As part of an international team of researchers, scientists at the Helmholtz Center Berlin have observed the switching mechanism from a non-conducting to a conducting state in iron oxide (specifically, magnetite) with previously unrealized precision. This switching mechanism, which in oxides proceeds in two consecutive steps, is thousands of times faster than it is in current transistors.
Could a substance that resembles baby powder curb global carbon emissions? Wake Forest University researchers believe so, and a new Department of Energy grant worth more than $1 million will enable them and collaborators at the University of Texas at Dallas to design a novel material that could help revolutionize green engineering.
The American National Standards Institute Nanotechnology Standards Panel (ANSI-NSP) announces the launch of a new database compiling information about nanotechnology-related standards and affiliated activities.
Nearly doubling the efficiency of a breakthrough photovoltaic cell they created last year, UCLA researchers have developed a two-layer, see-through solar film that could be placed on windows, sunroofs, smartphone displays and other surfaces to harvest energy from the sun.
Engineers at the California Institute of Technology have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope
Researchers at the University of Central Florida have developed a technique to increase the energy storage capabilities of supercapacitors, essential devices for powering high-speed trains, electric cars, and the emergency doors of the Airbus A380.
Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. Researchers have developed an advanced opto-mechanical sensing technique based on tetrapod quantum dots that allows precise measurement of the tensile strength of polymer fibers with minimal impact on the fiber's mechanical properties.
A team of theoretical physicists at the U.S. Naval Research Laboratory (NRL) and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date.
