1. 什么东西还尚未发现/系统研究
A. However,systems that are sufficiently stable and efficient for practical use have not yet been realized.
B. Nevertheless,for conventional nanostructured MTMOs as mentioned above, some problematic disadvantages cannot be overlooked.（Angew. Chem. Int. Ed.2014,53, 1488 – 1504）
C. There are relatively few studies devoted to determination of cmc values for block copolymer micelles. (Macromolecules 1991, 24, 1033-1040)
D. This might be the reason why, despite of the great influence of the preparation on the catalytic activity of gold catalysts, no systematic study concerning the synthesis conditions has been published yet. (Applied Catalysis A: General
2002, 226, 1–13)
E. These possibilities remain to be explored.
F. Further effort is required to understand and better control the parameters dominating the particle surface passivation and resulting properties for carbon dots of brighter photoluminescence. (J. Am. Chem. Soc., 2006, 128 , 7756–7757)
2. 由于/因为...
A. Liquid ammonia is particularly attractive as an alternative to water due to its stability in the presence of strong reducing agents such as alkali metals that are used to access lower oxidation states.
B. The unique nature of the cyanide ligand results from its ability to act both as a σ donor and a π acceptor combined with its negativecharge and ambidentate nature.
C. Qdots are also excellent probes for two-photon confocal microscopy because they are characterized by a very large absorption cross section (Science 2005, 307, 538-544).
D. As a result of the reductive strategy we used and of the strongbonding between the surface and the aryl groups, low residualcurrents (similar to those observed at a bare electrode) wereobtained over a large window of potentials, the same as for theunmodified parent GC electrode. (J. Am. Chem. Soc. 1992, 114, 5883-5884)
E. The small Tafel slope of the defect-rich MoS2 ultrathin nanosheets is advantageous for practical applications, since it will lead to a faster increment of HER rate with increasing overpotential.(Adv. Mater., 2013, 25: 5807–5813)
F. Fluorescent carbon-based materials have drawn increasing attention in recent years owing to exceptional advantages such as high optical absorptivity, chemical stability, biocompatibility, and low toxicity.(Angew. Chem. Int. Ed., 2013, 52: 3953–3957)
G. On the basis of measurements of the heat of immersion of water on zeolites, Tsutsumi etal. claimed that the surface consists of siloxane bondings and is hydrophobicin the region of low Al content. (Chem. Rev. 2002, 102, 3641?3666)
H. Nanoparticle spatial distributions might have a large significance for catalyst stability, given that metal particle growth is a relevant deactivation mechanism for commercial catalysts.
3. ...很重要
A. The inhibition of additional nucleation during growth, in other words, the complete separation of nucleation and growth, is critical(essential, important) for the successful synthesis of monodisperse nanocrystals. (Nature Materials 3, 891 - 895 (2004))
B. In the current study, Cys, homocysteine (Hcy) and glutathione (GSH) were chosen as model thiol compounds since they play important (significant, vital, critical) roles in many biological processes and monitoring of these thiol compounds is of great importance for diagnosis of diseases.(Chem. Commun., 2012, 48, 1147-1149)
C. This is because according to nucleation theory, what really matters in addition to the change in temperature ΔT (or supersaturation) is the cooling rate.(Chem. Soc. Rev., 2014, 43, 2013-2026)
研之成理面向所有感兴趣的朋友征集专栏作家，主要包括专业软件（比如Digital Micrograph, TIA, Photoshop，Chemoffice，Material studio等）和基础知识（XRD结构精修，热分析，核磁，程序升温实验，同步辐射，质谱，AFM，STM）的分享，以及相关领域最新文献赏析。目前，由于小编人数有限，总结的周期会比较长，如果有更加专业的人来分担一部分的话，应该可以让大家更快更好地学到更多内容。
