Abstract: The technology provides arrays of microwells with reversible shape for culture, analysis, and recovery of individual cells or groups of cells. The microwells are reversibly formed by vacuum-induced deflection of an elastomeric membrane into an array of microwell molds formed in a microwell substrate. The shape of each microwell or groups of microwells can be selectively altered by applying or releasing vacuum to individual microwells. The devices, systems, and methods utilizing the technology enable collection of individual cells for further study or therapeutic use without the need for micromanipulation.

Abstract: The invention relates to a preparation method for a magnesium matrix composite. The preparation method comprises the following steps: (1) preparing magnesium ingots as raw materials and salt flux and reinforcements; (2) placing the salt flux in a crucible, performing heating to prepare salt flux melts, adding the reinforcements; (3) performing pouring into a normal-temperature crucible, and performing cooling to obtain precursors; (4) adding the raw materials in an iron crucible, and performing melting at 953K-1043K; (5) placing the precursors in raw material melt, after stirring, under a condition of 953K-993K, performing standing so that scum and melt are obtained; and (6) removing the scum, lowering temperature to 973K-982K, and performing casting. The method provided by the present invention is simple in process and low in cost. The method can be used for preparing bulk structural members of the magnesium matrix composite, and can be used for automatic production.

Abstract: An apparatus and corresponding method for frontal face synthesis. The apparatus comprises a decoder that synthesizes a high-resolution (HR) frontal-view (FV) image of a face from received features of a low-resolution (LR) non-frontal-view (NFV) image of the face. The HR FV image is of a higher resolution relative to a lower resolution of the LR NFV image. The decoder includes a main path and an auxiliary path. The auxiliary path produces auxiliary-path features from the received features and feeds the auxiliary-path features produced into the main path for synthesizing the HR FV image. The auxiliary-path features represent a HR NFV image of the face at the higher resolution. As such, an HR identity-preserved frontal face can be synthesized from one or many LR faces with various poses and may be used in types of commercial applications, such as video surveillance.

Abstract: The invention relates to a method for preparing titanium alloys based on aluminothermic self-propagating gradient reduction and slag-washing refining, and belongs to the technical field of titanium-aluminum alloys. The method comprises the following steps of pre-treating raw materials, weighing the raw materials in the mass ratio of rutile or high-titanium slags or titanium dioxide to aluminum powder to V2O5 powder to CaO to KClO3 being 1.0:(0.60-0.24):(0.042-0.048):(0.12-0.26):(0.22-0.30), performing an aluminothermic self-propagating reaction in a gradient feeding manner to obtain high-temperature melt, performing a gradient reduction melting, performing heat insulation and separating the melt after the feeding is completed, then adding CaF2—CaO—TiO2—V2O5 based refining slags into the high-temperature melt, performing slag washing refining, and finally removing slags to obtain titanium alloys. This method has the advantages including short flow, low energy consumption, easy operation, easy control on Al and V contained in alloys, and so on.

Abstract: A preparation method for a plant growth agent for ecological water retention, fertilizer saving and production increase promotion is disclosed. The contents of various components in the growth agent by mass ratio are: straw 40-72 wt %, polyacrylate 5-12 wt %, diatomaceous earth 6-15 wt %, waste paper 1-5 wt %, zeolite 8-30 wt %, water 10-30 wt %, and additive 0.054-0.135 wt %. The growth agent is prepared by a microwave method. When applied into the soil, the growth agent can quickly absorb and keep rainwater or irrigation water without leakage, thereby ensuring sufficient water in rhizosphere and slow release for use by plants. At the same time, the growth agent has the functions of adsorbing fertilizers such as nitrogen, phosphorus and potassium and retaining the fertilizers in the growth agent for use by plants, thus the loss of nutrients is greatly reduced, and the fertilizer effect is prolonged.

Abstract: The present invention belongs to the field of carbon materials and provides a precursor material and method for the preparation of carbon nanostructures. The invention directly uses rocks or mixtures of carbon raw materials with metal or metal oxide catalysts to prepare precursor materials. The precursor material is then wrapped by using metal wires and polarized in a molten salt system to prepare the nanostructured carbon material. Metals or metal oxides scattered in the carbon phase act as catalysts for the generation of nanostructured carbon materials; this precursor material can be easily obtained from natural rocks or by artificially synthesizing. Nanostructured carbon materials are composed of carbon nanoparticles, carbon fiber and carbon nanotubes. The preparation process is simple and easy to implement, and the resulting nanostructured material has high conductivity and can be used as an active material or additive for use in energy storage devices.
