Photocatalysis is a fundamental feature of life processes on our planet (it provides photosynthesis in plants and bacteria) and of the chemistry of its atmosphere. Work is under way to develop photocatalytic technologies for abatement of environmental problems. The past two decades have witnessed a ...
We reinvestigate the influence of the pH on the rate constants of the redox transitions of the Mn complex (S-state transitions). For high-activity PSⅡ membrane particles from spinach, near-UV absorption transients (at 360 nm) induced by trains of ns-Laser flashes were analyzed....

Water resources management is of crucial importance for water assessments, water allocation, design and management of environmental systems. The overgrowing population, mainly in developing countries, and the prospective of climate change are calling for new approaches for water planning. Considering the ...
Role of nitrogen substitution in phenyl ring on excited state intramolecular proton transfer and rotamerism of 2-(2'-hydroxyphenyl)benzimidazole: a theoret... A comparative study of 2-(2′-hydroxy-3′-pyridyl)benzimidazole (2′,3′-HPyBI), 2-(3′-hydroxy-4′-pyridyl)benzimidazole (3′,4...
Carotenoids play the photoprotective role by virtue of their low-lying triplet states. They quench Chl and BChl triplet states, which can be populated under high light conditions, by triplet–triplet energy transfer [1]. In this way they prevent the formation of singlet oxygen, a harmful ...
Ycf3–Y3IP1 mainly facilitates the assembly of PsaA–PsaB, leading to the reaction centre subcomplex, and oligomeric Ycf4 facilitates the integration of peripheral PSI subunits. However, despite the central role of PSI in the light reaction of photosynthesis, in plants the data are limited to...
This band is substantially quenched upon P700 pre-oxidation, giving clear evidence for the intermediating role of the red Chl [21,22]. Although the very larger red shift of the emission peak of P. platensis PSI is striking, it has been revealed that the nature of the Chl responsible for ...
Photosystem I (PSI) and II (PSII) balance their light energy distribution absorbed by their light-harvesting complexes (LHCs) through state transition to maintain the maximum photosynthetic performance and to avoid photodamage. In state 2, a part of LHCI
