New technology using silver may hold key to electronics advances
Engineers at Oregon State University have invented a way to fabricate silver, a highly conductive metal, for printed electronics that are produced at room temperature.
Trapping vortices key to high-current superconductors
If we are to see the promised benefits of high-temperature superconductors, such as low-loss motors and generators or maglev trains, we will need superconductors that can carry very large currents.

Superconductivity without cooling
Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for example ...
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.
High-Tc superconductivity found under high pressure
Drastic enhancement of superconducting transition temperature (Tc) can be induced by placing materials under high pressure, state Yoshihiro Kubozono and his team at Okayama University.
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, ...
Simulating superconducting materials with ultracold atoms (w/ Video)
Using ultracold atoms as a stand-in for electrons, a Rice University-based team of physicists has simulated superconducting materials and made headway on a problem that's vexed physicists for nearly three ...
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 ...
