High-Performance Materials from Bio-based Feedstocks

In recent years, the utilization of terpyridines both in macromolecular structure assembly and device chemistry has exploded, enabling, for example, supramolecular polymer architectures with switchable chemical and physical properties as well as novel functional materials for optoelectronic applications such as light-emitting diodes and solar cells. Further applications include the usage of terpyridines and their metal complexes as catalysts for asymmetric organic reactions and, in a biological context, as anti-tumor agents or biolabels. This book covers terpyridine-based materials topics ranging from syntheses, chemistry, and multinuclear metal complexes, right up to functionalized polymers, 3D-architectures, and surfaces. Aimed at materials scientists, (in)organic chemists, polymer chemists, complex chemists, physical chemists, biochemists, and libraries.

Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1.

It is well known that solid carbons can be found in various guises with different forms of bulk phases (graphites, diamonds and carbynes) as well as more molecular forms (fullerenes,nanotubes and graphenes) resulting from recent discoveries. The cause of this rich polymorphism is analyzed in the first part of this book (chapters 1-5) with the propensity of carbon atoms for forming different types of homopolar chemical bonds associated with variable coordination numbers. Precursor organic molecules and parent compounds are also described to establish specific links with this rich polymorphism. Then in a second part (chapters 6-10) a comparative review of the main classes of bulk physical properties is presented. This approach emphasizes in particular the electronic behavior of (pi) polyaromatic systems organized in plane and curved atomic sheets. Finally in a third part (chapters 11-15) the surface and interface characteristics are introduced together with the texture and morphology of these multiscale carbon materials. An overview of the main field of applications is related showing the large use and interest for these solids.
