  • Patent number: 11021584
    Abstract: Microporous sheet product and methods of making and using the same. In one embodiment, the microporous sheet product is made by a process that includes melt-extruding a sheet material using an extrusion mixture that includes a thermoplastic polymer, a superabsorbent polymer, and a compatibilizing agent. After extrusion, the compatibilizing agent may be removed from the sheet material. When the sheet product is imbibed with a polar or ion-containing liquid, the superabsorbent polymer swells, causing a reduction in the pore size of the sheet product. The exposure also causes some of the superabsorbent polymer to migrate to the exterior of the microporous sheet product. The microporous sheet product may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier in the ultrafiltration of colloidal matter, and in disposable garments.

  • Patent number: 10822246
    Abstract: This disclosure provides a unique approach for the synthesis of non-stoichiometric, mesoporous metal oxides with nano-sized crystalline wall. The as-synthesized mesoporous metal oxide is very active and stable (durability >11 h) electocatalyst in both acidic and alkaline conditions. The intrinsic mesoporous metal oxide serves as an electrocatalyst without the assistant of carbon materials, noble metals, or other materials, which are widely used in previously developed systems. The as-synthesized mesoporous metal oxide has large accessible pores (2-50 nm), which are able to facilitate mass transport and charge transfer. The as-synthesized mesoporous metal oxide requires a low overpotential and is oxygen deficient. Oxygen vacancies and mesoporosity served as key factors for excellent performance.

  • Patent number: 9611536
    Abstract: A method of making nanostructures includes following steps. A carbon nanotube structure is suspended, wherein the carbon nanotube structure includes a number of carbon nanotubes orderly aligned. A carbon nanotube composite structure is formed by applying a precoated layer on the carbon nanotube structure, wherein a thickness of the precoated layer on an outer surface of each of the number of carbon nanotubes ranges from about 2 nanometers to about 10 nanometers. The carbon nanotube composite structure is transferred on a substrate and treating the carbon nanotube composite structure with a solution. The carbon nanotube structure is removed by annealing the carbon nanotube composite structure in an annealing temperature from about 500° C. to about 700° C., wherein the precoated layer is softened and contracted.

  • Patent number: 9492351
    Abstract: A liquid transfer connector comprises an enclosure holding a transfer needle and an exhaust needle. A container of donor liquid may be attached to an inlet end of the transfer needle and a container holding a recipient liquid may be attached to an outlet end of the transfer needle and an inlet end of an exhaust needle. The exhaust needle has an outlet end within the connector which releases displaced fluid into an absorbent mass which sequesters the fluid to prevent leakage.

  • Patent number: 9005745
    Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, activated carbon, and water are provided. The activated carbon acts as both a water absorbent and carrier for the water. The activated carbon is able to control and increase cell size even in the presence of carbon dioxide, HFCs, and/or infrared attenuating agents. Additionally, the activated carbon permits a desired amount of water to be introduced into the polymer melt. By controlling the amount of activated carbon and its water content during an extrusion process, a broad range of cell sizes can be obtained in the extruded product. In exemplary embodiments, the activated carbon is added to a primary extruder and water is directly injected into a secondary extruder. Alternatively, the activated carbon is compounded with a polymer resin, pre-hydrated by conditioning or steam impregnation, and added to a primary or secondary extruder.
