Dominique Langevin Festschrift: Four decades opening gates in Colloid and Interface Science
At the occasion of her 70th Birthday, the Special Issue “Dominique Langevin Festschrift” of Advances in Colloid and Interface Science in tribute to her research work, collects reviewing contributions from the main actors of these more than 40 years of indefatigable research in interface and colloid science.
Honorary note
Dominique Langevin was born July 24th, 1947. In 1974, she obtains her PhD and after one year in the laboratory of Pierre-Gilles de Gennes as a research associate, she starts a meteoric scientific career in colloid and interface science, opening new fundamental and applied problems, delivering new experimental methods, inspiring theoretical research and driving a new avenue of work developed by herself, her direct disciples and her extensive network of collaborators, in France, Europe and abroad. Her work also influences other prominent researchers who develop research in parallel to Dominique, in a highly competitive activity, strongly invigorated by the development of new and powerful experimental tools to study the structure and the dynamics of fluid interfaces and colloidal systems.
In 1974, Dominique Langevin defended her PhD with a doctoral thesis on the physical theory of the scattering of light by fluid surfaces [1]. With an impressive work supervised by Marie-Anne Bouchiat, Dominique presented groundbreaking experiments of scattering of light with liquid crystals [2], free liquid surfaces [3] and monomolecular films spread on [4], which were paving the way for the completion of the optical theory of scattering by structured liquid interfaces [5,6]. Those pioneering achievements in the use of optical methods to probe surface hydrodynamics were opening, perhaps unexpectedly for Dominique by those days, although promptly exploited in different aspects [7,8], a nascent field of research on the dynamics of fluid interfaces. The new field was fostered by Dominique, who recalling on the shoulders of B. Levich, F.C. Goodrich and D.T. Wasan, the old masters of physicochemical hydrodynamics, contributed to plant the fertile garden of fluid surfaces. During that Early Age of surface hydrodynamics, from the 1970′s till the mid 80′s, the hard work of Dominique Langevin, in tight collaboration with the vigorous community of soft matter in France, bears fruit in this garden [9,10,11,12,13]. During those young years, Dominique contributed to found the fruitful area of surface rheology; Dominique, a woman who was pioneer among equals, contributed to forge this science alongside her contemporary colleagues, J. Lucassen, M. van den Tempel, J.A. Mann, H. Yu, R.W. Richards, and the unfortunate J.C. Earnshaw, who died far too young but gave his best to the science that he had helped to create. After those pioneers, the field was further boosted by a large community that made the topic to become a mature art that has contributed to expand the field of surface rheology in different domains, from the dynamics of adsorbed layers of soluble surfactants, proteins and polymers, and insoluble films of natural lipids and synthetic polymers, up to the stability of colloids, biocolloids, structured fluids, and many other systems involving fluid interfaces in soft matter. Less than 20 years of intense research were sufficient for that pioneering community to build the doctrinal knowledge on the dynamics of fluid interfaces, a research area that was already reviewed in 1991, in a book edited by D. Langevin, that was entitled “Light Scattering by Liquid Surfaces and Complementary Techniques” [14]; today, a classical manual of indispensable reading for any beginner in this area; also, a

Dominique Langevin Festschrift: Four decades opening gates in Colloid and Interface Science
reference work for advanced experts in the experimental physics of fluid interfaces. From the early 1980′s, Dominique became already interested in different physical problems in soft matter involving fluid interfaces, from the dynamics of oil-water interfaces that leads to the stability of microemulsions [15], and its critical behavior [16], to surface-related aspects of the criticality of micellar systems [17], the rheology of insoluble films of fatty compounds [18] and polymers [19], and the dynamics of concentrated solutions with structured colloids [20]. By the late 1980′s, Dominique was already a renowned personality in the field of fluid interfaces, somebody that was entirely willing to assault new challenging enterprises, in much more complex fields: The physics of emulsions and foams. The time for researching the physics of those complex colloids was arrived, and Dominique started by endowing her lab with new tools to explore interfacial dynamics, first with a PhD thesis on the viscoelasticity of adsorption layers of soluble surfactants using electrocapillary excited waves [21], and immediately next with new methods to address the by then open question of the role of bending elasticity on the stability of microemulsion systems [22,23], today a crucial topic in biological physics by its impact on membrane biophysics. At the beginning of the 1990s, D. Langevin was worldwide recognized not only as a specialist scholar on the interfacial dynamics of the stabilizing surfactant layers of microemulsions [24,25,26,27], but also the expert of reference on the experimental tools to probe dynamics at complex fluid interfaces [14,28]. In that époque, Dominique became interested in the meta-stability of emulsions and foams, and her focus shifted to liquid films, inaugurating the new research line with the insightful PhD Thesis of Annie Bonfillon-Colin, on the role of surface viscoelasticity in the drainage of soap films [29,30], which became the starting point for a fruitful research on microemulsions [31], emulsions [32] and foams [33,34,35]. During this mature age of her scientific career mostly devoted to colloids, with emphasis on the physics of foams and emulsions, Dominique cultivated an exquisite manner to do research in soft matter, she developed a special charisma as a top scientist in the physics, and the physical chemistry of colloids and interfaces, a charm that attracted a large number of students and young talents. From the mid 1990′s, first in Bordeaux in the Centre de Recherche Paul Pascal and later, from the 2000s, in the Laboratoire de Physiques des Solides at Orsay campus, leading always numerous but especially insightful and vigorous research teams, Dominique Langevin developed an intense research on the physics of emulsions and foams, with a special emphasis on the stabilizing role of liquid films and the viscoelasticity of the fluid interfaces [36–39]. Other related problems have been also on the broad spectra of scientific interests of Dominique, having done insightful contributions on the spreading kinetics of polymer films [40], the surface hydrodynamics of soft gels [41], the kinetics of polymer stratification under confinement [42], the physics of polymer films [43,44], the unusual behavior of foams under non-gravity conditions [45], the surface rheology of lipid monolayers in relation with the fluidity of biomembranes [46], the critical cooperative dynamics of bubble rafts [47], and the dynamics of particle sedimentation [48], most of these works having been contributed in the last few years. It would be impossible solely mentioning a few papers to depict this Golden Age of the scientific career of Dominique: All of her research has been insightful on these problems; all of her scientific production has been relevant for these topics. Suffice to look at her impressive scientific biography, and the deep, long, large and intense research merits gathered by Dominique during these years [https://en.wikipedia.org/ wiki/Dominique_Langevin]. Today, more than four decades after her doctorate, after an intense professional life of scientific research in different fields of the physics of fluid surfaces, Dominique Langevin is absolutely one of the most prolific scientists in the domain of soft matter, having boosted tens of topics in colloid and interface science, with plenty of influential papers in her personal credit, and having parented an influential school of disciples who have spread worldwide, and over several generations of
