Materials are extracted based on their solubility in different menstrua (solvents), and the spectral subtraction of solvents allows for the identification of groups present in the extracted materials. Given here is an example of how broccoli sprout fractions with four different FTIR spectra were derived using four different silicone polymer menstrua.

Previously, the theory explaining emulsion behavior was based on the equilibrium contact angle of the particle at the interface; however, Vinothan N. Manoharan, PhD, and his team at Harvard believe the time allowed for the system to reach equilibrium and the force pushing the particle to the interface are equally as important.
