Patent number: 12194429Abstract: Described are methods and devices for the generation of hydrogel particles with micrometer and submicrometer dimensions using oxygen-inhibited partial polymerization, and the particles generated therefrom. The described methods generate particles with dimensions independent of the starting polymerizable solution dimension, for example, a microdroplet. Further, microfluidic flow parameters (e.g. viscosity, flow rate) and photopolymerization process parameters (e.g. optical exposure intensity and duration) are controlled to generate particles with tunable crosslinking density-determined properties including elasticity, diffusivity, and biomolecular display for diverse applications such as drug delivery, tissue engineering cell scaffolds, and single- and multiple-cell therapeutics. Similarly, gradients of crosslinking density-determined properties can be created within single particles through the selection of optical exposure intensity and duration.Type: GrantFiled: March 15, 2023Date of Patent: January 14, 2025Assignee: University of WyomingInventors: John Oakey, Katie Dongmei Li-Oakey, Daniel Debroy, Carl Frick, Rajib Shaha

Publication number: 20220363547Abstract: A metal-assisted microwave treatment that converting raw coal powders into nano-graphite is presented. Specifically, four major factors are identified for successful conversion: (1) high temperature; (2) reducing environment; (3) catalyst; and (4) microwave radiation. Specifically, it is determined that the combination of the carbon sources (raw coal powders), the high temperature (microwave induced electric sparking), the reducing environment (the Ar/H2 mixture), the catalyst (Cu foil), with the microwave radiations can generate nano-graphite. This novel approach utilizes the sparking induced by the microwave radiation on the fork-shape metal foils to generate high temperature (>1000° C.) within few seconds. The small thermal load makes this method cost effective and has potential for higher temperature using metals with higher melting temperature. Refinement of this technique is possible to yield a higher quality and quantity of nano-graphite materials for a wider range of applications.Type: ApplicationFiled: May 16, 2022Publication date: November 17, 2022Applicants: University of Wyoming, University of WyomingInventor: TeYu Chien
