Scale Size-Selective Fractionation

Therefore, the system is infinitely scalable if the time scale for C02 diffusion is acceptable or if the mass transport of CO2 into the liquid phase can be enhanced (e.g., bubbling the C02 directly into the liquid).

Saunders, S.R. and Roberts, C.B. (2009) Size-selective fractionation of nanoparticles at an application scale using C02 gas-expanded liquids. 

The insecticidal efficiency under laboratory conditions of various members of two series of narrow boiling petroleum fractions was determined for adult female California red scale, Aonidiella auranfii (Mask.) and eggs of the citrus red mite, Paratetranychus citri (McG.). Correlations between efficiency and various properties of the fractions such as structural character, molecular weight, and viscosity were observed. These correlations Indicate that conventional spray oils used on citrus in California may contain appreciable amounts of hydrocarbons of low insecticidal activity. The evidence indicates that the insecticidal efficiency of spray oils against citrus insect pests may be considerably improved by proper selection with respect to structural character and molecular size.
