UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors - devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom-thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.
Using chemical imaging techniques, scientists at Pacific Northwest National Laboratory proved for the first time that titanium dioxide's surface defects shelter chemicals from decays caused by ultra-violet light. The defects are tiny gaps created when oxygen atoms are missing from the surface of this popular catalyst.
A Johns Hopkins engineer who is designing cancer-fighting nano-size structures that could assemble themselves and deliver treatment to diseased tissue has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation.
Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are now presenting the missing piece.
Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a "nano-shish-kebab," consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire.
Manufacturers' inability to introduce strained silicon into flexible electronics has limited their theoretical speed and power to, at most, approximately 15 gigahertz. Thanks to a new production process being pioneered by University of Wisconsin-Madison engineers, that cap could be lifted.
When someone claims he has seen a ghost, the phenomenon may be caused by an optical illusion happening through a wild stroke of nature. But the actual engineering of such a phenomenon is the holy grail of researchers in the field of optical illusions, electromagnetic, and radar detection - not only because of the thrill and excitement of being able to create a "ghost" but because of the implications it will have in science and applications.
For the first time, researchers have designed a special material interface that has been shown to add to and to improve the functioning of non-silicon-based electronic devices, such as those used in certain kinds of random access memory (RAM).
Currently, there are 285 companies in California involved in nanotechnology-related business activities. In addition, there are 111 nanotechnology and nanoscience-related research and community organizations in California. There are 8 academic nanotechnology degree programs in California.
Two Rutgers physics professors have proposed an explanation for a new type of order, or symmetry, in an exotic material made with uranium - a theory that may one day lead to enhanced computer displays and data storage systems and more powerful superconducting magnets for medical imaging and levitating high-speed trains.
Lockheed Martin and Singapore's Nanyang Technological University (NTU) today announced a memorandum of understanding (MOU) to explore the science of nanotechnology, with special focus on nanocopper and related technologies for the commercial market.
For the first time, researchers from CNRS and the Université d'Orléans have explored the molecular rearrangements at play in commercially available supercapacitors while in operation. The technique devised by the scientists provides a new tool for optimizing and improving tomorrow's supercapacitors.
