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 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. The average fiber diameter for boron doped and undoped fiber mats were 204 and 123 nm, respectively. Also, grain diameters of boron doped and undoped nanocrystalline sintered powders were measured as 140 and 118 nm, respectively. The BET results showed that boron undoped and doped Bi2O3-La2O3 nanocrystalline powder ceramic structures sintered at 800 degrees C have surface areas of 59.72 and 39.80 m(2)/g, respectively.

Synthesis and characterization of boron-doped Bi2O3-La2O3 fiber derived nanocomposite precursor Durmusoglu, Senol; Uslu, Ibrahim; TUNÇ, TUNCAY; Keskin, Selda; Aytimur, Arda; Akdemir, Ahmet (Springer Science and Business Media LLC, 2011-11-01) 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 increas...
Fabrication and characterization of boron doped BaZrO3 nanofibers via an electrospinning technique TUNÇ, TUNCAY; Uslu, I.; Keskin, Serhat (2011-10-01) In this study, boron doped and undoped poly(vinyl) alcohol/zirconium-barium acetate (PVA/Zr-Ba) nanofibers were prepared using an electrospinning technique then calcinated at three different temperatures; 250 degrees C, 500 degrees C, 800 degrees C for 2 h. The originality of this study is the addition of boron to metal acetates. The fibers were characterized by FT-IR, DSC, XRD and SEM. The addition of boron did not only increase the thermal stability of the fibers, but also increased their diameters, which...
Synthesis of heterocyclic unit substituted carbazole derivatives and their electrochemical polymerization Oğuztürk, Hatice Esra; Önal, Ahmet Muhtar; Tirkeş, Seha; Department of Polymer Science and Technology (2013) The study comprises synthesis of 3,6 and 2,7 substituted carbazole derivatives. Substitution was done by furan groups. The main purpose to conduct this study is to synthesize new low band gap donor-acceptor type monomers and analyze the differences stem from the substitution site difference and alkyl chain effect attached to the nitrogen atom. For this aim, four monomers; 3,6-Di(2-furyl)-9H-carbazole (3,6-F-Cz-F), 3,6-Di(2-furyl)-9-ethyl-carbazole (3,6-F-N-et-F), 2,7-Di(2-furyl)-9-H-carbazole (2,7-F-Cz-F) ,...
The Synthesis of Complex Polymer Electrolytes Based on Alginic Acid and Poly(1-vinylimidazole) and Application in Tyrosinase Immobilization Kartal, Muejgan; Kayahan, Senem; Bozkurt, Ayhan; Toppare, Levent Kamil (Springer Science and Business Media LLC, 2009-01-01) In this study, proton conducting polymer electrolyte networks consisting of alginic acid (AA) and poly(1-vinylimidazole) (PVI) were prepared. The polymer networks were obtained by mixing AA and PVI with several stoichiometric ratios, x (with respect to monomers). Polymer networks were characterized by FT-IR spectroscopy and their compositions were investigated by elemental analysis (EA). Enzyme entrapped polymer networks (EEPN) were produced by immobilization of tyrosinase in the AA/PVI matrix during comple...
Synthesis and Characterization of Conducting Copolymers of Bisphenol A-Diglycidyl Ether with Thiophene Side-Groups and Pyrrole Sahmetlioglu, Ertugrul; Varol, Ramazan; Toppare, Levent Kamil; Yuruk, Huseyin (Informa UK Limited, 2009-01-01) Copolymers of bisphenol A-diglycidyl ether with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization. Bisphenol A-diglycidyl ether with thiophene side-groups (DGEBATh) was obtained from the reaction between bisphenol A-diglycidyl ether (DGEBA) and thiophene-3-acetic acid. The syntheses of copolymers of DGEBATh and pyrrole were achieved electrochemically using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylam...
