This work describes the fabrication, characterization and evaluation of thin gas diffusion electrodes (GDEs) that are capable of electrocatalyzing the reaction of dissolved gases operating at high diffusion limiting current ...

The coverage dependence of the one-dimensional collective diffusion coefficient is analyzed by using the gradient expansion of the local density. The transition probabilities are written as an expansion of the probabilities ...

This study compares the goodness of fit of 10 empirical models used to predict gas diffusivity (DpD0-1) with experimental data obtained from Chilean soil samples from different soil management practices. Nine sites under ...

We study self-diffusion of particles in gas-driven granular layers by high-speed fluorescent video microscopy. We show that periodic flow modulation results in an enhancement of the particle's diffusion. The diffusion ...

A flow system for sulphite determination in wines and fruit juice samples has been developed exploiting H2S generation and gas diffusion separation. The composed sandwich gas diffusion cell was coupled in the flow manifold ...

A flow-injection system is proposed for the spectrophotometric determination of sulphite in white wines. The method involves analyte conversion to SO2, gas diffusion through a Teflon® semi-permeable membrane, collection ...
