Reactive dissolution of sedimentary rocks in flue gas desulfurization : modeling and experimental investigation
(Åbo Akademi - Åbo Akademi University, 2010-12-10)
Svavel förekommer i kol och olja och oxideras vid förbränning till svaveldioxid (SO2). Årligen utsläpps stora mängder svaveldioxid som åstadkommer sura regn, minskning av stratosfäriskt ozon och sjukdomar. Av dessa orsaker ...
Synthesis, characterization and application of polypyrrole/zeolite composites
(Åbo Akademi - Åbo Akademi University, 2017-06-02)
Hybrid materials consisting of microporous aluminosilicate zeolites and the conducting polymer polypyrrole (PPy) were synthesized and characterized. The PPy/zeolite composites exhibit both the mechanical and chemical ...
Utilization of steelmaking waste materials for production of calcium carbonate (CaCO3)
(Åbo Akademi - Åbo Akademi University, 2014-10-10)
The steel industry produces, besides steel, also solid mineral by-products or slags, while it emits large quantities of carbon dioxide (CO2). Slags consist of various silicates and oxides which are formed in chemical ...
The role of metal ions in selective and sustainable processes
(Åbo Akademi - Åbo Akademi University, 2015-10-14)
Sustainability and recycling are core values in today’s industrial operations. New materials, products and processes need to be designed in such a way as to consume fewer of the diminishing resources we have available ...
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 ...
Paper for printed electronics and functionality
(Åbo Akademi - Åbo Akademi University, 2013-10-04)
Mass-produced paper electronics (large area organic printed electronics on paper-based substrates, “throw-away electronics”) has the potential to introduce the use of flexible electronic applications in everyday life. While ...
Influence of plasma modification on surface properties and offset printability of coated paper
(Åbo Akademi - Åbo Akademi University, 2010-06-11)
The properties of the paper surface play a crucial role in ensuring suitable quality and runnability in various converting and finishing operations, such as printing. Plasma surface modification makes it possible to modify ...
Modification of commercial poly-lactide for extrusion coated food packaging applications
(Åbo Akademi - Åbo Akademi University, 2015-08-21)
Poly-L-lactide (PLLA) is a widely used sustainable and biodegradable alternative to replace synthetic non-degradable plastic materials in the packaging industry. Conversely, its processing properties are not always optimal, ...
Microscopic simulation of pigment coating consolidation
(Åbo Akademi - Åbo Akademi University, 2010-05-14)
The control of coating layer properties is becoming increasingly important as a result of an emerging demand for novel coated paper-based products and an increasing popularity of new coating application methods. The governing ...
Enhancing performance of paper coatings by tailor-made plastic pigments
(Åbo Akademi - Åbo Akademi University, 2011-07-01)
The paper industry is constantly looking for new ideas for improving paper products while competition and raw material prices are increasing. Many paper products are pigment coated. Coating layer is the top layer of paper, ...
