Abstract: Cooling devices (i.e., refrigerators or heat pumps) based on polymers which exhibit a temperature change upon application or removal of an electrical field or voltage, (e.g., fluoropolymers or crosslinked fluoropolymers that exhibit electrocaloric effect).

Abstract: Pressure-sensitive adhesives that minimize and/or resist plasticizer migration, pressure-sensitive adhesive articles with such pressure-sensitive adhesives, and methods for fabricating such pressure-sensitive adhesives are provided. In an embodiment, a pressure-sensitive adhesive includes a wax chosen from ethylene-acrylic acid copolymer, ethylene-vinyl acetate, or mixtures thereof. The pressure-sensitive adhesive also contains a natural rubber, a synthetic rubber, a tackifier, and a solvent.

Abstract: The present invention provides a security functional thin film and a security product containing such a thin film. The security functional thin film is of an amorphous structure, and possesses soft magnetic characteristics. Large Barkhausen effect can be detected along the in-plane preferred direction of magnetization; and the Large Barkhausen effect significantly attenuates, or no such signal can be detected, in a direction perpendicular to the in-plane preferred direction of magnetization. The thin film has a thickness of 20-300 nm, and the thin film also possesses element encoding characteristics that can be authenticated by experts. The security functional thin film of the present invention can be fabricated by magnetron sputtering web coating process.

Abstract: The present invention discloses a detachable lampshade comprising an upper supporting hoop with a plurality of radial ribs, a lower supporting hoop with a plurality of locating pieces, and the translucent covering, and the upper and lower supporting hoops are secured to both ends of the translucent covering respectively, and there is a plurality of supporting mounts in between the upper and lower supporting hoops; the lower ends of the supporting mounts are fixed in between the locating pieces and the translucent covering; wherein there is an inner flange on the bottom surface and near the periphery of the upper supporting hoop, and the upper ends of the supporting mounts are fixed in between the inner flange and the translucent covering. The present invention provides a detachable lampshade which is of simpler construction and lower cost of manufacture and is easier to be disassembled and reassembled.

Abstract: The present invention generally relates to chemical, biological, and/or biochemical reactor chips and other reaction systems such as microreactor systems, as well as systems and methods for constructing and using such devices. In one aspect, a chip or other reaction system may be constructed so as to promote cell growth within it. In certain embodiments, the chips or other reaction systems of the invention include one or more reaction sites. The reaction sites can be very small, for example, with a volume of less than about 1 ml. In one aspect of the invention, a chip is able to detect, measure and/or control an environmental factor such as the temperature, pressure, CO2 concentration, O2 concentration, relative humidity, pH, etc. associated with one or more reaction sites, by using one or more sensors, actuators, processors, and/or control systems. In another aspect, the present invention is directed to materials and systems having humidity and/or gas control, for example, for use with a chip.
