There are several primary synthesis platforms used in nanotechnology:
Chemical Vapor Deposition (CVD): In this method, gaseous reactants are used to produce solid materials. It's particularly useful for creating high-purity, high-performance carbon nanotubes and graphene. Sol-Gel Process: This technique involves the transition of a system from a liquid 'sol' into a solid 'gel' phase. It is commonly used for producing metal oxide nanoparticles and aerogels. Hydrothermal Synthesis: Conducted in aqueous solutions at high temperatures and pressures, this method is effective for creating nanocrystals and nanowires. Ball Milling: A mechanical process that grinds bulk materials into nanopowders. It is a cost-effective method for producing nanocomposites. Electrochemical Deposition: This method involves the reduction of metal ions from a solution to form a thin film on a conductive surface. It is widely used for creating nanostructured coatings.
