(Phys.org) —How does consciousness work? Few questions if any could be more profound. One thing we do know about it, jokes biophysicist Luca Turin, is that it is soluble in chloroform. When you put the brain into chloroform, ...
A team of researchers from IBM Research Europe, Universidade de Santiago de Compostela and the University of Regensburg has changed the bonds between the atoms in a single molecule for the first time. In their paper published ...
The hissing sound you hear in the background when you turn up the volume of your music player is called "noise". Most of this hiss is due to the thermal motion of electrons in the music-player circuitry. Just like molecules ...

(PhysOrg.com) -- Detecting the coherent motion of a single electron is a challenge, for the simple reason of scale: the timescale of the coherent motion of a single-electron wave function is in the picosecond regime (one ...
(Phys.org)—A new graphene-based transistor in which electrons travel both over a barrier and under it (by tunneling) has exhibited one of the highest performances of graphene-based transistors to date. The combination of ...
Researchers from the National Institute of Advanced Industrial Science and Technology (AIST) have demonstrated the operation of a synthetic electric field tunnel field-effect transistor with a new architecture.
