Abstract:
Pure saponins and processes for making such saponins are described herein. In addition, cosmetic compositions, such as skin care compositions, comprising such saponins and methods for improving skin health and appearance with such skincare compositions are also described herein.
Abstract:
A composite comprising an inorganic substrate with a coating comprising activated carbon and a metal sulfide. The composite may be used, for example, for the removal of a contaminant, such as mercury, from a fluid stream.
Abstract:
A method for the sorption of a liquid or vapor phase trace contaminant from a fluid stream containing an electrically charged particulate, which comprises: providing a fluid stream comprising a liquid or vapor phase trace contaminant and an electrically charged particulate; providing an electrically conductive stationary sorbent having an electrical charge that is of the same polarity as that of the charged particulate; and contacting the fluid stream with the charged stationary sorbent, which sorbs the trace contaminant and repels the charged particulate.
Abstract:
A method for managing the use of flow-through monolithic sorbents (408,410,414) for the sorption of a trace contaminant from a fluid stream, which comprises: providing two or more flow-through monolithic sorbents (408,410) having a trace contaminant sorbed thereon, wherein the flow-through monolithic sorbents are positioned in an initial series to allow for passing a fluid stream from an upstream inlet end of the series to a downstream outlet end of the series; removing an inlet end portion (408) of the flow-through monolithic sorbents from the inlet end position of the series; moving a downstream portion (410) of the flow-through monolithic sorbents from a downstream position in the series to the inlet end position of the series; and placing a replacement flow-through monolithic sorbent (414) portion in a downstream position of the series.
Abstract:
An amorphous silica hybrid membrane structure comprising a monolithic inorganic porous support, optionally one or more porous inorganic intermediate layers, and an amorphous silica membrane. The amorphous silica hybrid membrane is useful for gas separation applications, for example H 2 purification and CO 2 capture.
Abstract:
A method of cutting a solid material using a pulsed laser includes providing a pulsed laser beam, selecting a target point in the solid material, focusing the pulsed laser beam on the solid material such that at the target point in the solid material the pulsed laser beam has at least the minimum energy density required to ablate the solid material, and effecting relative motion of the pulsed laser beam with respect to the solid material such that the pulsed laser beam traces a first path to form a scribe line in the solid material and then a second path to form a second scribe line in the solid material, wherein the first path and the second path are essentially parallel and the first and second scribe lines overlap to form a single cut line in the solid material.
Abstract:
A sorbent body adapted for abating toxic elements from a fluid stream, such as a carbon combustion flue gas stream or a syngas stream produced in coal gasification process, and process for making such sorbent. The sorbent body comprises an activated carbon matrix defining a plurality of pores, sulfur and and additive adapated for promoting the abatement of toxic elements from the fluid stream. The sorbent is useful for abatement of, e.g., arsenic, cadmium, mercury and selenium from gas streams.
Abstract:
Carbon materials and methods of manufacturing carbon materials for use in high energy devices, such as electric double layer capacitors are described. High energy devices manufactured with carbon materials contemplated herein have high energy density. Methods of manufacturing carbon materials generally include providing a carbon precursor and an additive, mixing the additive with the carbon precursor prior to curing the carbon precursor, carbonizing the carbon precursor and removing the additive to form the carbon material. Such carbon materials can be used in electric double layer capacitors.
