Unconventional superconductivity near absolute zero temperature

Quantum critical point could be the reason for high temperature superconductivity


Researchers at the Goethe University have discovered an important mechanism for superconductivity in a metallic compound containing ytterbium, rhodium and silicon. As reported by Cornelius Krellner and his colleagues the underlying concept of the quantum-critical point has long been discussed as ...


A breakthrough for organic reactions in water


Green-chemistry researchers at McGill University have discovered a way to use water as a solvent in one of the reactions most widely used to synthesize chemical products and pharmaceuticals. The findings mark a potential milestone in efforts to develop organic reactions in water. Chao-Jun Li and ...


Supercomputers join search for 'cheapium'


In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power. In a new study, researchers from Duke University’s Pratt School of Engineering used computational methods to ...


Iron-based process promises greener, cheaper and safer drug and perfume production


University of Toronto researchers have developed a series of techniques to create a variety of very active iron-based catalysts necessary to produce the alcohols and amines used in the drug and perfume industry. The new synthetic methods promise to be safer and more economical and environmentally ...


Dr. Thomas A. Puckette Honored as Recipient of 2011 Paul N. Rylander Award


Dr. Thomas A. Puckette, an Eastman Chemical Company Technology Fellow based in Longview, Texas, received the 2011 Paul N. Rylander Award at the 24th Biennial ORCS Conference in Annapolis, Maryland, on April 16, 2012. The BASF sponsored award is presented annually to researchers who have made ...


New technology expands ability to recycle precious metals

Strategic partnership between Heraeus and PhosphonicS


Precious metals like platinum and rhodium are very valuable, and also very rare. That makes it increasingly important to recycle these precious metals from a wide variety of industrial uses. For example, various catalytic processes in the chemical industry generate large amounts of fluid residue ...


For platinum catalysts, smaller may be better


When it comes to metal catalysts, the platinum standard is, well, platinum! However, at about $2,000 an ounce, platinum is more expensive than gold. The high cost of the raw material presents major challenges for the future wide scale use of platinum in fuel cells. Research at the U.S. Department ...


Synthetic enzymes could help ID proteins

'Smart' catalysts programmed to recognize specific molecular shape


Using a rare metal that's not utilized by nature, Rice University chemists have created a synthetic enzyme that could help unlock the identities of thousands of difficult-to-study proteins, including many that play key roles in cancer and other diseases. The research was published online in the ...


First metallic nanoparticles resistant to extreme heat

Just as a gecko sheds its tail, metal-alloy particles endure 850 degrees Celsius by ditching weaker components, researchers report in Nature Materials


A University of Pittsburgh team overcame a major hurdle plaguing the development of nanomaterials such as those that could lead to more efficient catalysts used to produce hydrogen and render car exhaust less toxic. The researchers reported Nov. 29 in Nature Materials the first demonstration of ...

New molecules created by UC Riverside chemists have wide applications

Guy Bertrand's lab shows metal-free 'abnormal N-heterocyclic carbenes' are stable, allowing their use in numerous catalytic chemical reactions


Researchers at the University of California, Riverside have successfully created in the laboratory a class of carbenes, highly reactive molecules, used to make catalysts – substances that facilitate chemical reactions. Until now, chemists believed these carbenes, called "abnormal N-heterocyclic ...
