Book excerpt: Complex emulsions are dispersions of kinetically stabilized multiphasic emulsion droplets comprised of two or more immiscible liquids that provide a novel material platform for the generation of active and dynamic soft materials. In recent years, the intrinsic reconfigurable morphological behavior of complex emulsions, which can be attributed to the unique force equilibrium between the interfacial tensions acting at the various interfaces, has become of fundamental and applied interest. As such, particularly biphasic Janus droplets have been investigated as structural templates for the generation of anisotropic precision objects, dynamic optical elements or as transducers and signal amplifiers in chemo- and bio-sensing applications. In the present thesis, switchable internal morphological responses of complex droplets triggered by stimuli-induced alterations of the balance of interfacial tensions have been explored as a universal building block for the design of multiresponsive, active, and adaptive liquid colloidal systems.

Download or read book Multiresponsive Behavior of Biomembranes and Giant Vesicles written by and published by Academic Press. This book was released on 2019-11-27 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomembranes consist of molecular bilayers with many lipid and protein components. The fluidity of these bilayers allows them to respond to different environmental cues by changing their local molecular composition as well as their shape and topology. On the nanometer scale, this multi-responsive behavior can be studied by molecular dynamics simulations, which provide both snapshots and movies of the bilayer conformations. The general conceptual framework for these simulations is provided by the theory of curvature elasticity. The latter theory also explains the behavior of giant vesicles as observed by optical microscopy on the micrometer scale. The present volume describes new insights as obtained from recent developments in analytical theory, computer simulations, and experimental approaches. The seven chapters of the volume are arranged in a bottom-up manner from smaller to larger scales. These chapters address the refined molecular dynamics and multiscale modeling of biomembranes, their morphological complexity and adhesion, the engulfment and endocytosis of nanoparticles, the fusion of giant unilamellar vesicles, as well as recent advances in microfluidic technology applied to model membranes. Bridging the gap between lipid molecules and giant unilamellar vesicles (GUVs) Integrated view obtained from analytical theory, computer simulations, and experimental observations Multiresponsive behavior and morphological complexity of biomembranes

This book was released on 2020 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis summarizes the use of interfacial reactions, responsive surfactants, and specific tuning of interfacial tensions to discover novel ways to manufacture and manipulate dynamic double emulsion systems. In Chapter 1, we introduce emulsions and surfactants. We describe the fabrication of emulsions and creating stimuli responsive systems. Finally, we explore the relatively recent research into dynamic double emulsions, which is explored further in this thesis. In Chapter 2, we demonstrate the use of selective, interfacial imine formation at emulsion interfaces for the in situ formation of surfactants for novel manufacturing of emulsions and biosensors, dynamic morphology changes through perturbing imine equilibria, and the destruction of emulsions with imine formation at the emulsion-solid interface. In Chapter 3, we introduce surfactants that localize at the internal interface of double emulsions, which enables the incorporation of liquid crystals into dynamically reconfigurable complex emulsions. Further, we demonstrate that isomerization of a photo-responsive azobenzene surfactant at the internal interface of liquid crystal double emulsions results in reversible morphology change. In addition, isomerization of the azobenzene internal surfactant results in overall droplet movement, both orientational and translational. In Chapter 4, we describe that interfacial confinement of magnetic nanoparticles to emulsions interfaces, accomplished through interfacial imine formation, imparts ferromagnetic behavior to dynamic double emulsion comprising isotropic solvents. Further, we demonstrate liquid crystal double emulsions enable precise assembly of magnetic nanoparticles at the emulsion interface and can produce droplets movement and reorganization of the director field. In Chapter 5, we synthesize nucleophile-responsive surfactants with Michael acceptor functionalities to create responsive single and double emulsions. We demonstrate the emulsion systems are responsive to both small nucleophiles and polymeric nanoassemblies. Further, we describe the use of an unrelated stimuli, light, to trigger a cascade that results in emulsion responses.

Download or read book Emulsion Science written by Jerôme Bibette and published by Springer. This book was released on 2003-07-01 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceuticals, paints and oil industries. As end products, emulsions allow to avoid organic solvent in processing hydrophobic coatings. Emulsion technology is a suitable approach to vehicle viscous phases. It is also a remarkable mean of targeting actives or capturing specific species. The range of applications of emulsions progresses and their manufacturing becomes more and more sophisticated. Besides this broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physic and chem istry. Indeed, as a class of soft colloidal materials, emulsions science is linked to various aspects of these disciplines: phase transitions, surface forces and wetting, metastability and hydrodynamic instabilities, mechanical properties and flow. The aim of this book is to review the main important concepts governing emulsion science. In Chapter 2, repulsive interactions between liquid films are discussed as well as adhesive interaction related to wetting. In Chap ter 3, consequences of weak and strong attractions are presented, related to the well accepted liquid solid transition analogy. In Chapter 4, the basics of both bulk compressibility and shear elasticity are presented, the role of disorder being the most important aspect of the elastic behavior of these soft systems. In Chapter 5 the central question of the emulsion lifetime related to metastability is discussed.

Download or read book Metallo Supramolecular Polymers written by Masayoshi Higuchi and published by Springer Nature. This book was released on 2019-11-12 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the synthesis, electrochemical and photochemical properties, and device applications of metallo-supramolecular polymers, new kinds of polymers synthesized by the complexation of metal ions and organic ditopic ligands. Their electrochemical and photochemical properties are also interesting and much different from conventional organic polymers. The properties come from the electronic intra-chain interaction between the metal ions and the ligands in the polymer chain. In this book, for example, the electrochromism that the Fe(II)-based metallo-supramolecular polymer exhibits is described: the blue color of the polymer film disappears by the electrochemical oxidation of Fe(II) ions to Fe(III) and the colorless film becomes blue again by the electrochemical reduction of Fe(III) to Fe(II). The electrochromism is explained by the disappearance/appearance of the metal-to-ligand charge transfer absorption. The electrochromic properties are applicable to display devices such as electronic paper and smart windows.
