A new study presents evidence for a long-sought phenomenon - first theorized in the 1960s and predicted to be found in crystals in 1983 - called the 'chiral anomaly' in a metallic compound of sodium and bismuth. The additional finding of an increase in conductivity in the material may suggest ways to improve electrical conductance and minimize energy consumption in future electronic devices.
A new could offer a simple way to improve the efficiency of electronic devices such as light-emitting diodes, optical fibers and solar cells. It also could have important theoretical implications for understanding the still surprisingly mysterious materials called glasses.
We invariably imagine electronic devices to be made from silicon chips, with which computers store and process information as binary digits (zeros and ones) represented by tiny electrical charges. But it need not be this way: among the alternatives to silicon are organic mediums such as DNA.
The Lloyd's Register Foundation has awarded grants totalling GBP 9 million to three international consortia in the field of nanotechnology. These grants support research and doctoral training that will support the Foundation's aims to advance engineering-related education and research and support work that enhances safety of life at sea, on land and in the air.
Researchers have shown that a new device concept - a 'squishy' transistor - can overcome the predicted power bottleneck caused by CMOS (complementary metal-oxide-semiconductor) technology reaching its fundamental limits.
It has long been accepted that such a thin layer of lubrication between sliding surfaces alternates along with the cycles of sticking and slipping; it starts as a solid, turns to liquid in the slipping phase and then back to a solid when the surfaces stick once again. But a recent paper suggests this model is incorrect.
