Advanced Intelligent Discovery, EarlyView.Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

Self‐Assembled (Aza)BODIPY Dyes for Biomedical in Vivo Imaging
Angewandte Chemie International Edition, EarlyView.This minireview classifies (aza)BODIPY dyes according to their molecular stacking modes and aggregate types (H‐, oblique‐, or J‐type) in aqueous media, correlating these features with their multimodal imaging performance. By linking molecular design, exciton coupling, and pathway‐dependent assembly, we provide a framework for engineering next ...
