Ex situ and in situ advanced electron microscopy of enzymatic action for biomass tailoring and transport paths in conducting fibres and yarns
The structure of wood is complex with many components. As new cellulose-based materials and devices are to be developed and optimized it is crucial to understand the material microstructure of wood and also the properties of its individual microstructural constituents. Electron microscopy offers a unique capability for site specific imaging, diffraction and spectroscopy with high […]
Polysaccharide Monooxygenases (LPMOs) for Advanced Nanocellulose Materials
LPMOs (lytic polysaccharide monooxygenases) are oxidative enzymes that enhance cellulose fibrillation by introducing charged carboxyl groups onto the cellulose surfaces in aqueous reaction conditions. The use of LPMOs in production of nanocelluloses could reduce the need of hazardous chemicals and facilitate more environmentally friendly processes. The aim of this subproject is to produce recombinant LPMOs […]
Hållbara isoleringsmaterial för efterisolering av byggnader
Projektets huvudsakliga syfte är att utveckla teknik som kan bidra till att förbättra energieffektiviteten i de stora hyreshus som byggdes på 1960- och 1970-talet och bidra till att uppnå detta på ett hållbart sätt. Ambitionen är att utveckla ett isoleringsmaterial som är 100% biobaserat och återvinningsbart via kartongåtervinningen och därmed bidra till omställningen till en […]
Assessment of the homogeneity of chemical modifications aimed for thermoplasticisation of cellulosic fibres
The strong driving force behind the sustainable biomaterial-based society is to replace the fossil fuel-based materials with renewable resources to for example address the climate change. Thermoplastic polymer products are used on a daily bases in every household and they need to possess the properties such as being ductile and formable. However, cellulosic materials do […]
Bio-based binders for molded cellulose fibers
Natural binders are inexpensive, biodegradable, environmentally friendly and renewable, but usually form weaker bonds and slightly harder to apply. The objective of the project is to develop and optimize the process of using various plant polysaccharides as binder for holocellulose fibers and cellulose nanofibrils (CNF). The selected polysaccharides are further functionalized to improve interfacial adhesion […]
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 […]
Cross-linked protein-carbohydrate hydrogels
Using newly discovered carbohydrate-binding proteins, we are developing a novel method for hydrogel formation via biopolymer cross-linking.
Wood cell walls on the nano level
The aim of the project is to obtain information about the nanoscale distribution of the constituents in wood cell walls, such as cellulose, hemicellulose, and lignin. To reach our aim we will use a novel infrared microscopy technique (nano FTIR microscopy) with the unique ability to provide chemical information with a spatial resolution of 20 […]
Self-assembly of 2D nanoflakes by using 1D cellulose nanofibrils
The earth-abundant 1D cellulose nanofibrils (CNFs) have shown the capacity to assemble different functional nanoparticles into 2D films and 3D foams. 2D nanomaterials such as MXene, graphene, transitional metal dichalcogenides (MoS2, WS2, etc.) are the ones of most promising functional materials in optical, electronic, and magnetic fields. We are using the 1D CNF to align […]
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.
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 […]
Development of biobased and recyclable composite materials
We aim to develop new renewable and recyclable materials generated from bioderived sources. Our particular interest is directed towards development of composite materials based on nanofibrilated cellulose and epoxy thermosets.
