The Japan Institute of Physical Chemistry and Chiba University announced on August 12, 2013 that they have jointly developed a new insulation layer that can reduce the thickness of the insulating layer of rare-earth new generation high-temperature superconducting wires to 1/10 or less. method. Since the insulating layer is thin, the current density of the superconducting coil is increased, and it is expected that miniaturization of the superconducting coil will be achieved. Since the thickness of the original insulating layer is substantially the same as the thickness of the energized layer of the superconducting wire, there is a problem that the coil current density is low. A new generation of high-temperature superconducting wire is in the shape of a thin strip with a width of 4 to 5 mm and a thickness of 100 to 150 μm. To be used as a superconducting coil, the wire must be covered with an insulating material. The method used to form the insulating layer developed by Riken and Chiba University used the “polyimide electrodeposition method†to attach the positively charged polyimide particles to the negatively charged wire rods. Finally, the ribbons were formed. On the wire, the flat part needless to say, the corner part can also be uniformly formed a very thin polyimide insulation film. Compared with the conventional method of winding a polymer tape as an insulating material, the new method not only forms a thin insulating layer, but also does not have to worry about tape breakage and offset, and can easily form the insulating layer in a few steps, and can also be easily used. In several kilometers long wire. The superconducting wire (including the insulating layer) has a cross-sectional area where the ratio of the insulating portion is less than 10% (originally 50% or more), and the current density of the superconducting coil is increased by more than 2 times. In the case of a lead coil, the volume can be reduced to 1/5 or less (in the case of a superconducting coil having an inner diameter of 10 cm and a 10 T magnetic field generated in the center). (Reporter: Yoshida, "Nikkei Manufacturing") Uni®Mab is a high performance Protein A affinity chromatography medium, introduced by Nanomicrotechwithits patented technology developed in-house. This medium is based on the monodisperse porous poly (methyl methacrylate) (PMMA) microspheres as the matrix, and a genetically modified protein A as the ligand, which ensures its high affinity binding of monoclonal antibodies and Fc fragment containing recombinant proteins (macromolecules). Uni®Mab has come with high mechanical strength and good pH stability. Even at a high flow rate, it still maintained a high dynamic binding capacity, meeting the demands from laboratory preparationto industrial production.
