Rigid Supramolecular Aramid Nanotubes as Catalyst Supports

open access: yesAdvanced Materials, EarlyView.
Molecular nanotube self‐assemblies with high aspect‐ratios and stiffness are demonstrated as nanocatalyst supports. The extended dimensions and tunable surface chemistries of the nanotubes enable tethered gold nanoparticle catalysts to remain dispersed in solution and to be easily recovered through simple filtration.

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

open access: yesAdvanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.

Cu and Cu‐30Ni Alloy as Anti‐Viral Materials for High‐Touch Surfaces: Efficacy in a Simulated Public Environment with Frequent Cleaning Practices

open access: yesAdvanced Materials Interfaces, EarlyView.
This study evaluates the antiviral efficacy and corrosion behavior of pure copper and Cu‐30Ni alloy on high‐touch surfaces under simulated public conditions with periodic cleaning. Copper shows faster virus inactivation due to higher ion release, while Cu‐30Ni offers better aesthetic durability.

AI‐Enhanced Gait Analysis Insole with Self‐Powered Triboelectric Sensors for Flatfoot Condition Detection

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
The given research presents an innovative insole‐based device employing self‐powered triboelectric nanogenerators (TENG) for flatfoot detection. By integrating TENG tactile sensors within an insole, the device converts mechanical energy from foot movements to electrical signals analyzed via machine learning, achieving an 82% accuracy rate in flatfoot ...

Event‐Driven Elongation Monitor for Soft Devices Using a Deformation‐Activated Piezoconductive Switch

open access: yesAdvanced Materials Technologies, EarlyView.
A stretchable, event‐driven strain sensor with low energy consumption is developed using positive piezoconductive composites. These composites remain insulative when relaxed, while they become conductive when stretched. Their electrical characteristics are modifiable by the nickel's weight ratio and cross‐sectional geometry. Strain‐induced switching is
