Two new isostructural open-framework zeotype transition metal borophosphate compounds, (H)(0.5)M-1.25(H2O)(1.5)[BP2O8].H2O (M=Co(II) and Mn(II)) were synthesized by mild hydrothermal method. The structure of compounds were characterized by single-crystal X-ray diffraction which have ordered, alternating, vertex-sharing BO4, PO4, and (MO4)OM(H2O)(2) groups with hexagonal, P 6(1) 2 2 (No 178) space group and unit cell parameters for Co a= 9.4960(6) angstrom, c= 15.6230(13) angstrom, for Mn a= 9.6547(12) angstrom, c= 15.791(3) angstrom, Z=1 for both of them. TGA/DTA analysis, IR spectroscopy were used for characterization. Magnetic susceptibility measurements for both of the compound indicate strong antiferromagnetic interaction between metal centers.

COMPOSITION VARIATIONS OF LATTICE-PARAMETERS OF TLIN(SE1-XTEX)2, TLIN(SE1-XSX)2, AND TLIN1-XGAXSE2 MIXED-CRYSTALS Hasanlı, Nızamı; CULFAZ, A (Wiley, 1995-01-01) TlInSe2 and TlInTe2 crystallize in a tetragonal cell (space group 14/mcm) (Muller et al.). A primitive cell of these ternary crystals contains two formula units. All the Tl atoms in these compounds are univalent. The In atoms are trivalent being in a tetrahedral environment consisting of Se or Te atoms. InSe4 or InTe4 fragments of a unit cell form the chains extended along c-axis coinciding with [001] directions. Such chains are bonded to each other by Tl atoms.
A novel experimental and density functional theory study on palladium and nitrogen doped few layer graphene surface towards glucose adsorption and electrooxidation Caglar, Aykut; Duzenli, Derya; Önal, Işık; Tezsevin, Ilker; Sahin, Ozlem; Demir Kıvrak, Hilal (Elsevier BV, 2021-03-01) At present, few layer graphene (G) and nitrogen doped few layer graphene (N doped-G) are firstly coated on Cu foil via chemical vapor deposition (CVD) method and G and N doped-G coated Cu foil is transferred to the indium tin oxide (ITO) substrate surface to obtain electrodes. Pd metal is electrodeposited onto the N doped-G/ITO electrode (Pd-N doped-G/ITO). Pd-N doped-G/ITO electrode are characterized with advanced surface characterization methods such as Raman spectroscopy and SEM-EDX. Characterization res...
Crystal data, photoconductivity and carrier scattering mechanisms in CuIn5S8 single crystals Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2001-01-01) The X-ray diffraction has revealed that CuIn5S8 is a single phase crystal of cubic spinet structure. The value of the unit cell parameter for this crystal is 1.06736 nm. The crystal is assigned to the conventional space group Fd3m. The photocurrent is found to have the characteristic of monomolecular and bimolecular recombination at low and high illumination intensities, respectively. The electrical resistivity and Hall effect of CuIn5S8 crystals are measured in the temperature range of 50-400 K. The crysta...
Crystal data, electrical resistivity, and Hall mobility of n-type AgIn5S8 single crystals Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2001-01-01) The X-ray diffraction has revealed that AgIn5S8 is a single phase crystal of cubic spinel structure. The value of the unit cell parameter for this crystal is 1.08286 nm. The electrical resistivity and Hall effect of n-type AgIn5S8 crystals are measured in the temperature range of 50-400 K. A carrier effective mass of 0.20 m(0), an acceptor to donor concentration ratio of 0.8 and an acoustic phonons deformation potential of 20 eV are identified from the Hall effect measurement. The Hall mobility data art: an...
Solid state electrochromic device applications of N-(2-(thiophen-3-yl)methylcarbonyloxyethyl) maleimide Ak, Metin; DurtnuS, Asuman; Toppare, Levent Kamil (Elsevier BV, 2007-09-01) Homopolymer and copolymer of N-(2-(thiophen-3-yl)methylcarbonyloxyethyl) maleimide (NMThi) with thiophene [P(NMThi-co-Th)] were synthesized electrochemically in acetonitrile[borontrifluoride ethylether solvent mixture (1: 1, v/v). Spectroelectrochemical analysis of the resulting copolymer reflected electronic transitions at 488 and 718 nm revealing pi to pi* transition and polaron formation, respectively. Switching ability was evaluated by a kinetic study via measuring the transmittance (%T) at the maximum ...
