Electron tomography and holography in materials science

TLDR
An overview of the techniques of electron tomography and electron holography is presented and their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences are demonstrated.
Abstract
The rapid development of electron tomography, in particular the introduction of novel tomographic imaging modes, has led to the visualization and analysis of three-dimensional structural and chemical information from materials at the nanometre level. In addition, the phase information revealed in electron holograms allows electrostatic and magnetic potentials to be mapped quantitatively with high spatial resolution and, when combined with tomography, in three dimensions. Here we present an overview of the techniques of electron tomography and electron holography and demonstrate their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences.

Three-dimensional visualization of dislocation-precipitate interactions in a Al–4Mg–0.3Sc alloy using weak-beam dark-field electron tomography

TL;DR: In this article, weak-beam images of dislocations interacting with particles acquired over a large angular range were used to reconstruct tomograms, which were then used as the basis to construct a 3D model of the dislocation structure.

Correlated 3D Nanoscale Mapping and Simulation of Coupled Plasmonic Nanoparticles

TL;DR: Electron tomography in combination with electron energy-loss spectroscopy experiments and simulations was used to unravel the interplay between structure and plasmonic properties of a silver nanocuboid dimer, overcomes the need for geometrical assumptions or symmetry restrictions of the sample in simulations and paves the way for detailed investigations of realistic and complex plAsmonic nanostructures.

Representation of a Function by Its Line Integrals, with Some Radiological Applications

TL;DR: In this paper, a method for finding a real function in a finite region of a plane given its line integrals along all straight lines intersecting the region was given, and the solution found is applicable to three problems of interest for precise radiology and radiotherapy: (1) the determination of a variable x-ray absorption coefficient in two dimensions, (2) the distribution of positron annihilations when there is an inhomogeneous distribution of the positron emitter in matter, and (3) a variable density of matter with constant chemical composition, using the energy loss
