2. 1. Reactions of aqueous radiolysis products with oxide surfaces : An experimental and DFT study

   Author : Cláudio Miguel Lousada Patrício; Mats Jonsson; Jean-Philippe Renault; KTH; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hydrogen peroxide; hydrogen production; metal; oxides; lanthanide; catalysis; density functional theory; surface; reactions; chemistry; SRA - Energy; SRA - Energi; SRA - Production; SRA - Produktion;

   Abstract : The reactions between aqueous radiolysis products and oxide surfaces are important in nuclear technology in many ways. In solid-liquid systems, they affect (and at the same time are dependent on) both the solution chemistry and the stability of materials under the influence of ionizing radiation. READ MORE

4. 2. Hydrogen, an Energy Carrier of the Future

   Author : Christian Hulteberg; Institutionen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Catalysts; Aerosols; Gasification; Hydrogen; Systems; Kemiteknik och kemisk teknologi;

   Abstract : The climate is changing, something that many scientists correlate to increased emissions of greenhouse gases. The effluent that is considered to have the highest impact on global warming is carbon dioxide, when effect and quantity are taken into account. READ MORE

5. 3. Cost-effective fuel choices in the transportation sector under stringent CO2-emission reduction targets - Global energy systems modelling

   Author : Maria Grahn; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; SOCIAL SCIENCES; Global energy systems; carbon dioxide emissions; biomass; liquid biofuels; primary energy price; transportation sector; hydrogen; carbon tax; energy scenarios;

   Abstract : This thesis analyzes the worlds future energy supply in general, and cost-effective fuel choices in the transportation sector in particular, under stringent CO2 constraints. The analysis is carried out with the help of a global energy systems model (GET), developed and modified specifically for each project. READ MORE

6. 4. Cost-effective fuel and technology choices in the transportation sector in a future carbon constrained world: Results from the Global Energy Transition (GET) model
