Photosynthetic Pigments in Diatoms
Photosynthetic pigments are bioactive compounds of great importance for the food, cosmetic, and pharmaceutical industries. They are not only responsible for capturing solar energy to carry out photosynthesis, but also play a role in photoprotective processes and display antioxidant activity, all of which contribute to effective biomass and oxygen production. Diatoms are organisms of a distinct ...

متن کاملDevelopment of sensitized solar cells by photosynthetic pigments
Background Grätzel solar cell, also known as dye-sensitized solar cell (DSSC), is a dye-sensitized nanocrystalline photovoltaic cell of TiO2 (titanium dioxide). It has a surface of nanoporous TiO2, a semiconductor of a wide bandgap. The basic principle is to transform light energy into electrical energy. When a dye molecule absorbs light, an electron is replaced by an excited state, and this dy...
متن کاملFluorescence-ODMR of Light Harvesting Pigments of Photosynthetic Bacteria
The triplet state of photosynthetic pigments has been widely used in the past as an internal nonde structive probe for the geometric and electronic structure of the pigment-protein complexes of photo synthetic bacteria. Especially the reaction center complex (RC) has been intensively studied by means of ESR in high field and zero field [1—7]. Less is known about antenna complexes. So far only...
متن کاملHigher-Order Stark Spectroscopy: Polarizability of Photosynthetic Pigments
Stark spectra for nonoriented molecules with typical broad inhomogeneous line widths are obtained by applying an ac electric field and detecting the change in absorbance at the second harmonic of the field modulation frequency. The analysis of such data in terms of molecular parameters such as changes in dipole moment and polarizability is often difficult. We outline a new method, called higher...
