Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach

open access: yesAdvanced Materials, EarlyView.
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Unique Impacts of Scandium Doping on Electrode Performance of P’2‐ and P2‐type Na2/3MnO2

open access: yesAdvanced Materials, EarlyView.
The structural stability during electrochemical cycling for P’2‐Na2/3MnO2 as a positive electrode for of Na‐ion battery is investigated by modulating the materials via metal substitution and varying the degree of Jahn‐Teller distortion. The cycle stability is maximized when combining Sc doping and the lattice distortion, demonstrating > 300 cycles in ...

Linear and Symmetric Artificial Synapses Driven by Hydrogen Bonding for Accurate and Reliable Neuromorphic Computing

open access: yesAdvanced Materials, EarlyView.
Hydrogen‐bond‐driven interface engineering enables highly linear and symmetric artificial synapses based on CsPbI3–PVA hybrids. This strategy suppresses trap states and guides directional ion migration, yielding stable optoelectronic plasticity. The devices achieve ultralow power operation and human‐like learning in neuromorphic networks, offering a ...
