From: Highly efficient enzymatic biodiesel production promoted by particle-induced emulsification
Emulsion pictures using different conditions. (A) No additive, (B) non-modified silica gel 35 to 70 μm, (C) non-modified silica gel 0.2 to 0.3 μm, (D) non-modified silica gel 0.007 μm, (E) phenyl silica gel 35 to 70 μm, (F) phenyl silica gel 0.2 to 0.3 μm, (G) phenyl silica gel 0.007 μm. Used was 4% w/v of the different additives and 100 μL of TLL/g substrate. Scale bars: 10 μm. The large structures in (B) and (E) are silica particles.
