Abstract: A method of making a cubic halide scintillator material includes pressing a powder mixture of cubic halide and at least one activator under conditions of pressure, temperature, residence time and particle size effective to provide a polycrystalline sintered cubic halide scintillator having a pulse height resolution of from about 7% to about 20%. The conditions include a temperature ranging from about ambient temperature up to about 90% of the melting point of the cubic halide, a pressure of from about 30,000 psi to about 200,000 psi, a pressing residence time of from about 5 minutes to about 120 minutes and an average cubic halide particle size of from about 60 micrometers to about 275 micrometers.

Abstract: Embodiments for an apparatus and method for depositing one or more layers onto a substrate or a freestanding shape inside a reaction chamber operating at a temperature of at least 700° C. and 100 torr are provided. The apparatus is provided with a feeding system having injection means for differential pre-reactions and/or pre-treating of a plurality of gases or gas mixtures, tailoring the distribution of a plurality of gas-phase species, yielding a deposit that is substantially uniform in thickness and chemical composition along the substrate surface. In one embodiment, the apparatus further comprises a sacrificial substrate that further helps achieving thickness and chemical uniformity on the substrate, by imitating a continuous surface to deposit on and thus preventing any disturbances in the flow pattern especially towards the edge of the substrate.

Abstract: Disclosed herein is a crack-free protective coating comprising at least one of aluminum nitride, aluminum oxide, aluminum oxynitride or combinations thereof. Disclosed herein too is a method for making an article comprising disposing a protective coating comprising at least one of aluminum nitride, aluminum oxide, aluminum oxynitride or combinations thereof upon a substrate comprising pyrolytic boron nitride, pyrolytic graphite and/or carbon doped boron nitride.

Abstract: The process of the present invention is directed to a dry cleaning process, comprising the use of volatile cyclic, linear or branched siloxanes in the vapor phase for the cleaning of soiled or stained fabrics. The linear or branched siloxanes have the formula: M2+y+2zDxTyQz wherein M is R13SiO1/2; D is R2R3SiO2/2; T is R4SiO3/2; and Q is SiO4/2 R1, R2, R3 and R4 are each independently a monovalent hydrocarbon radical having from one to forty carbon atoms; and x and y are each integers, wherein 0≦x≦10 and 0≦y≦10 and 0≦z≦10. While the cyclic siloxanes have the formula: wherein R5, R6, R7 and R8 are each independently a monovalent hydrocarbon group having from one to forty carbon atoms; and a and b are each integers wherein 0≦a≦10 and 0≦b≦10, provided that 3≦(a+b)≦10.
