From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers

Advanced Functional Materials, EarlyView.
Ultrathin AlOxHy interlayers between aluminum films and polymer substrates significantly improve electro‐mechanical properties of flexible thin film systems. By precisely controlling interlayer thickness using atomic layer deposition, this study identifies an optimal interlayer thickness of 5–10 nm that enhances ductility and delays cracking.

NSM CFRP laminates for the shear strengthening of T section RC beams [PDF]

, 2006
A new strengthening technique for concrete structures failing in shear was developed based on introducing laminate strips of carbon fiber reinforced polymer (CFRP) into slits made on the concrete cover of the lateral faces of the beams to be strengthened.

Conductive Bonding and System Architectures for High‐Performance Flexible Electronics

Advanced Functional Materials, EarlyView.
This review outlines bonding technologies and structural design strategies that support high‐performance flexible and stretchable electronics. Bonding approaches such as surface‐activated bonding and anisotropic conductive films, together with system‐level architectures including buffer layers and island‐bridge structures, possess distinct mechanical ...

Dual‐Layer Living Hydrogel Enables On‐Demand Delivery of Phages and Probiotics for Synergistic Wound Infection Therapy

Advanced Functional Materials, EarlyView.
A dual‐layer living hydrogel, ProΦGel, integrates bacteriophages and probiotics for synergistic wound infection therapy. The outer gelatin‐based matrix releases phages on demand in response to P. aeruginosa infections, while inner alginate beads sustain probiotic delivery.

Experimental evaluation of the diagonal tension test of hollow clay blocks strengthening with (AR) glass fibers

Case Studies in Construction Materials
In many developing countries, masonry infill walls are commonly constructed using hollow clay blocks. Buildings incorporating these infill walls are particularly vulnerable to seismic loads due to the absence of adequate lateral load-resisting elements ...

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

Advanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

A multidisciplinary approach to study precipitation kinetics and hardening in an Al-4Cu (wt. %) alloy

, 2018
A multidisciplinary approach is presented to analyse the precipitation process in a model Al-Cu alloy. Although this topic has been extensively studied in the past, most of the investigations are focussed either on transmission electron microscopy or on ...
