A process for the photochemical dehydrogenation of alcohols comprises the steps of forming a suspension of semiconductor powder in the alcohol and photochemically activating the suspension in the presence of an oxidant with illumination having an energy at least equal to the band gap of the semiconductor powder. The process is one carried out at about ambient temperature and with gentle agitation. The semiconductor powder has the general formula A.sub.x B.sub.y C.sub.z where A is selected from Bi, Sn, Pt, Pd, Cu, Fe, W, V, Sb, Mo, Ru or Ag and mixtures thereof; B is Te, Sb, Ti, Cd, Mo, W or V and mixtures thereof; C is O or S; x equals 0.1 to 5; y equals 1 to 3; and z is a number necessary to satisfy the other elements, and is optionally metallized by an element selected from Pt, Pd, Cu or Ag.

A process for the selective oxidation of olefins comprises the steps of forming a suspension of semiconductor powder in a solvent media, adding an olefin to the solvent media in the presence of an oxidant to form a mixture and, photochemically activating the mixture with illumination having an energy at least equal to the band gap of the semiconductor powder wherein the selectivity is controlled by the selection of A, of the solvent and of the oxidant. The process is one carried out at about ambient temperature and with gentle agitation. The semiconductor powder has the general formula A.sub.x B.sub.y C.sub.z where A is selected from Bi, Sn, Pt, Pd, Cu, Fe, W, V, Sb, Mo, Ru or Ag and mixtures thereof; B is Te, Sb, Ti, Cd, Mo, V or W and mixtures thereof; C is O or S; x equals 0 to 5; y equals 1 to 3; and z is a number necessary to satisfy the other elements, and is optionally metallized by an element selected from Pt, Pd, Cu or Ag.
摘要:
There is provided a method and device for remote sampling, preparation and optical interrogation of a sample using light scattering and light absorption methods. The portable device is a filtration-based device that removes interfering background particle material from the sample matrix by segregating or filtering the chosen analyte from the sample solution or matrix while allowing the interfering background particles to be pumped out of the device. The segregated analyte is then suspended in a diluent for analysis. The device is capable of calculating an initial concentration of the analyte, as well as diluting the analyte such that reliable optical measurements can be made. Suitable analytes include cells, microorganisms, bioparticles, pathogens and diseases. Sample matrixes include biological fluids such as blood and urine, as well as environmental samples including waste water.
摘要:
A system and method for taking orders for, and on-demand manufacturing of, personalized plastic event/party plates that may either be saved and reused or disposed of and recycled. In any given order, any number of plates may have a single unique high resolution photograph, or every plate may have a unique and different photograph. The images are preprinted on plastic film and are molded into the plate to become a permanent feature of the plate.

A process for preparing a crystalline, carbapenem monosodium salt of formula IIa: characterized by the steps a) adding about 10 to 30% of an organic solvent to an aqueous solution of the carbapenem, b) cooling the resulting solution to less than −5° C., c) adjusting the pH using a solution containing an acid in an organic solvent to give the appropriate pH for crystallization, and d) crystallizing the compound by adding methanol, and a C2-5 alcohol at between −5 and −25° C.
