Book Description
Foreword Porous mineral materials can be damaged by both physical and chemical attack. The presence of an aggressive solution in the pores may induce dissolution of the porous substrate and precipitation of damaging solids, cause chemical changes, or induce swelling processes, all of which lead to damaging mechanical stresses and substrate loss. These damage mechanisms can be denoted altogether as corrosion. Corrosive processes are dependent on the moisture, the temperature, and the concentration and nature of the carried species in the solution as well as on the flux rate at variable concentration and other boundary conditions. From 2002 until 2009 the DFG has financially supported our research in the field of materials science in civil engineering, which is focused on the time-dependent description and prediction of the cited damage mechanisms of porous mineral materials by using numerical simulation under real field conditions. Hereby, the modeling of microstructures and transport processes has been extensively studied. The present book holds the reports published by the involved institutes. Each report contains a summary of the main results achieved in their research. High mathematical complexity and computing cost linked to thorough knowledge of physical chemistry has been required for the successful achievement of the research goals. Indeed, the implemented numerical models and simulation programs, some of which are in ongoing development, provide for an increasingly useful tool to predict the described corrosive processes in engineering and underground constructions as well as in historic buildings.

Book Description
Moisture dynamics in brick, stone and concrete has a controlling influence on the durability and performance of the built environment. Water Transport in Brick, Stone and Concrete provides a unified description of transport processes involving saturated and unsaturated flow in porous inorganic materials and structures. It sets out fundamental physics and materials science, mathematical description and experimental measurement as a basis for engineering design and construction practice. Now in its third edition, the book combines a systematic presentation of the scientific and technical principles with new analyses of topics such as sorption isotherms, temperature dependence of sorptivity, time-dependent properties of cement-based materials, layered materials, air-trapping and driving rain. It serves as an authoritative reference for research workers, practising engineers and students of civil, building, architectural and materials engineering. Much of the fundamental work is relevant to engineers in soil science and geotechnics, as well as oilfield, chemical and process engineering.

Book Description
The present work reflects a multi-disciplinary effort to address the topic of confined hydrosystems developed with a cross-fertilization panel of physics, chemists, biologists, soil and earth scientists. Confined hydrosystems include all situations in natural settings wherein the extent of the liquid phase is limited so that the solid-liquid and/or liquid-air interfaces may be critical to the properties of the whole system. Primarily, this so-called “residual” solution is occluded in pores/channels in such a way that decreases its tendency to evaporation, and makes it long-lasting in arid (Earth deserts) and hyper-arid (Mars soils) areas. The associated physics is available from domains like capillarity, adsorption and wetting, and surface forces. However, many processes are still to understand due to the close relationship between local structure and matter properties, the subtle interplay between the host and the guest, the complex intermingling among static reactivity and migration pathway. Expert contributors from Israel, Russia, Europe and US discuss the behaviour of water and aqueous solutes at different scale, from the nanometric range of carbon nanotubes and nanofluidics to the regional scale of aquifers reactive flow in sedimentary basins. This scientific scope allowed the group of participants with very different background to tackle the confinement topic at different scales. The book is organized according to four sections that include: i) flow, from nano- to mega-scale; ii) ions, hydration and transport; iii) in-pores/channels cavitation; iv) crystallization under confinement. Most of contributions relates to experimental works at different resolution, interpreted through classic thermodynamics and intermolecular forces. Simulation techniques are used to explore the atomic scale of interfaces and the migration in the thinnest angstrom-wide channels.

Book Description
Most materials used in contemporary life and industry are heterogeneous (composites) and multicomponent, possessing a rich and complex internal structure. This internal structure, or microstructure, plays a key role in understanding and controlling the continuum behavior, or macroscopic, of a wide variety of materials. The modeling process is a critical tool for scientists and engineers studying the analysis and experimentation for the micromechanics and behavior of these materials. "Heterogeneous Media" is a critical, in-depth edited survey of the major topics surrounding the modeling and analysis of problems in micromechanics of multicomponent systems, including conceptual and practical aspects. The goal of this extensive and comprehensive survey is to provide both specialists and nonspecialists with an authoritative and interdisciplinary perspective of current ideas and methods used for modeling heterogeneous materials behavior and their applications. Topics and Features: * all chapters use interdisciplinary modeling perspective for investigating heterogeneous media*Five chapters provide self-contained discussions, with background provided*Focuses only upon most important techniques and models, fully exploring micro-macro interconnections*extensive introductory survey chapter on micromechanics of heterogeneous media*microstructure characterization via statistical correlation functions*micro-scale deformation of pore space*wave fields and effective dynamical properties*modeling of the complex production technologies for composite materials The book is ideal for a general scientific and engineering audience needing an in-depth view and guide to current ideas, methods and

Book Description
Bone tissue engineering aims to develop artificial bone substitutes that partially or totally restore the natural regeneration capability of bone tissue lost under circumstances of injury, significant defects, or diseases such as osteoporosis. In this context, biomaterials are the keystone of the methodology. Biomaterials for bone tissue engineering have evolved from biocompatible materials that mimic the physical and chemical environment of bone tissue to a new generation of materials that actively interacts with the physiological environment, accelerating bone tissue growth. Mathematical modelling and simulation are important tools in the overall methodology. This book presents an overview of the current investigations and recent contributions in the field of bone tissue engineering. It includes several successful examples of multidisciplinary collaboration in this transversal area of research. The book is intended for students, researchers, and professionals of a number of disciplines, such as engineering, mathematics, physics, chemistry, biomedicine, biology, and veterinary. The book is composed of an editorial section and 16 original research papers authored by leading researchers of this discipline from different laboratories across the world
