    • Morphological and Chemical Composition Characterization of Commercial Sepia Melanin 

      Mbonyiryivuze, Agnes; Nuru, Z. Y.; Ngom, Balla Diop; Mwakikunga, Bonex; Dhlamini, Simon Mokhotjwa; Park, Eugene; Maaza, Malik (Science and Education Publishing, 2015)
      Melanins are difficult to characterize because of their intractable chemical properties and the heterogeneity in their structural features. Melanin pigments, in fact, are composed of many different types of monomeric units ...

    • Natural Dye Sensitizer for Grӓtzel Cells: Sepia Melanin 

      Mbonyiryivuze, Agnes; Omollo, Isaiah; Ngom, Balla Diop; Mwakikunga, Bonex; Dhlamini, Simon Mokhotjwa; Park, E.; Maaza, Malik (Science and Education Publishing, 2015)
      The efficiency of Grätzel cell can be further improved by the anchoring groups, such as COOH to be adsorbed onto the TiO2 surface with a large electronic coupling. Some of the most efficient sensitizers are synthetic dyes ...
