1. Accounting for optical errors in microtensiometry

Author:

Subject:
image analysis; models; surface tension
Abstract:
... Drop shape analysis (DSA) techniques measure interfacial tension subject to error in image analysis and the optical system. While considerable efforts have been made to minimize image analysis errors, very little work has treated optical errors. There are two main sources of error when considering the optical system: the angle of misalignment and the choice of focal plane. Due to the convoluted na ...

Abstract:
... The design of surfactants for CO2/oil emulsions has been elusive given the low CO2-oil interfacial tension, and consequently, low driving force for surfactant adsorption. Our hypothesis is that waterless, high pressure CO2/oil emulsions can be stabilized by hydrophobic comb polymer surfactants that adsorb at the interface and sterically stabilize the CO2 droplets. The emulsions were formed by mixi ...
