Abstract: The present invention involves a treatment technique for drastically reducing the volume of hazardous sludge generated by the chemical reduction of chromium contaminants and the precipitation of heavy metal contaminants from contaminated electroplating wastewater. The wastewater is first adjusted to a pH of from about 8 to 10 and then treated with sodium sulfide to provide sulfide ions to effect precipitation of heavy metal contaminants followed by treatment with ferrous sulfate or ferrous chloride to provide ferrous ions to chemically reduce the hexavalent chromium to its trivalent state. This method produces approximately one-fourth the sludge generated by the previously known acidic reaction treatment using only ferrous sulfide.

Abstract: A method for the pyrolytic destruction of microfilm products by utilizing hot silicon oil heated to a temperature of about 250.degree. C. Destruction of the various types of microfilm is accomplished within a five minute time frame.

Abstract: The present invention accomplishes the thermal oxidation of the silicon side of the interface present in epitaxial silicon films grown on yttria-stabilized cubic zirconia, <Si>/<YSZ>, to form a dual-layer structure of <Si>/amorphous SiO.sub.2 /<YSZ>. The SiO.sub.2 films are formed in either dry oxygen (at 1100.degree. C.) or in pyrogenic steam (at 925.degree. C.) by the rapid diffusion of oxidizing species through a 425 .mu.m thick cubic zirconia substrate. For instance, a 0.17 .mu.m thick SiO.sub.2 layer is obtained after 100 min in pyrogenic steam at 925.degree. C. This relatively easy transport of oxidants is unique to YSZ and other insulators which are also superionic oxygen conductors, and cannot be achieved in other existing Si/insulator systems, such as silicon-on-sapphire.

Abstract: A novel treatment method for recovering halogenated vacuum pump oils such as chlorotrifluoroethylene, from contaminated filter papers.

Abstract: This invention describes a modified method of growing high purity, compositionally ungraded, single crystals of multicomponent solid solutions by the Czochralski, Kyropoulos, Bridgman or other related melt growth technique. In the method of this invention, the container or crucible used to contain the multicomponent crystal growing melt is fabricated from the higher melting point component of the multicomponent melt while lower melting point components are positioned within the crucible. The temperature of the crucible is then raised beyond the melting point of the lower melting point component to a temperature which is the exact melting point of the solid solution, or crystal alloy desired. This will dissolve an amount of the crucible material (higher melting point component) equal to the exact amount required to produce a solid solution having the desired composition.

Abstract: Geminal dinitro compounds are prepared by reacting an organic nitro compound having a replaceable hydrogen on the carbon to which the nitro group is attached with a source of nitrite ions in the presence of an oxidizing agent and a catalytic amount of an alkali metal ferricyanide.

Abstract: The present invention provides a method for synthesizing a novel oxether-1 monomer by a two step reaction scheme which involves effecting a reaction between 3-methyl-3-hydroxymethyl oxetane and 1,1,1-trinitroethane to form an intermediate reaction product which in turn is reacted with methyl iodide to produce the oxether-1 monomer. The monomer is easily polymerized using conventional polymerization techniques to produce a poly(oxether-1) polyol useful as a binder component in smokeless propellants and explosives.

The turnover temperatures of these resonators are between 60.degree. C. and 200.degree. C.
