    Master-uppsats, KTH/Tillämpad fysik

    Författare :Michael Neuman; [2023]
    Nyckelord :Biopolymer; Chitosan; Coating; Nanocomposite; Photocatalytic; Zinc oxide; Antimicrobial; Antiviral; Coronavirus COVID-19 ; Biopolymer; Kitosan; Beläggning; Nanokomposit; Fotokatalytisk; Zinkoxid; Antimikrobiell; Antiviral; Coronavirus COVID-19 ;

    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  3. 2. Towards finding model pollutants for predicting CEC adsorption on biochars : The suitability of using dyes as proxies for CEC removal efficiency to enable wastewater reuse

    Kandidat-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Alexandra Aveling; [2022]
    Nyckelord :;

    Sammanfattning : This study evaluated the use of common dyes as model pollutants for adsorption on biochar. Pollutant removal efficiency of five dyes and three CECs on three different biochars (SWP-550, SWP-700, NDG-SW) was evaluated, using both UV-VIS spectrophotometry and LC-MS/MS, to examine similarities and differences in adsorption performance.

  4. 3. Development of a Flow Dependent Chemical Reaction Model using CFD

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Östman; [2022]
    Nyckelord :CFD; Fluid mechanics; Rotating Bed Reactor; Ansys Fluent; Decolorization; CFD; Strömningsmekanik; Roterande Bäddreaktor; Ansys Fluent; Avfärgningsprocess;

    Sammanfattning : In many technical applications chemical reactions are used. One of these is a so called decolorization, in which an ion exchange resin is used to remove a dye from water. To apply this decolorization technique a Rotating Bed Reactor, or RBR for short, can be used. It is filled with the ion exchange resin and spun inside the water. LÄS MER

  5. 4. Permeability of temporary restorative materials exposed to underwater pressure

    Master-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Elias Sjöberg; Daniel Hallin; [2020]
    Nyckelord :dental leakage; dental restoration; dental restoration temporary; diving; pressure; naval medicine;

    Sammanfattning : Området submarin miljö och dentala förhållanden finns det få studier inom. Detta ger behandlare svårigheter att ta evidensbaserade behandlingsbeslut för grupper som utsätts för hyperbariskt tryck. För att kunna föra fram kvalitativa studier och odontologisk kunskap krävs tillförlitliga metoder. LÄS MER

  7. 5. Phosphorus Removal and Methylene Blue Adsorption by Porous Calcium Silicate Hydrate.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Asanka Welagedara; [2013]
    Nyckelord :Absol; Batch experiment; Sorption capacity; Adsorption kinetic; ;

    Sammanfattning : Nutrients (nitrogen and phosphorus) should be removed and recycled from wastewater in order to reduce the nutrient load to recipient waters, avoiding contamination of groundwater and conserve resources. There is a need to pay more attention to phosphorus (P) removal and recycling from wastewater due to limited availability of phosphorus recourses. LÄS MER
