摘要： The present invention discloses a copper paste for printing a capillary structure and a preparation method thereof. The copper paste consists of copper powder, a high molecular polymer, a solvent, a binder, a dispersant, a leveling agent, a tackifier and an antioxidant. Through the limitation on the copper powder and the high molecular polymer in the copper paste of the present invention, the prepared copper paste can be applied to a carrier of a vapor chamber by blade coating or screen printing, and then used as a wick after binder removal and sintering in hydrogen or hydrogen-nitrogen mixed gas, so as to reduce device investment and cost; and the thickness of the wick can be accurately controlled to be 10-100 μm, the structural strength is higher, the water absorption performance and the heat transfer performance are better, and the demand for miniaturization of electronic products is met.

摘要： A method for manufacturing a wrought metallic article from metallic-powder compositions comprises steps of (1) compacting the metallic-powder composition to yield a compact, having a surface, a cross-sectional area, and a relative density of less than 100 percent, (2) reducing the cross-sectional area of the compact via an initial forming pass of a rotary incremental forming process so that the compact has a decreased cross-sectional area, and (3) reducing the decreased cross-sectional area of the compact via a subsequent forming pass of the rotary incremental forming process by a greater percentage than that, by which the cross-sectional area of the compact was reduced during the initial forming pass.

摘要： A metal powder for 3D printer includes a plurality of metal particles. A particle size distribution of the plurality of metal particles has a maximum peak within particle diameters of 1 μm to 200 μm. The particle size distribution gives a difference D90−D10 of 10 μm or more between D90 and D10, D90 denoting a particle diameter in which a cumulative percentage is 90% in volume proportion, and D10 denoting a particle diameter in which a cumulative percentage is 10% in volume proportion.

摘要： The given invention is related to the field of medicine, namely to experimental research in oncology, and can be used to obtain a pharmaceutical agent for inhibiting the proliferation of HeLa cervical cancer cells. It entails the use of a metal powder obtained in a gaseous medium by means of an electric explosion of a wire made of low-carbon steel carried out with a specific energy of 7-18 kJ/g and a pulse duration of 1.2-2 μs. The explosion is carried out inside a reactor that is pre-evacuated to a residual pressure of 10−2 Pa, and then filled with carbon monoxide to a pressure of 105 Pa at a gas circulation rate flow of 10 m/s. The products of the explosion deposited in a hopper are passivated in air for at least 48 hours. The resulting powder is extracted and mixed with a solution of the RPMI-1640 nutrient medium with L-glutamine, a pH of 7.2, in the proportion of the mass of the powder to the volume of the specified solution from 1:10 to 2.7:10. The solution is then centrifuged until the phases are separated. The liquid phase is decanted and used as a pharmaceutical agent. The purpose of the given invention is to expand the arsenal of tools for inhibiting the proliferation of tumor cells.
