Organoselenium Ligand Enabled Selective Electron Tuning for Switchable Hydrogen Evolution Reaction.

Unraveling the electronic structure of metal complexes can bring various catalytic possibilities for hydrogen evolution reaction (HER). However, the electronic effect of metal and ligands modulating and switching the reaction center for HER has yet to be comprehensively analyzed. Herein, we report nickel selenoether electrocatalysts which show tunable reaction centers (nickel or ligand) for HER using mild weak acetic acid in less deprotonating DMF solvent.

Optimization of Polymers for Organic Solar Cells: Effects of Alkyl, Fluorinated and Thiophenated Chains.

This paper explores optimization strategies for polymeric materials in organic solar cells (OSCs) with the focus on varying alkyl side chain, addition of fluorine atom, and thiophenated derivatives onto polymer. As such, it outlines the significance of renewable energy sources and the potential of photovoltaic technologies, particularly organic photovoltaics (OPVs). Objectives include factors affecting power conversion efficiency (PCE), open-circuit voltage (Voc), aggregation tendencies, and optoelectronic properties in OPVs.

Role of Adenosine A1 Receptor in Sleep Deprivation-Induced Neuroinflammation: Insights on Rapid Eye Movement Sleep and Fear Extinction Memory Recall in Rats.

Introduction: Sleep deprivation (SD), stemming from a myriad of aetiologies, is a prevalent health condition frequently overlooked. It typically impairs memory consolidation and synaptic plasticity, potentially through neuroinflammatory mechanisms and adenosinergic signalling. It is still unclear whether the adenosine A1 receptor (A1R) modulates SD-induced neurological deficits in the hippocampus.

Isolated absent pulmonary valve with intact ventricular septum in a young child: A rare case report.

Absent pulmonary valve syndrome, commonly linked with tetralogy of Fallot and ventricular septal defect, is a rare congenital condition. It is exceedingly rare to have an isolated absent pulmonary valve with an intact ventricular septum without cardiovascular shunt lesions, such as an atrial/ventricular septal defect or patent ductus arteriosus. This report presents a case of such rarity involving a young child with recurrent lower respiratory tract infections.
