1. 1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

   University essay from KTH/Fysik

   Author : Serena Ambrosino; [2024]
   Keywords : Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

   Abstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

3. 2. Integrating Waste Heat from Hydrogen Production Into District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fawzi Kayali; [2023]
   Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

4. 3. Methodology for Designing Bespoke Air Handling Units

   University essay from KTH/Energiteknik

   Author : Alexandra Malysheva; [2023]
   Keywords : bespoke air handling unit; evaporative cooling system; two-stage crossflow heat exchanger; 3D-modeling; platsbyggt luftbehandlingsaggregat; evaporativt kylsystem; tvåstegs motströmsvärmeväxlare; 3D-modeling;

   Abstract : This master's thesis explores the role of bespoke air handling units in enhancing energy efficiency in existing buildings. The context for the study is set against the backdrop of global initiatives, including the United Nations' Sustainable Development Goals, specifically Goal 7, which emphasizes the need to improve energy efficiency to combat climate change.

5. 4. Effects of Energy Performance Improving Measures on a 1990's Brick House in Southern Czech Republic : Computer Simulations using IDA-ICE

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Vaclav Panek; [2023]
   Keywords : Final energy demand; Primary energy demand; Energy performance; Refurbishment; Single-family house; Space heating;

   Abstract : The residential sector was responsible for 25% of the Final Energy Demand (FED) in the European Union in 2015. Countries in Central and Eastern Europe such as the Czech Republic are particularly concerned with ensuring security of supply at the lowest possible cost in recent years. READ MORE

6. 5. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Colin Potter; [2023]
   Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

   Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.
