Chemical education is essential to everybody because it deals with ideas that play major roles in personal, social, and economic decisions. This book is based on three principles: that all aspects of chemical education should be associated with research; that the development of opportunities for chemical education should be both a continuous process and be linked to research; and that the professional development of all those associated with chemical education should make extensive and diverse use of that research. It is intended for: pre-service and practising chemistry teachers and lecturers; chemistry teacher educators; chemical education researchers; the designers and managers of formal chemical curricula; informal chemical educators; authors of textbooks and curriculum support materials; practising chemists and chemical technologists. It addresses: the relation between chemistry and chemical education; curricula for chemical education; teaching and learning about chemical compounds and chemical change; the development of teachers; the development of chemical education as a field of enquiry. This is mainly done in respect of the full range of formal education contexts (schools, universities, vocational colleges) but also in respect of informal education contexts (books, science centres and museums).

Reviews of Environmental Contamination and Toxicology provides detailed review articles concerned with aspects of chemical contaminants, including pesticides, in the total environment with toxicological considerations and consequences.

This volume builds on an international workshop held in 2019, inspired by James Lovelock's "The Revenge of Gaia - Why the Earth Is Fighting Back, and How We Can Still Save Humanity". It, therefore, understands the Gaia concept as an umbrella term for the living world that planet Earth is hosting for nearly 4 billion years. Humankind has intervened in this ecosystem since its emergence on the planet about 2.5 million years ago, often with painful consequences for itself. In its reactions, the Earth system follows only the laws of nature. Consequently, humanity needs to develop strategies for a sustainable Earth system. This volume presents a unique trans- and interdisciplinary variety of approaches to this challenge, offering philosophical considerations as well as practical medical research. It addresses a broad knowledgeable and general audience in environmental management, public administration, and higher education alike.

This is the first of the two volumes that grew out of a series of lectures in the K computer project in Japan. The second volume will focus on advanced techniques and examples of applications in materials science.

The migration of substances from packaging to food is a matter of concern for the food safety authorities, and packaging materials constitute a potential source of contaminants to which the consumer will be exposed to through their diet. A huge variety of substances can be present in packaging materials, which could consequently migrate into food and represent a risk to consumer health. Food Contamination by Packaging provides an overview of the main packaging contaminants including Bisphenol A, melamine, phthalates, alternative plasticisers, photoinitiators, perfluorochemicals, saturated and aromatic hydrocarbons (mineral oil saturated hydrocarbons and mineral oil aromatic hydrocarbons) from mineral oils, other bisphenol-related compounds, nanoparticles, primary aromatic amines and nonintentionally added substances. The analytical techniques used for their determination are reviewed. This book will be of interest to students and researchers in universities and research institutions associated with food packaging and, in general, to the food safety sector.

Computational Chemistry serves as a complement to experimental chemistry where the tools are limited. Using computational programs to solve advanced problems is widely used in the design and analysis of for example new molecules, surfaces, drugs and materials. This book will present novel innovations in the field, with real-life examples of where computational technologies serves as an indispensible tool.

A modern approach to enzyme kinetics and its applications

As catalysts for the majority of metabolic and biochemical reactions in the body, enzymes are important drug targets as well as useful synthetic catalysts. Enzyme kinetics is the study of the speed of an enzyme-catalyzed reaction and provides useful knowledge that aids in the design of enzyme-based processes. A. G. Marangoni’s Enzyme Kinetics: A Modern Approach provides a practical, how-to guide for students, technicians, and nonspecialists to evaluate enzyme kinetics, using common software packages to perform easy enzymatic analyses.

The treatment of enzyme kinetics in this book is radically different from the way the topic is traditionally covered. Marangoni stresses an understanding of how researchers arrive at models, what the models’ limitations are, and how they can be used in practical ways to analyze enzyme kinetic data. With the advent of computers, linear transformations of models have become unnecessary–Enzyme Kinetics does away with all linear transformations of enzyme kinetic models, advancing the use of nonlinear regression techniques. Marangoni develops new ways to carry out analyses of enzyme kinetic data, particularly in the study of pH effects on catalytic activity and multisubstrate enzymes. Other topics addressed include:

• Tools and techniques of kinetic analysis
• Reversible and irreversible enzyme inhibition
• Multisite and cooperative enzymes
• Immobilized and interfacial enzymes
• Characterization of enzyme stability

Enzyme Kinetics is a handy, innovative resource for practicing researchers in the chemical, pharmaceutical, and food science industries.

This book explores recent advances in the microbial production of xylitol and its applications in food and medical sector. Xylitol is an important biomolecule from lignocellulose biorefinery which is produced from the xylose by chemical reactions or microbial fermentation methods. Currently, the demand of xylitol at commercial scale is being met through chemical methods. However, recent breakthroughs made in plant cell wall destruction, genetic engineering to develop the designer microorganisms, fermentation methods and media formulations and downstream processing have led the ways for sustainable production of xylitol at commercial scale in lignocellulose biorefineries. Microbial production of xylitol is preferred over the chemical processes as it is environmentally friendly, higher process efficiency with the desired product yield, and product recovery with minimum impurities. This book is a unique compilation of 11 book chapters written by experts in their respective fields. These chapters present critical insights and discuss the current progress and future progress in this area into fermentative xylitol production.
