He used it to solve the structure of a newly synthesized form of pure boron that displays some unusual physical properties and brings a surprise: it is partially ionic.New phase of elemental b...
Life Sciences |Oregon researchers have synthesized an elusive metal-hydroxide compound in sufficient and rapidly produced yields, potentially paving the way for improved precursor inks that could boost semiconductor...
Life Sciences |For most of us, gold is only valuable if we possess it in large-sized pieces. However, the “bigger is better” rule isn’t the case for those interested in exploiting gold’s exceptional ability to catal...
Physics and Astronomy |Few materials have exercised as much of a hold on the human imagination, or on human history, as has gold.But for all of its popular uses – money, medals, jewelry and more – gold's potent...
Life Sciences |“While gold nanoparticles are being used by so many researchers – chemists, materials scientists and biomedical engineers – no one understood their molecular and electronic structures until now,” said...
Studies and Analyses |It was known nanometer sized clusters of plutonium oxide were the culprit, but no one had been able to study its structure or find a way to separate it from the groundwater. Scientists at the ...
Power and Electrical Engineering |Already the evidence is present for a revolution in the manufacture of materials based on nano-engineered structures. However, prior to these “nanomaterials” becoming dominant in the marketplace a pre...
Physics and Astronomy |In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires. They also found that up to a certain length, oxygenated gold na...
Physics and Astronomy |Now, by creating a quantum mechanical analog of Ulam’s conjecture, researchers at the University of Illinois and the University of California have expanded the flexibility and controllability of quant...

Physics and Astronomy |The results provide information about the process of ice nucleation at a molecular level and take science a significant step closer to understanding the mysterious process through which ice forms arou...
Physics and Astronomy |These tiny tubes are constructed from carbon atoms and they are so small that it takes about 100,000 laid side-by-side to span the width of a single human hair. In the last five years, scientists have...
Life Sciences |Understanding the electronic and geometric structures of gold nanoclusters is a key step towards understanding their behavior under different conditions, such as their use as nanocatalysts or in certa...
Physics and Astronomy |The finding – that the dimensionality and structure, and thus the catalytic activity, of gold nanoclusters changes as the thickness of their supporting metal-oxide films is varied – is an important on...
Physics and Astronomy |Researchers at the Georgia Institute of Technology have uncovered important evidence that explains how water, usually an inhibitor of catalytic reactions, can sometimes promote them. The f...
