Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.

Nano silica fume overview
Nano silicon powder is a new generation of wide bandgap energy semiconductor optoelectronic semiconductor material, and it is also a high-power light source material.Silicon nanoparticles (SiNPs) are biocompatible, metal-free quantum dots with size- and surface-customizable photoluminescence. Silicon nanoparticles consist of pure amorphous nano-silica. The particle size is less than 5 nanometers, and the particle size range is narrow.
Silicon nanoparticles are known to be absorbent and abrasive, and mesoporous silicon nanoparticles have important applications in drug delivery and nanomedicine. In the past decades, silicon nanoparticles have attracted great attention due to their interesting physical properties, active surface states, unique photoluminescence, and biocompatibility.
Physical and chemical properties of nano-silica powder
Nano silicon powder has the characteristics of high purity, small particle size, uniform distribution, large specific surface area, high surface activity and low bulk density. It is non-toxic, odorless and has good activity. Nano-silicon powder is a new generation of optoelectronic semiconductor materials, with a wider band gap energy semiconductor, and is also a high-power light source material.
The preparation methods of nano-silicon powder include mechanical ball milling, chemical vapor deposition, and plasma evaporation and condensation. The industrial production of nano-silica fume in western countries started early, and there are specialized silicon powder product companies, such as Japan Chemicalbook, American DuPont, Germany HCStark, Canada Tekner and so on. Using the condensation method to produce a variety of high-purity nano-silica powders with different particle sizes, it is in a leading position in the world in production technology.
Application of nano silicon powder
1. Nano-silicon wires that can be used to make nano-silicon-carbon anode materials for rechargeable lithium batteries, or coating graphite on the surface of nano-spherical silicon powders as silicon-carbon anode materials for rechargeable lithium batteries. It can increase the capacity and the number of charge-discharge cycles of rechargeable lithium batteries by more than 3 times;
2. Can be used for high temperature resistant coatings and refractory materials. It can react with organic matter as the raw material of organic silicon polymer material;
3. It can be applied to coating to form nano-silicon particle film, which is widely used in solar energy;
4. Nano-spherical silicon powder and diamond are mixed under high pressure to form nano-silicon carbide-diamond composite material, which can be used as a tool to provide strength and toughness;
5. As a nano-silicon carbon anode material for lithium-ion batteries, nano-silicon powder has a high theoretical specific capacity (theoretical value of 4200mAh/g), which is much higher than that of carbon materials;
6. More than ten kinds of silicon nanoparticles/silicon oxide nanostructures have been designed on silicon nanoparticle substrates, realizing photoluminescence in the main band from near-ultraviolet to near-infrared and low-threshold electroluminescence under forward or reverse bias. Luminescence, photoluminescence and electroluminescence models were proposed, which laid the foundation for the realization of silicon-based optoelectronic integration.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
