can anyone refer me to any site or book where i would get the properties of materials at nano scale and how they change with the change in the grain size?
Nanoparticles are tiny particles with at least one dimension less than 100 nanometers. They can be made from a variety of materials and have unique properties due to their small size.
Nanoparticles exhibit properties such as increased surface area, enhanced reactivity, and unique optical, electrical, and magnetic properties. These properties make them useful in a variety of applications.
Nanoparticles can be synthesized through various methods, including chemical precipitation, sol-gel synthesis, and physical vapor deposition. The method used depends on the desired properties and intended application of the nanoparticles.
Nanoparticles have a wide range of potential applications, including drug delivery, environmental remediation, electronics, and energy storage. They can also be used in cosmetics, coatings, and sensors.
Some studies have shown that certain nanoparticles may have negative impacts on human health and the environment. It is important to conduct thorough research and risk assessments before using nanoparticles in any application.
