Anthocyanin-sensitized nanoporous TiO2 photoelectrochemical solar cells prepared by a sol–gel process
(Springer, 2004)
Photoelectrochemical solar cells comprising a colloidal TiO2 photoelectrode and sensitized with anthocyanin pigments, delphinidin purple and cyanidin 3,5-diglucose extracted from Hibiscus sabdariffa and Ribes nigra plants, ...
Palaeo-research in Africa: relevance to sustainable environmental management and significance for the future
(2004)
Africa’s environment is closely linked with its climate, so that climatic constraints have been a major force in the development of vegetation, soils, agriculture and general livelihood (Nicholson 2001). The African ...
Tris(2-pyridyl)phosphine oxide: how C-H.O and C-H.N interactions can affect crystal packing efficiency.
(2004-04)
Tris(2-pyridyl)phosphine oxide, (I), C(15)H(12)N(3)OP, is isomorphous with tris(2-pyridyl)phosphine. Because of a combination of C-H.O and C-H.N interactions, the crystal packing is denser in the title compound than in the ...
Larvicidal benzoquinone from Embelia schimperi
(2004)
Chromatographic analysis of air-dried berries of Embelia schimperi led to the isolation of methyl vilangin (1), which was characterized on the basis of physical and spectroscopic data. The compound was found to be lethal ...
