How would electrons behave if confined to a wire so slender they could pass through it only in single-file?
The question has intrigued scientists for more than half a century. In 1950, Japanese Nobel Prize winner Sin-Itiro Tomonaga, followed by American physicist Joaquin Mazdak Luttinger in 1963, came up with a mathematical model showing that the effects of one particle on all others in a one-dimensional line would be much greater than in two- or three-dimensional spaces. Among quantum physicists, this model came to be known as the "Luttinger liquid" state.
Until very recently, however, there had been only a few successful attempts to test the model in devices similar to those in computers, because of the engineering complexity involved. Now, scientists from McGill University and Sandia National Laboratories have succeeded in conducting a new experiment that supports the existence of the long-sought-after Luttinger liquid state. Their findings, published in the Jan. 23 issue of Science Express, validate important predictions of the Luttinger liquid model.
The experiment was led by McGill PhD student Dominique Laroche under the supervision of Professor Guillaume Gervais of McGill's Department of Physics and Dr. Michael Lilly of Sandia National Laboratories in Albuquerque, N.M. The new study follows on the team's discovery in 2011 of a way to engineer one of the world's smallest electronic circuits, formed by two wires separated by only about 15 nanometers, or roughly 150 atoms.
What does one-dimensional quantum physics involve? Gervais explains it this way: "Imagine that you are driving on a highway and the traffic is not too dense. If a car stops in front of you, you can get around it by passing to the left or right. That's two-dimensional physics. But if you enter a tunnel with a single lane and a car stops, all the other cars behind it must slam on the brakes. That's the essence of the Luttinger liquid effect. The way electrons behave in the Luttinger state is entirely different because they all become coupled to one another."
To scientists, "what is so fascinating and elegant about quantum physics in one dimension is that the solutions are mathematically exact," Gervais adds. "In most other cases, the solutions are only approximate."
Making a device with the correct parameters to conduct the experiment was no simple task, however, despite the team's 2011 discovery of a way to do so. It took years of trial, and more than 250 faulty devices each of which required 29 processing steps before Laroche's painstaking efforts succeeded in producing functional devices yielding reliable data. "So many things could go wrong during the fabrication process that troubleshooting the failed devices felt like educated guesswork at times," explains Laroche. "Adding in the inherent failure rate compounded at each processing step made the fabrication of these devices extremely challenging."

[ Watch the Video: Cats Inspire Nanotechnology Whiskers For Robotics ]
April Flowers for redOrbit.com Your Universe Online
Nanotechnology has brought us many advances such as electronic skin (e-skin) and electronic eye implants (e-eyes), and now, a research team from Berkeley Lab and the University of California Berkeley is on the verge of creating electronic whiskers.
The study, published in Proceedings of the National Academy of Sciences, describes the tactile sensors the team has created from composite films of carbon nanotubes and silver nanoparticles similar to the highly sensitive whiskers of cats and rats. The pressure of a single Pascal equivalent to the pressure exerted on a table surface by a dollar bill can be felt by the new e-whiskers. The researchers see many potential applications, including giving robots new abilities to see and feel their surrounding environment.
Whiskers are hair-like tactile sensors used by certain mammals and insects to monitor wind and navigate around obstacles in tight spaces, Ali Javey, a faculty scientist in Berkeley Labs Materials Sciences Division and a UC Berkeley professor of electrical engineering and computer science, told Berkeley Labs Lynn Yarris. Our electronic whiskers consist of high-aspect-ratio elastic fibers coated with conductive composite films of nanotubes and nanoparticles. In tests, these whiskers were 10 times more sensitive to pressure than all previously reported capacitive or resistive pressure sensors.
Javey and his team are leaders in the electronic skin development, along with other flexible electronic devices that interface with the environment. In making the whiskers, the team used a carbon nanotube paste to form an electrically conductive network matrix. This was loaded with a thin film of silver nanoparticles that endowed the matrix with high sensitivity to mechanical strain.
The strain sensitivity and electrical resistivity of our composite film is readily tuned by changing the composition ratio of the carbon nanotubes and the silver nanoparticles, Javey said in a statement. The composite can then be painted or printed onto high-aspect-ratio elastic fibers to form e-whiskers that can be integrated with different user-interactive systems.
According to Javey, using elastic fibers with a small spring constant as the structural component of the whiskers provided large deflection. This caused high strain in response to the smallest applied pressures. To demonstrate proof-of-concept, the research team successfully used their e-whiskers to create highly accurate 2D and 3D mapping of wind flow. E-whiskers could be used in the future to mediate tactile sensing for the spatial mapping of nearby objects. This could also lead to wearable sensors for measuring heartbeat and pulse rate.
Our e-whiskers represent a new type of highly responsive tactile sensor networks for real time monitoring of environmental effects, Javey said. The ease of fabrication, light weight and excellent performance of our e-whiskers should have a wide range of applications for advanced robotics, human-machine user interfaces, and biological applications.

