Molten-air battery's storage capacity among the highest of any battery type
Zero-dimensional transistor harvests bubble energy wasted during water electrolysis
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Liberating devices from their power cords: New structural 'supercaps' take a lickin', keep on workin'
(Phys.org) —Imagine a future in which our electrical gadgets are no longer limited by plugs and external power sources. This intriguing prospect is one of the reasons for the current interest in building ...
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 ...
Lithium-sulfur batteries last longer with nanomaterial-packed cathode
Electric vehicles could travel farther and more renewable energy could be stored with lithium-sulfur batteries that use a unique powdery nanomaterial.
Simulating how the Earth kick-started metabolism
(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living ...
Driving down fuel usage: MIT spinout fits gas-guzzlers with electric powertrains, cutting gas consumption
Despite their potential to reduce carbon dioxide (CO2) emissions and fuel consumption, electric and hybrid cars and trucks struggled for years to find a solid customer base. Much of the reason came down to ...
Caps not the culprit in nanotube chirality
(Phys.org) —A single-walled carbon nanotube grows from the round cap down, so it's logical to think the cap's formation determines what follows. But according to researchers at Rice University, that's not ...
