Applications of Silver Dichromate

Posted on by adminLeave a comment

silver dichromate is a colorless, insoluble compound that decomposes with hot water and has an anion charge of -2. It is a versatile and widely used chemical with important applications in chemistry, biology and medicine.

Microcrystallization of silver dichromate

An improved method for the microcrystallization of silver dichromate is presented, which enables continuous suspension of forming crystals in their “mother liquor” by rotation of a stoppered test tube while in a horizontal position during cooling. This technique is extremely effective for producing crystals of optimum size and perfection in very difficult cases, and holds promise generally in similar applications.

Photocatalytic activity of as-prepared Ag2CrO4 nanoparticles

The photocatalytic activity of the as-prepared Ag2CrO4 and Ag2Cr2O7 nanostructures was studied by performing photooxidation of methyl orange (MO). XPS spectra indicated the high purity of these as-prepared Ag2CrO4 nanotepheric compounds. These compounds are potentially useful in the catalytic oxidation of benzylic and allylic alcohols by refluxing benzene, which requires an active oxygen atom to reduce the reaction product.

Nano silver is a kind of new antibacterial agent, which has strong bacteriostatic and bactericidal action

Posted on by adminLeave a comment
What is nanosilver? Nano silver is used as a particle size to make nano metallic silver elemental. The nano silver particle size is generally 25 nanometers. It is extremely small in size and has a large surface area. Because of this, it can have significant quantum size effects and quantum tunneling effects. It also has super activity and permeability. It is hundreds of thousands times more bactericidal then ordinary silver. Nano-scale metallic silver has a surface electronic characteristic that allows it to form ligands with hydrophobic, amino, and other electron-absorbing group on bacteria protein molecules. This enhances the antibacterial effects. Nano silver is an innovative antibacterial agent. It has a strong antibacterial effect and broad spectrum.
What role does nano-silver play?
Silver nanoparticles can be made from silver nanoparticles. These particles can be used in industrial applications, water treatment, as well as consumer products like clothing and cosmetics. Silver nanoparticles are a silver element with a nanometer size. Nano silver is a form of powder-silver element. The particle size is typically between 25-50nm. The size of silver nanoparticles directly affects their properties. It was discovered that smaller particles have stronger bactericidal performances.
Nano-silver can kill bacteria
Silver is an antiseptic which has been proven to kill bacteria and fungi as well as viruses. Positively charged silver (Ag+)22,22 is responsible for the antibacterial effect. Silver ions have many modes of action to target microorganisms.
The nanoparticles of silver cannot be seen by the naked eye. Nano silver antibacterial solution is made by introducing a small amount of nano-silver into deionized drinking water. It is extremely small in particle size, 500 to 1000 times smaller that a cell. Because it is so easily absorbed and excreted, all bacteria, viruses, and fungi are quickly and efficiently trapped. It is not the same as ordinary antibiotics. While antibiotics can kill some bacteria, they cannot kill viruses. Nano silver can kill over 650 bacteria and viruses. It should be considered the body’s second immune defense system.
Is nano-silver healthy?
Silver found in the environment can be considered safe because it is a compound. Although the environmental and health hazards of silver nanoparticles remain poorly understood, colloidal silver can be deemed unsafe to consume.
Nano silver can be used to kill bacteria. It causes no skin irritation and has no toxic effect on cells. This opens up new opportunities for the widespread use of nano-silver as an antibacterial agent. It is the latest generation in natural antibacterial agents.
Is nano-silver dangerous?
Nano silver can cause minor irritation to the eyes and skin. It is also mildly allergenic to the skin. Silver nanoparticles inhaled can cause damage to the lungs, liver, and spleen. Studies have shown that silver particles can be genotoxic for mammalian cells.

Nano silver solution broad-spectrum sterilization

Posted on by adminLeave a comment
For thousands of years silver has been used to make jewelry and human utensils. According to science, silver can be sterilized and disinfected. Silver’s antibacterial effects are due to the absorption of silverions by microorganisms. The microorganisms responsible for breathing are those that are attracted to silver ions. The enzyme will stop working after being destroyed. Nano-silver uses cutting-edge technology to create nano-sized silver. The quantum leap in the bactericidal power of silver in nano-state has been made possible by nano-technology. Nano-silver is very potent in killing bacteria. More than 700 types can be killed by broad-spectrum sterilization, which does not require any drug resistance. This is a new generation of natural antibacterial agents that is safe, effective, and causes no irritation.
Silver ions not only have the function of destroying bacterial proteins, but also have a super function-sterilization, and relatively little harm to heavy metal silver. Silver ions can be destroyed by small amounts of bacteria when there is a small amount.
The sterilization principles of super-nano silver
Principle 1: Super nano-silver-nanotechnology processing silver particles, its activity becomes stronger, and silver ions are released after contact with water, and the active silver ions can enter the cell wall of bacteria freely, causing the cell wall to rupture and the cytoplasm to flow out of the bacteria to die instantly;
Principle 2: The silver ions attract the negatively charged microbial cellular cells and then combine with the functional groups of the catalytic systems to cause the bacteria to stop respiration, metabolism, and reproduction. To sterilize the organism until death.
Silver can kill bacteria using these two mechanisms (including super bacteria) and it will not give rise to drug resistance.

Colloidal Silver Bulk

Posted on by adminLeave a comment

colloidal silver bulk is a high grade dietary supplement that has been used successfully to support the body’s immune system for over thirty years. It is gentle, easy-to-drink, and highly effective for supporting the body’s natural defences against colds and flu.

