Abstract: The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed asphalt binder and mixture The rotational viscosity (RV), dynamic shear rheometer (DSR), bending beam rhometer (BBR), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), asphalt pavement analyzer (APA), dynamic modulus (DM) and flow number (FN) tests were used to analyze rheological properties and chemical bonding changes of the nano-modified asphalt binder and the performance of the nano-modified asphalt mixture In addition, the performance of nano-modified asphalt after rolling thin-film oven (RTFO) short-term and pressure-aging vessel (PAV) long-term aging was assessed as well

TL;DR: Weber and van Olphen as discussed by the authors provide valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems, including surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction-the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution.
Abstract: Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction-the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment-coagulation, filtration, membrane processes, chemical oxidation, and others-are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in ea

TL;DR: A challenge for future studies is to create hierarchically structured composites in which each sublayer contributes a distinct function to yield a mechanically integrated, multifunctional material.
Abstract: The mixing of polymers and nanoparticles is opening pathways for engineering flexible composites that exhibit advantageous electrical, optical, or mechanical properties. Recent advances reveal routes to exploit both enthalpic and entropic interactions so as to direct the spatial distribution of nanoparticles and thereby control the macroscopic performance of the material. For example, by tailoring the particle coating and size, researchers have created self-healing materials for improved sustainability and self-corralling rods for photovoltaic applications. A challenge for future studies is to create hierarchically structured composites in which each sublayer contributes a distinct function to yield a mechanically integrated, multifunctional material.
