摘要:
Embodiments include curable compositions including an epoxy resin and a hardener component including a terpolymer having first constitutional unit, a second constitutional unit, and a third constitutional unit, where the epoxy group to the second constitutional unit has a molar ratio in a range of 1.0:1.0 to 2.7:1.0. Embodiments include prepregs that include a reinforcement component and the curable composition and an electrical laminate formed with the curable composition.
摘要:
A novel nickel-carbon electrode, and methods for making the same, have been developed. The nickel-carbon electrode comprises an active mass (e.g., a nickel oxyhydroxide, hydroxide or oxide) deposited to a carbon foam using any one of chemical deposition, thermal deposition or electrochemical deposition. The nickel-carbon electrode is formed or “activated” through a series of charge-discharge cycles. The nickel-carbon electrode is comparable in volumetric capacities (mAh/cc) with commercial nickel electrodes but higher in gravimetric capacities (mAh/g). The nickel-carbon electrode may be used in rechargeable nickel-based batteries which have applications in cordless appliances, portable devices, standby power systems, the aerospace industry, and hybrid electric vehicles.
摘要:
A cover for obstructing the camera of an optical head mounted display is provided. The cover comprises a sleeve having a cavity adapted to slide over an optical head mounted display camera. The sleeve removably attaches to the optical head mounted display camera via snap connectors located within the cavity of the sleeve. The sleeve is sufficiently flexible to accept insertion of the optical head mounted display camera and securely retain the optical head mounted display camera therein. The cover further includes an indicator on an exterior surface thereof designating that the optical head mounted display camera is not operational.

The invention relates to a method, apparatus and system for the treatment of organic and inorganic waste in a waste fluid. The method involves a co-current plug flow of fluid in a reactor in which ozone mass transfer conforms to the effective life of the ozone used in the treatment. Hydroxide and hydrogen peroxide can be added to the waste fluid. The combined fluids to be treated travel the reactor through a series of surfaces in a packed reactor. The apparatus includes a diffuser for ozone which assists in the co-current plug flow of fluids. The diffuser can have a porosity of about 10 microns. The invention further envisions a compact system for efficient treatment of waste fluids.
