1. 21. Approaches to scale-up CO2 emissions reduction in the energy supply sector in developing countries

   Författare :Wathanyu Amatayakul; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sectoral no-lose target; electricity generation; biomass; CO2 abatement; Thailand; CDM; developing countries; biofuel;

   Sammanfattning : This thesis, which consists of five papers, addresses two themes related to the need for a scale-up of greenhouse gas (GHG) emissions reduction in the energy sector in developing countries: (1) approaches to support developing countries in scaling-up emissions reduction, and (2) an approach to scale-up emissions reduction --cultivation of fuel wood to replace fossil fuels in electricity generation.In the first paper, the potential volume of carbon dioxide (CO2) emissions reduction and reduction credits in the electricity sector under a sectoral crediting mechanism based on a sectoral no-lose, non-binding, target in the post-2012 period is assessed for seven high-emitting developing countries by means of different scenarios.

3. 22. Model-based Analysis and Design of Atomic Layer Deposition Processes

   Författare :Anders Holmqvist; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic layer deposition; Heterogeneous reaction kinetics; Limit-cycle dynamics; Parameter estimation; Multi-objective optimization; Dynamic optimization; Scale-up analysis;

   Sammanfattning : Atomic layer deposition (ALD) is a thin-film manufacturing process in which the growth surface is exposed to non-overlapping alternating injections of gas-phase chemical precursor species separated by intermediate purge periods to prevent gas-phase reactions. ALD is characterized by sequential self-terminating heterogeneous reactions between highly reactive gas-phase precursor species and surface-bound species which, when allowed sufficient conditions to reach saturation, results in highly conformal films, on both planar and topographically complex structures.

4. 23. Foaming of cellulose derivatives and hemicellulose-containing materials

   Författare :Kristina Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; β-glucan; arabinoxylan; scale-up production; hydroxypropyl methylcellulose HPMC ; ethyl hydroxyethyl cellulose EHEC ; hot-mould foaming; extensional viscosity; extrusion; hemicellulose; rheological characterisation; Foaming; xylan; cellulose derivatives;

   Sammanfattning : Fossil-based polymeric foams are important materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. They are widely used in cushioning, absorbing and insulation applications. There are however a few disadvantages with these foamed products. LÄS MER

5. 24. Foaming of Some Cellulose Derivatives - Initial Studies

   Författare :Kristina Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological characterisation; Foaming; hydroxypropyl methylcellulose HPMC ; scale-up production; ethyl hydroxyethyl cellulose EHEC ; hot-mould baking; cellulose derivatives; extrusion;

   Sammanfattning : Fossil-based polymeric foams, based on polymers such as polystyrene and polyurethane, are important and widely employed materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. There are however a few disadvantages with these foamed products. LÄS MER
