A brighter design emerges for low-cost, 'greener' LED light bulbs
The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given LED lighting a sales boost. However, that trend could be short-lived as key materials ...
Moon whets appetite for water
Scientists at the Carnegie Institution's Geophysical Laboratory, with colleagues, have discovered a much higher water content in the Moon's interior than previous studies. Their research suggests that the ...
Ocean floor muddies China's grip on '21st-century gold'
China's monopoly over rare-earth metals could be challenged by the discovery of massive deposits of these hi-tech minerals in mud on the Pacific floor, a study on Sunday suggests.
Studies would lead to lighter, cheaper magnets
(Phys.org) —Sometimes you have to apply a little pressure to get magnetic materials to reveal their secrets. By placing a permanent magnet under high pressures, Lawrence Livermore researchers are exploring ...
Towards quantum Internet with combined optical and electrical technique
An Australian team led by researchers at the University of New South Wales has achieved a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers - connected ...
Researchers see rare-earth-like magnetic properties in iron
(Phys.org) —Scientists at the Department of Energy's Ames Laboratory have observed magnetic properties typically associated with those observed in rare-earth elements in iron. These properties are observed ...
Rare earth elements in US not so rare: report
Approximately 13 million metric tons of rare earth elements (REE) exist within known deposits in the United States, according to the first-ever nationwide estimate of these elements by the U.S. Geological Survey.
Earth's rarest metals ranked in supply risk list
How ancient impacts made mining practical
About 1.85 billion years ago, in what would come to be known as Sudbury Canada, a 10 kilometer wide asteroid struck with such energy that it created an impact crater 250 kilometers wide. Today the chief industry of Sudbury ...
Experts: rare earths headed for 2011 supply crunch
Global demand for the increasingly important "rare earth" minerals that power a range of digital products could outstrip supply by next year as dominant producer China slashes exports, analysts warn.
Shooting for the moon -- to mine it
Most people don't take it literally when they're told to shoot for the moon - but thinking small isn't Naveen Jain's way. The 52-year-old Internet entrepreneur is a co-founder of Moon Express Inc., one of ...
Shift to green energy sources could mean crunch in supply of scarce metals
A large-scale shift from coal-fired electric power plants and gasoline-fueled cars to wind turbines and electric vehicles could increase demand for two already-scarce metals available almost exclusively ...
New technique to transform precious metal recovery
(Phys.org) —Murdoch University researchers have come up with a new approach to make the recovery of high value precious metals faster and more economically viable.
New family of tiny crystals glow bright in LED lights
(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.
