Abstract: The invention presents a method for predicting volatile organic compounds (VOCs) adsorption capacity via filling adsorption, in the domain of exhaust gas treatment. Utilizing two or more porous materials with concentrated pore size distributions as model adsorption materials, it identifies the critical pore size for filling adsorption under specific conditions. Filling adsorption operates via volume filling, linking adsorption capacity to density and pore volume. Conversely, non-filling adsorption relies on surface covering mechanisms, correlating adsorption capacity with specific surface area. By establishing a linear equation using pore volume and specific surface area, solved with known model material parameters, it accommodates pore size variation and pressure influence on adsorption capacity. This equation predicts VOCs adsorption capacity and isotherms based on the adsorption material's pore structure.

Abstract: A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.

Abstract: The present disclosure provides a method and system for improving a counting rate of a superconducting nanowire single photon detector. The method includes: coupling an electrical attenuator in series with an output end of the superconducting nanowire single photon detector; the electrical attenuator includes an input end and an output end, and the input end of the electrical attenuator is coupled with the output end of the superconducting nanowire single photon detector. The present disclosure couples the electrical attenuator in series with the output end of the superconducting nanowire single photon detector. Since the configuration of the electrical attenuator is a resistor network, it can act as a series resistor and can also reduce the response pulse amplitude of the superconducting nanowire single photon detector. The present disclosure can improve the counting rate of the superconducting nanowire single photon detector, while keeping the detection efficiency high.

Abstract: The present invention is a method for distinguishing, classifying and measuring soft and hard inclusions in a liquid metal that includes obtaining a flow through cell disposed on a tube with a top to allow the liquid metal to flow through the flow through cell and into the tube. There is also a mounting and a vacuum system disposed on top of the tube to draw the liquid metal through the flow through cell and into the tube that utilizes a pair of electrodes set inside and outside of the tube to apply an electric current to the liquid metal passing through the flow through cell. An electric resistance change is then measured and an electric resistance pulse is applied to the liquid metal to measure deformed behavior of the inclusions. The resistance pulse method can be used with liquid droplets, steel slag, bubbles and other deformable inclusions.
