Crystalline structure of gold
WebNanoparticles can have a regular crystalline structure, can be amorphous, or can form a pseudoclose packing undescribable by any of the crystallographic space groups. For each of these structural states of a nanoparticle, there is a certain set of numbers of the atoms involved in the particle that corresponds to optimum stable configurations. WebApr 8, 2024 · Various characterisations were performed which confirmed synthesis of spherical-shaped silver nanoparticles of size ranging between 10 and 50 nm with FCC crystalline structure. The main bioactive agent, namely biopolyphenols, such as “rutin” and various other flavonoids, were responsible for reduction of silver ions into nanoparticles.
