Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems
Angewandte Chemie, EarlyView.Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Geometry‐Controlled Assembly of Self‐Standing Nanorods With Undisturbed Plasmonics
Advanced Science, EarlyView.This study reports a geometry‐driven assembly strategy to vertically align Au@Ag core–shell nanorods on PS beads. This well‐defined architecture enables the preservation of the intrinsic optical response of individual nanorods. Thus, demonstrate a highly reproducible SERS enhancement with exceptional uniformity.

Electrolyte–Framework Matching in High‐Voltage TEMPO‐COF Cathodes for Lithium Batteries
Advanced Science, EarlyView.TEMPO‐functionalized covalent organic frameworks are investigated as high‐voltage cathodes for lithium batteries. Screening five electrolyte anions identifies lithium difluoro(oxalato)borate (LiDFOB) as the optimal electrolyte, balancing capacity, rate capability, and cycling stability, while buckypaper electrodes achieve high mass loading (40 mg cm−2)

Advanced NanoBiomed Research, EarlyView.This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity
