Boron 'Buckyball' Discovered By Researchers
2014-07-14 03:29:25

By Kevin Stacey, Brown University The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers from Brown University, Shanxi University and Tsinghua University in China have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It's the first experimental evidence that a boron cage...

New Boron Nanomaterial Could Be A Very Real Possibility

Brown University Graphene, a sheet of carbon one atom thick, may soon have a new nanomaterial partner. In the lab and on supercomputers, chemical engineers have determined that a unique arrangement of 36 boron atoms in a flat disc with a hexagonal hole in the middle may be the preferred building blocks for “borophene.” Findings are reported in Nature Communications. Researchers from Brown University have shown experimentally that a boron-based competitor to graphene is a very real...

Theoretical Possibility Of Large, Hollow Magnetic Cage Molecules Discovered By VCU Physicists

Virginia Commonwealth University New molecules could be larger than the original Buckminster fullerene with potential applications in technology and health care Virginia Commonwealth University researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and in other emerging technologies. Approximately 25 years ago, scientists first made the...

New Carbon Form Can Indent Diamond
2012-08-17 09:33:27

April Flowers for redOrbit.com - Your Universe Online A new form of very hard carbon clusters capable of indenting diamond has been observed by a team of Carnegie Institution for Science researchers. The carbon clusters are unusual in their mix of crystalline and disordered structures and have potential applications for a range of mechanical, electronic, and electrochemical uses. The team, led by Lin Wang, published their findings in the August 17, 2012, issue of Science. Carbon...

Scientists at the Vienna University of Technology found a method to locate single gold atoms on a surface. This should pave the way to better and cheaper catalysts. Most people value large chunks of gold — but scientists at the Vienna University of Technology are interested in gold at the smallest possible scale, because single gold atoms are potentially the most reactive catalysts for chemical reactions. However, when gold atoms are placed on a surface they tend to ball up into tiny...

New way to highly efficient catalysts and nanotubes with unusual symmetry A doll in a doll, and then one more, enveloping them from the outside — this is how Thomas Faessler explains his molecule. He packs one atom in a cage within an atom framework. With their large surfaces these structures can serve as highly efficient catalysts. Just like in the Russian wooden toy, a hull of twelve copper atoms encases a single tin atom. This hull is, in turn, enveloped by 20 further tin atoms....

Like a shadowy character just hidden from view, a mystery atom in the middle of a complex enzyme called nitrogenase had long hindered scientists' ability to study the enzyme fully. But now an international team of scientists led by Serena DeBeer, Cornell assistant professor of chemistry and chemical biology, has pulled back the curtain using powerful synchrotron spectroscopy and computational modeling to reveal carbon as the once-elusive atom. The research was published online Nov. 17...

If we could make plant food from nitrogen the way nature does, we'd have a much greener method for manufacturing fertilizer — a process that requires such high temperatures and pressures that it consumes about 1.5 percent of the world's energy. Now scientists working at the Department of Energy's SLAC National Accelerator Laboratory have taken an important step towards understanding how nature performs this trick, by identifying a key atom that researchers had sought for more than a...

A study published by researchers at the RIKEN Advanced Science Institute (ASI) has shed first-ever light on a class of heterometallic molecular structures whose unique features point the way to breakthroughs in the development of lightweight fuel cell technology. The structures contain a previously-unexplored combination of rare-earth and d-transition metals ideally suited to the compact storage of hydrogen. The most abundant element in the universe, hydrogen holds great promise as a...
