This book details the latest research and development in the use of magnetic resonance imaging and spectroscopy as tools to give quantitative insights concerning late stage pharmaceutical formulation, tablet manufacturing and drug dissolution behaviour. The book combines different facets of magnetic resonance and highlights the use of spatial resolution (MRI) and how this adds to the knowledge base to further our understanding of the microscopic physicochemical processes occurring during drug release from solid dosage forms. New topics, that have not been thoroughly reviewed elsewhere, are covered including the applications of solution state magnetic resonance in process scale up, reaction monitoring/understanding and process analytical technologies (PAT); dissolution testing; and counterfeit analysis. Solid state NMR and its role in understanding phase separation in dispersions, polymorphism and crystallography are included and magnetic resonance imaging and its use in assessing tablet dissolution performance, mass transport and mixing in hot melt extrusion (HME) are covered.Focusing on late stage development rather than molecular drug discovery provides a unique approach and the book will appeal to a diversity of disciplines using spectroscopy for study. Aimed at researchers in drug development, manufacture and formulation in both industry (pharmaceutical companies) and academia (pharmacy program), it includes examples, where appropriate, of studies on commercially available pharmaceutical products.

Numerous practical applications of pyrolysis-GC/MS, for industrial and R&D usage, will be of benefit to Chemists and Engineers, as well as for students of Chemistry and Polymer Sciences.

Micro and nano devices are an integral part of modern technology. To address the requirements of the state-of-the-art technology, topics are selected from both chip-based and flexible electronics. A wide range of carbon materials including graphene, carbon nanotube, glass-like carbon, porous carbon, carbon black, graphite, carbon nanofiber, laser-patterned carbon and heteroatom containing carbon are covered. This goal is to elucidate fundamental carbon material science along with compatible micro- and nanofabrication techniques. Real-life example of sensors, energy storage and generation devices, MEMS, NEMS and implantable bioelectronics enable visualization of the outcome of described processes. Students will also benefit from the attractive aspects of carbon science explained in simple terms. Hybridization, allotrope classification and microstructural models are presented with a whole new outlook. Discussions on less-studied, hypothetical and undiscovered carbon forms render the contents futuristic and highly appealing.

Ionic liquids (ILs) play a crucial role in modern chemistry and chemical engineering. They remain more desirable than conventional volatile solvents and catalysts in many physical and chemical processes, often exhibiting green and designer properties for various applications. Examining the unique contribution of ILs towards current environmental challenges, this book addresses the importance of their role in the detection of micropollutants and decontamination processes in air and water compartments. It also presents a detailed review of how ILs impact the environment once released, a topic seldom covered in other books, and highlights novel chemoinformatic tools used to predict their fate, showing how advanced oxidation processes help in remediation. This is an ideal book for researchers in both academia and industry, and postgraduate students in environmental chemistry, chemical engineering and analytical chemistry looking at the potential applications of ionic liquids in addressing several environmental problems.

In todays'world with its widespread usage of personal-care products, pharmaceuticals, surfactants, flame retardants, plasticizers, various industrial additives, metals and metalloids, pesticides, and pesticide metabolites, environmental contaminants are an increasing source of pollution with a severe effect on the ecological system. Industries that produce these contaminants must find answers to remediate this.Nanomaterials in Environmental Analysis contributes to solving this problem by providing researchers in industry and academia with promising applications of nanoparticles in detection techniques and in removal of chemical species from the environment. Each chapter covers an aspect of using nanoparticles in detecting, measuring and remediating toxic chemical species in the environment. Explores the application of nanoparticles for the identification and quantification of pollutants from various environments Serves as a quick reference and source of knowledge on nanoparticles-based techniques for environmental applications Takes foundational knowledge for application to research in the area Provides future trends
