The adsorption of bidens pilosa dye molecules onto TiO2 nanoparicle surfaces for optimization of light harvesting efficiency in dye sensitized solor cell: an experimental and theory study
… to be between 420 nm and 665 nm with a higher light harvesting efficiency. pheophytin and porphyrin exhibited energy gaps of 2.1 eV and 2.8 eV respectively. This study demonstrates that the dye molecule synthesized from B. pilosa is an efficient sensitizer for DSSCs. The adsorption results …

Computational investigation of light harvesting in purple photosynthetic bacteria
… photosynthetic bacteria achieve remarkably high light harvesting efficiency, thus reconciling multiple competing processes in the chromatophore. The first step in photosynthesis is the capture and transport of light energy in the form of short-lived electronic excitation called excitons. Rapid …

M13 bacteriophage-enabled assembly of nanocomposites : synthesis and application in energy conversion devices
… solar cells, the electron collection efficiency is improved by the complex of the viruses and single-walled carbon nanotubes. The light harvesting efficiency is also improved by localized surface plasmon-enhanced photo-absorption of dye-molecules, with and without adding viruses into …

Potential Impacts of Climate Change on Photochemistry of <i>Zostera Marina</i> L.
… daily and seasonal variations of temperature and light, CO<sub>2</sub> enrichment consistently increased plant size, leaf thickness and chlorophyll use efficiency, and decreased pigment content and the package effect while maintaining similar light harvesting efficiency. These CO<sub>2</sub> …

Investigating the Electron Transport and Light Scattering Enhancement in Radial Core-Shell Metal-Metal Oxide Novel 3D Nanoarchitectures for Dye Sensitized Solar Cells
… IPCE, and EIS characteristics were studied. The efficiency, light scattering and charge transport properties of the core-shell nanowire based devices were compared to TiO<sub>2</sub> nanotube as well as TiO<sub>2</sub> mesoporous film based DSSCs. The Au nanowires inside the crystalline …

Beyond Suspension: Light and Growth Dynamics in Immobilised Algal Cultures
… this distribution, we studied the interaction of light with such immobilised cultures. As the algal aggregates strongly affect the light distribution within the colony, a comparative study between the heterogeneous distribution of cell aggregates in a gel matrix and a flat, uniform biofilm was …

Förster resonance energy transfer (FRET)-based nanophotonics using DNA origami structures
… by Förster resonance energy transfer (FRET). The efficiency of this energy transfer is highly dependent on the donor-acceptor distance. Hence, in these nanoscale photonic devices it is of high importance to have a good control over the spatial assembly of used fluorophores. Based on molecular …

Physico-chemical hydrodynamics of droplets on textured surfaces with engineered micro/nanostructures
… robust inkjet printer heads, or efficient fog-harvesting surfaces. Developing such functional surfaces requires interdisciplinary considerations that have not been broadly explored and which integrate principles from capillarity, optics, nanofabrication, hydrodynamics of complex fluids, and …
