Boron doped poly(vinyl) alcohol/ bismuth - lanthanum acetate (PVA/Bi-La) nanofibers were prepared by electrospinning using PVA as a precursor. The effect of boron doping was investigated in terms of solution properties, morphological changes and thermal characteristics. The fibers were characterized by FT-IR, XRD, SEM and BET. The addition of boron did not only increase the thermal stability of the fibers, but also their diameters, which yielded stronger fibers. XRD analyses showed that boron doping increased the peak intensities and indicated that the boron doping enhanced the crystallite size. Moreover, no shifts were noticed in diffraction angles for boron doped and undoped samples. Therefore, boron doping did not significantly alter the lattice spacing. The SEM micrograph of the fibers showed that the addition of boron resulted in the formation of cross linked bright surfaced fibers. Also, grain diameters of boron doped and undoped nanocrystalline sintered powders were measured as 170 nm and 120 nm respectively. The BET results show that boron undoped and doped Bi2O3-La2O3 nanocrystalline powder ceramic structures sintered at 800 A degrees C have surface areas of 20.44 m(2)/g and 12.93 m(2)/g, respectively.

Preparation of Gadolina Stabilized Bismuth Oxide Doped with Boron via Electrospinning Technique TUNÇ, TUNCAY; Uslu, Ibrahim; Durmusoglu, Senol; Keskin, Selda; Aytimur, Arda; Akdemir, Ahmet (Springer Science and Business Media LLC, 2012-01-01) In this study, boron doped and undoped poly (vinyl) alcohol/bismuth-gadolina acetate (PVA/Bi-Gd) nanofibers were prepared using electrospinning technique then calcinated at 800 degrees C for 2 h. The originality of this study is the addition of boron to metal acetates. The effects of boron doping were investigated in terms of solution properties, morphological changes and thermal characteristics. The characteristics of the fibers were investigated with FT-IR, XRD, SEM and BET. The addition of boron did not ...
Synthesis and electropolymerization of 5,12-dihydrothieno[3 ',4 ': 2,3][1,4]dioxocino[6,7-b]-quinoxaline and its electrochromic properties Ak, Mine Sulak; Ak, Metin; Guellue, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2007-08-01) Synthesis of a new thiophene-based monomer; 5,12-dihydrothieno[3',4':2,3][1,4]dioxocino[6,7-b]quinoxaline (DDQ), was realized. The chemical structure of the monomer was characterized by H-1 NMR, FTIR and mass spectroscopy techniques. Electrochemical polymerization of DDQ and characterization of the resulting polymer [P(DDQ)] was performed. Moreover, the spectroelectrochemical and electrochromic properties of the polymer film were investigated. P(DDQ) has a low oxidation potential (0.9 V) and low band gap (1...
SYNTHESIS AND CHARACTERIZATION OF POLY(DICHLOROPHENYLENE OXIDE)S BASED ON THE ELECTROOXIDATION OF BIS(2,4,6-TRICHLOROPHENOXO)BIS(PYRIDINE)COPPER(II) COMPLEX SEN, S; KISAKUREK, D (Elsevier BV, 1993-01-01) Electroinitiated polymerization of bis(2,4,6-trichlorophenoxo)bis(pyridine)copper(II) complex was achieved in dimethylformamide by constant potential electrolysis under air and N2. The polymers obtained at several potentials were characterized by H-1 n.m.r., C-13 n.m.r., FTi.r. and d.s.c., and were found to be branched. The kinetics of the polymerization were followed by in situ cyclic voltammetry measurements at 13.5 and 20-degrees-C during electrolysis. As found for the thermal polymerization of this comp...
Synthesis, characterization and electrochromic properties of a conducting copolymer of pyrrole functionalized polystyrene with pyrrole Tarkuc, S; Sahin, E; Toppare, Levent Kamil; Colak, D; Cianga, I; Yagci, Y (Elsevier BV, 2006-03-08) A well-defined polystyrene (PSt) based polymer containing at one end-chain 3.5-dibromobenzene moiety. prepared by atom transfer radical polymerization (ATRP), was modified in two reaction steps. First one constitutes a Suzuki coupling reaction between aromatic dibromine functional polymer and 3-aminophenylboronic acid, when a diamino-containing intermediate was obtained. The second step is a condensation reaction between the diamino functional polystyrene and 2-pyrrole alclehyde. Thus, a polymer containing ...
