VISION is developing and applying a new unique platform for visualizing catalytic nanoparticles and reactions at the atomic-level by integrating cutting-edge electron microscopy, microfabricated nanoreactors, nanoparticle synthesis and computational modelling. This approach enables new, direct operando observations that are urgently needed to advance mechanistic insight into catalytic processes at the atomic-scale.

The interdisciplinary approach aims at relating the atomic-scale structure, dynamics and functions of isolated, single nanoparticles in both thermal catalysis and electrocatalysis as a radical new approach for developing new and more efficient catalysts needed to tackle the environmental challenges of our time.

VISION’s hosts a new one-of-a-kind electron microscope facility, located in DTU’s new "Climate Challenge Laboratory" building. The new laboratory will host the VISION center, the Surface Physics and Catalysis section, the CatTheory section and the Pioneer Center, CAPeX, as a vibrant collaborative research environment with internationally leading scientists in the fields of catalysis and power-to-X.

Responsibilities and tasks

Position 1: You will work quantitatively with the atomic structure and functionality of single nanoparticles in thermal catalysis. The tasks can include:

• Preparation of microfabricated nanoreactors with single or few nanoparticles for catalysis of chemical reactions in gas phase.
• Operando studies of single nanoparticles using atomic-resolution transmission electron microscopy techniques.
• Development of new ultrasensitive and quantitative methods for investigations of gas-surface interactions on nanoparticles at the atomic-scale.
• Relating the three-dimensional atomic surface structure and catalytic functions of single nanoparticles.
• Exploring the structure-function relations to develop strategies for designing uniquely active catalyst nanoparticles for sustainable chemical processes.

Position 2: You will work quantitatively with the dynamic behaviour of single nanoparticles in thermal catalysis. The tasks can include:

• Visualization of single nanoparticles in thermal catalysis using time-resolved, atomic-resolution transmission electron microscopy techniques.
• Development of quantitative image analysis to extract dynamic information encoded in single and series of atomic-resolved images of single nanoparticles.
• Investigation of dynamic processes at the heterogeneous surface of single nanoparticles as catalytic reactions progress.
• Understanding of atomic mechanisms and kinetics to develop strategies for stabilizing uniquely active but metastable surface motifs of nanoparticles as catalysts for sustainable chemical processes.

In both positions, you will collaborate closely with a group of PhD students, postdocs and international leading scientists, all working at the technological edge of modern electron microscopy for advancing catalysis science.

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

We favor candidates with a degree in physics, chemistry or materials science. Candidates should have documented skills in atomic-resolution electron microscopy and, preferably, experience with operando electron microscopy experiments, microfabricated devices, catalysis or surface science. Experience in scientific programming, e.g. using Python, is important. The candidate should also have demonstrated outstanding problem-solving skills as well as very good communication skills in both spoken and written English.
