Abstract: The solvated metal particle-coating system includes a metal additive and a polar outer-sphere electron transferring solvent. The metal additive is solvated in the polar outer-sphere electron transferring solvent. The polar outer-sphere electron transferring solvent may include liquid ammonia, methylamine, and/or hexamethylphosphoramide. The metal additive may include an alkali metal and/or an alkaline earth metal. The solvated metal additive within the polar outer-sphere electron transferring solvent may be used to coat a metal particle and/or a metalloid particle as a layer. As the polar outer-sphere electron transferring solvent evaporates, the solvated metal additive is coupled to the metal particle and/or the metalloid particle.

Abstract: A method and system for determining temperature are provided. The method comprises using an x-ray source to irradiate a sample of a material with x-rays. Photon fluorescence produced by the sample in response to the x-ray irradiation is detected by a number of photon detectors. Based on the detected fluorescence a temperature of the sample is determined according to a predetermined relationship between photon fluorescence and temperature for the material.

Abstract: A method for altering the course of a conflagration involving firing a projectile comprising a powder mixture of oxidant powder and nanosized reductant powder at velocity sufficient for a violent reaction between the oxidant powder and the nanosized reductant powder upon impact of the projectile, and causing impact of the projectile at a location chosen to draw a main fire to a spot fire at such location and thereby change the course of the conflagration, whereby the air near the chosen location is heated to a temperature sufficient to cause a spot fire at such location. The invention also includes a projectile useful for such method and said mixture preferably comprises a metastable intermolecular composite.

Abstract: A method to substantially desensitize a metastable intermolecular composite material to electrostatic discharge and friction comprising mixing the composite material with an organic diluent and removing enough organic diluent from the mixture to form a mixture with a substantially putty-like consistency, as well as a concomitant method of recovering the metastable intermolecular composite material.

Abstract: Tungsten trioxide hydrate (WO3.H2O) was prepared from a precursor solution of ammonium paratungstate in concentrated aqueous hydrochloric acid. The precursor solution was rapidly added to water, resulting in the crash precipitation of a yellow white powder identified as WO3.H2O nanosized platelets by x-ray diffraction and scanning electron microscopy. Annealing of the powder at 200° C. provided cubic phase WO3 nanopowder, and at 400° C. provided WO3 nanopowder as a mixture of monoclinic and orthorhombic phases.
