Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.
The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.
In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.

Overview of vanadium nitride VN powder
Vanadium nitride is formed during the nitriding process of steel and increases wear resistance. During the nitridation process, another phase V2N (also known as vanadium nitride) can be formed together with VN. VN has a cubic rock salt structure. There is also a low-temperature form, which contains the V4 cluster. The low temperature phase is caused by dynamic instability when the vibrational mode energy in the high temperature NaCl structural phase drops below zero.
Vanadium nitride is a strongly coupled superconductor. Nanocrystalline vanadium nitride is said to have potential for use in supercapacitors. The properties of vanadium nitride are sensitively dependent on the stoichiometry of the material.
How is vanadium nitride VN powder produced?
The samples made of ammonium metavanadate powder and carbon powder were pre-reduced in a heating furnace, followed by final reduction. After the final reduction is completed, the sample is cooled with the furnace, and the obtained sample is vanadium nitride; in the process, the temperature in the heating furnace is 650-670° C., and the holding time of the heating furnace is 2-4 hours. Under the conditions of this temperature and holding time, the surface of the sample can be prevented from melting and hindering the reduction reaction.
After pre-reduction, the main reduction product of the sample is V2O3, and the rest are carbides and a small amount of VN; in the final reduction process, the sample is kept at 1300-1500 °C. CO gas and CO gas are generated during the insulation process. The introduced nitrogen gas is taken away, and VN is obtained after the insulation is completed; the nitrogen flow rate during the reaction is 210-270 mL/min, which can not only meet the kinetic conditions of the reduction reaction, but also prevent the reaction temperature caused by too much nitrogen. reduce and waste nitrogen;
Application of vanadium nitride VN powder
Vanadium nitride has high wear resistance, which can greatly improve vanadium steel after nitriding.
The comprehensive mechanical properties of high-strength steel, such as strength, toughness, ductility, and thermal fatigue resistance, endow the steel with good weldability. In the case of achieving the same strength, adding vanadium nitride can save 20-40% of the vanadium addition, thereby reducing the cost.
Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron. Vanadium Nitride Alloys for High Strength Low Alloy Steels
Vanadium nitride can carry out effective vanadium-nitrogen microalloying at the same time, promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and play a more effective role in strengthening sedimentation and refinement.
Adding vanadium nitride to steel can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, so that the steel has good weldability.
In the case of achieving the same strength, adding vanadium nitride can save 30-40% of the vanadium addition, thereby reducing the cost. Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron.
The vanadium-nitrogen alloy used for high-strength low-alloy steel can simultaneously carry out effective vanadium-nitrogen microalloying, promote the precipitation of carbon, vanadium and nitrogen compounds in the steel, and play a more effective role in sedimentation strengthening and graining. refinement.

The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry. In 2020, global revenue from the travel and tourism industry was estimated to drop from a forecasted 711.94 billion U.S. dollars to 568.6 billion U.S. dollars, representing a decrease of over 20 percent. The region predicted to see the highest decline in revenue was Europe, decreasing from 211.97 billion U.S. dollars in 2019 to roughly 124 billion U.S. dollars in 2020.
