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
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 ...
Study Yields Surprising New Insight into High-Temp Superconductors
Speed limit on a superfluid helium nano-highway
Scientists from the University of Amsterdam (UvA), the Ecole Polytechnique Fédérale de Lausanne (EPFL) and the Universitat de Barcelona have been able to determine the so-called Landau velocity for helium ...
Researchers develop nanodiamond thermometer to take temperature of individual cells
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 ...
The ferromagnetic Kondo effect
A group of physicists that includes scientists of the International School for Advanced Studies (SISSA) of Trieste have shown how to obtain a particular case of a physical effect – so far never observed ...
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.
Phase transition may explain how brain neurons encode information
Platinum is wrong stuff for fuel cells as it wastes energy, researcher suggests
Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the ...
Research pushes the boundaries of electron microscopy to unlock the potential of graphene
(Phys.org)—Electron microscopy at the Department of Energy's Oak Ridge National Laboratory is providing unprecedented views of the individual atoms in graphene, offering scientists a chance to unlock the ...
Extrusion for greener aluminum production
Aluminum recycling has become a successful business since its inception a century ago. Nearly a third of the aluminum produced in the United States is made from aluminum scraps that have been recycled in ...
Nanophysicists find unexpected magnetic effect: Kondo effect noted in single-atom contacts of pure ferromagnets
Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts that are just one atom wide.
