Reaching for the Sun
by John KingFrom their ability to use energy from sunlight to make their own food, to combating attacks from diseases and predators, plants have evolved an amazing range of life-sustaining strategies. Written with the non-specialist in mind, John King's lively natural history explains how plants function, from how they gain energy and nutrition to how they grow, develop and ultimately die. New to this edition is a section devoted to plants and the environment, exploring how problems created by human activities, such as global warming, pollution of land, water and air, and increasing ocean acidity, are impacting on the lives of plants. King's narrative provides a simple, highly readable introduction, with boxes in each chapter offering additional or more advanced material for readers seeking more detail. He concludes that despite the challenges posed by growing environmental perils, plants will continue to dominate our planet.

Reaction Engineering Principles
by Himadri Roy GhatakChemical reaction engineering is at the core of chemical engineering education. Unfortunately, the subject can be intimidating to students, because it requires a heavy dose of mathematics. These mathematics, unless suitably explained in the context of the physical phenomenon, can confuse rather than enlighten students. Bearing this in mind, Reaction Engineering Principles is written primarily from a student’s perspective. It is the culmination of the author’s more than twenty years of experience teaching chemical reaction engineering. The textbook begins by covering the basic building blocks of the subject—stoichiometry, kinetics, and thermodynamics—ensuring students gain a good grasp of the essential concepts before venturing into the world of reactors. The design and performance evaluation of reactors are conveniently grouped into chapters based on an increasing degree of difficulty. Accordingly, isothermal reactors—batch and ideal flow types—are addressed first, followed by non-isothermal reactor operation, non-ideal flow in reactors, and some special reactor types. For better comprehension, detailed derivations are provided for all important mathematical equations. Narrative of the physical context in which the formulae work adds to the clarity of thought. The use of mathematical formulae is elaborated upon in the form of problem solving steps followed by worked examples. Effects of parameters, changing trends, and comparisons between different situations are presented graphically. Self-practice exercises are included at the end of each chapter.

Examples refer to themes according to the headings given in the table of contents and are arranged in a hierarchical order.
Reaction Kinetics: An Introduction
by Ernő KeszeiThis book covers all basic topics of reaction kinetics, thus students do not need to refer to other resources to prepare for an undergraduate exam. It leads the reader into the topic starting from molecular level concepts and working towards the more macroscopic descriptions of kinetics, introducing the subject according to the state-of-the-art 21st century chemistry. A thorough treatment of formal kinetics of both elementary and complex reactions is based on actual practice, omitting many obsolete treatments of the subject. Mathematical operations are explained in enough detail so that even students that are less trained in calculus can easily follow and understand. Data treatment and statistical inference include modern - mostly numerical - methods widely used in applications. Experimental methods are described using basic technical details, however as techniques quickly change sophisticated devices are not the focus of this book. The emphasis lies on providing the basic concepts which are important for students to understand. This book is suitable as essential reading for courses in bachelor and master chemistry programs and is also valuable as a reference or textbook for students of physics, biochemistry and environmental science.
Reaction Kinetics: Mathematica for Deterministic and Stochastic Kinetics
by János Tóth Attila László Nagy Dávid PappFifty years ago, a new approach to reaction kinetics began to emerge: one based on mathematical models of reaction kinetics, or formal reaction kinetics. Since then, there has been a rapid and accelerated development in both deterministic and stochastic kinetics, primarily because mathematicians studying differential equations and algebraic geometry have taken an interest in the nonlinear differential equations of kinetics, which are relatively simple, yet capable of depicting complex behavior such as oscillation, chaos, and pattern formation. The development of stochastic models was triggered by the fact that novel methods made it possible to measure molecules individually. Now it is high time to make the results of the last half-century available to a larger audience: students of chemistry, chemical engineering and biochemistry, not to mention applied mathematics. Based on recent papers, this book presents the most important concepts and results, together with a wealth of solved exercises. The book is accompanied by the authors’ Mathematica package, ReactionKinetics, which helps both students and scholars in their everyday work, and which can be downloaded from http://extras.springer.com/ and also from the authors’ websites. Further, the large set of unsolved problems provided may serve as a springboard for individual research.
Reaction Kinetics Based on Time-Energy Uncertainty Principle
by Satoru YamamotoThis book proposes a completely unique reaction kinetics theory based on the uncertainty principle of quantum mechanics; the physical viewpoint and mathematical details for the theory construction are explained, and abundant applications of the theory mainly in materials science are described. The theory argues that physical systems on reaction are in a quantum-mechanically uncertain state, and that such systems will transition to new states after a finite duration time. Based on this theory, if the magnitude of the energy uncertainty, i.e., energy fluctuation of the system on reaction can be determined, we can calculate the reaction rates not only for the thermal activation processes but also for the non-thermal activation process such as mechanical, optical, electromagnetic, or other actions. Therefore, researchers or engineers who are involved in fields such as the discovery of new chemical substances, development of materials, innovation of manufacturing processes, and also everyone purely interested in kinetic methodology find this book very stimulating and motivating.
Reaction Mechanisms in Carbon Dioxide Conversion
by Michele Aresta Angela Dibenedetto Eugenio QuarantaThis book provides an analysis of the reaction mechanisms relevant to a number of processes in which CO2 is converted into valuable products. Several different processes are considered that convert CO2 either in specialty chemicals or in bulk products or fuels. For each reaction, the mechanism is discussed and the assessed steps besides the dark sites of the reaction pathway are highlighted. From the insertion of CO2 into E-X bonds to the reduction of CO2 to CO or other C1 molecules or else to C2 or Cn molecules, the reactions are analysed in order to highlight the known and obscure reaction steps. Besides well known reaction mechanisms and energy profiles, several lesser known situations are discussed. Advancing knowledge of the latter would help to develop efficient routes for the conversion of CO2 into valuable products useful either in the chemical or in the energy industry. The content of this book is quite different from other books reporting the use of CO2. On account of its clear presentation, "Reaction Mechanisms in Carbon Dioxide Conversion" targets in particular researchers, teachers and PhD students.

