    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.

    Sammanfattning : Based on the results obtained from this study, no traces of chalk can be seen with the naked eye or through chemical analyzes of samples from rock carving premises that were chalked at least 4 years ago. Chalk consists mainly of calcium carbonate (CaCO3) and/or calcium sulphate dihydrate (CaSO42H2O), these can be extracted from the soil or produced by chemical means. LÄS MER
