Job Description

This postdoc position will develop your expertise in the physics and chemistry of polymeric self-organization phenomena. The position at DTU Chemistry is affiliated with the project Packing Frustration in ABC Starblock Polymers and the focus of the project is to study how the detailed structure of the individual blocks A, B and C influence the self-organization behavior. An ABC star block polymer is a material where polymer A, B, and C is connected to a common point. The project involves the study of a carefully chosen selection of ABC-stars. The purity of the stars we investigate is pivotal and thus competences within polymer analysis and in particular chromatography is important. The synthesis of the materials are conducted in collaboration with a PhD-project already affiliated with the project. The properties of the ABC-stars and especially the structures formed will be studied using scattering and imaging techniques. Competences with in electron microscopy, AFM, and small angle scattering is very welcome. We are interested in establishing understanding of the relation between molecular properties - polarity and conformation - and the structures of the bulk ABC-star materials. In the beginning of the post doc the focus will be establishing chromatographic equipment for analysis of the star including option for size exclusion chromatography and chromatography under critical conditions. However, the availability of the ABC stars is also pivotal but as the project moves forward the focus will shift towards the structures formed.

Responsibilities and qualifications
You will be responsible for the characterization and purification of ABC-star polymers using primarily chromatographic methods. The project budget contain a reasonable funds to upgrade/or acquire equipment for this task. It is the main task of a PhD-students in the project to synthesize the ABC-star but you are expected to be involved in this task as well. Once suitable ABC-stars are available you will be responsible for the physical characterization the ABC star e.g., with respect to transition from ordered to disordered state - typically investigated with rheology - and the structure og the ABC star sample - typically using electron microscopy and small-angle-X-ray scattering. The microscopy will take place at DTU whereas small-angle scattering is done in collaboration with project partners. 

We are looking for a candidate with strong competences in experimental polymer chemistry and physics with emphasis structure elucidation especially in selforganized soft-matter such as e.g. block copolymers 

You will primarily work at DTU Chemistry. However, the overall project is conducted in collaboration with groups at the Niels Bohr Institute at the University of Copenhagen and Department of Science and Environment at Roskilde University and you should expect that some experiments regarding structural characterization of ABC star bulk and surface structures will take place at the collaborating institutions.

Teaching and supervision of undergraduate and graduate students is also a responsibility.

As a formal qualification, you must hold a PhD degree (or equivalent). 

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. 

Salary and terms of employment

Kristoffer Almdal's group is part of the Physical and Biophysical Chemistry Section at DTU Chemistry. The group works in several areas. The core is to identify and synthesize (polymer) molecules that can answer specific questions often identified in cross-disciplinary collaborations. The group has a long standing effort studying self-organization phenomena in block copolymers most recently and continuing with the present project focused on ABC-star polymer systems. The project is inspired by the recent discovery of complex crystal phases and quasicrystals in diblock copolymers.

DTU Chemistry is responsible for the chemistry teaching at DTU at all levels. The research at DTU encompass basic as well as applied research in a diversity of area.
