S-Index Interpretation
The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.
What it means:
- A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
- The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
- It provides a single number to track your research data impact over time
Current S-Index: 0.0 (sum of 2 datasets Dataset Index scores)

NH3 is one of the most important chemical products but only made at 400-500 C and 150-300 bar conditions due to the stable N2 molecule. Here we have developed a Ru-CeO2 catalyst with high activity under 1-10 bar. Kinetic study reveals a H-assisted N2 dissociation mechanism, with a volcano-type activity dependence on the N2 activation barrier and the H2 adsorption strength. To validate such mechanism and volcano trends, we need to understand: 1) How the Ru d band centre determines the N2 activation behaviours; 2) Does the d band centre change along with reaction conditions; 3) How does N=NH* formed on Ru surface. Here we apply for an in situ Ru L3 edge vtc- RIXS study to follow the dynamics of Ru d band and identify Ru-N=NH under NH3 synthesis conditions. This study utilizes the uniqueness of the in situ tender RIXS capability at ID26. It is also a perfect synergy between in situ RIXS study and experimental kinetic models, which is the first of its kind for NH3 chemistry.
