  • Patent number: 10766831
    Abstract: A method for gas atomization of oxygen-reactive reactive metals and alloys wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a protective reaction film on the atomized particles. The present invention is especially useful for making highly pyrophoric reactive metal or alloy atomized powders, such as atomized magnesium and magnesium alloy powders. The gaseous reactive species (agents) are introduced into the atomization spray chamber at locations downstream of a gas atomizing nozzle as determined by the desired powder or particle temperature for the reactions and the desired thickness of the reaction film.

  • Patent number: 10758984
    Abstract: A physical and chemical method is provided for de-mixing (e.g. extracting, separating, purifying and/or enriching) the metal constituents of an alloy or mixed material into different droplet or solid particle products that are highly enriched in the respective phases of the metal. The method involves for instance but is not limited to, shearing, separating and segregating metallic droplets and particles in a carrier fluid to form other droplets or particles that are each separately highly enriched in one of some, if not of all, of the constituent phases of the alloy or mixed material.

  • Patent number: 10759127
    Abstract: A composite material is provided including a polymer matrix and undercooled liquid metallic core-shell particles disposed in the matrix, wherein the particles each have an outer shell and a liquid metallic material as a core contained within the outer shell. The outer shell is frangible such that the liquid metallic material is released from at least some of the particles in response to a mechanical load applied to the composite and solidifies in-situ in the polymer matrix. As a result, the composite material can be self-strengthening and self-healing and can be reconfigurable in shape at ambient temperature.

  • Patent number: 10725373
    Abstract: A technique, and its applications, for high resolution, rapid, and simple nanopatterning. The general method has been demonstrated in several forms and applications. One is patterning nanophotonic structures at an optical fiber tip for refractive index sensing. Another is patterning nanoresonator structures on a sensor substrate for plasmonic effect related detection of VOCs. In the latter example, a graphene oxide coated plasmonic crystal as a gas sensor capable of identifying different gas species using an array of such structures. By coating the surface of multiple identical plasmonic crystals with different thicknesses of Graphene-Oxide (GO) layer, the effective refractive index of the GO layer on each plasmonic crystal is differently modulated when exposed to a specific gas. Identification of various gas species is accomplished using pattern recognition algorithm.

  • Publication number: 20200192969
    Abstract: Disclosed herein are embodiments of methods for encoding, decoding, and matching patterns in collections of signals. These methods use weighting functions to scale the signals. This scaling enables the use of signals of arbitrary duration, wherein the signals may include discrete sequences and spike trains. In the most general case, the signals can be represented using functionals, which extends the expressive power of the methods. Further disclosed herein are embodiments of a system that performs these methods.

  • Publication number: 20200159808
    Abstract: Embodiments of the present disclosure describe an efficient O(n log n) method that implements the Inverse Chirp Z-Transform (ICZT). This transform is the inverse of the well-known forward Chirp Z-Transform (CZT), which generalizes the fast Fourier transform (FFT) by allowing the sampling points to fall on a logarithmic spiral contour instead of the unit circle. Thus, the ICZT can be viewed as a generalization of the inverse fast Fourier transform (IFFT).
