Surfactant Assisted Ball Milling: A Simple Top down

The unlimited applications of nanoparticles in human life are increasing day by day. Nanoparticles have drawn attention among researchers from academia to industry due to its large specific surface area, high chemical reactivity, physical affinity and interesting optical, electrical and magnetic properties. These properties of nanoparticles 14.7 Use of ball milling. Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces.

Sonochemical synthesis of silica particles and their size control

Silica particles were easily prepared by an ultrasound-assisted sol–gel method. •. The particle size was controlled by the ammonium hydroxide/water molar ratio. •. The size-controlled diameter of silica particles ranged from 40 to 400 nm. •. The particles were formed in a relatively short reaction time. tetraethyl orthosilicate.The synthesis of nanoparticles generally involves two main approaches, namely, the top-down and bottom-up approaches. The top-down approach involves methods such as sol–gel, spinning, chemical vapor deposition, pyrolysis, and biosynthesis, whereas the bottom-up process includes methods such as mechanical milling, nanolithography, Synthesis methods of nanoparticles and their key applications

Mechanochemical Synthesis of Nanoparticles for Potential

There are two main strategies for the synthesis of nanoparticles (NPs): top-down, and bottom-up [].In comparison to the bulk materials, NPs show unique properties such as tunable porosity, controllable particle size, and size-dependent properties, which make them attractive for various applications [2,3,4].The synthesis of NPs is usually Nanoparticle–polymer hybrids are becoming increasingly important because seemingly contrasting properties, such as mechanical stability and high elasticity, can be combined into one material.
