Invited talk
The wide bandgap semiconducting oxide, ZnO is attractive for a range of optoelectronic devices due to its dual advantages of high optical transparency and electrical conductivity. In view of its applications, ZnO films have been grown by a variety of techniques and different methods of material engineering have been used to tailor its properties. In this study, we show the effect of varying...

Oral presentation
Preparing of polysulfone (PSF) gas separation membranes by dry/wet phase inversion technique were conducted in this work. The effect of evaporation time (ET) on the morphology, structure and gas separation performance of produced PSF membranes was investigated. The ET was varied for 0, 10, 30, 60, and 120 s. Morphology and structure of membrane samples were analyzed through the SEM micrograph...

Oral presentation
Eu-doped BaTiO$_3$ thin films were deposited on quartz and borosilicate glass substrates by a sol-gel spin coating process. The films were grown with various growth parameters including film thickness, spinning speed, annealing time, annealing temperature and concentration of europium to evaluate their influence on film luminescent properties. We studied their luminescent properties using...
