Book Synopsis Self-Assembly Processes at Interfaces by : Vincent Ball

Download or read book Self-Assembly Processes at Interfaces written by Vincent Ball. This book was released on 2018-02-13. Available in PDF, EPUB and Kindle. Book excerpt: Self-Assembly Processes at Interfaces: Multiscale Phenomena provides the conceptual and unifying view of adsorption, self-assembly, and grafting processes at solid–liquid and liquid–gas interfaces, also describing experimental methods where applicable. An invaluable resource for (post)-graduate students looking to bridge the gap between acquiring the field's existing knowledge and the creation of new insights, the book recalls fundamental concepts, giving rigorous, but first-principle-based, calculations and exercises, and showing how these concepts have been used in recent research articles. Readers will find guidelines on how best to start research in the field of surface chemistry with biological macromolecules and molecules able to undergo self-assembly process at interfaces in the presence of a liquid, along with discussions on the very fundamental aspects and applications using concepts of biomimetic chemistry. By highlighting the interdisciplinary aspects of the field of self-assembly at interfaces, the book is an ideal resource for chemical engineers, chemists, physicists, and biologists. In addition, important equations are demonstrated on the basis of fundamental concepts, and overly complex mathematical developments are avoided. - Presents an interdisciplinary work that is ideal for chemical engineers, chemists, physicists, and biologists - Provides a unifying view of the field, from fundamentals, to methods and applications - Includes concepts applicable at both solid–liquid and liquid–gas interfaces

Book Synopsis Self-assembly at Ionic Liquid-based Interfaces by : Denzil Frost

Download or read book Self-assembly at Ionic Liquid-based Interfaces written by Denzil Frost. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: Liquid-liquid interfaces serve as ideal 2-D templates on which solid particles can self-assemble into various structures. These self-assembly processes are important in fabrication of micron-sized devices and emulsion formulation. At oil/water interfaces, these structures can range from close-packed aggregates to ordered lattices. By incorporating an ionic liquid (IL) at the interface, new self-assembly phenomena emerge. ILs are ionic compounds that are liquid at room temperature (essentially molten salts at ambient conditions) that have remarkable properties such as negligible volatility and high chemical stability and can be optimized for nearly any application. The nature of IL-fluid interfaces has not yet been studied in depth. Consequently, the corresponding self-assembly phenomena have not yet been explored. We demonstrate how the unique molecular nature of ILs allows for new self-assembly phenomena to take place at their interfaces. These phenomena include droplet bridging (the self-assembly of both particles and emulsion droplets), spontaneous particle transport through the liquid-liquid interface, and various gelation behaviors. In droplet bridging, self-assembled monolayers of particles effectively "glue" emulsion droplets to one another, allowing the droplets to self-assembly into large networks. With particle transport, it is experimentally demonstrated the ILs overcome the strong adhesive nature of the liquid-liquid interface and extract solid particles from the bulk phase without the aid of external forces. These phenomena are quantified and corresponding mechanisms are proposed. The experimental investigations are supported by molecular dynamics (MD) simulations, which allow for a molecular view of the self-assembly process. In particular, we show that particle self-assembly depends primarily on the surface chemistry of the particles and the non-IL fluid at the interface. Free energy calculations show that the attractive forces between nanoparticles and the liquid-liquid interface are unusually long-ranged, due to capillary waves. Furthermore, IL cations can exhibit molecular ordering at the IL-oil interface, resulting in a slight residual charge at this interface. We also explore the transient IL-IL interface, revealing molecular interactions responsible for the unusually slow mixing dynamics between two ILs. This dissertation, therefore, contributes to both experimental and theoretical understanding of particle self-assembly at IL based interfaces.

Download or read book Understanding Self-assembly in Solution and at Interfaces Using All-atom Molecular Dynamics Simulations and Enhanced Sampling Methods written by Arushi Prakash. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: Proteins and biopolymers self-assemble to form nanostructures in solution or at interfaces. Notable examples include, the formation of plaque during Alzheimer’s disease, and the formation of protein-templates for biomineralization. Even though these assembly processes are well-studied, they remain poorly understood. The focus of this dissertation is to investigate early-stage assembly processes, including adsorption of particles on surfaces, and oligomer formation using classical molecular dynamics and enhanced sampling methods (like metadynamics and umbrella sampling). As these systems are explored, improved protocols for enhanced sampling of protein-adsorption simulations are developed to tackle the roles of ions in simulations, and to incorporate experimental data into the sampling using Bayesian inference. Further, a new sampling method is developed to make these enhanced sampling simulations more efficient.

Book Synopsis Protein Self-Assembly by : Jennifer J. McManus

Download or read book Protein Self-Assembly written by Jennifer J. McManus. This book was released on 2020-08-08. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores experimental and computational approaches to measuring the most widely studied protein assemblies, including condensed liquid phases, aggregates, and crystals. The chapters in this book are organized into three parts: Part One looks at the techniques used to measure protein-protein interactions and equilibrium protein phases in dilute and concentrated protein solutions; Part Two describes methods to measure kinetics of aggregation and to characterize the assembled state; and Part Three details several different computational approaches that are currently used to help researchers understand protein self-assembly. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, Protein Self-Assembly: Methods and Protocols is a valuable resource for researchers who are interested in learning more about this developing field.
