This paper describes a strategy for preparing free-standing reduced graphene oxide@Si nanoparticles (rGO@Si NPs) composite membranes. Graphene oxide (GO) was and self-assembled synchronously with of silicon (Si on metal surface the film subsequently used in lithium-ion battery (LIB). work several important novel aspects reported technology. Firstly, membrane has flexible self-supporting structu...

Abstract The reaction kinetics at a triple‐phase boundary (TPB) involving Li + , e − and O 2 dominate their electrochemical performances in Li–O batteries. Early studies on catalytic activities /e /O interfaces have enabled great progress energy efficiency; however, localized TPBs within the cathode hamper innovations battery performance toward commercialization. Here, effects of homogenized ai...

Urbanization is one of man’s greatest challenges. Its handling requires a better understanding orderliness in the demographic–socioeconomic–entrepreneurial domain human settlements. Operating business enterprises are manifestations successful entrepreneurship, which characteristic interest here. Non-linear entrepreneurial proportionalities can be detected through use log–log regressions (power ...

Appropriate glass systems can provide efficient transparent radiation shielding. The current study involved the preparation of system with a composition xEu2O3-(15-x)ZnO-10CaO-35PbO-40P2O5 (where x = 0, 1, 2, 3, and 4 wt.% Eu2O3). formation phase was confirmed using X-ray diffraction (XRD). analyzed physical structural parameters, such as optical conductivity (σopt), refractive index (n), band ...
