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.read more

TL;DR: It is found that geometrically-confined skyrmions are able to adopt a wide range of sizes and ellipticities in a nanostripe that are absent in both thin films and bulk materials and can be created from a helical magnetic state with a distorted edge twist in a simple and efficient manner.

TL;DR: In this paper, the basic properties of the different types of core/shell nanoparticles including a large variety of heterostructures are discussed, and general concepts based on solid state physics are considered for material selection and for identifying criteria linking the core and shell structure and its resulting properties.

Quasi-four-dimensional analysis of dislocation interactions with grain boundaries in 304 stainless steel
Josh Kacher,Ian M. Robertson +1 more
TL;DR: In this article, diffraction contrast electron tomography was applied to dynamic experiments involving dislocation interactions with grain boundaries for the first time, and two applications were shown: the first is concerned with post-mortem analysis of dislocation interaction with grain boundary and illustrates the usefulness of the tomography technique for defect analysis; the second is in conjunction with in situ straining experiments in which the dynamics of dislocations interactions withgrain boundaries are observed directly and the resulting structure visualized three-dimensionally.

Improving tomographic reconstruction from limited data using Mixed-Scale Dense convolutional neural networks
TL;DR: The Mixed-Scale Dense convolutional neural network architecture is proposed, which was specifically designed to avoid these disadvantages, to improve tomographic reconstruction from limited data, and shows that Mixed- Scale Dense networks are able to significantly improve reconstruction quality even with severely limited data.

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
