High Purity Nano Ag Silver powder cas 7440-22-4, 99%
The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports.
To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field.
Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935.
The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems. The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.
Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.
According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict.
Besides, affected by the ever-changing international situation, the supply and prices of international bulk silver nano powder are still very uncertain.
About Nano Silver Ag powder:
Ag is silver. Nano Silver, or ag nanoparticles, silver nanoparticles, is a metal Silver with a particle size of nanoscale.
Is Nano Silver healthy?
The size of the nanosilver is mostly about 25 nanometers, which has strong inhibition and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae and Chlamydia trachomatis, and will not produce drug resistance. Made of nanometer silver and combed cotton fiber, cotton socks have good antibacterial and deodorant effects.
Does Nano Silver kill germs?
In addition to being able to release silver ions, silver nanoparticles can themselves kill bacteria. Silver nanoparticles can accumulate in the pits that form on the cell wall after they anchor to the cell surface. The accumulated silver nanoparticles can cause cell membrane denaturation.
Does Nano Silver kill good bacteria?
Silver nanoparticles play an important role in the field of microelectronics because of their excellent electrical conductivity. Due to the surface effect and quantum size effect, silver nanoparticles also have some special applications, such as surface-enhanced Raman applications and medical applications.
Which is better nano silver or colloidal silver?
Colloidal silver cannot be used with other beneficial agents and has a weak effect on the biofilm. Therefore, it does not do a sufficient job protecting enamel and balancing the oral biofilm by reducing acid. Nano Silver can be used at much lower concentrations and can penetrate biofilms with ease.
Nanosilver is a powdered silver elemental, particle size is less than 100nm, generally between 25-50nm. The properties of silver nanoparticles are directly related to their particle size. Studies have found that the smaller the particle size, the stronger the bactericidal performance.
What are the side effects of nano silver?
Silver nanoparticles may be absorbed through the lungs, intestine, and through the skin into circulation and thus may reach such organs as the liver, kidney, spleen, brain, heart and testes. Nanosilver may cause mild eyes and skin irritations. It can also act as a mild skin allergen.
Silver Nanopower/Nanopower is a versatile substance with pharmacological, antimicrobial, conductive and chemical uses. Nanopower is dissolved in a variety of solvents, including water, ethanol and isopropyl alcohol, to produce a convenient suspension. Research continues to reveal new applications for silver nanoparticles in areas such as biotechnology, medicine, electronics and manufacturing, where they often achieve the same end result as more expensive solutions.

Features of Nano Ag Silver powder cas 7440-22-4:
Silver nano powder or Ag powder is a kind of metallic silver with nano scale particle size.
Most of the nano silver has a particle size around 25 nm. According to the tests on Animals, there is no exhibition of being poisoned even if the dosage of silver nanoparticles is thousands of times used more than the standard dose.
Meanwhile, it helps to repair the damaged epithelial cells. What worth to be mentioned is that the antibacterial effects of Ag nanoparticles become more enhanced when in water, which is more effective to the treatment of diseases.
The experts believe that this nano silver anti-bacterial nanopowder can be widely used in the field of environmental protection, textiles and clothing, fresh fruit, food and health.
How is Nano Ag Silver powder produced?
There are many ways to prepare nano-silver, including the physical crushing method, vacuum condensation method and mechanical ball milling method. Chemical methods are reduction method, electrochemical reduction method, photoreduction method, gas-liquid two-phase method, hydrothermal synthesis method, precipitation method synthesis method, etc. The preparation methods of silver nanoparticles are gradually mature, and the cost and production efficiency have reached the level of large-scale industrial production. It can be predicted that as a new material, nano-silver particles will have a very broad development prospect in the fields of medicine, biology, environment and so on.
Applications of Silver nano powder:
Nanosilver particles (NSPs), are among the most attractive nanomaterials and have been widely used in a range of biomedical applications, including diagnosis, treatment, drug delivery, medical device coating, and personal health care.
What is nano silver used for?
Nanosilver is made up of silver nanoparticles. These particles serve as antibacterial and antifungal agents for industrial purposes, in water treatment, and in consumer products (such as clothing, cosmetics, childcare items, food containers, and many others).
1. The nano silver powder can be used as a pharmaceutical antibacterial, disinfectant;
2. Some of countries use Ag Nanoparticles for anti-AIDS drugs, mixed with zinc oxide powder for disinfection;
3. The silver metal powder used as a chemical catalyst.
4. Also, The nano silver powder used as Antivirus antibacterial material: adding 0.1% silver nanoparticles, the inorganic antibacterial powder, can play an important role in the suppression and killing of dozens of pathogenic micro-organisms such as Escherichia coli, Staphylococcus aureus.
5. Silver nanoparticles as a new anti-infective product which has broad-spectrum, non-resistance, free from the pH effects, antibacterial, durable, non-oxidized black and many other properties, Ag Nanoparticles can be widely used in medical, household fabrics and health care supplies.
6. Adding nano silver powder as antibacterial, anti-corrosion coating paint materials can also be used successfully in the construction and preservation of relics.
Manufacturers produce household items that utilize the antibacterial properties of silver nanoparticles. These products include nano-silver lined refrigerators, air conditioners and washing machines.

Albemarle, the world's largest lithium producer, said it would have to close its plant in Langelsheim, Germany if the EU designated lithium as a hazardous material. The European Commission is currently evaluating a proposal by the European Chemicals Agency (EHCA) to classify lithium carbonate, lithium chloride, and lithium hydroxide as hazardous to human health.
As a result, Albemarle will no longer be able to import lithium chloride, its main raw material, putting its entire plant in Langelsheim at risk of closure, Albemarle chief financial Officer Scott Tozier said. According to Tozier, the plant has annual sales of about $500 million and a forced closure would have a significant impact on Albemarle's operations.
Industry sources said that listing lithium as a hazardous substance would place an additional burden on the silver nano powder, please feel free to contact us and send an inquiry.