A UT Arlington engineering professor has proven that the effect of mass is important, can be measured and has a significant impact on any calculations and measurements at the sub-micrometer scale.
The findings help to better understand movement of nano-sized objects in fluid environments that can be characterized by a low Reynolds number, which often occurs in biological systems. The unconventional results are consistent with Newton's Second Law of Motion, a well-established law of physics, and imply that mass should be included in the dynamic model of these nano-systems. The most widely accepted models omit mass at that scale.
Alan Bowling, an assistant professor of mechanical and aerospace engineering, collaborated with Samarendra Mohanty, an assistant physics professor, and doctoral students Mahdi Haghshenas-Jaryani, Bryan Black and Sarvenaz Ghaffari, as well as graduate student James Drake to make the discovery.
A key advantage of the new model is that it can be used to build computer simulations of nano-sized objects that have drastically reduced run times as compared to a conventional model based on Newton's second law. These conventional models have run times of days, weeks, months and years while the new model requires only seconds or minutes to run.
In the past, researchers attempted to address the long run time by omitting the mass terms in the model. This resulted in faster run times but, paradoxically, violated Newton's second law upon which the conventional model was based. The remedy for this paradox was to argue that mass was unimportant at the nano-scale.
However, the new model retains mass, and predicts unexpected motion of nano-sized objects in a fluid that has been experimentally observed. The new model also runs much faster than both the conventional and massless models.
It is expected that this new model will significantly accelerate research involving small-scale phenomena.

Researcher proves mass important at nano-scale, matters in calculations and measurements
All Jeremy and Adrian Moore want is the official police report documenting their infant daughter Izabellas death just over a year ago in an unlicensed home day care in rural Perry County.
The parents say the report would help them put together the missing pieces in a death they think wasnt fully investigated and could have been prevented.
But the Perry County Sheriffs Department and a local prosecutor have so far withheld the police incident report, as well as other police reports and the recording of the 911 call made after Izzy Moore was found not breathing.
Last year, Perry County Prosecutor Tom Hoeh had the records sealed by a circuit court judge. The Moores, who have been pursuing the reports for nearly 10 months, say they have never been given a reason why they have been withheld.
The parents, who are pursuing a wrongful death suit against the providers, have had to petition the courts to obtain the investigative documents. Earlier this month, a Cape Girardeau judge issued such an order, but officials have yet to comply. The Moores attorney expects to receive the documents soon. But in the meantime, the parents must wait.
Their inability to obtain the records points to what many regard as flaws in the investigation of child deaths particularly those occurring as children sleep in Missouris unlicensed home-based child cares.
In the Moores case, Izzy was deemed by the Perry County coroner to have died on Jan. 18, 2013, of Sudden Infant Death Syndrome. Records show that when Izzy died, she was in the care of Shawna Huber, who was tending to 14 children in her home that day without a required state license. Records that the Moores have obtained suggest the child was left to nap unattended for several hours in the basement.
Police have not charged Huber with any criminal action, nor said she was a suspect in any way regarding Izzys death. Emails between the Moores and a representative of the state Childrens Division show the local sheriffs department reported the death as nonabusive and non-neglectful. That report essentially barred the Childrens Division from doing its own investigation of Huber.
Huber, reached by phone, said she had been advised by an attorney not to comment because of litigation against her by the Moores.
So the Moores, who have not spoken with Huber since Izzy died, have continued piecing together scraps of public information about their daughters death.

