Synthesis of sugar-based polymerizable materials for hydrogel preparation
(2022)
To match the growing need for biodegradable, biocompatible and biobased materials, this thesis explored the possibilities of the synthesis of bio-based (photo)polymerizable materials from sugars and sugar alcohols and the ...
Towards a Versatile and Sustainable Platform for Tailor-Made Adhesives
(Åbo Akademi - Åbo Akademi University, 2022-06-17)
The main objective of the present thesis work was to explore the possibility to design and synthesize versatile environmental-friendly adhesives and to adjust their properties to be suitable for different purposes by ...
Tuning strategies for control of integrating systems with model predictive control
(2022)
The objective of this thesis was to verify the suitability of Valmet’s own MPC solution, DNAMPC2, when applied to a common system encountered in process industry and biofuels processing. An extensive literature study was ...
Investigation of possible treatment methods for mitigating NOx and ammonia emissions
(2022)
The regulations on how much different components can be emitted into the air tighten all the time. Factories need to consider the emissions and the environmental impact that the processes are causing. Moreover, recycling ...
Development of structured catalyst and reactor technologies for biomass conversion - Continuous production of sugar alcohols
(Åbo Akademi University, 2021-05-19)
Energy-efficient technologies have been an aspiration for chemical industries, especially the design of chemical reactors. Structured catalysts play an important role to achieve this purpose. Several types of structured ...
Hydrofobering av handark med ASA – Inverkan av stabiliseringsmedel i olika mäldtyper
(2022)
Genom hela papprets historia har modifiering av papprets egenskaper varit av intresse. Ett sätt att modifiera egenskaperna är genom användning av olika tillsatsämnen. Exempelvis genom att tillsätta hydrofoberingsmedel som ...
Carbon dioxide capture from humid exhaust air and flue gases
(2022)
Carbon capture and storage (CCS), as well as utilisation of carbon dioxide (CO2), has become an increasingly important research area in order to achieve the goals set by the European Commission for the EU to become climate ...
Capillary Viscosity Analysis of Paper Coating Colors in a Paper Mill
(2022)
The capillary viscosity behavior of several coating colors used in a paper mill were analyzed with the ACA-AX100 capillary viscometer. The repeatability of the capillary viscometer was determined. The impact of the temperature ...
Hydrogen reduction of iron oxides : Experimental study
(2022)
Steel is one of the modern world’s core pillars in engineering and construction materials, but the steel production causes large carbon dioxide emissions. The steel industry needs to reduce its carbon emissions to prevent ...
Thin-layer composite reference electrodes
(Åbo Akademi, 2020)
In this thesis work the performance and feasibility of a thin layer polymer:salt composite reference electrode was assessed, in an attempt to further miniaturize the all solid-state reference electrode previously made. The ...
