Due to the non-polar nature of supercritical carbon dioxide, addition of 5% and 10% ethanol have been used as polar co-solvent to change polarity and increase solubility. 30 different Tilia L. extracts were investigated. The effect of a range of solvents, temperature, pressure and time on ti...
The perovskite was decomposed by most of the solvents studied due to their strong polarity and the dynamic equilibrium between bound and free ligands, leading to the degradation of Cs2AgBiBr6. In contrast, the perovskite showed superior stability in chloroform and octane for more than 3 weeks. ...
obtained by SC-SO2 with hexane extracts (solvents with similar polarity), and to compare the extracts obtained by SC-SO2 with EtOH extracts (solvents with different polarity) with respect to the extraction yields, coumarin content, DPPH scavenging capacity, and TPs content of the obtained extracts...
