A catalytic knight's move

Article Abstract:

A novel combination of two catalytic reactions that are each celebrated reactions in their own right is described. The tandem reaction is the ability of the catalysts to work independently without interfering with each other and this ability to manipulate the length of carbon chains is a potentially useful step in processing saturated hydrocarbon sources for fuel and chemical uses, particularly in a future regime aiming to use alternative feedstocks to oil, such as biomass or natural gas.

Femtosecond dynamics of dissociation and recombination in solvent cages

Article Abstract:

Research on the femtosecond dynamics of the dissociation of iodine encaged in argon clusters reveals the dependence of the dissociation pathway on the time-scale on bond breaking relative to the time-scale of solvent rearrangement. Iodine atoms exhibit motion on a sub-picosecond time-scale, rebounding and recombining from the frozen solvent cage, when dissociation occurs from the A-type excited electron state of I2. Collision with the argon atoms then cools the 'hot' I2 molecules.
