Nanosilicon rapidly splits water without light, heat, or electricity
Semiconductor 'shish kabob' nanostructures combine properties from different dimensions
New device stores electricity on silicon chips
(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.
Type and frequency of tropical clouds important for simulations of surface energy impact
Clouds are energy traffic cops, controlling how much sunlight reaches Earth. Pacific Northwest National Laboratory researchers used long-term observations to show that the sunlight stopping power of each ...
Why seashells' mineral forms differently in seawater
For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take ...
Enough wind to power global energy demand, new research says
There is enough energy available in winds to meet all of the world's demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- ...
Movement of pyrrole molecules defy 'classical' physics
(Phys.org) —New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.
Researchers achieve higher solar-cell efficiency with zinc-oxide coating
(Phys.org) —Engineering researchers at the University of Arkansas have achieved the highest efficiency ever in a 9 millimeter-squared solar cell made of gallium arsenide. After coating the cufflink-sized ...
X-ray laser breakthrough research shows chemical reaction in real time
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient ...
Cicadas get a jump on cleaning (w/ Video)
As cicadas on the East Coast begin emerging from their 17-year slumber, a spritz of dew drops is all they need to keep their wings fresh and clean. Researchers at Duke University and James Cook University ...
Building quantum states with individual silicon atoms
(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.
Researchers create 'nanoflowers' for energy storage, solar cells
(Phys.org)—Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous ...
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.
Folding light: Wrinkles and twists boost power from solar panels
Taking their cue from the humble leaf, researchers have used microscopic folds on the surface of photovoltaic material to significantly increase the power output of flexible, low-cost solar cells.
