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. Drivers of sea level variability using neural networks

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Linn Carlstedt; [2023-05-10]
   Keywords : ;

   Abstract : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

4. 3. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Gustav Larsson; [2023]
   Keywords : organic solar cells; polymer; morphology; film; AFM;

   Abstract : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

5. 4. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

   University essay from Karlstads universitet

   Author : Marcus Roseen; [2023]
   Keywords : ;

   Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

6. 5. Impact of wetland restoration on river discharge - A case study of Bråån, Skåne, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ardis Luda; [2023]
   Keywords : wetlands; wetland restoration; HYPE model; river discharge; Sweden; land use change; flooding; hydrological modeling; Earth and Environmental Sciences;

   Abstract : Land use change is a factor not often considered when modeling river discharge in regard to future flood risk. The restoration of wetlands is an ongoing land use change which affects water storage capacity in the soils of a catchment and could lead to lower flows in rivers. READ MORE
