  1. 1. Study on the Electronic Band Structure of the Spinel Superconductor LiTi2O4

    University essay from KTH/Tillämpad fysik

    Author : Gaia Di Berardino; [2022]
    Keywords : LiTi2O4; anomalous superconductivity; density functional theory; ARPES; electronic band structure; PLD; condensed matter physics; material science; LiTi2O4; okonventionell supraledning; funktionell densitetsteori; ARPES; elektronisk bandstruktur; PLD; kondenserade materiens fysik; materialvetenskap;

    Abstract : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. READ MORE

  3. 2. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

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

    Author : Filip Ivarsson; [2019]
    Keywords : Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. READ MORE

  4. 3. Fe-Mo-oxide of spinel structure for methanol oxidation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maria Thulin; [2016]
    Keywords : iron molybdate catalyst; methanol oxidation; Fe-Mo-oxide; spinel structure; formaldehyde catalyst; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The aim of this master thesis was to investigate a Fe-Mo-oxide catalyst of spinel structure for methanol oxidation to produce formaldehyde and determine if the spinel could be an alternative to the commercial Formox catalyst used today. This included firstly, synthesising the catalyst to get more knowledge of the formation of the structure and secondly, determine the activity, selectivity to formaldehyde and stability of the catalyst.

  5. 4. Mineral Chemistry and Parageneses of Oxyborates in Metamorphosed Fe-Mn Oxide Deposits

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Zacharias Enholm; [2016]
    Keywords : Oxyborates; in situ boron analysis; microchemical analysis; Raman analysis; Fe-Mn oxide deposits; Långban; Nordmark; Jakobsberg; Oxyborater; in situ boranalys; mikrokemisk analys; Ramananalys; Fe-Mn-oxidmalmer; Långban; Nordmark; Jakobsberg;

    Abstract : Oxyborate minerals can represent the most important sink for boron in silica-undersaturated mineralised systems such as those of the Långban-type. Yet, their distribution, characteristics and parageneses are still not completely known. READ MORE

  6. 5. Formation of cobalt oxide clusters on oxygen modified graphene

    University essay from Lunds universitet/MAX IV-laboratoriet; Lunds universitet/Fysiska institutionen
