Abstract:
Materials and methods for converting brown grease to useful diesel fuel are described. One material is a palladium catalyst on a silicon/carbon support. A method comprises flowing fresh hydrogen over a reaction of diluted brown grease on a palladium/carbon catalyst.
Abstract:
This disclosure describes a new method and device that lead to improved performance (in the areas of energy density, power density, and cycle life) of any sulfur or selenide based including their respective polysulfide/polyselenides battery configurations both for stationary and portable applications. A device capable of converting lower polysulfides/polyselenides to higher polysulfides/polyselenides (and vice versa) and trapping said compounds in a highly porous matrix is described. The device may be rechargeable. Catalytically-active materials such as bulk metal structures, thin films of metals, microporous/nanoporous structures of materials, and carbon composites of metals and their alloys can be used as current collectors, electrodes, or both.
Abstract:
A composite anode for a lithium-ion battery is manufactured from silicon nanoparticles having diameters mostly under 10 nm; providing an oxide layer on the silicon nanoparticles; dispersing the silicon nanoparticles in a polar liquid; providing a graphene oxide suspension; mixing the polar liquid containing the dispersed silicone nanoparticles with the graphene oxide suspension to obtain a composite mixture; probe-sonicating the mixture for a predetermined time; filtering the composite mixture to obtain a solid composite; drying the composite; and reducing the composite to obtain graphene and silicon.
