Catalytic functionalization of lignin

In this project we functionalize lignin using catalysts to form functional materials suitable for crosslinking to thermosets and/or composite materials.

Resource-efficient and non-toxic material flows from wood waste

With increasing focus on recycling, wood waste can increase its potential to generate secondary raw materials instead of incineration and landfilling. The quality of wood waste, as determined by the presence of material and mainly chemical impurities, is essential to ensure a high quality, clean and safe recycling loop for particleboards or for other emerging …

Functional lignin nanomaterials

This is a umbrella theme of research carried out in Sustainable Materials Chemistry (SUSMATCHEM) research group in Stockholm University. We aim to make most out of lignin with minimal processing and chemical modification according to the principles of green chemistry. In addition to fundamental studies of structure and properties of lignin and lignin nanoparticles, we …

A new sustainable route to polysaccharide hydrogel formation for medical and cosmetic applications

Hydrogels are an extremely versatile class of material, and have found relevance in cosmetic, medical, pharmaceutical, and industrial processes. A hydrogel has a low solid content, often comprising at least 90% water. Although hydrogels are increasingly used in cosmetics and drug manufacture, the production process is far from sustainable, relying on fossil-based polymers and chemical …

Smuts, olje- och vattenavvisande träytor

Detta är ett Formasfinansierat projekt 2018-2022 som har en doktorand vid KTH i samarbete med RISE och nu med Karlstads universitet. Doktoranden Haiyan Yin licade i november 2020 och fortsätter till doktor. Hon har publicerat två arbeten hittills, ett i Materials and Design och ett i Holzforschung.

Renewable High-Performance Materials from the Forest with Designed Degradation – Next Generation of Plastic (Re-Design Plastic)

Sustainable material design can alleviate the environmental burden related to material waste. Use of available and abundant resources, create materials that can be recycled, and final degradability in nature is central to achieve this. The overarching aim of the proposal is to holistically design new materials from cellulose fibers by; developing new sustainable modification strategies, …

Novel use of native cellulose in dispersions and functional biocomposites

This project supported by the FORMAS and Interreg Sverige-Norge specifically focuses on design and preparation of cellulose-based nanocomposites with added functionalities such as e.g. barrier, antimicrobial, catalytic and electronic properties, starting from water-based solutions of wood cellulose.

Expandable cellulose-based capsules

The development of expandable capsules holds a great promise for various advanced engineering applications. Preparation of such materials using renewable and sustainable resources is particularly attractive, where the development is driven by an increased global interest in new generations of green products that can meet the demands of the modern society. The aim of this …

Study of the multiscale networks of hemicellulose hydrogels by scattering techniques

The aim of the project is to develop multifunctional soft materials (hydrogels) from hemicelluloses for biomedical and food applications. We combine chemo-enzymatic methods to modify the molecular structure of the hemicelluloses and to tailor their assembly and rheological properties. In this project we want to understand the assembly mechanisms that drive the gel formation upon …

Xylem development and wood formation

The project focuses on lignification and cell death of xylem elements and how these processes influence the chemical and physical properties of the secondary cell walls and woody tissues of vascular plants. We use two model systems. The roots and hypocotyls of Arabidopsis thaliana provide excellent models for understanding the molecular and genetic control of …

Biomassa från Salix för en biobaserad ekonomi

Målet med projektet är att studera alternativa användningsområden av biomassa från salix, t.ex. som råvara för produktion av biobränslen och av nya biokemikalier. Salix är en snabbväxande gröda med hög biomassaproduktion. För att förstå möjligheten att använda salix som råvara i olika processer behöver vi studera hela odlingssystemet hos salix inklusive både ovan- och underjordsprocesser. …
