2. 1. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

   Author : Åsa Magnusson; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; waste disposal; spent ion-exchange resins; mass balance assessment; Nuclear physics; environmental impact; Fysicumarkivet A:2007:Magnusson; nuclear power plant; Kärnfysik; Carbon-14;

   Abstract : This thesis presents the results from studies on carbon-14 produced by nuclear power reactors. Radioactive 14C enters the carbon cycle and can be taken up by humans, where it will constitute a potential health hazard. READ MORE

5. 3. Towards membrane engineering as a tool in cell factory design: A case study on acetic acid tolerance in Saccharomyces cerevisiae

   Author : Lina Lindahl; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; butanol; inhibitors; lipidomics; Key words: Lignocellulose; Zygosaccharomyces bailii; molecular dynamics simulations; membrane permeability; carbon-14 uptake; ethanol; robustness;

   Abstract : The sustainable production of fuels, chemicals, and materials using renewable resources is a necessity if we are to reduce our ecological footprint and the rate of climate change. Lignocellulosic biomass, the major constituent of plant cell walls, is a renewable raw material with great potential due to its high abundance. READ MORE

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

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

   Abstract : 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. 5. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

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

   Abstract : 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. READ MORE
