Accepted 25 September 2019

Cluster mining: an approach for determining core structures of metallic nanoparticles from atomic pair distribution function data

A novel approach for finding and evaluating structural models of small metallic nanoparticles is presented

Accepted 17 September 2019

Elastic propagation of fast electron vortices through amorphous materials

This article describes the scattering behavior of electron vortices inside amorphous samples. It focuses on the vortex purity, net angular momentum transfer, and statistical variations due to random beam and atom positions.

Accepted 15 September 2019

Data-driven approach for synchrotron X-ray Laue microdiffraction scan analysis

A novel data-driven approach for synchrotron Laue X-ray microdiffraction scans is presented based on machine learning techniques.

Accepted 8 September 2019

A parameter-free double-shear theory for lath martensite

In analogy to the original phenomenological theory of martensite crystallography, a double-shear theory for lath martensite is proposed which chooses the shearing systems as those that are macroscopically equivalent to double twinning. Using only the additional assumptions of overall small shape strain magnitude and a condition of maximal compatibility, this approach naturally gives rise to {5 5 7}γ habit planes and orientation relationships close to the Kurdjumov–Sachs model.

Relativistic correction of atomic scattering factors for high-energy electron diffraction

Relativistic electron diffraction depends on linear and quadratic terms in the electric potential, the latter being neglected in the frequently used relativistically corrected Schrödinger equation. Conventional tabulations for electron scattering and its large-angle extrapolations can be amended in closed form by a universal correction based on the screened Coulomb potential squared.

Accepted 2 September 2019

Normally supportive sublattices of crystallographic space groups

Subgroups of 3D crystallographic space groups that are also normal subgroups of 3D space groups have long been of interest. For each arithmetic crystal class of 3D space groups, the sublattices capable of supporting such subgroups are tabulated.
