Three-Dimensional Analyses Of Geological Materials On Nanoscale By Electron Tomography
: Electron tomography (ET), an electron-microscopy-based technique that provides three-dimensional (3D) structural information from a tilt series of two-dimensional (2D) projections, has promoted the in-depth investigation of biological molecules in structural biology and the analysis of material structures on the atomic scale in physical sciences. Although ET has developed rapidly as an effective technique wherein atomic-scale resolution has been achieved by using advanced transmission electron microscopy systems, it has not been widely used by the earth and planetary science community. Herein, we verify the applicability of ET in research related to earth and planetary science. The data demonstrate that ET can be used to observe the 3D morphology of mineral grains and 3D distributions of the chemical components of earth and planetary materials. Notably, ET coupled with spectroscopy, including electron energy loss spectroscopy and energy dispersive spectroscopy, is an effective technique for studying the 3D distribution
期刊介绍:
The ATOMIC SPECTROSCOPY is a peer-reviewed international journal started in 1962 by Dr. Walter Slavin and now is published by Atomic Spectroscopy Press Limited (ASPL). It is intended for the rapid publication of both original articles and review articles in the fields of AAS, AFS, ICP-OES, ICP-MS, GD-MS, TIMS, SIMS, AMS, LIBS, XRF and related techniques. Manuscripts dealing with (i) instrumentation & fundamentals, (ii) methodology development & applications, and (iii) standard reference materials (SRMs) development can be submitted for publication.
