Oil refineries and other industrial enterprises generate a large amount of sewage contaminated with petroleum products. Sewage must be treated before it can discharged into water body. treatment methods often do not allow reducing the content products to maximum allowable values. This is because microheterogenous system characterized by variable composition high stability. It thus important stu...

In this work, thermo-optical properties of gold nanoparticle colloids are studied using continuous wave (CW) laser irradiation at 532 nm. The nanoparticle colloids are fabricated by 18 ns pulsed laser ablation of pure gold plate in the distilled water. The formation of the nanoparticles has been evidenced by optical absorption spectra and transmission electron microscopy. The nonlinear optical ...
