What is SiO2 nanoparticles used for?

According to the monthly report of the International Energy Agency (IEA), the gap between European crude oil imports from Russia and the United States has narrowed sharply in the past few months, and the United States is in a position to replace Russia as Europe's largest supplier after Russia's oil ban takes effect in December.

Malaysia will export more palm oil to EU member states, as at least three EU countries that have never imported Malaysian palm oil have started to import it in recent months, Malaysia's planting and Commodity Minister said recently. She said that data released by the Malaysian Ministry of planting and Commodities showed that from January to July, Estonia imported 2501 tons of Malaysian palm oil worth 20.22 million MYR, while the Czech Republic imported 95 tons of Malaysian palm oil worth 880000 MYR. In the same period, Hungary imported 8.53 million tons of Malay palm oil, valued at 6.73 million MYR. She also said that the country had also strengthened its relations with existing major palm oil export destination countries, particularly India, China, Pakistan and the European Union. It will greatly promote the development of new markets for palm oil nano silica are still very uncertain.

Ceramic field.
The disadvantages of modern oxide ceramic products are brittleness and low finish. The addition of silica nanoparticles to ceramics can greatly reduce the brittleness of ceramic products and improve the toughness of ceramic products.
 
Rubber field.
Traditional rubber products are made by adding carbon black to improve strength, wear resistance and aging resistance, and the color is single. Rubber products with novel color and excellent properties can be prepared by adding silica nanoparticles to rubber and making use of its excellent optical properties.
 
Paint field.
Because silica nanoparticles are resistant to ultraviolet radiation, adding them to the coating can improve its stability, weather resistance and thixotropy. In addition, it can also improve the adhesion between the film and the wall.
 
Textile field.
Silica nanoparticles have a wide application prospect in the textile field, mainly because of their anti-aging, anti-ultraviolet, anti-bacterial and deodorizing functions. The addition in the preparation of functional fiber can improve the anti-ultraviolet radiation ability of the product and have the effect of purifying air.
 
Cosmetic field.
Silica nanoparticles have strong chemical stability and are not easy to decompose under ultraviolet light, which meets the requirements of cosmetics and sunscreen products to shield sunlight ultraviolet rays, and the color of the particles is white, so adding it to cosmetics can not only achieve sunscreen effect, but also achieve whitening effect.
 
Catalytic field.
Catalysts play an important role in chemical industry, especially heterogeneous catalysts with high reaction activity and reusability. The activity and selectivity of the catalyst determine the reaction rate of the chemical reaction and the yield of the reaction products, so in order to obtain a highly active catalyst, it is necessary to adjust the surface properties and structure of the catalyst carrier. Silica nanoparticles are not only chemically stable, but also have small particle size and large specific surface area. As a carrier, the catalyst can reach nanometer scale without agglomeration. Therefore, catalysts with low cost, high catalytic activity and long service life can be prepared.
 
Environmental protection.
Because of its small particle size, silica nanoparticles have large specific surface area, and special functional groups can absorb a variety of harmful substances after surface modification, so they are widely used in the field of environmental protection.
 
Biomedical field.
Silica nanoparticles not only have high stability, but also have biocompatibility and low toxicity, so they have good application prospects in the field of biomedicine, such as drug controlled release, gene carrier, biosensor and so on. The addition of silica nanoparticles to pharmaceutical preparations has been widely used, because the addition of silica is not only non-toxic and harmless, but also has the characteristics of high absorption, good dispersion and proper thickening. The fluidity of ranitidine, meglumide and valencil can be changed by adding a small amount of silica nanoparticles to the drugs.
 
Others
A large number of unsaturated bonds and hydroxyl groups exist on the surface of nano-silica, and such a strong chemical adsorption film can be formed on the friction sub-surface. therefore, it can be used as a high-performance, high-environment-friendly lubricating oil additive to protect the friction surface of metal and improve the friction performance of lubricating oil.
 
The application of nano-silica in color inkjet printing can improve the printing quality, reduce the ink dot area, increase the color density and enhance the image fidelity, because of its excellent ink fixation performance and specific micropore network.
 
Nano-silica is an inorganic rigid particle, so it has the characteristics of toughening plastics. gas-phase nano-silica can improve the toughness or even rigidity of the material without weakening the rigidity of the material.
 
It is possible to prepare porous thermal insulation materials with high mechanical strength, energy saving, environmental protection and good hydrophobicity by using the thermal insulation properties of nano-silica, which is of great significance in military, industrial and other fields.
 
In the field of agriculture, nano-silica can be used as a seed treatment agent to shorten the growth cycle of corn, cotton, wheat and so on. In alcohol production, the addition of appropriate nano-silica can purify and prolong the shelf life, and can also be used as the carrier of efficient pesticides, anti-caking agent in feed and so on.
 
In the paper industry, it can effectively improve the whiteness, strength, wear resistance and opacity of the paper; high-grade nano-silica can also be used as a friction agent and drug shaping dispersant for toothpaste; as a matting agent, nano-silica can also partially replace expensive titanium dioxide in paints, inks, cosmetics, coatings and other fields.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.  

The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.  

Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.  

U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.  

The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."  

The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled nano silica are estimated to be influenced by international political situation changes.
