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. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Sofia Tynelius; [2022]
   Keywords : Solar flares; the Sun; STIX; EUI; alignment; pointing;

   Abstract : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). READ MORE

4. 3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

   Author : Lassi Linnala; [2022]
   Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

   Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

5. 4. Assignment of heteronuclear methyl-NMR spectrum of the 44 kDa protein MALT1 Casp-IgL3

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Author : Maria Levkovets; [2022]
   Keywords : MALT1; NMR; methyl-NMR; protein NMR; Physics and Astronomy;

   Abstract : Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) plays an important role in the immune pathway that controls the activation and proliferation of B and T cells. Dysregularization of this pathway leads to the development of highly aggressive lymphomas. READ MORE

6. 5. Crime Concentration in Sweden : An Explorative Test of a Criminological Law

   University essay from Malmö universitet/Institutionen för kriminologi (KR)

   Author : Robert Breski; [2021]
   Keywords : Crime concentration; criminology of place; hot spots; micro geography; micro places;

   Abstract : According to the law of crime concentration, a certain percentage of crime is predicted to be concentrated at a certain percentage of microgeographic units, and relatively large amounts of crime are predicted to be accounted for by a small percentage of places. Given the lack of research testing the law in a Swedish context and for a whole country, this study set out to examine the concentration of crime at all densely populated areas in Sweden. READ MORE
