Memory effects in the fluorescence depolarization dynamics studied within the B850 ring of purple bacteria

Article Abstract:

The time dependence of the anisotropy of the fluorescence in the B850 ring of the purple bacterium Rhodopseudomonas acidophila is calculated using the reduced density matrix formalism. The calculations that are obtained with the non-Markovian theory based on the decomposition of the spectral density and a time-convolutionless approach are discussed.

Decomposition of hydrogen peroxide at water-ceramic oxide interfaces

Article Abstract:

Examination of the strong oxidants produced in the decomposition of hydrogen peroxide, H2O2 was done in a number of contexts including supercritical fluid oxidation, environmental remediation, and nuclear reactor corrosion. Also, the decomposition of H2O2 in the presence of various solid oxide particles is investigated.

Computer simulation of the exciton transfer in the coupled ring antenna subunits of bacteria photosynthetic systems

Article Abstract:

The ring structure of the subunits LH2 and LH1 of the purple bacteria antenna systems has been investigated. Attention focused on a delivery time of the energy through the subunits LH2 and LH1 of the antenna system to the reaction centre.
