A semi-analytic method for crack kinking analysis at isotropic bi-material interfaces
, 2012 Interface delamination is a key failure mechanism in numerous applications. Microscopic analysis illustrates that macroscopic delamination may contain both adhesive and cohesive cracking.

Angewandte Chemie International Edition, EarlyView.By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Quasistatic crack growth based on viscous approximation: a model with branching and kinking [PDF]
, 2017 Employing the technique of vanishing viscosity and time rescaling, we show the existence of quasistatic evolutions of cracks in brittle materials in the setting of antiplane shear.

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries
Batteries &Supercaps, Volume 8, Issue 3, March 2025.Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Evaluation of the intrinsic crack growth rates of weld joints [PDF]
, 2011 A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

Interventional Mitral Valve Edge‐to‐Edge Repair in Patients Above 85 Years of Age
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Mitral valve transcatheter‐edge‐to‐edge repair (M‐TEER) is routinely performed in patients with severe mitral regurgitation (MR) at high operative risk, frequently including elderly patients. Patients ≥ 85 years, however, are frequently excluded in clinical studies.

Fully Reversible Regulation of 8‐17 DNAzyme Activity Using Nucleoside‐Based Diarylethenes
Chemistry – A European Journal, EarlyView.The site‐specific incorporation of nucleosidic diarylethenes into the 8–17 deoxyribozyme (DNAzyme) identified position 2.1 as optimal. Compound dU‐PhtBu enabled efficient light‐dependent control of catalytic activity, while maintaining thermal stability and reversibility.

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]
, 2011 Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.
