Enzyme-mediator coupling for non-invasive glucose monitoring
(2023)The aim of this work was to modify the enzymes glucose oxidase (GOx) and glucose dehydrogenase (GDH) with electron relays for wearable glucose biosensor applications. The significance of glucose biosensors lies in their ... -
Estimation applied to Selective Catalytic Reduction
(2023)Global warming and climate change are phenomena that have resulted in stricter legislation for combustion emissions. Fossil fuels and combustion engines remain a vital energy source for the years to come, especially for ... -
Evaluation of Optimal Chemical Aids and Process Parameters in Oil Refinery Wastewater Flocculation and Flotation
(Åbo Akademi, 2019)Wastewater treatment of oil refinery effluents is a pre-requisite for refinery operations in a continuously stricter environmental regulatory framework. One effective method of treating typical refinery wastewaters with ... -
Fat Fractionation by Distillation
(Åbo Akademi, 2020)The demand for renewable fuels and chemicals is growing, but at the same time, discussion about the use of edible raw materials in the production has intensified. Waste-based fats and oils are cheaper and their consumption ...Sekretessbelagd fram till 3.3.2024 -

Flash Drying of Recycled Paper Pulp in a Mechanically Agitated Fluidized Bed
(Åbo Akademi, 2020)Flash drying of pulp is an interesting option for drying of market pulp, mainly due to its high thermal efficiency and relatively low operating and capital costs. Typical flash dryers consist of a series of high drying ...Sekretessbelagd fram till 1.6.2024 -
Fluidized bed agglomeration inhibition by additives during combustion of demanding biomass fuels
(2022)Bed agglomeration is a problem related to fluidized bed combustion. It is a result of bed particles and/or fuel ash gluing together, forming agglomerates, i.e., large clusters. These agglomerates can, over time, increase ... -
Fractionation and Characterisation of Enzymatic Hydrolysis Lignin
(2022)Lignin is one of the major components in lignocellulosic biomass and the most abundant aromatic building block in nature. Technical lignins extracted from either pulping or biorefining processes provide a variety of complex ... -
Framework for strategising in business ecosystems
(Åbo Akademi, 2020)Business ecosystems have been studied for almost 30 years, having its origin in Moore’s theories that he developed in the early 1990’s. A business ecosystem is a organisational structure of companies, customers, governmental ... -
Framställning av högbarriärpapper med reversgravyr
