If one side of a conducting or semiconducting material is heated while the other remains cool, charge carriers move from the hot side to the cold side, generating an electrical voltage known as ...

Michael Strano (Massachusetts Institute of Technology) laboratory has been interested in how carbon nanotubes can be utilized to illustrate new concepts in molecular and energy transfer. In the first ...

Scientists have discovered a new relation among electric and magnetic fields and differences in temperature, which can result in swirling vortices of electrons and holes in semiconductor devices and ...

Researchers from Massachusetts have found a way to store energy in thin carbon nanotubes by adding fuel along the length of the tube, chemical energy, which can later be turned into electricity by ...

(Nanowerk News) Berkeley Lab scientists and their colleagues have discovered a new relation among electric and magnetic fields and differences in temperature, which may lead to more efficient ...

Thermoelectric materials convert heat into electricity, and their effectiveness is largely determined by their thermopower, which reflects how charge carriers respond to their environment. Designing ...

Thermoelectric materials have the ability to generate electricity when a temperature difference is applied to them. Conversely, they can also generate a temperature gradient when current is applied to ...

Researchers in the US and Korea have discovered that igniting a carbon nanotube, coated in chemically flammable material, can trigger a high-speed wave to race along the tube at 10,000× the speed of ...

A paper published in Nature Materials this week details a new method for using nanotubes to generate significant amounts of power, at least for their size. When multi-walled carbon nanotubes are ...
