Time-resolved fluorescence measurements of photosystem II: the effect of quenching by oxidized chlorophyll Z
Article Abstract:
Research was conducted to examine the effect of chlorophyll Z on the decay components in photosystem II (PS II) at low temperature using time-resolved fluorescence spectroscopy. To ascertain the redox state of the sample under the conditions of the fluorescence measurements, both EPR and fluorescence calculations were performed. Results are consistent with rapid exciton equilibration within the PS II core antenna.

A facile method to fabricate ZnO hollow spheres and their photocatalytic property
Article Abstract:
A simple method to prepare ZnO nanoshells with very good photocatalytic activity which involves the use the sulfonated polystyrene core-shell spheres as template is demonstrated. The wall thickness of ZnO spheres could be altered by addition Zn[(Ac).sub.2]*2[H.sub.2]O into the ethanol dispersion of the template spheres.

Excitation dynamics in the core antenna in the photosystem I reaction center of the chlorophyll d-containing photosynthetic prokaryote Acaryochloris marina
Article Abstract:
Transient absorption difference spectroscopy on the picosecond time scale is used to study the ultrafast excitation dynamics in the photosystem I core antenna in Acaryochloris marina, a newly discovered marine oxygenic photosynthetic prokaryote that contains chlorophyll d as its major photopigment.
