  1. 21. Preparation and characterization of translucent glass ceramics

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Shahow Kakavandy; [2021]
    Keywords : ;

    Abstract : The purpose of this thesis is to prepare and characterize translucent glass ceramics. The procedure was as follows, first a general background of the field is presented where the problems with current dental glass ceramics are presented, together with their history. The need for a stronger material is then clarified with the addition of new metals. READ MORE

  3. 22. Anti-doping policy: : A comparative study of implementation in Iceland and Denmark

    University essay from Malmö universitet/Institutionen Idrottsvetenskap (IDV)

    Author : Torgils Gunnarsson; [2021]
    Keywords : Anti-doping; Anti-doping policy; The Code; Governance; Good Governance; Power; Interconnections;

    Abstract : This study investigates the differences and similarities in implementation of anti-doping policy in Denmark and Iceland. Various anti-doping themes has been chosen to dig deeper into the implementation on policies between the two countries which are related to: Economy, Education, Testing and Investigation, International Cooperation, Fitness and Public Health and Research and Development.

  4. 23. Tuning the composition of metallic nanoparticles for catalytic applications

    University essay from KTH/Kemi

    Author : Anthony Ropp; [2021]
    Keywords : catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

    Abstract : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. READ MORE

  5. 24. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

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

    Author : Simon Wozny; [2020]
    Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

    Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

  6. 25. Electrical analysis of interface recombination of thin-film CIGS solar cells

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Henrik Lotse; [2020]
    Keywords : interface recombination; SCAPS; activation energy; temperature dependent IV; dominant recombination path;

    Abstract : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).
