On October 8th I visited the 2MILab and its director Dr. Matthew Fielden at the Royal Technical University (KTH) in Stockholm. Main purpose of my visit was to learn about the infrastructure for surface area and porosity measurements as well as a few other techniques and general organizational aspects. The 2MILab still hosts working instrumentation for mercury intrusion porosity which is a method capable of measuring pore sizes larger than 100 nm which are not accessible with gas adsorption. Mercury is, however, largely banned for use and requires special permits and health checks of the users. At the same time there are no alternative methods that work for all kinds of samples and it becomes increasingly difficult to find working MIP instrumentation. (Alternatives to mercury are being studied, for example in this recent work)
It was in fact my first visit to KTH and it was very interesting a have a short look around the campus, though is was grey and rainy, so I did not see too much. I hope my next visit will be on a sunny day.

This was my third stop on my "Sweden Sorption Tour", that I hope to have the opportunity to continue next year (a thank you to my division at Chalmers that makes this possible).
