Physiological compression–expansion cycles for SLS and vaping components. Results from CSD cycles run at up to 20 cycles per minute for 2 min. (A) SLS alone, first and last iso-cycles. (B) SLS with BA, first and last iso-cycles. (C) SLS with BPGA, first and last iso-cycles. BA and BPGA were added in a 1:10 molar ratio to surfactant lipids. (D) Comparison of the mean γmin of the first and last five cycles for each condition. (E) Temporal evolution of γmin covering all cycles of each condition represented. (F) Relative global compressibility of the first and last cycles, relative to the SLS first cycle. (G) Mean hysteresis of the first and last three cycles, relative to the SLS first cycle. Three independent replicates for each condition. Significance values represent results from a two-way ANOVA; “ns”: not significant (p > 0.05).
