This book was released on 2011 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Implementation and development of novel nanoscale biomedical devices and procedures depends critically upon the ability to manufacture affordable nanoscale polymer structures. This, in turn, depends upon understanding of the properties of the polymer materials at these scales, where material properties are often divergent from those observed at larger scales. In this thesis, a molecular dynamics (MD) based approach is developed to analyze these properties at an atomic resolution. Under the hypothesis that the emergence of new properties in nanoscale polymers is due to the increased importance of interface effects, the primary focus of this work is the differentiation of material behavior at various interfaces.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the dynamics of low molecular weight and polymeric molecules when they are constrained under conditions of geometrical confinement. It covers geometrical confinement in different dimensionalities: (i) in nanometer thin layers or self supporting films (1-dimensional confinement) (ii) in pores or tubes with nanometric diameters (2-dimensional confinement) (iii) as micelles embedded in matrices (3-dimensional) or as nanodroplets. The dynamics under such conditions have been a much discussed and central topic in the focus of intense worldwide research activities within the last two decades. The present book discusses how the resulting molecular mobility is influenced by the subtle counterbalance between surface effects (typically slowing down molecular dynamics through attractive guest/host interactions) and confinement effects (typically increasing the mobility). It also explains how these influences can be modified and tuned, e.g. through appropriate surface coatings, film thicknesses or pore diameters. "Dynamics in Confinement" sums up the present state-of-the-art and introduces to the analytical methods of choice for the study of dynamics in nanometer-scale confinement.

This book was released on 2016 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous polymeric materials are increasingly used in a variety of technologies ranging from organic electronics to gas separation membranes. As many of these applications trend towards the nanoscale, it is imperative to know how the properties of nanoscale polymer glasses compare to those of the bulk material. While many cases have shown that the dynamics of the interfaces affect the properties of a thin film, the length scales of these effects are still heavily debated. In this thesis, I use ellipsometry to perform cooling rate dependent Tg measurements in order to probe the average length scales of interfacial dynamics in ultra-thin polymer glasses. These studies show that segmental motion from the surfaces of a film can influence the dynamics of a material over length scales up to 40 nm, which is over ten times the length scale of segmental motion. Furthermore, they show that while factors such as polymer molecular weight, chain stiffness, and attractive substrate interactions can have an effect on the overall dynamics of the system, they do not change the fact that the dynamics from the air/polymer and polymer/substrate interfaces propagate through the film over long length scales.

Book excerpt: Model thin films relevant to various biomaterials applications were used to investigate the interfacial phenomena that occur on polymeric surfaces. Quartz Crystal Microbalance with Dissipation (QCM-D) was used to investigate conformational change of soft materials, adsorption and desorption kinetics of macromolecules and interaction between absorbates and model surfaces. Specifically, this thesis deals with enzymatic activity on this films of cellulose of lignin, and salt- induced changes for surface-grafted neutral thermoresponsive polymers. It was possible to study in situ and in real time the dynamics of enzymatic activity with the QCM-D. After an initial phase, which was controlled by enzyme binding on the substrate, an increase in the resonant frequency of the sensor was apparent. This increase of frequency was explained by the reduction in effective mass due to enzymatic degradation. The rate at which this degradation occurs was found to depend strongly on the enzyme concentration, temperature and the pH of the solution as well as the mixing conditions within the reaction cell. QCM-D was also employed to estimate the effect of salt on the volume phase transition of thermoresponsive polymer brushes. Changes in mass and viscoelasticity of grafted poly (N-isopropyl acrylamide) (PNIPAM) layers grafted from QCM-D sensors were measured as a function of temperature, upon contact with aqueous solutions of variable salt concentration. The phase transition temperature of PNIPAM brushes, TC, graft, quantified by using the QCM-D was reduced with increases in the concentration of salt. This phenomenon is explained by the tendency of salt ions to affect structure of water molecules (Hofmeister effect). The investigation on changes in the hydrophlicity of milled wood lignin films were studied by QCM-D and static contact angle mesurements. After laccase incubation, significant decrease in resonant frequency and increase in energy dissipation was observed. It was demonstrated t.

Download or read book Falling Liquid Films written by S. Kalliadasis and published by Springer Science & Business Media. This book was released on 2011-09-24 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Falling Liquid Films gives a detailed review of state-of-the-art theoretical, analytical and numerical methodologies, for the analysis of dissipative wave dynamics and pattern formation on the surface of a film falling down a planar inclined substrate. This prototype is an open-flow hydrodynamic instability, that represents an excellent paradigm for the study of complexity in active nonlinear media with energy supply, dissipation and dispersion. It will also be of use for a more general understanding of specific events characterizing the transition to spatio-temporal chaos and weak/dissipative turbulence. Particular emphasis is given to low-dimensional approximations for such flows through a hierarchy of modeling approaches, including equations of the boundary-layer type, averaged formulations based on weighted residuals approaches and long-wave expansions. Whenever possible the link between theory and experiment is illustrated, and, as a further bridge between the two, the development of order-of-magnitude estimates and scaling arguments is used to facilitate the understanding of basic, underlying physics. This monograph will appeal to advanced graduate students in applied mathematics, science or engineering undertaking research on interfacial fluid mechanics or studying fluid mechanics as part of their program. It will also be of use to researchers working on both applied, fundamental theoretical and experimental aspects of thin film flows, as well as engineers and technologists dealing with processes involving isothermal or heated films. This monograph is largely self-contained and no background on interfacial fluid mechanics is assumed.

Book excerpt: "the present book will be of great value for both newcomers to the field and mature active researchers by serving as a coherent and timely introduction to some of the modern approaches, ideas, results, emerging understanding, and many open questions in this fascinating field of polymer glasses, supercooled liquids, and thin films" –Kenneth S. Schweizer, Morris Professor of Materials Science & Engineering, University of Illinois at Urbana-Champaign (from the Foreword) This book provides a timely and comprehensive overview of molecular level insights into polymer glasses in confined geometries and under deformation. Polymer glasses have become ubiquitous to our daily life, from the polycarbonate eyeglass lenses on the end of our nose to large acrylic glass panes holding water in aquarium tanks, with advantages over glass in that they are lightweight and easy to manufacture, while remaining transparent and rigid. The contents include an introduction to the field, as well as state of the art investigations. Chapters delve into studies of commonalities across different types of glass formers (polymers, small molecules, colloids, and granular materials), which have enabled microscopic and molecular level frameworks to be developed. The authors show how glass formers are modeled across different systems, thereby leading to treatments for polymer glasses with first-principle based approaches and molecular level detail. Readers across disciplines will benefit from this topical overview summarizing the key areas of polymer glasses, alongside an introduction to the main principles and approaches.
