On the Electrochemical Reduction Mechanism of CaWO4 to W Powder

Erdogan, Metehan
Karakaya, İshak
The reduction mechanism of CaWO4 to W in molten eutectic CaCl2-NaCl electrolyte has been studied. Cyclic voltammetry and constant potential electrolysis tests were performed to determine the reversible cell potential. Analyses of the experimental results revealed that at least 2.2 V was required to compensate the potentials for the accompanying cell reaction and the electrode polarizations. A cell reaction was proposed by associating the experimental results and the Gibbs energy changes of the possible reactions.


The role of calcium ion on activated sludge biochemical and physical properties in phosphorus deficient growth medium
Aksu, Ceren; Sanin, Faika Dilek; Gültekin, Güzin Candan; Department of Biotechnology (2010)
Nutrients and cations have significant effect on activated sludge characteristics and therefore effect the efficiency of whole processes. To determine the properties in phosphorus deficient medium and the effect of calcium ions two reactor sets with two different phosphorus concentration (C/N/P=100/5/0.05 and C/N/P=100/5/1), three different concentrations of calcium (0.5, 5, 15 meq/L) were operated with 8 days of sludge residence time and an effective volume of 2 L. Results showed amount and composition of ...

Fickian diffusion of organic penetrants in glassy polymers is formulated as a moving‐boundary problem, and the effect of concentration‐dependent diffusivity on the concentration distribution is investigated. The solutions obtained for concentration‐dependent and constant diffusivity cases are compared. The results show that the concentration distribution curves differ both quantitatively and qualitatively. It is concluded that the sharp advancing boundary between the glassy and rubbery regions is due not on...
The Effect of Ultrasonication on the Size and Morphology of Iron Oxide - Chitosan Nano and Microparticles
Akin, Deniz; YAKAR, ARZU; Gündüz, Ufuk (2013-04-28)
The aim of this study is to synthesize magnetic Fe3O4-chitosan nano and microparticles (Fe3O4-CPs) by suspension cross-linking and ionic gelation methods and investigate the effect of ultrasonication on the size, morphology and magnetic properties. The synthesized particles were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and vibrating sample magnetometry (VSM). The results showed that the ultrasonication decreased the mean particle diameter and enhanced magnetic ...
A theoretical study on coenzyme Q(10) and its reduced form. AM1 treatment
Türker, Burhan Lemi (2000-01-01)
Coenzyme Q(10) (CoQ(10)) and its reduced form, ubiquinol (CoQ(10)H(2)) were subjected to semiempirical quantum chemical treatment at the level of AM1-RHF type calculations. Both of the structures are stable having negative total and binding energies and exothermic heats of formation. The frontier molecular orbital characteristics, electrostatic contour diagrams and charge distributions of these structures were presented.
Electrochemical Formation of Alloys of Scandium in Molten Salts
polat, çağlar; ERDOĞAN, METEHAN; iplikçioğlu, Safder; Karakaya, İshak (2018-02-01)
The Al-Sc alloy formation by the reduction of Sc containing compounds in a molten salt containing CaCl2 was investigated in this study. The preliminary tests revealed that Al3Sc intermetallic, which gives the superior properties to this alloy, was successfully formed and distributed homogeneously throughout the Al matrix. XRD, SEM-EDS and optical microscopy analyses were used to confirm the results.
