then the substance can acquire completely new properties. particles with sizes from 1 to 100 nanometers are usually " nanoparticles " is called for example, it turned out that nanoparticles of some materials have very good catalytic and adsorption properties. since many of the physicochemical properties of nanoparticles, unlike bulk materials, depend on their size, in recent years there has been great interest in methods for measuring the size of nanoparticles in solutions. nanoparticles nanoparticles particles of the order of nanometers, or nanoparticles, as they are called in scientific circles, have one property that greatly hinders their use. they can form agglomerates, that is, they stick together. since nanoparticles are promising in the fields of ceramics, metallurgy, it is necessary to solve this problem . one possible solution is to use dispersants such as ammonium citrate (aqueous solution), imidazoline, oleic alcohol (insoluble in water). methods of obtaining nanomaterials particles of …
