Electrochemical Role of Li‐Ligands at the Triple‐Phase Boundary in Li‐O₂ Batteries

Small
AbstractThe increasing global energy demand drives interest in high‐energy‐density alternatives to lithium‐ion batteries, with Li‐O2 batteries emerging as promising candidates due to their exceptionally high theoretical energy density. However, the gap between the theoretical and practical energy densities remains significant, primarily due to the ...

Liquid|Liquid|Electrode Triple-Phase Boundary Photovoltammetry of Pentoxyresorufin in 4-(3-Phenylpropyl)pyridine

Langmuir, 2011
Voltammetric responses of pentoxyresorufin in 4-(3-phenylpropyl)-pyridine (PPP) microdroplets immersed in aqueous electrolyte are investigated in the absence and in the presence of light. The reduction of pentoxyresorufin to leuco-pentoxyresorufin in the dark is shown to occur in a two-electron, two-proton process sensitive to the aqueous pH and the ...

Geometrical triple phase boundary length measurement using focused ion beam tomography

The Canadian Journal of Chemical Engineering, 2011
AbstractIn multi‐component materials, triple phase boundary (TPB) is the location where reactions occur. A typical example is the TPB encountered in solid oxide fuel cells at the cathode–electrolyte interface. We proposed a tomographic approach that was developed based on serial sectioning using a focused dual ion beam (FIB) system.

Existence of a positive solution to a nonlinear system of PDEs in a domain with a triple-phase boundary

2013
We consider a system of nonlinear PDEs describing the reaction-diffusion dynamics near a triple-phase boundary in the catalyst layer of hydrogen fuel cells. The system involves bulk diffusion and surface reaction-diffusion processes and is an approximation of a model with a thin layer.
