Specific Ion Effects of Dodecyl Sulfate Surfactants with Alkali Ions at the Air–Water Interface

Molecules, 2019
The influence of Li+, Na+ and Cs+ cations on the surface excess and structure of dodecyl sulfate (DS−) anions at the air−water interface was investigated with the vibrational sum-frequency generation (SFG) and surface tensiometry ...

Characterization of Structure-Surface Correlations in Ointments Using Surface Tensiometry within the Concept of an Integrated Analytical Approach

Langmuir
In recent years, integrated data analysis has proven to be a valuable method for investigating complex systems, whether artificial or natural. The integrated analytical approach allows the simultaneous integration of data acquired from different analytical techniques employed for the same sample at the same time, leading to an expansion of the amount ...

Generalized surface momentum balances for the analysis of surface dilatational data [PDF]

, 2018
Dilatational rheological properties of interfaces are often determined using drop tensiometers, in which the interface of the droplet is subjected to oscillatory area changes.

Collapsed bipolar glycolipids at the air/water interface: Effect of the stereochemistry on the stretched/bent conformations.

, 2013
International audienceThis article describes a comparative study of several bipolar lipids derived from tetraether structures. The sole structural difference between the main two glycolipids is a unique stereochemical variation on a cyclopentyl ring ...

Enhancing biosensor capabilities through laccase immobilization in nanostructured Langmuir-Blodgett films for phenol detection

Results in Surfaces and Interfaces
Fabricating nanoscale structures combining various elements with specific functionalities is a pertinent strategy for enhancing sensor capabilities. In this study, we immobilized Laccase (Lac) in a biomimetic environment provided by a nanostructured ...

Light-absorbing secondary organic material formed by glyoxal in aqueous aerosol mimics [PDF]

Atmospheric Chemistry and Physics, 2009
Light-absorbing and high-molecular-weight secondary organic products were observed to result from the reaction of glyoxal in mildly acidic (pH=4) aqueous inorganic salt solutions mimicking aqueous tropospheric aerosol particles.
