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 ... -
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) ... -
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 ... -
Development and characterization of thin printed films for gas sensing applications
(Åbo Akademi - Åbo Akademi University, 28.08.2015)The monitoring and control of hydrogen sulfide (H2S) level is of great interest for a wide range of application areas including food quality control, defense and antiterrorist applications and air quality monitoring e.g. ... -
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 ... -

Liquid transportation and distribution during (re)wetting : impact on coated papers in printing
(Åbo Akademi - Åbo Akademi University, 25.01.2013)In many industrial applications, such as the printing and coatings industry, wetting of porous materials by liquids includes not only imbibition and permeation into the bulk but also surface spreading and evaporation. By ... -
Molecular modeling of asymmetric induction in heterogeneously catalyzed hydrogenation of the C=O bond
(Åbo Akademi - Åbo Akademi University, 29.10.2010)Modifiering av metallytor med starkt adsorberade kirala organiska molekyler är eventuellt den mest relevanta teknik man vet i dag för att skapa kirala ytor. Den kan utnyttjas i katalytisk produktion av enantiomeriskt rena ... -
Nanostructured polymeric surfaces for biological interfaces
(Åbo Akademi University, 26.11.2021)In order to manufacture novel synthetic materials for use in biological applications, the continuous interactions over the materials interface must be thoroughly understood. It is difficult to develop all-encompassing ... -
Oxidation rates of carbon and nitrogen in char residues from solid fuels
Report / Åbo Akademi, Process Chemistry Centre : 13-01 (Åbo Akademi University, Process Chemistry Centre, 07.06.2013)Computational fluid dynamics (CFD) modeling is an important tool in designing new combustion systems. By using CFD modeling, entire combustion systems can be modeled and the emissions and the performance can be predicted. ... -
Pristine iota-Carrageenan and Chemically Functionalized Guar gum Polysaccharides for Metal-ion Complexation and CuS-based Nanocomposite Preparation
(Åbo Akademi - Åbo Akademi University, 19.04.2023)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 ... -
Protein adsorption and cell adhesion to nanostructured paper coatings
(Åbo Akademi - Åbo Akademi University, 16.12.2016)Protein coatings can be prepared in order to take advantage of their biological functions such as specific binding properties and the ability to enhance or reduce cellular adhesion. The physicochemical surface properties ... -
Utilizing κ-carrageenan Hydrogels in Teaching, Outreach and Chemical Gardens
(Åbo Akademi - Åbo Akademi University, 04.08.2023)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 ...
