3D graphene: Solar cells' new platinum?
One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.
Researchers develop graphene supercapacitor holding promise for portable electronics
(PhysOrg.com) -- Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially ...
Team uses solar-powered proteins to filter harmful antibiotics from water
(Phys.org) —New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics ...
Researchers spin cotton into capacitive yarn
While the pattern for making a wearable fabric battery has already been laid out, it's now time to select the threads that will turn a textile into an energy storage device. That process is being driven by ...
New path to flex and stretch electronics: Researchers develop solution-based fabrication technique
(PhysOrg.com) -- Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make "smart devices" nearly ubiquitous. Among the ...
Soil's large carbon stores could be freed by increased CO2, plant growth
An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet—soil.
'Nanobionics' aims to give plants super powers
Plants are an engineering marvel of nature. Fueled by sunlight, they recycle our carbon dioxide waste into fresh oxygen for us to breathe. Plus, they make the world prettier. But, with a little help from us humans, can they ...
Violent eruptions in Mercury's past could hold clues to its formation
Volcanoes on Mercury may have been more explosive than previously anticipated, and they may have erupted more recently, as well.
Catalytic gold nanoclusters promise rich chemical yields
(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries ...
Figuring out how we get the nitrogen we need
(Phys.org) —Nitrogen is an essential component of all living systems, playing important roles in everything from proteins and nucleic acids to vitamins. It is the most abundant element in Earth's atmosphere ...
As fuel cells evolve, a role emerges for palladium
(Phys.org) —Researchers at Yale University have taken another step toward the development of low-temperature, lower-cost alkaline fuel cells, which are battery-like devices that convert oxygen and hydrogen ...
New study shows humans have more impact on tropical nitrogen levels
A new paper co-written by four University of Montana researchers finds that humans have more than doubled tropical nitrogen inputs.
Team uses forest waste to develop cheaper, greener supercapacitors
Researchers report that wood-biochar supercapacitors can produce as much power as today's activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts.
Scientists' gold discovery sheds light on catalysis
(Phys.org) -- A physicist at the University of York has played a key role in international research which has made an important advance in establishing the catalytic properties of gold at a nano level.
