  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johanna Bergström; [2023-09-15]
    Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

  3. 2. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Salim Charkas; [2023]
    Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

  4. 3. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Arvid Sandberg; [2023]
    Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  5. 4. Sargassum digestate as fertiliser in Grenada

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Lina Bengtsson; Theodor Halldin; [2023]
    Keywords : Sargassum; digestate; fertiliser; heavy metals; Sargassum; digestat; gödningsmedel; tungmetaller;

    Abstract : Surges of Sargassum have become more severe and at the time of writing the largest surge yet is set to hit the Caribbean islands, affecting tourism and marine life negatively. Tourism is Grenada’s single handedly largest economic sector, which is why it is important to research the use of Sargassum. READ MORE
