  1. 6. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : William Gulding; [2023]
    Keywords : Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Abstract : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. READ MORE

  3. 7. Treatment of Metals in Highway Runoff Water : Comparison of green infrastructures and filter material for stormwater treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fanny von Matérn; [2023]
    Keywords : Road runoff; heavy metals; constructed wetland; stormwater pond; vegetated filterstrip; vegetated swale; sandfilter; reactive filter material; Vägdagvatten; tungmetaller; anlagd våtmark; dagvattendam; översilningsyta; svackdike; sandfilter; reaktiva filtermaterial;

    Abstract : Highway runoff transport high concentrations of heavy metals. As climate change affect the environment with for example increased storm events, the treatment of road runoff becomes more important. READ MORE

  4. 8. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alena Niarezka; [2023]
    Keywords : Ertelien Ni-Cu deposit; ore geology; enrichment processes; nickel; cobalt; copper; optical microscopy; electron probe micro-analysis; critical metals; Ertelien Ni-Cu fyndighet; malmgeologi; anrikningsprocesser; nickel; kobolt; koppar; optisk mikroskopi; elektronsondsmikroanalys; kritiska metaller;

    Abstract : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. READ MORE

  5. 9. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    University essay from Lunds universitet/Materialteknik

    Author : Johan Ranstad; [2023]
    Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

  6. 10. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE
