A Simple Micellar Gold Catalyst Supported by a Hydrophilic Phosphinoferrocene Amidosulfonate Ligand

European Journal of Inorganic Chemistry, EarlyView.
A phosphinoferrocene amidosulfonate and its chlorogold complex form micelles in water. The complex can be used as a self‐activating Au catalyst, as demonstrated for the model cyclization of N‐propargyl benzamide into 4,5‐dihydro‐5‐methylene‐2‐phenyloxazole.

Evaluating the Impact of Phosphate‐Buffered Saline Solutions on the Micellar Behavior of Dimeric Surfactants and Their Interaction With Lipid Membranes

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT Over the past few years, dicationic alkylammonium bromide dimeric surfactants have emerged as promising agents for numerous biotechnology and medical applications. However, there have been few studies examining their behavior within a biological context, particularly regarding the impact physiological buffers have on their physico‐chemical ...

Enhanced oil recovery by nonionic surfactants considering micellization, surface, and foaming properties

Petroleum Science, 2017
Surfactants for enhanced oil recovery are important to study due to their special characteristics like foam generation, lowering interfacial tension between oleic and aqueous phases, and wettability alteration of reservoir rock surfaces.

Micellization and mixed micellization of alkylxylenesulfonates — a calorimetric study

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract The effects of the position of sulfonate and of methyl groups on the aromatic ring of isomerically pure alkylxylenesulfonates on micellization and mixed micellization have been investigated using microcalorimetry and surface tension measurements.

Effect of Propylene–Oxide Segment Length on Cleansing Performance of Detergents With Nonionic Surfactants

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT Understanding the relationship between surfactant molecular structure and cleansing performance is essential for the rational design of high‐performance detergents. In this study, we investigate the effect of propylene oxide (PO) chain length on the detergency of nonionic surfactants through a combination of experimental measurements and ...

Thermodynamic and Interfacial Characterization of Petroleum Industry Surfactants: A Study on Critical Micelle Concentration and Interfacial Tension Behavior under Mild Conditions

ChemistryOpen, EarlyView.
The interfacial and thermodynamic properties of five petroleum industry surfactants are evaluated under mild conditions. Interfacial tension is measured using spinning drop tensiometry, and critical micelle concentrations are determined conductometrically.

N‐Geranylated Amino Acid Surfactants with Low Critical Micelle Concentrations from Abundant, Naturally Derived Starting Materials

ChemistryOpen, EarlyView.
Cleaning Up Surfactants: Realising critical micelle concentrations lower than sodium dodecyl sulfate with sustainable surfactants prepared from amino acids and naturally occurring aldehydes. In this work, a simple method for the preparation of N‐alkylated amino acid surfactants in 1–2 steps is reported.
