Synopsis

The macroscopic phenomenology of hydrophobicity - the segregation of oil and water - is well studied. However, its theoretical understanding in a molecular level is still incomplete. Recent progress in X-ray diffraction allowed for the first time to determine the structure of the oil/water interfaces with atomic resolution, yielding information on the molecular-scale origin of the hydrophobic interaction. Although bare oil/water interfaces occur only rarely, these interfaces are often decorated by surfactants, which modify the hydrophobic interaction. Oil/water interfaces, modified by non-ionic, electrically neutral, alcohol surfactants have been already studied. However, molecular resolution measurements for the more complex electrically-charged ionic surfactants are not available in the literature. Thus, a key ingredient in the fundamental understanding of the relation between ionic surfactants and the hydrophobic interactions is still missing. Here, we employ X-ray diffraction and surface tension techniques in order to investigate the structure and thermodynamics of these surfactant decorated oil/water interfaces and their hydrophobic interactions.

Biographie de l'auteur

Shai Yefet was born in Israel to an Orthodox Jewish family. In addition to traditional Judaism studies, he graduated his M.Sc. at Bar-Ilan University in Molecular Physics, focusing on phase transition and crystallization of thin films. He is now studding for Ph.D. in Quantum Optics, focusing on development of novel laser systems.
