Metal alloy layers on substrates, methods of making same, and uses thereof

Patent Hu, Liangbing; Wachsman, Eric D.; Gong, Yunhui; ...

Metal alloy layers on substrates. The metal-alloy layers (e.g., lithium-metal layers, sodium-metal layers, and magnesium-metal layers) can be disposed on, for example, a solid-state electrolyte material. The metal-alloy layers can be used in, for example, solid-state batteries. A metal alloy layer can be an anode or part of an anode of a solid state battery.

Super-hydrophobic bandages and method of making the same

Patent Simpson, John T [Clinton, TN]; D'Urso, Brian R [Pittsburgh, PA]

A bandage that includes a material, which can be breathable, having a first surface, and a plurality of superhydrophobic particles attached to the first surface. The plurality of superhydrophobic particles ranging in size from about 100 nanometers to about 10 micrometers. The superhydrophobic particles including a protrusive material defining a plurality of nanopores and a plurality of spaced apart nanostructures that define an external boundary of the hydrophobic particles. The nanopores providing a flow through porosity. The first surface can be rendered superhydrophobic by the attached superhydrophobic particles. The material can have a second surface opposite the first surface thatmore » « less

Ceramic/metal and A15/metal superconducting composite materials exploiting the superconducting proximity effect and method of making the same

Patent Holcomb, Matthew J [Manhattan Beach, CA]

A composite superconducting material made of coated particles of ceramic superconducting material and a metal matrix material. The metal matrix material fills the regions between the coated particles. The coating material is a material that is chemically nonreactive with the ceramic. Preferably, it is silver. The coating serves to chemically insulate the ceramic from the metal matrix material. The metal matrix material is a metal that is susceptible to the superconducting proximity effect. Preferably, it is a NbTi alloy. The metal matrix material is induced to become superconducting by the superconducting proximity effect when the temperature of the material goesmore » « less
