Champion nano-rust for producing solar hydrogen
EPFL and Technion researchers have figured out the "champion" nanostructures able to produce hydrogen in the most environmentally friendly and cheap manner, by simply using daylight.
Researchers calculate radiation exposure associated with journey to Mars
On November 26, 2011, the Mars Science Laboratory began a 253-day, 560-million-kilometer journey to deliver the Curiosity rover to the Red Planet. En route, the Southwest Research Institute-led Radiation ...
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
8th century gamma ray burst irradiated the Earth, study finds
(Phys.org)—A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri ...
Houston, we have another problem: Study shows space travel is harmful to the brain
(Phys.org)—As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missio ...
Flexible silicon solar-cell fabrics may soon become possible
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility ...
Clear link between solar activity and winter weather revealed
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
New technology uses solar UV to disinfect drinking water
(PhysOrg.com) -- A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
Metal particle generates new hope for H2 energy
(PhysOrg.com) -- Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy.
Dwarf planet Haumea shines with crystalline ice
The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic elements. This ...
'Quantum coaxial cable': Device proves solar cell potential of high bandgap inorganic nanowire arrays
A report, published in the March 14 edition of the Journal of Materials Chemistry, announced the successful fabrication and testing of a new type solar cell using an inorganic core/shell nanowire structure.
Earth is getting dustier, model suggests
(PhysOrg.com) -- If the house seems dustier than it used to be, it may not be a reflection on your housekeeping skills. The amount of dust in the Earth's atmosphere has doubled over the last century, according ...
Role of natural aerosols in climate uncertainties underestimated
Natural aerosols, such as emissions from volcanoes or plants, may contribute more uncertainty than previously thought to estimates of how the climate might respond to greenhouse gas emissions.
Cleaner and greener cities with integrated transparent solar cells
Imagine buildings in which the windows allow the sun's light to enter, and at the same time capture the energy from the sun needed to meet all their energy needs. In this seemingly futuristic scenario, the ...
