A new study by University of Kentucky researchers shows how light and strained ruthenium-based drugs may be more effective at fighting cancer cells and less toxic to healthy cells than a similar and widely used drug. Cisplatin is a common platinum-based cancer drug. But while cisplatin kills cancer cells, it also attacks healthy cells, causing debilitating side effects. Ruthenium is a rare transition metal also belonging to the platinum group of the periodic table, and the UK researchers...

TSX: PFN OTCQX: PAWEF Frankfurt: P7J -- A technique has been developed to estimate the Rhodium (Rh), concentration of the Indicated and Measured Resource of the River Valley intrusion from Platinum (Pt) and Palladium (Pd) concentrations. -- The Rh content of the resource is estimated at~ 10% of the Pt content -- A significant proportion of the PGE's initially deposited in the conduit may still be...

Rice University lab's light-switching complex attaches itself to amyloid proteins A breakthrough in sensing at Rice University could make finding signs of Alzheimer's disease nearly as simple as switching on a light. The technique reported in the Journal of the American Chemical Society should help researchers design better medications to treat the devastating disease. The lab of Rice bioengineer Angel Martí is testing metallic molecules that naturally attach themselves to a...

How would you like to store all the films ever made on a device the size of an I-phone? Magnets made of just a few metallic atoms could make it possible to build radically smaller storage devices and have also recently been proposed as components for spintronics devices. There's just one obstacle on the way. Nano-sized magnets have only been seen to work at temperatures a few hairs above absolute zero. High temperature nanomagnets deviced by chemistry student Now a chemistry student at the...

Rice University lab uses ruthenium complexes to dissolve nanotubes, add functionality A 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...

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 developed the recovery...

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 GoldVest,...

Storing thermal energy in chemical could lead to advances in storage and portability Researchers 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 applications A 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...
