Kai Le,Wang Zhou,Fenglong Wang,Qi Wang,Qian Shao,Vignesh Murugadoss,Vignesh Murugadoss,Shide Wu,Wei Liu,Jiurong Liu,Qiang Gao,Zhanhu Guo +11 more
TL;DR: The robust electrochemical properties indicate the composites as promising electrodes for electrochemical energy storage devices.
Journal ArticleDOI
MOF-derived hierarchical core-shell hollow iron-cobalt sulfides nanoarrays on Ni foam with enhanced electrochemical properties for high energy density asymmetric supercapacitors
Kai Le,Mengjiao Gao,Wei Liu,Jiurong Liu,Wang Zhou,Fenglong Wang,Vignesh Murugadoss,Vignesh Murugadoss,Vignesh Murugadoss,Shide Wu,Tao Ding,Zhanhu Guo +11 more
TL;DR: In this article, a hierarchical core-shell hollow iron-cobalt sulfides nanoarrays supported on conductive nickel foam (Fe-Co-S/NF) were fabricated using metal-organic frameworks (MOFs) as the sacrificial templates.
Journal ArticleDOI
Bimetal oxide-derived flower-like heterogeneous Co/MnO@C composites with synergistic magnetic–dielectric attenuation for electromagnetic wave absorption
Dongmei Xu,Nannan Wu,Kai Le,Fenglong Wang,Wang Zhou,Wu Lili,Wei Liu,Ancheng Ouyang,Jiurong Liu +8 more
TL;DR: In this article, the effect of electromagnetic parameters on the absorption performance with the variation of Co proportion was analyzed, and it was found that the magnetic properties, conductivity and electromagnetic parameters were readily manipulated by the Co proportion, with the purpose of achieving favorable impedance matching and attenuation performance.
Journal ArticleDOI
Controlled sulfidation towards achieving core-shell 1D-NiMoO4 @ 2D-NiMoS4 architecture for high-performance asymmetric supercapacitor
Mengjiao Gao,Kai Le,Dongmei Xu,Wang Zhou,Fenglong Wang,Wei Liu,Huijun Yu,Jiurong Liu,Chuanzhong Chen +8 more
TL;DR: In this paper, an asymmetric supercapacitor with NiMoO4 nanorod as core and NiMoS4 nanosheet as shell with controlled sulfidation manner was obtained by one-step hydrothermal method.
Journal ArticleDOI
Fluorescent Phthalocyanine–Graphene Conjugate with Enhanced NIR Absorbance for Imaging and Multi-Modality Therapy
TL;DR: A covalently connected silicon phthalocyanine and graphene oxide conjugate SiPc-GO is designed and synthesized via conjugation reaction to render stability and displays intrinsically fluorescence and synchronous photothermal-photodynamic therapy (PTT/PDT) effect, along with 3-fold higher near-infrared (NIR) absorbance comparing to pristine GO.
