An explosive material, ethylenedinitramine (EDNA), its mono and di aci forms, as well as its monovalent cation and anion forms have been considered for 6-31G (UHF) type ab initio quantum chemical treatment in order to investigate the stability of EDNA in the neutral form and when charges develop on it exposed to electrical fields during the storage, handling or explosion process. The calculations indicate stable species. The aci forms are less stable than EDNA itself and the anion form is more stable than the neutral and cation forms. Although, the charge development is accompanied by some elongation or contraction of bonds and deviation of bond angles also as compared to the neutral state, no bond rapture occurs.

Quantum chemical treatment of cyanogen azide and its univalent and divalent ionic forms Türker, Burhan Lemi; Atalar, Taner (Elsevier BV, 2008-05-30) An explosive material, cyanogen azide (CN4) and its univalent and divalent anionic and cationic forms have been studied quantum chemically by using different theoretical approaches. In this study, the structures considered have been screened for their relative stabilities. Also, they have been investigated whether the charged forms play a role in the usual explosion process or any electrical charging during storage cause explosion. Various quantum chemical properties are obtained and discussed. It has been ...
A theoretical study on vomitoxin and its tautomers Türker, Burhan Lemi; Guemues, Selcuk (Elsevier BV, 2009-04-15) In the present work, the structural and electronic properties of vomitoxin (deoxynivalenol, a mycotoxin) and all of its possible tautomers have been investigated by the application of B3LYP/6-31 G(d,p) type quantum chemical calculations. According to the results of the calculations, tautomer V-4 has been found to be the most stable one among all the structures both in the gas and aqueous phases. The calculations also indicated that, vomitoxin and V-2 possess the deepest and the highest lying HOMO levels, re...
Density functional theory calculations for [C2H4N2O6]((n)) (n=0,+1,-1) Turker, Lemi; Erkoç, Şakir (Elsevier BV, 2006-08-21) The structural and electronic properties of neutral and mono ionic structures of isolated ethylene glycol dinitrate (EGDN) [C2H4N2O6]((n)) (n = 0, +1, -1) have been investigated by performing density functional theory calculations at B3LYP level. The optimum geometry, vibrational frequencies, electronic structure and some thermo dynamical values of the structures considered have been obtained in their ground states. The calculations reveal that as the charge develops the bond lengths and angles change. In t...
Catalytic combustion of ethyl acetate GÜRMEN ÖZÇELİK, TUĞBA; Atalay, Sueheyda; Alpay, Erden (Elsevier BV, 2007-01-01) The catalytic combustion of ethyl acetate over prepared metal oxide catalysts was investigated. CeO, Co2O3, Mn2O3, Cr2O3, and CeO-Co2O3 catalysts were prepared on monolith supports and they were tested. Before conducting the catalyst experiments, we searched for the homogeneous gas phase combustion reaction of ethylacetate. According to the homogeneous phase experimental results, 45% of ethylacetate was converted at the maximum reactor temperature tested (350 degrees C). All the prepared catalysts were test...
Evaluation of PCB dechlorination pathways in anaerobic sediment microcosms using an anaerobic dechlorination model Demirtepe, Hale; Kjellerup, Birthe; Sowers, Kevin R.; İmamoğlu, İpek (Elsevier BV, 2015-10-15) A detailed quantitative analysis of anaerobic dechlorination (AD) pathways of polychlorinated biphenyls (PCBs) in sediment microcosms was performed by applying an anaerobic dechlorination model (ADM). The purpose of ADM is to systematically analyze changes in a contaminant profile that result from microbial reductive dechlorination according to empirically determined dechlorination pathways. In contrast to prior studies that utilized modeling tools to predict dechlorination pathways, ADM also provides quant...
