• Ultrafast photodynamics of ZnO solar cells sensitized with the organic indoline derivative D149 

      Rohwer, Egmont Johann (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: The initial charge transfer from dye molecules' excited states to the conduction band of a semiconductor, after absorption of visible light by the former, is critical to the performance of Dye sensitized ...
    • Search for low-spin states above the 5-α break-up threshold in 20Ne 

      Swartz, Jacobus Andreas (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: The study of α clustering is a well-established topic of research in nuclear physics. Recent experimental evidence has revealed the first 2+ excitation of the Hoyle state in 12C, which is known to have ...
    • From stable priors to maximum Bayesian evidence via a generalised rule of succession 

      De Kock, Michiel Burger (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: We investigate the procedure of assigning probabilities to logical statements. The simplest case is that of equilibrium statistical mechanics and its fundamental assumption of equally likely states. ...
    • Combinatorics and dynamics in polymer knots 

      Rohwer, Christian Matthias (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: In this dissertation we address the conservation of topological states in polymer knots. Topological constraints are frequently included into theoretical descriptions of polymer systems through invariants ...
