567 یادداشت منتشر شده(Electrical Nanoparticles) Coating Agent or Stabilizer for The Simulation Process in Nano Reactor

Note: The coating or stabilizing agent produced nanoparticles stick together and form agglomerates due to their high specific surface area and surface energy. This phenomenon leads to the loss of properties resulting from the small size of these particles.
To prevent the aggregation of nanoparticles during the synthesis stage, stabilizers are used. Two types of methods are commonly used to stabilize nanoparticles, electrostatic and steric drift. In a model, two methods of stabilizing particles are used. In the first method, ions are used to stabilize nanoparticles. These ions are attracted to the particles and form an electrically charged layer around the nanoparticles, resulting in covalent Raman drift of particle aggregation. In the second method, macromolecules are used to stabilize nanoparticles. Macromolecules adhere to the surface of the particles and occupy space around the nanoparticles. As the particles approach each other, these molecules become entangled, and Raman is generated from the particles sticking together. It is from the interactions of the nano-layer and lipid as a function of the nanoparticle structure, morphology, and surface electrochemistry. This broad target consists of a number of nanomolecules, which is obtained from coarse-grained molecular simulations.

In the production of porous nanoparticles by the method of reducing the coating agent or stabilizing the nanoparticles, the spatial drift method is usually used to stabilize the particles. Stabilizers in this method are used as a stabilizing agent. They are most commonly used in coating nanoparticles. In the synthesis of nanoparticles, the reducing agent, the stabilizer, and the size of the nanoparticles are obtained. One of the parameters that greatly affects the size in the synthesis of nanoparticles is the concentration of the monitoring material, and the higher the concentration of the precursor, the larger the size of the produced particles, and conversely, the lower the concentration of the monitoring material , the smaller the particle size. There are different production concentrations and the effect of the monitoring material concentration on the size of the produced nanoparticles . By changing the concentration, the size of the nanoparticles is reduced to nanometers. In the case of nanoparticle synthesis and increasing the size of the produced particles, it increases from nanometers to micrometers.

Conclusion :
The effect of the amount of monitoring material in the synthesis of silver nanoparticles has been shown to increase the average particle size of the resulting particles by increasing the amount of nanometers. The nanoparticles synthesized at different concentrations do not change the identification of the nanoparticles by increasing the concentration of monitoring material, and the resulting nanoparticles are quasi-spherical. However, with increasing the amount of monitoring, the average particle size increases from nanometers to micrometers . On the other hand, with increasing the concentration of the precursor , the particle size increases; the resulting nanoparticles face an increase in volume.
