Top‐Down and Bottom‐Up Approaches in Engineering 1 T Phase Molybdenum Disulfide (MoS2): Towards Highly Catalytically Active MaterialsChemistry - A European Journal - Tập 22 Số 40 - Trang 14336-14341 - 2016
Chun Kiang Chua, Adeline Huiling Loo, Martin Pumera
AbstractThe metallic 1 T phase of MoS2 has been widely identified to be
responsible for the improved performances of MoS2 in applications including
hydrogen evolution reactions and electrochemical supercapacitors. To this aim,
various synthetic methods have been reported to obtain 1 T phase‐rich MoS2.
Here, the aim is to evaluate the efficiencies of the bottom‐up (hydrothermal
reaction) and top‐do... hiện toàn bộ
Self‐Templating Construction of Hollow Amorphous CoMoS4 Nanotube Array towards Efficient Hydrogen Evolution Electrocatalysis at Neutral pHChemistry - A European Journal - Tập 23 Số 52 - Trang 12718-12723 - 2017
Weiyi Wang, Xiang Ren, Shuai Hao, Zhiang Liu, Fengyu Xie, Yadong Yao, Abdullah M. Asiri, Liang Chen, Xuping Sun
AbstractEnvironmentally friendly electrochemical hydrogen production needs the
development of earth‐abundant catalyst materials for the hydrogen evolution
reaction with high activity and durability at neutral pH. In this work, the
self‐templating construction of a hollow amorphous CoMoS4 nanotube array on
carbon cloth (CoMoS4 NTA/CC) is reported, using hydrothermal treatment of a
Co(OH)F nanowire ... hiện toàn bộ
Unprecedented Living Olefin Polymerization Derived from an Attractive Interaction between a Ligand and a Growing Polymer ChainChemistry - A European Journal - Tập 9 Số 11 - Trang 2396-2403 - 2003
Makoto Mitani, Takashi Nakano, Terunori Fujita
AbstractTi complexes incorporating fluorine‐containing phenoxy–imine chelate
ligands (fluorinated Ti‐FI catalysts) have been demonstrated to induce an
unprecedented living polymerization effect with both ethylene and propylene,
through an attractive interaction between the fluorine atom in the ligand and a
β‐hydrogen atom on the growing polymer chain. With the aid of this attractive
interaction, h... hiện toàn bộ
Synthesis, Structure, Spectroscopic, and Electrochemical Properties of Highly Fluorescent Phosphorus(V)–meso‐TriarylcorrolesChemistry - A European Journal - Tập 18 Số 20 - Trang 6386-6396 - 2012
Avijit Ghosh, Mangalampalli Ravikanth
AbstractThe synthesis, spectroscopic, and electrochemical properties of seven
new PV–meso‐triarylcorroles (1–7) are reported. Compounds 1–7 were prepared by
heating the corresponding free‐base corroles with POCl3 at reflux in pyridine.
Hexacoordinate PV complexes of meso‐triarylcorroles were isolated that contained
two axial hydroxy groups, unlike the PV complex of
8,12‐diethyl‐2,3,7,13,17,18‐hexa... hiện toàn bộ
Aura of CorrolesChemistry - A European Journal - Tập 15 Số 34 - Trang 8382-8394 - 2009
Iris Aviv‐Harel, Zeev Gross
AbstractCorroles display distinctive structural, spectroscopic, and
photophysical properties, as well as some exceptional chemical reactivities that
are not shared by other molecules. In addition, low‐valent metal complexes are
extremely reactive when chelated by corroles and the opposite holds for the
high‐valent counterparts. One aim of this account is to provide a thorough
understanding of the ... hiện toàn bộ
Ru‐Catalyzed Branched versus Linear Selective C3‐Alkylation of 2‐Aroylbenzofurans with Acrylates via CH ActivationChemistry - A European Journal - Tập 20 Số 26 - Trang 7884-7889 - 2014
Yadagiri Kommagalla, Kolluru Srinivas, Chepuri V. Ramana
AbstractThe carbonyl‐directed C3H activation and alkylation of
2‐aroylbenzo[b]furans with acrylates occurs selectively either in a linear or
branched fashion, depending on the catalyst employed; [Ru(p‐cymene)Cl2]2 or
Ru(PPh3)3Cl2, respectively. Two alternate pathways—funded upon the differences
in steric and electronic preferences of these two complexes—is proposed for the
selectivity of linear v... hiện toàn bộ
Recent Advances in the Chemistry and Biology of PodophyllotoxinsChemistry - A European Journal - Tập 23 Số 19 - Trang 4467-4526 - 2017
Yu Xiang, Zhiping Che, Hui Xu
AbstractPodophyllotoxin and its related aryltetralin cyclolignans belong to a
family of important products that exhibit various biological properties (e.g.,
cytotoxic, insecticidal, antifungal, antiviral, anti‐inflammatory, neurotoxic,
immunosuppressive, antirheumatic, antioxidative, antispasmogenic, and
hypolipidemic activities). This Review provides a survey of podophyllotoxin and
its analogues ... hiện toàn bộ
Interstitial Zn Atoms Do the Trick in Thermoelectric Zinc Antimonide, Zn4Sb3: A Combined Maximum Entropy Method X‐ray Electron Density and Ab Initio Electronic Structure StudyChemistry - A European Journal - Tập 10 Số 16 - Trang 3861-3870 - 2004
Fausto Cargnoni, Eiji Nishibori, Philippe Rabiller, Luca Bertini, G. Jeffrey Snyder, Mogens Christensen, Carlo Gatti, Bo B. Iversen
AbstractThe experimental electron density of the high‐performance thermoelectric
material Zn4Sb3has been determined by maximum entropy (MEM) analysis of
short‐wavelength synchrotron powder diffraction data. These data are found to be
more accurate than conventional single‐crystal data due to the reduction of
common systematic errors, such as absorption, extinction and anomalous
scattering. Analysi... hiện toàn bộ
