Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells.The new compounds, called dye-sensitized ruthenium nitrosyls, are absorbed by cancer cells and respond to specific wavelengths of light by releasing nitric oxide, which triggers cell death."For cancer treatment, you want localized delivery of a very high concentration of nitric oxide. We've designed these...

Canadian chemists say they have discovered green catalysts made from iron that might replace more expensive and toxic platinum metals. University of Toronto scientists said the newly discovered catalysts might become useful in industrial chemical processes used to produce drugs, fragrances and flavors. The researchers led by Professor Robert Morris said drug synthesis most often relies on the use of catalysts, while the cost of those catalysts influences the ultimate cost of the drug. And if...

Promising for cheaper drug production A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavors. The synthesis of drugs usually relies on the use of catalysts and the expense of the catalysts influences the ultimate cost of the drug. If the catalyst is toxic, as it...

Jlich scientists synthesize stable catalyst for water oxidationJlich scientists have made an important step on the long road to artificially mimicking photosynthesis. They were able to synthesize a stable inorganic metal oxide cluster, which enables the fast and effective oxidation of water to oxygen. This is reported by the German high-impact journal "Angewandte Chemie" in a publication rated as a VIP ("very important paper"). Artificial photosynthesis may decisively contribute to solving...

By Garg, Anurag Mishra, Indra M; Chand, Shri ABSTRACT: Wet-air oxidation of diluted black liquor (chemical oxygen demand [COD] approximately 3250 to 14 500 mg/L) was performed at mild operating conditions (temperature = 388 to 423 K and total pressure = 0.6 MPa) in the presence of heterogeneous 60% copper oxide (CuO)/ 40% cerium oxide (CeO^sub 2^) catalyst. Maximum COD reduction of 77.3% was obtained at 423 K at pH 3.0, which was marginally higher than that obtained at 413 K temperature...
