  1. 1. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linda Péroux; [2022]
    Keywords : Technology and Engineering;

    Abstract : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. READ MORE

  3. 2. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ross Roberts; [2020]
    Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

    Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

    Author : Gustav Hederfeld; [2018]
    Keywords : ;

    Abstract : The area of "Norra Hamnstaden" in Lidköping has been used for several different industires for more than 100 years and porcelain has been produced there since 1912. The sub-area studied in this thesis has been used as a landfill for industrial waste including waste from the local porcelain factory, Rörstrand. READ MORE

  5. 4. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure

    University essay from Lunds universitet/Mekanik

    Author : Martin Edung; [2017]
    Keywords : Diamond Anvil Cell; FEA; FEM; Structural; Transient; Temperature; Ansys; Ansys WB; Machine Drawings; ESS; European Spallation Source; Technology and Engineering;

    Abstract : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. READ MORE
