The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

Aqueous Lithium Hydroxide Chemistry Based on Hierarchically Assembled Hydrogenated Borophene/Cobalt‐Nickel Compounds for Rechargeable High‐Performance Supercapattery

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous lithium‐ion storage has been demonstrated using a hierarchically assembled hydrogenated borophene/cobalt‐nickel compound as a supercapattery electrode. Reducible hydrogenated borophene generates undercoordinated oxygen, which is redox‐active for lithiation and hydrogenation during the discharging process following the lithium hydroxide ...

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).
