Laboratory experiments from ENVIDAT present data on phase change at the surface of sodium chloride-water mixtures. The dataset includes near-edge X-ray absorption fine structure (NEXAFS) spectra of hydrohalite, collected between 259 K and 240 K. The data was published via NASA Earthdata and last updated in 2020.
Use Cases
- Analyzing the NEXAFS spectrum of hydrohalite to identify its chemical signature at the frozen interface.
- Modeling phase change behavior using temperature data points between 259 K and 240 K.
- Studying interfacial supercooling dynamics from surface-selective electron yield NEXAFS measurements.
- Correlating temperature with the precipitation of hydrohalite in sodium chloride solutions.
Strengths
- Data provides high selectivity to the upper few nanometres of the frozen solution-air interface.
- Experiments cover a controlled temperature range from 259 K down to 240 K.
Limitations
- Sample size and number of experimental runs are unknown.
- The dataset's specific features, such as column names and row counts, are not provided.
