Recently, batches of new energy products have left the workshop and been exported overseas in the northern industrial park of Dalong Economic Development Zone, Guizhou; The construction sites of major projects are lined with towering cranes and roaring machines Watching the cars coming and going in the 250000 ton lithium-ion battery cathode material industrial park, Wang Xiusheng, the general manager of Guizhou Jiashang New Energy Technology Co., Ltd., is full of confidence. He said that currently, the first production line of Phase One is operating at full capacity, the second and third production lines are undergoing trial production, and the fourth production line is waiting to be started; The second phase project is accelerating its progress. It is reported that the industrial park is invested and controlled by Guangdong Jiashang New Energy Technology Co., Ltd., and constructed and operated by Guizhou Jiashang New Energy Materials Co., Ltd. The main construction includes two phases: a production line with an annual output of 100000 tons of lithium manganese oxide cathode materials, 40000 tons of ternary cathode materials, 10000 tons of lithium cobalt oxide cathode materials, and 100000 tons of lithium iron phosphate cathode materials, as well as related supporting facilities. Guizhou Jiashang is one of the largest production bases in the field of mobile power battery cells in China. Its products have the characteristics of high safety, long service life, good energy density, and stable performance. Thanks to the circular industry chain of the park, 60% to 70% of their production capacity is used for internal needs of the headquarters, and the remaining 30% to 40% is invested in nearby park enterprises such as Zhongwei Corporation. This not only achieves a win-win situation for enterprises, but also facilitates the industrial cycle of the industrial park. In recent years, Tongren City has leveraged the advantages of local manganese resources to focus on three major industries: high-end battery manufacturing, energy storage battery material production, and waste battery recycling. This has formed a "dual chain" driving pattern of the new energy battery material industry chain and the manganese based functional material industry chain for deep processing of manganese, continuously promoting the cluster development of the new functional material industry. At the same time, through vertical integration layout, a circular chain is created from aspects such as production costs, raw material supply, and product sales, promoting the formation of a symbiotic relationship between multiple industries and various types of institutions in the industrial park, and allowing the new functional materials industry to revive. The products we produce can be sold on-site to enterprises in the park, forming an upstream and downstream industrial chain, not only achieving short distance transportation, but also reducing transportation costs, "said Tan Xiaojun, Chairman of Guizhou Nengkuang Manganese Industry Group Co., Ltd. Close cooperation between enterprises is the foundation for forming industrial clusters and the key to winning the market. In the new material recycling workshop of Zhongwei Corporation not far away, high-purity manganese sulfate transported from Nengmin Manganese Industry through pipelines is processed together with cobalt sulfate and nickel sulfate to form ternary precursor materials for lithium batteries that promote the company's development. Without leaving the industrial park, the raw materials and semi-finished products produced by upstream enterprises can be sold to downstream companies in the industrial park. Huicheng New Materials sells high-purity manganese sulfate to Zhongwei New Materials for processing into nickel cobalt manganese hydroxide, Red Star Development Dalong Manganese Industry supplies electrolytic manganese dioxide to Bestech to generate lithium manganese oxide, and Dansdi assembles ternary positive electrode materials from Zhongwei New Materials into ternary lithium batteries The industrial development pattern of creating a circular chain in the industrial chain, Tongren's supplementary chain and extended chain industrial clusters is continuously strengthened, gathering a group of industry leaders and high-quality enterprises such as Zhongwei, Huicheng, Hongxing, Nengkuang Manganese Industry, Sanhe Manganese Industry, Wuling Manganese Industry, etc. Data shows that in the first half of this year, there were 147 industrial enterprises above designated scale in Tongren City that were associated with the "Rich Mining and Precision Development" initiative, with a total output value of 12.596 billion yuan, a year-on-year increase of 4.28%. At present, Tongren has formed a lithium-ion power battery material recycling industry chain that integrates positive electrode materials, negative electrode materials, and comprehensive recycling research and development. It is a new functional material industry cluster centered on high-purity manganese sulfate, nickel cobalt manganese ternary precursors, lithium manganese oxide, and graphite for lithium-ion power battery negative electrodes. sulfate-free,sulfuric acid,sulphate,sulfuric acid

