Development of antibacterial electrospun chitosan/poly(vinyl alcohol) nanofibers containing silver incorporated HAP nanoparticles
Çelebi, Hande; Gürbüz, Mevlüt; Koparal, Ali Savaş; Doğan, A. (European Conference on Composite Materials, ECCM, 2012)Chitosan/poly(vinyl alcohol) (CS/PVA) nanofibers with a diameter in the range of 60-80 nm were produced by electrospinning method. The effect of CS/PVA blend ratio and process parameters on the morphology of fibers was ... -

Electrochemical treatment of water containing dye-stuffs: Anodic oxidation of congo red and xiron blau 2rhd
Ülker, B.; Koparal, Ali Savaş (1992)Removal of Congo Red and Xiron Blau 2RHD from their aqueous solutions has been carried out in a trickle tower electrochemical reactor. The effects of initial dye concentration, applied potential and solution flow rate on ... -
Removal of chromium from aqueous solutions and plating bath rinse by an electrochemical method
In this work, a bipolar packed bed electrolytic cell having steel Raschig rings behaving as electrodes has been used to remove chromium in the form of Cr(VI) from aqueous solutions and a sample of plating bath rinse. ... -
Removal of Dye Stuffs from Waste Water: Electrocoagulation of Acilan Blau Using Soluble Anode
An attempt was made to remove a dye such as Acilan Blau usingan electrochemical method. In the process a bipolar packed bed electrochemical reactor consisting of soluble electrodes was used and operated in the batch mode. ... -
Thermal characterization and flammability of polypropylene containing sepiolite-APP combinations
Kaynak, Elif; Üreyen, Mustafa Erdem; Koparal, Ali Savaş (Walter De Gruyter GMBH, 2017)The effects of sepiolite on fire behavior of ammonium polyphosphate-based intumescent flame retardant (IFR)/polypropylene (PP) were investigated. The disaggregation of sepiolite bundles has been provided by wet-milling as ...
