    Abstract: The invention relates to an improved multiwell cluster plate. The wells of the plate each have an upper chamber and a lower chamber separated by a microporous membrane. Adjacent to each well is a corresponding access port. The access port is a separate opening in the tip surface of the plate which provides direct access to the lower chamber of the corresponding well, without disturbing the upper chamber or the membrane

    Abstract: A composite including an inorganic substrate having an outer surface from which pores extend into the substrate and a coating extending over the substrate's outer surface as a substantially uninterrupted layer of carbon. The coating penetrates into the pores of the inorganic substrate. The composite can be made by a process including the steps of contacting an inorganic substrate with a coating and impregnating liquid consisting essentially or wholly of a carbon precursor liquid, treating the inorganic substrate under conditions effective to cure substantially the carbon precursor liquid, and heating the inorganic substrate under conditions effective to convert substantially the cured carbon precursor liquid to carbon.

    Abstract: An optically activated bleaching process effective to permanently modify the color of surface-colored silver halide-containing photochromic glasses produced by thermal reduction treatments is described, wherein the glass is coincidentally exposed, for an effective time interval, to (i) a source of high energy light and (ii) a heat source. The process reduces the relatively strong absorption peaks characteristic of the initially colored glass, resulting in a permanent bleached appearance.

    Abstract: There is disclosed a fluorinated phyllosilicate material and method of producing such material. The material has fluoride ions chemically bonded to a natural phyllosilicate in part at least by exchange with hydroxyl ions. The method comprises exposing a phyllosilicate to a source of fluoride ions, either gaseous, aqueous fluoride solution, or a volatile solid, and chemically bonding flouride ions to the phyllosilicate structure. The fluorinated material may be heated to a temperature in the range of 100.degree.-1000.degree. C., preferably 300.degree.-800.degree. C. to dehydrate the material. Heating at 800.degree. C. may create new crystal phases, such as sellaite (MgF.sub.2) or fluorite (CaF.sub.2).

    Abstract: This invention is directed to the preparation of glass-ceramic materials especially suitable for use in multilayer substrates for integrated circuit packages. The inventive glass-ceramics are derived from thermally crystallizable glass which, in the form of frit, are capable of being sintered into an integral body at temperatures below 1000.degree. C. and essentially concurrently crystallized in situ to yield BPO.sub.4 as the predominant crystal phase. The inventive glass-ceramics exhibit a linear coefficient of thermal expansion between about 30-45.times.10.sup.-7 /.degree.C., a dielectric constant less than 5, and consist essentially, in weight percent, of 10-25% B.sub.2 O.sub.3, 20-40% P.sub.2 O.sub.5, and >50-65% SiO.sub.2.

    Abstract: There is disclosed a lithium aluminosilicate glass body encased within, and integral with, a thin, compressive, semicrystalline layer containing beta-eucryptite and/or beta-quartz solid solution crystals, and a method of producing such body. The layer has a substantially lower thermal coefficient of expansion than the glass, but has the same chemical composition as the glass. That composition, in percent by weight on a calculated oxide basis is 55-67% SiO.sub.2, 5.0-7.5% Li.sub.2 O, 22-28% Al.sub.2 O.sub.3, 0-2% Na.sub.2 O and 0-10% ZnO, the molar ratio of R.sub.2 O+RO to Al.sub.2 O.sub.3 being greater than one. Controlled crystallization procedure is described whereby the crystallized layer can be produced in a relatively short time.

    Abstract: A method is provided of preparing high-purity mixtures of zirconia and another metal oxide substantially free of sodium oxide impurity. Trioxydizirconium ion and a salt of another metal in an aqueous solution are added to a highly basic solution, resulting in the homogeneous precipitation of the combined hydroxides or hydrous oxides. The precipitate is recovered, washed with the water and then with an organic solvent, and then dried, most preferably employing an azeotropic distillation procedure. The resulting material is then calcined to provide a mixture of zirconia with the other metal oxide. In a preferred embodiment, the zirconia mixtures are in the form of fine powders which can be sintered to form a product having greater than 99% of its theoretical density.
