Book excerpt: A systematic study of the structure and dynamics of nanoparticles (NP) and NP-surfactants was performed. The ligands attached to both the NPs and NP-surfactants dictate the manner in which the nanoscopic materials assemble at fluid interfaces. Studies have shown that a single layer of the nanoscpic materials form at the interface to reduce the interactions between the two immiscible fluids. The shape of the NP is, also, important, where for spherical particles, a disordered, liquid-like monolayer forms, and, for nanorods, ordered domains at the interface is found and, if the monolayers are compressed, the orientation of the nanorods with respect to the interface can change. By associating end-functionalized polymers to the NPs assembled at the interface, NP-surfactants are formed that increase the energetic gain in segregating each NP at the interface which allows the NP-surfactants to jam at the interface when compressed. This has opened the possibility of structuring the two liquids by freezing in shape changes of the liquids.

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to various aspects of self-assembly of gold nanoparticles at liquid-liquid interfaces and investigation of their properties. It covers primarily two large fields: (i) self-assembly of nanoparticles and optical properties of these assemblies; and (ii) the role of nanoparticles in redox electrocatalysis at liquid-liquid interfaces. The first part aroused from a long-lasting idea to manipulate adsorption of nanoparticles at liquid-liquid with an external electric field to form 'smart' mirrors and/or filters. Therefore, Chapters 3 to 5 are dedicated to explore fundamental aspects of charged nanoparticles self-assembly and to investigate optical properties (extinction and reflectance) in a through manner. Novel tetrathiafulvalene (TTF)-assisted method leads to self-assembly of nanoparticles into cm-scale nanofilms or, so-called, metal liquid-like droplets (MeLLDs) with remarkable optical properties. The second part (Chapters 6 to 8) clarifies the role of nanoparticles in interfacial electron transfer reactions. They demonstrate how nanoparticles are charged and discharged upon equilibration of Fermi levels with redox couples in solution and how it can be used to perform HER and ORR. Finally, Chapter 9 gives a perspective outlook, including applications of suggested methods in fast, one-step preparation of colloidosomes, SERS substrates as well as pioneer studies on so-called Marangony-type shutters drive by the electric field.

Available in PDF, EPUB and Kindle. Book excerpt: And, on the same time scale there is a concomitant decrease in the SAXS form factor from disordered nanoparticles. X-ray beam transmission at different vertical heights characterizes the heptane and DEG bulk and interfacial regions, while monitoring the time dependence of SAXS at and near the DEG/heptane interface gives a clear picture of the evolution of nanoparticle assembly at this liquid/liquid interface. These SAXS observations of self-limited nanoparticle monolayer formation at the DEG/heptane interface are consistent with those using the less direct method of real-time optical reflection monitoring of that interface.

This book was released on 2012 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembly is a fundamental mechanism by which structures form in materials. This mechanism has given rise to many new technological advances in applications as diverse as structural composites, medicine, alternative energy sources and information technology. Many current approaches to self-assembly have shown promise, but each has its own unique limitations. The over-arching goal of this study is to develop self-assembly processes for nanoparticles that are simple, scalable and cost effective. In this dissertation we examine the mechanism for self assembly of nanoparticles in dispersion and at fluid-fluid interfaces. A simple method is presented for the synthesis of amphiphilic gold nanoparticle surfactants that self-assemble into clusters of controllable structure. The technique is based on the control of particle clustering through sequential functionalization of the surface with thiol terminated polyethylene glycol to sterically stabilize particles in water and short alkane-thiols that render the particles amphiphilic. These nanoparticle surfactants are surface active and form rafts at the air-water interface and stable nanoparticle clusters in dispersion. The clusters are also reminiscent of traditional micelles with an adjustable aggregation number that is controlled via modification of the grafting density of polymer on the nanoparticle surface. The nanoparticle surfactants are also shown to be highly effective emulsifying agents due to their amphiphilicity and they adsorb strongly to oil-water interfaces with controllable inter-particle separation distances. Both the clusters and colloidosomes that can be formed with these particles exhibit tunable shifts in plasmon resonance, enhancing the near-infrared optical absorption and making them useful for a wide range of applications.

