Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.

According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.

Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.

The supply and prices of many other MnO2 powder are expected to continue to be influenced by international situations.

What is Manganese Dioxide MnO2?
Manganese dioxide is an inorganic compound with the molecular formula MnO2. This black or brown solid is the natural mineral pyrolusite, the main ore of manganese and a constituent of manganese nodules. 
The main use of MnO2 is in dry batteries such as alkaline batteries and zinc-carbon batteries. Manganese dioxide is also used as a pigment and a precursor of other manganese compounds, such as potassium permanganate. It is used as a reagent in organic synthesis, for example, for the oxidation of allyl alcohol. 
 
What is Manganese Dioxide MnO2 Used For? 
Used as a dry cell depolarizer. 
Used as catalysts and oxidants for the synthetic industry. 
Used as colorants, bleaching agents, and iron removal agents for the glass industry and enamel industry.
Used for manufacturing manganese metal, special alloy, ferromanganese castings, gas masks, and electronic materials such as ferrite. 
Used in the rubber industry to increase the viscosity of rubber. 
 
Organic synthetic use:
Manganese dioxide is very useful in organic chemistry. Manganese dioxide is used as an oxide in different forms, because manganese dioxide has multiple crystalline forms, the chemical formula can be written as MnO2·x(H2O) N, where x is between 0 and 0.5, and n can be greater than 0.  Manganese dioxide can be formed from the reactions of potassium permanganate (KMnO4) and Manganese sulphate (MnSO4) at different pH values. 
One chemical reaction specific to manganese dioxide is the conversion of alcohols to aldehydes. Even if the alcohol has a double bond, it will not be oxidized by manganese dioxide: cis-RCH=CHCH2OH + MnO2 → cis-RCH=CHCHO + H2O + MnO 
No matter how active the product is, it doesn't get oxidized again. Diols can be oxidized to dialdehyde by manganese dioxide. Other reactions of manganese dioxide are very many, and can be used in the oxidation of amines, aromatic substances and triols.
 
Laboratory use:
Used as a catalyst for the decomposition of hydrogen peroxide to produce oxygen; Used as a catalyst for the decomposition of potassium chlorate to produce oxygen; Manganese was prepared by aluminothermic reaction with elemental aluminum powder. Used as pigment, yellow glass, etc. Reaction with hot concentrated hydrochloric acid to produce chlorine gas; Reaction with molten potash (potassium hydroxide) in the air to prepare potassium manganate; In the decomposition reaction of potassium permanganate, manganese dioxide acts as self-catalyst of potassium permanganate. 
 
Is MnO2 Explosive? 
It reacts violently with combustible and reductive substances. This creates fire and explosion hazards. 
 
Is Manganese Dioxide Harmful? 
Strong oxidant. Contact with other materials may cause a fire. Harmful by inhalation or swallowing. May cause eye, skin, and respiratory irritation. May cause central nervous system effects. Inhalation of smoke may cause metal smoke fever. According to animal studies, it may cause adverse reproductive effects.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".

The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.  

The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.

The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.

Affected by several factors, the supply of the MnO2 powder is erratic and thus its prices are expected to go higher in the future.
