Utilizing κ-carrageenan Hydrogels in Teaching, Outreach and Chemical Gardens
(Åbo Akademi - Åbo Akademi University, 2023-08-04)
κ-carrageenan is a biopolymer that can be extracted from red seaweeds and has found great use for example in the food industry due to its excellent gelling, thickening and stabilizing abilities. The work done in this thesis ...
Pristine iota-Carrageenan and Chemically Functionalized Guar gum Polysaccharides for Metal-ion Complexation and CuS-based Nanocomposite Preparation
(Åbo Akademi - Åbo Akademi University, 2023-04-19)
Natural polysaccharides are ubiquitous in nature and have been widely used in human history as food, materials, fuels, and medicine. To cope with climate crisis and develop a more sustainable economy, promoting the use of ...
Laboratory Studies on Aqueous Absorption and High Temperature Chemistry of NOx and SOx in Thermal Conversion of Biomass Waste
(Åbo Akademi - Åbo Akademi University, 2023-05-05)
In order to fulfill the transition to a climate neutral economy and society, various renewable energy sources are needed to replace fossil fuels. Thermal conversion of biomass waste streams plays an important role in this ...
Thermochemical Conversion Characteristics of Vinasse
(Åbo Akademi - Åbo Akademi University, 2020-08-28)
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 ...
Hierarchically Porous Silica, Carbon and Metal Oxide Monoliths – Synthesis and Characterization
(Åbo Akadem - Åbo Akademi University, 2006)
Silica monoliths exhibiting a three-modal, hierarchical pore structure have successfully been prepared via sol-gel processing. Monolithic bodies with interconnected macropores in the μm range are a result of phase separation ...
Application of LC-MS for the identification and quantification of pharmaceuticals and their transformation products during catalytic ozonation
(Åbo Akademi University, 2021-02-19)
The presence of pharmaceuticals in the environment is of concern due to their harmful effect on aquatic organisms. Because of this, it is important that they are effectively removed in wastewater treatment plants. Conventional ...
Printed platforms for paper-based analytical applications
(Åbo Akademi - Åbo Akademi University, 2014-10-17)
Paper-based analytical technologies enable quantitative and rapid analysis of analytes from various application areas including healthcare, environmental monitoring and food safety. Because paper is a planar, flexible and ...
Corrosion behaviour of boiler tube materials during combustion of fuels containing Zn and Pb
(Åbo Akademi University, Process Chemistry Centre, 2012-06-16)
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 ...
Ion selective electrodes for determination of low and ultra low concentrations of lead (II) in natural waters
(Åbo Akademi - Åbo Akademi University, 2012-06-14)
Monitoring natural waters for toxic components is essential for human well-being. Since
the content of pollutants occurring in natural ecosystems should be kept as low as
possible, there is an ongoing search for analytical ...
Computational chemistry studies of wood-derived lignans
(Åbo Akademi - Åbo Akademi University, 2013-05-31)
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) ...
