Chemists at Vanderbilt University have created a new class of liquid crystals with unique electrical properties that could improve the performance of digital displays used on everything from digital watches to flat panel televisions.
Optical gyroscopes, also known as rotation sensors, are widely used as a navigational tool in vehicles from ships to airplanes, measuring the rotation rates of a vehicle on three axes to evaluate its exact position and orientation. Prof. Koby Scheuer of Tel Aviv University's School of Physical Engineering is now scaling down this crucial sensing technology for use in smartphones, medical equipment and more futuristic technologies.
Traditional x-ray photoelectron spectroscopy (XPS) works only in a vacuum, while fuel cells need gases under pressure to function. Now a team of scientists from the University of Maryland, the U.S. Department of Energy's Sandia National Laboratories, and DOE's Lawrence Berkeley National Laboratory has used a new kind of XPS, called ambient-pressure XPS (APXPS), to examine every feature of a working solid oxide electrochemical cell.
Researchers at the Georgia Institute of Technology have developed a new 'templated growth' technique for fabricating nanometer-scale graphene devices. The method addresses what had been a significant obstacle to the use of this promising material in future generations of high-performance electronic devices.
The 2007 landmark article in Nature Materials "The rise of graphene" by the just announced winners of the 2010 Nobel prize in physics, Andre Geim and Kosta Novoselov, has now been made available as a free access article.
The American Chemical Society (ACS) will honor the discovery of fullerenes, the scientific achievement that gave birth to nanotechnology, as a National Historic Chemical Landmark in a ceremony to be held at Rice University in Houston, Texas, on Oct. 11.
Two teams of researchers from China and France report success in making and testing tiny high-frequency capacitors made from a complex manmade mineral: barium strontium titanate (BST). By introducing an ultrathin (1.2 nanometer) titanium oxide seed layer, the researchers made thin BST films that exhibited excellent microwave properties up to 40 GHz.
Two Case Western Reserve University researchers are building implants made of diamond and flexible polymer that are designed to identify chemical and electrical changes in the brain of patients suffering from neural disease, or to stimulate nerves and restore movement in the paralyzed.
A prototype device developed in Hong Kong will allow laboratory researchers to non-invasively test drugs for their ability to kill tumors by subjecting cancerous cells with different concentration gradients.
An important step - one that is essential to the ultimate construction of a quantum computer - was taken for the first time by physicists at UC Santa Barbara. The research involves the entanglement of three quantum bits of information, or qubits. Before now, entanglement research in the solid state has only been developed with two qubits.
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2010 to Andre Geim and Konstantin Novoselov, University of Manchester, 'for groundbreaking experiments regarding the two-dimensional material graphene'.
