TLDR
In this paper, a method for measuring and mapping displacement fields and strain fields from high-resolution electron microscope (HREM) images is developed based upon centring a small aperture around a strong reflection in the Fourier transform of an HREM lattice image and performing an inverse Fourier transformation.About:

Fourier-transform method of fringe-pattern analysis for computer-based topography and interferometry
TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.

TL;DR: It is shown that heat-carrying phonons with long mean free paths can be scattered by controlling and fine-tuning the mesoscale architecture of nanostructured thermoelectric materials, and an increase in ZT beyond the threshold of 2 highlights the role of, and need for, multiscale hierarchical architecture in controlling phonon scattering in bulk thermoeLECTrics.

Strained endotaxial nanostructures with high thermoelectric figure of merit
Kanishka Biswas,Jiaqing He,Qichun Zhang,Guoyu Wang,Ctirad Uher,Vinayak P. Dravid,Mercouri G. Kanatzidis,Mercouri G. Kanatzidis +7 more
TL;DR: This work has experimentally achieved concurrent phonon blocking and charge transmitting via the endotaxial placement of nanocrystals in a thermoelectric material host via crystallographic alignment of SrTe and PbTe lattices.

TL;DR: Atomic-resolution chemical mapping reveals deformation mechanisms in the CrFeCoNiPd alloy that are promoted by pronounced fluctuations in composition and an increase in stacking-fault energy, leading to higher yield strength without compromising strain hardening and tensile ductility.

The correlation averaging of a regularly arranged bacterial cell envelope protein
W. O. Saxton,Wolfgang Baumeister +1 more
TL;DR: An adaptation of the ‘correlation averaging’ method is described which allows reliable and almost fully automatic image averaging in the case of near‐periodic structures notwithstanding the presence of substantial crystal imperfections.

Digital image processing: The semper system
W. O. Saxton,T.J. Pitt,M. Horner +2 more
TL;DR: A fully portable system of programs for image processing, particularly suitable for applications in electron microscopy, that can be run on very small as well as very large computers, and may be extended “indefinitely” as new procedures are developed.
