Green Material for Refrigeration Identified
Scanning the original paper linked by _Microft and rmbryan, it looks like the pressures the researchers used were very high, 0.25-0.5GPa. Maybe someone with more domain-specific knowledge can answer this: are such high pressures actually practical? My understanding is that one of the reasons R-744 (CO2) is not more common is that it requires high pressures, which means specialized equipment. But the pressures involved here seem to be an order of magnitude higher even than required with R-744.
