Graphene-based electrodes with rational structural design have shown extraordinary prospect for harvesting enhanced electrical double-layer capacitance of micro-supercapacitors (MSCs). In this study, a facile fabrication method for flexible planar MSCs based on hierarchical graphene is...

Die Studie enthält Daten von zwei Umfragen: eine in privaten Haushalten und die andere bei Unternehmen in der VR China. Die Ergebnisse werden in einen versicherungstheoretischen Kontext gebracht und geben Aufschluß über das Verhalten bei Risiko und der Einstellung zur Versicherung. (HWWA/DÜI)

We examine whether and how the exercising of rights by the regulatory minority shareholder impacts firms' cost of equity. Using a hand-collected sample from the CSISC, a novel regulatory investor protection institution controlled by the China Securities Regulatory Commission, we find that the...

A novel NiCoPt ternary-alloy dispersed by 2D ultrathin NiCo nanosheets has been designed and successfully synthesized for oxygen reduction (ORR) with high activity and long-term stability. The NiCoPt/NiCo nanostructures are prepared through the artificial active collodion membrane by one-step...
