Note: Nanoreactors are made up of nanoparticles, and the first effect of reducing particle size is to increase surface area. Increasing the surface area to volume ratio of nanoparticles causes the atoms located on the surface to have a much greater effect on the physical properties of the particles than the atoms within the particle volume.
This feature greatly increases the reactivity of nanoparticles. The structure of nano-reactors is one of the properties of nanoparticles, the high surface area to volume ratio of these materials. Using this property, powerful catalysts can be produced in nanometer sizes. These nano-catalysts greatly increase the efficiency of chemical reactions and also significantly prevent the production of waste materials in reactions. The use of nanoparticles in the production of other materials can increase their strength or reduce their weight. It increases their chemical and thermal resistance and changes their reaction to light and other radiation. By using nanoparticles, the strength-to-weight ratio of composite materials will increase greatly. In smart nano-reactors , the concept of nano - assemblies is summarized in all the information and codes necessary to produce an object similar to itself. We have a very small machine that knows how to produce its own likeness , which in nanoscience is referred to as a "nano-assembler".
Nanoreactors are defined as any structure with one or more dimensions and are measured in the nanometer range. Nanostructures refer to materials or structures that have at least one dimension between 1 and 100 nanometers . The importance of the nanoscale is in changing the properties and characteristics of materials at these dimensions. Properties such as electrical conductivity, electromagnetic properties, etc. The beginning of changing the properties of materials by miniaturizing them depends more than anything on the type of material and the desired property. For example, as the dimensions of a material are reduced , generally some of the electromagnetic properties of nanomolecular materials such as the conductivity of nanoparticle particles in the material improve. This increase in strength does not only occur in the range of a few nanometers, and the strength of a material of several tens or even hundreds of nanometers may be much greater than that of a large-scale bulk material. On the other hand, changes in some properties such as conductivity in nanoreactors and electromagnetic properties in nanowires may occur at dimensions of only a few nanometers.
Conclusion:
Nanoreactors are made up of nanoparticles, and the first effect of reducing particle size is to increase surface area. Increasing the surface area to volume ratio of nanoparticles causes atoms located on the surface to have a much greater effect on the physical properties of the particles than atoms within the particle volume.
