Dissipationless and scattering-free spin-based terahertz electronics is the futuristic technology for energy-efficient information processing. Femtosecond light pulse provides an ideal pathway exciting ferromagnet (FM) out-of-equilibrium, causing ultrafast demagnetization superdiffusive spin transport at sub-picosecond timescale, giving rise to transient radiation. Concomitantly, pulses also de...

Laser Raman spectra, UV-visible spectra, and photo-catalytic activity measurements are described which show that supported MoO,iTiOr catalysts prepared by impregnation possess a layer of surface molybdate species coordinated to the titania support. The saturation coverage of this surface molybdate monolayer corresponds to a surface density of ca. 4 x lOI MO atoms per cm2 of TiO*. The properties...
