Abstract: A composition of a sintered superhard compact is provided. The sintered superhard compact body may comprise superhard particles, such as cubic boron nitride. The binder phase may bond the superhard particles together. The binder phase comprises a titanium compound and a balance aluminum compound. The titanium compound may be formed during the high pressure high temperature condition. The sintered superhard compact body may have an amount of the titanium compound in order to have a mixed wear and toughness application.

Abstract: Particulate compositions are described comprising an intimate mixture of a biomass, such as switchgrass or hybrid poplar, a non-biomass carbonaceous material, such as petroleum coke or coal, and a gasification catalyst, where the gasification catalyst is loaded onto at least one of the biomass or non-biomass for gasification in the presence of steam to yield a plurality of gases including methane and at least one or more of hydrogen, carbon monoxide, and other higher hydrocarbons are formed. Processes are also provided for the preparation of the particulate compositions and converting the particulate composition into a plurality of gaseous products.

Abstract: Particulate compositions are described comprising a carbonaceous material, such as petroleum coke and/or coal, treated or otherwise associated with a gasification catalyst, where the catalyst is at least in part derived from a leachate from a biomass char, for gasification in the presence of steam to yield a plurality of gases including methane and at least one or more of hydrogen, carbon monoxide, and other higher hydrocarbons are formed. Processes are also provided for the preparation of the particulate compositions and converting the particulate composition into a plurality of gaseous products.

Abstract: The present invention provides methods, apparatus, and systems for cleaning a substrate that include a controller and a nozzle coupled to the controller. The controller is adapted to direct the nozzle to dispense a uniform fluid spray pattern onto a substrate. The controller is adapted create the uniform fluid spray pattern by adjusting at least one operational parameter of the nozzle to cause a predefined percentage of droplets to be within a predetermined size range. Numerous other aspects are disclosed.

Abstract: An apparatus for redirecting energy applied to a susceptor of a substrate process chamber. Specifically, a shield comprising one or more reflector members is disposed below said susceptor whereby thermal energy radiated from a backside of said susceptor is reflected back to the susceptor. The apparatus comprises a bracket member attached to the reflector members and a pedestal assembly disposed below said susceptor. The reflector members are fabricated from a low emissivity material such as stainless steel (which can be polished to a highly reflective condition). Also, the first and second reflector members can be annealed.
