Characterisation of waste for combustion : with special reference to the role of zinc
Report / Åbo Akademi, Process Chemistry Centre : 13-04 (Åbo Akademi University, Process Chemistry Centre, 11.12.2013)Waste combustion has gone from being a volume reducing discarding-method to an energy recovery process for unwanted material that cannot be reused or recycled. Different fractions of waste are used as fuel today, such as; ... -
Chemical changes in biomass during torrefaction
Åbo Akademi, Faculty of Science and Engineering, Johan Gadolin Process Chemistry Centre : 16-01 (Åbo Akademi University, Johan Gadolin Process Chemistry Centre, 22.01.2016)Torrefaction is moderate thermal treatment (~200-300 °C) of biomass in an inert atmosphere.

Chemical engineering of surface coatings for natural stones
(Åbo Akademi - Åbo Akademi University, 24.02.2017)Natural stones are materials widely used in today’s architecture. White stones (such as marble) and speckled stones (such as granite) are regarded as suitable for decorative purposes and as construction materials. A major ... -
Combustion properties of biomass residues rich in phosphorus
Report / Åbo Akademi, Process Chemistry Centre : 12-02 (Åbo Akademi University, Process Chemistry Centre, 04.04.2012)The currently-used sources of biomass are limited so new ones are required in order to meet the European Union target and to satisfy the constantly-increasing demand for energy. This is why energy recovery from residues ... -
Computational chemistry studies of wood-derived lignans
(Åbo Akademi - Åbo Akademi University, 31.05.2013)This thesis is based on computational chemistry studies on lignans, focusing on the naturally occurring lignan hydroxymatairesinol (HMR) (Papers I II) and on TADDOL-like conidendrin-based chiral 1,4-diol ligands (LIGNOLs) ... -
Corrosion behaviour of boiler tube materials during combustion of fuels containing Zn and Pb
Report / Åbo Akademi, Process Chemistry Centre : 12-03 (Åbo Akademi University, Process Chemistry Centre, 16.06.2012)Many power plants burning challenging fuels such as waste-derived fuels experience failures of the superheaters and/or increased waterwall corrosion due to aggressive fuel components already at low temperatures. To ... -
Coulometric Transduction Method for Solid-Contact Ion-Selective Electrodes
(Åbo Akademi University, 11.06.2021)As one of the pioneering works in the field of solid-contact ion-selective electrodes (SCISEs), a new coulometric transduction method was proposed by Bobacka’s group from Åbo Akademi University. This thesis work was carried ... -
Crystallization characteristics of bioactive glasses
Report / Åbo Akademi, Process Chemistry Centre : 08-07 (Åbo Akademi University, Process Chemistry Centre, 07.11.2008)Bioactive glasses are excellent candidates for implant materials, because they can form a chemical bond to bone or guide bone growth, depending on the glass composition. Some compositions have even shown soft tissue ... -
Development and application of plasmonic materials for dye- and polymer-sensitized solar cells
(Åbo Akademi - Åbo Akademi University, 18.05.2018)Among the numerous solar cell technologies, emerging thin film solar cells, such as dye-sensitized solar cells, offer the possibility for large-scale integration using sustainable and low-cost materials. In these thin ... -
