Abstract

Metallic colloids are frequently used in industry and provide understanding of science at microns to nanometers scales along with their applicability for various technologically important applications. Present investigations deal morphology-structure of gold, silver and their binary composition while processing the certain amount of their solutions in a newly designed process and tap opportunities of developing tiny shaped particles. At tuned ratio of pulse OFF to ON time and when gold solution was processed, several tiny shaped particles developed at solution surface. Such tiny particles deal force at the tip of each converted structure of smooth element under the steady-state immersing behavior pointing toward common centre to pack for developing different geometric anisotropic shaped particles. Under identical parameters along with pulse time, processing solutions of silver nitrate and binary composition of chloroauric acid-silver nitrate result into develop tiny particles having no specific shape where their packing deal mixed behavior of force resulting into develop distorted particles. Elongation and deformation of gold and silver atoms while in different structures is because of the plastically-driven behavior of electrons as per stretching of their clamped energy knots. In structure of three-dimensional where electrons of atoms do not deal transition require for elongation they retain the structure as it is known in hcp structure or two-dimensional structure. Different nature of precursors along with morphology-structure of particles is discussed in this paper opening abundant avenues of research.
