'Superstructured' solar cells achieve record efficiency of 10.9%
New laser technology could divert lightning strikes
(Phys.org) —Optical scientists at the University of Arizona and the University of Central Florida have developed a technology capable of sending high-intensity laser beams through the atmosphere much farther ...
On-chip topological light: First measurements of transmission and delay
Topological transport of light is the photonic analog of topological electron flow in certain semiconductors. In the electron case, the current flows around the edge of the material but not through the bulk. ...
New evidence to aid search for charge 'stripes' in superconductors
(Phys.org) —Scientists at the DOE's Brookhaven National Laboratory have identified a series of clues that particular arrangements of electrical charges known as "stripes" may play a role in superconductivity-the ...
Superconductor 'flaws' could be key to its abilities
(Phys.org)—Many researchers studying superconductivity strive to create a clean, pure, perfect sample, but a team of physicists found that some flaws might hold the key to a material's unique abilities.
Imaging electron pairing in a simple magnetic superconductor
In the search for understanding how some magnetic materials can be transformed to carry electric current with no energy loss, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, ...
Calorie-burning vest makes use of cold exposure
Improving the efficiency of solar energy cells
University of Adelaide chemistry researchers are studying energy loss at the molecular level of new 'plastic' materials as a step towards the development of highly efficient, low-cost and flexible solar energy cells.
Another step toward understanding of high-temperature superconductivity
(Phys.org) —Superconductors can radically change energy management as we know it, but most are commercially unusable because they only work close to absolute zero. A research group at EPFL has now published ...
Discovery in parent of one high-temperature superconductor may lead to predictive control
(PhysOrg.com) -- A team of scientists studying the parent compound of a cuprate (copper-oxide) superconductor has discovered a link between two different states, or phases, of that matter - and written a mathematical ...
Engineers find a way to win in laser performance by losing
Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis.
World first superconducting DC power transmission system a step closer
New material holds big energy hope
(Phys.org) —A new material that can store large amounts of energy with very little energy loss has been developed by researchers at the Australian National University.
Physicists light 'magnetic fire' to reveal energy's path
New York University physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires, a finding that has the potential to deepen our understanding of self-sustained ...
