Effects of Gamma Irradiation on Polyvinylidene Fluoride Thin Films

Effects of ion irradiation on conductijvity of CrSi2 thin films

Electrical resistivity measurements are used to study damage in CrSi2 thin films induced by Ne, Ar, or Xe ion irradiation over a fluence range of 10-10 ions cm• Irradiation produces a factor of 5-12 increase in film conductivity at the higher fluences. The influence of defect generation and recombination is evident. We speculate that formation of a compound defect is a dominant factor enhancing...

Effects of gamma irradiation on antioxidant activity of Ergosan

Background: The approaches chosen for control of Outbreaks of infectious diseases in Aquatic farming industry include improvement of environmental conditions, stocking of specific pathogen free (SPF) brood stockings, and application of vaccines and immunostimulants. Despite numerous studies on the effects of Ergosan on immune system of aquatic animals, there is no data available on ant...

Effects of UV irradiation treated polycarbonate substrates on properties of nanocrystalline TiO2 sol-gel derived thin films

In this study, in order to achieve effective coating of the homogeneous titanium dioxide (TiO2) thin film, UV irradiation pre-treatment was carried out to activate PC surfaces before coating. Sol-gel-based nanocrystalline TiO2 thin films were prepared by employing tetrabutyl-titanate as a precursor. Nanocrystalline TiO2 thin films were deposited by sol-gel spin coating on the treated substrates...

Ultrasound irradiation combined with hydraulic cleaning on fouled polyethersulfone and polyvinylidene fluoride membranes.

In this study, an ultrasonic irradiation technique was utilized to mitigate the fouling of polyethersulfone (PES) and polyvinylidene fluoride (PVDF) membranes. The use of ultrasound at 20 kHz was applied to a dead-end microfiltration cell in order to mitigate fouling caused by the presence of colloidal bentonite particles. The effect of ultrasonic power and pulse duration on the permeate flux r...
