Kate (Sandra Bullock) exchange letters because they exist across two separate time periods. These couples thrive on connecting intellectually to connect emotionally. Their souls meet for their hearts to beat.

But even they would tut-tut at the sight of red-blooded kids typing on their cellphone screens. Texting, for an entire generation of old-school idealists, is not the language of longing its the bastardization of personal expression. This is also because the movies, as a whole, have often condescended on the shorthand of new-age interaction. Just like travel is used for visual gratification, social media is used as a flimsy cosmetic device; emojis and web slang are tonal rather than narrative tools. But Alice Wus The Half of It (on Netflix) is that rare film in which words marry technology. It puts the text back in texting: Messages read like compressed letters, while cellphones feel like motorised papers. On the face of it, The Half of It has a crowd-pleasing premise: A closeted Chinese-American student (Leah Lewis, as Ellie) is hired by an inarticulate jock (Daniel Diemer, as Paul) to write love letters for him to the popular girl (Alexxis Lemire, as Aster). Ellie gets carried away; letters soon turn into late-night texts. Geeky Ellie finds a kindred spirit a mind of melancholy and culture and loaded ellipsis in pretty Aster, who in turn thinks she has located the literature behind Pauls empty gaze.

Despite the girls tender age, theres a charming antiquity about their textual chemistry. They speak like highschoolers, but write like artists freed from the shackles of social etiquette. They simultaneously hide behind and reveal themselves through their chats. For once, a distant romance is allowed to wear the wisdom of a digital emotion. The characters may be misfits whose art of differentness is inextricably linked to loneliness, but they prefer the slow-burning subtext of the written word even in the presence of human company. A memorable scene features an awkward date between Aster and Paul being rescued by an impromptu texting session under the table. Aster feels surer once she reads Pauls (but actually Ellies) messages, perhaps bemused by the fact that the boldness of their heads aided by safeness of technology is stimulating each other more than their bodies. The Half of It is so gracious about the grammar of the young gaze that Ellies sexuality becomes a footnote. One suspects that even if she wasnt a queer immigrant in a conservative American town, Ellie might have still pursued intimacy in the stealth of automated darkness.

At one point, Aster confides in Ellie that Paul makes her feel safe in person, but his texts are bold. The dissonance of his personality is confusing. In many ways, I resonate with the duality of the plots central conceit. Owing to my social anxiety, every relationship of my adult life has started with carefully constructed words that lead to the future. A relationship has two versions of me. The online version playing out over ponderous texts and instant messaging, a faceless equation infused with the naked courage of two strangers on a liferaft. Thinking is an integral part of liking. Consequently, falling in love feels less like a leap of faith and more like a wobbly parachute of fate. We share music, opinions, secrets, tiny pieces of ourselves to see if they fit. This version is what I wish to be in person. (Aditya Chopras Rab Ne Bana Di Jodi literalised this duality).

Then theres the offline version playing out face to face, or on the phone, once the intrigue of words wears off. This is the spellbreaking reality, the clumsy part initially concealed through the confidence of writing. Its jarring, resulting in a sort of sibling-like affection to overcompensate for the daring side. The passion melts away. Life gets diluted by the film we envisioned in our head. Perhaps thats why Saajan resisted meeting Ila, and Ellie left in a train after kissing Aster. Maybe they knew all along. If words form their story, only the written half of it is love.

Chemists Discovered the Structure of a Key Influenza Protein Breakthrough Could Lead to Flu Treatment – SciTechDaily

Posted on by

A team of MIT chemists has discovered the structure of a key influenza protein, a finding that could help researchers design drugs that block the protein and prevent the virus from spreading.

The protein, known as BM2, is a proton channel that controls acidity within the virus, helping it to release its genetic material inside infected cells.

If you can block this proton channel, you have a way to inhibit influenza infection, says Mei Hong, an MIT professor of chemistry and senior author of the study. Having the atomic-resolution structure for this protein is exactly what medicinal chemists and pharmaceutical scientists need to start designing small molecules that can block it.

MIT graduate student Venkata Mandala is the lead author of the paper, which was published on February 3, 2020, in Nature Structural and Molecular Biology. Other authors include graduate students Alexander Loftis and Alexander Shcherbakov and associate professor of chemistry Bradley Pentelute.

There are three classes of influenza virus A, B, and C and each of them produces a different version of the M2 protein. M2 is an ion channel that carries protons through the viruss outer membrane, known as the lipid envelope. These protons usually flow into the virus, making the interior more acidic. This acidity helps the virus to merge its lipid envelope with the membrane of a cellular compartment called an endosome, allowing it to release its DNA into the infected cell.

Until now, most structural studies of the M2 protein have focused on the version of M2 found in influenza A, which is usually the most common form, especially earlier in the flu season. In this study, the researchers focused on the version of M2 found in influenza B viruses, which usually dominate in March and April. However, in contrast to previous patterns of seasonal flu infections, this winter, influenza B has been unusually dominant, accounting for 67 percent of all flu cases reported to the U.S. Centers for Disease Control since last September.

The A and B versions of M2 vary significantly in their amino acid sequences, so Hong and her colleagues set out to study what structural differences these proteins might have, and how those differences influence their functions. One key difference is that the BM2 channel can allow protons to flow in either direction, whereas the AM2 channel only allows protons to flow into the viral envelope.

To investigate the structure of BM2, the researchers embedded it into a lipid bilayer, similar to a cell membrane, and then used nuclear magnetic resonance (NMR) spectroscopy to analyze the structure with atomic-scale resolution. Very few ion channels have been studied at such high resolution because of the difficulty of studying proteins embedded within membranes. However, Hong has previously developed several NMR techniques that allow her to obtain accurate structural information from membrane-embedded proteins, including their orientation and the distances between atoms of the protein.

The M2 channel is made of four helices that run parallel to each other through the membrane, and Hong found that the alignment of these helices changes slightly depending on the pH of the environment outside the viral envelope. When the pH is high, the helices are tilted by about 14 degrees, and the channel is closed. When the pH goes down, the helices increase their tilt to about 20 degrees, opening up like a pair of scissors. This scissoring motion creates more space between the helices and allows more water to get into the channel.

Previous studies have found that as water flows into the M2 channel, the amino acid histidine grabs protons from the water in the top half of the channel and passes them to water molecules in the lower half of the channel, which then deliver the excess protons into the virion.

Unlike the AM2 channel, the BM2 channel has an extra histidine at the virion-facing end of the channel, which the MIT team believes to explain why protons can flow in either direction through the channel. More study is needed to determine what kind of advantage this may provide for influenza B viruses, the researchers say.

Now that chemists know the structure of both the open and closed states of the BM2 channel at atomic resolution, they can try to come up with ways to block it. There is precedent for this type of drug development: Amantadine and rimantadine, both used to treat influenza A, work by wedging themselves into the AM2 channel pore and cutting off the flow of protons. However, these drugs do not affect the BM2 channel.

Hongs research group is now investigating another one of BM2s functions, which is generating curvature in lipid membranes in order to allow progeny viruses to be released from cells. Preliminary studies suggest that a portion of the protein that sticks out from the membrane forms a structure called a beta sheet that plays a role in inducing the membrane to curve inward.
