Surface Chemistry of All Inorganic Halide Perovskite Nanocrystals: Passivation Mechanism and Stability Tập 5 Số 8 - 2018
Dandan Yang, Xiaoming Li, Haibo Zeng
AbstractAll inorganic halide perovskite (IHP) nanocrystals (NCs) have emerged as
a new class of optoelectronic materials for various applications. Surface
ligands as surface passivators are essential components of nucleation and growth
processes, photoluminescence quantum yields (PL QY), stability, and
photoelectric applications. In this review, the relationship of perovskite
structure modified is... hiện toàn bộ
MXene‐Based Composites: Synthesis and Applications in Rechargeable Batteries and Supercapacitors Tập 6 Số 8 - 2019
Jian Yang, Weizhai Bao, Pauline Jaumaux, Songtao Zhang, Chengyin Wang, Guoxiu Wang
AbstractThe family of 2D transition metal carbides, nitrides, and carbonitrides
(collectively called MXenes) is rapidly studied since the initial synthesis of
Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has
hydrophilic groups (F, OH, and O), which leads the surface to be negatively
charged. Consequently, the negatively charged surface can facilitate the
compounding of MX... hiện toàn bộ
Specially Wettable Membranes for Oil–Water Separation Tập 5 Số 23 - 2018
Yibin Wei, Hong Qi, Xiao Gong, Shuaifei Zhao
AbstractThe oil–water separation has attracted heightened attention because of
the ever‐increasing amounts of oily water produced from the daily activities of
humans and industrial processes. Membrane technology as an advanced water
purification approach has offered an indispensable option due to its
cost‐effective, energy‐efficient, and easy‐to‐operate characteristics. However,
traditional membra... hiện toàn bộ
Ultrathin MXene/Calcium Alginate Aerogel Film for High‐Performance Electromagnetic Interference Shielding Tập 6 Số 6 - 2019
Zehang Zhou, Jize Liu, Xinxing Zhang, Dong Tian, Zeying Zhan, Canhui Lu
AbstractUltrathin and high‐performance electromagnetic interference (EMI)
shielding materials are urgently demanded for modern microelectronic devices. 2D
metal carbides (MXenes) are considered as a promising EMI shielding material due
to its metallic conductivity. In this study, sodium alginate is applied as
interlayer spacer for Ti3C2Tx nanosheets, which not only prevents the restacking
of lamel... hiện toàn bộ
Flexible Photodetector Based on 2D Materials: Processing, Architectures, and Applications Tập 7 Số 4 - 2020
Tao Dong, João Simões, Zhaochu Yang
AbstractFlexible photodetectors have emerged during the past few years for
applications in healthcare, security, and environmental monitoring. Recently, 2D
materials have started being implemented as functional layers in flexible
photodetector due to their outstanding optoelectronic characteristics paired
with high mechanical flexibility. In this work, the authors analyze the progress

Hierarchical NiS@CoS with Controllable Core‐Shell Structure by Two‐Step Strategy for Supercapacitor Electrodes Tập 7 Số 3 - 2020
Yidong Miao, Xuping Zhang, Zhan Jiang, Yanwei Sui, Jiqiu Qi, Fuxiang Wei, Qingkun Meng, Yezeng He, Yaojian Ren, Zhenzhen Zhan, Zhi Sun
AbstractConstructing hierarchical core‐shell configuration from well‐known metal
sulfides is one way to further tune and utilize unique species. Herein, a novel
core‐shell structure is developed based on CoS deposited on NiS nanosheets,
which involves hydrothermal and electrodeposition method. The micromorphology of
the composite electrode can be optimized by adjusting the cycles of
electrodeposit... hiện toàn bộ
