摘要:
A free standing film includes: i. a matrix layer having opposing surfaces, and ii. an array of nanorods, where the nanorods are oriented to pass through the matrix layer and protrude an average distance of at least 1 micrometer through one or both surfaces of the matrix layer. A method for preparing the free standing film includes (a) providing an array of nanorods on a substrate, optionally (b) infiltrating the array with a sacrificial layer, (c) infiltrating the array with a matrix layer, thereby producing an infiltrated array, optionally (d) removing the sacrificial layer without removing the matrix layer, when step (b) is present, and (e) removing the infiltrated array from the substrate to form the free standing film. The free standing film is useful as an optical filter, ACF, or TIM, depending on the type and density of nanorods selected.
摘要:
A method of preparing a silicone resin film comprising coating a release liner with a nanomaterial-filled silicone composition comprising (i) a free radical-curable silicone composition comprising a silicone resin and (ii) a carbon nanomaterial, and curing the silicone resin of the coated release liner; a silicone resin film prepared according to the preceding method; and a nanomaterial-filled silicone composition.

摘要:
This invention generally relates to computer systems and architectures, methods and computer program code for increasing the robustness of process control and manufacturing automation systems and the like, in particular to provide improved handling of error and/or failure conditions. We describe an architecture for an OPC Failover system, the architecture comprising: a plurality of OPC servers; at least one OPC client; a computer network linking said OPC servers and said OPC client; and an OPC Failover service coupled to said network and not coupled between said OPC client and said OPC servers, said OPC Failover service being configured to monitor at least one of said OPC servers for an error condition and to redirect network communications of said OPC client from one of said servers to another on detection of said error condition.
摘要:
A process for the recovery of nickel and/or cobalt from an impure nickel, cobalt or mixed nickel/cobalt material including the steps of: a) providing a nickel, cobalt or mixed nickel/cobalt material; and b) contacting the nickel, cobalt or mixed nickel/cobalt material with a feed ammoniacal ammonium carbonate solution and a reductant in a leach step.
摘要:
A medication dispensing apparatus having a manually operable plunger axially shiftable relative to the apparatus housing. The plunger is pullable relative to the housing in a proximal direction to cock the apparatus, and when the plunger is then manually pushed back toward the housing, a piston within a medicine container of the apparatus is shifted to force medication from a needle assembly at the distal end of the apparatus. The medication dispensing apparatus also includes a priming mechanism which is operated by rotating an externally accessible driver portion to prime the apparatus for use, which priming can be performed whether or not the apparatus is in a cocked state.
