Aryl-Acetylene Layered Hybrid Perovskites in Photovoltaics.

Metal halide perovskites have shown exceptional potential in converting solar energy to electric power in photovoltaics, yet their application is hampered by limited operational stability. This stimulated the development of hybrid layered (two-dimensional, 2D) halide perovskites based on hydrophobic organic spacers, templating perovskite slabs, as a more stable alternative. However, conventional organic spacer cations are electronically insulating, resulting in charge confinement within the inorganic slabs, thus limiting their functionality.

Optimization of solar water pumping systems through a combined approach based on MPPT-Bat and DTC.

This paper investigates enhancing the efficiency of solar water pumping systems (SWPS) by implementing a Maximum Power Point Tracking technique based on the Bat Metaheuristic Optimizer (MPPT-bat) for the photovoltaic generator (PVG) side, coupled with Direct Torque Control (DTC) for the induction motor powering the pump. Unlike traditional techniques, which make no compromise between tracking speed, oscillation and robustness. The integration of the MPPT-bat represents a significant advance, making it possible to improve PVG performance whatever the weather conditions.

A comparative study of stress amongst different hierarchies of paediatric dental providers.

Stress, a state of mental or emotional strain or tension brought on by challenging or demanding events might hamper a dentist's ability to react quickly and prudently. Their ability to deal with difficult patients may also be compromised, especially when dealing with frightened or anxious people. The main goal of this study was to survey a wide range of dental professionals from different backgrounds, including undergraduates, general practitioners and specialists, and determine how much stress each group was experiencing and how it affected both the participants and the treated patients.

The sustainability effects of two reading interventions on Saudi nursing students' comprehension of scientific research.
