Anti-sintering ZrO2-modified Ni/alpha-Al2O3 catalyst for CO methanation

open access: yes, 2016
To obviously reduce the sintering behavior of Ni particles in Ni/alpha-Al2O3 catalysts during CO methanation reaction, ZrO2 was deposited onto the Ni/a-Al2O3 catalyst surface by a modified impregnation method.

Operando X‐Ray Diffraction Analysis of Microscopic Structural Response in 33‐ and 31‐Mode Geometries Under an Applied Electric Field in (100)/(001)‐Oriented Epitaxial Tetragonal Pb(Zr, Ti)O3 Films Grown on (100) Si Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
Operando synchrotron x‐ray diffraction reveals the microscopic structural response of multidomain epitaxial tetragonal Pb(Zr,Ti)O3 thin films during both 33‐ and 31‐mode actuation. Ferroelastic domain switching is directly correlated with out‐of‐plane and in‐plane lattice deformation, while time‐resolved measurements demonstrate distinct different ...

SiO2-stabilized Ni/t-ZrO2 catalysts with ordered mesopores: one-pot synthesis and their superior catalytic performance in CO methanation

open access: yes, 2016
How to improve both the anti-sintering ability and the anti-coking ability of catalysts is still a big challenge in CO methanation for production of synthetic natural gas. To address the issue, we designed and synthesized a series of multicomponent Ni-Zr

Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

open access: yesAdvanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

Decoupling Thermodynamic and Kinetic Moisture Instability Reveals a Critical Humidity Threshold for Sodium Thiophosphate Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
A quantitative exposure‐heat treatment framework identifies a critical humidity threshold (15%RH) and heat treatment temperature (80°C) that governs the recoverability of air‐exposed Na3PS4, revealing the decoupled thermodynamic and kinetic contributions to its moisture stability.

Chemical and nanoindentation study of diffusion during sintering of 12Ce-ZrO2/3Y-ZrO2 powder layers

open access: yes, 2018
Tetragonal zirconia polycrystals doped with 3% mol of yttria (3Y-ZrO2) exhibit excellent mechanical properties and biocompatibility. However, under humid environments, their surface structural integrity is degraded by aging (low temperature degradation).

Electrolyte‐free cathode design for solid‐state batteries demonstrated with bifunctional Li2VCl4

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
The “electrolyte‐free” cathode design is demonstrated by utilizing the ion‐conducting active material Li2VCl4. This design is exclusively viable within all‐solid‐state battery configurations, where both active materials and electrolytes exist in the solid state.
