  1. 11. Creation of thin film CuSbSe2 through closed space vapor transportdeposition

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Malin Eriksen; [2018]
    Nyckelord :CuSbSe; CuSbSe2;

    Sammanfattning : With an increasing demand for fossil-free energy the development of efficient solar cells made from sustainable and abundant materials is needed. A promising group of new absorber materials are the chalcogenide materials, including the chalcostibnite compounds copper antimony selenide, CuSbSe2. LÄS MER

  3. 12. Photoelectrochemical Water-Splitting using 3C-SiC

    Master-uppsats, Linköpings universitet/Halvledarmaterial

    Författare :Pontus Höjer; [2017]
    Nyckelord :Silicon carbide; 3C-SiC; photoelectrochemical water-splitting; PEC; co-catalyst; ohmic contact;

    Sammanfattning : In 1972 Fujishima and Honda conceptualised a photoelectrochemical cell for hydrogen generation via PEC water splitting. Hydrogen as a clean energy carrier provides environmentally friendly energy storage solutions or can fuel certain applications. LÄS MER

  4. 13. 'I will work harder' : A Psychoanalytical Study of Boxer - the Horse, in Orwell's Animal Farm

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för humaniora

    Författare :Johanna Wermelin; [2017]
    Nyckelord :Animal Farm; Psychoanalysis; Orwell; Freud; Propaganda; Manipulation; Defense mechanisms; Denial; Sublimation;

    Sammanfattning : The novel Animal Farm was primarily written as a satire on the Russian revolution, with the underlying intention to actively warn readers what happens when a totalitarian regime takes power. Manipulation and propaganda play a central role in the novella, but the ways in which the regime abuses its people psychologically appears to be of even greater importance. LÄS MER

  5. 14. Hur påverkar snömängd och vindförhållande vattentrycksmätningar vintertid i en sjö på västra Grönland?

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Christina Truedsson Sjöström; [2016]
    Nyckelord :lake; climate; water pressure; Greenland; physical geography and ecosystem science; Earth and Environmental Sciences;

    Sammanfattning : During the Quaternary period, the climate has been dominated by glacial cycles resulting in periodic ice sheet coverage over Scandinavia and Sweden. In the scenarios for future climate development used in the assessment of long-term safety for planned repository of spent nuclear fuel, the possibility of future glaciations need to be considered.

  7. 15. A simulation of the propellant storage for a ice-propelled microresistojet engine : Development, verification and validation of a numerical model for the characteristics of a sublimation tank to be used as the propellant storage subsystem for a ice-propelled microresistojet engine

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Rasmus Bergström; [2016]
    Nyckelord :;

    Sammanfattning : An innovative design for a new type of propulsion sys-tem using sublimating water in solid form as reaction mass, accelerated via a Micro Electric Mechanical System (MEMS) Heater Chip, is currently being developed at the Space Sys-tems Engineering Department at Technische Universiteit Delft in the Netherlands. The aim of the thesis is to char-acterise the propellant storage and gain insight into the physics present in the engine. LÄS MER
