The Department of Materials and Environmental Chemistry (MMK) at Stockholm University (www.mmk.su.se ) announces a postdoc stipend to work on a project related to scanning transmission electron microscopy imaging of delicate specimens.

Transmission electron microscopy has evolved into an essential tool in materials and life science characterization. Keys to an increased understanding of the properties of new materials are embedded in their structures and hence knowledge herein is essential in the evolution of materials chemistry. Recent advances in the aberration-corrected scanning transmission electron microscope are opening up for structural studies at the atomic scale of delicate specimens sensitive to the electron beam.

The aim of this project is to utilize and develop protocols for imaging of electron beam-sensitive materials at the atomic scale using scanning transmission electron microscopy (STEM). Techniques such as integrated differential phase contrast (iDPC) imaging and 4-dimensional (4D) STEM will be explored for the purpose of structural characterization of delicate specimens, where these techniques are essential.1-2 It will be essential to obtain a fundamental understanding of both data acquisition and interpretation for these techniques. The project will involve studies of nanoporous materials, such as metal-organic frameworks, as well as biomaterials, e.g. cellulose and chitin. The work will be carried out in collaboration with leading groups in materials development.
