Among the 100% water on planet earth, less than 1% is liquid fresh water and about 0.0025% is available fresh water for drinking, food and industries. More than 90% of the fresh water is utilized for agriculture and industries. Pollution of water is thus an increasingly important problem. One of the most challenging depollution process […]
A renewable resource from existing forest industry is the black liquor that mainly goes to combustion. The dominating biopolymer in black liquor is a derivative of lignin. At LiU we have shown how lignin and lignosulfonate (LS) can be used to store charge into biopolymer electrodes, and built supercapacitors/supercabatteries of such electrodes. In these electrodes,
This project aims at investigating how conducting polymers interact with forest-based materials to form hierarchically nanostructured aerogels. We will develop protocols for fine tuning the structural and mechanical properties of cellulose-base conducting aerogels, and to control the penetration of solar absorbers (i.e. conducting polymers) in the nanostructured forest-based aerogels. We will study how energy is

The project is focused on the development of novel concepts for soft electromechanical actuators and robotics based on nanocellulose composites. Nanocellulose foams are light weight and compressible, making them ideal for functionalization for actuators. Magnetic and electronic functional composites will be developed and fabricated into novel device concepts. The project is part of WWSC.

In this project we perform multi-scale theoretical modelling of wood-based materials and devices ranging from the Molecular Dynamics and ab initio simulations on the atomistic level to the drift-diffusion device simulation on the system level to answer the fundamental questions concerning material structure, morphology, polymerization, porosity, ion diffusion, role of water, solvents and many others,

This project is part of WWSC 2.0 at LiU. The project aims at investigating methods to modify cellulose-based materials such as paper to become electrically conductive, and moreover to do so in a spatially constrained way, in order to create conductor patterns. The long-term goal of the project is deriving 3D patterning and manufacturing techniques