Book excerpt: Fluid interfaces are promising candidates for confining different types of materials, e.g., polymers, surfactants, colloids, and even small molecules, to be used in designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the physicochemical bases underlying the formation of layers at fluid interfaces as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and features of dynamics in the interfacial systems, which are far removed from those conventionally found in traditional materials. This Special Issue is devoted to studies on the fundamental and applied aspects of fluid interfaces, and attempts to provide a comprehensive perspective on the current status of the research field.

Book excerpt: Self-assembly of nanoparticles at the interface between two fluids, and methods to control such self-assembly process, e.g., the surface density of particles assembling at the interface; to utilize the assembled nanoparticles and their ligands in fabrication of capsules, where the elastic properties of the capsules can be varied from soft to tough; to develop capsules with well-defined porosities for ultimate use as delivery systems; and to develop chemistries whereby multiple ligands or ligands with multiple functionalities can be attached to the nanoparticles to promote the interfacial segregation and assembly of the nanoparticles. Certain embodiments use cadmium selenide (CdSe) nanoparticles, since the photoluminescence of the particles provides a convenient means by which the spatial location and organization of the particles can be probed. However, the systems and methodologies presented here are general and can, with suitable modification of the chemistries, be adapted to any type of nanoparticle.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date technological applications of liquid crystal (LC)-based devices have relied on the nematic LC materials in the form of drops or emulsions stabilized by surfactants. Adsorption of nanoparticles at liquid interfaces results in emulsions with exceptional stability. Adsorption of nanoparticles at nematic liquid crystal interfaces provides an alternative promising approach to stabilize nematic emulsions or drops. Improved understanding of the dynamics of the adsorption process of nanoparticles at the nematic LC-water interface is important not only due to its technological significance, but also of interest for the fundamental understanding of non-uniform, ordered fluids. In this work, the dynamic adsorption process of ethyl-cellulose (EC) (with an average radius of 44nm) nanoparticles at the nematic liquid crystal 4-cyano-4'-pentylbiphenyl (5CB) interface is studied by measuring dynamic interfacial tension with the use of a pendant drop tensiometer. Analysis of the dynamic interfacial tension in terms of a model developed by Bizmark et al. (2014) provides information on the adsorption energy of EC nanoparticles that is compared to the adsorption energy values obtained from two other approaches. We conclude that Bizmark's model for the irreversible adsorption is valid for EC nanoparticle at the isotropic fluid interfaces and also can be applied to study the adsorption of nanoparticles at a nematic liquid crystal interface. Additionally, a model is derived to approximately probe the transient surface (interface) coverage of nanoparticles adsorbed at LC-water interface. Polarized microscopy analysis of 5CB confined between two EC-treated glass substrates confirms that adsorption of EC nanoparticles has no effect on the alignment of 5CB molecules at the interface.

Book excerpt: All of us have read about the vast potential inherent in nanotechnology and the exciting impact it has had in changing our lifestyle in the 21st century. One of the basic issues confronting us is how to fabricate devices or materials on the nano scale. What is the basic physics governing the formation of nano phases? How can biological systems inspire us to formulate nano scale architectures, in the way nature has always done and continues to do? These are two main areas of focus in this book. The aim of this reference is to take us to the root of these issues: the solid-fluid interfacial structures and the basic interactions between structural units that determine the kinetics of nano particles and assembly formation, and subsequently the resulting structures and functionalities of the nano phases and devices. By taking a fresh look at the novel nano structure engineering and surface probing technologies from a global viewpoint of fundamental principles, the two volumes of this book direct our focus from the macroscopic phase to the nano structures ranging from inorganic to bio nano materials. Featuring contributions from a number of international experts in the related fields, this book offers a comprehensive and synergistic look into these challenging issues in terms of theoretical modeling, computer simulations, advanced surface probing and fabrication and interface characterizations. The book also provides a link to the nanostructure engineering of some novel materials playing an important role in advancing technologies in this field.
