2. 1. Multifunctional Supramolecular Organic Ferroelectrics

   Author : Indre Urbanaviciute; Martijn Kemerink; Mats Fahlman; Bengt-Harald Jonsson; Van Dijken Sebastiaan; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Ferroelectric materials are known and valued for their multifunctionality arising from the possibility to perturb the remnant ferroelectric polarization by electric field, temperature and/or mechanical stimuli. While inorganic ferroelectrics dominate the current market, their organic counterparts may provide highly desired properties like eco-friendliness, easy processability and flexibility, concomitantly opening unique opportunities to combine multiple functionalities into a single compound that facilitates unprecedented device concepts and designs.

4. 2. Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties

   Author : Anna Lutz; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas to particle conversion; volatility; secondary organic aerosols; FIGAERO; CIMS; monoterpenes; isoprene; SOA; BVOC;

   Abstract : Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the atmosphere are of secondary origin, formed as a result of gas to particle conversion. READ MORE

5. 3. Physical properties and processes of secondary organic aerosol and its constituents

   Author : Kent Salo; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

   Abstract : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. READ MORE

6. 4. New methods for determination of airborne pollutants : Focus on tetrabromobisphenol A, organophosphate triesters and polycyclic aromatic hydrocarbons

   Author : Johanna Tollbäck; Ulrika Nilsson; Peter Haglund; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air sampling; sampling methods; indoor air; SPE; SPME; extraction; dynamic extraction; online coupling; SWE; subcritical water extraction; GC MS; LC MS; organophosphate triesters; PAH; tetrabromobisphenol A; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Abstract : The work presented in this thesis concerns the development and evaluation of new methods of sampling and analysis of organic pollutants in the indoor and outdoor environment. In Paper I, the development of a new method was reported for the determination of the brominated flame retardant tetrabromobisphenol A (TBBPA) in air using sampling with glass fiber filter and polyurethane foam (PUF), ultrasonic solvent extraction and liquid chromatography coupled to electrospray ionisation mass spectrometry (LC-ESI/MS).

7. 5. Phenols, anisoles and fatty acids causing odour problems in drinking water

   Author : Susanne Karlsson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Taste and odour problems are the major causes of consumer complaints regarding drinking water in the industrialised world. Nevertheless, as yet there are no mandatory requirements to identify the compounds that are responsible for the observed off-flavour. READ MORE
