Regulating electron 'spin' may be key to making organic solar cells competitive
Organic solar cells that convert light to electricity using carbon-based molecules have shown promise as a versatile energy source but have not been able to match the efficiency of their silicon-based counterparts.
Unique salt allows energy production to move inland
Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, Penn State researchers can combine bacterial ...
Study resets date of earliest animal life by 30 million years
University of Alberta researchers have uncovered physical proof that animals existed 585 million years ago, 30 million years earlier than all previous established records show.
Manufacturing method paves way for commercially viable quantum dot-based LEDs
University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither.
Novel filter metal-organic framework material could cut natural gas refining costs
A new type of hybrid material developed at the University of California, Berkeley, could help oil and chemical companies save energy and money and lower their environmental impacts by eliminating ...
Evolution inspires more efficient solar cell design: Geometric pattern maximizes time light is trapped in solar cell
(Phys.org)—The sun's energy is virtually limitless, but harnessing its electricity with today's single-crystal silicon solar cells is extremely expensive—10 times pricier than coal, according to some ...
Japan sensor will let diaper say baby needs changing
A disposable organic sensor that can be embedded in a diaper and wirelessly let a carer know it needs changing was unveiled by Japanese researchers on Monday.
Scientists find microbes in lava tube living in conditions like those on Mars
(PhysOrg.com) -- A team of scientists from Oregon has collected microbes from ice within a lava tube in the Cascade Mountains and found that they thrive in cold, Mars-like conditions.
Building crystalline materials from nanoparticles and DNA
Nature is a master builder. Using a bottom-up approach, nature takes tiny atoms and, through chemical bonding, makes crystalline materials, like diamonds, silicon and even table salt. In all of them, the properties of the ...
Electron spin transport demonstrated for first time in an organic device
(Phys.org)—Researchers in the Semiconductor and Dimensional Metrology Division's Nanoelectronic Device Metrology (NEDM) Project have demonstrated the first documented case of electron spin transport in ...
Hidden soil fungus, now revealed, is in a class all its own
A type of fungus that's been lurking underground for millions of years, previously known to science only through its DNA, has been cultured, photographed, named and assigned a place on the tree of life.
Faster organic semiconductors for flexible displays can be developed quickly with new method
(PhysOrg.com) -- Organic semiconductors hold immense promise for use in thin film and flexible displays picture an iPad you can roll up but they havent yet reached the speeds needed to ...
We may all be Martians: New research supports theory that life started on Mars
New evidence has emerged which supports the long-debated theory that life on Earth may have started on Mars.
