Escherichia coli DNA photolyase is an enzyme that repairs the major kind of UV-induced lesions, cyclobutane pyrimidine dimer (CPD) in DNA utilizing 350-450 nm light as energy source. The enzyme has very high photo-repair efficiency (the quantum yield of the reaction is ~0.85), which is significantly greater than many model compounds that mimic photolyase. This suggests that some residues of the...

The Cover Feature illustrates the concept of cooperative catalysis between supported metal single atoms and nanoparticles, which could be operative in various conventional catalysts is discussed by P. Serp his Review. Different types synergies can (co)exist, involving or not a communication these two species, are presented relative to their involvement thermal-, electro- photo-catalysis.

The integration of Atomic Force Microscopy and Raman spectroscopy is tested for use in heterogeneous catalysis research by a preliminary investigation, the photo-oxidation of rhodamine-6G. Temperature and atmosphere were varied in an in situ cell to show compatibility with realistic reaction conditions.

Visible-light-derived O(2) production was yielded by conjugating water oxidation catalysis by [(OH(2))(terpy)Mn(μ-O)(2)Mn(terpy)(OH(2))](3+) as an oxygen evolving center model and photo-sensitization of [Ru(bpy)(3)](2+) as a photoexcitation center model at an interlayer of mica.
