(In)compressibility and parameter identification in phase field models for capillary flows [PDF]
Theoretical and Applied Mechanics, 2017 Phase field (diffuse interface) models accommodate diffusive triple line motion with variable contact angle, thus allowing for the no-slip boundary condition without the stress singularities.

Photoelectrochemical Gas–Electrolyte–Solid Phase Boundary for Hydrogen Production From Water Vapor
Frontiers in Chemistry, 2018 Hydrogen production from humidity in the ambient air reduces the maintenance costs for sustainable solar-driven water splitting. We report a gas-diffusion porous photoelectrode consisting of tungsten trioxide (WO3) nanoparticles coated with a proton ...

Nickel–Zirconia Anode Degradation and Triple Phase Boundary Quantification from Microstructural Analysis [PDF]
Fuel Cells, 2009 AbstractMicrostructural evolution of anode supported solid oxide fuel cells (SOFC) during medium‐term stack testing has been characterised by scanning electron microscopy (SEM). Low acceleration voltage SEM imaging is used to separate the three anode phases (nickel, yttria‐stabilised zirconia and porosity).

Stability analysis of phase boundary motion by surface diffusion with triple junction [PDF]
Banach Center Publications, 2009 The linearized stability of stationary solutions for the surface diffusion flow with a triple junction is studied. We derive the second variation of the energy functional under the constraint that the enclosed areas are preserved and show a linearized stability criterion with the help of the H−1-gradient flow structure of the evolution problem and the ...

Melting Curve and Phase Relations of Fe‐Ni Alloys: Implications for the Earth's Core Composition
Geophysical Research Letters, 2020 Nickel is the second most abundant element in the Earth's core. However, the properties of Fe‐Ni alloys are still poorly constrained under planetary cores conditions, in particular concerning the effect of Ni on the melting curve of Fe. Here we show that
