TREESEARCH logotype 2 black
Treesearch NMR webinar series

NMR is one of the major spectroscopic techniques for studying  supramolecular organization on an atomic level and water-interactions of lignocellulosic materials.  With this webinar series, Treesearch aims to inspire and show what can be determined from NMR studies.

In a series of webinars, experts are sharing their knowledge on different aspects of NMR. The webinars are open for all to attend and links are found directly on this page.

CP/MAS 13C-NMR on isolated cellulose

Adj. Prof. Tomas Larsson, KTH / RISE

Tomas Larsson is well renowned for his work on structural understanding and how physical and chemical treatment affects cellulose fibrils and fibril aggregates in the fibre wall. He has a unique holistic perspective of the fibre that has grown from an in-depth knowledge on how to perform mathematical analysis of data generated from CP/MAS 13C-NMR, X-ray scattering, FSP and carbohydrate composition. In this webinar he will present on the use of solid-state NMR for studying the supramolecular structure of cellulose.

In 2017 PT Larsson was awarded SPCIs Ekman medallion for his work on cellulose

Want to learn more about NMR? Treesearch will advertise two Research Infrastructure courses 2024:
The first course is on the fundamentals and small molecule characterization and assignment. The course will be held Spring 2024.
The second course is on advanced NMR, will focus on characterization and assignment of larger complex lignocelulosic molecules/polymers, physical phenomena such as water dynamics and interaction with cellulose and determination of bond rotation and crystalline-amorphous ratios. The course will be held Autumn 2024.
