Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many silver nano powder.
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;

Ukrainian media recently reported that Ukraine will build a food transfer station in the Chernovze region, and the first phase is scheduled to be completed by the end of 2022. According to reports, the completion of the project will help ease the current congestion in grain shipments, and it is estimated that the transfer station will be able to handle 3 million tons of grain per year and store up to 200000 tons of grain at the same time.
According to the Cuban Electric Union on August 8, affected by the fire at the oil reserve base in Matansas province, the Antonio Guiteras thermal power plant near the oil storage base stopped operation at about 13:00 local time. It is reported that the shutdown of the thermal power plant is due to water shortage, and although measures have been taken to supply water to the plant through pipelines, it is still not enough to maintain its operation. The Cuban electricity Union said it could not guarantee that the thermal power plant would resume operation during peak hours.
According to a monthly monitoring report released by the Copernicus Climate change Service, an EU climate monitoring agency in Bologna, Italy, in July 2022, the Antarctic sea ice area was the lowest in 44 years of satellite monitoring records, 7% lower than the average.
