  1. 1. A GREENER SOLUTION Investigating the potential use of Green Solvents to remove cellulose nitrate lacquer from silver objects

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Borén Evelina; [2022-07-05]
    Nyckelord :Sustainable Conservation; Green Solvents; Cellulose Nitrate; Lacquer; Coating; Silver;

    Sammanfattning : This thesis investigates the performance of non-hazardous solvent substitutes, so called “Green Solvents", for the removal of aged and unaged cellulose nitrate lacquer from silver surfaces. Literature research and preliminary tests resulted in four solvents of interest: ethyl acetate, ethyl lactate, propylene carbonate and dimethyl carbonate. LÄS MER

  3. 2. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Josep Plana Riu; [2022]
    Nyckelord :;

    Sammanfattning : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. LÄS MER

  4. 3. Effektivisering av produktionen av en ljudabsorbent i kartong

    M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Sammanfattning : Sontech International AB är ett företag som är specialiserade på ljudabsorbenter i metall och skum. De har tagit fram en ljudabsorbent i kartong med slitsar som går längs arket med ett avstånd på max 5 mm mellan dem. LÄS MER

  5. 4. Improvement and Development of Powder Spreadability Testing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Fabrice Rosala; [2021]
    Nyckelord :;

    Sammanfattning : With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. LÄS MER

  7. 5. Design and Calibration of Pneumatic Probes for Aerodynamic Testing

    Master-uppsats, KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Författare :Angelica Lejdeby; [2021]
    Nyckelord :;

    Sammanfattning : To develop turbomachines aerodynamic testing is an important part of the process. The performance testing this thesis will focus on is pressure measurements, which often is done using pneumatic probes. The pneumatic probes used in this project were a five-hole probe, a pitot probe and two different types of Kiel probes. LÄS MER