TAMPA Doctors have concluded that Joshua Hakken isnt fit to stand trial on charges he and his wife, Sharyn, abducted their children and fled with them to Cuba last April.
Circuit Judge Chet Tharpe said during a bench conference in court Wednesday that experts agree Joshua Hakken is insane. The judge expects to decide where to send him for treatment by March 4. At that time, Tharpe said he expects to receive a report on Sharyn Hakken. For now, the judge is deciding whether to commence a trial for Sharyn Hakken without her husband.
The couple were scheduled to go on trial Monday, but that has been put off.
Authorities said the Hakkens kidnapped their young sons from Sharyn Hakkens parents in North Tampa after they lost custody of them following run-ins with police in Louisiana. The Hakkens sailed out of Madiera Beach to Cuba, were apprehended by U.S. authorities and sent back to Tampa.
Investigation documents released in the case in September showed that friends of the couple regarded them as paranoid and delusional even before the alleged abductions.
The documents painted a picture of a disturbed couple who had latched onto grandiose antigovernment, apocalyptic ideas with conflicting political beliefs.
For example, Joshua Hakkens best friend, Stephen Joseph Morris, described Haaken as delusional and said Joshua Hakken believed the red-light cameras in Tampa were watching him and had plotted out where all the cameras were.
And Joshua Hakken believed the Air Force was using chem trails of aircraft to lace the sky to control people, according Jameson B. Rabbitt, who knew Joshua Hakken from when they both attended the University of South Florida. A mechanical engineer with a specialty in heating, ventilation and air conditioning, Hakken built an elaborate filtration system in his house to filter out the chemicals the Air Force was putting in the air, Rabbitt said.
Also, Dorothea Moores, the mother of one of Joshua Hakkens former Air Force Academy classmates, said she saw the Hakkens when they showed up at her home in Colorado a few months before the alleged abduction. She told investigators Joshua Hakken, who washed out at the academy, seemed paranoid and spoke at length about how people were chasing him and his wife. Another witness whose name is blacked out in documents told investigators the Hakkens had been living at the Land of Pines Campground in Louisiana and spoke about heading to Arizona for Armageddon. They were followers of fantasy author Terry Goodkind and spoke of Temple of Winds on the west coast and going to the Valley of Rahaan.
A bail bondsman who posted bail for Joshua Hakken in Louisiana told the Florida Department of Law Enforcement that Hakken was a nut, according to a report contained in the evidence materials.

Exposing adolescent rats to THC (tetrahydrocannabinol) the primary psychoactive ingredient in marijuanacan lead to molecular and behavioral alterations in the next generation of offspring, even though progeny were not directly exposed to the drug, researchers at the Icahn School of Medicine at Mount Sinai have found.
Male offspring showed stronger motivation to self-administer heroin during their adulthood and molecular changes in the glutamatergic system, which is the most important excitatory pathway for neurotransmission in the brain. Damage in the glutamate pathway, which regulates synaptic plasticity, has been linked to disturbances in goal-directed behavior and habit formation.
The study is published online January 22 in Neuropsy-chopharmacology.
Our study emphasizes that cannabis (marijuana) affects not just those exposed, but has adverse affects on future generations, said Yasmin Hurd, PhD, the studys senior author, and professor of psychiatry and neuroscience at the Icahn School of Medicine at Mount Sinai. Finding increased vulnerability to drug addiction and compulsive behavior in generations not directly exposed is an important consideration for legislators considering legalizing marijuana.
In the study, Dr. Hurd and colleagues gave adolescent male rats 1.5 mg/kg of THC, similar to about one joint in human use. None of the rats had been exposed to THC before, but their parents were exposed to THC as teens and then mated later in life. THC-exposed offspring worked harder to self-administer heroin by pressing a lever multiple times to get heroin infusion.
Although marijuana use and safety tends to be discussed in terms of its impact to the individual during the lifetime, few studies have addressed adverse effects in future generations. What this opens up are many questions regarding the epigenetic mechanisms that mediate cross-generational brain effects, said Dr. Hurd.

LOS ANGELES
In the corner of YouTube star Grace Helbigs bungalow on a hillside in East Los Angeles, a camera sits on a tripod waiting to be turned on.
Its a high-level Canon 60D with a flattering lens, a step up from the built-in webcam of Helbigs Mac that she used for her videos in the early years. When she records here, the lens faces down so that she has to look up at it, like a peephole. She has also shot videos on floors and on couches and standing in hotel elevators. Really, she says, a video can happen anywhere.
On a typically warm, sunny afternoon last week, she sits down at her desk and presses record, then waves her arms around.
Now were in a Grace video! she says in the same lilting, half-asleep tone thats become her hallmark delivery. Yay, videos!
Sometimes Helbig, 28, surprisingly tall and often laughing, uses professional lights to record, but they had been left at her friend and fellow YouTube personality Mamrie Harts place, so she has been shooting in the natural light coming in through her window. She also owns a high-quality microphone but hasnt been using that recently either.
Ive just been using the camera mike, she says. I guess people dont seem to mind.
No, they dont mind. In fact, Helbigs fans predominantly teenagers, mostly girls probably wouldnt care if she recorded her videos on a camcorder from 1986; they just want to hang out with her. She sees herself as an awkward older sister to her fans, she says, one who just wants to tell them about the world, even though she has no idea herself.
In the next six months shell see how far her fans are willing to follow their awkward big sis as she sets out on a variety of new ventures, including a risky split from her longtime Internet home, My Damn Channel, a potential pilot for the E! Network, a book and a film.
Helbig is trying to make the leap from YouTube popularity to international brand a trajectory she admits is a primary goal and shes banking on her young fans to propel her there.
