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

ChemistryOpen
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.

Continental Patterns of Phenotypic Variation Along Replicated Urban Gradients: A Mega-Analysis. [PDF]

Ecol Lett
Using a mega‐analysis approach with long‐term data from 21 urban and nonurban great and blue tit populations, we introduce and test hypotheses to determine how urbanisation affects tarsus length and lay date variation at different population levels. We find that urbanisation is associated with increases in phenotypic variation within subpopulations by ...
