Abstract Understanding mass transfer processes concomitant with electrochemical conversion for gas evolution reactions at the electrode-electrolyte interface plays a key role in advancing renewable energy storage and conversion. However, due to complicated diffusion behavior of dynamic catalytic interfaces, it is still great challenge accurately portray during electrocatalysis process. Here, we...

Liver cirrhosis is sometimes associated with very severe hypoxaemia, which is thought to be the result of intrapulmonary vascular dilatations (IPVDs). These vascular abnormalities, although close to the gas exchange units, are so dilated that diffusion of oxygen molecules to their centre is impaired, causing an increase in alveolar-arterial oxygen tension difference (P(A-a)O2). On the other han...

Reduction of MoO3 in propene and oxidation of MoO2 in oxygen are investigated by in situ X-ray diffraction (XRD) and Xray absorption spectroscopy (XAS). Temperature-programmed and isothermal experiments (573–773 K) are performed to elucidate the structural evolution of phases present during the reactions and, in addition, to reveal the solid-state kinetics of the processes involved. During the ...
