  1. 1. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    University essay from Karlstads universitet

    Author : Marcus Roseen; [2023]
    Keywords : ;

    Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

  3. 2. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  4. 3. Development and Characterization of Parallel-Plate Avalanche Counters for Nuclear Physics Experiments

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Matthias Carlsson; [2018]
    Keywords : PPAC; Parallel-Plate Avalanche Counters; Gas Ionizing Detector; Gas Amplification; Characterization; NFS; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles; Time Resolution; Angular Dependence; Gas Pressure Dependence; Townsend Coefficient; PPAC Design; Manufacture; Manufacturing; Mylar foil; Aluminium Evaporation;

    Abstract : Parallel-plate avalanche counters, PPACs, are commonly used to detect fission fragments. The PPAC detects them and mark (very accurately) the time of detection. Such measurements can be used to measure the neutron energy (via time-of-flight) to study neutron-induced fission. READ MORE

  5. 4. Stormwater management in Gaborone - A study of the quality and quantity of water in Segoditshane River

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hanna Palm Johansson; Elin Andersson; [2015]
    Keywords : water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : This master thesis was partly performed as a field study in Gaborone, the capital city of Botswana, located in southern Africa. The semi-arid climate in Botswana together with a rapid financial development in the country during the last decades has increased the need for water. READ MORE

  6. 5. Reduction of hydrogen embrittlement on Electrogalvanized Ultra High Strength Steels

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Adam Haglund; [2014]
    Keywords : hydrogen embrittlement; electrogalvanized; ultra-high strength steel; martensite; vacuum evaporation; decarburization; hydrogen relief treatment; väteförsprödning; elförzinkning; ultrahöghållfast stål; martensit; vakuumförångning; ytavkolning; väteutdrivning;

    Abstract : Ultra-high strength steels is known to be susceptible for hydrogen embrittlement at very low concentrations of hydrogen. In this thesis three methods to prevent or reduce the hydrogen embrittlement in martensitic steel, with tensile strength of 1500 MPa, were studied. READ MORE
