The origin of life is one of the biggest unsolved scientific questions. This book deals with the formation and first steps of the chemical evolution of nucleic acids, including the chemical roots behind the origin of their components from the simplest sources in a geochemical context. Chemical evolution encompasses the chemical processes and interactions conducive to self-assembly and supramolecular organization, leading to an increase of complexity and the emergence of life. The book starts with a personal account of the pioneering work of Stanley Miller and Jeffrey Bada on the Chemistry of Origins of Life and how the development of organic chemistry beginning in the 19th century led to the emergence of the field of prebiotic chemistry, situated at the frontier between organic, geo- and biochemistry. It then continues reviewing in tutorial manner current central topics regarding the organization of nucleic acids: the origin of nucleobases and nucleosides, their phosphorylation and polymerization and ultimately, their self-assembly and supramolecular organization at the inception of life.
This thesis offers a unique guide to the development and application of ultrasensitive optical microscopy based on light scattering. Divided into eight chapters, it covers an impressive range of scientific fields, from basic optical physics to molecular biology and synthetic organic chemistry. Especially the detailed information provided on how to design, build and implement an interferometric scattering microscope, as well as the descriptions of all instrumentation, hardware interfacing and image processing necessary to achieve the highest levels of performance, will be of interest to researchers now entering the field.
This book focuses on the microscopic understanding of the function of organic semiconductors. By tracing the link between their morphological structure and electronic properties across multiple scales, it represents an important advance in this direction. Organic semiconductors are materials at the interface between hard and soft matter: they combine structural variability, processibility and mechanical flexibility with the ability to efficiently transport charge and energy. This unique set of properties makes them a promising class of materials for electronic devices, including organic solar cells and light-emitting diodes. Understanding their function at the microscopic scale - the goal of this work - is a prerequisite for the rational design and optimization of the underlying materials. Based on new multiscale simulation protocols, the book studies the complex interplay between molecular architecture, supramolecular organization and electronic structure in order to reveal why some materials perform well - and why others do not. In particular, by examining the long-range effects that interrelate microscopic states and mesoscopic structure in these materials, the book provides qualitative and quantitative insights into e.g. the charge-generation process, which also serve as a basis for new optimization strategies.

Volume 11 of this series presents five timely reviews on current
research on alkaloids. Chapter 1 by Paul L. Schiff, Jr. is a
monumental survey of research that has been carried out over the
past decade on the "Thalictrum" alkaloids. Forty-six new alkaloids
are described from fifteen species of the genus "Thalictrum," as
well as 116 alkaloids of known structure from thirty-six species
and subspecies of the genus. The chapter includes discussions of
isolation and structure elucidation, analysis, biosynthesis, cell
culture, and pharmacology. Also featured are inclusive compilations
of botanical sources, alkaloids by alkaloid types, and calculated
molecular weights of the "Thalictrum" alkaloids. Chapter 2 by Giovanni Appendino provides a fascinating treatment
of Taxine, a collective name referring to a mixture of diterpenoid
alkaloids from the yew tree (genus: "Taxus"). Taxine is responsible
for the toxic properties of the yew tree that has been documented
in historical and fictional literature, from Julius Caesar to
Shakespeare, and from Agatha Christie to T.S. Eliot. The chapter
treats the history, isolation techniques, structure elucidation,
chemistry, and pharmacology of Taxine. Chapter 3 by Mary D. Menachery surveys the alkaloids of South
American Menispermaceae (moonseed family). Many different
structural types are included in this family. The alkaloid-bearing
plants are woody-vines, shrubs, or small trees. Several of these
species possess potent curare activity. The chemistry as well as
pharmacology of these alkaloids is summarized. Chapter 4 by Russell J. Molyneux, Robert J. Nash, and Naoki
Asano treats the chemistry and biological activity of the
calystegines and related "nor"tropane alkaloids. These
polyhydroxylated bicyclic alkaloids represent another class of
compounds that inhibit glycosidases, producing profound effects in
biological systems by disrupting the essential cellular function of
glycoprotein processing. Chapter 5, a related chapter by Robert J. Nash, Naoki Asano, and Alison A. Watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. Topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.

Considering the challenge of sustainability facing our society in the coming decades, catalysis is without any doubt a research area of major importance. In this regard, asymmetric organocatalysis, now considered a pillar of green chemistry, deserves particular attention. The first chapter of this volume examines the topic of asymmetric organocatalysis in light of radical chemistry. Recent important progress in this field has been attained by promoting the formation and harnessing the high reactivity of open-shell intermediates. Merging organocatalysis with radical chemistry has been the key to solving some longstanding bottlenecks, and has also significantly contributed to reinforcing the key role of organocatalysis in asymmetric catalysis. This chapter presents the most significant developments in this area, with a particular focus on asymmetric SOMO- and photoredox-organocatalyzed transformations. Chapter 2 focuses on quaternary ammonium salts (R4N+X-), especially chiral derivatives, and their behavior as unique catalysts in organocatalysis. Forming chiral ion-pairs capable of promoting asymmetric reactions, they also operate as unique "transporters" involved in phase transfer catalytic processes between liquid-liquid or liquid-solid systems. Furthermore, they offer unique opportunities when forming cooperative ion-paired entities R4N+X-, allowing a synergistic implication of the counter-ion X- either as Bronsted bases or Lewis bases. Specific design of such chiral catalysts in modern chemistry and better insight into their mode of activation facilitates efficient and unprecedented chemical transformations. This chapter provides an overview of the use of chiral quaternary ammonium salts in organocatalysis, emphasizing both general mechanistic aspects and the scope of this approach.
