Cobalt Tungstate Characterization Using Matryoshka‐Structure Filter

Advanced Engineering Materials, EarlyView.
The green synthesis of cobalt tungstate (CoWO4) using natural polymerizing agents from agar–agar and commercial produces environmentally friendly materials with tunable structural and electromagnetic properties. X‐ray diffraction and Rietveld refinement correlate crystal structure with microwave transmission losses in Matryoshka‐type filters.

Scalable Robotic Laser Texturing of Tilted Microanchors for Direction‐Independent Metal–Polymer Joining

Advanced Engineering Materials, EarlyView.
A robot‐assisted laser processing method is proposed that enables the formation of surface‐tilted microanchors on metal substrates to improve metal–polymer joining. Using a six‐axis robotic platform, the laser beam's incidence angle, scanning path, and interline pitch can be precisely controlled, allowing the deliberate overlap of heat‐affected zones ...

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

Advanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Enhancing Fatigue Performance by Tuning of Residual Stresses in Welded Joints through Nanometallic Multilayer

Advanced Engineering Materials, EarlyView.
This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...
