Bilayers with Surfactant-induced Pores and Demixing in Micelles : Studies of Segregation in Amphiphile Systems

, 2003
The focus of this thesis has been on the effects of segregation in mixtures of amphiphilic molecules. Two different systems were investigated: fluorocarbon-hydrocarbon surfactant mixtures and lipid-surfactant mixtures.

Study on foam extinguishing agent based on mixed system of branched short-chain fluorocarbon anionic and hydrocarbon cationic surfactants

, 2021
The traditional aqueous film-forming foam extinguishing agent (AFFF) plays an important role in fighting liquid fires, but its environmental hazard are also increasingly prominent.

The pyrolytic characterization of a surfactant/polymer/ceramic composite system using combined thermogravimetric analysis - mass spectrometry

, 1990
An experimental technique of combined thermogravimetric analysis (TGA)-mass spectrometry (MS) was used to study the pyrolysis process during binder removal from a ceramic/binder system. The effect of a fluorocarbon surfactant on the pyrolysis process was

Self-Assembly of a Fluorocarbon−Hydrocarbon Hybrid Surfactant: Dependence of Morphology on Surfactant Concentration and Time

, 2016
The morphologies of aggregates formed from a hybrid surfactant (F6H5OS) whose molecules have a hydrocarbon chain (pentyl group) and a fluorocarbon chain (perfluorohexyl group) were studied along with changes in the morphologies with time. F6H5OS exhibits

Fluorescence quenching studies of micellization and solubilization in fluorocarbon-hydrocarbon surfactant mixtures

, 1997
Time-resolved fluorescence quenching studies of nonionic, anionic, and cationic micelles have been performed to compare two surfactant quenchers, a fluorocarbon surfactant quencher, N-(1,1,2,2-tetrahydroperfluorodecanyl)pyridinium chloride (HFDePC) and ...

The state of fluorocarbon surfactant monolayers at the air-water interface and on Mica surfaces

, 1990
Monolayers of a cationic, double-chained fluorocarbon surfactant (N-(α-trimethylammonioacetyl)-O-O'-bis (1H, 1H, 2H, 2H-perfluorodecyl)-L-glutamate chloride) were studied at the air-water interface and adsorbed on the muscovite mica basal plane.

Study on the preparation and fire-extinguishing performance of a three-phase aqueous film-forming composite foam material stabilized by CeO

Case Studies in Thermal Engineering
To address the bottlenecks of insufficient long-term stability and poor fire resistance in traditional aqueous film-forming foam extinguishing agents, this study proposes a three-phase aqueous film-forming composite foam material stabilized by the ...

An unrecognized hazard of inhaled 6:2 FTOH: Pulmonary transformation and interfacial toxicity in the lung

Environment International
Evidence for the transformation of volatile fluorotelomer alcohols (FTOHs) after respiratory uptake remains elusive, and the role of their surface activity in health risk has been overlooked.
