Crystallization is a natural occurring process but also a process abundantly used in the industry. Crystallization can occur from a solution, from the melt or via deposition of material from the gas phase (desublimation). Crystals distinguish themself from liquids, gases and amorphous substances by the long-range order of its building blocks that entail the crystals to be formed of well-defined faces, and give rise to a large number of properties of the solid. Crystallization is used at some stage in nearly all process industries as a method of production, purification or recovery of solid materials. Crystallization is practiced on all scales: from the isolation of the first milligrams of a newly synthesized substance in the research laboratory to isolating products on the mulit-million tonne scale in industry. The book describes the breadth of crystallization operations, from isolation from a reaction broth to purification and finally to tailoring product properties. In the first section of the book, the basic mechanisms - nucleation, growth, attrition and agglomeration are introduced. It ensures an understanding of supersaturation, the driving force of crystallization. Furthermore, the solubility of the substance and its dependences on process conditions and the various techniques of crystallization and their possibilities and limitations are discussed. Last but not least, the first part includes an intensive treatment of polymorphism . The second part builds on the basics, exploring how crystallization processes can be developed, either batch-wise or continuous, from solution or from the melt. A discussion of the purification during crystallization serves as a link between the two sections, where practical aspects and an insight using theoretical concepts are combined. Mixing and its influence on the crystallization as well as the mutual interference of down-stream processes with the crystallization are also treated. Finally, techniques to characterize the crop are discussed. The third part of the book is dedicated to accounts of actual developments and of carried-out crystallizations. Typical pitfalls and strategies to avoid these as well as the design of robust processes are presented.

This manageably sized dictionary covers theory, experiment, industrial practice and applications for nanotechnology, colloid, and interface science, as well as much of what is now termed materials science. The comprehensive information is presented in several sections and formats: dictionary of terms, classification tables on colloid and nanomaterial types, and sub-term glossaries for specific phenomena, properties and methods. It offers both newly-coined as well as older terms whose meanings have changed, providing acronyms, synonyms, famous names, selected abbreviations, and cross-references. It also contains a historical overview, units and symbols, and a separate literature section for further reading and following-up on specific topics. An authoritative reference, vital for unhindered communication and knowledge transfer in this fast-growing and broadly interdisciplinary field.

This second edition has 20% more scope, with four completely new chapters and eight existing ones completely revised to include more modeling, more industrial examples, new coating types, and new medical applications. Combining theory and practice from design to application, the monograph continues to provide a state-of-the-art treatise on plasma spray technology, beginning with the principles and techniques. Successive chapters treat the three important stages of energy transfer from the plasma to the surface, with modeling, depositing, testing and applying ceramic and metallic coatings covered in the shape of industrial problem solution examples. Concluding with quality control and a new section on biomedical issues and opportunities, the book offers pertinent knowledge for materials scientists, engineers, biologists and medical researchers alike.

This first introductory-level textbook on the design of small molecules is written with the first-time user in mind. Aimed at students and scientists alike, it uses computer-based methods to design and analyze such small molecules as drugs, enzyme inhibitors, probes and markers for biomolecules. Both authors have extensive practical experience of modeling and design and share their knowledge of what can and cannot be done with computer-assisted design. Divided into four sections, the book begins with a look at molecular objects and design objectives, including molecular geometry, properties, recognition and dynamics. Two further sections deal with virtual synthesis and screening, while the final section covers navigation in chemical space. The result is a textbook that takes the modeler one step further, to the de novo design of functional molecules. With its study questions at the end of each learning unit, this is equally suitable for teaching and self-learning.

Despite all the efforts being put into expanding renewable energy sources, large-scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear plants whose protective function means they are classified as safety-related, have to meet particular construction requirements more stringent than those involved in conventional construction. This book gives a comprehensive overview from approval aspects given by nuclear and construction law, with special attention to the interface between plant and construction engineering, to a building structure classification. All life cycle phases are considered, with the primary focus on execution. Accidental actions on structures, the safety concept and design and fastening systems are exposed to a particular treatment. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about "sick buildings", thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards energy efficiency, decarbonization and sustainability - all these have accelerated the development of a discipline that, for a long time, was hardly more than an academic exercise: building physics. The discipline embraces domains such as heat and mass transfer, building acoustics, lighting, indoor environmental quality, energy efficiency, and, in some countries, fire safety. Through the application of physical knowledge and its combination with information coming from other disciplines, building physics helps to under-stand the physical phenomena governing building parts, building envelope, whole building and built environment performance - called urban physics. Today, building physics has be-come a key player on the road to highly performing new buildings and renovations. The first book deals with heat, air and moisture transport in building parts or assemblies and whole buildings with emphasis on the building engineering applications. The second book on applied building physics focuses on the question of what a well-balanced building performance consists of. Here, the environmental loads on buildings are explained - i.e. all those parameters that describe the external and internal environmental conditions, with an emphasis on practical implementation. Then follows a comprehensive presentation of those performance requirements that are important at the whole-building level, mainly considering thermal, acoustic, visual and olfactory comfort, indoor air quality, energy consumption, durability, economy and sustainability. This is followed by an in-depth discussion of the requirements regarding thermal, air and moisture behaviour as well as the measured variables at the level of the building construction and components. The analyses and calculations described in this book result in sustainable buildings made of functional and durable building constructions, with comfortable and healthy indoor climate. Compared to the previous editions, both books have been expanded to include the physical determination of the thermal conductivity of materials, together with an in-depth discussion of all the effects of thicker insulation layers. Additional information has been added on wind pressure and the evaluation of condensation inside the building components, while a new chapter on material properties has been included. Both volumes, including the figures, have been revised and restructured where necessary.
