Characterization of Nanomaterials

The chemical composition and structure of nanomaterials are the key factors that determine their properties and applications. Characterization and testing technology is the fundamental way to scientifically identify nanomaterials, recognize their diverse structures, and evaluate their special properties. It is also an indispensable technical means for the healthy and sustainable development of the nanomaterials industry. The main purpose of the characterization of nanomaterials is to determine some of the physical and chemical characteristics of nanomaterials, such as morphology, size, particle size, chemical composition, crystal structure, band gap width, and light absorption characteristics, etc. rnAlfa Chemistry’s nanotechnology scientists are highly experienced in providing a range of advanced techniques to study nanomaterials.
