Characterisation of water sorption cycle in hydrates of controlled oxide composition
ESR: Monisha Rastogi
Host: HTC (PhD awarded by EPFL)
Start date: January 1, 2018
The objective is
- To characterise the first two cycles of hydrate drying, rewetting and subsequent storage by Maruyama’s length change method, by gravimetric uptake and by environmental scanning electron microscopy to augment and cross check against the 1H analyses in Projects 4 and 5.
Progress of the project
