Wujun Ma,Shaohua Chen,Shengyuan Yang,Wenping Chen,Yanhua Cheng,Yiwei Guo,Shengjie Peng,Seeram Ramakrishna,Meifang Zhu +8 more
TL;DR: In this paper, a hierarchical structured MnO 2 nanowire/graphene hybrid fibers are fabricated through a simple, scalable wet-spinning method, and the hybrid fibers form mesoporous structure with large specific surface area of 139.9m 2 ǫg −1.
Journal ArticleDOI
Flexible all-solid-state asymmetric supercapacitor based on transition metal oxide nanorods/reduced graphene oxide hybrid fibers with high energy density
TL;DR: In this article, an asymmetric supercapacitor was constructed by using MnO2 nanorods/reduced graphene oxide (rGO) hybrid fibers as positive electrode and H3PO4/polyvinyl alcohol (PVA) as electrolyte.
Journal ArticleDOI
Multiscale Humidity Visualization by Environmentally Sensitive Fluorescent Molecular Rotors.
Yanhua Cheng,Jianguo Wang,Zijie Qiu,Xiaoyan Zheng,Nelson L. C. Leung,Jacky W. Y. Lam,Ben Zhong Tang,Ben Zhong Tang +7 more
TL;DR: A visual sensing approach based on fluorescent imaging is presented, by assembling aggregation-induced-emission (AIE)-active molecular rotors into a moisture-captured network; the resulting AIE humidity sensors are compatible with diverse applications, having tunable geometries and desirable architectures.
Journal ArticleDOI
