The report presents results of development of an accurate, physics-based model of vibrational androtational energy transfer in three-dimensional collisions of rotating diatomic molecules, applicable over awide range of collision energies and vibrational / rotational quantum numbers, and results of detailedkinetic modeling studies of state-to-state molecular energy transfer processes...

The effect of molecular vibrations on electronic transport is investigated with the smallest fullerene C20 bridge, utilizing the Keldysh nonequilibrium Green's function techniques combined with the tight-binding molecular-dynamics method. Large discontinuous steps appear in the differential conductance when the applied bias voltage matches particular vibrational energies. The magnitude of the s...

original article   noise and vibration are the common problems in industrialized countries which can affect individual's job performance. the present study aimed to investigate the combination of the whole body vibration and the noise and their effects on the students' mental performance in the laboratory setting. twenty male students of tehran university of medical sciences, tehran, iran were ...
