Rice University lab uses ruthenium complexes to dissolve nanotubes, add functionalityA lab at Rice University has stepped forward with an efficient method to disperse nanotubes in a way that preserves their unique properties -- and adds more.The new technique allows inorganic metal complexes with different functionalities to remain in close contact with single-walled carbon nanotubes while keeping them separated in a solution.That separation is critical to manufacturers who want to spin fiber...

Tokyo, Nov 24, 2010 - (JCN Newswire) - Tokyo Electron Limited and Tanaka Kikinzoku Kogyo K.K.(1) announce the successful development of a recycling process for ruthenium precursors (CVD-ruthenium material) used in next generation semiconductor miniaturization technology.Ruthenium precursors which are disposed of without being collected as valuable resources can now be collected, refined, and re-used without returning them to ruthenium metal. Tokyo Electron Limited...

Steven Zoernack, partner at GoldVest, announces upward revision for price of Palladium to $900.00 an ounce. Palladium is one of a group of six metals often referred to as PGM's, which stands for Platinum Group Metals. This group includes the well-known Platinum and the relatively obscure metals called rhodium, iridium, ruthenium and osmium. Platinum is 15 times rarer than Gold. Palladium is rarer than Platinum. Washington, DC (PRWEB) November 22, 2010 Steven Zoernack, partner at...

Storing thermal energy in chemical could lead to advances in storage and portabilityResearchers at MIT have revealed exactly how a molecule called fulvalene diruthenium, which was discovered in 1996, works to store and release heat on demand. This understanding, reported in a paper published on Oct. 20 in the journal Angewandte Chemie, should make it possible to find similar chemicals based on more abundant, less expensive materials than ruthenium, and this could form the basis of a...

Could open way for medical, clean energy applicationsA new type of nanoparticle resembling the six-pointed Star of David (Magen David) that is the symbol on the flag of Israel has been discovered by researchers at the Hebrew University of Jerusalem. (One nanometer is a billionth of a meter.) The discovery, the researchers say, may lead to new ways for sensing of glucose in diagnosing diabetes or provide a catalyst to capture the sun's energy and turn it into clean fuel.Their work, they...

Energy from hydrogen "“ scientists from all over the world work on this solution to overcome the energy crisis. Amongst other things they try to use the sunlight as driving force for the splitting of water into hydrogen and oxygen. In trying to copy the photosynthesis in the laboratory a team of scientists of the Universities of Jena and Erlangen-Nürnberg and of the Institute of Photonic Technology (IPHT) in Jena (Germany) made a huge step forward. The physicists and chemists were able...

New details about the Piers catalyst will help chemical industry improve productsSome people have streets named after them. Warren Piers, a chemistry professor at the University of Calgary, has a catalyst penned after him.And in a paper published May 9 in the online edition of Nature Chemistry, Piers and former graduate student Edwin van der Eide reveal the inner workings of the Piers catalyst at a molecular level of detail not previously available."These details are critical for the...

To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have devised an unusual solution -- attach what amounts to a 3-D bramble patch to each side of the carbon sheet. Using that method, the scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, a first.The scientists' report, online today (April 9), will appear in a future issue of Nano Letters, an American Chemical Society journal."Our interest stems from...

Novel research tool from Scripps Florida could significantly expand search for new therapiesUsing a novel light activation technique, Scripps Research Institute scientists have been able to turn molecules with only a modest ability to fight specific proteins into virtual protein destroyers.The new technique, which uses a "warhead" molecule capable of inactivating nearby proteins when triggered by light, could help to accelerate the development of new therapies by providing...

Emory University chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight. The breakthrough, published March 11 in the journal Science, was made in collaboration with the Paris Institute of Molecular Chemistry.The fastest, carbon-free molecular water oxidation catalyst (WOC) to date "has really upped the standard from the other known homogeneous WOCs," said...
