1. FTIR mätningar av absorptionsvätskor i Bioenergy Carbon Capture and Storage processer
Kandidat-uppsats, KTH/KemiteknikSammanfattning : The effects of global warming are well understood. In order to combat this, society must move towards net zero emissions of green house gases, where carbon dioxide (CO2) plays a key role. In several IPCC climate scenarios that meet the Paris agreement, negative emission technologies that effectively remove CO2 from the atmosphere are included. LÄS MER
2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
3. Life cycle assessment of timber high-rise building structures : Case study of a project examined in the context of French environmental regulation (RE2020)
Master-uppsats, KTH/ByggnadsmaterialSammanfattning : The damages that the building sector does to the environment can no longer be ignored and need to be approached with a life cycle assessment (LCA). Advantages to build in wood and to build dense cities lead to a potential “two birds in one stone” effect regarding high-rise massive timber construction. LÄS MER
4. Design and processing of metal-organic frameworks for greenhouse gas capture
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. LÄS MER
5. Electrical Propulsion System Design of a Blended Wing Body UAV
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The conventional tube-and-wing aircraft has been around since the 1950s, with little to no innovative progress being made towards redesigning the conventional aircraft. The blended wing body (BWB) shape fuses the wing of the aircraft with the fuselage increasing structural strength while also increasing potential surface area to create lift, making it more efficient than conventional wing shapes.
