Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.

Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the nano silica market.

What is Nano Silica?
Silicon Dioxide nanoparticles, also known as silica nanoparticles or nano-silica, appear in the form of white powder.
Nanometer silica particles can be divided into P-type and S-type according to their structure. P-type particles are characterized by a large number of nanopores, with a porosity of 0.61 mL /g, and higher UV reflectivity than S-type particles. The latter also has a relatively small surface area. 
Nano silica has the characteristics of light volume, fluffy, bulk density of less than 0.15-0.2g/cm3, a specific surface area of more than 500 m2/g, and high chemical activity. 
Because the surface contains an OH- bond, nano silica is a kind of acid oxide, belonging to the silicate acid group, has hydrophilic, and the water absorption rate is more than 5 times its own.   
The main application of silica nanoparticles is as additives in rubber and plastic manufacturing; As a reinforced filler for concrete and other building composites; As a stable, non-toxic platform for biomedical applications such as drug delivery and therapeutic diagnostics.
 
What is Silica?
Silicon, or silicon, is one of the chemical elements found in the earth's crust. Its oxide forms are silicate (SiO4) and silicon dioxide (silica, SiO2). 
Silicon is commonly used in industry, while its oxide form is commonly used in biomedical applications. SiNPs have several rare properties, such as ease of synthesis, surface modification, strong mechanical properties, and relatively inert chemical composition.  They have been used as biological materials for decades. 
Silica comes in two basic forms: crystalline and amorphous. The two forms have the same molecular formula, but their structural arrangements are different. Crystalline silica has a regular lattice arrangement, while amorphous silica has an irregular lattice arrangement.  Crystalline silica comes in many forms. A well-known form is alpha-quartz, which can be converted by heating to β -quartz, squamous quartz, and quartzite. There is also porous crystalline silica called a porosil. All porosils are synthetic products. 
Mesoporous silicon and silica particles are ideal candidates for controlled drug release because of their rare properties, such as high surface area, large pore volume, adjustable pore size, and good chemical and thermal stability. Amorphous silica can be divided into three categories: natural forms, byproducts of power stations and metallurgical processes, and synthetic forms. Amorphous silica is considered to be a very promising gene carrier and molecular imaging candidate, mainly because of its highly tunable biocompatibility and stability. It is also used in dietary supplements, catheters, implants, and dental fillers.
 
What is nano-silica used for? 
Nano silica is used to modify the dispersion and plasticity of cement concrete, thus giving it impermeability, enhanced impermeability, frost resistance, reducing hydration heat, and prolonging service life. 
Used as strengthening agent, vitrification agent, and adhesive of ceramics, enamels, and glazes. It is also a high thermal binder for engineering-grade ceramics and refractories. 
Nanocomposite material modifier, used as an inorganic adhesive at high temperature; As an additive for inorganic composite materials, used for strengthening, molding, and filling of rubber/polymer materials. In addition, can be used as a variety of resin engineering materials; High-quality FRP corrosion-resistant packing. 
Used as cement seal of oil well, underwater seal, and reinforcement material of under-ground engineering; It has the following characteristics: engineering shielding, anti-radiation, stealth, electricity, anti-bacteria; It is good for chemical absorption, catalysis, and enhancement.
Special use, such as lamp paint, lubricating oil, thickener, steel dehydrogenate, and inner wall paint sensitive materials. Energy storage filler for solar cells and power cells. 
 
Is nano-silica toxic? 
The health effects associated with silica exposure, particularly crystalline silica, have been extensively studied. 
Studies have shown that occupational exposure to crystalline silica induces silicosis, a fibrotic lung disease, in workers, and that exposure is associated with other lung diseases, such as lung cancer, emphysema, and tuberculosis. 
Amorphous silica has previously been considered less harmful than crystalline silica.  However, recent studies have shown that amorphous SNP has potential toxicity similar to that of crystalline particles. In addition to crystallinity, the physicochemical properties of SiNPs produce different toxicity in vitro and in vivo studies. Safety and potential adverse effects should be considered, especially those affecting the immune system.

Germany has begun talks with Senegal on gas extraction and LNG supplies. Mr. Scholz recently visited a solar farm in Dakar. He told a news conference that he was willing to work more closely with Senegal on renewable energy. Senegal's president told a news conference that his country was ready to supply liquefied natural gas to the European market.  

The global economy may be facing its greatest test since World War II amid the ongoing threats of COVID-19, the Conflict between Russia and Ukraine, heightened financial market volatility, and climate change, IMF Managing Director Kristina Georgieva warned in an article posted on the IMF's website.

Some 30 countries have imposed restrictions on trade in food, energy, and other key commodities since the outbreak of the Conflict, the article noted. That would raise trade barriers, disrupt global supply chains, drag down economic growth and undo years of economic gains. If countries let it go, the costs will be enormous and everyone will be affected.

The prices of many other commodities like the nano silica are expected to increase in the future. Luoyang Tongrun Nano Technology Co. Ltd.
