Laser surface patterning by Contact Particles Lens Arrays (CPLA) has been widely utilized for patterning of smooth surfaces but there is no technique developed by which CPLA can be deposited on a rough surface. For deposition of CPLA, conventional techniques require the surface to be flat, smooth and hydrophilic. In this study, a new method for the deposition of CPLA on a rough surface is proposed and utilized for patterning. In this method, a hexagonal closed pack monolayer of SiO2 spheres was first formed by self-assembly on a flat glass surface. The formed monolayer of particles was picked up by a flexible sticky surface and then placed on the rough surface to be patterned. A Nd:YVO4 laser was used to irradiate the substrate with the laser passing through the sticky plastic and the particles. Experimental investigations have been carried out to determine the properties of the patterns.

The treatment of the surface of sensitive equipment and components, cotaminated by chemical agents is an important issue for the safety of population and security of structures. Material TiO2/SiO2 prepared and dispersed in a solvent system of ethanol/iso propanol/diethoxy methane has the good treatment with chloroethyl ethyl sulfide (2-CEES) on the surface of sensitive equipment and components. Treatment capacity depends on the tested surface and the number of treatments. Treatment capacity decreases from flat glass surface sensitive component surface pular rubber surface chlorobutyl rubber surface. The treatment does not affect the performance of sensitive components.
