An explicit approximate expression for half-wave potentials of irreversible steady-state current-voltage curves at a microdisk electrode was derived from the diffusion equation and the Butler-Volmer equation on the basis of the previous analytical method (J. E. C., 235 (1987) 87). The plot of the half-wave potential, E1/2, against ln(1-exp(-(E1/2E))F/RT)] showed a linear relation with the slope...

A time-dependent wave packet method has been developed to study atom–triatom ABC1D→AB1CD reactions in full six dimensions ~6D!. The approach employs a body-fixed coupled angular momentum basis for three angular coordinates, and three 1D bases for three radial coordinates. It permits the calculation of diatom AB vibrational state resolved total reaction probability for an initial rovibrational s...

A versatile precision rectifier based on a current conveyor and current mirrors is presented. The proposed circuit performs positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectification into a single circuit. The current-mode technique has been employed to provide the high-precision capability of the circuit. The circuit configuration is very suitable for inte...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

A time-dependent wave packet method has been employed to calculate the state-to-state reaction probability for the H1H2O~0,0,0!→H2~v1 , j1!1OH~v2 , j2! reaction for J50 and initial nonrotating H2O on the modified Schatz–Elgersman potential energy surface in full six dimensions ~6D!. Starting from a wave packet for an atom–triatom asymptotic state in atom–triatom Jacobi coordinates, we transfer ...
