Accession number: 20103113112869 Title: High resolution electron microscopy: A powerful tool to characterize nanotubes Authors: Ruiz-González, M.L.1 ; González-Calbet, J.M.1 Author affiliation: 1 Departamento de Química Inorgánica, Facultad de Químicas, Universidad Complutense, 28040-Madrid, Spain Corresponding author: Ruiz-González, M. L. Source title: Key Engineering Materials Abbreviated source title: Key Eng Mat Volume: 441 Monograph title: Advanced Bioceramics in Nanomedicine and Tissue Engineering Issue date: 2010 Publication year: 2010 Pages: 95-119 Language: English ISSN: 10139826 CODEN: KEMAEY ISBN-10: 0878492704 ISBN-13: 9780878492701 Document type: Conference article (CA) Publisher: Trans Tech Publications Ltd, Laubisrutistr.24, Stafa-Zuerich, CH-8712, Switzerland Abstract: The atomic resolution of an electron microscope in terms of both image and analysis requires an electron probe/beam smaller than an atom in size yet intense enough to provide a sufficiently strong signal to perform rapid EELS spectrum acquisition. The correction of the spherical aberration of the objective lens can be dealt with an electromagnetic hexapole system. When employing a negative CS value combined with a certain overfocus setting, not only a substantial contrast improvement is achieved but low-nuclear charge elements can also be imaged at bright atom contrast features in the vicinity of high-nuclear charge atoms. Besides the synthesis of tubular structures from 2D compounds a growing interest to obtain nanotubes of 3D compounds has been displayed in the last years. The evolution of microcopy has been parallel to the new discoveries in material science prompted by the need of going deeper on the solid behavior.
