  1. 1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Chun Hei Ho; [2023]
    Keywords : Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Abstract : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. READ MORE

  3. 2. Phonons in 1-D Graphene Nanoribbons Probed with Raman Spectroscopy : Unraveling Fundamental Properties in 9-atom-wide Graphene Nanoribbons

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Angel Victor Labordet Alvarez; [2023]
    Keywords : 9-armchair graphene nanoribbons 9-AGNRs ; polarization Raman Spectroscopy PRS ; temperature-dependent Raman spectroscopy; thermal sensitivity; thermal stability; Grüneisen parameter χ ; anharmonicities; vibrational modes G; D; RBLM .; 9-armchair grafen nanoribbons 9-AGNRs ; polarisation Raman spektroskopi PRS ; temperaturberoende Raman spektroskopi; termisk känslighet; termisk stabilitet; Grüneisen parameter χ ; anharmoniciteter; vibrationslägen G; D; RBLM .;

    Abstract : This report employs advanced Raman spectroscopy techniques to investigate the fundamental properties of 9-AGNRs comprehensively. It is divided into two main sections addressing distinct aspects of 9-AGNR behavior. In the first section, Polarization Raman spectroscopy (PRS) probes phonon mode symmetries in 9-AGNRs. READ MORE

  4. 3. Thermal environment and design considerations of the Foresail-2 satellite mission

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Deepa Anantha Raman; [2023]
    Keywords : satellite; thermal control; radiation; heat transfer; boom;

    Abstract : The thermal design of small satellite missions is critical for ensuring the performance and longevity of onboard instruments. This thesis focuses on the thermal design of Foresail-2, a 6U CubeSat mission to Geostationary Transfer Orbit (GTO), specifically addressing the thermal challenges associated with the magnetometer located at the end of a long boom featured on the satellite.

  5. 4. Waste-derived hard carbon anode materials for sodium-ion batteries : The potential of using cardboard as precursor material in sodium-ion batteries for hard carbon production in Sweden

    University essay from KTH/Materialvetenskap

    Author : Axel Björlin; Alexander Hansson; Yanxi Lucie Zhou; [2023]
    Keywords : ;

    Abstract : In recent years, sodium ion batteries (SIBs) have emerged as a strong contender to lithium-ion batteries (LIBs). The most promising anode for the SIBs is hard carbon (HC), which can be derived from a wide variety of raw materials and waste globally. READ MORE