scientists, her very personal manner of thinking and making science. But apart her tangible track record, impressive and influential at time, above all, Dominique is a visionary, an insightful scientist, extraordinarily intuitive, endowed with an outstanding creativity; somebody that has lived, along and across her scientific career, incessantly opening gates towards new paramount panoramas in science. Gates opened towards unexplored scientific landscapes, pictured in very fertile research fields, which Dominique has first cultured with extreme care to later fruitfully harvest. Landscapes that many others have later looked and walked, fields that have produced fruitful rewards to a big community of scientists working in colloid and interface science. A leitmotif impregnated those, already far but still current, Dominique's thesis: “The tandem theory-experiment, driven by the marriage between methodological rigour and creative intuition, understood as a perfect research performance for building beautiful science”. Dominique is extremely intuitive, but she never assumes anything. Dominique is insightfully creative, but she always questions everything. After discussing the results of any experiment, previously rationalized, carefully designed and scrupulously reviewed, Dominique always comes back to the very beginning with the theory that motivated the experiment, their consequences on the phenomenology involved, and the first principles that underlie their causes. The famous motto “Assume nothing, question everything”, quoted by James Patterson, an American writer and philanthropist born the same year as Dominique, has prevailed along the professional life of Dominique Langevin, surely also in all the other aspects of her personal life. Most probably Dominique has not personally known her contemporary, but this lemma has been word-byword the leitmotif that constantly recurred the professional activity of Dominique Langevin in all its facets. Such ethics has steered not only her praxis, but also flooded the laboratories by which she has passed, first in the doctoral years at the École Normale Superiere in Paris, later in the Collège de France during her postdoc with Pierre Gilles de Gennes, and from 1978, already as an independent researcher, first in the Laboratoire de Physique Statistique at ENS-Paris, later as the director of the Centre de Recherche Paul Pascal of CNRS in Bordeaux, and finally in the Laboratoire de Physique des Solides of the Université Paris-Sud in Orsay up today. For these last years, Dominique has made the Université Paris-Sud her home, where she has not only created a new lab on soft matter, which has performed very active research, but where Dominique has also engaged research teams that certainly will make to continue her research lines in colloids and surfaces, and to fruitfully culture the already doctrinal concepts that she helped establish in soft matter physics. After more than 40 years of scientific carrier, Dominique Langevin has contributed more than 15,000 days of incessant and tireless activity to research in soft matter science, published more than 350 research papers, edited two books, trained numerous students and postdocs, and mentored several generations of scientists that are today spread worldwide, occupying leadership positions in the best academic institutions and research centers in Europe, Asia and in the Americas. Dominique has chaired numerous scientific and academic committees in France, and served as an expert on different scientific instances and academic institutions in Europe and abroad. Along her scientific carrier, she has synthetized new concepts that have later boosted further advances in soft matter physics, and she has fostered the invention of novel methods, tools and instruments that have meant a step further in the analytic understanding of colloids and fluid interfaces. Dominique Langevin is an eminence in these fields, a very insightful and influential scientist in several research areas involving colloids and fluid interfaces of all types. She is indeed somebody who has definitely contributed to build the state-of the-art of Colloid and Interface Science as the mature discipline what we know nowadays. Today, the already senior scientists that constitute the Dominique's school -as we say familiarly, and the broad scientific community worldwide that has tightly collaborated with Dominique Langevin over these 40 years, strongly faithful with her legacy, at the occasion of her 70th Birthday, we feel the commitment to tribute her with this Dominique

After more than 40 years of scientific carrier, Dominique Langevin has contributed more than 15,000 days of incessant and tireless activity to research in soft matter science, published more than 350 research papers, edited two books, trained numerous students and postdocs, and mentored several generations of scientists that are today spread worldwide, occupying leadership positions in the best academic institutions and research centers in Europe, Asia and in the Americas. Dominique has chaired numerous scientific and academic committees in France, and served as an expert on different scientific instances and academic institutions in Europe and abroad. Along her scientific carrier, she has synthetized new concepts that have later boosted further advances in soft matter physics, and she has fostered the invention of novel methods, tools and instruments that have meant a step further in the analytic understanding of colloids and fluid interfaces. Dominique Langevin is an eminence in these fields, a very insightful and influential scientist in several research areas involving colloids and fluid interfaces of all types. She is indeed somebody who has definitely contributed to build the state-of the-art of Colloid and Interface Science as the mature discipline what we know nowadays. Today, the already senior scientists that constitute the Dominique's school -as we say familiarly, and the broad scientific community worldwide that has tightly collaborated with Dominique Langevin over these 40 years, strongly faithful with her legacy, at the occasion of her 70th Birthday, we feel the commitment to tribute her with this Dominique
