Abstract: Chlorophyll and betalain pigments extracted from scent leaves and flower of Bougainvillea Spectabilis were used as sensitizers for nanostructured TiO₂ based dye-sensitized solar cells (DSSCs), and their perfomances were investigated systematically. The light harvesting pigments have shown absorption in broad range of the visible region of the solar... Show More

Abstract: An evaluation index system was constructed for the coupling between urbanization and farmland resources, based on data from 31 provinces in the mainland of China. Using the Grey Relational Analysis method, the spatial-temporal variations of the coupling between them can be revealed. The conclusions of this study were: (1) the stress of urbanization...
