the kinetics and mechanism of the reaction of 5-nitro-1h-benzo[d] imidazole to produce 6-nitro-1h-benzo[d] imidazole was studied by employing hybrid meta-density functional theory. mpwblk/6-31+g** level calculations were carried out to obtain energies and optimize the geometries of all stationary points along the pes, and determine the harmonic vibrational frequencies. two transition states (ts...
Base on the non-relativistic Faddeev AGS method, three-body calculations of the coupled and quasi-bound KKN-πKΣ system are performed in the momentum space. Different phenomenological models of KN-πΣ potentials with one and two-pole structures of KN-πΣ resonance are used to study the dependence of double-kaonic system binding energy on the coupled KN-πΣ interaction. Also, the effect of the KK r...
In this paper, electron acceleration in the field of laser pulse is investigated. To limit the interaction region for electron pulse, which is required for acceleration, a new method is presented based on the injection of electron on temporal peak of the laser pulse. In this method, the electron is provided by a plasma source and is steered inside the laser field by utilizing the magnetic field...
The flux-pinning mechanism and activation energy of 10 wt % malic acid-doped MgB2 were investigated by measuring of the critical current density and resistivity as a function of magnetic field and temperature. A crossover field, Bsb, was observed from the single vortex to the small vortex bundle pinning regime. For the sintered sample, the temperature dependence of Bsb(T) at low temperature i...
