New physics in a copper-iridium compound
(Phys.org) —An unexpected magnetic behavior within Sr3CuIrO6, a transition-metal compound (TMC) that combines the transition metal copper with the transition metal iridium has been revealed by research ...
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.
China rice laced with heavy metals: report
Up to 10 percent of rice grown in China is contaminated with harmful heavy metals but little has been done to highlight the possible public health risks, a report said.
German scientists produce first Bose-Einstein condensate with calcium atoms
Physicists at the Physikalisch-Technische Bundesanstalt (Germany) have succeeded in producing a Bose-Einstein condensate from the alkaline earth element calcium. The use of alkaline earth atoms creates new ...
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 ...
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 ...
Hubble sees cosmic riches
(Phys.org)—This dazzling image shows the globular cluster Messier 69, or M 69 for short, as viewed through the NASA/ESA Hubble Space Telescope. Globular clusters are dense collections of old stars. In this ...
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.
Clean energy could lead to scarce materials
As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.
Mastery of rare-earth elements vital to America's security
Karl A. Gschneidner Jr., a senior metallurgist at the U.S. Department of Energy's Ames Laboratory, today cautioned members of a Congressional panel that "rare-earth research in the USA on mineral extraction, ...
Alien earths could form earlier than expected
(Phys.org) -- Building a terrestrial planet requires raw materials that weren't available in the early history of the universe. The Big Bang filled space with hydrogen and helium. Chemical elements like silicon ...
Synthesis of a new lean rare earth permanent magnetic compound superior to Nd2Fe14B
A research group led by Dr. Kazuhiro Hono at the National Institute for Materials Science (NIMS) in Tsukuba, Japan, synthesized a new magnetic compound, which requires a lesser amount of rare earth element ...
Suzaku spies treasure trove of intergalactic metal
Every cook knows the ingredients for making bread: flour, water, yeast, and time. But what chemical elements are in the recipe of our universe?
