Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

Advanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Laser‐Welded Cellulose‐Carbon Nanotube Nanocomposites as a 3D Scaffold of Si Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A Si anode comprising entangled networks of cellulose and SWCNT (C‐CNT) nanocomposites as an anode electrode for a high‐performance LIB is realized by fully utilizing the generated microstructure of a novel conductive 3D scaffold via a low‐temperature and eco‐friendly process. Additionally, localized heating via photo‐thermal conversion can be utilized

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.
