Henriette Gavlshøj Mortensen

The basement below the Interdisciplinary Nanoscience Center is filled with futuristic looking machines. They are big and complicated, but able to reveal the smallest of secrets: The structure of nanoparticles. During her PhD studies, Henriette Gavlshøj Mortensen worked with one of these machines: The hyper-SAXS. It generates X-rays using liquid metal and shoots them at nano-samples. Here the X-rays scatter and forms a distinct pattern on a detector. Henriette Gavlshøj Mortensen has implemented a robust analytical method using the scattering pattern to explore the shape and size of particles that form spontaneously in a solution. Using that method she found that sustainably produced surfactants behave similar to conventional surfactants and that proteins can unfold and cover nanoparticles. She also investigated the effect of mixing ratios on shape of the formed nanoparticles.

The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
