Social entrepreneurship is a growing area of interest among practitioners. Social entrepreneurship meets and satisfies social needs and brings social change through innovative ideas. This study aims to investigate the impact of positivity and empathy of individuals on social entrepreneurial intention. This study considers the mediating role of social entrepreneurial self‐efficacy between the relationship of positivity, empathy, and social entrepreneurial intention. In addition, this study investigates perceived social support as a boundary condition between the relationship of social entrepreneurial self‐efficacy and social entrepreneurial intention. Findings show that positivity and empathy positively influence social entrepreneurial self‐efficacy, which subsequently positively influences social entrepreneurial intention. Furthermore, results show that high perceived social support strengthens the relationship between social entrepreneurial self‐efficacy and social entrepreneurial intention. Discussions and implications based on the study findings are reported.
The amorphous metal boride materials are attractive catalyst for advanced lithium sulfur batteries, but their catalytic mechanism remains unclear. Herein, 2D amorphous Mo-doped cobalt boride (Co 7 Mo 3 B) is designed for the first time as bidirectional sulfur catalysis by rapid chemical reduction. The atom cluster structure of Co 7 Mo 3 B is revealed by theoretical calculation. Electron paramagnetic resonance test further confirms that Co 7 Mo 3 B has interstitial compound structure characteristics. Experimental results show that the porous 2D nanosheets structure and the interaction of Mo, B, Co atoms contribute to enhanced conductivity, high long-chain lithium polysulfides affinity, and reversible Li 2 S nucleation and dissociation, thus accelerating LiPSs reduction and Li 2 S oxidation kinetics. In addition, the interstitial Co 7 Mo 3 B enables intercalation of Li and B during chargingdischarging while keeping the structure stable. As a result, the S cathode with Co 7 Mo 3 B catalyst delivers good life (1000 cycles at 5 C), superior rate performance (10 C). Even at high sulfur areal loading of 6.79 mg cm -2 and electrolyte/sulfur ratio of 5 μL mg -1 , the Co 7 Mo 3 B/S composite cathode still exhibits good areal capacity and capacity retention rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
