  • Patent number: 11217371
    Abstract: A bulk permanent magnetic material may include between about 5 volume percent and about 40 volume percent Fe16N2 phase domains, a plurality of nonmagnetic atoms or molecules forming domain wall pinning sites, and a balance soft magnetic material, wherein at least some of the soft magnetic material is magnetically coupled to the Fe16N2 phase domains via exchange spring coupling. In some examples, a bulk permanent magnetic material may be formed by implanting N+ ions in an iron workpiece using ion implantation to form an iron nitride workpiece, pre-annealing the iron nitride workpiece to attach the iron nitride workpiece to a substrate, and post-annealing the iron nitride workpiece to form Fe16N2 phase domains within the iron nitride workpiece.

  • Patent number: 11217370
    Abstract: A permanent magnet may include a Fe16N2 phase in a strained state. In some examples, strain may be preserved within the permanent magnet by a technique that includes etching an iron nitride-containing workpiece including Fe16N2 to introduce texture, straining the workpiece, and annealing the workpiece. In some examples, strain may be preserved within the permanent magnet by a technique that includes applying at a first temperature a layer of material to an iron nitride-containing workpiece including Fe16N2, and bringing the layer of material and the iron nitride-containing workpiece to a second temperature, where the material has a different coefficient of thermal expansion than the iron nitride-containing workpiece.

    Abstract: A device for moving film-supported materials and removing the film at a process station includes a first base, a feeding tray, a driving member, a second base, a moving member, and a laser sensor. The feeding and stripping automatically conveys a raw material assembly. A gap exists between the second base and the first base, and only raw materials are passed over the gap. The raw material assembly comprises a base layer and a number of raw materials disposed on the base layer. The gap allows the raw material disposed on a bent portion of the base layer to separate from the base layer while the base layer itself is gathered to another destination.

  • Publication number: 20210317232
    Abstract: Increasingly, human subjects are taking biotin as a medical therapy or nutritional supplement. This practice causes difficulty in analysis of biological samples, such as blood samples, using biotin conjugate reagents since free biotin results in interference. Inventive antibodies, and antigen binding fragments thereof, which specifically bind to biotin of a biotin conjugate and which have a higher affinity for biotin of a biotin conjugate than for free biotin, are provided along with methods of their use.
