Spin-coating of chalcogenide glass is a low-cost, scalable method to create optical grade thin films, which are ideal for visible and infrared applications. In this paper, we study the influence of annealing on optical parameters of As(2)S(3) films by examining UV-visible and infrared spectroscopy and correlating the results to changes in the physical properties associated with solvent removal....

We have demonstrated an improved synthesis of a cyclic carbonate of soybean oil (CSO) utilizing supercritical carbon dioxide (CO2) as the solvent. Because the mutual solubility of supercritical CO2 and soybean oil is significantly higher than that of gaseous CO2 and soybean oil, our method synthesizes the material in y1/3 of the reaction time reported in the literature. We have also demonstrate...

The implementation of four bidentate building blocks into a high-denticity linker with a flexible spacer leads to a predisposed ligand that allows one to direct the self-assembly of 1D functional coordination polymers. This is illustrated by the assembly under mild conditions of the luminescent metal-organic framework [Tb(Htpabn)] . 14H2O infinity (1; H4tpabn = N,N,N',N'-tetrakis[(6-carboxypyri...

Effects of four organic solvents--methanol, trifluoroethanol, dimethylsulfoxide, and dimethylformamide (DMF)--on the ferritin-binding activity of three monoclonal mouse antibodies of IgG2a and IgG1 subclasses were studied. The ferritin-binding constants of monoclonal antibodies G10 and F11 (the IgG2a subclass) were increased 2-6-fold after incubation with DMF and removal of the organic solvent ...

This reaction is equilibrium-limited to 95 to 97% conversion in 2 to 4 stages because the temperature must be kept above the dewpoint of sulfur. Additional processing must be provided to reduce the concentration of sulfurous compounds in the effluent to environmentally acceptable levels. When the reaction between H2S and SO2 is carried out in organic liquids at temperatures below 15OoC it is ir...
