Understanding intracranial aneurysm sounds via high-fidelity fluid-structure-interaction modelling

Communications Medicine, 2023
Background Since the 1960s, the origins of intracranial aneurysm bruits and musical murmurs have been debated, with proposed mechanisms ranging from self-excitation (i.e., resonance) by stable pulsatile flow, to vibration caused by unstable (laminar ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

Full-Scale Collision Behavior of a Polyurea-Coated RC Intrusion Protection Wall for High-Speed Train Derailment

Buildings
High-speed train derailments can cause severe vehicle collisions with rail bridges and adjacent infrastructure; however, full-scale evidence for the collision response of trackside intrusion-protection walls and for material measures that limit concrete ...

Seismic behaviour of a large-scale concrete-block retaining wall [PDF]

E3S Web of Conferences, 2019
In this study, an inclined model experiment and finite element analyses were conducted to evaluate the failure mode and seismic response of a dry-type large-scale concrete-block retaining wall (LCBW). In the experiment, the objective was to reproduce the

Interfacial Failure and Self‐Healing in Solid‐State Batteries

Advanced Materials, EarlyView.
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‐

Sustainable Plant‐Based Water Repellent Coatings Using Hydrophobic Pine and Palm Pollen

Advanced Materials Interfaces, EarlyView.
A novel formulation strategy for creating superhydrophobic coatings using plant‐derived waxes and chemically treated pine and palm pollen. By employing acid modification, the hydrophobicity of the pollen surface is enhanced, resulting in water contact angles exceeding 150°.
