An infrared spectroscopic study on a divalent metal salt of p-aminobenzoic acid [ABA(Mg)] tetracyanonickelate

Atalay, Yusuf; Okur, İbrahim; Demir, Zafer (MARCEL DEKKER INC, 2002)

Infrared spectra of MLNi (CN)(4) [M=Mn, Fe, Co, Ni, Zn or Cd and L= Divalent metal of p-Aminobenzoic Acid or ABA (Mg)] are reported. Their structure consists of polymeric layers of [M-Ni(CN)(4)](a) with the divalent metal ...
(e, 2e) experiments on (2s(2))S-1, (2p(2))D-1 and (2s2p)P-1 autoionizing levels of helium in the direction of the binary lobe

Doğan, Metin; Okur, İbrahim (IOP PUBLISHING LTD, 2010)

The (e, 2e) triple differential cross sections are measured for the electron-impact excitation of the (2s(2))S-1, (2p(2))D-1 and (2s2p)P-1 autoionizing transitions in helium. The experiments were performed under coplanar ...
Electron-impact excitation of the (2p(2)) D-1 and (2s2p) P-1(o) autoionizing states of helium

Doğan, Metin; Okur, İbrahim (AMER PHYSICAL SOC, 2011)

An experimental study of the excitation of the (2p(2)) D-1 and (2s2p) P-1(o) autoionizing states of helium by 250-eV electron impact is presented. The ejected-electron angular distributions and energy spectra are measured ...
Laser annealing and in situ absorption measurement of float glass implanted with Ag ions

Okur, İbrahim (ELSEVIER SCIENCE BV, 2004)

In this paper in situ pulsed laser annealing and absorption measurements results of Ag-implanted float glass are reported. A Nd:YAG laser harmonic at 266 nm was used to anneal the target area by coupling energy to the glass ...
Molecular structure and vibrational spectra of melamine diborate by density functional theory and ab initio Hartree-Fock calculations

Atalay, Yusuf; Avcı, Davut; Başoğlu, Adil; Okur, İbrahim (ELSEVIER SCIENCE BV, 2005)

The molecular geometry-and vibrational frequencies of melamine diborate in the ground state have been calculated using the Hartree-Fock and density functional methods (B3LYP) with 6-31G(d) basis set. The optimized geometric ...
OLPT CONDUCTIVITY IN WOLLASTONITE INLAID NR/SBR TYPE ELASTOMER BASED MATERIAL

Şentürk, Erdoğan; Demirer, Ahmet; Okur, İbrahim (UNIV CHEMISTRY & TECHNOLOGY, PRAGUE, 2012)

The electrical properties of wollastonite inlaid NR/SBR type elastomer based material have been evaluated. Electrical properties of the samples were measured in the temperature range of 303 to 453 K and the frequency range ...
On the one-parameter Lorentzian spherical motions and Euler-Savary formula

Tosun, Murat; Güngör, Mehmet Ali; Okur, İbrahim (ASME, 2007)

In this paper we have introduced one-parameter Lorentzian spherical motion. In addition to that, we have given the relations between the absolute, relative, and sliding velocities of these motions. Furthermore, the relations ...
Optical and structural effects of Dy doping in ZnO thin films on quartz glasses using the spin coating method

Ozlem Ertek Guldali; Okur, İbrahim (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2016)

In the present paper, the optical and structural parameters of pure and Dy doped zinc oxide thin films on quartz glass substrate using the dopant of Dy in various doping molar concentrations (0.2 and 0.5 M) with different ...
Producing CuO and ZnO composite thin films using the spin coating method on microscope glasses

Okur, İbrahim (ELSEVIER, 2013)

In this work, we have presented a new route to produce pure ZnO and composite ZnO-CuO thin films. In the process we have started with pure ZnO thin films and ended up with CuO by doping Cu in various percentages, ranging ...
The Effects of Thermal Annealing on ZnO Thin Films Produced by Spin-Coating Method on Quartz Substrates

Ozlem Ertek; Okur, İbrahim (SPRINGER/PLENUM PUBLISHERS, 2015)

In this work, zinc oxide (ZnO) thin films on quartz substrates were fabricated using the spin-coating method. Thermal annealings from to have been performed in increments and for two annealing durations (0.5 h and 8 h). ...
The Structural Properties of ZnO Thin Films Produced in Different Molarities by Spin Coating Method
