Welcome to the Joint ESS – MAX IV Science Colloquium Webcast on May 13 – 'Smart microgels: Structure, properties & potential applications'

Thomas Hellweg, Professor of Physical and Biophysical Chemistry at Bielefeld University.

Due to the Covid19 pandemic we are temporarily shifting the popular colloquium series to webcast format. This month, we will hear Professor Thomas Hellweg tell us about front-line research into smart microgels and how neutrons and X-rays can provide unique insights into these enigmatic materials. 

Time: Wednesday 13 May 2020, 15:15 –16:15 CET

As always, the speaker is happy to receive questions;  e-mail your questions during the talk to sciencequestions@ess.eu and they will be addressed at the end of the seminar.


Smart microgels: Structure, properties & potential applications

Microgels are soft, deformable and penetrable objects with an internal gel-like structure. They respond reversibly and sometimes dramatically to external stimuli like temperature, pressure or pH, which makes them appear almost life-like. This behavior promises practical functions as sensors or actuators in sub-micrometer devices, and has also captured the interest of scientists in many disciplines. In this colloquium, we’ll learn about the chemistry and physics of several such smart microgels and some promising applications.

About the Joint ESS – MAX IV Science Colloquia
Co-organised by MAX IV Laboratory and ESS, the aim of these colloquia is to bring the science made possible by neutrons and synchrotron radiation into focus, and to bring people at ESS and MAX IV and the local science community together. They are held every month, with the venue alternating between MAX IV and ESS. Always on a Wednesday, always at 15:15 – and always with coffee and sweets served at 15:00. Due to the need for social distancing we are temporarily shifting the colloquia to a web-based platform, and although we will miss the face-to-face interaction we hope that this can attract a wider audience than usual!
