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
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.
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 ...
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 ...
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?
Plutonium tricks cells by 'pretending' to be iron
(PhysOrg.com) -- Plutonium gets taken up by our cells much as iron does, even though there's far less of it to go around.
An optical diode made with silicon technology can be used for quantum information
(PhysOrg.com) -- Transistors, resistors, capacitors, and diodes. All of these are examples of common electrical circuit elements that can be found on a computer motherboard, for instance. Billions of transistors ...
