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 1 dataset Dataset Index scores)

Datasets
Here we propose to use Bragg coherent diffraction imaging (BCDI) to investigate diffusion barriers forming during the hydrogen gas reduction of small crystals of hematite and magnetite undergoing the “Steam-Iron” reaction. We will examine well characterised 300 nm grown crystals of hematite (Fe2O3) and micron-sized FIB-cut samples of magnetite (Fe3O4) in a heater cell under flows of dilute H2 gas or H2O in reverse. We will use the strain sensitivity of BCDI to obtain 3D images of strain in situ during the reaction. Both directions of the reaction show kinetic blockages in the reaction rate, attributed to the formation of defects of unknown nature. We aim to understand the role of crystal defects in the reaction rate and cycling stability of the reaction, the interconversion of iron oxides and iron metal by the interaction of hydrogen and gaseous water. This addresses two overlapping planet-care goals, hydrogen storage and carbon-free steelmaking to reduce global CO2 emissions.
