This book bridges disparate fields in an exploration of the phenomena and applications surrounding molecular mobility in glassy materials experiencing inelastic deformation. The subjects of plastic deformation and polymer motion/interdiffusion currently belong to the two different fields of continuum mechanics and polymer physics, respectively. However, molecular motion associated with plastic deformation is a key ingredient to gain fundamental understanding, both at the macroscopic and microscopic level. This short monograph provides necessary background in the aforementioned fields before addressing the topic of molecular mobility accompanied by macroscopic inelastic deformation in an accessible and easy-to-understand manner. A new phenomenon of solid-state deformation-induced bonding in polymers is discussed in detail, along with some broad implications in several manufacturing sectors. Open questions pertaining to mechanisms, mechanics, and modeling of deformation-induced bonding in polymers are presented. The book’s clear language and careful explanations will speak to readers of diverse backgrounds.

Material Mobilities explores the material dimension of various forms of mobilities and its implications for society, politics and everyday experiences as well as investigates how materials themselves are on the move. Together the different contributions and perspectives on material mobilities illustrate how materialities are critical components within mobilities but also shape how mobilities are produced and consumed within contemporary mobile societies. This insight may potentially influence the ways disciplines of mobilities understand and approach mobilities in the future. This book exemplifies how the new Mobilities turn may profit from foregrounding materials, the material, and materiality as a common pivot for social analysis. During the last decade of research affiliated to the ‘new mobilities turn’ the societal repercussions of intensive mobilities has been in focus. The ‘turn’ has documented the social, environmental, economic, and cultural effects of the contemporary patterns of movement of people, vehicles, goods, data and information. In parallel with this work new ideas and concepts about the human/non-human and the ‘material dimension’ of the social world has surfaced within a wide array of fields such as philosophy, anthropology, and cultural studies. Material Mobilities offers a materially sensitive and focused attention to the new Mobilities turn. The ‘turn to the material’ opens up a new set of research questions related to how artefacts and technologies facilitating and affording mobilities are being designed, constructed, and instituted. The new material interest furthermore points at new ways of comprehending the political and the power-dimensions of mobilities and infrastructural landscapes. The turn to the material furthermore problematizes the Modern binary distinctions between humans and non-humans, subjects and objects, culture and nature.

Over the last decade, the use of ion mobility separation in combination with mass spectrometry analysis has developed significantly. This technique adds a unique extra dimension enabling the in-depth analysis of a wide range of complex samples in the areas of the chemical and biological sciences. Providing a comprehensive guide to the technique, each chapter is written by an internationally recognised expert and with numerous different commercial platforms to choose from, this book will help the end users understand the practicalities of using different instruments for different ion mobility purposes. The first section provides a detailed account of the fundamentals behind the technique and the current range of available instrumentation. The second section focusses on the wide range of applications that have benefitted from ion mobility – mass spectrometry and includes topics taken from current research in the pharmaceutical, metabolomics, glycomics, and structural molecular biology fields. The book is primarily aimed at researchers, appealing to practising chemists and biochemists, as well as those in the pharmaceutical and medical fields.

Cell surface membranes have long been characterized as two-dimensional fluids whose mobile components are randomized by diffusion in the plane of the membrane bilayer. Recent research has indicated that cell surface membranes are highly organized and ordered and that important functional units of membranes appear as arrays of interacting molecules rather than as single, freely diffusing molecules. Mobility and Proximity in Biological Membranes provides an overview of the results obtained from biophysical methods for probing the organization of cell surface membranes. These results are presented in the context of detailed treatments of the theory and the technical demands of each of the methods. The book describes a versatile and easily applied mode for investigating molecular proximities in plasma membranes in a flow cytometer. Its analysis of lipid fluidity and viscosity of membranes and the rotational mobility of proteins offers intimate insight into the physical chemistry of biological membranes. The electrophysiology of lymphocytes is presented with focus on its importance in different diseases. New techniques are described, and new data, new possibilities, and future trends are presented by world experts. This book's chapters can serve both as guides to the existing literature and as starting points for new experiments and approaches associated with problems in membrane function.
