The application discloses a kind of foamed metal foil for grain boundary diffusion, neodymium iron boron diffusion magnet and preparation method.The preparation method of the foamed metal foil for grain boundary diffusion of the application comprises the following steps:1) depositing a rare earth alloy film on the surface of a foamed metal foil sheet to obtain a coated foamed metal foil sheet;2) fold the coated foamed metal foil sheet obtained in step 1) in half, with the coated side facing in, and compress after folding to obtain a foamed metal foil for grain boundary diffusion.The foamed metal foil for grain boundary diffusion of the application enhances the adhesion of the rare earth alloy film, and when used for grain boundary diffusion, it increases the coercivity of the neodymium iron boron magnet while reducing the drop in remanence.

The application discloses a preparation method of whole wheat flour with controlled lipase and lipoxygenase activity, and relates to the technical field of whole wheat flour processing and storage. The method comprises the following steps: adopting DBD plasma to treat the bran of wheat grains, and then directly grinding the wheat grains to obtain the whole wheat flour. The method controls the lipase and lipoxygenase in the bran of the wheat grains, thereby stabilizing the whole wheat flour, prolonging the storage period of the whole wheat flour, and improving the nutritional quality and processing quality of the whole wheat flour. The DBD plasma treatment is performed at a power of 300-500 W for 60-180 s.

The present application relates to the technical field of water heaters, and discloses a control method of a gas water heater and the gas water heater. The gas water heater comprises a main heat exchanger, a condensing heat exchanger, a water inlet main pipe and an atomizer. The condensing heat exchanger has a water collecting cavity for collecting condensed water. The atomizer is used for atomizing the condensed water. The water inlet main pipe, the condensing heat exchanger and the main heat exchanger are sequentially communicated to form a water inlet waterway. When the real-time liquid level of the condensed water is greater than a preset liquid level threshold, the output load of the burner in the main heat exchanger is reduced. In this way, the gas water heater can reduce the generation amount of the condensed water when the condensing heat exchanger keeps working, reduce the situation that the condensed water liquid level reaches a dangerous liquid level, reduce the risk that the condensed water liquid level reaches the dangerous liquid level and triggers the shutdown of the gas water heater. Compared with stopping the work of the condensing heat exchanger to prevent the condensed water liquid level from rising, the condensing heat exchanger does not need to stop working and can continuously recover the heat in the high-temperature flue gas, so that the decline range of the thermal efficiency of the gas water heater can be reduced.

The invention discloses a hydrophobic anti-sintering indium oxide catalyst as well as a preparation method and application thereof, and belongs to the technical field of carbon dioxide hydrogenation catalysts. The hydrophobic anti-sintering indium oxide catalyst provided by the invention comprises an indium oxide catalyst carrier and a silane layer bonded on the surface of the indium oxide catalyst carrier, wherein the silane layer is formed by reacting a silane compound with hydroxyl on the surface of the indium oxide catalyst; based on the total mass of the hydrophobic anti-sintering indium oxide catalyst, the mass fraction of a silicon element in silane is 0.5-0.9 wt%. The silane is chemically bonded on the surface of the indium oxide carrier, so that sintering and grain growth of indium oxide nanoparticles under a high-temperature reaction condition are remarkably inhibited on the premise of not changing an active crystal phase of the indium oxide carrier, and the adaptability of the catalyst under a harsh working condition of a water-containing product is remarkably improved.

The invention discloses a trabectedin-loaded nano-micelle and oxaliplatin-loaded drug combination composition and application, and relates to the technical field of delivery and drug combination, and the trabectedin-loaded nano-micelle and oxaliplatin-loaded drug combination composition comprises trabectedin-loaded nano-micelle and oxaliplatin. The invention also discloses an application of the combined pharmaceutical composition in preparation of antitumor drugs. According to the invention, a pH-sensitive amphiphilic biodegradable material (such as PCL-PEOz) and a chemical drug are self-assembled to form stable micelles, so that the bioavailability of the drug is improved, the critical concentration of the micelles is reduced, and long-acting circulation in vivo is realized; the system can be combined with oxaliplatin for use, so that the sensitivity of tumor cells to oxaliplatin is promoted, the synergistic effect of chemotherapy and immunotherapy is exerted, the treatment effect of malignant tumors is improved, and the tumor microenvironment is improved.
