Gold has been used as a therapeutic agent to treat a wide variety of rheumatic diseases including psoriatic arthritis, juvenile arthritis, and discoid lupus erythematosus. Although the use of gold has been largely superseded by newer drugs, gold nanoparticles are being used effectively in laboratory based clinical diagnostic methods while concurrently showing great promise in vivo either as a d...

Introduction Catalytic oxidations with O2 are one of the most important and widely studied reaction classes in heterogeneous catalysis. Metal oxides are of particular interest as catalysts because of the potential to replace expensive precious metals such as Pt and Pd. Despite the promising catalytic oxidation activities metal oxides have shown, practical applications are limited by surface poi...

Metal catalysis has a dominant role in modern organic chemistry. In particular, crosscoupling reactions allow bond formations, which have previously been impossible to perform.[1] Precious metal catalysts dominate the field, but alternative systems based on nickel and copper salts have also, historically, been important. In particular, recent systems based on these metals have been described th...

DATA on the distribution of the precious metals (Au, Ag and the platinum=group elements Ru, Rh, Pd, Os, Ir, Pt) are rapidly accumulating as a consequence of the application of microbeam analytical techniques such as the electron microprobe, the proton microprobe, and the ion microprobe. The new data obtained with these techniques build on knowledge accumulated over the last 140 years using bulk...

A catalyst is a substance that allows a chemical reaction to proceed at a faster rate than normally possible. Worldwide industry is dependent on catalysis to produce many products, such as plastics, hygiene products, and fertilizers. Precious metals like platinum and palladium are widely used in catalysis. These metals work very well due to their ability to accept and supply electrons (known as...
