Diaminopyrimidinium squarate 1.394-hydrate
Koroglu, A (Int Union Crystallography, 2006)In the title compound, 2C(4)H(5)N(3)(+)center dot C4O4 (2-)center dot 1.394H(2)O, both the squarate and the aminopyrimidinium molecules lie on a crystallographic mirror plane and the water molecules are located between the ... -
Electronic energy loss of the partially stripped boron-like and carbon-like fast ions
Gumus, H; Ozalp, C; Koroglu, A (Polish Acad Sciences Inst Physics, 2003)An analytical formula of the electronic stopping power expression in this study was derived for swift boron-like and carbon-like ions by using first-order perturbation theory and frozen-charge-state model. The Hartree-Fock-Slater ... -
EPR of gamma-irradiation-induced free radicals in chicken, duck, and quail egg shells
Koksal, F; Demir, D; Koseoglu, R; Birey, M; Koroglu, A (Springer Wien, 2005)Chicken, duck, and quail egg shells were gamma-irradiated and investigated by electron paramagnetic resonance (EPR) at ambient temperature and at 113 K. The EPR-active species after gamma-irradiation were attributed to the ... -
ESR of gamma irradiated (NH4)(2)C2O4 center dot H2O and K2C2O4 center dot H2O single crystals
Tezel, O; Koroglu, A; Gencten, A; Celik, F (Natl Inst Science Communication, 1999)The gamma irradiated samples of both vacuumed powders and single crystals of (NH4)(2)C2O4.H2O and K2C2O4.H2O have been investigated by ESR method. The spectra for both these crystals were attributed to RCHOH and CO2- ... -
ESR of gamma irradiated C2H2O4.2H(2)O single crystal
Tezel, O; Koroglu, A; Tapramaz, R (Marcel Dekker Inc, 2000)The gamma-irradiated samples of vacuumed powder and single crystal of C2H2O4.2H(2)O have been investigated by ESR method. The spectra of these single crystal and unvacuumed powder are attributed to R C HOH radical, but the ... -
Oxygen/nitrogen ordering in lanthanum new phase (La3Si8N11O4)
Koroglu, A; Thompson, DP; Apperley, DC; Harris, RK (Academic Press Inc Elsevier Science, 2004)High-resolution O-17 NMR spectra have been collected for crystalline samples of lanthanum new phase, La3Si8N11O4. In conjunction with previously published Si-29 and N-15 spectra obtained for this phase, and in the light ... -
Proton sharing in bis(4-carbamoyl-pyridinium) squarate
Koroglu, A; Bulut, A; Ucar, I; Nichol, GS; Harrington, RW; Clegg, W (Int Union Crystallography, 2005)Reaction in aqueous solution of nickel(II) squarate with isonicotinamide yielded well formed yellow crystals of the title compound, 2C(6)H(6)N(2)O(+)center dot C4O42-, as a side product. The squarate dianion is bisected ... -
A second monoclinic polymorph of 2,9-dimethyl-1,10-phenanthroline dihydrate
Koroglu, A; Bulut, A; Ucar, I; Nichol, GS; Harrington, RW; Clegg, W (Int Union Crystallography, 2005)A second monoclinic polymorph of the title compound, neocuproine dihydrate, C14H12N2 center dot 2H(2)O, is reported. Unlike the first polymorph [Baggio, Baggio & Mombru (1998). Acta Cryst. C54, 1900-1902], in which the ... -
Silicon/aluminum and oxygen/nitrogen ordering in lanthanum U-phase (La3Si3Al3O12N2)
Koroglu, A; Thompson, DP; Apperley, DC; Harris, RK (Academic Press Inc Elsevier Science, 2004)High-resolution Si-29, Al-27, N-15, and O-17 MAS NMR spectra have been obtained for both glass and crystalline samples of lanthanum U-phase, La3Si3Al3O12N2,. Previous X-ray single-crystal studies have shown that this phase ... -
Stopping power calculations for partially stripped projectiles in high energy region
Tufan, MC; Koroglu, A; Gumus, H (Polish Acad Sciences Inst Physics, 2005)The electronic stopping cross-section is calculated in the spirit of the Bethe theory. Interaction potential between projectile and target is regarded to have a Coulombic character and we have modified it to take into ... -
A theoretical application of SEMUT NMR spectroscopy to deuterated compounds
Gencten, A; Tezel, O; Koroglu, A (Springer Wien, 2001)The product operator formalism is widely used for analytical description of multiple-pulse nuclear magnetic resonance (NMR) experiments for weakly coupled spin systems. C-13 subspectral editing with a multiple quantum trap ...
