Environmental Effects on RRAM Cells Based on 2D Halide Perovskite Materials
RRAM offers high speed, scalability, and low power, positioning it as a next‐generation non‐volatile memory. Two‐dimensional halide perovskites show promise due to tunable optoelectronic properties and flexible processing but suffer from environmental sensitivity. This review examines degradation from humidity, temperature, light, and strain, discusses

Discovery of Quinazolone Pyridiniums as Potential Broad-Spectrum Antibacterial Agents
The overprescription of antibiotics in medicine and agriculture has accelerated the development and spread of antibiotic resistance in bacteria, which severely limits the arsenal available to clinicians for treating bacterial infections.

Metal-Free Aziridination of Unactivated Olefins via Transient N-Pyridinium Iminoiodinanes [PDF]
We describe a metal-free aziridination of unactivated olefins to generate N-pyridinium aziridines, which participate in cross-coupling to afford N-aryl aziridines and reductive depyridylation to afford N–H aziridines.

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).

Investigation of the Pyridinium Ylide—Alkyne Cycloaddition as a Fluorogenic Coupling Reaction
The cycloaddition of pyridinium ylides with alkynes was investigated under mild conditions. A series of 13 pyridinium salts was prepared by alkylation of 4-substituted pyridines.

Synthesis and studies on pyridinium pentafluorozirconate and pyridinium oxotetrafluoroniobate
Pyridinium pentafluorozirconate, (C5H5NH)ZrF5, and pyridinium oxotetrafluoroniobate, (CH5NH)NbOF4, have been synthesised by the reaction of pyridinium poly(hydrogen fluoride), PPHF, with ZrOCl2 and Nb2O5, respectively.

Comparative photodynamic inactivation of bioluminescent E. coli by pyridinium and inverted pyridinium chlorins [PDF]
Photodynamic inactivation (PDI) is a therapeutic approach in study due to the ability to reduce or completely eliminate the bacterial strains without the development of resistance mechanisms.
