The role of metal ions in selective and sustainable processes
(Åbo Akademi - Åbo Akademi University, 14.10.2015)Sustainability and recycling are core values in today’s industrial operations. New materials, products and processes need to be designed in such a way as to consume fewer of the diminishing resources we have available ... -
The utilization of participating gases and long-wave thermal radiation in a passive cooling skylight
(Åbo Akademi - Åbo Akademi University, 11.11.2016)The motivation for this thesis was to study how the greenhouse effect, which controls the temperature of our planet, could be put to use for future energy needs. The main objective of this work was to identify and quantify ... -
Thermal reactions of the major hydrocarbon components of biomass gasification gas
(Åbo Akademi - Åbo Akademi University, 19.12.2014)Gasification of biomass is an efficient method process to produce liquid fuels, heat and electricity. It is interesting especially for the Nordic countries, where raw material for the processes is readily available. The ... -
Thermochemical Conversion Characteristics of Vinasse
(Åbo Akademi - Åbo Akademi University, 28.08.2020)Vinasse, also known as stillage or spent wash, is an effluent from the distillery plant of the integrated sugar-ethanol process. It is characterized by an acidic pH, a black-reddish color, and being a dilute effluent with ... -
Three-dimensional printing of wood-derived biopolymers towards biomedical applications
(Åbo Akademi - Åbo Akademi University, 22.02.2019)Three-dimensional (3D) printing has shown promising potential in fabrication of complex tissue with a structural control from micro- to macro-scale, meeting the requirements of tissue engineering. Wood-derived biopolymers ... -
Topochemistry of physical and chemical pretreatments of biomass as investigated by FE-SEM, XPS and ToF-SIMS
(Åbo Akademi - Åbo Akademi University, 28.05.2014)Surface chemistry is of great importance in plant biomass engineering and applications. The surface chemical composition of biomass which includes lignin, carbohydrates and extractives influences its interactions with ... -
