Plasma-processed biomimetic structures are an extremely focused and small subset of biomimetics. Although other methods can also be adopted, experimental synthesis of biomimetic structures mainly focuses on plasma processing. This book deals with the theoretical description of photonic structures available in nature, and the physics and applications of biomimetic structures prepared in the laboratory. It discusses anti-reflection properties of moth eye- or cicada wing-type nanostructured materials on semiconductor surfaces, with emphasis on plasma fabrication procedures. It also explains, with the help of related theories, the superhydrophobic or hydrophilic wetting properties demonstrated by most of these natural structures. It discusses biomedical applications, especially in implants, as one of the key applications of such materials. The book focuses mainly on plasma processing of biomimetic nanostructures and is, therefore, different from similar books that are more general in nature. It presents essential schematics, sufficient details, and advanced instrumentation techniques that would help readers understand why these structures are considered so important in materials science and physics.

The book outlines first the importance of Extra Cellular Matrix (ECM), which is a natural surface for most of cells. In the following chapters the influence of biological, chemical, mechanical, and physical properties of surfaces in micro and nano-scale on stem cell behavior are discussed including the mechanotransduction. Biomimetic and bioinspired approaches are highlighted for developing microenvironment of several tissues, and surface engineering applications are discussed in tissue engineering, regenerative medicine and different type of biomaterials in various chapters of the book. This book brings together innovative methodologies and strategies adopted in the research and development of Advanced Surfaces in Stem Cell Research. Well-known worldwide researchers deliberate subjects including: Extracellular matrix proteins for stem cell fate The superficial mechanical and physical properties of matrix microenvironment as stem cell fate regulator Effects of mechanotransduction on stem cell behavior Modulation of stem cells behavior through bioactive surfaces Influence of controlled micro and nanoengineered surfaces on stem cell fate Nanostructured polymeric surfaces for stem cells Laser surface modification techniques and stem cells applications Plasma polymer deposition: a versatile tool for stem cell research Application of bioreactor concept and modeling techniques in bone regeneration and augmentation treatments Substrates and surfaces for control of pluripotent stem cell fate and function Application of biopolymer-based, surface modified devices in transplant medicine and tissue engineering Silk as a natural biopolymer for tissue engineering

This book comprises a first survey of the Collaborative Research Center SFB-TRR 141 ‘Biological Design and Integrative Structures – Analysis, Simulation and Implementation in Architecture’, funded by the Deutsche Forschungsgemeinschaft since October 2014. The SFB-TRR 141 provides a collaborative framework for architects and engineers from the University of Stuttgart, biologists and physicists from the University of Freiburg and geoscientists and evolutionary biologists from the University of Tübingen. The programm is conceptualized as a dialogue between the disciplines and is based on the belief that that biomimetic research has the potential to lead everyone involved to new findings far beyond his individual reach. During the last few decades, computational methods have been introduced into all fields of science and technology. In architecture, they enable the geometric differentiation of building components and allow the fabrication of porous or fibre-based materials with locally adjusted physical and chemical properties. Recent developments in simulation technologies focus on multi-scale models and the interplay of mechanical phenomena at various hierarchical levels. In the natural sciences, a multitude of quantitative methods covering diverse hierarchical levels have been introduced. These advances in computational methods have opened a new era in biomimetics: local differentiation at various scales, the main feature of natural constructions, can for the first time not only be analysed, but to a certain extent also be transferred to building construction. Computational methodologies enable the direct exchange of information between fields of science that, until now, have been widely separated. As a result they lead to a new approach to biomimetic research, which, hopefully, contributes to a more sustainable development in architecture and building construction.

Recent progress in enhancing and refining the performance and properties of wood composites by chemical and thermal modification and the application of smart multi-functional coatings have made them a particular area of interest for researchers. Wood Composites comprehensively reviews the whole field of wood composites, with particular focus on their materials, applications and engineering and scientific advances, including solutions inspired biomimetrically by the structure of wood and wood composites. Part One covers the materials used for wood composites and examines wood microstructure, and wood processing and adhesives for wood composites. Part Two explores the many applications of wood composites, for example plywood, fibreboard, chipboard, glulam, cross-laminated timber, I-beams and wood-polymer composites. The final part investigates advances in wood composites and looks at the preservation and modification of wood composites, environmental impacts and legislative obligations, nano-coatings and plasma treatment, biomimetic composite materials, the integration of wood composites with other materials and carbonized and mineralized wood composites. Comprehensively reviews the entire field of wood composites in a single volume Examines recent progress in enhancing and refining the performance and properties of wood composites by chemical and thermal modification and the application of smart multi-functional coatings Explores the range of wood composites, including both new and traditional products

Integral Urbanism is an ambitious and forward-looking theory of urbanism that offers a new model of urban life. Nan Ellin's model stands as an antidote to the pervasive problems engendered by modern and postmodern urban planning and architecture: sprawl, anomie, a pervasive culture - and architecture - of fear in cities, and a disregard for environmental issues. Instead of the reactive and escapist tendencies characterizing so much contemporary urban development, Ellin champions an 'integral' approach that reverses the fragmentation of our landscapes and lives through proactive design solutions.

Materials with superhydrophobic or related properties are one of the most studied subjects from a theoretical point of view and also for the large range of possible applications, for example, anticorrosion, antibacteria, optical devices, and sensors. The study of natural species with special wettability has shown us the importance of surface structures and the surface energy of the resulting surface properties. Various strategies can be used to reproduce superhydrophobic phenomena in the laboratory. General reviews on superhydrophobic properties already exist but, to our knowledge, do not focus on metallic and inorganic materials. Here, we focus especially on the strategies implemented for reaching superhydrophobic or related properties using metallic and inorganic materials. Indeed, these materials present unique properties, for example, thermal and mechanical resistance, chemical and ageing resistance, and optical (transparency, antireflection, photoluminescence) and electrical properties (conducting, semiconducting, insulating). This book will be useful for graduate students of materials chemistry and physics and for researchers in surface science, nanostructures, and bioinspired or biomimetic materials.

This book introduces various 3D printing systems, biomaterials, and cells for organ printing. In view of the latest applications of several 3D printing systems, their advantages and disadvantages are also discussed. A basic understanding of the entire spectrum of organ printing provides pragmatic insight into the mechanisms, methods, and applications of this discipline. Organ printing is being applied in the tissue engineering field with the purpose of developing tissue/organ constructs for the regeneration of both hard (bone, cartilage, osteochondral) and soft tissues (heart). There are other potential application areas including tissue/organ models, disease/cancer models, and models for physiology and pathology, where in vitro 3D multicellular structures developed by organ printing are valuable.