　Chinese scientists have revealed the mechanism of human phosphate efflux protein operation. Recently, the Chinese Academy of Sciences Institute of Physics researcher Jiang Daohua team's research results paper published in the international academic journal “Nature” magazine, the research team using cryo-electron microscopy single-particle technology and phosphate efflux functional system, the phosphate efflux protein XPR1 structure and function of the analysis, elucidated the XPR1 phosphate transport and regulatory mechanisms. 　　Phosphorus is the sixth most abundant macronutrient in the human body, and each adult contains about 1 kilogram of phosphorus. The Han Dynasty writer Wang Yi wrote in “Nine Thoughts - Lamenting the Years” that “God's light blazes, and ghostly flames flicker”, in which the “ghostly flames” are caused by the spontaneous combustion of phosphine produced during the degradation of corpses. 1669, the German chemist Hennig Brand was searching for the “Philosopher's Stone”, which is the most important element in the human body. In 1669, the German chemist Hennig Brand in the search for the “Philosopher's Stone” in the process, from 50 barrels of human urine accidentally obtained a kind of ash like material, can emit blue-green flame. 　　And modern research has shown that phosphorus is involved in almost all physiological processes in living organisms: phosphate is a major component of bones and teeth; phosphorus is involved in acid-base balance; and proteins regulate cellular metabolism by using phosphorylation/dephosphorylation as a signal. 　　More importantly, the human body has a system that regulates phosphate homeostasis and maintains the body's phosphate balance by controlling phosphate uptake and efflux. Among them, XPR1 is the only known phosphate efflux protein in mammals. 　　This time, what Daohua Jiang's team revealed is the mechanism of phosphate excretion by XPR1.     According to Daohua Jiang, adults obtain about 1,000 milligrams of phosphate from food every day, of which about 700 milligrams are absorbed by the body in the digestive and urinary systems, and the remaining phosphate is excreted in the urine and feces. Of the absorbed phosphate, 85% is stored in the body's bones and teeth, 14% enters the intracellular fluid, which maintains intracellular phosphate homeostasis, and about 1% enters the serum, which maintains phosphate homeostasis among the body's tissues. Despite this importance of phosphate in the human body, the accumulation of excess phosphate can lead to many adverse consequences, including tumorigenesis, depression, and neuronal disorders. Therefore, it is especially important to get excess phosphate out of the cell. However, how does protein XPR1 save the day on the cellular level and save phosphorus-imbalanced cells from “fire”? This has long been an unsolved mystery. XPR1 first appeared in the field of vision of scientists as a cell surface receptor for retroviruses. People have since discovered that this small protein is actually multi-tasking. 　Jiang Daohua told reporters that XPR1 contains a transmembrane structural domain, but also has a universal in animals, plants and microorganisms in the “versatile” protein SPX structural domain. This “match” protein as the inositol polyphosphate receptors, can feel the cell due to phosphate excess and issued “SOS”. From the exocytosis of phosphate, to sensing the “SOS” signal, and finally saving the cells from “phosphorus”, what exactly did XPR1 do? In order to find out the truth, the research team analyzed the high-resolution structures of XPR1 in three different conformations: closed, open, and bound to inositol-6 phosphate. Based on the structural and functional results, the researchers found that there are three sites in XPR1 formed by positively charged amino acids that bind phosphates by positive and negative attraction; when these phosphates are bound to XPR1, it induces a conformational change in XPR1, forming a channel through the cell membrane that allows phosphate ions to flow out of the cell. 　XPR1 protein is very “smart”, in order to avoid excessive phosphate ion efflux leading to nutrient loss, it will utilize a flexible loop at its end to control the size of the channel opening. The SPX domain regulates the flux of phosphate ions out of XPR1 by sensing the concentration of phosphatidylinositol in the cell. 　　The study reveals that XPR1 is structurally similar to transporter proteins but adopts a novel channel-like gating mechanism for exocytosis of phosphate, which is significantly different from the alternately open transporter mechanism employed by the vast majority of transporter proteins. 　　“These findings are crucial for the study of phosphate homeostasis in the human body.” Despite the stage-by-stage progress made, some key issues still need to be explored in further research, and the team will continue to tackle the problem in this area in the future, said Jiang Daohua. phosphates,NH4H2PO4,Inorganic compounds,Inorganic salt compounds,White crystalline powder

This reporter learned from Harbin Institute of Technology (Shenzhen) on September 8 that the group of Professor He Sisi and Associate Professor Zhou Jia of the School of Science of the university made a breakthrough in the field of nitrate electrocatalytic conversion, designing a highly efficient electrocatalyst that utilizes and efficiently converts nitrate into ammonia in wastewater, which provides a new way for wastewater treatment and low-carbon energy production. The related research results were recently published in Nature Communications. Electrocatalytic nitrate reduction to ammonia (hereinafter referred to as NRA) is considered to be a low-cost and sustainable way of obtaining ammonia energy, which is capable of converting nitrate from industrial wastewater into ammonia, a clean energy source. In this study, the researchers proposed a gradient concentration structure-driven design to accelerate the reaction of nitrate electroreduction for ammonia production from low nitrate concentration, and tested the gradient-structured NRA electrocatalysts with more than 93% Faraday efficiency for ammonia production and industrial-grade ammonia current density of 1.0 amperes per square centimeter at low nitrate concentration of a typical industrial wastewater (2,000 ppm), while operating stably for for up to 720 hours. Meanwhile, the researchers also combined in situ spectroscopic characterization and theoretical calculations to reveal the NRA reaction mechanism of the catalyst. The membrane electrode device assembled by this reaction mechanism can work stably at high current density for more than 100 hours, confirming that this NRA catalyst has industrial potential. It is reported that this research is of great significance to promote industrial wastewater treatment and electrocatalytic green ammonia preparation, and then realize the green low-carbon energy strategy. nitrate,nitrate salt,sulfate-free,HNO₃，Ionic compounds.
