We report passively Q-switched pulse operation through an erbium-doped fiber laser (EDFL) utilizing graphene oxide/titania (GO/TiO) nanorods as a saturable absorber. The GO/TiO nanorods were fabricated using a Sol-gel-assisted hydrothermal method. The optical and physical characterization of the GO/TiO was then characterized using a field-emission-scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and diffuses reflectance spectroscopy (DRS).

Article Synopsis
  • This study investigates how servant leadership influences employees' service performance through their sense of obligation to their leaders.* -
  • Data was collected from 312 manager-subordinate pairs in private hospitals in Karachi, and analysis was done using advanced structural equation modeling.* -
  • The findings confirm that felt obligation serves as a key link between servant leadership and employee performance, while performance pressure does not significantly alter this relationship.*

MXene, regarded as cutting-edge two-dimensional (2D) materials, have been widely explored in various applications due to their remarkable flexibility, high specific surface area, good mechanical strength, and interesting electrical conductivity. Recently, 2D MXene has served as a ideal platform for the design and development of electrocatalysts with high activity, selectivity, and stability. This review article provides a detailed description of the structural engineering of MXene-based electrocatalysts and summarizes the uses of 2D MXene in hydrogen evolution reactions, nitrogen reduction reactions, oxygen evolution reactions, oxygen reduction reactions, and methanol/ethanol oxidation.
