Quantitative Nuclear Magnetic Resonance Spectroscopy with Overhauser Dynamic Nuclear Polarization

ChemPhysChem, EarlyView.
Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for process monitoring. However, the quantitative analysis of highly diluted components or of components in small sample volumes is difficult with this analytical method due to its inherent lack of sensitivity. The hyperpolarization technique Overhauser dynamic nuclear polarization (ODNP)

Novel Asymmetric Iron Porphyrins for Photocatalytic CO2 Reduction to CH4

ChemSusChem, EarlyView.
Two novel asymmetric porphyrin‐based iron complexes capable of performing photocatalytic CO2 reduction (CO2R) to CO and CH4 with an organic photosensitizer are presented. 13CO2 labeling studies confirm CH4 is formed by CO2R. These earth‐abundant based complexes show significant potential for efficient CO2R beyond two electrons, joining a single ...

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
