Seminar: Defects And Their Association: The “Hidden Factor” Behind The Material’s Properties
Blowhole defect in a cast iron part.
The need to comprehend and even embrace defects is not only a matter of life philosophy. It has many crucial implications. Dr. Artem Abakumov of the University of Antwerp , Belgium, discusses in his guest lecture “Defects and Their Association”, the “hidden factor” behind materials’ properties.
When: October 2, 2014; 13.30 – 15.00
Where: Beijing-1 Auditorium, China cluster; Skolkovo School of Management
SEMINAR ABSTRACT:
The macroscopic behavior of many materials largely depends on the nature and concentration of the defects, their mutual interaction and ordering patterns. Association of the defects can lead to complex microstructural states that are strikingly different from an averaged picture based on random distributions of defect species.
Often such short- or long-range ordered states are “hidden” because of high spatial inhomogeneity of the ordered states or intricate patterns of occupational and displacive incommensurate modulations. In this talk I will demonstrate that unexpected ordering patterns of defects can be uncovered in many well-characterized materials with a combination of advanced local and bulk structure characterization techniques and modern crystallographic approaches.
The pivotal role of intersite repulsion, local strain, lone electron pair effect and Jahn-Teller distortion in the collective behavior of the structural defects will be exemplified using the mixed ionic-electronic conductor Sr4Fe6O12 with the perovskite and rock-salt intergrowth structure, Pb-doped anion-deficient derivative of the multiferroic BiFeO3 perovskite and cation-ordered layered rock-salt type Na-ion battery material NaMnO2, with the emphasis on the link between the defect structure and the properties.
With these examples, I will also illustrate how powerful the modern transmission electron microscopy methods can be in gathering the structural and chemical information on the atomic scale.

Seminar May 5: Cracking the Cracks in Crystalline Materials
They say that those ‘perfect’ diamonds are forever.
‘Flawless’ snowflakes are endlessly changing. And a pinch of table salt can turn your dreary sandwich into an ideal snack. But crystals are imperfect. Ask Dr. Alexander Shapeev from the UNiversity of Minnesota who devotes his research to computing minuscule faults in grand crystals.

Title: «COMPUTATIONAL METHODS FOR CRYSTALLINE DEFECTS: CONSTRUCTION, ANALYSIS, AND BENCHMARKING»
SEMINAR ABSTRACT: Defects, defined as irregularities in the periodic arrangement of atoms, determine various important properties of crystalline materials. Such crucial features are plasticity or failure.
Computing defects such as dislocations or cracks is often challenging, because the spatial and temporal scales accessible for direct molecular simulations are limited. Dr. Shapeev’s talk will be devoted to efficient methods for computing crystalline defects. He will focus on atomistic-to-continuum (AtC) coupling, a popular approach utilizing atomistic resolution near the defect core while using the continuum model to resolve the elastic far-field.
Nobody is perfect. Not even crystals
In his talk Dr. Alexander Shapeev will
- Give a brief introduction to crystalline defects and AtC coupling.
- Report one of the recent developments in construction of a consistent energy-based AtC coupling method.
- Present a mathematical theory of how to optimize and compare the performance of existing methods.
The first part of the talk will be devoted to his past research on computing static properties of defects, such as atomistic configuration or formation energy. In the second part, Alexander will speak about the present research and future plans on dynamics of defects and finite temperature.
