  • Method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation
    Patent number: 11980844
    Abstract: The present invention relates to a method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation. In the present invention, multiple means such as multistage circulating absorption, intelligent multi-factor regulation, pre-washing and cooling, inter-stage cooling, post-stage washing, slurry cleaning, cooling water waste heat utilization, small-particle-size and high-density spraying, external strengthening field such as a thermal field/ultrasonic field/electric field, and catalysis by composite catalyst are adopted, so that the target for low cost, low energy consumption, stability and high efficiency is realized. The secondary pollutants are effectively inhibited while carbon dioxide is efficiently captured; meanwhile, high-efficiency capture, low-energy desorption, and high-purity concentration of carbon dioxide are implemented.

  • Spin-orbit torque device, method for fabricating a spin-orbit torque device and method for switching a switchable magnetization of a spin-orbit torque device
    Patent number: 11968842
    Abstract: A spin-orbit torque device is described. The spin-orbit torque device comprising an interfacing layer and a magnetic layer having a switchable magnetization direction. An interface is formed between the interfacing layer and the magnetic layer, the interface having a 3m1 crystallographic point group symmetry adapted to interact with an electric current to generate a spin torque for switching the magnetization direction of the magnetic layer. A method for fabricating the spin-orbit device and a method for switching the switchable magnetization of a spin-orbit torque device are also described.
