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

Synthesis of MoS2 and MoSe2 Films with Vertically Aligned Layers
TL;DR: This communication presents a synthesis process to grow MoS2 and MoSe2 thin films with vertically aligned layers, thereby maximally exposing the edges on the film surface, and confirmed their catalytic activity in a hydrogen evolution reaction (HER), in which the exchange current density correlates directly with the density of the exposed edge sites.

Towards stable catalysts by controlling collective properties of supported metal nanoparticles
TL;DR: This work presents an alternative strategy based on control over collective properties, revealing the pronounced impact of the three-dimensional nanospatial distribution of metal particles on catalyst stability and paves the way towards the rational design of practically relevant catalysts and other nanomaterials with enhanced stability and functionality.

Coherent X-ray diffraction imaging of strain at the nanoscale.
Ian K. Robinson,Ross Harder +1 more
TL;DR: New X-ray diffraction techniques, which take advantage of the latest synchrotron radiation sources, can be used to obtain quantitative three-dimensional images of strain, leading to new knowledge of how nanomaterials behave within active devices and on unprecedented timescales.

Three-dimensional atomic imaging of crystalline nanoparticles
Sandra Van Aert,Kees Joost Batenburg,Kees Joost Batenburg,Marta D. Rossell,Rolf Erni,Gustaaf Van Tendeloo +5 more
TL;DR: 3D reconstruction of a complex crystalline nanoparticle at atomic resolution is reported, which helps close the gap between the atomic resolution achievable in two-dimensional electron micrographs and the coarser resolution that has hitherto been obtained by conventional electron tomography.
