Zeolite framework stabilized copper(I) oxide nanoparticles (4.8 +/- 2.6 nm) were prepared for the first time by using a four step procedure: the ion exchange of Cu(2+) ions with the extra framework Na(+) ions in Zeolite-Y, the reduction of the Cu(2+) ions within the cavities of zeolite with sodium borohydride in aqueous solution, the dehydration of Zeolite-Y with the copper(0) nanoclusters, and the oxidation of intrazeolite copper(0) nanoclusters by O(2) at room temperature. Zeolite stabilized copper(I) oxide nanoparticles were thoroughly characterized by ICP-OES. XRD, HR-TEM. Raman, XPS, UV-vis spectroscopy and N(2) adsorption-desorption technique.

Microstructural investigation of Cu2+ doped nanohydroxyapatites Evis, Zafer (Informa UK Limited, 2010-05-01) Pure and Cu2+ doped nanohydroxyapatites were synthesised by a precipitation method to investigate the effect of Cu2+ ions on the structure of hydroxyapatite (HA) and its thermal stability after the air sintering at 1100 degrees C. A small amount of CaO was observed in the Cu2+ doped HAs after the X-ray diffraction results. The addition of Cu2+ changed the hexagonal lattice parameters of the HA and resulted in smaller grain size after sintering at 1100 degrees C. The addition of Cu2+ ions into HA resulted in...
Synthesis and characterization of conducting copolymers of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester and their electrochromic properties Ertas, M; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-07) A new dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and butanedioyl dichloride. Electrochemical behavior of this monomer, succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) was studied. Homopolymerization was achieved by chemical and constant Current electrolysis methods. Copolymerization of SM with thiophene was performed by constant potential electrolysis in acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) and dichloromethane (DCM)-TBAFB, solvent-electroly...
Formation of TiB2 by volume combustion and mechanochemical process Bilgi, Eda; ÇAMURLU, HASAN ERDEM; Akgun, Baris; Topkaya, Yavuz Ali; SEVİNÇ, NACİ (Elsevier BV, 2008-04-01) Titanium diboride was produced both by volume combustion synthesis (VCS) and by mechanochemical synthesis (MCP) through the reaction of TiO2, B2O3 and Mg. VCS products, expected to be composed of TiB2 and MgO, were found to contain also side products such as Mg2TiO4, Mg3B2O6, MgB2 and TiN. HCl leaching was applied to the reaction products with the objective of removing MgO and the side products. Formation of TiN could be prevented by conducting the VCS under an argon atmosphere. Mg2TiO4 did not form when 40...
Synthesis of a regular polymer containing pseudo-polyether cages Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2005-04-20) A new compound consisting of 2-thienyl units linked by polyether bridge has been synthesized and its electrochemical polymerization was performed via constant potential electrolysis (CPE) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in CH3CN. Chemical polymerization was carried out using FeCl3 as oxidizing agent. It is found that both methods gave the same polymer product without any cleavage of the polyether bridge between thiophene (Th) rings. Al...
Synthesis of aromatic poly(pyridinium salt)s and their electrochromic properties Keshtov, M. L.; UDUM, YASEMİN; Toppare, Levent Kamil; Kochurov, V. S.; Khokhlov, A. R. (Elsevier BV, 2013-05-15) Synthesis of a series of new conjugated electrochromic polymeric pyridinium salts containing main-chain triphenylamine and their electrochromic properties were demonstrated. All polymers exhibit intense UV absorptions at 336-338 nm in DMF and 340-343 nm in thin film form and fluorescence centered at 410-438 nm in DMF and 460-461 nm in thin film form. The electrochromic properties of the films were investigated by electrochemical and spectroelectrochemical methods. Reversible redox signals with stable electr...
