Low Critical Micelle Concentration Discrepancy between Theory and Experiment

open access: yesThe Journal of Physical Chemistry Letters, 2014
Experimental measurements for a variety of surfactants unexpectedly show that the critical micelle concentration (CMC) becomes constant with respect to increasing the size of the hydrophobic tail. This observation disagrees with theoretical models where it is expected to continue to decrease exponentially.

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems
The critical micelle concentration (CMC) is the key characterization of surfactants. To date, no method can yield sequential CMC measurements in an automated fashion.

On the morphology and corrosion behavior of Ni nanostructures electrodeposited in the presence of different surfactants [PDF]

open access: yesشیمی کاربردی روز, 2018
In this work, Ni nano structures with different surface morphology have been electrodeposited from the Waths bath using direct current (DC) and pulsed reverse current (PRC) techniques in the presence of three types of surfactants. CTAB, SDS, and Triton x-

Ultrasonic and Densitometric Characterization of Hyaluronan and its Interaction with Surfactant [PDF]

open access: yes, 2014
This disertation thesis is focused on the study of physico-chemical interactions of hyaluronan (with molecular weights from 10 to 1750 kDa) with cationic surfactants measured using uncommon technique named high resolution ultrasonic spectroscopy ...

Pretransitional behavior in a water-DDAB-5CB microemulsion close to the demixing transition. Evidence for intermicellar attraction mediated by paranematic fluctuations

open access: yes, 2005
We present a study of a water-in-oil microemulsion in which surfactant coated water nanodroplets are dispersed in the isotropic phase of the thermotropic liquid crystal 5CB. As the temperature is lowered below the isotropic to nematic phase transition of

Measurement of Critical Micelle Concentration (CMC)

open access: yes, 2021
The Critical Micelle Concentration (CMC) is the surfactant concentration above which the addition of a monomer leads to the formation of the first micelle. Above the CMC, monomers and micelles exist in dynamic equilibrium. Almost all physical properties of a surfactant solution exhibit a sharp concentration dependent discontinuity in the region of ...

Robust Superhydrophobic Brass Mesh with Electrodeposited Hydroxyapatite Coating for Versatile Applications

open access: yesMolecules, 2022
A robust superhydrophobic brass mesh was fabricated based on a low-energy surface and a roughness on the nano/micro-meter scale. It was carried out by the forming of hydroxyapatite (HP) coatings on its surface through a constant current electro ...

Kinetics of non-ionic surfactant adsorption at a fluid-fluid interface from a micellar solution [PDF]

open access: yes, 2005
The kinetics of non-ionic surfactant adsorption at a fluid-fluid interface from a micellar solution is considered theoretically. Our model takes into account the effect of micelle relaxation on the diffusion of the free surfactant molecules.
