The experimental conditions for the synthesis of sub-micrometre, spherical particles of calcium hydroxyapatite [Ca,,(PO,),(OH),] (HA) and tricalcium phosphate [Ca,(PO,),] (TCP) are investigated through chemical coprecipitation from the aqueous solutions of calcium nitrate and di-ammonium hydrogen phosphate salts. The precipitation process employed was also found to be suitable for the production of sub-micrometre HA/TCP composite powders in situ. The synthesized pure HA and TCP powders were found to be stable even at 1300 degrees C in air for prolonged heating times. Bioceramic sample characterization was achieved by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and density and surface area measurements. Crystallographic analyses of HA powders were performed by the Rietveld method on the powder XRD data.

AN EXPERIMENTAL INVESTIGATION OF POLYVINYL-CHLORIDE) EMULSION POLYMERIZATION - EFFECT OF INITIATOR AND EMULSIFIER CONCENTRATIONS ON POLYMERIZATION KINETICS AND PRODUCT PARTICLE-SIZE
Karakaş, Gürkan (Wiley, 1989-01-01)
Effects of concentration changes in initiator species Na2SO3, (NH4)2S2O8 and CuSO4, and emulsifier, ammonium stearate, on poly(vinyl chloride) (PVC) emulsion polymerization kinetics and on product particle size were experimentally investigated. It was observed that to obtain industrially significant rates and overall conversions, not only an optimum concentration ratio of Na2SO3/(NH4)2S2O8/CuSO 4 must be used, but also the concentrations of these species must be above certain limits. Increasing the concentr...
An integrated process for partial oxidation of alkanes
Zhou, XP; Yılmaz, Ayşen; Yilmaz, GA; Lorkovic, YM; Laverman, LE; Weiss, M; Sherman, JH; McFarland, EW; Stucky, GD; Ford, PC (Royal Society of Chemistry (RSC), 2003-09-21)
The partial oxidation of alkanes via bromination followed by the reaction with solid metal oxide mixtures (MO) is shown to give an array of products that can be tuned by varying the MO and the reaction conditions.
A comparative study of electrocoagulation and coagulation of aqueous suspensions of kaolinite powders
Kilic, Mehtap Guelsuen; Hoşten, Çetin (2010-04-15)
Removal of kaolinite particles from their synthetically prepared suspensions was studied by electrocoagulation and coagulation to investigate the effect of such operating parameters as initial pH, coagulant dosage, applied voltage, current density, and time. Coagulation was more effective in a wider pH range (pH 5-8) than electrocoagulation which yielded optimum effectiveness in a relatively narrower pH range around 9, where, in both methods, these pH values corresponded to near-zero zeta potentials of kaol...
A THERMODYNAMIC STUDY OF THE SYSTEM MGCL2-NACL-CACL2
Karakaya, İshak (1986-10-01)
The reversible EMF for the formation of MgCl2 in fused salts containing NaCl and CaCl2 was studied with a view to furthering the understanding of electrolytes of use in industrial magnesium electrolysis. Measurements were carried out in a cell with pure chlorine gas and Mg-Bi alloy as active electrode materials. The data were used to infer the Gibbs energy of mixing, the enthalpy of mixing and the entropy of mixing. These properties were used with other data to construct the liquidus surface of the ternary ...
Synthesis and characterization of conducting graft copolymers based on oligophenols
Sahmetlioglu, Ertugrul; Arikan, Ufuk; Toppare, Levent Kamil; Yuruk, Huseyin; Mart, Hasan (Informa UK Limited, 2006-10-01)
Oligo-2-aminophenol (OAF) was synthesized with oxidative polycondensation of 2-aminophenol and hydrogen peroxide in an aqueous alkaline medium at 80 degrees C. Oligo-2-aminophenol with thiophene side groups (TOAF) was obtained by the reaction of OAF and thiophene-3-acetic acid. Graft copolymers of TOAF and pyrrole were synthesized by electrochemical polymerization in p-toluene sulfonic acid (PTSA)/water medium. Characterization of the graft copolymer (TOAF-g-Py), was carried out by combination of techniques...
