Selective photoctalytic oxidation of light alkanes over alkali-ion-modified V2O5/SiO2; Kinetic study and reaction mechanism

Article Abstract:

Acetone formation on the photooxidation of propane was investigated over a rubidium-ion-modified silica-supported vanadium oxide that is the most effective catalyst. The kinetic analysis demonstrated that the rate-determining step is the reaction of propane on the lattice oxygen of the photoexcited VO4Rb species to yield the vanadium isopropoxide species.

Spectroscopy and kinetics of a molecular memory with nondestructive readout for use in 2D and 3D storage systems

Article Abstract:

The new molecule designed and utilized as a molecular memory for optical storage is composed of a photochromatic fulgimide and a flourescent dye bonded, chemically, together to form a single molecule. The nondestructive readout and erase operations and prototype systems are presented, and a prototype optical disk is described.
