  1. 11. Modelling Local pH Values and Ion Distributions near Gold Nanoparticles

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Lisa Tete; [2021]
    Nyckelord :;

    Sammanfattning : Corrosion is the sum of processes by which an element, commonly a metal, wears away, deteriorates [1]–[3]. One of these processes uses the principle of electrochemistry as a basis, being the transfer of electrons between one chemical reaction and the element that undergoes corrosion [4], [5]. LÄS MER

  3. 12. Thermo-effector responses to a 5-day high-intensity cold-acclimation procedure

    Master-uppsats, KTH/Omgivningsfysiologi

    Författare :Frederick Wilkins; [2020]
    Nyckelord :Hypothermia Acclimation procedure thermo effector response;

    Sammanfattning : Long-term, repeated exposures to cold might lead to cold adaptation. The study examined, in a small homogeneous group of non-acclimatised men, the inter-individual response to a short-term, high-intensity cold acclimation regimen. LÄS MER

  4. 13. En Moving Bed Biofilm Reactor som försteg till en Långtidsluftad Aktivslam : Syresättningsförmågan och syrebehovets påverkan på energibehovet.

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Diana Klarström; [2020]
    Nyckelord :Biologisk rening; MBBR; LAS;

    Sammanfattning : The pulp and paper mill requires a lot of water during the production. Stora Enso Skoghall requires about 33m3 of water for 2204 lb produced carbon or paper. Before the wastewater returns to the recipient, the water must be purified from organic material. LÄS MER

  5. 14. Synthesis of single-layer graphene and studying oxidation behaviour of copper foil.

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Mouna Rafei; [2020]
    Nyckelord :;

    Sammanfattning : The ultimate aim of the current study is to investigate the electron transfer from copper (Cu) to single layer graphene through a thin Cu oxide layer. Therefore the project is divided into two main parts. LÄS MER

  7. 15. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

    Master-uppsats, KTH/Energiteknik

    Författare :Borbala Bernus; [2020]
    Nyckelord :LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

    Sammanfattning : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. LÄS MER
