Fig. 2

Compressive moduli of the foams with varying levels of concentration and in three different states. a shows the moduli of the foams in a dry state. b shows the moduli of the foams in a wet state. c shows the moduli of foams in a lyophilized state. Sample size of n = 3 and bars with * or ** indicates statistical significance of p < 0.05 or p < 0.01, respectively between the two foams. Significance was obtained using ANOVA and Tukey post hoc analysis
