Chemical derivatization of galactoglucomannan for functional materials
(Åbo Akademi - Åbo Akademi University, 14.11.2014)In the framework of the biorefinery concept researchers aspire to optimize the utilization of plant materials, such as agricultural wastes and wood. For most of the known processes, the first steps in the valorisation of ... -
Formic acid fractionation of bamboo and valorization of isolated lignin
(Åbo Akademi - Åbo Akademi University, 14.02.2020)Lignocellulosic biomass is the most abundant and renewable natural resource on earth. It has been regarded as an environmentally sustainable raw material to be converted into chemicals and biomaterials. To profitably use ... -
Functionalisation of spruce O-acetyl-galactoglucomannans for barrier and composite applications
(Åbo Akademi - Åbo Akademi University, 23.10.2015)The increasing use of energy, food, and materials by the growing population in the world is leading to the situation where alternative solutions from renewable carbon resources are sought after. The growing use of plastics ... -
Improvement of wet and dry web properties in papermaking by controlling water and fiber quality
(Åbo Akademi - Åbo Akademi University, 08.11.2013) -
Intensification of hemicellulose hot-water extraction from spruce wood by parameter tuning
(Åbo Akademi - Åbo Akademi University, 22.05.2015)The growing population on earth along with diminishing fossil deposits and the climate change debate calls out for a better utilization of renewable, bio-based materials. In a biorefinery perspective, the renewable biomass ... -
Multifaceted Applications of Nanocellulose-based Materials for Water Remediation
(Åbo Akademi - Åbo Akademi University, 26.08.2022)During the last decades, water pollution has become a severe environmental and health crisis in many countries due to rapid industrialization and urbanization, attracting increasing attention worldwide. As one of the most ... -
Pressurized hot water flow-through extraction of birch wood
(Åbo Akademi - Åbo Akademi University, 13.03.2015)Effective processes to fractionate the main compounds in biomass, such as wood, are a prerequisite for an effective biorefinery. Water is environmentally friendly and widely used in industry, which makes it a potential ... -
Regioselective modification of galactose-containing polysaccharides in aqueous media
(Åbo Akademi - Åbo Akademi University, 25.10.2013)Biorefining is defined as sustainable conversion of biomass into marketable products and energy. Forests cover almost one third of earth’s land area, and account for approximately 40% of the total annual biomass production. ... -
Structure-Property Correlation on Solvent-Fractionated Lignin to Functional Materials
(Åbo Akademi - Åbo Akademi University, 22.09.2023)The abundance of lignin in combination with its impressive properties, i.e., a macromolecule with multifunctional groups, an amphiphilic molecular structure, and a unique nanotechnological advantage of forming nanospheres, ... -
Supramolecular design of cellulose-based hydrogel beads
(Åbo Akademi - Åbo Akademi University, 08.03.2019)The degree of polymerization (DP) of cellulose fibres is an important factor to consider during dissolution in water-based solvent system and to design further advanced biomaterials. The lower is the DP, the higher cellulose ... -
The pH-dependent phase distribution of wood pitch components in papermaking processes
(Åbo Akademi - Åbo Akademi University, 15.11.2013)Wood contains only a very small amount of lipophilic extractives, commonly known as wood pitch. The pitch is known to cause severe problems in papermaking processes. The amount of pitch in process waters can be decreased ... -
