Description

Postdoctoral position, Study of the crystallization of organic molecules using transmission electron microscopy - 2020BAPFWETEF117

The EMAT research group at the Faculty of Science (University of Antwerp) is seeking to fill a full-time (100%)

Postdoctoral position in the area of the study of the crystallization of organic molecules using transmission electron microscopy under the supervision of Prof Sandra Van Aert and Prof Sara Bals .

The main goal of the project is to develop and apply transmission electron microscopy techniques to investigate the crystallization of organic molecules. The occurrence of two or more crystal structures for a given molecule, a phenomenon which is called polymorphism, is ubiquitous to various classes of synthetic and natural compounds. Examples of polymorphism are known in numerous application fields, such as food, explosives, pigments, semiconductors, fertilizers, and pharmaceutical drugs. Different crystal structures, so-called polymorphs, of the same compound exhibit sometimes very different physical properties, chemical reactivity, and biological functions. For instance, the polymorphs might differ in solubility ruining the pharmaceutical effect of one or more of the polymorphs. Understanding and controlling polymorphism is therefore very important. Simple questions, such as "How many polymorphs has a given compound’" or "What drives polymorph selection’", remain unanswered yet. In this scientific context, scientists have started to explore the occurrence of substrate-induced polymorphism, i.e. the formation of polymorphs that exist only in the vicinity of solid substrates. In particular, this project has the ambition to elucidate how positional and orientational order of molecules propagate from the substrate to the upper crystal layers. In this manner, the project will gain a fundamental understanding of polymorphism at the interface with solid substrates.

Job description

  • You will develop and apply transmission electron microscopy techniques to investigate electron beam-sensitive materials including scanning electron diffraction and exit wave reconstruction;
  • You have the opportunity to supervise student projects;
  • You are enthusiastic and greatly interested in transmission electron microscopy and materials science;
  • You publish scientific articles related to the research project of the assignment;
