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. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

4. 3. The Role of Small-Scale Photovoltaics in Transitioning to a Sustainable Energy System : Shining a light on Austria and Sweden

   University essay from Blekinge Tekniska Högskola/Institutionen för strategisk hållbar utveckling

   Author : Johannes Meusburger; Ekaterina Trofimova; Annefleur Muller; [2023]
   Keywords : ;

   Abstract : To tackle the global sustainability challenge, the energy system needs to transition towards a sustainable system, since it is responsible for two-thirds of global greenhouse gas emissions. To reduce emissions researchers urged for a 100% renewable based energy system, in which photovoltaic (PV) energy production is seen as a key component. READ MORE
