1. 1. In silico methods to prioritize chemicals with high exposure potential

   Författare :Efstathios Reppas Chrysovitsinos; Matthew MacLeod; Anna Sobek; Michael Matthies; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free energy relationship; solvation parameters; polymers; materials; partitioning; octanol; Arctic contaminants; AMAP; POPs; Stockholm Convention; vPvB; REACH; OECD; QSAR; planetary boundaries; persistence; bioaccumulation; long-range transport; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Chemicals offer a wide range of desired functions and are used in a variety of consumer goods and industrial sectors. The number of individual synthetic organic chemicals produced and the total global chemical production volume are increasing. LÄS MER

3. 2. Experimental Study of Using Butanol or Octanol Blends as Alternative Fuels in Diesel Engines

   Författare :Tankai Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the increased travel demand, the consumption of fossil fuels, as the main energy source for transportation, has risen sharply over the last few decades. Fossil fuels are considered a non-renewable resource. In addition, burning them in internal combustion engines can generate a large amount of greenhouse gas (GHG) emissions. LÄS MER

4. 3. Partitioning of Drugs and Lignin Precursor Models into Artificial Membranes

   Författare :Elisabet Boija; Gunnar Johansson; Per Lundahl; Christine Lagerquist Hägglund; Marja-Liisa Riekkola; Uppsala universitet; []
   Nyckelord :Biochemistry; Bilayer disk; Capillary electrophoresis; Detergent; Drug; Electrostatic interaction; Hydrophobic interaction; Immobilized liposome chromatography; Lignin; Lignin precursor model; Liposome; Membrane model; Octanol water partitioning; Partitioning; Phospholipid; Phospholipid bilayer; Sterol; Biokemi;

   Sammanfattning : The main aim of this thesis was to characterize membrane-solute interactions using artificial membranes in immobilized liposome chromatography or capillary electrophoresis. The partitioning of a solute into a cell membrane is an essential step in diffusion across the membrane. LÄS MER

5. 4. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines

   Författare :Tankai Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. LÄS MER

7. 5. Sample Preparation of Organic Compounds in Environmental Analysis using Liquid Membrane Extraction

   Författare :Luke Chimuka; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reverse phase liquid chromatography; octanol-water partition coefficients; phenolic compounds; s-triazines; supported-liquid membrane extraction; environmental analysis; UV detection; Analytical chemistry; Analytisk kemi;

   Sammanfattning : This thesis demonstrates the potential of the liquid membrane extraction technique as an alternative method for the analysis of trace ionisable organic compounds in the environment. Liquid membrane based extraction methods for the analysis of s-triazine herbicides and phenolic compounds were developed. LÄS MER
