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.
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 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 ...
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 ...
Rocks on Mars may provide link to evidence of living organisms 4 billion years ago
A new article in press of the journal Earth and Planetary Science Letters unveils groundbreaking research on the hydrothermal formation of Clay-Carbonate rocks in the Nili Fossae region of Mars. The findin ...
Mystery mechanism drove global warming 55 million years ago
A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday.
'Holey' Nanosheets for Wastewater Dye Removal
Hurricanes not likely to disrupt ocean carbon balance
(PhysOrg.com) -- Hurricanes are well known for the trail of damage and debris they can leave on land, but less known for the invisible trail left over the ocean by their gale-force winds — a trail of carbon ...
What agricultural 'ecosystems on steroids' are doing to the air
In a study that identifies a new, "direct fingerprint" of human activity on Earth, scientists have found that agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere.
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 ...
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 ...
Saving trees in tropics could cut emissions by one-fifth, study shows
Reducing deforestation in the tropics would significantly cut the amount of carbon dioxide emitted into the atmosphere – by as much as one-fifth – research shows.
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.
