X-ray tomography is a powerful way of imaging the internal structures of materials, without having to apply advanced sectioning techniques. One limitation in X-ray tomography of soft matter (e.g. wood based materials, polymers) is the poor contrast between components, which is inherent due to low differences in electron density. This project aims to develop contrast […]

This research aims to develop and evaluate eco-friendly lignin-based nanoparticles derived from rice husk for dual applications in biodegradable films and sunscreen formulations. The project focuses on synthesizing spherical lignin nanoparticles (sLNPs) and hybrid lignin nanoparticle composites through green, sustainable methods. These nanomaterials will be thoroughly characterized using SEM, TEM, DLS, FTIR, UV-Vis, and TGA
Thermosets are known for their poor (re-)processing and recycling capabilities due to theirpermanently crosslinked microstructure. As a result, their end-of-life options are limited to landfill orincineration, preventing thermosetting materials from meeting the demand for sustainable andcircular materials. In recent years, the introduction of dynamic covalent bonds in polymeric networkshas formed a promising solution to the
Efficient insulating foams are crucial as building materials as they reduce the energy consumption for heating, but currently polymeric foams are predominantly made from fossil-based resources with linear waste streams making them unsustainable. In order to deal with these challenges, the goal with this project is to develop recyclable polymeric insulating foams that stem from

Aerogels are attractive in various applications ranging from aerospace to energy storage due to low density and high specific surface area. Mainstream strategy to obtain lignocellulosic aerogels is bottom-up approach, disintegrating wood into nano building blocks (e.g. nanocellulose) followed by reassembling into aerogels. The complex and/or energy intensive processing are challenges. Top-down approach is an

Cellulose nanofibrils (CNFs) are known to form associative structures even at very low concentrations; however, the fundamental mechanisms governing their assembly and the associated time scales remain poorly understood. Although significant research efforts are underway in this field, systematic, long-term investigations into the stability of CNF dispersions are still lacking. The aim of this project
