Researchers have developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened.
A bright blue pigment used 5,000 years ago is giving modern scientists clues toward the development of new nanomaterials with potential uses in state-of-the-art medical imaging devices, remote controls for televisions, security inks and other technology.
Electrodes operated into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal.
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.
