摘要： A non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition includes a non-aqueous, non-flammable Group IVB metal alkoxide, wherein the metal is chemically bonded to a glycol containing 4 or more carbons, to an alkoxy group containing 6 or more carbons, or a mixture of both. A fracturing fluid employed in the hydraulic fracturing of subterranean formations is formulated through mixture of the non-aqueous, non-flammable Group IVB metal alkoxide crosslinker composition with a polymer solution.

摘要： A (GaAs-resident) application specific monolithic microwave integrated circuit (ASMMIC) is fabricated through the use of footprints that include a portion of the metallization through which the circuit components within the wafer are to be interconnected. The metallization is a three layers structure, the first two layers of which include strategically arranged reactance circuit components (MIM) capacitors. A first of the three metal layers is formed on a first surface of the substrate which contains a plurality of semiconductor device regions and conductive material for ohmic contact to the regions, so that portions of the first metal layer are in ohmic contact with the conductive material. The first metal layer provides the bottom plate of the MIM capacitors. A dielectric layer, which serves as the dielectric insulator of the MIM capacitors, is formed on second portions of the first metal layer. A second, intermediate metal layer is selectively formed on the second portions of the first metal layer, to provide top plate segments of MIM capacitors. Personalization of the footprint is effected by an air bridge metal layer interconnecting the first and second metal layers and thereby semiconductor device regions of the semiconductor structure with capacitive reactance elements formed by the first and second metal layers.

摘要： Synthetic ester lubricant blends are described which contain 1-90 weight percent of an N-substituted polyoxyalkylene phenothiazine. The polyoxyalkylene group can be derived from ethylene, propylene, butylene or styrene oxides. The blends have superior oxidative and thermal stability and at the same time have good viscosity characteristics and pour points over a wide range of temperatures.
