  1. 1. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Improving polarizing neutron optics by introducing 11B4C as interlayers

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Martin Falk; [2023]
    Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

    Abstract : 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. READ MORE

  4. 3. Tuning the Curie temperature and phase fraction of FeNi25-based alloys with Mn and Co for magnetocaloric applications

    University essay from KTH/Materialvetenskap

    Author : Marie Sanglé-Ferrière; [2020]
    Keywords : Thesis; magnetocaloric effect; Curie temperature; FCC; FeNi25; Avhandling; magnetokalorisk effekt; Curie-temperatur; FCC; FeNi25;

    Abstract : 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.

  5. 4. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Daniel Preis Bergdahl; [2016]
    Keywords : bedrock; Cole-Cole; resistivity; induced polarization; dyke; weathering; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  6. 5. Magnetic nanoparticles for novel biodetection assay techniques

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Christopher Lundgren; [2012]
    Keywords : ;

    Abstract : Water-based suspensions of single-core iron-oxide particles with nominal sizes 15 - 50 nm were studied by AC and DC magnetometry techniques, in order to determine their suitability for use in the volume amplified nanobead detection assay (VAM-NDA). The VAM-NDA can detect specific bio molecules, which have been magnetically tagged and volume amplified, by measuring the difference in the Brownian relaxation rate compared to a negative control sample.
