The African Development Bank will finance $25 billion by 2025 to support Africa's fight against climate change, the bank's president said at the bank's annual meeting in Accra, Ghana.
He noted that climate change has had many negative impacts on the continent, causing natural disasters such as droughts, cyclones, and floods. Climate change costs Africa between $7 billion and $15 billion a year. "Africa has no choice but to address climate change."
To ensure Africa's food supply, the African Development Bank has delivered climate-friendly seeds to 12 million farmers in 27 countries in the past two years under the "Technology for Agricultural Change in Africa" program, he said.
In the area of renewable energy, the African Development Bank is implementing a $20 billion "Desert Power" initiative in the Sahel that is expected to power 250 million people, he said.
US President Joe Biden recently wrapped up his five-day trip to Asia with a summit of leaders of the "Quad" security Dialogue.
Biden has promoted a number of economic and security cooperation initiatives during his visit aimed at deepening ties with Indo-Pacific Allies and partners in response to China's growing influence in the region. Some analysts in the United States believe the most significant announcement may be an initiative to share maritime information to combat illegal activities. But other experts say Biden's move sets a good framework for more security cooperation, though it remains to be seen whether concrete action will follow.
Affected by several factors, the supply of the Titanium Dioxide TiO2 Powder,Overview of Titanium Dioxide TiO2 Powder, Application of Titanium Dioxide TiO2 Powder,Titanium dioxide TiO2 powder price,Titanium oxide TiO2 powder supplier is erratic and thus its prices are expected to go higher in the future.
Overview of Titanium Dioxide TiO2 Powder
Titanium dioxide is an inorganic substance with the chemical formula TiO2. It is a white solid or powdered amphoteric oxide. The molecular weight was 79.9. It is non-toxic, has the best opacity, the best whiteness and brightness, and is considered one of the best white pigments in the world.
Among the commonly used white pigments, titanium dioxide has the smallest relative density, and among the white pigments of the same quality, titanium dioxide has the largest specific surface area and the largest pigment volume. Titanium dioxide has very stable chemical properties and is an acidic amphoteric oxide. At room temperature, it hardly reacts with other elements and compounds. Ineffective for oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide. Insoluble in water, fat, dilute acid and inorganic acid, alkali, only soluble in hydrofluoric acid. . But under the action of light, titanium dioxide can undergo continuous redox reactions and has photochemical activity. This photochemical activity is particularly evident under the action of UV-anatase titanium dioxide.
Titanium dioxide is widely used in paint, chemical fiber, cosmetics, paper, ink, plastic, rubber, food and other industries. It has a high melting point and is also used in the manufacture of refractory glass, glazes, enamels, clays, high-temperature laboratory utensils, etc.
Titanium dioxide is used in food pigments (E171). Like all food colorings, its technical role is to make food more visually appealing, to color previously colorless food, or to restore food to its original appearance.
Jelly, fried food, cocoa products, chocolate, chocolate products, hard candy, polished candy, gum-based candy, puffed food, coating of candy chocolate products, mayonnaise, salad dressing, jam, solid beverages, konjac gel food, meat Soups, sauces, salads, and seasoned sandwiches may contain titanium dioxide.
Application of Titanium Dioxide TiO2 Powder
The most important applications of titanium dioxide are paints, varnishes, and paper and plastics, which account for around 80% of world titanium dioxide consumption. Other pigment applications, such as printing inks, fibers, rubber, cosmetics and food, account for another 8%. The rest are used in other applications such as technically pure titanium, glass and glass ceramics, electrical ceramics, metallic copper, catalysts, electrical conductors and chemical intermediates.
1. Titanium dioxide has become the most widely used white pigment due to its brightness and high refractive index.
2. Powdered titanium dioxide is also an effective sunscreen. It is used as a pigment to provide whiteness and opacity in products such as paints, coatings, plastics, paper, inks, food, pharmaceuticals (such as tablets and pills) and most toothpastes. In painting, it is often abbreviated to "lively white," "perfect white," "whitest white," or other similar terms.
3. Titanium dioxide is used as a colorant in the rubber industry, and also has the functions of reinforcement, anti-aging and filling.
4. Add titanium dioxide to white and colored rubber products, it is resistant to sunlight, no cracking, no discoloration, high stretching ratio, and acid and alkali resistance.
5. Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber floors, gloves, sports equipment, etc., generally anatase type.
6. In the production of automobile tires, a certain amount of rutile titanium dioxide products are often added to enhance the ability of anti-ozone and anti-ultraviolet rays.
7. Titanium dioxide is also widely used in cosmetics. Since titanium dioxide is non-toxic and far superior to lead white, almost all powdered titanium dioxide can replace lead and zinc white.
8. For permanent whitening, just add 5%-8% titanium dioxide powder, the fragrance is smoother, the adhesion is strong, the absorption is strong, and the covering power is strong.
9. Titanium dioxide in gouache and cold cream reduces greasiness and clarity.
10. Titanium dioxide is also used in many other perfumes, sunscreens, soaps, white soaps and toothpaste.
11. When deposited as a thin film, the refractive index and color of titanium dioxide make it an excellent reflective optical coating for dielectric mirrors.
12. Certain grades of modified titanium-based pigments are used in foam coatings, plastics, topcoats and cosmetics - the particles of these artificial pigments have two or more layers of different oxides (usually titanium dioxide, iron oxide or oxides) . aluminium), which can produce sparkling, iridescent and/or pearlescent effects.
13. Titanium dioxide is used in cosmetics and skin care products as pigments, sunscreens and thickeners, and as sunscreen and anti-ultraviolet pigments.
14. As a sunscreen, it uses ultra-fine TiO2, which is known for its combination with ultra-fine zinc oxide. It is considered an effective sunscreen that reduces the incidence of sunburn and minimizes the effects associated with long-term use. Early photoaging, photocarcinogenic and immunosuppressive sun exposure. extra semester. Sometimes these UV protectants are used in sunscreens along with iron oxide pigments to enhance protection against visible light.

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash. After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.
After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.

Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.
"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.
He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path... I believe it with all my heart."
Besides, because of the ever-changing international situation, the supply and prices of international bulk Titanium Dioxide TiO2 Powder,Overview of Titanium Dioxide TiO2 Powder, Application of Titanium Dioxide TiO2 Powder,Titanium dioxide TiO2 powder price,Titanium oxide TiO2 powder supplier are still very uncertain.
