Nanoscale Insights into the Dynamics of Conductive Filament Growth/Dissolution in 2D Material‐Based Memristors

open access: yesAdvanced Science, EarlyView.
The evolution dynamics of conductive filaments (CFs) in 2D material‐based electrochemical metallization (ECM) memristor are studied under electric fields using in situ transmission electron microscopy. The growth/dissolution pathway is found to be contrary to traditional ECM theory.

Dual Hydrophilic‐Hydrophobic Core Architecture in Soy Glycinin Amyloid Fibrils Revealed by Cryo‐EM

open access: yesAdvanced Science, EarlyView.
While high‐resolution structures of animal and microbial amyloids are extensively characterized, the structural principles underlying plant‐derived amyloids remain largely unexplored. The study addresses this fundamental gap in knowledge by determining the first near‐atomic‐resolution cryo‐EM structures of amyloid fibrils derived from soy glycinin ...

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 ...
