Silver nanoparticles powder are nanomaterials that are less than 100 nanometers in all three dimensions. The surface-to-volume ratio in nanoparticles has increased compared to bulk materials, resulting in different optical, electrical, and chemical properties than bulk materials. These materials are considered today because of their properties. You will need information on Expensive silver nanoparticles powder in Iran and Cheap silver nanoparticles powder. Or you may need information about Best silver nanoparticles powder for export. Stay with us.
Newest Methods of silver nanoparticles powder Producing
Regarding the latest methods available today for the production of these products, it can be said that in nanotechnology , particles with very small sizes and at the atomic scale are made, which is why they show new properties. Physical methods of producing nanoparticles require high energy, and chemical methods usually lead to the retention of some toxic reactants and the non-use of nanoparticles in biological applications. For this reason, in recent years, the biosynthesis of nanoparticles by plants and microorganisms, as a biocompatible and green method, has attracted the attention of many researchers.
The use of plant leaf and fruit extracts can be an alternative to the physical and chemical methods of producing nanoparticles and can be produced on a large scale and at a lower cost. For example, in Iran, which is one of the leading countries in this field, it can be said that oak is one of the dominant species in the west of the country and in Ilam province, which produces a large amount of its fruit every year and usually without using goes.
Therefore, studying the potential of oak fruit extract can be a solution for its effective use and a cheap and biocompatible way to produce nanoparticles. The study found that oak extract has a high potential for producing silver nanoparticles. The production of nanoparticles in this way was done in one step and at ambient temperature and the process was completed in a very short time. The intense color change of the solution from clear to dark brown, as well as the increase in the absorption of the solution due to the reduction of ions and their accumulation in the form of silver nanoparticles.
What is silver nanoparticles powder Made of?
As mentioned, nanoparticles are solid particles with dimensions of 1 to 100 nanometers. Nanoparticles are a set of atoms that are dimensionless. Nanoparticles come in a variety of shapes, including spherical, triangular, cubic, pentagonal, rod, and oval. If the size is reduced to the nanoscale, there will be significant changes in the physical properties of the compounds. As the surface-to-volume ratio of the particle increases, so do the electronic, optical, temperature, mechanical, and chemical reactivity properties of the compound.
In other words, increasing the surface-to-volume ratio in the particle causes the atoms on the surface to be more active than the atoms inside; as a result, the properties of the sample change. Also, the particle size in nanoparticles becomes smaller, and the atoms that are on the surface around them have fewer neighboring atoms than the mass compounds. As a result, there is less binding energy per atom of diameter. The result is a reduction in the binding energy of each atom, based on the Gibbs-Thomson equation, the reduction of the melting point and the radius of the particle.
Regarding the types of silver nanoparticles, the following can be mentioned:
- Silver nanoparticles contain silver halides
- Silver phosphate
- Silver oxide
- Silver sulfide and AgO
Silver halides are widely used in photography. By absorbing neon, these nanoparticles emit electrons and can regenerate silver ions. As a result, the image appears. Smaller nanoparticles cover the surface better and increase the resolution of the image.
