Use of plant materials for the synthesis of nano minerals is easier and advantageous as this method is simple and is having upper hand as it follows single step synthesis procedures, one pot synthesis, easy product recovery from the final solutions, eco-friendly, compatible to pharmaceutical and biomedical applications, cost effective, economic viability, nontoxic, less time consuming, and no need to maintain
The gas phase method is one of the main preparation methods of nano-Al2O3, and its refinement is a variety of specific preparation methods. The main technical principle of laser-induced vapor deposition is to produce high-temperature environment by laser, so that the related nano-materials react chemically in a very short time to produce embryos that are invisible to the naked eye.
A novel method for rapid preparation of Bi 2 Te 3 nano-sized powders with an average particle size of about 70 nm was developed. A starting powder mixture consisting of Bi 2 Te 3 coarse particles of 5 mm was ground using cryogenic grinding in the liquid nitrogen.
Precipitation Method. Precipitation method is a general method used to prepare submicron particles of poorly soluble drugs.[ 13 15] In this method, drug is dissolved in solvent and then solution is mixed with solvent to which drug is insoluble in the presence of surfactant. Rapid addition of solution to such solvent (generally water)
