  3. 2. Synthetic gel particle formation for acoustofluidic applications

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Thibaut Valery; [2022]
    Keywords : agarose gel particles; acoustofluidics; droplet generation; microfluidic chip; Technology and Engineering;

    Abstract : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. READ MORE

  4. 3. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Aamanda Chang; [2021]
    Keywords : Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

    Abstract : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. READ MORE

  5. 4. Investigation of the zinc re-grinding circuit at Boliden Garpenberg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nils Merum; [2021]
    Keywords : Flotation; re-grinding; Garpenberg; Boliden;

    Abstract : Boliden’s mineral processing plant in Garpenberg wanted to investigate their zinc-regrinding circuit. The re-grinding circuit had performed subpar when running as the total recovery of zinc was lowered and problem with the dewatering of the final concentrates was also noted. Therefore, the zinc re-grinding circuit is currently not being used. READ MORE

  6. 5. Separation of Nanoporous Silica Particles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Frida Preuss; Julia Asp; Sofia Larsson; Stephanie Kylington; [2020]
    Keywords : Monodispersity; particle size distribution; density gradient; centrifugation; silica;

    Abstract : In this study a sample of particles in a size region of 0.05-10 μm were run through a centrifugation process with the ambition to make it monodisperse. The product requirements were stated as follows, particles within the size range of 2 to 3.8 μm should be isolated and separated from the sample with a D90/D10 < 1. READ MORE
