Superconductors – metals in which electricity flows without resistance – hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical ...
Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established ...

The concept of “valence” – the ability of a particular atom to combine with other atoms by exchanging electrons – is one of the cornerstones of modern chemistry and solid-state physics.Valence control...
If they’re quick about it, “hot” electrons excited in a plasmonic metal can tunnel their way across a nanoscale gap to a neighboring metal. Rice University scientists said the cool part is what happen...

Common sense might dictate that for an object to move from one point to another, it must go through all the points on the path.“Imagine someone driving from Kansas City to Topeka on I-70 — it’s safe t...

UNIVERSITY PARK, Pa. -- Current computing is based on binary logic -- zeroes and ones -- also called Boolean computing, but a new type of computing architecture stores information in the frequencies a...
HOUSTON – (Jan. 30, 2014) – Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly...
Physicists have used holography to reliably do to electrons what they can already do to photons – twist the particle wavefronts to create beams with vortices at their centre. The researchers say that ...
Researchers in Germany and the US have used flashes of laser light to follow the motion of valence electrons as they are excited and ejected from atoms of krypton. They say that their technique could ...
An exotic type of symmetry - suggested by string theory and theories of high-energy particle physics, and also conjectured for electrons in solids under certain conditions - has been observed experime...
The recent winners of this year's Nobel Prize for Chemistry join a famous lineage of scientists who have shed light on the biomolecular world by using X-ray crystallography. However, new research publ...
As well as producing spectacular lightning shows, thunderclouds can also sometimes emit strange long-lasting bursts of gamma rays. Now, a group of researchers in Japan claims to have the best evidence...
