2. 1. Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

   Author : Lisandra Fachinello Krebs; Institutionen för arkitektur och byggd miljö; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Computer simulations; Extensive green roofs; Housing projects; Indoor thermal comfort; Leaf area index; Microclimate; Social housing; Sustainability; Thermal comfort;

   Abstract : Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. READ MORE

4. 2. Quantum chemical characterization of oxide nanoparticles and interactions on their surfaces

   Author : Marta Galynska; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cluster models; TiO2 nanoparticles; anatase; rutile; brookite; group-IV oxides; DFT;

   Abstract : Titanium dioxide and related oxide materials have been investigated using density functional theory calculations. Nanocrystalline particles were modelled by a finite cluster approach. READ MORE

5. 3. Micro-grids supplied by renewable energy : Improving technical and social feasibility

   Author : Caroline Bastholm; Ewa Wäckelgård; Annette Henning; Frank Fiedler; Kirsten Ulsrud; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; Electricity access; Decentralized; Off-grid; Photovoltacs; PV-hybrid; Micro-grid; Multi-disciplinary; Sociotechnical; Engineering Science; Teknisk fysik; Energy and Built Environments;

   Abstract : Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. READ MORE

6. 4. Novel electrode and photoelectrode materials for hydrogen production based on molecular catalysts

   Author : Andrew J. Bagnall; Leif Hammarström; Vincent Artero; Sascha Ott; Alexander Cowan; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical mechanism; hydrogen; artificial photosynthesis; molecular catalyst; hydrogen evolution; cobalt; Kemi; Chemistry;

   Abstract : The PhD project focussed on the application of a cobalt tetraazamacrocyclic complex, in the literature commonly referred to as [Co(CR)Cl2]+ as a molecular catalyst for the hydrogen evolution reaction (HER). This was within the broader scope of the EU MSCA H2020 ITN ‘eSCALED’ project, which primarily aimed to create artificial leaf devices for the storage of solar energy in chemical fuels and, as part of this, sought the development of novel bio-inspired and scalable materials.

7. 5. The Dynamics of Star Cluster Formation

   Author : Juan Pablo Farias Osses; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Star Cluster Formation; Star Formation; N-body simulations; Astronomy Astrophysics;

   Abstract : How do star clusters form? We care, since these are the birth sites of most stars, perhaps including our own Sun. There are a great variety of different theoretical models of cluster formation and our main goal in this thesis is to examine the implications of these for the dynamical evolution of a cluster's stellar population, including the ejected stars.
