Effect of Synthesis Method of Nickel–Samarium-Doped Ceria Anode on Distribution of Triple-Phase Boundary and Electrochemical Performance

open access: yesCrystals, 2021
Two-dimensional (2D) electron back scattered diffraction (EBSD) is a powerful tool for microstructural characterization of crystalline materials. EBSD enables visualization and quantification of the effect of synthesis methods on the microstructure of ...

New phase-field model for polycrystalline systems with anisotropic grain boundary properties

open access: yesMaterials & Design, 2022
In this paper, a new methodology is presented to inlude anisotropic grain boundary properties in a phase-field model. The new approach is thermodynamically consistent and gives accurate control of the inclination and misorientation of grain boundary ...

(In)compressibility and parameter identification in phase field models for capillary flows [PDF]

open access: yesTheoretical 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.

Correlation between grain boundary character distribution and δ-phase precipitation in nickel-based superalloy 718

open access: yesJournal of Materials Research and Technology, 2020
The nickel-based superalloy 718 after processing through three thermomechanical routes, i.e., forged, hot rolled, and cold rolled, was investigated considering its δ-phase (Ni3Nb–DOa) intergranular precipitation.

Photoelectrochemical Gas–Electrolyte–Solid Phase Boundary for Hydrogen Production From Water Vapor

open access: yesFrontiers 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 ...

Unified Boundary Control With Phase Shift Compensation for Dual Bridge Series Resonant DC-DC Converter

open access: yesIEEE Access, 2020
In this paper, the triple-phase-shift (TPS) control with certain unified boundary conditions is applied to a dual-bridge series resonant converter (DBSRC) for applications needing bidirectional energy flow ability. The control strategy is unified for the

Melting Curve and Phase Relations of Fe‐Ni Alloys: Implications for the Earth's Core Composition

open access: yesGeophysical 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
