Figure 2

Contour plot showing the effect of independent variables on size. (a) Effect of various levels of homogenization speed and internal-external phase volume ratio on size when the levels of other variables are maintained at low levels. (b) Effect of various levels of homogenization speed and internal-external phase volume ratio on size when the levels of other variables are maintained at high levels. (c) Effect of various levels of PVA concentration and internal-external phase volume ratio on size when the levels of other variables are maintained at low levels. (d) Effect of various levels of PVA concentration and internal-external phase volume ratio on size when the levels of other variables are maintained at low levels.
