Lubrication of dislocation glide in forsterite by Mg vacancies: insights from Peierls-Nabarro modeling

, 2018
Dislocation glide is an important contributor to the rheology of olivine under conditions of high stress and low to moderate temperature, such as occur in mantle wedges. Interactions between point defects and dislocation core may alter the Peierls stress,

Interfacial Failure and Self‐Healing in Solid‐State Batteries

Advanced Materials, Volume 38, Issue 58, 16 October 2026.
Dynamic interfacial self‐healing offers an adaptive route to mitigate coupled mechanical, chemical, and electrochemical degradation in solid‐state batteries. This review connects evolving interfacial failure mechanisms with physical‐flow, chemical‐restoration, stimuli‐responsive, and electric‐field‐assisted repair strategies, highlighting targeted self‐

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System

Advanced Science, Volume 13, Issue 55, 5 October 2026.
An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Stabilized Cubic GeTe With Matched Grain‐Boundary Networks and Band Convergence for High‐Performance Dual‐Mode Thermoelectric Devices

Advanced Science, Volume 13, Issue 57, 14 October 2026.
I‐doping stabilizes the cubic phase of GeTe and generates “electron‐transparent, phonon‐blocking” grain boundary networks while inducing valence‐band convergence. This synergistic structural‐electronic design enables effective electron‐phonon decoupling, achieving an exceptional average zTave of ∼1.62, a peak zT of ∼2.2, and enhanced mechanical ...

Modeling Catheter‐Associated Bladder Mucosal Adhesion and Microtrauma Using a Human Urothelial Microtissue Model

Advanced NanoBiomed Research, Volume 6, Issue 10, October 2026.
Intermittent catheter use can damage the urinary tract and predispose to infection. We deployed a complex human urothelial model to investigate. Catheter contact induced compressive and shear stress causing umbrella cell disruption, reduced barrier function, inflammation and increased cell adhesion to the catheter surface.

Transcatheter Tricuspid Valve Replacement for Residual Tricuspid Regurgitation After TEER

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1380-1385, October 1, 2026.
ABSTRACT Background Residual or recurrent tricuspid regurgitation (TR) after prior transcatheter tricuspid edge‐to‐edge (T‐TEER) repair occurs in about 12% of patients within 1 year. Since surgical tricuspid valve repair or replacement is of high risk, treatment options remain scarce.

Strain‐Dependent Evolution of Fatigue and Oxidation Damage in a Nickel‐Based Single‐Crystal Superalloy: The Dominant Mechanism Under Low‐Cycle and Thermomechanical Fatigue

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Systematic studies on the fatigue deformation and damage mechanisms of nickel‐based single‐crystal superalloys (Ni‐SXs) under combined thermal and mechanical conditions remain limited, particularly regarding the influence of strain amplitude on the relative contributions of fatigue and oxidation damage.
