  1. 1. Method for interfacial energy determination of gold nanoparticles on solid surfaces

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Mikaela Petersson; [2020]
    Keywords : Nanoparticles; sintering; interfacial energies; Young s equation; contact angle; Au; Si; silica; Sapphire; Al2O3; SEM; AFM; TEM; FFT; Science General;

    Abstract : The high surface-to-volume ratio of nanoparticles (NPs) makes them an interesting source for scientific research. How interfacial energies interplay between such a small structure and a solid bulk surface, are important because of the versatile applications NPs regard. READ MORE

  2. 2. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Tom Turner; [2020]
    Keywords : Bronäs; Sala;

    Abstract : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

  3. 3. Styles of mineralization in the Nautanen IOCG deposit

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nils Edblom; [2020]
    Keywords : Nautanen; Aitik; Gällivare; Norrbotten; IOCG; NDZ; nautanen deformation zone;

    Abstract : Nautanen is an IOCG (Iron Oxide Copper Gold) deposit located in northern Sweden, 10 km north-east of the town Gällivare in the county of Norrbotten. It was mined for copper for seven years in the early 1900´s and is presently explored by Boliden Mineral AB. The deposit sits within a package of shoshonitic andesites of the Porphyrite group.

  4. 4. Cultural encounters and cheap labor: An interrogation of the Danish au pair scheme

    University essay from Malmö universitet/Kultur och samhälle

    Author : Violeta Ligraien Yanez Hidalgo; [2019]
    Keywords : Domestic labor; Au pair; Philippines; Denmark; Labor migration;

    Abstract : The present paper interrogates the Danish au pair scheme’s legitimacy as a cultural exchange program. The paper will introduce the theory of a segmented labor market and situate the au pair scheme within an empirical context of a global demand for migrant domestic labor. READ MORE

  5. 5. Renormalization Group Evolution Analysis of the Gauged Froggatt-Nielsen Mechanism in 2-Higgs-doublet Models

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Robin Plantey; [2019]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis, we consider a 2-Higgs-doublet model with a gauged Froggatt-Nielsen mechanism as an extension of the standard model. We assume that (i) the theory at the electroweak scale is the low energy limit of a theory defined at a scale $\Lambda_{FN}$ (ii) the Yukawa couplings at $\Lambda_{FN}$ are generated by the Froggatt-Nielsen mechanism.
