Lignin based fluorescent materials

Systematic study of the nature of lignin fluorescence mechanisms is still lacking, i.e., the relationship between lignin’s chemical structure/supermolecular structure and fluorescence properties including emission peaks/intensity, wavelength, and lifetime. Rare work is on modulation of lignin’s fluorescence properties through chemical structure modification. Lignin-based fluorescence materials design and application need further exploration.

PHAntastic

PHA-based iNnovative agriculTurAl Solutions to deliver bio-based ferTIlisers and plant protection produCts. Agrochemicals have doubled crop yields but have also caused negative impacts. The EU aims to reduce fertiliser losses and pesticide use by 50 % by 2030. Polymer-based delivery systems can help, but they generate plastic pollution. Agricultural plastics like mulch films and growth foams

TreeGlue: fully wood-based adhesives for sustainable wood composite

This project aims to develop high-performance bio-based adhesives from lignin, a renewable and abundant biomass resource. The research focuses on developing a green and mild demethylation strategy to convert methoxy groups in lignin into phenolic hydroxyl groups. This modification is expected to significantly enhance the reactivity of lignin, thereby promoting crosslinking reactions and leading to

Development and Characterization of High-Solid Cellulose Fiber Foams

This project focuses on developing bio-based porous foams from cellulose fibers at relatively high fiber concentrations. The aim is to improve fiber dispersion stability and structural homogeneity by using cellulose nanofibrils (CNF) as a stabilizing component.The project will investigate how fiber concentration and CNF content affect the final foam structure, including porosity, shrinkage, density variations,

Enzymatic functionalization of hemicellulose to produce biobased cross-linkers

The overall aim of this project is to enzymatically modify glycans from hemicellulose to produce bio-based cross-linkers for applications in adhesives, hydrogels and other cross-linked materials. Many materials that we consider as bio-based such as wood fibreboards, hydrogels and stabilizers from non-fossil polymers are still dependent on cross-linkers that are of fossil origin and often

Elucidating the mechanisms affecting diffusion of retention aid in flocculated fibre suspensions

The project is about the development of new knowledge regarding the transport of chemical retention aids and fines in flocculated pulp suspensions. Specifically, we have developed a method to study the diffusion of polyelectrolytes in model fiber flocs and to quantify the transport on the micrometre to millimetre scale.
