Molecular beam epitaxy of antiperovskite oxides

APL Materials, 2022
Antiperovskites, or inverse perovskites, have recently emerged as a material class with a plethora of promising electronic properties. This Perspective describes the molecular beam epitaxy (MBE) growth of oxide antiperovskites Sr3PbO and Sr3SnO.

THE INFLUENCE OF SEGREGATION ON MORPHOLOGY OF THE (100) Cu-4 at. % Mn ALLOY SURFACE [PDF]

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2012
The influence of thermostimulated segregation on morphology of Cu-22,5 at. % Mn alloy surface was investigated by low energy electron diffraction means. Surface structural perfection of the alloy is estimated by the diffraction reflection.

High bunch charge low-energy electron streak diffraction

Structural Dynamics
For time-resolved diffraction studies of irreversible structural dynamics upon photoexcitation, there are constraints on the number of perturbation cycles due to thermal effects and accumulated strain, which impact the degree of crystal order and spatial

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Data on the annealing of NbTiVZr at 1200 °C with slow cooling rate

Data in Brief, 2019
The data presented here is complementary to the publication entitled “High temperature, low neutron cross-section high-entropy alloys in the Nb-Ti-V-Zr system” [1]. A homogenization methodology with slower cooling rate (∼2 °C/min) was performed.
