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 ...

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

NIR‐Harvesting Upconversion CsPbI3 Perovskite Solar Cells with Dye‐Hybridized Nanoparticles

open access: yesAdvanced Optical Materials, EarlyView.
To enhance solar energy conversion efficiency, dye‐sensitized upconversion nanoparticles (UCNPs) with CsPbBr3 shell layers are developed and integrated them into lead halide perovskite solar cells. These UCNPs convert near‐infrared (NIR) light into visible light, enabling the utilization of a broader solar spectrum, thereby increasing photocurrent ...
