Figure 2.

Microstructural analysis. (a, b) Representative SEM images for the cross section of the spheroidal droplets. (c, d) Representative SEM images for the cross-sectional structures of the flattened disk structure (control). (e) Graph depicting average pore diameter of the spheroidal droplet in comparison to the control structure. At least 5 representative images were acquired for analysis to generate the data in (e). Average pore diameter was found to be statistically different (^∗p < 0.05) between the spheroidal droplet and control samples.
