Detection of free radicals in gamma-irradiated seasnail hard tissues by electron paramagnetic resonance
Koseoglu, R; Koksal, F (Pergamon-Elsevier Science Ltd, 2003)Gamma-irradiated seasnail (from family of Helix lukortium) hard tissues (CaCO3) were investigated by electron paramagnetic resonance (EPR) at room temperature. The radicals produced by gamma-irradiation in seasnail were ... -
Disorder in KHCO3 as studied by EPR and DTA in Cu2+ doped and gamma-irradiated single crystals
Koksal, F; Karabulut, B; Demir, D; Icbudak, H; Koseoglu, R (Taylor & Francis Ltd, 2005)Kalicinite (KHCO3) single crystals were investigated by the electron paramagnetric resonance (EPR) technique in their Cu2+ doped and gamma- irradiated states. It is observed that the behavior of the spectrum is the same ... -
Electron paramagnetic resonance of natural and gamma-irradiated alunite and kaolin mineral powders
Koksal, F; Koseoglu, R; Saka, I; Basaran, E; Sener, F (Taylor & Francis Ltd, 2004)Natural alunite and kaolin minerals obtained from West Anatolia were investigated by electron paramagnetic resonance (EPR) in natural and gamma-irradiated states at room temperature and at 113 K. The paramagnetic centres ... -
Electron paramagnetic resonance of rhyolite and gamma-irradiated trona minerals
Koksal, E; Koseoglu, R; Basaran, EB (Verlag Z Naturforsch, 2003)Rhyolite from the "Yellow Stone of Nevsehir" and gamma-irradiated trona from the Ankara Mine have been investigated by electron paramagnetic resonance at ambient temperature and at 113 K. Rhyolite was examined by X-ray ... -
Electron paramagnetic resonance of some gamma-irradiated drugs
Koseoglu, R; Koseoglu, E; Koksal, F (Pergamon-Elsevier Science Ltd, 2003)Some drugs, used mainly in treatment of some neurological diseases and hypertension were exposed to gamma-irradiation, and the samples were investigated by electron paramagnetic resonance (EPR). The observed spectra were ... -
EPR of gamma irradiation induced radicals in NaHCO3, CsHCO3 and Na2CO3
Koksal, F; Koseoglu, R (Pergamon-Elsevier Science Ltd, 2000)In this study gamma irradiated NaHCO3, CsHCO3 and Na2CO3 were investigated at room temperature. The radicals induced by gamma irradiation in NaHCO3 were found to be (CO3-)-O-. (HCO3-)-O-. and (CO2-)-O-.; in CsHCO3 the ... -
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 ... -
EPR of some irradiated renal stones
Koseoglu, R; Koseoglu, E; Koksal, F; Basaran, E; Demirci, D (Pergamon-Elsevier Science Ltd, 2005)Some renal stones were investigated by electron paramagnetic resonance of their untreated, UV-photolyzed and gamma-irradiated states. Powder X-ray diffraction technique indicated that the renal stones were made mainly from ... -
