  • Publication number: 20220072466
    Abstract: An impact test apparatus can be used to determine particle interfacial energies with varying relative air humidity. It was observed that capillary condensation increased the adhesive forces of hydrophilic materials. A systems humidity separation window was identified and the differences in interfacial energy for a hydrophilic surface and for a hydrophobic surface can be exploited in order to achieve the separation of particles. Separation and concentration of particles, particularly particles within a mineral ore body, can be obtained.

  • Publication number: 20220059823
    Abstract: The present disclosure relates to mixed ionically and electronically conducting solid-state phases for their application in electrochemical devices, such as lithium-metal or lithium ion batteries. The solid-state mixed phase comprises of active cathode and carbon-based structures functionalized by a heteropolyacid (HPA) or a metal salt of a heteropolyacid (Me-HPA) to form a solid-state architecture with incorporated ceramic or glass-ceramic electrolyte for enhanced ionic and electronic conductivity pathways. Combining the solid-state phase components in melted solid-state electrolyte results in perfect distribution, improved adhesion between particles, and improved characteristics of the electrochemical device, such as high charge rates, long-term performance, and broad voltage window.

  • Publication number: 20220032245
    Abstract: An improved a device and method for dispersion and simultaneous orientation of nanoparticles within a matrix is provided. A mixer having a shaft and a stator is provided. The shaft may have a rupture region and erosion region. Further, an orienter having an angled stationary plate and a moving plate are provided. The nanoparticles and the matrix are fed into the mixer. A rotational force is applied to the shaft to produce shearing forces. The shearing forces disperse and exfoliate the nanoparticles within the matrix. The dispersed mixture is outputted onto the moving plate. The moving plate is forced across the angled stationary plate to produce fully developed laminar shear flow. The fully developed laminar shear flow or the two-dimensional extensional drag flow orients the dispersed nanoparticles-matrix mixture.

  • Publication number: 20210363649
    Abstract: The present invention relates to a one-step process for preparation of “in-situ” or “ex-situ” self-organized and electrically conducting polymer nanocomposites using thermally initiated polymerization of a halogenated 3,4-ethylenedioxythiophene monomer or its derivatives. This approach does not require additional polymerization initiators or catalysts, produce gaseous products that are naturally removed without affecting the polymer matrix, and do not leave by-product contaminants. It is demonstrated that self-polymerization of halogenated 3,4-ethylenedioxythiophene monomer is not affected by the presence of a solid-state phase in the form of nanoparticles and results in formation of 3,4-polyethylenedioxythiophene (PEDOT) nanocomposites.
