Physicists confine electrons inside nano-pyramids
(Phys.org)—Quantum dots are nanostructures of semiconducting materials that behave a lot like single atoms and are very easy to produce. Given their special properties, researchers see huge potential for ...
Non-equilibrium quantum states in atmospheric chemistry
(Phys.org)—Research that sheds new light on the microscopic chemical physics driving one of the most important reaction sequences in atmospheric chemistry is published in Science today by Dr David Glowac ...
New protein discovered gives insights to iron's fate underground
(Phys.org) -- It's almost an evil twin story: a protein that steals electrons from iron in one microbe looks a lot like one that adds electrons in another microbe, according to scientists at Pacific Northwest ...
US carbon emissions in surprise drop
US emissions of carbon dioxide blamed for climate change fell in 2011 and have slipped to a 20-year low this year as the the world's largest economy uses more natural gas and less coal, data shows.
Physicists achieve world's first violet nonpolar vertical-cavity laser technology
In a leap forward for laser technology, a team at University of California, Santa Barbara, has developed the first violet nonpolar vertical-cavity surface-emitting lasers (VCSELs) based on m-plane gallium ...
Britain best in energy efficiency as US lags: report
Britain is a champion of energy efficiency while the United States and Canada lag behind in conserving power, according to a new report released Thursday.
Graphite enters different states of matter
(Phys.org) -- For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
US grabs lead over China in clean energy race
The United States has regained the lead in the clean energy race, investing $48 billion last year to surpass China, which held the world's top spending spot since 2009, said a study Wednesday.
Reduction in US carbon emissions attributed to cheaper natural gas
In 2009, when the United States fell into economic recession, greenhouse gas emissions also fell, by 6.59 percent relative to 2008.
Foldit gamers improve protein design through crowdsourcing
Fingerprinting uranium: X-rays identify mobile, stationary forms of atomic pollutant
(PhysOrg.com) -- Determining if uranium will zip through the soil or not is easier now, thanks to scientists at Pacific Northwest National Laboratory and the University of North Texas. Dr. Eugene Ilton and ...
Small reactors could figure into US energy future
A newly released study from the Energy Policy Institute at the University of Chicago (EPIC) concludes that small modular reactors may hold the key to the future of U.S. nuclear power generation.
Research team shows nuclear clock could be 60 times more accurate than atomic clock
New knowledge about 'flawed' diamonds could speed the development of diamond-based quantum computers
A University at Buffalo-led research team has established the presence of a dynamic Jahn-Teller effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications ...
