Disclosed is a method of preparing self-assembled monolayers on a metal comprising electrolyzing a thiosulfate compound in a solvent, where the electricity for the electrolysis is applied at a voltage for a period of time.

Electrochemically directed self-assembly of monolayers on metal

A method of forming a porous silica film includes the following steps: a) providing a substrate; b) coating, on a surface of the substrate, a layer of charged polyelectrolyte; and c) applying an aged silica-bearing non-colloidal solution to the coated surface of the substrate to adsorb porous silica thereon. The adsorption cycle of steps (b) and (c) is repeated a number of times to control film thickness. The age and concentration of the silica-bearing solution are selected to control the porosity and the index of refraction of the porous silica film.

Preparation of thin silica films with controlled thickness and tunable refractive index

A two-step adsorption process for producing ordered organic/inorganic multilayer structures is provided. Multilayered films are formed on metallic and nonmetallic substrates by alternate adsorption of a cationic polyelectrolyte and anionic sheets of a silicate clay. The two-step adsorption process is not only fast but allows also for preparation of multilayer elements of thicknesses greater than about 2200 Angstroms on silicon, and greater than about 1500 Angstroms on gold, silver, and copper.
