New studies explain insulator-to-metal transition of vanadium dioxide
When heated to just above room temperature, the electrical conductivity of vanadium dioxide (VO2) abruptly increases by a factor of 10,000. Experiments coupled with high-performance computation reveal how ...

Mechanical motion rectifier leads to better energy harvesting
Scientists discover new water waves
Trains’ vibrations could provide power for monitoring tunnels
MIT finger device reads to the blind in real time
Scientists at the Massachusetts Institute of Technology are developing an audio reading device to be worn on the index finger of people whose vision is impaired, giving them affordable and immediate access ...
Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...
Good vibrations give electrons excitations that rock an insulator to go metallic
For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize-winning ...
Vehicle shock absorber recovers energy from bumps in the road
The symphony of life, revealed: New imaging technique captures vibrations of proteins
Like the strings on a violin or the pipes of an organ, the proteins in the human body vibrate in different patterns, scientists have long suspected.
Diamond imperfections pave the way to technology gold
(Phys.org) —From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in ...
New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
Researchers 'detune' a molecule: Experiment shows how to soften atomic bonds in a buckyball
(Phys.org) —Rice University scientists have found they can control the bonds between atoms in a molecule.
