  1. 21. Investigating the effect of grinding method on ore beneficiation behaviour

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Mellisa Tanaka Mundida; [2023]
    Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Abstract : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. READ MORE

  3. 22. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Johannes Hall; Albin Larsson; [2023]
    Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE

  4. 23. Climate Impact of Wind Turbine Production : Emissions from Material and Energy Usage for Onshore and Offshore Wind Turbines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Joel Arnelo; Maria Kolte; [2023]
    Keywords : Wind turbine production; Wind turbine components; Onshore and Offshore wind power; Wind power climate impact; Produktion av vindkraftverk; Vindkraftverk komponenter; Landbaserad och havsbaserad vindkraft; Klimatpåverkan vindkraft;

    Abstract : Wind power is a renewable energy source that is making great strides in the global energy sector. While wind power is a renewable energy source, it is not entirely free from carbon emissions. This is because the production of wind turbines is dependent on the use of energy, and as a result can emit large amounts of carbon dioxide. READ MORE

  5. 24. Production and analysis of novel disulfide variants of Subtilisin Carlsberg

    University essay from Linköpings universitet/Kemi

    Author : Anton Elfstrand; [2023]
    Keywords : Subtilisin Carlsberg; Disulfide; Protein Engineering; Kinetic Stability;

    Abstract : Protein engineering has been used to alter the stability of proteins for several decades withmuch success, one approach being to introduce two cysteine residues that together form adisulfide bridge. The disulfide bridge can increase the Gibbs free energy of the transitionstate, thus increasing energy difference between the folded state and the unfolding transitionstate, leading to increased kinetic stability of the protein.

  6. 25. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE
