A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including Manganese oxide Mn2O3.
Overview of manganese oxide Mn2O3
Manganese oxide Mn2O3 is an oxide with chemical formula of Mn2O3 and molecular weight of 157.88. It is a black cubic crystal. The relative density is 4.50. Mn2O3 is different from many other transition metal oxides because it does not adopt corundum (Al2O3) structure. II. Generally recognized form of Mn2O3, i.e α- Mn2O3 and γ- Mn2O3.Mn2O3 is insoluble in water, acetic acid and ammonium chloride solution, but soluble in other inorganic acids. Dissolve in cold hydrochloric acid to form Brown solution, form red solution in hot dilute sulfuric acid or concentrated sulfuric acid, decompose into MnO2 and manganese nitrate, and decompose into Mn3O4 and release O2 in hot nitric acid. Manganese trioxide can be used in the printing and dyeing process of fabrics, the oxidation process of carbon monoxide and organic compounds, the synthesis of soft magnetic materials, or the synthesis of lithium-ion batteries as an important basic material.
When MnO2 is heated below 800 ℃ in air, it will form α- Mn2O3 (higher temperature will produce Mn3O4). γ- Mn2O3 can be prepared by oxidation of manganese hydroxide (II) and then dehydration. The preparation of many nanocrystalline Mn2O3 has been reported, such as the oxidation of mnii salt or the synthesis of MnO2 reduction.
Manganese oxide (III) is formed by redox reaction in alkaline battery:
2MnO2 + Zn→Mn2O3 + ZnO
Manganese oxide (III) should not be confused with mnooh manganese hydroxide (III). Compared with Mn2O3, mnooh is a compound that decomposes to form MnO2 at about 300 °C.
Application of manganese oxide Mn2O3
Manganese oxide Mn2O3 is a highly insoluble and thermally stable manganese source, which is suitable for glass, optical and ceramic applications. Manganese oxide is a black / brown solid, high-purity (99.999%) manganese oxide (MnO) powder, which is the main natural source of manganese.
Manganese oxide minerals have a history of thousands of years - the ancients used them to make pigments and transparent glass, and now they are used as manganese, catalysts and battery materials. Manganese is distributed in various geological environments.
1. Mn2O3 has a wide range of uses and can be used in the printing and dyeing process of fabrics.
2. Mn2O3 can effectively catalyze the oxidation of organic pollutants and nitrogen oxides, and catalyze the organic coupling reaction.
3. Mn2O3 can be used as a precursor of soft magnetic materials.
Mn2O3 can be used as the raw material of lithium ion battery.
5. Mn2O3 is the raw material and intermediate product of manganese compounds.

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.
