Extreme high lattice-misfit superalloys with regular cubic L12 particles and excellent creep resistance

In novel Co and CoNi based superalloys, the creep resistance is limited at high temperatures due to low lattice misfit and solvus temperature. In this study, we combined the advantages of Co-Ti (high lattice misfit and solvus temperature) and Co-Al based

A phase field crystal model simulation of morphology evolution and misfit dislocation generation in nanoheteroepitaxy

, 2017
A phase field crystal (PFC) model is employed to study morphology evolution of nanoheteroepitaxy and misfit dislocation generation when applied with enhanced supercooling, lattice mismatch and substrate vicinal angle conditions. Misfit strain that rises

Critical thickness for the formation of misfit dislocations originating from prismatic slip in semipolar and nonpolar III-nitride heterostructures

APL Materials, 2016
We calculate the critical thickness for misfit dislocation (MD) formation in lattice mismatched semipolar and nonpolar III-nitride wurtzite semiconductor layers for the case of MDs originated from prismatic slip (PSMDs). It has been shown that there is a

A Cation‐Specific Strain Design Principle for Surface Segregation in Perovskite Oxides

EcoEnergy, EarlyView.
La‐ and Sr‐based perovskites exhibit opposite strain‐dependent cation stability due to their distinct intrinsic stability optima. Strain engineering toward these cation‐specific optima suppresses surface segregation, providing a unified design principle for durable perovskite oxide electrodes.

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.