Reactions: An Illustrated Exploration of Elements, Molecules, and Change in the Universe
by Theodore GrayThe long-awaited third installment in Theodore Gray's iconic "Elements" trilogy. The first two titles, Elements and Molecules, have sold more than 1.5 million copies worldwide. With Reactions bestselling author Theodore Gray continues the journey through our molecular and chemical world that began with the tour de force The Elements and continued with Molecules. In The Elements, Gray gave us a never-before-seen, mesmerizing photographic view of the 118 elements in the periodic table. In Molecules, with the same phenomenal photographic acumen, plus beautifully rendered computer generated graphics, he showed us how the elements combine to form the content that makes up our universe, from table salt to oxygen to the panoply of colors and smells that surround us. At last, we've reached Reactions, in which Gray once again puts his photography and storytelling to work demonstrating how molecules interact in ways that are essential to our very existence. The book begins with a brief recap of elements and molecules and then goes on to explain important concepts the characterize a chemical reaction, including Energy, Entropy, and Time. It is then organized by type of reaction including chapters such as "Fantastic Reactions and Where to Find Them," "On the Origin of Light and Color," "The Boring Chapter," in which we learn about reactions such as paint drying, grass growing, and water boiling, and "The Need for Speed," including topics such as weather, ignition, and fire.

Reactivating Elements: Chemistry, Ecology, Practice (Elements)
by Dimitris Papadopoulos, Maria Puig De La Bellacasa, & Natasha MyersThe contributors to Reactivating Elements examine chemicals as they mix with soil, air, water, and fire to shape Earth's troubled ecologies today. They invoke the elements with all their ambivalences as chemical categories, material substances, social forms, forces and energies, cosmological entities, and epistemic objects. Engaging with the nonlinear historical significance of elemental thought across fields—chemistry, the biosciences, engineering, physics, science and technology studies, the environmental humanities, ecocriticism, and cultural studies—the contributors examine the relationship between chemistry and ecology, probe the logics that render wind as energy, excavate affective histories of ubiquitous substances such as plastics and radioactive elements, and chart the damage wrought by petrochemical industrialization. Throughout, the volume illuminates how elements become entangled with power and control, coloniality, racism, and extractive productivism while exploring alternative paths to environmental destruction. In so doing, it rethinks the relationship between the elements and the elemental, human and more-than-human worlds, today’s damaged ecosystems and other ecologies to come.Contributors.

Reactive Intermediates in Organic Chemistry
by Maya Shankar SinghMost reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product. In the course of these multi-step reaction sequences, short-lived intermediates can be generated that quickly convert into other intermediates, reactants, products or side products. As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Using the information obtained, researchers can better understand the underlying reaction mechanism of a certain organic transformation and thus develop novel strategies for efficient organic synthesis.The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates. Additionally, representative examples and a problem section with different levels of difficulty are included for self-testing the newly acquired knowledge.By providing a deeper understanding of the underlying concepts, this is a musthave reference for PhD and Master Students in organic chemistry, as well as a valuable source of information for chemists in academia and industry working in the field. It is also ideal as primary or supplementary reading for courses on organic chemistry, physical organic chemistry or analytical chemistry.
