Isotope Ratio Monitoring Gas Chromatography Mass Spectrometry (IRM-GCMS) [PDF]

On Earth, the C-13 content of organic compounds is depleted by roughly 13 to 23 permil from atmospheric carbon dioxide. This difference is largely due to isotope effects associated with the fixation of inorganic carbon by photosynthetic organisms.

Tuning Transition Metal 3d Spin state on Single‐atom Catalysts for Selective Electrochemical CO2 Reduction

Advanced Materials, EarlyView.
The introduction of P into a single‐atom Fe catalyst is shown to induce a shift in its electronic configuration toward a high spin state. This is proposed to enhance electron back donation via the dxz/dyz‐π* bond, which improves *COOH adsorption and facilitates the electrochemical conversion of CO2 to CO.

Mechanical and Light Activation of Materials for Chemical Production

Advanced Materials, EarlyView.
The actuation of stomata—referring to their opening and closing—is crucial for photosynthesis because it regulates gas exchange and water balance. Here, it is investigated if this life‐like property could enhance the photocatalytic properties of soft materials.
