Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

open access: yesAdvanced 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).

Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non‐invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high‐field systems remain costly and inaccessible for most ...
