Polish team claims leap for wonder material graphene
It's billed as the wonder material of the 21st century with the power to revolutionise micro-electronics, and won its pioneers the 2010 Nobel Physics Prize.
Superheated Bose-Einstein condensate exists above critical temperature
Study Yields Surprising New Insight into High-Temp Superconductors
Korean researchers use graphene to create transparent loudspeakers
Close look at iron-based superconductor advances theory
(Phys.org)—Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported ...
Tokamak experiments come clean about impurity transport
A fusion reactor operates best when the hot plasma inside it consists only of fusion fuel (hydrogen's heavy isotopes, deuterium and tritium), much as a car runs best with a clean engine. But fusion fuel reactions ...
'Unzipped' carbon nanotubes could help energize fuel cells, batteries
Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at ...
Hybrid solar system makes rooftop hydrogen
While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's ...
Phase transition may explain how brain neurons encode information
Silver sheds light on superconductor secrets
(Phys.org)—By doping a bismuth-based layered material with silver, Chinese scientists demonstrated that superconductivity is intrinsic to the new material rather than stemming from its impurities.
Disorder is key to nanotube mystery
Scientists often find strange and unexpected things when they look at materials at the nanoscale -- the level of single atoms and molecules. This holds true even for the most common materials, such as water.
Disorderly conduct: Probing the role of disorder in quantum coherence
A new experiment conducted at the Joint Quantum Institute (JQI) examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections ...
New test could help track down and prosecute terrorists who use nerve gas and other agents
Scientists are reporting development of a first-of-its-kind technology that could help law enforcement officials trace the residues from terrorist attacks involving nerve gas and other chemical agents back ...
I-mode powers up on alcator C-mod tokamak
A key challenge in producing fusion energy is confining the plasma long enough for the ionized hydrogen to fuse and produce net power. Suppressing plasma turbulence is one approach to this, but the resulting ...
