Patent number: 11819953Abstract: A method of using an amalgamation preform includes providing mating bonding surfaces and placing a particle-liquid mixture corresponding to the amalgamation preform between the mating bonding surfaces. The particle-liquid mixture contains a plurality of types of solid particles and a base metal in a liquid form, and the plurality of types of solid particles at least includes reactive particles reactable with the base metal and non-reactive magnetic particles. A first magnetic field is applied to the particle-liquid mixture to magnetically disperse the plurality of types of solid particles in the liquid base metal to form a particle-liquid dispersion; and a second magnetic field is applied to cure the particle-liquid dispersion to allow reactions between the reactive particles and the base metal.Type: GrantFiled: July 1, 2021Date of Patent: November 21, 2023Assignee: MESOGLUE, INCInventors: Stephen P.

The plurality of types of solid particles at least includes reactive particles, reactable with the base metal, and non-reactive magnetic particles. A magnetic field is applied to the particle-liquid mixture to magnetically disperse the plurality of types of solid particles in the liquid base metal to form a particle-liquid dispersion without substantially inducing a reaction between the reactive particles and the liquid base metal. A playdough-like amalgamation preform is prepared based on the particle-liquid dispersion without solidifying the liquid base metal.Type: GrantFiled: July 1, 2021Date of Patent: November 14, 2023Assignee: MESOGLUE, INC.Inventors: Stephen P.

Publication number: 20230078848Abstract: Carbon nanostructures are synthesized from a feedstock that includes polyethylene terephthalate. In a first furnace, the feedstock that includes polyethylene terephthalate and calcium oxide (CaO) or calcium hydroxide (Ca(OH)2) are pyrolyzed to obtain one or more gaseous decomposition products. The gaseous decomposition productions are optionally filtered to remove any solid particles. The one or more gaseous decomposition products are passed across a stainless steel substrate in a second furnace to form the carbon nanostructures.Type: ApplicationFiled: February 19, 2021Publication date: March 16, 2023Inventors: Yiannis A. Levendis, Aidin Panahi, Chuanwei Zhuo

Publication number: 20160367971Abstract: Methods for activating the surface of steel alloys to produce catalytic substrates for the synthesis of carbon nanomaterials by chemical vapor deposition are provided. Steel alloy substrates in a variety of forms are activated by brief (10 sec to 30 min) pre-treatment at high temperature (600-1000° C.) in an oxidizing environment (e.g., air) to activate the catalyst. Upon high temperature oxidative treatment, the initially smooth and protective chromium oxide coating layer of the steel alloy is destroyed, and the catalyst surface roughness progressively increases. Upon exposure of the pre-treated SS substrates to pyrolyzed hydrocarbon gases in nitrogen, carbon nanotubes are readily formed, and their diameters correlate with substrate surface roughness. Forests of vertically aligned nanotubes can be prepared with the method.Type: ApplicationFiled: July 30, 2014Publication date: December 22, 2016Inventors: Chuanwei Zhuo, Yiannis Levendis
