DOI: 10.1039/d3sm00273j
Abstract: Switchable materials in general and CO2-switchable materials in particular are of great interest in environmental research. The replacement of common non-switchable materials (solutions, solvents, surfactants, etc.) with their switchable counterparts has a great potential to… read more here.

DOI: 10.1080/01932691.2018.1555482
Abstract: Abstract N,N-Dimethylcyclohexylamine—a switchable-hydrophilicity solvent, ethanol and water could be used to prepare a CO2-switchable surfactant-free microemulsion (SFME). The ternary phase diagram was used to investigate the phase behavior of SFME. The electrical conductivity measurement, UV-visible… read more here.
