This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid nanomaterials offer the combination of individual properties of different types of nanoparticles. Some strategies for the development of new nanostructures in larger scale rely on the self-assembly of nanoparticles as a bottom-up approach. The use of templates provides ordered assemblies in defined patterns. In a typical soft-template, nanoparticles and other surface-active agents are incorporated into non-miscible liquids. The resulting self-organized dispersions will mediate nanoparticle interactions to control the subsequent self-assembly. Especially interactions between nanoparticles of very different dispersibility and functionality can be directed at a liquid-liquid interface. In this project, water-in-oil microemulsions were formulated from quasi-ternary mixtures with Aerosol-OT as surfactant. Oleyl-capped superparamagnetic iron oxide and/or silver nanoparticles were incorporated in the continuous organic phase, while polyethyleneimine-stabilized gold nanoparticles were confined in the dispersed water droplets.

Available in PDF, EPUB and Kindle. Book excerpt: Microemulsions: Theory and Practice covers the development of the theory and practice of microemulsion systems. This book is divided into seven chapters that explore the physics and chemistry of microemulsions. This book deals first with the commercial history of microemulsions, from the discovery of carnauba wax emulsions to polymer emulsions. This topic is followed by discussions on the theoretical aspects of microemulsion formulation techniques and the design of other products. The subsequent chapter describes the microemulsion formulation with less solubilizer or emulsifier together with their optical properties. A chapter examines the mixed film theory that explains the dispersions, oil-water interface, and inferences in microemulsions. Another chapter considers the role of microemulsions in micellar solutions and their relations to the concentrations of different compounds. This chapter also looks into the association phenomena of three-component phase equilibria diagrams and liquids crystals to microemulsions. The concluding chapter discusses the role of the capillary and hydrostatic forces on the entrapment of oil in the reservoir and the necessary conditions for the displacement of entrapped oil. The important properties and economic aspects of a microemulsion slug required for the tertiary oil recovery are also covered in this chapter.

Book Synopsis Ethyl Cellulose Nanoparticles in Multiphase Systems by : Navid Bizmark
Download or read book Ethyl Cellulose Nanoparticles in Multiphase Systems written by Navid Bizmark and published by . This book was released on 2017 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption-mediated self-assembly of ethyl cellulose (EC) nanoparticles at fluid interfaces, driven by reduction in interfacial energy, is shown to lead to stabilization of emulsions and foams. A multiscale approach is followed to address a number of fundamental and practical questions for application of EC nanoparticles in multiphase flows through porous media. At the nanoscale, the effects of pair interactions between EC nanoparticles suspended in water, between an EC nanoparticle and a fluid interface (oil-water or air-water), and between EC nanoparticles adsorbed at a fluid interface are studied by extended-DLVO computations and dynamic surface (interfacial) tension measurements with emphasis on - the dependence of colloidal suspension stability on ionic strength - the kinetics of nanoparticle adsorption at the air-water and alkane-water interfaces - the nature and extent of coverage of fluid interfaces by nanoparticles In the absence of salt, EC nanoparticle suspensions are stable at neutral pH as a result of electrostatic repulsion, but colloidal stability is lost by the addition of salt at or beyond a concentration of 0.05 M (the critical coagulation concentration or CCC). Regardless of ionic strength, however, hydrophobic attraction dominates the interactions between EC nanoparticles and fluid interfaces, resulting in barrier-less irreversible adsorption at both the air-water and alkane-water interfaces. Ionic strength is also found to have insignificant effect on the coverage of either kind of interface at steady-state, which approaches the jamming limit of 91% corresponding to a tight hexagonal packing for any value of the ionic strength in the range of 0 M to 0.1 M. Nonetheless, subtle effects of the ionic strength are observed on the rate of approach to steady state, during the later stages of adsorption, which is accelerated by the addition of salt in the case of the alkane-water interface, but apparently unaffected in the case of the air-water interface. Above the CCC, alkane-water and air-water interfaces behave similarly, in that the approach to steady state is decelerated as a result of increased surface blocking and competition for adsorbing species between coagulation in the bulk and attachment at the interface. These findings lead to new insights into the way in which EC nanoparticles stabilize emulsions and foams. The extent to which EC nanoparticles may be used to stabilize so-called Pickering emulsions is investigated as a function of phase volume ratio, ionic strength and nanoparticle concentration. Both oil-in-water (O/W) and water-in-oil (W/O) Pickering emulsions are observed, their stability is quantified and explained theoretically. The most stable O/W Pickering emulsion is obtained at an ionic strength slightly below the CCC with at least 70% volume fraction for the internal phase, an observation which opens the path for the utilization of EC nanoparticles as stabilizers of high internal phase Pickering emulsions (HIPPE). Such a HIPPE is shown to act as a template to fabricate a polymeric porous material made of EC. This material is demonstrated to selectively adsorb oil from the surface of water, suggesting potential applications in the field of oil-water separations. In line with theoretical expectation, flow and transport tests in transparent glass micromodels demonstrate that EC nanoparticles in stable colloidal suspensions (i.e., below CCC) move through silica-based porous media as a conservative tracer (e.g. NaCl). The convection-dispersion equation adequately describes this process with transport parameter (dispersivity and dispersion coefficient) values which agree with established models. Above the CCC convection accelerates the coagulation of EC nanoparticles, resulting in very rapid clogging of the porous medium and effective filtration of the nanoparticles. Lastly, it is demonstrated that foam can be generated in situ during the co-injection of gas and EC nanoparticle suspensions in glass micromodels, suggesting the possibility to engineer new foam flooding technologies for the recovery of hydrocarbons from subsurface porous media.

Download or read book Metallic Nanoparticles written by and published by Elsevier. This book was released on 2008-11-21 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallic nanoparticles display fascinating properties that are quite different from those of individual atoms, surfaces or bulk rmaterials. They are a focus of interest for fundamental science and, because of their huge potential in nanotechnology, they are the subject of intense research effort in a range of disciplines. Applications, or potential applications, are diverse and interdisciplinary. They include, for example, use in biochemistry, in catalysis and as chemical and biological sensors, as systems for nanoelectronics and nanostructured magnetism (e.g. data storage devices), where the drive for further miniaturization provides tremendous technological challenges and, in medicine, there is interest in their potential as agents for drug delivery.The book describes the structure of metallic nanoparticles, the experimental and theoretical techniques by which this is determined, and the models employed to facilitate understanding. The various methods for the production of nanoparticles are outlined. It surveys the properties of clusters and the methods of characterisation, such as photoionization, optical spectroscopy, chemical reactivity and magnetic behaviour, and discusses element-specific information that can be extracted by synchrotron-based techniques such as EXAFS, XMCD and XMLD. The properties of clusters can vary depending on whether they are free, deposited on a surface or embedded in a matrix of another material; these issues are explored. Clusters on a surface can be formed by the diffusion and aggregation of atoms; ways of modelling these processes are described. Finally we look at nanotechnology and examine the science behind the potential of metallic nanoparticles in chemical synthesis, catalysis, the magnetic separation of biomolecules, the detection of DNA, the controlled release of molecules and their relevance to data storage.The book addresses a wide audience. There was a huge development of the subject beginning in the mid-1980s where researchers began to study the properties of free nanoparticle and models were developed to describe the observations. The newcomer is introduced to the established models and techniques of the field without the need to refer to other sources to make the material accessible. It then takes the reader through to the latest research and provides a comprehensive list of references for those who wish to pursue particular aspects in more detail.
