  1. 1. Berättelser utan ord : Kommunikation genom samisk materiell kultur

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Johanna Lundin; [2018]
    Nyckelord :Communication; Sápmi; identity; Sami; archaeological studies; jewellery; iron age;

    Sammanfattning : This essay aims to gain a deeper understanding for the beliefs and identity of the sami people in Sápmi, northern Scandinavia through observation of their material culture. More specifically the object of interest is different types of jewellery made from materials like horn, silver and tin dat- ed to iron age 500 BC to 1300 AD. LÄS MER

  2. 2. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rasmus Lavén; [2018]
    Nyckelord :Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Sammanfattning : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. LÄS MER

  3. 3. Study of leaching behavior of tin in Zinc-clinker and Mixed Oxide

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Olle Bertilsson; [2018]
    Nyckelord :Leaching; tin; Sn; Zn-clinker; Mixed Oxide; sulfuric acid; Zn; residue; H2SO4; Boliden;

    Sammanfattning : Due to the increasing usage of Sn in different electronics, such as solders and in touchscreens, together with Boliden Rönnskärs increased intake of electronic waste as a secondaryraw material, a Zn-containing product called Zn-clinker has increasing amounts of Sn. TheZn-clinker is shipped to Boliden Zn-smelter in Odda, where the Zn-clinker is mixed in withcalcine (roasted concentrate) and leached in several steps. LÄS MER

  4. 4. Measurement of particle yields induced by 200-MeV protons on multiple targets

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Rafael Antonio Lopez; [2018]
    Nyckelord :QFS; Quasi-free Scattering; 16O; 112Sn; 124Sn; FAIR; CsI Tl ; R3B; 6.3-MeV gamma; CALIFA; p; 2p ; Physics and Astronomy;

    Sammanfattning : One way to probe the structure of atomic nuclei far from stability is via quasi-free scattering (QFS) reactions. We conducted a (p,2p) QFS experiment on H2O, 112Sn, 124Sn and 208Pb targets in order to test the performance of CsI(Tl) detectors that are to be used in the upcoming R3B experiments at FAIR. LÄS MER
