Researcher and author: Dr. ( Afshin Rashid)
Note: The concept of nano_assembler molecular assembly As a device that can conduct chemical reactions by placing reactive molecules with atomic precision, such a set can create any desired molecule with high selectivity and efficiency. In order to produce significant amounts the molecular assembly must be able to reproduce itself. Once enough assembler has been formed, it can be reprogrammed to produce the required product.
In the concept of molecular assembly, nano_assembler amplified nanoparticles stick together to form a mass due to their specific surface area and high surface energy. This phenomenon leads to the loss of properties due to the small size of these particles. Stabilizers are used to prevent the accumulation of nanoparticles in the synthesis stage. Usually, two types of electrostatic and spatial drift methods are used to stabilize nanoparticles. In the first method, ions are used to stabilize nanoparticles. These ions are adsorbed to the particles and form an electrically charged layer around the nanoparticles, and as a result, the molecular drift of the produced nanoparticles due to the specific surface area and high surface energy, stick together and form a mass. This phenomenon leads to the loss of properties due to the small size of these particles. Stabilizers are used to prevent the accumulation of nanoparticles during the synthesis step. Usually, two new methods, electrostatic and spatial drift, are used to stabilize nanoparticles. You see a pattern of two methods of stabilizing particles. In the first method, ions are used to stabilize nanoparticles.
In the second method, large molecules are used to stabilize the nanoparticles. Large molecules adhere to the surface of particles and occupy space around the particle. As the particles get closer to each other, these molecules become entangled and prevent the particles from sticking together, preventing the particles from accumulating. In the second method, large molecules are used to stabilize the nanoparticles. Large molecules adhere to the surface of particles and occupy space around the particle. As the particles get closer to each other, these molecules become entangled and prevent the particles from sticking together. In the propagation of nanoparticles by electrostatic reduction method, molecular drift method is usually used to stabilize the particles. One of the most influential parameters on size in the electrostatic synthesis of nanoparticles is the concentration of the precursor. The higher the concentration of the precursor, The larger the particle size produced, and conversely, the lower the precursor concentration , the smaller the particle size.
Conclusion :
The concept of nano_assembler molecular assembly As a device that can conduct chemical reactions by placing reactive molecules with atomic precision, such a set can create any desired molecule with high selectivity and efficiency. In order to produce significant amounts the molecular assembly must be able to reproduce itself. Once enough assembler has been formed, it can be reprogrammed to produce the required product.
