O/C Ratio‐Driven Fluorescence Enhancement in Cellulose‐Derived Carbon Quantum Dots: Mechanistic Insights into Reaction Pathways

open access: yesAdvanced Science, EarlyView.
Three types of CQDs are prepared from cellulose and its derivatives via hydrothermal carbonization. An increase in the atomic O/C ratio from 0.25 to 0.61 results in a nearly seven‐fold enhancement in QY. DFT calculations verify this mechanism. Further, this study elucidates the formation pathways of cellulose‐derived CQDs and proposes a fluorescence ...

Mechanical Force Storage and Reprogramming Hydrogel for Scarless Repair of Sports Joint Wounds

open access: yesAdvanced Science, EarlyView.
Inspired by the energy conversion of tendons, the “energy transit station” hydrogel is designed. The hydrogel not only shields stress concentration in sports injuries, but also reprograms energy forms to provide reasonable biomimetic contraction for wounds.

The Genetic Wiring of Plant Trichomes: From Initiation to Fate Specification

open access: yesAdvanced Science, EarlyView.
Plant trichomes are not just simple hairs but metabolic powerhouses shaped by complex genetic programs. While the MYB‐bHLH‐WD40 module is well studied in Arabidopsis, recent findings reveal that HD‐Zip IV transcription factors drive multicellular and glandular trichome development through dose‐dependent mechanisms.

Interface Chemistry and Reaction Pathway Regulation for Boosted Redox Kinetics in Aqueous Zn–S Batteries

open access: yesAdvanced Science, EarlyView.
The reaction properties of both electrodes in aqueous Zn‐S batteries is regulated by a tetramethylurea electrolyte additive. It preferentially adsorbs on the sulfur surface and coordinates to Zn2+, thereby altering their reaction process. The energy barrier is reduced and nucleation is promoted, which accelerates reaction kinetics.
