In this study, shear flocculation of chromite from mixtures of chromite and serpentine was investigated. The effects of zeta potential, contact angle, stirrer speed, flocculation (stirring) time, settling time and concentration of sodium oleate, Na2SiO3 and Na2SiF6 were tested. Control of zeta potential was the key factor for selective aggregation. Experiments carried out at optimum conditions yielded a concentrate (settled material) assaying 44.6% Cr2O3 with a recovery of 81.0% and selectivity index of 9.70 from a mixture containing 29.4% Cr2O3.

Shear flocculation of chromite fines in sodium oleate solutions
Akdemir, U; Hicyilmaz, C (1996-05-01)
In this study, chromite fines were aggregated by stirring after the particle surfaces were made hydrophobic with sodium oleate. The effects of pH, sodium oleate concentration, stirrer speed and flocculation time were examined. Electrokinetic potential and contact angle measurements were also carried out to interpret the flocculation in terms of surface charge and particle hydrophobicity.
Immobilization of invertase in conducting polypyrrole/PMMA-co-PMTM graft copolymers
Yildiz, HB; Kiralp, S; Toppare, Levent Kamil; Yagci, Y (Wiley, 2005-04-15)
In this study, invertase was immobilized in copolymer electrodes constructed. Three different types of polymethyl methacrylate-co-polymethyl thienyl methacrylate matrices were used to obtain copolymers that were characterized by FT-IR spectroscopy. Immobilization of enzymes was carried out by the entrapment of the enzyme in conducting polymer matrices during electrochemical polymerization of pyrrole through thiophene moieties of polymers. Immobilization of the enzyme was achieved by application of 1.0 V con...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT)
Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01)
In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
Electrochromic properties of a soluble conducting polymer of 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole
Tarkuc, S.; Sahmetlioglu, E.; Tanyeli, Cihangir; Akhmedov, I. M.; Toppare, Levent Kamil (Elsevier BV, 2007-02-20)
In this study, synthesis of a thiophene functionalized monomer, 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole (SNBS) was achieved. A new polythiophene derivative was synthesized by both chemical and electrochemical polymerization. The polymer synthesized via chemical oxidative method was soluble in organic solvents and characterized by nuclear magnetic resonance (H-1 and C-13 NMR) spectroscopy. The average molecular weight of the chemically synthesized polymer was determined by gel permeation chromatography (G...
Sequential Deposition of Electrochromic MoO3 Thin Films with High Coloration Efficiency and Stability
Turel, Onur; Hacioglu, Serife O.; Coskun, Sahin; Toppare, Levent Kamil; Ünalan, Hüsnü Emrah (The Electrochemical Society, 2017-01-01)
Effect of thin film deposition route on the morphology and performance of molybdenum oxide (MoO3) based electrochromic devices was investigated. For the deposition of thin films, a sequential deposition method, which includes ultrasonic spray pyrolysis (USP) and thermal evaporation methods was used. Films deposited solely using either USP or thermal evaporation method were used as control samples. Following deposition, MoO3 thin films were then characterized using X-ray diffraction, X-ray photoelectron spec...
