Physicists propose explanation for metals behaving badly
Molten-air battery's storage capacity among the highest of any battery type
Study explains atomic action in high-temperature superconductors
A study at the Department of Energy's SLAC National Accelerator Laboratory suggests for the first time how scientists might deliberately engineer superconductors that work at higher temperatures.
A quick look at electron-boson coupling: Researchers use ultrafast spectroscopy on many body effects
Imagine being able to tune the properties of a solid material just by flashing pulses of light on it, for example turning an insulator into a superconductor. That is just one potential payoff down-the-road ...
How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
When an exciton acts like a hole
(Phys.org) —When is an electron hole like a quasiparticle (QP)? More specifically, what happens when a single electron hole is doped into a two-dimensional quantum antiferromagnet? Quasiparticle phenomena ...
Cambridge team breaks superconductor world record
A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample ...
Superconducting secrets solved after 30 years
(Phys.org) —A breakthrough has been made in identifying the origin of superconductivity in high-temperature superconductors, which has puzzled researchers for the past three decades.
Solving a mystery of thermoelectrics
Materials that can be used for thermoelectric devices—those that turn a temperature difference into an electric voltage—have been known for decades. But until now there has been no good explanation for ...
Scientists watch high-temperature superconductivity emerge out of magnetism
(Phys.org) —Scientists at SLAC National Accelerator Laboratory and Stanford University have shown for the first time how high-temperature superconductivity emerges out of magnetism in an iron pnictide, ...
Your T-shirt's ringing: Telecommunications in the spaser age
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
Phase transiting to a new quantum universe
(Phys.org) —Recent insight and discovery of a new class of quantum transition opens the way for a whole new subfield of materials physics and quantum technologies.
High-temperature plasmonics eyed for solar, computer innovation
(Phys.org) —New "plasmonic metamaterials" that operate at high temperatures could radically improve solar cell performance and bring advanced computer data storage technology that uses heat to record information ...
