To investigate the electromagnetic interaction of molecules inside the nanotubes, first, the structure of nanotubes B16N16 was optimized with hybrid density functional theory (B3LYP) using the EPR-II basis set, then Cu, Cu+, Cu++ were located in nanotube and we studied the total energy, band gap energy, electrical potential, changes of band gap energy in terms of total energy and dipole moment ...
in this paper, using monte carlo fortran code, we have obtained the binding energies for three different systems of diquark–antidiquark in distances from 0.01 to 15 nm. in [0.1 - 15] nm interval, we made use of coulomb potential because in this interval, strong interaction is negligible. we have compared the binding energies of the systems with one another. the results of these comparisons were...
background: fragile histidine triad protein (fhit), as a known tumor suppressor protein, has been proposed to play crucial role in inhibiting p53 degradation by mdm2. studies have confirmed fhit interaction with p53 or mdm2, although functional interacting domains of fhit with mdm2 and/or p53 are not completely defined. thus, through determining the significant structural interacting domains of...
the interaction of dopamine and cysteine for formation of 5-s-cysteinyldopamine are investigated at thehartree-fock level theory. the structural and vibrational properties of 5-s-cysteinyldopamine are studiedat level of hf/6-31g*.interaction energy ( ae) is calculated -771.6923 kcal/mol rotational energy andthermodynamic parameters around two bond have been determined using hf/3-21g. changes of...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
The investigation of the anticancer drugs will be important because of the proliferation ofcancer. We want to take steps to improve public health. The combination of two carbon nanotubes (singlewall nanotube and multi-wall nanotube) and Sup90-Dota (an anticancer drug) was investigated basedon Molecular Mechanic and Semi-Empirical methods. Our goal is to investigate the transfe...
stability of the π-π stacking interactions in the ben||n-substituted-coronene complexes was studied using the computational quantum chemistry methods (where ben is benzene and || denotes π-π stacking interaction, and n-substituted-coronene is coronene molecule which substituted with different number of n atoms). the results reveal simultaneous effects of structure and number of heteroatom on th...
background: gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. objective: the aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles gnps with x-rays as a function of nanoparticle size and beam energy and ...
to get a mole of a gas, it is necessary to calculate the intermolecular interaction. theseintermolecular interactions can be depicted by drawing the potential energy of a pair molecule inrelation to the distance. the intermolecular potential energy surface in the mixtures of ch4-h2cogases from ab initio calculations has been explored. in ab initio calculations the basis setsuperposition error (...
