Journal ArticleDOI
Fabrication of Single‐ and Multilayer MoS2 Film‐Based Field‐Effect Transistors for Sensing NO at Room Temperature
Hai Li,Zongyou Yin,Qiyuan He,Hong Li,Xiao Huang,Gang Lu,Derrick Wen Hui Fam,Alfred Iing Yoong Tok,Qing Zhang,Hua Zhang +9 more
TL;DR: Although the single-layer MoS(2) device shows a rapid response after exposure to NO, the current was found to be unstable, and these FET devices can be used as gas sensors to detect nitrous oxide.
Journal ArticleDOI
Lanthanide-doped NaxScF3+ x nanocrystals : crystal structure evolution and multicolor tuning
Xue Teng,Yihan Zhu,Wei Wei,Shuchao Wang,Jingfeng Huang,Rafik Naccache,Wenbo Hu,Alfred Iing Yoong Tok,Yu Han,Qichun Zhang,Qu-Li Fan,Wei Huang,John A. Capobianco,Ling Huang +13 more
TL;DR: Because of the small radius of Sc(3+), Na(x)ScF( 3+x):Yb/Er nanocrystals show different UC emission from that of NaYF(4):YB/Ernanocrystals, which broadens the applications of rare-earth-based nanomaterials ranging from optical communications to disease diagnosis.
Journal ArticleDOI
Nanostructured metallic transition metal carbides, nitrides, phosphides, and borides for energy storage and conversion
Khang Ngoc Dinh,Qinghua Liang,Chengfeng Du,Chengfeng Du,Jin Zhao,Alfred Iing Yoong Tok,Hui Mao,Qingyu Yan +7 more
TL;DR: In this article, the progress in energy storages and conversions that employ metal-like transition metal-based nanostructures (MLTMNs) is summarized and discussed.
Journal ArticleDOI
Hydrothermal synthesis of CeO2 nano-particles
TL;DR: In this paper, the precursors were adjusted to a basic (pH 10) and acidic medium before hydrothermal treatment at various durations of 6, 12, 18, and 24 hours at 250°C using a Teflon-lined hydrotherm bomb.
Journal ArticleDOI
Surface modification of ZnO nanocrystals
TL;DR: In this article, five types of capping agents: 3-aminopropyl trimethoxysilane (Am), tetraethyl orthosilicate (TEOS), mercaptosuccinic acid (Ms), 3-mercaptoprocessor-tricyclic acid (MTA), trimethoxide (TOC), and polyvinylpyrrolidone (Pv) were added at the first ZnO precipitation time to limit the particle growth.
