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

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

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

    Sammanfattning : 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.

  3. 2. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    Master-uppsats, KTH/Kemiteknik

    Författare :Nils Toll; [2021]
    Nyckelord :Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Sammanfattning : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. LÄS MER

  4. 3. Hälsingegårdarnas textila färglandskap Tänkbara kulörer, färgämnen och färgningsmetoder i Hälsingland 1750-1870

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Katarina Olars; [2017-03-27]
    Nyckelord :Natural dyes; textiles; Art Technological Source Research; Hälsningland; World Heritage;

    Sammanfattning : The purpose of this thesis is to explore the local textile tradition, primarily natural dyes and dyeing techniques used in farmhouses of Hälsingland between 1750- 1870. Issues addressed; why and how were certain organic natural dyestuffs used, which substances were used to create certain colours, and who carried out the dyeing. LÄS MER

  5. 4. Evaluation of Amyloid Fibrils as Templates for Photon Upconversion by Sensitized Triplet-Triplet Annihilation

    Kandidat-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Sharon Berkowicz; Helena Olsson; Henrik Broberg; [2017]
    Nyckelord :photon upconversion; sensitized triplet-triplet annihilation; anti-stokes emission; amyloid fibrils; whey protein;

    Sammanfattning : In the face of global warming and shrinking resources of fossil fuels the interest in solar energy has increased in recent years. However, the low energy and cost efficiency of current solar cells has up to this date hindered solar energy from playing a major role on the energy market. LÄS MER
