A process for metalizing a ceramic surface or attaching a ceramic to a metal is provided. The process may comprise: immersing the ceramic into an aluminum or aluminum alloy melt, making the ceramic move or stay still relative to the melt to adhere the melt to the ceramic; and then removing the ceramic from the melt to unaffectedly cool the film adhered thereto. The process can attach an aluminum or aluminum alloy thin film having a thickness of several to tens of micrometers on a ceramic surface. The thin film is formed by solidification, and does not have microscopic faults such as oxide film inclusions or pores, therefore having proper physical of mechanical properties of aluminum. Ceramics or a ceramic and a metal can be brazed via the surface metalizing film, the bonding strength of their interface can over the strength of aluminum itself.This invention discloses a process for metalizing the surface of a ceramic and a process for attaching a ceramic to a metal. A process for attaching an aluminum or aluminum alloy thin film to a ceramic surface comprises the steps of: immersing a ceramic surface to be metalized into a aluminum or aluminum alloy melt, and making the ceramic move or stay still relative to the melt to adhere the melt of the aluminum or aluminum alloy to the metalizing surface of the ceramic; and then removing the metalizing surface of the ceramic from the melt to unaffectedly cool the aluminum or aluminum alloy liquid film adhered thereto to obtain a ceramic having the aluminum or aluminum alloy thin film attached to the surface. The process to attaching aluminum or aluminum alloy thin film on the surface of a ceramic of the present invention can attach an aluminum or aluminum alloy thin film having a thickness of several micrometers to tens of micrometers on the surface of a ceramic. The thin film is formed by the solidification of the aluminum of aluminum alloy liquid film attached on the surface of a ceramic, and it does not have the microscopic faults such as oxide film inclusions or pores, therefore having the proper physical of mechanical properties of aluminum. Ceramics or a ceramic and a metal can be brazed via the surface metalizing film, the bonding strength of their interface can over the strength of aluminum itself.

The invention relates to a composite carbon diaphragm with a mesoporous and microporous gradient structure and a preparation method for the diaphragm. The composite carbon diaphragm with the mesoporous and microporous gradient structure consists of a porous support body, a mesoporous intermediate layer and a surface separation layer, and is characterized in that the pore diameter of the porous support body is 100 to 500 nanometers, the breaking strength is 2 to 15MPa, and the anti-explosion strength is 3 to 10MPa; the pore diameter of the mesoporous intermediate layer is 2 to 10 nanometers, the specific surface area is 400 to 1,000 m<2> / g, the porosity is 30 to 50 percent, and the thickness is 1 to 10 micrometers; and the pore diameter of the surface separation layer is 0.3 to 0.5 nanometer, the specific surface area is 300 to 600 m<2> / g, the porosity is 20 to 40 percent, and the thickness is 0.1 to 5 micrometers. By the composite carbon diaphragm with the mesoporous and microporous gradient structure, the phenomenon that the gas separation performance of the composite carbon diaphragm is greatly reduced due to the defect of the surface of the support body is avoided, and the permeability of the prepared composite carbon diaphragm is improved obviously on the basis of keeping high gas separation selectivity.

The aim of the invention is to provide a high fidelity nanometer flow sensor based on the field effect tube which can magnify the microscopic variations of conductivity of medium into the drain current fluctuation of the field effect tube.

Disclosed is a thermal dye-transfer dye-image receiving element comprising a thermal dye-transfer receiver element comprising a dye-receiving layer 1; beneath layer 1, a substrate layer 2 containing a microvoided layer 2 comprising, in a continuous phase, a polylactic-acid-based material, wherein microvoids in said microvoided layer provide a void volume of at least 25% by volume, and wherein at least about half of the microvoids are formed from void initiating particles less than 1.5 micrometer in average diameter; and beneath layer 2, an optional support layer 3.

The invention relates to the technical field of medicines, in particular to application of cirsimaritin in preparing an antiviral drug. The invention for the first time proposes that the cirsimaritin has definite resistance to an influenza virus. The cirsimaritin can significantly inhibit a cytopathic effect caused by the influenza virus infection, and median inhibitory concentrations to an influenza virus A / FortMonmouth / 1 / 1947 and an influenza virus A / jinnan / 15 / 2009 are equivalent to that of an influenza virus Amantadine and an influenza virus Ribavirin; meanwhile, the cirsimaritin can significantly inhibit the expression of influenza virus specific protein M2 protein, and lower an expression level of influenza virus RNA; the intensities of inhibition functions of 40 microgrammes per milliliter of the cirsimaritin on expression of the influenza virus M2 protein and expression of the influenza virus RNA are equivalent to that of 10 micrometers of the Ribavirin, showing that intensity of the anti-influenza virus effect of the cirsimaritin is close to that of antiviral drugs currently commonly used in clinic, and application of the cirsimaritin in preparing anti-influenza drugs has a good prospect.
