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

    University essay from Linköpings universitet/Kemi

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

    Abstract : 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. READ MORE

  3. 2. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Christina Henricson; [2023]
    Keywords : ;

    Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE

  4. 3. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Henriette Nishimwe; [2023]
    Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

  5. 4. Design and processing of metal-organic frameworks for greenhouse gas capture

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Evelina Wiksten; [2023]
    Keywords : Metal-organic frameworks; zeolitic imidazolate frameworks; carbon capture; gas adsorption; direct ink writing;

    Abstract : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. READ MORE

  6. 5. Moisture Transport in PA6

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emanuel Markström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. READ MORE
