Disclosed are an additive raw material composition and an additive for superhard material product, a method for preparing the additive, a composite binding agent, a superhard material product, a self-sharpening diamond grinding wheel and a method for manufacturing the same. The raw material composition consisting of components in following mass percentage: Bi2O3 25%40%, B2O3 25%40%, ZnO 5%25%, SiO2 2%10%, Al2O3 2%10%, Na2CO3 1%5%, Li2CO3 1%5%, MgCO3 0%5%, and CaF2 1%5%. The composite binding agent is prepared from the additive and a metal composite binding agent. The self-sharpening diamond grinding wheel prepared from the composite binding agent has high self-sharpness, high strength, and fine texture, is uniformly consumed during the grinding process, does not need to be trimmed during the process of being used, and maintains good grinding force all the time, fundamentally solving the problems of long trimming time and high trimming cost of the diamond grinding wheel.

The present invention relates to a method for producing lithium hydroxide and lithium carbonate, wherein the lithium hydroxide and the lithium carbonate can be produced by a series of steps of: performing bipolar electrodialysis of a lithium-containing solution from which divalent ion impurities have been removed; concentrating lithium in the lithium-containing solution and at the same time, converting the lithium to lithium hydroxide; and carbonating the lithium hydroxide to obtain lithium carbonate.

Silver sulfadiazine-immobilized inorganic fillers are described, and their synthesis is presented. The fillers are believed to have utility in dental composites and dental adhesives to achieve potent, long-term, and none-leaching antimicrobial effects.

Waste water is treated by contacting it with sodium to form hydrogen which is then contacted with air in a combustion chamber to produce clean water and heat.

A method for optimizing reduction and content of total titratable alkali of green liquor of a recovery boiler. The method comprises producing green liquor in a dissolving tank by conveying smelt and weak white liquor into the dissolving tank and measuring at least the contents of sodium sulphate, sodium hydroxide, sodium sulphide, and sodium carbonate of the green liquor. The method comprises controlling at least a process parameter of a recovery boiler to maximize the reduction of the recovery boiler and controlling the flow of the weak white liquor into the dissolving tank to optimize the content of total titratable alkali of the green liquor. In addition, a system for producing green liquor with optimized reduction and content of total titratable alkali. The system comprises a first sensor arrangement, a first and a second regulator, and a processing unit arrangement configured to perform the method.

An aqueous organ preservation solution includes taurine and L-alanine-L-glutamine and glutamic acid. The organ preservation composition can be stored in a solid state, for example in the form of small particles (e.g. a powder or micronized powder), and be dissolved in water, thereby instantly providing a ready-to-use organ preservation solution.
