Solar wind and space dust create new source of water, laboratory study suggests
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation, but not all. John Bradley of Lawrence Livermore National Laboratory and his team may ...
A tree may have the answers to renewable energy
Through an energy conversion process that mimics that of a tree, a University of Wisconsin-Madison materials scientist is making strides in renewable energy technologies for producing hydrogen.
Will the sun explode?
All stars die, some more violently than others.
Five times less platinum: Fuel cells could become economically more attractive thanks to novel aerogel catalyst
Fuel cells that convert hydrogen into power and only produce pure water as a by-product have the potential to lead individual mobility into an environmentally friendly future. The Paul Scherrer Institute ...
An improved, cost-effective catalyst for water-splitting devices
By replacing platinum with molybdenum in photoelectrochemical cells, scientists from two EPFL labs have developed a cheaper and scalable technique that can greatly improve hydrogen production through water ...
'Super-Earths' may be dead worlds
In the last 20 years the search for Earth-like planets around other stars has accelerated, with the launch of missions like the Kepler space telescope. Using these and observatories on the ground, astronomers ...
'Peanut' particles could be used to build micro-scale factories
Water found to be an ideal lubricant for nanomachines
Researchers from the University of Amsterdam have discovered that machines just one molecule in size move far quicker if you add a 'lubricant' to their surroundings. To their surprise, water proved to be ...
Newly discovered galaxy mirrors conditions after the Big Bang
Using one of the world's premier telescopes, University of Minnesota astrophysicists Evan Skillman and Kristen McQuinn have discovered a priceless relic of the Big Bang in the Milky Way's back yard.
Hyundai to market hydrogen vehicle next year (Update)
For years, the joke in the auto industry was that a mass-produced car that runs on hydrogen was always a decade away.
Water and sunlight the formula for sustainable fuel
An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen ...
Hydrogen cars could be headed to showroom near you (Update)
Cars that run on hydrogen and exhaust only water vapor are emerging to challenge electric vehicles as the world's transportation of the future.
When a black hole shreds a star, a bright flare tells the story
(Phys.org) —Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported ...
One step to solar-cell efficiency: Researchers' chemical process may improve manufacturing
Rice University scientists have created a one-step process for producing highly efficient materials that let the maximum amount of sunlight reach a solar cell.
