Ultrasonic irradiation dramatically affects the reactivity of a variety of inorganic solids. We have found, for example, large increases in the rates of intercalation of a wide range of compounds into various layered inorganic solids (such as ZrS2, V2O5, TaS2 and MoO3. High intensity ultrasound also enhances the heterogeneous catalysis of alkene hydrogenation by Ni powders. Scanning electron mi...

During the last two decades, considerable progress has been made with the device efficiency and lifetime of organic lightemitting diodes (OLEDs), enabling their application in flatpanel displays and solid-state lighting. To realize high-performance, full-color OLED devices as commercial products, it is necessary to further improve the power efficiency and lifetime of the devices. To date, resea...

Fast Reacting Nano-Composite Energetic Materials: Synthesis and Combustion Characterization Report Title Energetic composites are mixtures of solid fuel and oxidizer particles that when combined offer higher calorific output than monomolecular explosives. The composites traditionally deliver energy as diffusion limited reactions and thus their power available from reaction is much smaller than ...

Dismantling nuclear facilities leads to radioactive waste less active but which may have highly variable compositions compared the high-level wastes recovered after reprocessing of spent fuel. In this work, we studied ability an alkali-rich glass matrix belonging SiO2-B2O3-Al2O3-Fe2O3-Na2O-Li2O-CaO system solubilize P2O5, MoO3, ZrO2 and Cs2O by melting at 1100°C. Phosphorus, molybdenum, zirconi...

A new potassium molybdenum oxide, K6Mo10O33, was synthesized by solid state reaction from the appropriate quantities of pre-dried MoO3 and K2MoO4, fired at around 650 ◦C for 2 d. The structure has been solved by using single crystal X-ray diffraction. The compound adopts the space group P1, with the lattice constants a = 7.7100(5), b = 11.9659(8), c = 17.1321(12) Å, α = 86.42 (10), β = 77.18(10...

H2MoO4 and H2WO4 upon direct laser desorption produce small clusters in the gas phase, extending up to 4500 and 7200 Da, respectively. The clustering patterns are quite similar for the two systems. The mass difference between successive peaks differ with increasing mass number as different kinds of structures become possible. A distinct planar to three-dimensional structural cross over is obser...
