The Li(+) ion diffusion coefficients (DLi+) in V2O5 (2.12 × 10(-12) cm(2) s(-1)) and in the intermediate α-, ε-, and δ-LixV2O5 phases (1.6 × 10(-14), 8.0 × 10(-15), and 8.5 × 10(-15) cm(2) s(-1), respectively), reversibly formed during charging/discharging processes of the crystalline-V2O5 and PEDOT (poly-3,4-ethylenedioxythiophene) composite-film(More)
a r t i c l e i n f o a b s t r a c t Keywords: Mid-Atlantic Ridge slow-spreading ridge autonomous underwater vehicle sidescan sonar sea-floor spreading volcanism The upper oceanic crust is produced by magmatism at mid-ocean ridges, a process thought to be characterized by cyclic bouts of intense magmatic activity, separated by periods when faulting(More)
The electrochemical activities of PbO(2) thin-film electrodes were systematically studied with an oxygen-transfer reaction, i.e., the oxidation of thiourea. Five different types of PbO(2) film electrodes were prepared using various methods to investigate the influence of the interfacial oxide layer formed between the Ti substrate and the PbO(2) layer(More)
An instrumental setup has been configured for a simultaneous real time recording of electrochemical, spectroelectrochemical, and mass data on an electrode from a single measurement for studies of complex electrochemical reaction mechanisms. This was achieved by combining a few pieces of equipment: a potentiostat/galvanostat for electrochemical measurements,(More)
