Ni-2 and Ni-13 clusters have been studied by means of DFT calculations performed at B3LYP level using three different basis sets. Equilibrium geometry calculations resulted in a binding energy of nickel dimer of 1.078 eV/atom for the basis set m6-31G*, showing good agreement with experimental data. Ni-13 nanocluster was found to have an equilibrium structure of icosahedral for all three basis sets in accordance with experimental findings. The intercept of the line obtained by drawing a correlation line of binding energies of Ni-2 dimer and Ni-13 nanocluster against n(-1/3), where n is the number of atoms in the cluster, gave a good estimation for bulk nickel binding energy at infinite n (4.57 eV/atom versus experimental value of 4.45 eV/atom) again using the basis set m6-31G*.

A density functional theory study of ethylene adsorption on Ni-10(111), Ni-13(100) and Ni-10(110) surface cluster models and Ni-13 nanocluster
Yilmazer, Nusret Duygu; Fellah, Mehmet Ferdi; Önal, Işık (2010-06-01)
Ethylene adsorption was studied by use of DFT/B3LYP with basis set 6-31G(d, p) in Gaussian' 03 software. It was found that ethylene has adsorbed molecularly on all clusters with pi adsorption mode. Relative energy values were calculated to be -50.86 kcal/mol, -20.48 kcal/mol, -32.44 kcal/mol and -39.27 kcal/mol for Ni-13 nanocluster, Ni-10(1 1 1), Ni-13(1 0 0) and Ni10(1 1 0) surface cluster models, respectively. Ethylene adsorption energy is inversely proportional to Ni coordination number when Ni-10(1 1 1...
First reference map for Phanerochaete chrysosporium proteome
Yıldırım, Volkan; Özcengiz, Gülay; Department of Biology (2006)
In this study, the soluble protein fraction of P. chrysosporium grown under standard conditions was analyzed by using 2D-PAGE approach and a 2-D reference map was constructed. 910 spots could be separated and detected on Coomassie-stained 2-D gels by the help of Delta2D image analysis software. 720 spots could be cut from the master gel and were subjected to MALDI-TOF MS analysis followed by MASCOT search. A total of 517 spots out of 720 were assigned to specific accession numbers from the P. chrysosporium ...
A density functional theory study on the structures and energetics of CdmTen clusters (m + n <= 6)
Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-06-01)
Density functional method has been used to study the structural features and energetics of CdmTen clusters (m + n <= 6). The results presented include the geometric structures, binding energies, Mulliken charges on atoms, vibrational frequencies and the corresponding non-zero infrared intensities, HOMO-LUMO energies and the frontier molecular orbital energy gaps, the most possible dissociation channels and their corresponding energies of the clusters.
A density functional theory study of propylene epoxidation on RuO2(110) surface
Atmaca, Deniz Onay; Duzenli, Derya; Ozbek, M. Olus; Önal, Işık (2016-11-01)
Propylene epoxidation is investigated on RuO2(110) and oxygen added RuO2-O-ot(110) surfaces by periodic DFT computational method. The desired product propylene oxide (PO) as well as the undesired products acetone (AC) or propionaldehyde (PA) form on both surfaces through either surface intermediate oxometallopropylene (OMMP) or direct oxygen insertion mechanisms. On RuO2(110) surface, nucleophilic lattice oxygen at bridge position (O-br) favors the stable surface intermediate mechanism where high energy req...
A simulated annealing approach to bicriteria scheduling problems on a single machine
Karasakal, Esra (2000-08-01)
In this paper, we apply a simulated annealing approach to two bicriteria scheduling problems on a single machine. The first problem is the strongly NP-hard problem of minimizing total flowtime and maximum earliness. The second one is the NP-hard problem of minimizing total flowtime and number of tardy jobs. We experiment on different neighbourhood structures as well as other parameters of the simulated annealing approach to improve its performance. Our computational experiments show that the developed appro...
