Preparation of lead free BZT-BCT thin films by chemical solution deposition and their characterization
Çeltikçi, Barış; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2012)
In the presented thesis, lead-free Ba(Ti0.8Zr0.2)O3-(Ba0.7Ca0.3)TiO3 (BZT-BCT) thin films were deposited on Pt/TiO2/SiO2/Si substrates using chemical solution deposition method and then the effect of process parameters were investigated to obtain optimum parameters of these lead-free thin films. The phase was selected near to the morphotropic phase boundary (MPH) to increase the number of polarization directions where rhombohedral and tetragonal phases exist together. In this study, the effect of sintering ...
Dehydration of aqueous aprotic solvent mixtures by pervaporation
Sarıalp, Gökhan; Kalıpçılar, Halil; Yılmaz, Levent; Department of Chemical Engineering (2012)
Aprotic solvents are organic solvents which do not easily react with a substance dissolved in it and they do not exchange protons despite of their high ion and polar group dissolving power. Therefore, this characteristic property makes aprotic solvents very suitable intermediates in many industries producing pharmaceuticals, textile auxiliaries, plasticizers, stabilizers, adhesives and ink. Dehydration of these mixtures and recirculation of valuable materials are substantial issues in industrial application...
Coordination polymerization of cyclic ethers by metal xanthates and carbamates
Taş, Hüseyin; Alyürük, Kemal; Department of Polymer Science and Technology (2003)
Zinc xanthates are active catalysts in stereoregular polymerization of propylene oxide and markedly more stable than that of known classical stereoregular catalysts. But steric control of zinc xanthates is weaker. To find more effective catalyst systems the isopropyl xanthates of Cu, Pb, Ni, Fe, Al and Sn are investigated and only copper (Cu(isoPr)Xt) and tin (Sn(isoPr)Xt) isopropyl xanthates were appeared to be active, but Cu(isoPr)Xt yielded only low molecular weight product. Therefore Sn(isoPr)Xt system ...
Selenium, nickel, and calcium levels in cancerous and non-cancerous prostate tissue samples and their relation with some parameters
Celen, Ilker; MÜEZZİNOĞLU, TALHA; Ataman, Osman Yavuz; BAKIRDERE, Sezgin; KORKMAZ, MEHMET; NESE, NALAN; Senol, Feriye; Lekili, Murat (2015-09-01)
In the present study, tissue samples of patients with cancerous and non-cancerous prostate were analyzed for their Se, Ni, and Ca contents. Possible relationship between Se, Ni, and Ca concentrations and some parameters including preoperative prostate-specific antigen (PSA) levels, histopathological neurovascular invasion, extra-capsular extension, seminal vesicle invasion, positive surgical margins, PSA relapse after radical prostatectomy, and total Gleason scores were obtained. Inductively coupled plasma ...
