3D‐Printed Ion‐Conductive Hydrogels with Tunable Mechanical–Electrical Properties for Multimodal Sign Language Recognition

Advanced Science, EarlyView.
This work successfully fabricated ion‐conductive hydrogels with low hysteresis and high conductivity using 3D printing technology. By adjusting the component ratios, the properties of the hydrogels can be tuned to meet diverse sensing requirements. Finally, a multimodal sensing sign language recognition system was constructed based on this hydrogel ...

Asymmetric Mass Transport in Polybromide Ionic Liquids and Its Impact on Dual‐Plating Zinc Bromine Batteries

Advanced Science, EarlyView.
This study elucidates mass transport dynamics within polybromide ionic liquids in dual‐plating zinc–bromine batteries using operando impedance spectroscopy. The findings reveal that sluggish polybromide transport during dissolution contrasts with rapid bromide transport during charging.

A Low‐Permeability TEMPO‐Phosphate as an Anionic Posolyte for Aqueous Redox‐Flow Batteries

Angewandte Chemie, EarlyView.
Phosphate groups are appended to TEMPO‐based active materials for use in aqueous redox‐flow batteries. In addition to improving water‐solubility, these dianionic groups are strongly repelled by the cation‐exchange membrane, thus greatly reducing TEMPO crossover.

GPX4 Inhibitor Resistance and Metastatic Features in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study establishes breast cancer cell lines that are resistant to glutathione peroxidase 4 inhibitors (GPX4i) in vitro and investigates the metastatic capacity of the GPX4i‐resistant versus parental lines in vivo. GPX4i‐resistant cells survive upon intravenous injection, but lose capacity to spontaneously metastasize.

Amphiphile of Bis-Quaternary Ammonium Salt

Journal of Japan Oil Chemists' Society, 2000
Amphiphiles of symmetrical bis-quaternary ammonium salts possessing ammonium groups, with methyl as head group, dodecyl and aralkyl as hydrophobic groups, and connected by an alkanediyl were synthesized. Aralkyls are p-heptylbenzyl and 8-phenyloctyl (corresponding ammonium salts are designated “phenylene type” and “phenyl type”, respectively).
