This invention is for an innovative magnetic air separator (MAS) for delivering oxygen-enriched air or near-pure oxygen to for advanced combustion, coal gasification, industrial processes, and medical applications. In the MAS of the subject invention, input air is drawn into a large array of microchannels immersed in a strong, spatially varying magnetic field. Magnetic forces accelerate the paramagnetic O2 molecules within the microchannel flow and in a direction perpendicular to it, thus forming enriched and depleted streams. Such streams are then physically separated and subsequently combined according to their level of O2 enrichment or depletion. Highly enriched streams are repeatedly subjected to the magnetic separation process until the targeted level of O2 concentration is reached in selected streams. Partially enriched streams are recycled and fed back into the process feedstock air, while depleted streams are vented from the process.

By using the recyclable and degradable epoxy resin curing agent of a specific molecular structure, the shear strength of the conductive adhesive is greatly increased, and the reliability and the service life of the conductive adhesive are largely improved.

A mild, acid- and alkali-free purification method of detonation nanodiamond material from water-insoluble metal-containing impurities and product obtained thereof. The products thus obtained include nanodiamond and diamond-containing detonation blend. The method is implemented by an impact treatment of the detonation nanodiamond material with aqueous or water organic solutions of chelating agents in concentrations 0.5-20 wt. % at elevated temperature, wherein the weight-percent ratio of the detonation nanodiamond material to an undiluted chelating agent is substantially 1 to 0.2. Impact treatment of the detonation nanodiamond material in chelating agent solution may include boiling, ultrasonication, cavitational disintegration, and harsh treatment in sealed chamber at temperatures of up to about 300° C. and high pressure. The method provides at least 5-fold reduction of metal-containing impurities in the resulting product, wherein the content of such elements as chromium and iron is reduced to negligible amounts.

The ozone cleaning device contains an electrically conductive member and a reinforced casing member. The casing member is injection-molded and houses the conductive member inside in an airtight manner. The reinforcement of the casing member, and the tight integration between the casing member and the conductive member jointly achieve enhanced structural strength to prevent the ozone cleaning device from being broken. When the ozone cleaning device is held close to a user and an electrical power is delivered to the conductive member, the conductive member is then conducting to the user and the air in between is influenced by the electrical power to produce ozone for cleaning. The present invention therefore achieves enhanced structural strength, usage safety, and prolonged operational life.
