  • Patent number: 11241678
    Abstract: A method for making organo-metal material involves providing a metal ion source in a medium that removes metal ions from the source and forms 1D metal-containing coordination polymers that self-assemble and precipitate as at least one of a 2D and 3D coordination polymer material that can be thermally treated to produce a porous metal oxide material.
    Type: Grant
    Filed: April 27, 2018
    Date of Patent: February 8, 2022
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Martin M. Thuo, Boyce S. Chang, Jiahao Chen, Aaron J. Rossini
  • Patent number: 11059098
    Abstract: A method of direct printing or writing of a metallic material involves depositing, with a printing device or writing device, an ink comprising of at least undercooled liquid metallic particles dispersed in a carrier fluid. The ink is deposited on any substrate surface to deposit the undercooled liquid metal particles thereon as one or more layers that can form a desired pattern or layered structure.
    Type: Grant

  • 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.

  • Publication number: 20180258235
    Abstract: A composite material is provided including an elastomeric 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: 9682856
    Abstract: MEMS devices fabricated using inexpensive substrate materials such as paper or fabric, are provided. Using paper as a substrate, low cost, simple to prepare, lightweight, disposable piezoresistive sensors, including accelerometers are prepared. Signal-processing circuitry can also be patterned on the substrate material. The sensors can be utilized as two-dimensional sensors, or the paper substrate material can be folded to arrange the sensors in a three dimensional conformation. For example, three sensors can be patterned on a paper substrate and folded into a cube such that the three sensors are orthogonally positioned on the faces of a cube, permitting simultaneous measurement of accelerations along three orthogonal directions (x-y-z). These paper-based sensors can be mass produced by incorporating highly developed technologies for automatic paper cutting, folding, and screen-printing. Also provided are methods of modifying paper for use as a substrate material in MEMS devices.
