Advance Nanomaterials

Nano materials are defined as materials with at least one external dimension in the size range from approximately 1-100 nanometers. Nanoparticles are objects with all three external dimensions at the nanoscale1. Nanoparticles that are naturally occurring (e.g., volcanic ash, soot from forest fires) or are the incidental by products of combustion processes (e.g., welding, diesel engines) are usually physically and chemically heterogeneous and often termed ultrafine particles. Engineered nanoparticles are intentionally produced and designed with very specific properties related to shape, size, surface properties and chemistry. These properties are reflected in aerosols, colloids, or powders. Often, the behaviour of nanomaterials may depend more on surface area than particle composition itself. World demand for nanomaterials will rise more than two-and-a-half times to $5.5 billion in 2016. Nanotubes, nanoclays and quantum dots will be the fastest growing types. The energy storage and generation and construction markets will offer the best growth prospects. China, India and the US will lead gains among countries Nanoparticales
