Şahin, Erdem; Yaşar Mahlıçlı, Filiz; Yetgin, Senem; Balköse, Devrim (Wiley, 2012-07)

In this study, the effect of activator ZnO and heating time at 190°C on foaming, gelation, and dehydrochlorination of poly(vinyl chloride) (PVC) plastisol was investigated. For this purpose, a PVC plastisol was prepared ...

Optical and surface properties of zinc oxide nanoparticles dried by conventional and supercritical ethanol drying techniques

Egbuchunam, Theresa Obuajulu; Yetgin, Senem; Özmıhçı Ömürlü, Filiz; Balköse, Devrim (Research India Publications, 2014)

Zinc oxide (ZnO) nanoparticles were synthesized by conventional (ZnO-A) and supercritical ethanol drying (ZnO-B). Nitrogen adsorption/desorption analyses were performed to determine the surface areas of the powders. The ...
