Figure 2
Ice diffraction from glycerol–water mixtures at different concentrations and temperatures. The top row shows 2D diffraction patterns, all plotted with the same pixel count to greyscale calibration. The bottom row shows 1D diffraction patterns obtained from the 2D patterns by azimuthal averaging. The intensity scales of the 1D patterns are individually normalized. Similar trends are observed with other common cryoprotectants, including 2-methyl-2,4-pentanediol (MPD), sucrose and polypropylene glycol. |
