  1. 11. Modeling competitive adsorption of binary mixtures of volatile organic compounds

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Michelle Janus; [2023]
    Nyckelord :;

    Sammanfattning : Adsorption is a common technique for the removal of volatile organic compounds (VOCs) from industrial waste streams. The multi-component adsorption on zeolites, particularly the interactions between VOCs and water vapor is sparsely understood and is yet to be described by empiric and full-physical models. LÄS MER

  3. 12. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Felicia Andersson; [2023]
    Nyckelord :Quantum chemistry; Ferrocene; Silver; Ag 111 ; Plasma electrons; Surface chemistry; Electronic structure; DFT; Kvantkemi; Ferrocen; Silver; Ag 111 ; Plasmaelektroner; Ytkemi; Elektronstruktur; DFT;

    Sammanfattning : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. LÄS MER

  4. 13. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Louise Berild; [2023]
    Nyckelord :Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

    Sammanfattning : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. LÄS MER

  5. 14. Investigating the Adsorption of Per- and Polyfluoroalkyl Substances on Amine-functionalized Mesoporous Carbons

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :MOJISOLA SALISU; [2023]
    Nyckelord :Mesoporous carbon; PFOA; PFOS; PFAS; Rose Bengal; Adsorption;

    Sammanfattning : Water pollution is a profound ecological concern, exerting detrimental effects on human well-being, ecological systems, and animal life. Among the emerging contaminants that critically influence water quality and have garnered substantial scientific interest in recent times are per- and polyfluoroalkyl substances (PFAS). LÄS MER

  7. 15. Evaluation of two-stage GAC filtration for PFAS reduction in drinking water

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Söderberg; [2023]
    Nyckelord :Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

    Sammanfattning : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. LÄS MER
