Researchers have succeeded in producing a coating material that can be written on using UV light and the writing erased again using oxygen. Changes to rewritable paper could help reduce paper waste in a wide variety of applications. ...
Over the past few years, many physicists and material scientists have been investigating superconductivity, the complete disappearance of electrical resistance observed in some solid materials. Superconductivity has so far ...
Can you imagine charging your mobile phone by simply using your body heat? It may still sound rather futuristic, but thermoelectrics can do it. Thermoelectrics is all about transforming heat into useful energy, mostly using ...
Flashing graphene into existence from waste was merely a good start. Now Rice University researchers are customizing it.
Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers—materials composed of molecular ...
The quest for thermoelectric materials that efficiently convert changes in temperature into electric voltage is challenging. For optimal performance, a material must conduct small amounts of heat and large amounts of electricity. ...
A University of Melbourne-led team has perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given ...
Researchers at Institute for Molecular Science, and University of Toyama, in Japan, report an efficient organic light emitting diode (OLED) operable by a 1.5-V battery that produces bright emission equivalent to luminance ...
Ever since graphene—a thin carbon sheet just one-atom thick—was discovered more than 15 years ago, the wonder material became a workhorse in materials science research. From this body of work, other researchers learned ...
In recent years, electronics engineers have been trying to broaden the pool of available semiconducting materials, to enable the development of a wider range of devices. One emerging class of semiconductors are amorphous ...
