Emulsifier-free cationic latexes based on vinylbenzyl chloride and 2-(dimethylamino)ethyl methacrylate with adjusted hydrophilic-hydrophobic properties
Türk, Hayrettin; Karabacak, R. Bengü; Erdem, Murat (Wiley-Blackwell, 2015)Functional emulsifier-free cationic latexes based on styrenic monomer vinylbenzyl chloride (VBC) and acrylic monomer 2-(dimethylamino)ethyl methacrylate (DMA) were successfully prepared with dual quaternary ammonium ions ... -
Emulsifier-free poly[2-(diethylamino) ethyl methacrylate] microgels with cationic quaternary ammonium monomers
Karabacak, R. Bengü (Wiley-Blackwell, 2016)Although poly[2-(diethylamino) ethyl methacrylate] (PDEA) microgels are biocompatible and show potential in drug delivery, little research exists with respect to their preparation. Therefore, emulsifier-free PDEA microgels ... -
Enhanced catalytic activity of o-iodosobenzoate in poly[(styrylmethyl)hexadecyldimethylammonium chloride] latexes for the hydrolysis of p-nitrophenyl diphenyl phosphate
Karabacak, R. Bengü; Erdem, Murat; Türk, Hayrettin (Elsevier Science BV, 2011)Six 5.0 mol% crosslinked poly[(styrylmethyl)hexadecyldimethylammonium chloride] latexes containing 8-67% quaternization were synthesized via two-stage process and used as supports for o-iodosobenzoate (IBA) catalyst in the ... -
Facile two-step preparation of polystyrene/anatase TiO2 core/shell colloidal particles and their potential use as an oxidation photocatalyst
Karabacak, R. Bengü; Erdem, Murat; Yurdakal, Sedat; Çimen, Yasemin; Türk, Hayrettin (Elsevier Science Sa, 2014)Titania and materials containing titania have received considerable attention due to their technological importance in many areas. In this study, anatase crystalline titania (TiO2) coated polystyrene (PS) colloidal particles ... -
Latexes with Hexadecyl Group on Their Quaternary Ammonium Ions as Catalytic Media for the Hydrolysis of Paraoxon by o-Iodosobenzoate
Karabacak, R. Bengü; Türk, Hayrettin (Taylor & Francis Inc, 2012)The micelle-mimetic poly[(styrylmethyl)hexadecyldimethylammonium chloride] latexes were used as media and supports for o-iodosobenzoate (IBA) catalyst in the hydrolysis of paraoxon (PO). The latex particles contained 16-67 ... -
Oxidation of Thymol and Carvacrol to Thymoquinone with KHSO5 Catalyzed by Iron Phthalocyanine Tetrasulfonate in a Methanol-Water Mixture
Günay, Tugce; Çimen, Yasemin; Karabacak, R. Bengü; Türk, Hayrettin (Springer, 2016)The oxidation of thymol and carvacrol to thymoquinone with potassium peroxymonosulfate (KHSO5) catalyzed by iron phthalocyanine tetrasulfonate (FePcTS) in a methanol (4.0 mL)-water (0.5 mL) mixture has been carried out. ... -
Preparation of novel antimicrobial polymer colloids based on (+)-usnic acid and poly(vinylbenzyl chloride)
Karabacak, R. Bengü; Tay, Turgay; Kıvanç, Merih (Elsevier Science BV, 2014)A novel antimicrobial colloidal system based on (+)-usnic acid, an important natural antimicrobial molecule, and poly(vinylbenzyl chloride) (PVBC) colloids was synthesized. The chloromethyl functionality on poly(vinylbenzyl ... -
Preparation of PS Colloids with DMA and MMA Comonomers and Suitability of P(S/DMA) for Colloidal Silica Deposition
Karabacak, R. Bengü; Türk, Hayrettin (Taylor & Francis Inc, 2012)There is a lack of investigation on the effects of hydrophilic comonomer and pH on the particle size of functionalized polystyrene colloids. In this study, polystyrene (PS) colloids were prepared via emulsifier-free emulsion ... -
Sorption of lead ions from aqueous solution onto Enterococcus faecium biomass
Cankılıç, Meral Yılmaz; Karabacak, R. Bengü; Tay, Turgay; Kıvanç, Merih (Iwa Publishing, 2013)This study reports kinetics and equilibrium of lead sorption onto the biomass of Enterococcus faecium. E. faecium is a lactic acid bacterium and was isolated from meat. Batch experiments were carried out to analyze the ...
