The secretary general of the Organization of Petroleum Exporting Countries (OPEC) said recently that US economic sanctions against Venezuela have affected global energy supplies. 

He told Venezuelan media that the ECONOMIC sanctions imposed by the United States on Venezuela and other countries have seriously affected the ability to produce and export oil worldwide and violated the right of people in other countries to use energy.

Venezuela has one of the largest proven crude oil reserves in the world, but U.S. sanctions have made it impossible for Venezuela’s oil industry to consistently export reliable energy to the world, he said. Despite this, he highly appreciated the efforts of the Venezuelan oil industry to maintain Nano silicon powder ,Nano silica fume overview,Application of nano silicon powder,Nano silica powder price,Nano silica powder supplier are expected to increase in the future.

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.

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.
