Book Description
Non-conventional synthetic methods may provide new and green methods for the preparation of bioactive heterocycles. These methods, such as microwave and ultrasound assisted synthesis, biocatalysis, photochemistry and electrosynthesis use less energy and may produce less waste to get the desired products when compared to traditional methods. This book explores the use of these methods when synthesizing various biologically relevant heterocyclic scaffolds. THE SERIES: GREEN BIOACTIVE HETEROCYCLES Heterocycles are a widely utilized group of molecules as they often contain bioactivity that is useful in drug development, agriculture, and other applications. However, their synthesis remains challenging with diffi cult to control functional groups. With a greater focus on sustainable synthesis practices, there is a need to develop greener synthetic methods for the synthesis of structurally diverse bioactive heterocyclic scaffolds. This series aims to do so, by collecting developments into common themes.

Book Description
The considerable proliferation of new glasses during the second half of the 20th century (germanate, vanadate, bismuthate, tellurite, chalchogenide glasses, etc.) brought about the use the plural form of the 4 generic glass denomination, in order to be able to index each emerging glass family by its proper name, as well as to classify them methodically. Together with its great compositional versatility, the peculiar characteristics of glass (non-crystalline structure with short-range order, continuous network with no intergranular boundaries, isotropy, easy to be formed into a plastic state inside a wide temperature range) allow for a freedom of design and adaptability that few materials are able to offer. All these circumstances have contributed to the fact that, in the last seventy years, glass has acquired the multiple and varied appearance of its new families, without losing neither its original image nor its soda-lime-silica traditional composition, destined for the huge industrial manufacture of its conventional products.

Book Description
The international symposium "Fundamentals of Biocatalysis in Non-Conventional Media" was organized under auspices of the working party Applied Biocatalysis of the European Federation of Biotechnology. Among the topics discussed at the symposium were physical-chemical aspects such as pH, water-activity, viscosity, dielectric constants, polarity etc. in relation to biocatalysis in non-conventional media. New measuring techniques were introduced. For people working in the field of biocatalysis in non-conventional media this book will give an excellent overview of the gain in understanding over the last five years of the fundamental aspects of biocatalysis in non-conventional media.

Book Description
Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.

Book Description
The book presents new research in the area of biobased “green composites”. Biobased materials involve renewable agricultural and forestry feedstocks, including wood, agricultural waste, grasses and natural plant fibers. These lignocellulosic materials are composed mainly of carbohydrates such as sugar and lignin, cellulose, vegetable oils and proteins. Much research is concerned with renewable materials such as bamboo, vegetable fibers, soil composites and recycled materials such as rice husk ash and sugar cane ash. The general aim here is to use renewable and non-polluting materials in ways that offer a high degree of sustainability and preserve the remaining natural resources for future generations. Keywords: Biobased Materials, Renewable Materials, Non-polluting Materials, Sustainability, Wood, Agricultural Waste, Grasses, Natural Plant Fibers, Lignocellulosic Materials, Carbohydrates, Sugars, Lignin, Cellulose, Vegetable Oils, Proteins, Bamboo, Vegetable Fibers, Soil Composites, Recycled Materials, Rice Husk Ash, Sugar Cane Ash, Fiber-reinforced Concrete, Post-disaster Reconstruction, Guadua Fibers, Prefabricated Bamboo Guadua Panels, Multi-Level Bamboo Structures, Alkaline Activated Cements, Polymer Residues Reinforced with Glass Fiber, Composites Reinforced with Vegetal Fibers, Sisal Fibers, Bamboo Arch Structure, Adobe Reinforced with Wheat Fibers, Fiber Reinforced Microconcrete, Cements with High Coal Waste Contents, Natural Composites, Geopolymer Concretes.

Book Description
For more than a century, heterocycles have played a crucial role in the biological and industrial development of society, becoming one of the most researched areas within organic chemistry. The first chapter of Microwave-Induced Synthesis of Aromatic Heterocycles is based on microwave theory, the latest developments in instrumentation technology, and the various microwave technologies used for synthesis. The remainder of the chapters are divided into two sections. Section A deals with the five-membered heterocycles (pyrazoles, isoxazoles, triazoles, oxadiazoles, thiazoles, imidazoles, oxazoles, oxazolines etc.) and in Section B, various six-membered heterocycles (triazines, benzoxazoles, benzimidazoles, benzothiazoles) are presented. Both sections contain a detailed, recent literature review of microwave assisted synthesis and its applicability to various aromatic heterocyclics.
