Ebook "Biomimetic dye aggregate solar cells" describes a new approach to the construction of solar cells. Following nature's example, this approach has the goal to find a biomimetic self-assembling dye, whose aggregates can mimic the natural light-harvesting system of special photosynthetic active bacteria. The thesis investigates methods to control the self-assembly such that suitable dye aggregates are formed with high internal order and size-confinement.

This photocatalyst's high degradation efficiency is attributed to the synergistic effect of plasmon-induced visible light-harvesting due to Ag and enhanced adsorption and electronetransport properties due to rGO. It is found that the Ag-induced surface plasmon characteristics of the nanocomposites are sensitive to rGO concentration.

Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. In this study, dye-sensitized solar cells (DSSCs) were fabricated using natural dyes light harvesting materials. The natural dyes were extracted from Acanthus sennii chiovenda flower and Euphorbia cotinifolia leaf.

As a new family of functional porous materials, conjugated porous polymers (CPPs) with tuneable porosities and molecular architectures show great potentials in adsorption, light harvesting, and catalysis applications. This paper describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs via Sonogashira coupling reactions.

The result, the photo-catalytic performance of the obtained Ag/STO hybrid photocatalyst was higher than that of the pristine STO nanocubes due to i) the efficient charge separation and transfer of photogenerated electron-holes pairs; ii) the improvement of the light-harvesting efficacy in the visible light. The high photo-catalytic RhB decomposition of the achieved Ag/STO hybrid photo-catalytic was obtained compared to the pure SrTiO3 nanocubes under UV and visible light exposure.

The use of light of different wavelengths has grown popular in the poultry industry. An optimum wavelength is believed to improve pigeon egg production, but little is known about the role of microRNAs (miRNAs) in the effects of monochromatic light on ovarian pigeon function. Herein, we harvested ovaries from pigeons reared under monochromatic light of different wavelength and performed deep sequencing on various tissues using an Illumina Solexa high-throughput instrument.

In this paper, we report the synthesis of rGO-TiO2 nanocomposite electrode and its effect on the performance of DSCs. The nanocomposite rGO-TiO2 photoelectrode was examined by means of current-voltage (I-V) characteristics of the solar cell when illuminated and in the dark. The results indicate that, unlike the Nb2O5 that forms an energy barrier at the surface and SrTiO3 that shifts the conduction band of the TiO2 in the negative direction, rGO doping allows more dye to be adsorbed due its large surface area thus improving the light harvesting efficiency (LHE).

Post-harvest processing and value addition is the most important aspect related to all the food products. Processing of agricultural commodities means converting the raw food material in to consumer acceptable form with increased shelf life and maintained nutritional quality. It can be achieved through various conventional food processing methods like drying, dehydration, evaporation, extrusion, freezing etc. The main lacunae with these conventional methods are loss of colour, flavour, vitamins and other nutrients due to higher temperature and longer processing time.

Phytyl residues are the common side chains of chlorophyll (Chl) and tocopherols. Geranylgeranyl reductase (GGR), which is encoded by CHLP gene, is responsible for phytyl biosynthesis. The light-harvesting like protein LIL3 was suggested to be required for stability of GGR and protochlorophyllide oxidoreductase in Arabidopsis.
