1. A Geophysical Survey of Northern Utö
Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. LÄS MER
2. Improving polarizing neutron optics by introducing 11B4C as interlayers
Master-uppsats, Linköpings universitet/TunnfilmsfysikSammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER
3. Tuning the Curie temperature and phase fraction of FeNi25-based alloys with Mn and Co for magnetocaloric applications
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This paper discusses the search of an FeNi25-based alloy with a face-centered cubic crystal structure exhibiting a Curie point around room temperature, for magnetocaloric applications. Fe was substituted in various amounts with FCC-stabilising elements Mn and Co as these elements respectively decrease and increase the Curie Temperature, thus enabling to tune the Curie point.

4. Undersökning av mindre förkastningar för vattenuttag i sedimentärt berg kring Kingelstad och Tjutebro
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : På gränsen mellan Helsingborgs och Bjuvs kommun ligger ett område vars förutsättningar för grundvattenuttag bedöms vara dåliga. Av den anledning har en undersökning utförts över en förkastning, tolkad av SGU i just detta område, för att se om denna kan vara vattenförande eller om det kan finnas andra vattenförande strukturer i berget.

5. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : For both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. LÄS MER
