1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Emelie Zhu; [2024]
   Keywords : Physics and Astronomy; Technology and Engineering;

   Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

3. 2. Structural analysis of HZO thin film and electrode using X-ray diffraction

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Elliot Winsnes; [2024]
   Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

4. 3. 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

5. 4. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Henry Wittler; [2023-11-29]
   Keywords : ;

   Abstract : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. READ MORE

6. 5. Who Deserves to Be Included? Diffraction of Diversity and Inclusion in Swedish International Organizations

   University essay from Göteborgs universitet/Institutionen för kulturvetenskaper

   Author : Kanae Wada; [2023-08-21]
   Keywords : Diversity; Inclusion; Diversity management; Differences; Neoliberalism;

   Abstract : My thesis explores how diffraction on D&I is created by the entanglement of the nature of institution (institutional will and wall) and dissemination of neoliberal rationality, and how it perpetuates power relations that creates inequality and exclusion. I will explore this through critical discourse and intersectionality analysis thereby aiming to offer suggestions to improve diversity and inclusion (D&I) work at the Swedish organizations. READ MORE
