Dye-sensitized solar cells (DSSCs) were assembled by using the bougainvillea flowers, red turnip and the purple wild Sicilian prickly pear fruit juice extracts as natural sensitizers of TiO(2) films. The yellow orange indicaxanthin and the red purple betacyanins are the main components in the cocktail of natural dyes obtained from these natural products. The best overall solar energy conversion...
Kinetin-8-(14)C degraded rapidly upon drying on living or inert surfaces. However, when care was exercised to avoid taking solutions to dryness during fractionation of plant extracts containing (14)C-kinetin and before partitioning by thin layer chromatography, little degradation occurred. A procedure for 24-hour ethyl acetate partitioning, using a continuous liquid-liquid extractor, which perm...
Frost is the coating or deposit of ice that may form in cold conditions, usually overnight. If the temperature drops far enough for the plant cells to freeze, non hardy plants will die. Therefore, a research was laid out to study the influence of an anti-frost solution on growth, flowers quality and biochemical parameters of ornamental plants. The anti-frost solution was applied as foliar spray...
