Sentences with phrase «good electrical conductivity»

Less than two years ago, Kanatzidis and his team, with postdoctoral fellow Lidong Zhao as protagonist, identified tin selenide as a surprisingly good thermoelectric material; it is a poor conductor of heat (much like wood)-- a desirable property for a thermoelectric — while maintaining good electrical conductivity.

Not exact matches

Scientists initially used metal oxides as asymmetric supercapacitor electrodes, but, as metal oxides do not have particularly high electrical conductivities and become unstable over long operating cycles, it was clear that a better alternative was needed.

Since graphene was experimentally discovered in 2004, it has been the focus of vigorous applied research due to its outstanding properties such as high specific surface area, good thermal and electrical conductivities, and many more properties.

The heart of the device is a microscopic sandwich of quantum wells — crystalline films of semiconductors only a few billionths of a meter thick, each with a different electrical conductivity.

Rice materials scientist Rouzbeh Shahsavari and alumnus Navid Sakhavand first built atom - level computer models of pillared graphene — sheets of graphene connected by covalently bonded carbon nanotubes — to discover their strength and electrical properties as well as their thermal conductivity.

The process makes electrical conductivity more than a thousand times better.

Hence, the research team recognized this need for a good anode material that could offer high electrical conductivity and theoretical capacity.

Nanotubes are stronger than steel and smaller than any element of silicon - based electronics — the ubiquitous component of today's electrical devices — and have better conductivity, which means they can potentially process information faster while using less energy.

One good example is electrical conductivity.

To measure the amount of salt in seawater, for instance, they might measure how well the solution conducts electricity, since the higher the level of dissolved salt, the higher the electrical conductivity of the water.

These hybrids have advantageous combination of properties, such as biocompatibility, high tensile strength and thermal conductivity as well as superb chemical stability and electrical insulation.
