Summary: This study reports luminescent conjugated polymers with boron-fused azomethine structure and tridentate ligands, which can respond to acid vapor and are used for film-type sensors. The acid responsiveness is due to the lone-pair electrons on the nitrogen atom in the boron-fused azomethine unit. The polymer films exhibit red shifts in emission wavelengths under acid vapor and reversible responses. Furthermore, the films show unique luminescent color changes due to environmental sensitivity. The bilayer films of the BAm polymer coated with poly(n-butyl methacrylate) show vapochromic luminescence with blue shifts depending on exposure time, allowing for the evaluation of solvent-vapor permeability.

Summary: This study investigated the association between psychosocial stress and oxidative stress using a Trier Social Stress Test. The results showed that oxidative stress metrics significantly increased in both a healthy control group and a schizophrenia group after acute psychosocial stress. By using an Ir-reducing capacity assay, the researchers identified five oxidative stress metrics that were consistent with expectations, and these metrics could discern statistically significant increases in oxidative stress levels in both groups 90 minutes after the stressor.

Summary: This study presents a low temperature synthesis method for pre-lithiated cathodes in thin film batteries using a co-sputtering process. The analysis reveals the presence of multiple phases of LixV2O5 in the thin films, which remain unchanged after electrochemical cycling. The co-sputtering process allows for tuning of lithium content and achieves a highly lithiated state. The thin film solid-state battery prototype using the lithiated vanadium oxide as a cathode demonstrates a relatively high coulombic efficiency.

Summary: Catechol-based materials in redox-based bioelectronics possess diverse properties and can transduce near infrared (NIR) radiation into heat. The study shows that catechol-chitosan films can reversibly respond to both NIR and redox inputs, suggesting the independent flow of energy through catechol-based materials via redox and electromagnetic modalities. These findings highlight the potential of catecholic materials for bio-device communication, offering both short-range redox communication and long-range electromagnetic communication.
