The recent visit by US House Speaker Nancy Pelosi has boosted US-Taiwan relations at a time of increasing tension between Washington and Beijing. She vowed that the United States would protect Taiwan's democratic autonomy. "The United States is still determined to safeguard Taiwan's democracy," she said in a meeting with Taiwan's president, Tsai Ing-wen.

Pelosi's visit to Taiwan sparked anger in Beijing, which denounced Pelosi's visit as "extremely dangerous" to geopolitical stability. After Pelosi's visit, Beijing conducted the largest-ever military exercise near Taiwan, encircling the island with live-fire rockets and ballistic missiles. In addition, China announced that it would stop cooperation and dialogue with the United States on issues such as climate and cross-border crime prevention, indicating Beijing's intention to fight back against the United States over what it believes to be interference in China's affairs.

But perhaps most importantly for the business community, recent events have exacerbated the showdown between China and the US in the most important area of the global economy: semiconductor chips. The Sino-US chip battle, which has been brewing for years, has now reached a critical crossroads, experts say, as the two superpowers compete for technological and economic dominance. The world's chipmakers may soon be forced to choose between Washington and Beijing.

Because of the turbulent international situation, the supply and prices of many international bulk nano silica are still very uncertain.

Nano silica or nano SiO2 is a very important new inorganic material. It is amorphous white powder, non-toxic, tasteless, and non-polluting. It has the advantages of small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion and special properties in thermal resistance and resistance. Nano-silica plays a very important role in industrial application and scientific research because of its excellent stability, reinforcement, thickening and thixotropy.
 
Nano silicon dioxide structure is a quasi-granular spherical structure with reticular and flocculent shape. This special structure makes silicon dioxide have unique chemical and physical properties. The reflectivity of nano-silica to ultraviolet radiation less than 490 nm is more than 70%. Although it is often used as an anti-sedimentation agent and dispersant in the ink industry, it can also resist ultraviolet aging and thermal aging.
 
Nano silica still has the characteristics of high strength, toughness and stability at high temperature. when dispersed in the ink and combined with the macromolecular chain of the resin in the ink, the three-dimensional network structure can be formed. in order to improve the storage stability and printing adaptability of the ink.
 
The size effect and macroscopic quantum tunneling effect of nano-silica cause its silting effect, which can infiltrate near the unsaturated bond of the resin and form a hybrid effect with the electron cloud of unsaturated bond. improve the thermal, optical and chemical stability of polymer materials.
 
Nano silica has a three-dimensional network structure, large specific surface area and high activity, which can form a network structure when the ink is dry, increase the strength and finish of the ink, improve the suspension of the pigment, and keep the color of the pigment unchanged for a long time. If nano-silicon dioxide is added, the can opening effect of the ink can be obviously improved, so that it is not delaminated, and it has thixotropy, anti-flow hanging and good printability.
 
Therefore, whether nano-silica is used as an additive or a modified material, it is of great significance for the low cost of the ink industry, especially how to produce nano-sized ink adapted to the digital printing speed and fineness.
 
Nano silica used in polyamide ink
At present, the ink industry uses alcohol-soluble polyamide resin instead of alcohol-soluble polyamide resin, which uses dimer fatty acid as a monomer and adds isobutyric acid to introduce branched chain on the polyamide main chain, so as to improve the alcohol solubility of the resin and its stability in alcohol solvents. However, there are some shortcomings in the quality of alcohol-soluble polyamides, such as darker color, poor transparency, low gloss, poor solubility of alcohols than benzene, and serious gelation. The nano-silica particles were fully dispersed into the polyamide ink system through the sand mill. Due to the small size effect of the nano-silica, the viscosity of the polyamide decreased, the ink film formed was flexible and non-stick, and the wear resistance was better. The printing adaptability has been effectively improved.
 
Nano silica used in cooking-resistant composite ink
The role of nano-silica in the cooking-resistant composite ink is mainly to maintain the good fluidity and fineness of the ink to prevent pigment settlement; when printing, it can improve the flow and hanging performance of the ink film when printing on the machine, and prevent the occurrence of water lines; when coating, it is beneficial to the uniform coating of the adhesive, avoid the generation of air bubbles and improve the composite fastness. Due to the high fluidity and small size effect of nano-silica, the surface of the material is more compact and smoother, the friction coefficient becomes smaller, coupled with the high strength of nanoparticles, the wear resistance of the material is greatly enhanced. In addition, nano-silica has a better anti-aging effect on inks used for outdoor decoration, advertising and other printing products, and it can effectively reflect ultraviolet rays. After being added to the resin, it can greatly reduce the degradation of ultraviolet rays on the resin and improve the sun resistance of printed products, thus delaying the aging of materials. Therefore, for ink resin, the addition of nano-silica makes its anti-aging, friction resistance have been greatly improved, and also has the effect of anti-sticking and anti-sinking.

New Delhi: India is seeking to increase its purchases of crude oil from Brazil, the country's oil minister said recently after meeting his Brazilian counterpart.  

India is the world's third-largest importer and consumer of crude oil. Brazil currently supplies only a fraction of India's crude oil imports.  

India's state-owned companies Bharat Petroleum Corp and Oil and Natural Gas Corp have invested in oil and gas exploration in Brazil.  

India, which imports about 84% of its crude oil needs, is reducing its import bill by increasing biofuel use, among other things.  

India's state-owned fuel retailers are increasing ethanol storage capacity by 51 percent and the country plans to double the biofuel blend in petrol to 20 percent by 2025.  

India and Brazil are currently cooperating on biofuels and ethanol.

The prices of many commodities like the nano silica are expected to increase in the future.
