Reconstruction of the biogeochemistry and ecology of photoautotrophs based on the nitrogen and carbon isotopic compositions of vanadyl porphyrins from Miocene siliceous sediments [PDF]
Biogeosciences, 2008 We determined both the nitrogen and carbon isotopic compositions of various vanadyl alkylporphyrins isolated from siliceous marine sediments of the Onnagawa Formation (middle Miocene, northeastern Japan) to investigate the biogeochemistry and ecology of ...

Interfacial Photoelectrochemistry in Organic Synthesis
Angewandte Chemie International Edition, Volume 64, Issue 42, October 13, 2025.Heterogeneous photoelectrodes are widespread for activations of H2O and CO2, while homogeneous photoelectrochemistry with molecular catalysts dominates complex molecule activations in synthesis. Nonetheless, interfacial photoelectrochemistry (iPEC) offers great potential for synthesis, including catalyst cost‐efficiency, reusability, and stability ...
