摘要:
A method is provided for fabrication of superconducting oxides and superconducting oxide composites and for joining superconductors to other materials. A coating of a molten alloy containing the metallic elements of the oxide is applied to a substrate surface and oxidized to form the superconducting oxide. A material can be contacted to the molten alloy which is subsequently oxidized joining the material to the resulting superconducting oxide coating. Substrates of varied composition and shape can be coated or joined by this method.

A superconductor oxide composite is prepared using a press coating technique. The coated layers on various substrates exhibit good adhesion, textured microstructure, and improved J.sub.c.
摘要:
The present invention relates to a process comprising the steps of a) contacting an aqueous dispersion of a TiO2 slurry containing adsorbing dispersant with an adsorbing latex to form a mixture, wherein the pH of the mixture of the TiO2 slurry and adsorbing latex are sufficiently high to inhibit interaction between the TiO2 and the adsorbing latex; then b) lowering the pH of the mixture of step a) sufficiently to promote interaction between the TiO2 and the adsorbing latex, thereby forming a composite. The process of the present invention provides for improved hiding and reduced grit for coatings compositions.
摘要:
A process for conversion of conventional sand granules (or other particulates) to a ‘core-shell’ adsorbent granules in which GO (or GO-f) coating imparts nano structural features on the surface of the sand granules (or other particulates). Such materials are useful in a variety of engineering applications such as water purification, catalysis, capacitors, proppants, casting, and magnetic shielding.

Methods, structures, devices and systems are disclosed for fabrication of microtube engines using membrane template electrodeposition. Such nanomotors operate based on bubble-induced propulsion in biological fluids and salt-rich environments. In one aspect, fabricating microengines includes depositing a polymer layer on a membrane template, depositing a conductive metal layer on the polymer layer, and dissolving the membrane template to release the multilayer microtubes.

The present invention relates to patterned graphite oxide films and methods to make and use same. The present invention includes a novel strategy developed to imprint any required conductive patterns onto self-assembled graphene oxide (GO) membranes.
摘要:
A polymer with good compatibility comprising one or more non-ionic water soluble monomers, such as poly(ethylene glycol)(meth)acrylate (PEGMA), is provided that is suitable for use in aerosol hair styling formulations which have improved clarity. There is also provided a hair styling composition comprising (a) one or more fully soluble polymer, and (b) a solvent mixture, and optional other ingredients.
摘要:
A detect method is provided for performing step dimming selection in an electronic ballast including an End of Lamp Life detect circuit and a half-bridge inverter, the End of Lamp Life detect circuit being connected to an input terminal of the control circuit, wherein each time when the power switch is turned on, it is judged whether the electronic ballast should enter the dimming mode or not by detecting the voltage at the input terminal of the control circuit before the half-bridge inverter starts operating.

摘要:
A solution for associating network traffic to enterprise users in a terminal services environment includes, at a network device configured as a terminal server, monitoring outbound network connections. If an outbound network connection is detected, a record is created indicating an association between the network connection and an enterprise user that initiated the network connection. The record is reported to a remote packet monitor which maintains a permanent log of the record. The permanent log may be used for tagging observed network traffic with an owning user.
