Hydrogen‐Bond‐Mediated Asymmetric Catalysis Tập 3 Số 3 - Trang 516-532 - 2008
Xinhong Yu, Wei Wang
AbstractThe utilization of hydrogen bonding as an activation force has become a
powerful tool in asymmetric organocatalysis. Significant advances have been made
in the recent past in this emerging field. Due to space constraints, this Focus
Review summarizes only the key aspects with an emphasis on catalysis based on
chiral ureas and thioureas, diols, and phosphoric acids. The examples provided

Current Advances in Quantum‐Dots‐Based Photoelectrochemical Immunoassays Tập 12 Số 21 - Trang 2780-2789 - 2017
Jian Shu, Dianping Tang
AbstractAs a newly developed technique, photoelectrochemical (PEC) immunoassays
have attracted great attention in recent years because of their low cost and
desirable sensitivity. Because the detection signal originates from the
photoelectric conversion of photoelectric materials, the appearance and
application of quantum dots (QDs), which possess unique photophysical properties
and regulated opto... hiện toàn bộ
Luminescent Noble Metal Nanoclusters as an Emerging Optical Probe for Sensor Development Tập 8 Số 5 - Trang 858-871 - 2013
Xun Yuan, Zhentao Luo, Yong Yu, Qiaofeng Yao, Jianping Xie
AbstractIn the past few years, highly luminescent noble metal nanoclusters
(e.g., Au and Ag NCs or Au/Ag NCs in short) have emerged as a class of promising
optical probes for the construction of high‐performance optical sensors because
of their ultrasmall size (<2 nm), strong luminescence, good photostability,
excellent biocompatibility, and unique metal‐core@ligand‐shell structure. In
this Focus ... hiện toàn bộ
The Mitsunobu Reaction: Origin, Mechanism, Improvements, and Applications Tập 2 Số 11 - Trang 1340-1355 - 2007
Tracy Yuen Sze But, Patrick H. Toy
AbstractThe Mitsunobu reaction is a widely used and versatile method for the
dehydrative oxidation–reduction condensation of an acid/pronucleophile usually
with a primary or secondary alcohol that requires the combination of a reducing
phosphine reagent together with an oxidizing azo reagent. The utility of this
reaction stems from the fact that it is generally highly stereoselective and
occurs wi... hiện toàn bộ
Triazole: the Keystone in Glycosylated Molecular Architectures Constructed by a Click Reaction Tập 2 Số 6 - Trang 700-708 - 2007
Alessandro Dondoni
AbstractThe copper(I)‐catalyzed modern version of the Huisgen‐type azide–alkyne
cycloaddition to give a 1,4‐disubstituted 1,2,3‐triazole unit is introduced as a
powerful ligation method for glycoconjugation. Owing to its high
chemoselectivity and tolerance of a variety of reaction conditions, this highly
atom‐economic and efficient coupling reaction is especially useful for the
effective construct... hiện toàn bộ
Photocatalytic Advanced Oxidation Processes for Water Treatment: Recent Advances and Perspective Tập 15 Số 20 - Trang 3239-3253 - 2020
Huan Liu, Chengyin Wang, Guoxiu Wang
AbstractNowadays, an ever‐increasing variety of organic contaminants in water
has caused hazards to the ecological environment and human health. Many of them
are persistent and non‐biodegradable. Various techniques have been studied for
sewage treatment, including biological, physical and chemical methods.
Photocatalytic advanced oxidation processes (AOPs) have received increasing
attention due to... hiện toàn bộ
Inorganic Metal Hydroxide Nanoparticles for Targeted Cellular Uptake Through Clathrin‐Mediated Endocytosis Tập 4 Số 1 - Trang 67-73 - 2009
Jae‐Min Oh, Soo‐Jin Choi, Go‐Eun Lee, Jung‐Eun Kim, Jin‐Ho Choy
AbstractLayered double hydroxides (LDHs) are biocompatible materials which can
be used as drug‐delivery nanovehicles. In order to define the optimum size of
LDH nanoparticles for efficient cellular uptake and drug‐delivery pathway, we
prepared different sized LDH nanoparticles with narrow size distribution by
modulating the crystal growth rate, and labelled each LDH particle with a
fluorophore usi... hiện toàn bộ
A Water‐Stable Terbium(III)–Organic Framework as a Chemosensor for Inorganic Ions, Nitro‐Containing Compounds and Antibiotics in Aqueous Solutions Tập 14 Số 20 - Trang 3694-3701 - 2019
Junhua Wei, Wei Wang, Min‐Le Han, Bo Li, Shan Liu, Ya‐Pan Wu, Lufang Ma, Dong‐Sheng Li
AbstractEffective detection of organic/inorganic pollutants, such as
antibiotics, nitro‐compounds, excessive Fe3+ and MnO4−, is crucial for human
health and environmental protection. Here, a new terbium(III)–organic framework,
namely [Tb(TATAB)(H2O)]⋅2H2O (Tb‐MOF,
H3TATAB=4,4′,4′′‐s‐triazine‐1,3,5‐triyltri‐m‐aminobenzoic acid), was assembled
and characterized. The Tb‐MOF exhibits a water‐stable 3D... hiện toàn bộ
Chemical Regulation of Carbon Quantum Dots from Synthesis to Photocatalytic Activity Tập 8 Số 5 - Trang 1035-1041 - 2013
Shengliang Hu, Ruixue Tian, Lingling Wu, Qing Zhao, Jinlong Yang, Jun Liu, Shirui Cao
AbstractCarbon quantum dots (CQDs) were synthesized by heating various carbon
sources in HNO3 solution at reflux, and the effects of HNO3 concentration on the
size of the CQDs were investigated. Furthermore, the oxygen‐containing surface
groups of as‐prepared CQDs were selectively reduced by NaBH4, leading to new
surface states. The experimental results show that the sizes of CQDs can be
tuned by ... hiện toàn bộ
