Abstract: Disclosed are WC/CNT, WC/CNT/Pt composite material and preparation process therefor and use thereof. The WC/CNT/Pt composite material comprises mesoporous spherical tungsten carbide with diameter of 1-5 microns, carbon nanotubes and platinum nanoparticles, with the carbon nanotubes growing on the surface of the mesoporous spherical tungsten carbide and expanding outward, and the platinum nanoparticles growing on the surfaces of the mesoporous spherical tungsten carbide and carbon nanotubes. The WC/CNT composite material comprises mesoporous spherical tungsten carbide with diameter of 1-5 microns, and carbon nanotubes growing on the surface of the mesoporous spherical tungsten carbide and expanding outward. The WC/CNT/Pt composite material can be used as an electro-catalyst in a methanol flue battery, significantly improving the catalytic conversion rate and the service life of the catalyst.

Abstract: An electrode for effective ozone production in an electrochemical cell uses a modified electrode design which adopts a novel catalytic component. The catalytic component has a number of elements selected from various metals and metalloids, and is applied to a substrate in multiple coatings or layers. The catalytic component forms a catalytic surface which is at least partially disrupted by the presence of an element which is relatively inactive with respect to oxygen evolution.

Abstract: A dehumidification and energy recovery device includes a casing defining an interior that is divided into two vertically stacked sections, a channel extending vertically between the sections and forming upper and lower openings, absorption devices arranged inside the channel corresponding to the sections respectively, and a tank arranged below the lower opening of the channel and containing a liquid that is driven by a pump to a position above the upper opening of the channel to drop onto and flow through the absorption devices. Intake airflow and exhaust airflow respectively pass through the sections, contacting the liquid flowing through the channel in a cross-flow fashion, whereby exchange of humidity and heat is performed between the airflows and the liquid to effect dehumidification and energy recovery with a simple structure and low costs.

Abstract: A dehumidifying device includes a casing that is divided into a dehumidification section and a regeneration section. A moisture-absorptive device made of fibrous material and pre-impregnated with liquid moisture-absorptive agent, is arranged inside the casing and extending between the dehumidification section and the regeneration section. A heater is disposed in an inlet port of regeneration section. When a wet airflow traveling along the dehumidification section passes through the moisture-absorptive device, the moisture is absorbed by the moisture-absorptive device and then spread into the regeneration section due to siphon effect caused by surface tension induced on the fibrous material. The moisture is then removed by an airflow traveling along the regeneration section and heated by the heater to complete the dehumidification operation.

Abstract: A mocha coffee maker is composed of a lower pot, a funnel, a rubber ring, a filter and an upper pot. The filter and the rubber ring are assembled to the bottom of the upper pot, which is provided with interior threads, while the top end of the lower pot is provided with exterior threads, such that after placing the funnel on the lower pot, the upper pot will be fastened to the lower pot via threads. The funnel has a basin of an appropriate height. The basin has a hole at the central bottom. An expanded flange is provided at the outer rim of the basin, while a siphon extends from the bottom hole of the basin for releasing steamer. When the upper pot and the lower pot are screwed together, the outer film of the coffee pack/tea bag will be pressed thereby to easy coffee/tea making.

Abstract: A display adjustment device and method of control thereof are disclosed. The display adjustment device comprises a selector, a resistor set, and an AC/DC (alternate current/direct current) converter. The selector generates a logic pattern in accordance with a first control signal and a second control signal. The resistor set provides an input resistance in accordance with the logic pattern. The AC/DC converter adjusts control of the display in accordance with the input resistance.
