New connection between stacked solar cells can handle energy of 70,000 suns
(Phys.org) —North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar ...
When less is more: Fewer proton relays improve catalytic rates
(Phys.org) —By directly comparing three closely related catalysts, scientists at the Center for Molecular Electrocatalysis established that hydrogen production speed and efficiency are influenced by the ...
Fungal-bacterial consortia turn corn stalks and leaves into better biofuel
A fungus and E. coli bacteria have joined forces to turn tough, waste plant material into isobutanol, a biofuel that matches gasoline's properties better than ethanol.
Superconducting material limits short-circuit currents
Siemens develops superconducting fault current limiters for limiting short-circuit currents in the grid. Superconductors show zero resistance below the critical temperature and below the critical current. ...
Nanocrystals and nickel catalyst substantially improve light-based hydrogen production
Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal ...
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.
Renewable energy obtained from wastewater
Researchers from the Universitat Autònoma de Barcelona have devised an efficient way to obtain electrical energy and hydrogen by using a wastewater treatment process. The proposed system, published in Water Research, uses b ...
Nanowires have the power to revolutionize solar energy (w/ video)
(Phys.org) —Capture up to 12 times more light to produce more energy? Nanowires do just that and surpass expectations on solar energy production.
Chemists develop liquid-based hydrogen storage material
University of Oregon chemists have developed a boron-nitrogen-based liquid-phase storage material for hydrogen that works safely at room temperature and is both air- and moisture-stable -- an accomplishment ...
Air, water and sun: The ingredients of 'green gasoline'
(Phys.org) —Mimicking a natural process perfected over billions of years to capture solar energy, researchers are creating artificial photosynthetic systems that will turn air and water into transport fuel.
