Chemical formulation can be traced back to Stone Age times, when hunter-gatherers attached flint arrowheads to shafts using a resin made from birch bark and beeswax. Today, formulated preparations are part of everyday life. Formulations based on surfactants are by far the most prolific, from shampoos and shower gels to emulsion paint and polishes. This book discusses the chemical technology of surfactants and related chemicals, using over forty examples of everyday products. Some basic theory on surface chemistry, molecular interactions and surfactant function is included to aid understanding. Chemical Formulation: An Overview of Surfactant-based Preparations Used in Everyday Life then goes on to look at wider aspects such as surfactant manufacture, raw materials, environment, sustainability, analysis and testing. Throughout, common chemical names are used for formulation chemicals, further aiding the readability of the book. Bridging the gap between theory and application, this book will be invaluable to anyone wishing to broaden their knowledge of applied chemistry, including students on A level, BTEC and technician courses. It will also be of benefit to those new to the formulation industry.

Bees are critically important for ecosystem function and biodiversity maintenance through their pollinating activity. Unfortunately, bee populations are faced with many threats, and evidence of a massive global pollination crisis is steadily growing. As a result, there is a need to understand and, ideally, predict how bees respond to pollution disturbance, to the changes over landscape gradients, and how their responses can vary in different habitats, which are influenced to different degrees by human activities. Modeling approaches are useful to simulate the behavior of whole population dynamics as well as to focus on important phenomena detrimental to bee-life history traits. They also allow simulation of how a disease or a pesticide can impact the survival and growth of a bee population. In Silico Bees provides a collection of computational methods to those primarily interested in the study of the ecology, ethology, and ecotoxicology of bees. The book presents different cases studies to enable readers to understand the significance and also the limitations of models in theoretical and applied bee research. The text covers modeling of honey bee society organization, infectious diseases in colonies, pesticide toxicity, chemical contamination of the hive, and more. Written by an international team of scientists, this book is of primary interest to those whose research or professional activity is directly concerned with the study of bees. It is also intended to provide graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches that can be used in terrestrial ecology and ecotoxicology.
Juvenile hormones (JHs) are a group of structurally related sesquiterpenes secreted by the insect corpora allata. They affect most insect life-cycle stages and physiological functions, including embryogenesis, larval and adult development, metamorphosis, reproduction, metabolism, diapause, polyethism, and migration. Juvenoids such as methoprene, hydroprene, kinoprene, pyriproxyfen, and fenoxycarb are man-made chemicals that mimic the structure and/or activity of JHs, selectively targeting and disrupting the endocrine system of insects. They are particularly suited as larvicides for the control of pest and disease vectoring insects such as mosquitoes. Juvenile Hormones and Juvenoids: Modeling Biological Effects and Environmental Fate discusses the various modeling approaches that can be used to study the mechanism of action of JHs in insects and to estimate the adverse effects and the environmental fate of the juvenoids that mimic their activity. This book is the third of the QSAR in Environmental and Health Sciences series, but the first dedicated to the use of QSAR and other in silico techniques to provide these insights into JHs and their analogs. With contributions by an international team of scientists, the book begins with a historical survey of JHs and juvenoids. It then discusses biosynthesis of sesquiterpenoids followed by chapters covering JH activity such as morph-specific JH titers in crickets, and JH analog activity including soldier-specific organ development in termites and the role of methoprene in gene transcription. The book examines modeling approaches applied to resistance to JH analogs, to population dynamics of nontarget species in the presence of juvenoids, and to SAR and QSAR of JH mimics. The book concludes with a discussion on the use of multicriteria analysis for selecting insecticides for vector control.

Sulfur compounds contaminate many industrially important feedstocks and, on release to the atmosphere as sulfur oxides, can cause widespread damage to the ecosystem. The main objectives of The Sulfur Problem: Cleaning Up Industrial Feedstocks are to demonstrate the importance of eliminating sulfur contaminants from the environment and the measures necessary to effect this. Using a systematic and pedagogical approach, the reader is first presented with the problem. Current technology for solving it is then outlined together with appropriate theory on the synthesis, structure and sorption behaviour of the materials used. Relevant characterisation techniques are described with reference to typical sorbents, to demonstrate how the sorption behaviour of the materials correlates with their properties. The book is unique in blending together aspects of environmental chemistry, materials/solid state chemistry, surface chemistry, catalysis and separation processes to address the problem of sulfur contaminants in a wide range of feedstocks.

Complex Systems are natural systems that science is unable to describe exhaustively. Examples of Complex Systems are both unicellular and multicellular living beings; human brains; human immune systems; ecosystems; human societies; the global economy; the climate and geology of our planet. This book is an account of a marvelous interdisciplinary journey the author made to understand properties of the Complex Systems. He has undertaken his trip, equipped with the fundamental principles of physical chemistry, in particular, the Second Law of Thermodynamics that describes the spontaneous evolution of our universe, and the tools of Non-linear dynamics. By dealing with many disciplines, in particular, chemistry, biology, physics, economy, and philosophy, the author demonstrates that Complex Systems are intertwined networks, working in out-of-equilibrium conditions, which exhibit emergent properties, such as self-organization phenomena and chaotic behaviors in time and space.
Simple, but beautifully versatile.
