Langevin studies liquid interfaces and
interfacial rheology, the flow of matter at interfaces between liquids, or between a liquid and a gas. She is particularly interested in foams and emulsions and has made significant contributions relating the mechanical properties of interfaces to the stability of foams and emulsions. She has had a major role in bringing together scientists and mathematicians from multiple disciplines to develop the field of foam and emulsion science.[5] Her books include Light Scattering by Liquid Surfaces and Complementary Techniques (1992)[6] and Emulsions, microemulsions and foams (2020).[7]
Early life
The daughter of Maurice Cruchon and Jacqueline Maujean, she was born Dominique Anne-Marie Cruchon in
Angoulême. In 1969, she married Michel Langevin.[1]
During the 1970s, Langevin established the
surfactant group at the École Normale Supérieure. During the early 1990s, she established the "Films de tensioactifs flexibles" research group. From 1994 to 1998, Langevin was director of the Centre de Recherche Paul Pascal in
Bordeaux.[10][9] She was president of the European Colloid and Interface Society from 1992 to 1993.[8]
Research
Her areas of research have included the experimental study of
soft matter physics, including the surface of
liquid crystals, mixtures of
surfactants and
polymers, the effects of nanoparticles on foams, foam drainage and soap film drainage, and the
surface rheology of ultralow tension surfactant-oil-water systems.[8][9][11][12][13]
Langevin has made significant contributions relating the mechanical properties of interfaces to the stability of foams and emulsions. Her work has broad application in industry and medicine, relating to preparation of foods and medicines, detergents, construction materials, fire-fighting, mineral extraction, recovery of pollutants, and nuclear waste treatment.[5]
She has also worked with the European Space Agency (ESA), leading an international team to study the behavior of foams in
microgravity, in the FOAM-C (Foam and Optics Mechanics–Coarsening) experiment.[4][14]
Awards
Langevin has received awards including:
2012, Kasha Mittala (Kash Mittal Award) for Surfactant in Solution Science[15]
