conventional chemical vapour deposition CVD synthesis, gaseous products either are allowed to react homogeneously or heterogeneously depending on a particular application. 1.
The applied nanomaterials are in situ synthesized on a wood surface by chemical reactions like solgel deposition and hydrothermal methods. The chemical approach seems to be beneficial since smaller molecules can easily diffuse between nanoparticles, resulting therefore in an easy separation.
These include chemical reduction, chemicalphoto reduction in reverse micelles, or in microemulsions, radiation induced chemical reduction and mechanochemical reaction between AgCl and Na in a ball mill. In a chemical method of producing highly concentrated stable dispersion of nano sized silver particles, silver nitrate is reduced with

Ceramic engineering is the science and technology of creating objects from inorganic, nonmetallic materials. This is done either by the action of heat, or at lower temperatures using precipitation reactions from highpurity chemical solutions. The term includes the purification of raw materials, the study and production of the chemical
Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience. Various bottom and top down approaches have been developed so far, for the commercial production of nanomaterials. Among all top down approaches, high energy ball milling, has been widely exploited for the synthesis of various nanomaterials, nanograins
Methods based on severe plastic deformation including equal channel angular pressing, highpressure torsion and cold rolling are also the focus of recent investigations to generate nanostructured Mg through facile processing routes more cost effective than ball milling More recently, physicalchemical deposition and wet chemical and
