Flexible pigment-cellulose nanofibril composites for printed electronics applications
(VTT Technical Research Centre of Finland Ltd, 2017-10-27)
The aim of this work was to expand the possibilities of novel use of cellulose micro- and nanofibrils (CMNF) for bio-based composites. The new approach in this work was to combine inorganic pigments and CMNF in a relatively ...
Heterogeneous catalytic copolymerization reactions of carbon dioxide and propylene oxide over polyalcohols under subcritical conditions
(Åbo Akademi University and Universidad de Valladolid, Spain, 2017-03-15)
Carbon dioxide (CO2) is one of the main gases which cause the greenhouse effect. As a way to attenuate this damage, CO2 could be used as a building block for copolymerization reactions; precisely as C1 feedstock (monomer ...
Oral pressure and flow feedback components in semi-occluded vocal tract exercises
(Åbo Akademi - Åbo Akademi University, 2017-09-08)
Vocal training with a semi-occluded vocal tract has been used for a long period of time. One way to obtain a semi-occlusion is by phonating through a straw or tube while keeping the free end of the tube in air or submerged ...
Studies on Ceramide/Colipid Interactions in Complex Bilayers
(Åbo Akademi - Åbo Akademi University, 2017-12-01)
Ceramide belongs to an important class of sphingolipids and it constitutes the hydrophobic backbone of all complex sphingolipids. Ceramide plays an important role in different biological processes such as cell signaling, ...

Patterns in diversity and function of benthic fauna in a coastal system under environmental change
(Åbo Akademi - Åbo Akademi University, 2017-03-10)
Increasing changes in environmental conditions are reshaping marine ecosystems and their communities on a global scale. Coastal areas are particularly vulnerable as environmental stressors have a stronger impact due to the ...
Spatial distributions of phytoplankton in rock pools : metacommunities to molecules
(Åbo Akademi - Åbo Akademi University, 2017-04-28)
Ecological studies on how populations and communities assemble and function traditionally focussed on the effects of local environmental conditions and species interactions. Still, no species, the consequences of its actions ...
Phosphorus in the sediments of the northern Baltic Sea archipelagos : internal P loading and Its impact on eutrophication
(Åbo Akademi - Åbo Akademi University, 2017-03-31)
In the 20th century Eutrophication as a result of anthropogenic enrichment of nutrients has become a global problem in marine coastal waters. In the Baltic Sea, eutrophication is considered the most severe environmental ...
Ocean acidification in the Baltic Sea : implications for the bivalve Macoma balthica
(Åbo Akademi - Åbo Akademi University, 2017-04-12)
The Baltic Sea is one of the most human-impacted sea areas in the world and its ecosystems are exposed to a variety of stressors of anthropogenic origin. Large changes in the environmental conditions, species and communities ...
Copepods in a changing sea : ocean acidification, long-term changes and short-term variability
(Åbo Akademi - Åbo Akademi University, 2017-05-19)
The rapid increase in atmospheric carbon dioxide is causing global warming but also changes in the ocean chemistry. When carbon dioxide dissolves in seawater it changes the carbonate chemistry towards lower levels of ...
