The present application belongs to the field of inorganic metal hydrogen storage material preparation and processing technology, and particularly relates to an activation method of deactivated Ti-Mn-based AB2 type hydrogen storage alloy. The present application co-dopes a small amount of LaNi5 alloy and metal V in the long-stored and deactivated Ti-Mn-based AB2 type hydrogen storage alloy, grinds and mixes, manually press-molds, smelts, and then crushes to obtain a new type of high-performance Ti-Mn-based AB2 type composite hydrogen storage alloy, which can efficiently activate the existing deactivated Ti-Mn-based AB2 type hydrogen storage alloy, restore good initial kinetics and hydrogen storage capacity, and activate a large amount of long-stored and deactivated Ti-Mn-based AB2 type alloy without significantly affecting the cost of the alloy, thereby promoting the wide use of Ti-Mn-based AB2 type alloy in solid-state hydrogen storage devices.

This invention discloses a method for preparing a microcapsule-structured specialty coffee extract, the extract itself, and its applications, belonging to the field of fragrance and flavor technology. The method includes: adding an emulsifier to the specialty coffee extract and emulsifying it at 1530°C to obtain an emulsion; preheating a melamine resin prepolymer to 4045°C and adding it to the emulsion; raising the temperature to 4550°C within 15 minutes and adjusting the pH to 4.5-5.5 for the first stage reaction; then raising the temperature to 6080°C for the second stage reaction; and finally cooling and adjusting the pH to 7.5-8.5 to terminate the reaction, thus obtaining the microcapsule-structured specialty coffee extract. This invention, through room-temperature emulsification and a two-stage temperature-controlled process, effectively preserves the complex aroma of the specialty coffee extract. The resulting microcapsule structure is dense and stable, possessing both sustained-release and rapid aroma release via friction, significantly extending the aroma retention time. This invention also provides the application of the microcapsule-structured specialty coffee extract in the preparation of pet products.

The invention relates to the technical field of distilled liquor brewing and post-processing, and discloses a method for accelerating white liquor ester increasing through temperature-controlled plasma excitation, which comprises the following steps: S1, pretreatment: putting raw liquor into a processing container, introducing carbon dioxide gas into the raw liquor, and carrying out micro-nano bubbling treatment, dispersing and dissolving carbon dioxide in the wine body in the form of micro-nano bubbles to obtain pretreated white wine liquid; s2, plasma alcoholization: putting the pretreated white spirit liquid into a plasma reactor, starting a circulating pump to enable the white spirit liquid to circularly flow, and controlling the temperature of the white spirit liquid to be within a preset range; and S3, excitation treatment: starting a nanosecond pulse square wave power supply. A nanosecond pulse square wave power supply is matched with a carbon dioxide micro-nano bubble pretreatment technology, and transient self-induced electromotive force is induced on a gas-liquid interface by utilizing high-change-rate current generated by a nanosecond rising edge. And a high-specific-surface-area and subacid conductive environment is constructed in combination with micro-nano bubbles.
