CHEMISTRY: Magnetic Catalysts

Nickel Particles as Catalysts in Hydrocarbon Chemistry

Deoxyribozymes: DNA catalysts for bioorganic chemistry.

Deoxyribozymes are DNA molecules with catalytic activity. For historical and practical reasons, essentially all reported deoxyribozymes catalyze reactions of nucleic acid substrates, although this is probably not a fundamental limitation. In vitro selection strategies have been used to identify many deoxyribozymes that catalyze RNA cleavage, RNA and DNA ligation, and a variety of covalent modif...

Meteorites as catalysts for prebiotic chemistry.

Meteorite late heavy bombardment was a major event after the accretion of the earth. The relevance of organic syntheses driven by impact shocks was first proposed by Chyba and Sagan in 1992, based on the scanty indications available at the time. How would the contribution by meteorites to an early earth organic pool compare with the syntheses these meteorites might have induced after their impa...

Also, He was also accepted for a Ph.D. in organic chemistry at the Bu-Ali Sina University in the same year. His research interest is the synthesis, cha...

High Magnetic Fields in Chemistry

Recent applications of large (∼ 1 T – ∼ 30 T) magnetic fields in modern chemical research are reviewed. Magnetic field effects of chemical relevance appear on the levels of quantum mechanics, thermodynamics, and macroscopic forces. Quantum mechanical magnetic field effects are governed by the Zeeman interaction and are borne out as static and dynamic effects in spectroscopy and in chemical kine...
