  1. 1. 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.

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

    University essay from KTH/Kemiteknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för kemivetenskap (CHE)

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

    Abstract : 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. READ MORE

  6. 5. : Extraction of β-carotene from orange peel and carrot waste for cotton dyeing

    University essay from Högskolan i Borås/Institutionen Textilhögskolan

    Author : SUSAN HECKER; [2014]
    Keywords : β-carotene; carrot and orange peel residue; organic solvent extraction; cotton dyeing;

    Abstract : The further usage of vegetable and plant waste from juice pressing industry as textile dyes is presented in this thesis. The thesis is focused on β-carotene (C40H56) dyestuff extracted from orange peel and carrot residue. The three organic solvents; ethyl acetate, petroleum ether and hexane/acetone (1:1 v/v) were used for the extraction. READ MORE
