In this case, the very bulky organic group linked to the tin atom prevented further condensation of the monoorganotin units into distannoxane dimers, which are the building blocks of the Sn12 cluster isolated when butyl groups are used as ligands....
One of the major objectives of cluster science is to discover stable atomic clusters, which may be used as building blocks for cluster-assembled nanomaterials. The discovery and bulk synthesis of the fullerenes have sprouted new research disciplines in chemistry and nanoscience and precipitated intense...
Stannaspherene refers to an icosahedral 12-atom Sn cage cluster (Sn122-) and has also been found to be able to trap all transition metals to form gaseous e... Zhong-Ming,Sun,Hai,... - 《Journal of the American Chemical Society》 被引量: 145发表: 2007年 Sn122‐: Stannaspherene. ...
The Sn10Zn cluster was also pointed out to be highly stable, even it is less abundant than the Sn12Zn in the experimental mass spectra. Consequently, these species were assigned to be magic clusters with some novel characters such as a high symmetry structure and a certain aromaticity. ...
(N=108). In addition, data-driven clustering approach together with the radiomics-based network measurement was carried out to cluster prodromal PD patients into high-/low-risk subtypes. Interestingly, the clustering findings...
☑A two-dimensional metal-organic framework is built from Co3cluster-based node extended by binary mixed linkers. It demonstrates outstanding adsorption capacities for dyes and iodine. ☑一种二维金属有机框架由基于Co3簇的节点构建,并通过二元...
An open-framework bimetallic chalcogenide structure K 3Rb 3Zn 4Sn 3Se 13 built on a unique [Zn 4Sn 3Se 16] 12 cluster: synthesis, crystal structure, ion ex... An open-framework bimetallic chalcogenide structure K 3Rb 3Zn 4Sn 3Se 13 built on a unique [Zn 4Sn 3Se 16] 12 cluster...
The building block in this structure is a [Zn4Sn3Se16]12− cluster which consists of four ZnSe4 and three SnSe4 tetrahedra connected through corner-sharing of Se atoms. The 3D network contains intersecting channels running parallel to the crystallographic [2 1 1], [1-1-1] ...
Large, larger, largest—A family of cluster-based tantalum copper aluminides with giant unit cells. I. Structure solution and refinement. Acta Crystallogr. Sect. B 2009, 65, 308–317. [CrossRef] [PubMed] 12. Conrad, M.; Harbrecht, B.; Weber, T.; Jung, D.Y.; Steurer, W. Large,...
此外,研究还识别出两组典型的临床特征:一组是与血小板相关的增加群体(PLT cluster),另一组是与红细胞相关的减少群体(RBC cluster)。这些发现表明,pt-DVT患者存在大规模的代谢失调,并且PLT和PCT可能成为临床诊断pt-DVT的有前景的标志物。图1本研究的设计与分析工作流程...
