Formamidinium-based perovskites (FA perovskites) often incorporate methylammonium chloride (MACl) to stabilize the α-FAPbI phase and prevent formation of the δ phase. However, MACl undergoes deprotonation and reacts with FA, leading to the generation of unstable byproducts that can cause component degradation and negatively impact the device performance. In this study, we introduce ethylenediaminetetramethylenephosphonic acid as a corrosion inhibitor, which effectively prevents the formation of these byproducts and stabilizes α-FAPbI.

Cognitive decline is one of the most significant non-motor symptoms of Parkinson's disease (PD), with executive dysfunction (EDF) being the most prominent characteristic of PD-associated cognitive deficits. Currently, lack of uniformity in the conceptualization and assessment scales for executive functions impedes the early and accurate diagnosis of executive dysfunction in PD. The neurobiological mechanisms of executive dysfunction in PD remain poorly understood.

In this study, three novel derivatives of benzo[b]thiophene-2-carbaldehyde (BTAP1, BTAP2, and BTAP3) were successfully synthesized and comprehensively characterized using spectroscopic techniques including FTIR, UV-VIS, HNMR, and CNMR. Thermal analysis through TGA and DTA demonstrated remarkable thermal stability with a maximum threshold at 270 °C. Spectroscopic investigations revealed π → π* transitions in all compounds, attributed to the conjugated system comprising benzothiophene rings connected to bromophenyl/ aminophenyl/phenol rings via α, β-unsaturated ketone bridges.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a highly prevalent liver pathology in need of novel pharmacological treatments to complement lifestyle-based interventions. Nuclear receptor agonists have been under scrutiny as potential pharmacological targets and as of today, resmetirom, a thyroid hormone receptor b agonist, is the only approved agent. The dual PPAR α and δ agonist elafibranor has also undergone extensive clinical testing, which reached the phase III clinical trial but failed to demonstrate a beneficial effect on MASLD.
