2. 1. Effect of Wood Constituents Oxidation of Unsaturated Fatty Acids

   Author : Alireza Salehi Movahed; Mats K.G. Johansson; Mats Johnssson; Karin Jacobsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wood constituents; oil; oxidation; unstatured fatty acids; lignin; model lignin compounds; Polymer chemistry; Polymerkemi;

   Abstract : This work presents the mechanisms of free radicals in a model system between fatty acids oxidation process and wood components. The aim is to create a better understanding of new environmentally friendly materials for exterior wood protection. READ MORE

4. 2. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

   Author : Johan Reimer; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

   Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE

5. 3. Conversion of Biomass to Renewable Liquid Feedstocks in Pyrolysis-based Applications

   Author : Henry Persson; Weihong Yang; Louise Olsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Biomass; Pre-treatment; Stepwise Pyrolysis; Catalytic Pyrolysis; Pyrolys; Biomassa; Förbehandling; Stegvis Pyrolys; Katalytisk Pyrolys; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : The production of chemicals and fuels currently rely on fossil resources which are associated with global warming as well as economic and political instabilities. The demand for renewable alternatives is increasing as legislations on greenhouse gas emissions are becoming more stringent. READ MORE

6. 4. Good Guys : A Cultural Semiotic Study of the Print Advertising of the Oil Industry (1900-2000)

   Author : Pamela Vang; Jan Anward; Angelika Linke; Heidrun Kämper; Linköpings universitet; []
   Keywords : Oil industry; brand; print advertisements; communication; cultural semiotics; dialogism; myth; rhetoric; 20th century; Oljeindustrin; branding; tryckta annonser; kommunikation; kultursemiotik; dialogism; myt; retorik; 1900-talet;

   Abstract : Oil is central to our lives and is the source of many of the conveniences that we take for granted. It can bring wealth and prosperity to individuals and to nations, but is also a source of political conflict and the consequences of its impact on the environment are only now beginning to be fully recognised.

7. 5. Lecithin-Based Microemulsions for Pharmaceutical use - Phase behavior and Solution Structure

   Author : Christian von Corswant; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; felodipine; solubilization; drug delivery; self-diffusion NMR; alkylmaltoside; microstructure; isopropyl myristate; triglyceride; soybean phosphatidylcholine; Microemulsion; lecithin; Livsmedelsteknik;

   Abstract : Microemulsions are thermodynamically stable, transparent solutions of water, oil and amphiphile(s). It is possible to incorporate large amounts of oil in microemulsions, which makes them interesting for use as a drug delivery vehicle for water insoluble drugs. A prerequisite for pharmaceutical use, however, is a low toxicity of the composition. READ MORE
