Integrated Photonics for Data Communications Applications reviews the key concepts, design principles, performance metrics and manufacturing processes from advanced photonic devices to integrated photonic circuits. The book presents an overview of the trends and commercial needs of data communication in data centers and high-performance computing, with contributions from end users presenting key performance indicators. In addition, the fundamental building blocks are reviewed, along with the devices (lasers, modulators, photodetectors and passive devices) that are the individual elements that make up the photonic circuits. These chapters include an overview of device structure and design principles and their impact on performance. Following sections focus on putting these devices together to design and fabricate application-specific photonic integrated circuits to meet performance requirements, along with key areas and challenges critical to the commercial manufacturing of photonic integrated circuits and the supply chains being developed to support innovation and market integration are discussed. This series is led by Dr. Lionel Kimerling Executive at AIM Photonics Academy and Thomas Lord Professor of Materials Science and Engineering at MIT and Dr. Sajan Saini Education Director at AIM Photonics Academy at MIT. Each edited volume features thought-leaders from academia and industry in the four application area fronts (data communications, high-speed wireless, smart sensing, and imaging) and addresses the latest advances.

Current Developments in Biotechnology and Bioengineering: Membrane Technology for Sustainable Water and Energy Management covers a variety of advanced technologies for membrane processes, including water/wastewater treatment and reuse, membrane materials, operation and maintenance, fouling control, life cycle assessment, removal of micro/emerging pollutants, and operational cost of membrane processes. Supported by prominent editors and global contributors, this reference contains chapters on membrane treatment strategies for the current pollution of complex organic matters, nutrients, toxic substances, microplastics, membrane fouling control in different water resources, and reusing water resources through promising separation technologies, including reverse osmosis, forward osmosis, and membrane distillation.

Synthesis of Azetidines from Imines by Cycloaddition Reactions presents several methodologies for the synthesis of azetidines from imines by cycloaddition reactions.  The azetidines, known as important contribution of science to humanity, are important organic compounds that have occupied a basic position in the pharmaceutical chemistry for over a hundred years because of their biological activities. They are the fundamental skeleton of several antibiotics, probiotics and alkaloids. The synthesis of azetidines is a constant challenge for medicinal chemists, hence this book comprehensively describes azetidine ring synthesis. With this book, readers will be able to quickly assess possible synthetic approaches and evaluate whether preparation of a four-membered nitrogen containing ring is reasonable.

Heterocyclic frameworks represent the main structural subunits of many biologically active compounds and natural products. The ability of heterocycles to act both as reactive pharmacophores and biomimetics has greatly contributed to their unique value as traditional key elements of various drugs. The contemporary developments in process chemistry and discovery emphasize novel sustainable synthetic pathways as fast and ecologically acceptable alternatives to the traditional protocols. The development of sustainable synthetic process to substitute the efficient but somewhat old classical methodologies started many years back and such methodologies are still in high demand.  The increasing demand for fast formation of biologically active molecules has stimulated synthetic researchers to discover and develop smart approaches that inevitably address the very fundamental principles of effectiveness and efficiency. Besides the critical issues of stereo-, chemo-, and regioselectivity, nowadays, these processes also have to account economical and environment concerns of green chemistry. The intellectual difficulty to discover well-designed, concise, and conceptually new synthetic pathways has become a gradually increasing driving force in industry and academia. Since the last few years, chemists are very concerned about the environmental implications of their work. They are trying to develop novel reaction conditions, synthetic strategies, and use of chemicals that minimize risks to environment and humans. The development of harmless, atom efficient, and acid-mediated organic procedures is the most important challenge in green chemistry. While acid catalysis remains the most broadly utilized kind of catalysis, the generally employed acid catalysts continue to pose severe safety and health issues. The mild Lewis acidity of I2 has increased its applicability for many organic reactions.
