摘要:	摘要： Membranes and their size-selective filtering properties are universal in nature and their behavior is exploited to design artificial membranes suited for, e.g., molecule or nanoparticle filtering and separation. Exploring and understanding penetration and transmission mechanisms of nanoparticles in thin-film systems may provide new opportunities for size selective deposition or embedding of the nanoparticles. Here, we demonstrate an unexpected finding that the sieving of metal nanoparticles through atomically thin nonporous alkali halide films on a metal support is size dependent and that this sieving effect can be tuned via the film thickness. Specifically, relying on scanning tunneling microscopy and spectroscopy techniques, combined with density functional theory calculations, we find that defect-free NaCl films on a Au(111) support act as size-dependent membranes for deposited Au nanoclusters. The observed sieving ability is found to originate from a driving force toward the metal support and from the dynamics of both the nanoparticles and the alkali halide films. 其他題名： Nano Lett 出版者： United States: American Chemical Society 出版日期： 2016-05-11 出處： Nano Letters, 2016-05, Vol.16 (5), p.3063-3070 資源來源： American Chemical Society Journals 版權： Copyright © 2016 American Chemical Society 識別號： ISSN: 1530-6984 識別號： EISSN: 1530-6992 識別號： DOI: 10.1021/acs.nanolett.6b00126 識別號： PMID: 27074132
