Fractionation of wood components using membrane filtration

Development of efficient separation processes are vital for the realisation of the biorefinery concept. Membrane filtration as a pressure driven operation has the potential of being a very energy efficient separation and fractionation method in this application. However one of the largest challenge when using membranes is fouling and these fouling problems can be expected […]

Fibre-based materials for next generation energy storage systems

Anastasia Riazanova

In this project we will explore the possibilities given by fibre-based wood polymer materials for applications for high capacity batteries, for electromobility as well as grid energy storage. These materials offer routes for modification and tuning of chemistry, the morphology and processing to obtain e.g. tailored porosity and functionality. This tailoring is needed both on

High barriers for wood-based materials

Anastasia Riazanova

Nature-inspired high barrier materials from wood components for wood-based materials. Objectives Scientific: Investigate how the different components in a fruit/plant cuticle contribute to very high barrier properties (wax/lipid, crosslinked polyester and polysaccharides). Why are they assembled together the whey they are? Are there synergy effects? Can we go even beyond Natures high barriers by introducing

Conductor patterns in wood and paper

Anastasia Riazanova

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

Investigation of membrane fouling during microfiltration of wood components

Anastasia Riazanova

Development of efficient separation processes are crucial for the realisation of the biorefinery concept, which is important to enable the substitution of fossil raw materials for production of materials and chemicals. Membrane filtration as a pressure driven operation has the potential of being a very energy efficient separation method in this application. However one of

Structure and Properties of Hemicelluloses

Anastasia Riazanova

Hemicelluloses represent one of the largest natural resources on Earth. They occur together with cellulose in plant cell walls and the exact structure varies between different types of plants. However, generally they are heteropolysaccharides that are branched and often also acetylated and methylated. The biological background for the structural heterogeneity of hemicellulose is unclear. Hemicelluloses

Ultrafiltration of Lignin – Valorization

Anastasia Riazanova

The research is focused on fractionated kraft lignins and the potential use in different applications. Lignin as a second abundant biopolymer, is being produced in a large scale annually without any high value applications. It has a great structure, including aliphatic and aromatic groups with lots of active hydroxyl groups. One of the main obstacle
