摘要： For production of monocrystalline powders there is formed a melt to which a fluxing agent is added. The melt contains the components of a semiconductor material, an example being the components of copper indium diselenide which are generally used in a stoichiometric composition. The melt is usually heated to temperatures of between 300° C. and 1000° C. Monocrystalline powder grains grow. The desired recrystallization takes place at temperatures above the melting points of the materials to be fused. Once the powder grains have the desired size, the growth is stopped by quenching. The appropriate instant of quenching as well as the appropriate temperature profile for obtaining desired powder sizes are determined by, for example, preliminary experiments. Thereafter the fluxing agent is eliminated. Monograin membranes are produced from the powders produced according to the process and are used in particular in solar cells. The process is simple and inexpensive. Powder grains of uniform size are obtained.

摘要： A method of growing robust large area colloidal photonic crystals and devices produced thereby. A suspension of monosized colloidal spheres (1) is subjected to a composite shear (6) by applying a sequential set of shearing forces. The crystalline layers within the colloid experience shearing forces with components in both x and y directions, forcing the colloid into a singe face-centered-cubic structure in preference to a twinned face-centered-cubic structure. The method may also comprise the use of a dispersion medium which is capable of undergoing a controllable phase change from a liquid phase to a solid phase. The crystal may be fixed into a single face-centered cubic structure.

摘要： A method and apparatus for dynamically controlling the crystallization of molecules including a crystallization chamber (14) or chambers for holding molecules in a precipitant solution, one or more precipitant solution reservoirs (16, 18), communication passages (17, 19) respectively coupling the crystallization chamber(s) with each of the precipitant solution reservoirs, and transfer mechanisms (20, 21, 22, 24, 26, 28) configured to respectively transfer precipitant solution between each of the precipitant solution reservoirs and the crystallization chamber(s). The transfer mechanisms are interlocked to maintain a constant volume of precipitant solution in the crystallization chamber(s). Precipitant solutions of different concentrations are transferred into and out of the crystallization chamber(s) to adjust the concentration of precipitant in the crystallization chamber(s) to achieve precise control of the crystallization process. The method and apparatus can be used effectively to grow crystals under reduced gravity conditions such as microgravity conditions of space, and under conditions of reduced or enhanced effective gravity as induced by a powerful magnetic field.
