Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk copper oxide are still very uncertain.
What is Cu2O?
Cu2O or cuprous oxide is an oxide of univalent copper, usually in the form of brick red or reddish-brown crystals and powders. Cu2O is rich in nature, mainly in the form of chalcopyrite.
Cu2O is insoluble in water and organic solvents, but soluble in dilute hydrochloric acid, dilute sulfuric acid and ammonium chloride solution. Cuprous oxide is relatively stable at room temperature and dry conditions, and can be oxidized to CuO only after heating for a long time or in moist air.
What is Cu2O used for?
Cuprous oxide is used to make a ship bottom antifouling paint (killing low-grade marine animals). Used as fungicides, colorants for ceramics and enamels, red glass stains, and materials for making various copper salts, analytical reagents and rectifier electroplating in the electrical industry, fungicides for crops and rectifiers, etc. Cuprous oxide is also often used as a catalyst for the synthesis of organic compounds.
In recent years, Cu2O has attracted more and more attention, because Cu2O is a p-type semiconductor material with excellent properties, and has the advantages of non-toxic, easy to prepare, good chemical stability, etc. It has special optical and magnetic properties and has potential applications in the fields of photocatalysis and photoelectric conversion. The band gap is about 2.17 ev, which can absorb visible light for photocatalysis and photoelectric conversion in theory, and the highest photoelectric conversion efficiency can reach 18%.
Because of the excellent performance and promising application potential of Cu2O, researchers are committed to the preparation of Cu2O with various morphologies and structures, such as conventional films, porous films, micro-nanostructure films, nanowires and nanowires and so on.
What is CuO?
CuO or cupric oxide is a black oxide of divalent copper. Slightly bisexual and slightly hygroscopic. Copper oxide is insoluble in water and ethanol, easily soluble in acid, stable to heat, and decomposed into oxygen at high temperature.
What is CuO used for?
Copper oxide can be used as organic synthesis catalyst, analytical reagent (for nitrogen determination), oxidant, catalyst and petroleum desulfurizer, and can also be used for the determination of carbon in organic compounds.
Used as a colorant for glass, enamel and ceramic industry, anti-wrinkle agent for paint and polishing agent for optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in rayon manufacturing industry and as a desulphurizer for grease. It is used as the raw material for the manufacture of other copper salts and for the manufacture of artificial gems.
Difference Between Cu2O and CuO
Cuprous oxide Cu2O and copper oxide CuO are compounds of the chemical element copper. These oxides contain copper in different oxidized states. In addition, there is a +1 oxidation state in cuprous oxide and a +2 oxidation state in copper oxide.
The main difference between cuprous oxide and copper oxide is that cuprous oxide is crimson while copper oxide is black.
Another difference between cuprous oxide and copper oxide is that cuprous oxide naturally exists in the form of reddish minerals, chalcopyrite, while copper oxide exists in the form of mineral pyrite.
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

On August 1, the European Union officially began to implement the "voluntary reduction" agreement on natural gas adopted last month. Under the agreement, EU member states will reduce gas demand by 15 per cent from the average consumption over the past five years through measures of their choice between August 1 this year and March 31 next year.
Several major German cities, such as Berlin, Hanover and Munich, have begun to take measures to reduce energy consumption. Berlin, for example, decided to turn off the lights of more than 200 tourist attractions at night. Berlin's municipal buildings will have indoor temperatures of no more than 20 degrees Celsius between October 1 and March 31 next year, and only nurseries, schools, nursing homes and hospitals can be exempted from energy-saving measures.
Spain's energy conservation plan forces companies, businesses and vehicles to limit air-conditioning temperatures in summer and heating temperatures in winter. The above-mentioned places must limit the air-conditioning temperature to more than 27 degrees Celsius in summer and the heating temperature below 19 degrees Celsius in winter. The plan requires that shop window lighting be turned off at 22:00. The plan also requires the administration to regularly review the heating systems of enterprises in order to avoid energy waste.

As many researchers believe, graphene floating on the water does not repel water, but attracts it. Graphene is made of the same material as graphite-for example, found in pencils-which is why graphene has long been thought to be as waterproof as gra…
