(a) Profiles formed by cuts with three pixels width from the beam center along the vertical direction for the pure DPPC film under different relative humidities at 306 K. The first-order Bragg peaks are around Qz = 0.1 Å−1 and the second-order peak was around Qz = 0.2 Å−1. (b) Profiles formed by cuts with three pixels width from the beam center along the vertical direction for DPPC multibilayers inserted with β-amyloid peptide 1–40 under different relative humidities at 306 K. |
