Abstract: The synthesis of actinide tetraborides including uranium tetraboride (UB4), plutonium tetraboride (PuB4) and thorium tetraboride (ThB4) by a solid-state metathesis reaction are demonstrated. The present method significantly lowers the temperature required to ≦850° C. As an example, when UCl4 is reacted with an excess of MgB2, at 850° C., crystalline UB4 is formed. Powder X-ray diffraction and ICP-AES data support the reduction of UCl3 as the initial step in the reaction. The UB4 product is purified by washing water and drying.

Abstract: End moldings for high-voltage cables are described wherein the dielectric insulator of the cable is heated and molded to conform to a desired shape. As a consequence, high quality substantially bubble-free cable connectors suitable for mating to premanufactured fittings are made. Disclosed is a method for making the cable connectors either in the field or in a factory, molds suitable for use with the method, and the molded cable connectors, themselves.

Abstract: A fluorescence in situ hybridization (FISH) procedure and solutions is provided. The entire FISH procedure is fast (15 minutes or less), with the hybridization step occurring in 5 minutes or less. The entire FISH procedure with digoxygenin- or biotin-labeled probes takes approximately 30 minutes. A formamide-free solution (dextran sulfate and glycerol) is provided. An additional solution (10% dextran sulfate and 20% formamide) is also provided. Additional solutions are provided for mRNA in situ hybridization whereby the process takes less than 24 hours.
