    Kandidat-uppsats, Göteborgs universitet/Steneby - Institutionen för Konsthantverk och Design

    Författare :Arttu Halkosaari; [2020-09-25]
    Nyckelord :Forging; Tactility; Touch; Plasma cutting; Blacksmith; Texture; Contrast;

    Sammanfattning : This exam project will be a conclusion for a long working process which started a year and a half ago. During this time, I have developed my own way of working with a plasma cutter and use that with different forged forms to create sculptures with varying textures. LÄS MER

  2. 2. Passivation of Gallium Arsenide Nanowires for Solar Cells

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Austin Irish; [2019]
    Nyckelord :nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

    Sammanfattning : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. LÄS MER

  3. 3. In-line Phase-contrast Tomography using Betatron X-rays Produced by a Laser-Plasma Accelerator

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Kristoffer Svendsen; [2017]
    Nyckelord :source size; x-ray; in-line; phase-contrast; phase contrast; LWFA; laser wakefield acceleration; tomography; diffraction; diffraction simulation; laser-plasma acceleration; Physics and Astronomy;

    Sammanfattning : X-ray phase-contrast imaging is a powerful technique that allows great resolving power for low absorbing samples, such as biological tissue. This method relies on measuring the phase shift induced by the sample instead of the absorption traditional radiography relies on. LÄS MER

  4. 4. Fatigue Life Assessment of Cut Edges in High Strength Steel

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Ilona Barmicho; [2016]
    Nyckelord :;

    Sammanfattning : The interests in more effective and lighter structures have increased the use of high strength steels for higher performances. Plate materials are optimized so thinner structures and higher material strengths are reached, this leads to the cut quality might be a new issue. LÄS MER

  5. 5. Evaluation and optimization of cation exchanging materials for life-span optimization of engine oil

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiLinköpings universitet/Tekniska högskolan

    Författare :Mima Ceco; [2013]
    Nyckelord :cation exchanger; buffering additive; engine oil; total base number; pIH method; inductively coupled plasma atomic emission spectroscopy;

    Sammanfattning : Requirements of high performing engine oil are today necessary since the development of new machinery with modern standardsis a cutting edge technology demanding highly optimized components. One way of increasing the lubricating properties of engineoil is through the addition of antioxidants. LÄS MER
