Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

open access: yesAdvanced Functional Materials, EarlyView.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Interface Effects in Ultrathin Silicon on Insulator Films

open access: yesAdvanced Functional Materials, EarlyView.
This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Synergistic Cu‐Fe Interactions Enhance Phase Transformation Kinetics Toward High‐Performance CuFeS2‐Based All‐Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...
