1. 6. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

   Författare :Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. LÄS MER

3. 7. Evaluation of precursor and cofactor engineering strategies influencing fatty acid metabolism in Saccharomyces cerevisiae

   Författare :Alexandra Linda Bergman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; metabolic engineering; fatty acids; oleochemicals; NADPH; Sustainability; phosphoketolase; acetyl-CoA; transcription factor;

   Sammanfattning : If humanity is to reduce the rate of climate change, it is essential that our societies switch to a more sustainable production of fuels and chemicals, which in turn depends on technological development. Oleochemical production via microbial catalysts – such as the yeast Saccharomyces cerevisiae – can use a considerably broader range of renewable substrates compared to the conventional production processes.

4. 8. Identification and imaging of lipids in tissues using TOF-SIMS

   Författare :Ylva Magnusson; Göteborgs universitet; []
   Nyckelord :mass spectrometry; lipids; fatty acids; diacylglycerols; triacylglycerols; TOF-SIMS; adipose tissue; aortic wall; skeletal muscle; obesity; principal component analysis;

   Sammanfattning : Introduction: Normal lipid metabolism in the adipose tissue, skeletal muscle and aortic wall is important for the physiological function of these tissues. Dyslipidemia that is often associated with intake of high energy diet and sedentary lifestyles can lead to the development of insulin resistance and cardiovascular diseases. LÄS MER

5. 9. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

   Författare :Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.

7. 10. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

   Författare :Tannaz Ghaffarzadegan; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

   Sammanfattning : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. LÄS MER
