Wow.

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.

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.

Tom Willhammar has been appointed Docent in Materials Chemistry at the Science Faculty at Stockholm University.

We are starting a new project with funding from Formas - A Swedish research council for sustainable development. The project will be building new understanding of water remediation from contaminants of emerging concern using electron microscopy.

Pepto-Bismol has relieved upset stomachs for more than a century, but the structure of the active ingredient remained unknown. Using iDPC-STEM and 3D ED we were able to reveal its molecular structure.

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.

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.
