1. 6. Prospects for a Free Electron Laser at the FemtoMAX Beamline

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Johan Holmberg; [2024]
   Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

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

   Master-uppsats, KTH/Fysik

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

   Sammanfattning : 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. LÄS MER

4. 8. The active phase of Pt(110) during catalytic CO oxidation

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Hira Qazilbash; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER

5. 9. Nya metoder för fernissaborttagning – En komparativ studie

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Alica Larsson; [2023-11-08]
   Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

   Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

7. 10. Bilddiagnostik av barn ochungdomar vid skolios : En jämförande litteraturstudie mellan konventionell röntgen, datortomografi och entrepreneurial operating system

   Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

   Författare :Ida Söderberg; Van Najm; [2023]
   Nyckelord :Computed tomography; conventional radiography; entrepreneurial operating system; image diagnostics; radiation dose; Bilddiagnostik; datortomografi; entrepreneurial operating system; konventionell röntgen; stråldos;

   Sammanfattning : Bakgrund: Konventionell röntgen, datortomografi (DT) och entrepreneurial operating system (EOS) är tre radiologiska undersökningsmetoder som kan användas för bilddiagnostik vid skolios av barn och ungdomar. Undersökningarna kan genomföras i en liggande eller stående positionering vid bedömning av ryggradens deformation. LÄS MER
