Rheological investigation of self-emulsification process: effect of co-surfactant.
PURPOSE The aim of study is to investigate role of co-surfactant in self-emulsification through rheological analysis of intermediate liquid crystalline (LC) phase formed during self-emulsification. METHODS To mixture of Captex 200P (C200) and tween 80 (T80) (SES Plain), either medium hydrocarbon chain co-surfactant (Capmul MCM (CMCM): SES C) or long hydrocarbon chain co-surfactant (Peceol (P)...
متن کاملUltrasound Assisted Surfactant Enhanced Emulsification Microextraction and Spectrofluorimetry for Determination of Oxadiazon in Agricultural Water Samples
In this work, an environmentally friendly sample pre-treatment method, Ultrasound Assisted Surfactant Enhanced Emulsification Microextraction (UASEME) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. After the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfac...
متن کاملHighly clear and transparent nanoemulsion preparation under surfactant-free conditions using tandem acoustic emulsification.
A new technique for the preparation of a highly clear and transparent emulsified aqueous solution containing immiscible monomer droplets with diameters of a few tens of nanometres under surfactant-free conditions using tandem acoustic emulsification is described. Highly conductive transparent polymer films were successfully prepared from such an emulsified solution.
متن کاملVortex-assisted surfactant-enhanced emulsification microextraction based on solidification of floating organic drop followed by electrothermal atomic absorption spectrometry for speciation of antimony (ΙΙΙ, V).
Vortex-assisted surfactant-enhanced emulsification microextraction based on solidification of floating organic drop (VASEME-SFO) was used for preconcentration and speciation of antimony (ΙΙΙ, V) followed by electrothermal atomic absorption spectrometry (ETAAS). In this procedure, Triton X-114 was used as emulsifier and 1-undecanol was used as extraction solvent. This method is based on the comp...
متن کاملSoft lithography using acryloxy perfluoropolyether composite stamps.
This paper describes composite patterning elements that use a commercially available acryloxy perfluoropolyether (a-PFPE) in various soft lithographic techniques, including microcontact printing, nanotransfer printing, phase-shift optical lithography, proximity field nanopatterning, molecular scale soft nanoimprinting, and solvent assisted micromolding. The a-PFPE material, which is similar to ...
