H2O2 – Fuel and Energy Technology for the Future

Researching all-organic photo- and electro-catalysis to explore novel pathways to produce hydrogen peroxide, H2O2, and convert this fuel into electricity with a novel fuel cell technology. In order to achieve high-rate and large-volume production of H2O2 and conversion into electricity, we suggest to research and develop a novel catalytic paper electrode technology. These paper electrodes …

Controlling product characteristics on board machine utilization process data

Quality on any board and paper products is dependent on being able to maintain low variability within product characteristics. A common problem is that these characteristics are measured cannot be measured online in the production, and is the time resolution will therefor be very low. The product characteristics will be dependent on the process characteristics, where …

Forest-based materials for optoelectronic devices

We explore the use and development of forest-based materials in organic and hybrid organic optoelectronic devices. We carry out fundamental materials studies combined with device design, fabrication and characterization.

Low density and wet stable networks of cellulose nanofibrils with a tailored 3D shape for advanced applications

The project has the following purpose and aims: (a) Novel wet-stable, low density networks of cellulose nanofibrils (CNF) with a tailored 3D structure; (b) Tailored structures through controlled freeze-linking of the CNF followed by a formation of interpenetrated polymeric networks inside the cellulose network for controlled liquid spreading and liquid holding capacity; (c) Tailored 3D …

EPIC – elektro- och fotokatalys inducerat i papper

Den vanligaste metoden att framställa papper görs genom den så kallade Kraft-processen. I denna process tas olika komponenter bort från träet för att möjliggöra vidare framställning av högkvalitativ cellulosa och papper. En viktig del i Kraft-processen är den så kallade avlignifieringen. Under denna process öppnas cellulosaväggen och porer av storleken från 20 till 50 nanometer …

Composite of lignin derivatives and conducting polymers for electro-capturing of toxic heavy metals

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 …

Lignosulfonate composited with electronic polymers for large scale energy storage applications

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, …

Porous, optical and IR-absorbing cellulose for solar evaporators

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 …

Soft cellulose-based robotics

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.
