Aerobic Oxidation of Arabinose – Glucose Mixtures over Gold Nanoparticles
(Åbo Akademi, 2020)
The fate of Sn, Pb, Cu, and Ni from e-waste in secondary copper smelting
(2023)
Electronic waste (e-waste) is waste generated from end-of-life electrical and electronic equipment. E-waste is the fastest growing type of solid waste stream. This has become a major environmental concern. Fortunately, the ...
Dealing with challenges in black liquor evaporation
(2023)
The main objective of this thesis is to identify problems in black liquor evaporation that affect the evaporation economy. Evaporation of black liquor is a necessary process step to increase the dry substance content of ...
Novel experimental setup for coulometric signal transduction in ion-selective electrodes
(2022)
In this research work, a simple and versatile novel experimental setup for coulometric signal transduction in ion-selective electrodes was introduced and studied. It is based on a constant potential coulometry measurement ...
Bipolar membrane electrodialysis of ammonium sulfate/bisulfate solutions : energy efficiency versus throughput optimization
(2023)
To combat carbon emissions, carbon capture and storage becomes an increasingly urgent topic. The most common way of carbon dioxide capture and storage is geological storage in, for example, depleted oil or gas reservoirs. ...
Optimization of Lime Injection in EAF Systems by Using Pneumatic Sidewall Injectors
(2023)
This master’s thesis work is a project for Nordkalk corporation as a part of a Business Finland co-funded project on Fossil-Free Steelmaking (FFS). The experiments of this study were performed in the Laboratory of Process ...
