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

Magnetism In-Situ TEM
TL;DR: The development of magnetism in-situ TEM corresponds to the progress in nano-scale research and it cannot be isolated with the development of electron microscopy as discussed by the authors , and the most advanced TEM can easily achieve a spatial resolution below 0.5 Å, which was beyond imagination 100 years ago.

New Types of Three-Dimensional Vortices in the Heisenberg Model
A. B. Borisov,D. V. Dolgikh +1 more
TL;DR: In this paper, the Heisenberg model for an isotropic magnet is considered and a substitution that reduces the corresponding equations to equations with a simpler geometric interpretation is applied, which describes a new magnetic structure comprised of two straight intersecting vortex filaments, which change the topological charge after intersection.
Error bounds for discrete tomography
TL;DR: In this paper, the authors derived a series of computable upper bounds that can be used to guarantee the quality of a reconstructed binary image, which is also valid for bounding the error on higher resolution binary reconstructions from low resolution scans.

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
