  • Publication number: 20190115202
    Abstract: An opposed dipole magnet assembly is provided that exhibits higher magnetic field uniformity than traditional magnet assemblies, such as H-shaped magnet assemblies. The opposed dipole magnet assembly includes two permanent magnets that are spaced apart and oriented such that their respective magnetization directions are parallel. Plates formed of a high permeability material are attached to top and bottom surfaces of the two permanent magnets so as to form a hollow field region. With this geometry, the magnetic field in the hollow field region is in a direction antiparallel to the magnetic field directions of the two permanent magnets.

  • Patent number: 9603810
    Abstract: The present invention provides for photonic nanoimprinted silk fibroin-based materials and methods for making same, comprising embossing silk fibroin-based films with photonic nanometer scale patterns. In addition, the invention provides for processes by which the silk fibroin-based films can be nanoimprinted at room temperature, by locally decreasing the glass transition temperature of the silk film. Such nanoimprinting process increases high throughput and improves potential for incorporation of silk-based photonics into biomedical and other optical devices.
    Type: Grant
