   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Nsioh Elvis Nkioh; [2022]
   Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

3. 17. The Development of a Model for Determining the Spatial Resolution of Pulsed-Neutron Sources

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

   Author : Michael Byrnes; [2022]
   Keywords : Physics and Astronomy;

   Abstract : This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning across a one dimensional object of known dimensions.

4. 18. Validering av marklavskartering som underlag för renskötseln : en jämförelseanalys av fältbedömd marklavsförekomst med modellbaserad lavkarta

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Karin Nutti Pilflykt; [2022]
   Keywords : marklavskartering; rennäring; skogsbruk; Cladonia;

   Abstract : Since the 1950s, clear-cutting has been the dominant way of managing the Swedish forest. This has resulted in even aged forests and denser stands that have a negative impact on the distribution of terrestrial lichens. READ MORE

5. 19. Comparative investigation of micromechanisms of plastic deformation by in-situ tensile tests of highly textured 316L steel

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Subhani Kumarasinghe; [2022]
   Keywords : Additive manufacturing; texture control; plastic deformation;

   Abstract : Additive manufacturing (AM) is identified as one of the best techniques in manufacturing components addressing most of the current challenges including material scarcity, design complexity, material compatibility, etc. Stainless steel 316L is one of the promising material candidates in AM due to its extraordinary properties that are useful in a wide variety of industries.

6. 20. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Jennifer Silander; [2022]
   Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

   Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE
