1. 11. Characterization of Multifunctional Nanomaterials for Electronics Thermal Management and Sintering Applications

   Författare :Abdelhafid Zehri; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The science of manipulating materials at their nanoscale level is nowadays allowing endless possibilities to disrupt the current limitations on the conventional production processes and products. In electronics, the need for more capable thermal management strategies led to the exploration of advanced approaches and focus on new materials and allowed to push further the thermal dissipation capabilities of each generation of products.

3. 12. Fire behaviour of upholstered furniture component materials at multiple scales

   Författare :Konrad Wilkens Flecknoe-Brown; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; upholstered furniture; Polyurethane; Scaling; Experimental; Modeling; fabric;

   Sammanfattning : In this research, both experimental test methods and computer models were used to characterise the thermal decomposition processes of selected upholstered furniture component materials, namely; flexible polyurethane foam and a range of different fabric coverings. This was first done at some of the smallest, simplest levels available, and how these materials were tested and the methods chosen to investigate them, was examined. LÄS MER

4. 13. PFAS in the water supply: source water contamination

   Författare :Dauren Mussabek; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source water; drinking water; per- and polyfluoroalkyl substances; PFAS; AFFF; UV treatment;

   Sammanfattning : Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. LÄS MER

5. 14. Circularity Assessment of Water and Waste in Cities : A Proposed Framework for Sustainable Performance Evaluation using LCA and LCC

   Författare :Kavitha Shanmugam; Venkata Krishna Kumar Upadhyayula; Mats Tysklind; Runar Brännlund; Brajesh Dubey; Umeå universitet; []
   Nyckelord :Life cycle assessment; life cycle costing; environmental externalities cost; sustainable city; circularity; wastewater treatment; organic waste; waste to energy; assessment framework; environmental science; miljövetenskap;

   Sammanfattning : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

7. 15. Characterisation of autophagy pathways in atherosclerosis

   Författare :Peter Saliba Gustafsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Atherosclerosis is an inflammatory disease of large to intermediate-sized arteries, characterised by retention of modified low-density lipoprotein within the vessel wall; this evokes an inflammatory response. Low-density lipoprotein carries lipids such as fatty acids, triglycerides and cholesterol, from the liver to peripheral tissues. LÄS MER