It has an excellent safety profile when taken as directed and is not known to interfere with medication or cause side effects. It is suitable for the whole family and has a growing worldwide consumer following.

The only way to know what you are getting in a colloidal silver product is to test it for yourself!

Our colloidal silver is made in a GMP-compliant lab using specialized equipment that yields extremely small, nano-sized silver particles. Unlike ions that can react with other compounds in the gut and form silver chloride–becoming much less effective, stable silver particles remain intact and work by attacking germs directly.

A study published in 2019 found that nano silver was as effective as steroids and immune-suppressing drugs for reducing inflammation and skin infections like eczema and psoriasis. It can also be used to combat other skin conditions such as acne and contact dermatitis.

In some people, too much silver can accumulate in the tissues over months or years and cause a blue-gray tint to the skin, eyes, organs and nails that is called argyria. This condition does not usually cause serious health problems but can be painful and may last permanently.

We recommend only taking a very low dosage of colloidal silver and never taking it while you are on antibiotics or thyroid medication. These medicines can make colloidal silver more or less effective and may cause negative side effects if taken in high doses.

Why is nano-silver good for you? The benefits of using nano-silver in various industries such as pharmaceuticals, healthcare, and consumer goods.
These nanoparticles can be very tiny particles, with sizes from 1 to 100 nanometers. Nanosilver is composed of Silver nanoparticles. These nanoparticles are useful as antibacterial or antifungal agents in the industry, water treatment, consumer goods, as well as for cleaning clothing, cosmetics and food containers. In some filter systems to purify groundwater, silver nanoparticles can also be used.

What does silver colloid consist of?
Coloidal silver and silver solution both contain silver nanoparticles that are suspended in liquid bases.

Are you allowed to eat colloidal Silver?
When taken orally, silver accumulates in the body. The silver can build up in your body for many months, causing your skin, eyes and internal organs to turn bluish. It’s called “argyria” by doctors. It is permanent.
Only in very rare circumstances, colloidal silver may cause seizures and other serious side effects.
It is possible for colloidal silver to interact with certain prescription drugs such as penicillamine, Depen, Quinolone Antibiotics and tetracycline.

Colloidal Silver is good to your health.
The ability to kill bacteria through the destruction of proteins makes colloidal silver useful for wound dressings. However, silver is neither a useful mineral nor has any known functions in the body. The skin can turn permanently blue if it is taken orally. Brain function issues can also be caused by oral silver.
While colloidal silver has been proven effective in treating infections, hay fever and skin conditions among other ailments, it is not supported by any scientific research. It is currently not possible to prove the effectiveness of colloidal sodium in treating COVID-19. The use of colloidal silver in the treatment of COVID-19 is not recommended.
The scientific evidence is not in support of the treatment with colloidal Silver dietary supplements for any type of disease.

About Silver Telluride Ag2Te Powder:
The chemical formula of silver telluride Ag2Te.Molecular weight 343.34.Grey cubic crystal or powder.Melting point 955℃, relative density 8.5.Soluble in nitric acid, ammonia and potassium cyanide solution, insoluble in water.

Silver telluride is a telluride compound of silver, also known as silver disilver telluride or silver telluride (I). It forms a monoclinic crystal. Broadly, silver telluride may be used to denote AgTe(silver (II) telluride, a metastable compound) or Ag5Te3. Silver telluride (I) occurs naturally as hard manganese ore, while (II) silver telluride is known as queen ore. Silver telluride is a semiconductor that can be doped with N-type and P-type. Stoichiometric Ag2Te has N-type conductivity. When heated, silver is lost from the material. Non-stoichiometric silver telluride exhibits remarkable magnetoresistance.

Silver telluride is fairly stable in air and insoluble in water, dilute acids other than nitric acid, and potassium cyanide solutions; When it is heated to 300 ~ 600℃, some of it decomposes to produce “wool silver”. Rmcplant is a trusted global Silver Telluride Ag2Te Powder supplier.

Silver TellurideAg2Te99.99%-100 mesh343.348.5 g/cm3Gray Black

 

How is Silver Telluride Ag2Te Powder Produced?
Silver telluride process: Produced by the interaction of silver with tellurium at high temperatures (to volatilize excess tellurium) and in a flow of hydrogen gas.

Silver telluride is obtained by heating silver and tellurium together in a vacuum container until reddish. Or from the reaction of tellurium with a hot solution of silver nitrate. In addition, the H₂ TE and soluble silver salt solution reaction can also make silver telluride.
 
Applications of Silver Telluride Ag2Te Powder:
The utility model relates to a vertical-cavity surface-emitting laser containing silver telluride/silver zinc telluride core-shell quantum dots and a preparation method thereof. The vertical cavity surface emitting laser comprises a quartz substrate arranged upward in sequence, a lower high mirror, a silica layer containing silver telluride/silver zinc telluride core-shell quantum dots and an upper high mirror.

Single crystal Ag2Te nanowires with uniform dispersion were synthesized. A series of X-ray diffraction (XRD) and scanning electron microscopy (SEM) characterization showed that the Ag2Te sample has a controllable morphology, good crystallinity and high purity nanostructure, the diameter of which is about 200nm, the length of which can reach tens of microns. More importantly, the associated electrical properties of a single Ag2Te nanowire. It is found that the I-V curves of the samples are symmetric and non-linear at room temperature by in-situ electric field assembly and voltammetry measurement. During the heating process, the I-T curve is accompanied by the phase transition, and the current also changes greatly. These experimental results lay a good foundation for further research on the electrical transport performance of nanostructured devices in the future.
