12 lip 2020 · Abstract. Zinc–air batteries deliver great potential as emerging energy storage systems but suffer from sluggish kinetics of the cathode oxygen redox reactions that render unsatisfactory cycling lifespan.
24 mar 2021 · Here, self-supported oxygen vacancy-rich ZnO (ZnO-V) porous nanosheets are constructed using the electrochemical cyclic voltammetric (CV) reduction method and adopted as catalysts for urea electrosynthesis by using CO 2 and nitrite contaminants as feedstocks (Figure 1).
29 maj 2021 · Abstract. Crystalline, amorphous, and crystalline–amorphous materials have become three important electrode materials for the bottleneck oxygen-evolving reaction (OER) in the promising hydrogen-producing technology of water splitting. With the rapid development of in situ/ex situ characterizations, the understanding of active sites in ...
Li Wei the Magistrate (2001) Chinese television historical comedy-drama starring Xu Zheng as a young Li Wei, an illiterate county magistrate who would become one of the most prominent officials during 18th-century Qing dynasty.
5 lis 2021 · Metasurfaces have provided a promising approach to enhance the nonlinearity at subwavelength scale, but usually suffer from a narrow bandwidth as imposed by sharp resonant features. Here, we counterintuitively report a broadband, enhanced second-harmonic generation, in nanopatterned hyperbolic metam ….
