Design and evaluation of nanoparticle-based delivery systems : towards cancer theranostics
(Åbo Akademi - Åbo Akademi University, 2017-04-21)
The design, characterization and applicability of nanoparticle (NP)-based delivery systems intended for cancer theranostics, are presented in this thesis. Mesoporous silica nanoparticles (MSNs) have been widely established ...
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 ...
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 ...

(Åbo Akademi - Åbo Akademi University, 2017-11-20)
There is an urgency for finding renewable resources for the replacement of fossil resources aiming at more environmentally friendly processing. The old concept of processing forestry biomass for pulp and paper that dominated ...
Fibre surface engineering using polysaccharide derivatives
(Åbo Akademi - Åbo Akademi University, 2017-12-12)
In the search for new materials and innovative solutions, pulp fibres obtained from wood chips have gained attention during the last few decades because they can be converted into a wide variety of pulp-derived products. ...
Hybridization of pulp fibres with LDH for applications in composites and lightweight fibrous foam
(Åbo Akademi - Åbo Akademi University, 2017-08-11)
The research around the pulp and paper (P&P) sector has changed dramatically during the past 15 years. P&P industry is particularly keen to find new solutions for the raw-materials they provide as well as explore novel ...
Engineering of novel cellulose-based biocomposites and biofoams
(Åbo Akademi - Åbo Akademi University, 2017-12-15)
Biomass is a renewable feedstock for producing fine chemicals, polymers, energy, and a variety of commodities. Transformation of biomass into diverse valuable products is the key concept of a bioeconomy. Chemical and ...
