Abstract: Metal chalcogenides, and methods of making and using metal chalcogenides, are disclosed herein. Metal chalcogenides can be prepared by heating suitable copper, zinc, and/or tin compounds selected from the group consisting of chalcogenocarbamates, dichalcogenocarbamates, mercaptides, thiiocarbonates, trithiocarbonates, and combinations thereof (e.g., copper, zinc, and/or tin dichalcogenocarbamates) under conditions effective to form metal can be used, for example, to prepare solar cells.

Abstract: A tampon pledget includes crosslinked cellulose fibers having microstructures treated to provide improved absorbency and higher wet strength. The fibers are treated with a crosslinking agent to provide at least one of a molecular weight between crosslinks of from about 10 to 200 and a degree of crystallinity of from about 25% to 75%. The crosslinking agent includes citric acid in 1% by weight. The crosslinking agent may further include sodium hypophosphite in 1% by weight. In another embodiment, the crosslinking agent may be a difunctional agent including a glyoxal or a glyoxal-derived resin. In still another embodiment, the crosslinking agent is a multifunctional agent including a cyclic urea, glyoxal, polyol condensate. The crosslinking agent is added in an amount from about 0.001% to 20% by weight based on a total weight of cellulose fibers to be treated and, preferably, in an amount of about 5% by weight.

Abstract: The present invention provides devices and methods for micro-scale simulated moving bed chromatography (SMB) for continuous preparation of analytic quantities of highly pure fractions of target molecules. The present apparatus and method of the invention is adapted in a preferred embodiment to separations by affinity chromatography involving three discontinuous liquid flow loops. An alternative embodiment of affinity chromatography utilizes standard SMB operating under isocratic conditions.
