1, 2, 4-Triazole and 3-amino-1, 2, 4-triazole are useful starting materials for the synthesis of many 1, 2, 4-triazole-based explosives. Electronic properties and KamletJacobs detonation performances of PATO (3-picrylamino-1, 2, 4-triazole) (a relatively inexpensive, insensitive, and thermally stable explosive) and its 1, 3- and 1, 5- tautomers are investigated computationally using PM3, HF/6-31G(d, p), and B3LYP/6-31G(d, p) methods. The relationships between the thermodynamic and kinetic stabilities and the aromaticities are examined for all structures and their relative sensitivities are compared in terms of bond dissociation energies. The use of both PM3 and isodesmic methods in the calculation of heat of formation of PATO is discussed.

A DFT study on CO oxidation on Pd-4 and Rh-4 clusters and adsorbed Pd and Rh atoms on CeO2 and Ce(0.75)Z(r0.25)O(2) supports for TWC applications Gerceker, Duygu; Önal, Işık (2013-11-15) CO oxidation reaction mechanisms and energetics are examined on adsorbed Pd-4 and Rh-4 clusters and adsorbed Pd and Rh atoms on CeO2 and Ce0.75Zr0.25 O-2 support structures using DFT methods. Activation barriers and TS structures are computed with CI-NEB method. On cluster adsorbed systems, Zr affects CO binding position and O-2 adsorption mode. Energetically, formation of two CO2 molecules without barrier and surface regeneration is possible only on Pd-4-CeO2 surface. With metal atom substituted surfaces, ...
A comparative experimental and density functional study of glucose adsorption and electrooxidation on the Au-graphene and Pt-graphene electrodes Caglar, Aykut; Duzenli, Derya; Önal, Işık; Tersevin, Ilker; Sahin, Ozlem; Demir Kıvrak, Hilal (2020-01-01) At present, the graphene is covered on Cu foil with the 5 sccm hexane (C6H14) flow rate, 50 sccm hydrogen (H-2) flow rate, and 20 min deposition time parameters by the CVD method. The graphene on the Cu foil is then covered onto few-layer ITO electrode. Furthermore, the Pt and Au metals are electrodeposited on graphene/ITO electrode with electrochemical method. These electrodes are characterized by Raman spectroscopy and Scanning Electron Microscopy-Energy Dispersive X-Ray analysis (SEM-EDX). The graphene s...
A new method for processing of monazite and examination of the products by X-ray analysis Kizilyalli, Meral; Welch, Alastair J. (Elsevier BV, 1987-1) Sintering reactions of lanthanide orthophosphates with Na2CO3 gave the expected products (Na3PO4 and Ln2O3) with stoichiometric amounts of Na2CO3. When less than the theoretical amounts of Na2CO3 were used, two intermediate products eventually characterized by X-ray diffraction as Na3Ln(PO4)2 and Ln3PO7 were detected. Application of the sintering method to naturally occurring phosphates, particularly the mineral monazite, proved to be very successful. By using the optimum amount of Na2CO3 to form Na3Ln(PO4)...
Use of general purpose adsorption isotherms for heavy metal clay mineral interactions Altin, O; Özbelge, Hilmi Önder; Dogu, T (Elsevier BV, 1998-02-01) General purpose adsorption isotherm equations were fitted to the sorption data of lead and cadmium on both unmodified and Ca-saturated kaolinite and montmorillonite. Langmuir-Freundlich, Redlich-Petersen, Toth, Dubinin-Radushkevich, competitive Langmuir, and some modified forms of these isotherms were fitted to experimental data, and their goodnesses of fit are compared. The adjustable parameters of the Langmuir-and Freundlich-based isotherms were estimated by nonlinear least-squares analysis. The applicati...
A theoretical study on the strong codimer of C-60 and Si-60, C58Si58 Türker, Burhan Lemi (2001-07-09) The strong codimer Of C-60 and Si-60 that is C58Si58 is considered for AM1 type semiempirical molecular orbital treatment at the, restricted Hartree-Fock level. The results reveal that C58Si58 structure should be highly endothermic but a stable molecule. The structure is expected to have some nonlinear properties.
