Changing Behavior and Structure in Nanoparticles (Based on Nano-Micro-Electronics PHD) Educational-Research PhD

Researcher  and author PhD student:   Afshin Rashid

Note: The structural change in nanoparticles is a prefix that shows minus nine power, that is, one billion. Here it means that the nanometer is used for the length. The behavior of particles of  one nanometer with a very short length corresponds to one billionth of 1   meter, one millionth of 1  millimeter, or one thousandth of 1  micrometer.

Many methods have been developed for the production of nanoparticles or nanostructured particles, which include steam, liquid, and solid state processes.

In general, chemical reactions to produce nanoparticles can occur

Each of the solid, liquid and gas states. A common method of producing materials in solids is by crushing the particles, increasing their contact surface  , and then increasing the mixture to increase the penetration of the atoms  of the violins at high temperatures. In chemistry, the so-called substances with which chemical reactions begin are called reactants, and the substances that are turned into during the reaction  are called products. Reactors can be solids, liquids, or gases. They themselves are an independent element or can be in the form of multi-component compounds. Multi-component compounds are commonly called precursors.

Molecular bonds, which are usually formed by the bonding of molecules to metal electrodes, are able to reduce the dimensions of molecular devices. These connections have a high potential to behave similarly to common electronic components. These molecular devices can be a good alternative or supplement to common technologies and create new capabilities in these technologies.

Conclusion : 

Nanoparticles are used as ingredients in many applications in various fields. These functions include electronic, magnetic, optical, and electrical materials.
