  2. 1. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs

    Author : Maria Anderson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy fuel oil; emission factor; marine fuel; black carbon; marine diesel oil; LNG; ship emission; liquefied natural gas; nanoparticle;

    Abstract : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. READ MORE

  4. 2. Non-Azeotropic Mixtures as Working Fluids in Heat Pumps: A theoretical and experimental study

    Author : Marine Högberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCFC123; HCFC124a; HCFC22; performance comparison; COP; non-azeotropic mixture; capacity; sensitivity analysis; HFC152a; heat pump; CFC114; ethyl chloride; experimental study; HCFC142b; two-stage cycle;

    Abstract : Due to the fact that CFC (Chloro-Fluoro-Carbon) fluids will be forbidden as working fluids in heat pumps for environmental reasons, there is an urgent need for alternatives. As one alternative type of fluid, non-azeotropic mixtures have been suggested. This thesis deals with such mixtures. READ MORE

  5. 3. Primary Marine Aerosol Production : An experimental study based on Arctic Ocean water and a sea water proxy

    Author : Julia Zábori; Margareta Hansson; Gordon McFiggans; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; primary marine aerosol; climate change; sea water physical properties; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : This thesis focuses on the interplay between the physical properties of ocean water and primary marine aerosol (PMA) emissions in the context of a rapidly changing Arctic climate. PMAs are an important part of the climate system due to their ability to interact with incoming solar radiation and to influence cloud properties. READ MORE

  6. 4. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE
