4-Cyanopyridinium chloride

open access: yesActa Crystallographica Section E, 2012
In the crystal structure of the title salt, C6H5N2+·Cl−, the pyridinium cation links to the Cl− anion via an N—H...Cl hydrogen bond. Weak C—H...Cl interactions also occur.

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).

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity

Rapid Electrophilic Cysteine Arylation with Pyridinium Salts

open access: yesBioconjugate Chemistry, 2022
Here, we present a series of fluorinated cationic reagents that enable rapid arylation of cysteine under mild conditions compatible with proteins and peptides. The highly polarized C-F bond and attractive nucleophile-electrophile Coulombic interactions substantially accelerate cysteine arylation, leading to unusually high rate constants on the order of
