Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

open access: yesAdvanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

Residual Stresses and Micro‐voids Propel Metal Diffusion for Filament‐Based Memristors

open access: yesAdvanced Science, EarlyView.
Introducing non‐reactive nitrogen during silver sputtering enables low‐voltage (<60 mV) switching in memristors via nano‐void formation and residual stresses in the gigapascal range. This promotes sub‐micron filamentation and neuromorphic behaviors, including multi‐peak synaptic responses.

Heterointerface‐Modulated Synthetic Synapses Exhibiting Complex Multiscale Plasticity

open access: yesAdvanced Science, EarlyView.
An asymmetric dual‐gate heterointerface‐regulated artificial synapse (HRAS) is developed, employing distinct ion concentrations and dielectric coupling to form precise dual‐interface channels. Through lateral modulation, HRAS realizes, for the first time, the intricate interplay of lateral inhibition/enhancement and multi‐level short‐ and long‐term ...
