Molecular carbon chains have attracted much interest for more than 130 years, but the length of chains is limited to 44 atoms even by sophisticated chemical synthesis. Recently, the artificial synthesis of long linear carbon chains, “carbynes,” has revived, and their existence was firmly substantiated using the latest advanced analytical methods, such as high-resolution electron microscopy and Raman scattering spectroscopy. Until the 1980s, graphite and diamond were the well-known allotropic forms of elemental carbon, which were two-dimensional (2D) and 3D crystals, respectively. Carbyne is the ultimate 1D nanowire with atomic diameter and its synthesis has opened prospects for versatile properties of carbon materials. Carbyne is a 1D semiconductor with a direct transition energy gap and interesting properties such as extreme mechanical strength are expected from it. This book comprehensively reviews and describes the latest chemical and physical synthesis methods, theoretically predicted properties, and possible applications of carbyne.

Carbyne (e.g., linear chains of sp-bonded carbon) has been the subject of intense research focus due to its presence in astrophysical bodies, as well as its potential for use as a nanoelectronic device and superhard material. In this work, we discuss the formation of carbyne fiber bundles over a nanosecond time scale in laser pulse melting studies, using a previously determined density functional tight binding model for carbon coupled with a new correction for the dispersion energy. We determine our dispersion energy model by optimizing a modified Lennard-Jones potential to an experimentally determined equation of state for graphite, yielding excellent results for the bulk modulus and density under ambient conditions. We then simulate previous experiments by heating graphite to high temperature, followed by expanding the ensuing liquid phase to low density. Our results indicate that the initial, hot liquid phase mainly consists of sp2-bonded carbon atoms, which form a system of sp-bonded strands bound together via dispersion interactions upon achieving low density and temperature. Lastly, the high computational efficiency of our approach allows for direct comparison with experiments that span a wide range of thermodynamic conditions and can help determine parameters for synthesis of carbon-based materials with potentially exotic properties.

Polyynes: Synthesis, Properties, and Applications compiles information found scattered throughout the literature in inorganic, organic, and polymer chemistry into one cohesive volume. In addition to being a precursor of fullerenes, polyynes are one of the key precursors in the formation of soot and carbon dust, or elemental carbon in the gal

Ecosystems have been present in the fields of economics and management for decades, and in recent years they have experienced rapid development. However, there is still no consensus on the definition of an innovation ecosystem. Using concrete examples, The Innovation Ecosystem as a Source of Value Creation proposes a unique model in order to refine the understanding, functions, advantages and disadvantages of innovation ecosystems. This model is based on both the iterative network and integrated value chain. The network supports the collaboration between actors and favors asset transfers articulated around the innovation process. This book highlights the transfer processes at work in the innovation ecosystem, as well as the roles of the actors in this integrated value chain. It presents how value creation is articulated around knowledge to generate value shared by all of the actors in the innovation ecosystem.

The section devoted to iron in this volume reflects the tremendous progress in the area. Specifically cluster chemistry, ligand transformations and detailed structural results are more prominent in COMC II. The organic chemistry of ruthenium and osmium is an area which has burgeoned during the period since the publication of COMC. This is especially true for the cluster chemistry of these elements, which have provided most of the advances in this important field. Consequently, this volume will include an update (1981-1993) of the chemistry of mono- and bi-nuclear complexes of ruthenium and osmium, with a rather more extensive treatment of tri- and tetra-nuclear complexes. This is because many of the early results in ruthenium and osmium cluster chemistry described in COMC are now much better understood and can thus be placed in a more general context. In the case of complexes containing clusters with five or more metal atoms, the coverage is essentially complete, again because this chemistry has developed during the 1980s.

Modern Inorganic Synthetic Chemistry, Second Edition captures, in five distinct sections, the latest advancements in inorganic synthetic chemistry, providing materials chemists, chemical engineers, and materials scientists with a valuable reference source to help them advance their research efforts and achieve breakthroughs. Section one includes six chapters centering on synthetic chemistry under specific conditions, such as high-temperature, low-temperature and cryogenic, hydrothermal and solvothermal, high-pressure, photochemical and fusion conditions. Section two focuses on the synthesis and related chemistry problems of highly distinct categories of inorganic compounds, including superheavy elements, coordination compounds and coordination polymers, cluster compounds, organometallic compounds, inorganic polymers, and nonstoichiometric compounds. Section three elaborates on the synthetic chemistry of five important classes of inorganic functional materials, namely, ordered porous materials, carbon materials, advanced ceramic materials, host-guest materials, and hierarchically structured materials. Section four consists of four chapters where the synthesis of functional inorganic aggregates is discussed, giving special attention to the growth of single crystals, assembly of nanomaterials, and preparation of amorphous materials and membranes. The new edition’s biggest highlight is Section five where the frontier in inorganic synthetic chemistry is reviewed by focusing on biomimetic synthesis and rationally designed synthesis. Focuses on the chemistry of inorganic synthesis, assembly, and organization of wide-ranging inorganic systems Covers all major methodologies of inorganic synthesis Provides state-of-the-art synthetic methods Includes real examples in the organization of complex inorganic functional materials Contains more than 4000 references that are all highly reflective of the latest advancement in inorganic synthetic chemistry Presents a comprehensive coverage of the key issues involved in modern inorganic synthetic chemistry as written by experts in the field

Organometallic chemistry is an interdisciplinary science which continues to grow at a rapid pace. Although there is continued interest in synthetic and structural studies the last decade has seen a growing interest in the potential of organometallic chemistry to provide answers to problems in catalysis synthetic organic chemistry and also in the development of new materials. This Specialist Periodical Report aims to reflect these current interests reviewing progress in theoretical organometallic chemistry, main group chemistry, the lanthanides and all aspects of transition metal chemistry. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
