In the present work bulk-diffusion problem of electrochemically inserted solute particles, e.g. hydrogen, in planar or cylindrical electrodes is treated with a boundary condition, which considers simultaneously both sinusoidal modulation particle flux as well reaction rate insertion into electrode. By solving this diffusion–reaction model superimposed concentration inside sample obtained. For application to electrochemical charging, related that follows from Butler-Volmer equation. The phase...
The effect of high-pressure torsion (HPT) on the corrosion behavior a bioresorbable MgCaZn alloy (ZX00) is studied by positron annihilation.
Nanoporous gold is modified with self-assembled monolayers (SAMs) of different length. The point zero charge and the protonation/deprotonation reaction are investigated revealing precise control for long-chain SAMs.
The positronium chemistry of a Fe2+/3+ solution is studied under full electrochemical control. For this novel approach to electrochemistry, suitable cell setup used, which allows simultaneously both measurements and positron annihilation spectroscopy. the redox couple, serves as an ideally suited atomic probe owing rather different Fe2+ (spin conversion) Fe3+ (total inhibition oxidation). This enabled precise in situ monitoring oxidation reduction by means lifetime upon slow cycling...
The increasing structural complexity in modern material science is often associated with grain sizes the
Switching of positronium triplet quenching could successfully be demonstrated by electrochemical means in an aqueous K3[Fe(CN)6] electrolyte. For this purpose a suitable cell was designed to combine positron annihilation with measurements. Highly reversible substantial variations the mean lifetime τm observed upon switching between oxidation states Fe(CN)63- and Fe(CN)64-, arising from Fe(CN)63-. Dynamic situ measurements dependence potential exhibit hysteresis like behavior which perfectly...
