We are happy to be part of Stockholm University student recruitment campaign and decorate metro stations around Stockholm.



December - 2023

We are happy to join the MSCA Doctoral Network NanoRAM (HORIZON-TMA-MSCA-DN). NanoRAM brings together people and organisations from across the world to train a new generation of scientists in the development and application of newly developed manipulation and characterisation nanotools in soft matter research.

Mathias was awarded Best Oral Presentation at the SCANDEM2023.

Wow.



June - 2023

In collaboration with the group of Ass. Prof. Mika Sipponen at Stockholm University we have shown how lignin nanoparticles can adapt the colors of the rainbow when arranged in ordered mesostructures.

April - 2023

We have developed a new zirconium ellagate MOF, SU-102, with promising properties for the uptake of contaminants of emerging concern, in this case pharmaceuticals.
Inspiring collaboration with Dr. Inge (Stockholm University), Dr. Horcajada (IMDEA, Madrid) and the Swedish Environmental Research Institute.

January - 2022

A zeolitic nanotube was realized through a combination of targeted synthesis and high definition structure elucidation. The atomic structure of the nanotube was determined using aberration-corrected STEM imaging and is published in the latest issue of Science together with the groups of Prof. Nair and Prof. Jones at GeorgiaTech.

September - 2021

Happy to contribute to this study on how large-scale simulations can be used to understand chemical synthesis. Nearly a million individual simulations were used to quantify how different templating molecules drive the selectivity in zeolite synthesis. This project together with Dr. Gomez-Bombarelli, MIT, and Dr. Moliner, ITQ, was published in Science.
