Book Description
In the last few decades great strides have been made in chemistry at the nanoscale, where the atomic granularity of matter and the exact positions of individual atoms are key determinants of structure and dynamics. Less attention, however, has been paid to the mesoscale-it is at this scale, in the range extending from large molecules (10 nm) through viruses to eukaryotic cells (10 microns), where interesting ensemble effects and the functionality that is critical to macroscopic phenomenon begins to manifest itself and cannot be described by laws on the scale of atoms and molecules alone. To further explore how knowledge about mesoscale phenomena can impact chemical research and development activities and vice versa, the Chemical Sciences Roundtable of the National Research Council convened a workshop on mesoscale chemistry in November 2014. With a focus on the research on chemical phenomena at the mesoscale, participants examined the opportunities that utilizing those behaviors can have for developing new catalysts, adding new functionality to materials, and increasing our understanding of biological and interfacial systems. The workshop also highlighted some of the challenges for analysis and description of mesoscale structures. This report summarizes the presentations and discussion of the workshop.

Dislocations, Mesoscale Simulations and Plastic Flow
Author: Ladislas Kubin
Publisher: OUP Oxford
ISBN: 0191664545
Category : Science
Languages : en
Pages : 320
Book Description
In the past twenty years, new experimental approaches, improved models and progress in simulation techniques brought new insights into long-standing issues concerning dislocation-based plasticity in crystalline materials. During this period, three-dimensional dislocation dynamics simulations appeared and reached maturity. Their objectives are to unravel the relation between individual and collective dislocation processes at the mesoscale, to establish connections with atom-scale studies of dislocation core properties and to bridge, in combination with modelling, the gap between defect properties and phenomenological continuum models for plastic flow. Dislocation dynamics simulations are becoming accessible to a wide range of users. This book presents to students and researchers in materials science and mechanical engineering a comprehensive coverage of the physical body of knowledge on which they are based. It includes classical studies, which are too often ignored, recent experimental and theoretical advances, as well as a discussion of selected applications on various topics.

ISBN: 0444634509
Category : Science
Languages : en
Pages : 493
Book Description
Chemical Imaging Analysis covers the advancements made over the last 50 years in chemical imaging analysis, including different analytical techniques and the ways they were developed and refined to link the composition and structure of manmade and natural materials at the nano/micro scale to the functional behavior at the macroscopic scale. In a development process that started in the early 1960s, a variety of specialized analytical techniques was developed – or adapted from existing techniques – and these techniques have matured into versatile and powerful tools for visualizing structural and compositional heterogeneity. This text explores that journey, providing a general overview of imaging techniques in diverse fields, including mass spectrometry, optical spectrometry including X-rays, electron microscopy, and beam techniques. - Provides comprehensive coverage of analytical techniques used in chemical imaging analysis - Explores a variety of specialized techniques - Provides a general overview of imaging techniques in diverse fields

Fluid Properties at Nano/Meso Scale
Author: Peter Dyson
Publisher: John Wiley & Sons
ISBN: 0470697377
Category : Technology & Engineering
Languages : en
Pages : 238
Book Description
Today’s scientific and engineering community has a good grasp on how to model fluid flows at macro and molecular scales, with well-developed theory and supporting technologies. Between these two extremes lies the nano/meso scale (i.e. in the range of 50nm-500nm) where fluid flow models continue to be problematic. Continuum models used at macro scales assume a negligible influence from molecular interactions, while molecular models do not predict flow well at nano/meso dimensions. The solution, and the subject of this book, is to use elements from both to capture correctly the proper physics (from the molecular scale) and provide a description in terms of useful fluid properties (as characterized on the continuum scale). Fluid Properties at Nano/Meso Scale is based on the authors’ past five years’ research that has yielded new innovations in fluid simulation strategies at the nano/meso scale. The authors approach this subject in a straightforward and easy to understand format, providing a first step into the subject for researchers at all levels. They present new tools that allow the numerical computation of fluid properties from first principles, enabling the reader to begin to model successfully fluids at nano/meso scale. It is hoped that these first steps will engender the further development and advancement of simulation techniques at this scale, and keep engineering simulation at the cutting edge of technology. Presents internationally leading developments in the field of fluid properties at nano/meso scale Provides the reader with the first steps to fluid modelling at nano/meso-scales as well as state-of-the-art applications Includes innovative and new simulation techniques along with a detailed examination of existing numerical methods
