Available in PDF, EPUB and Kindle. Book excerpt: The field of gas phase inorganic ion chemistry is relatively new; the early studies date back approximately twenty years, but there has been intense interest and development in the field in the last ten years. As with much of modern chemistry, the growth in gas phase inorganic ion chemistry can be traced to the development of instrumentation and new experimental methods. Studies in this area require sophisticated instruments and sample introduc tion/ ionization methods, and often these processes are complicated by the need for state-selecting (or collisionally stabilizing) the reactive species in order to assign the chemistry unequivocally. At the present level of experimental development, a wide range of experiments on diverse ionic systems are possible and many detailed aspects of the chemistry can be studied. Gas Phase Inorganic Chemistry focuses on the reactions of metal ions and metal clusters, and on the study of these species using the available modern spectroscopic methods. Three of the twelve chapters cover the chemistry of ionic monometal transition metal ions and the chemistry of these species with small diatomics and model organics. Two of the chapters focus on the studies of the chemical and physical properties of (primarily) transition metal clusters, and these chapters review experimental methods and capabilities. Two chapters also deal with the chemistry of transition metal carbonyl clusters, and these chapters address issues important to cluster growth and activation as well as the characterization of such species.

Download or read book Modern Mass Spectrometry written by Christoph A. Schalley and published by Springer. This book was released on 2003-07-03 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometers are used by almost all chemists and many researchers from neighboring disciplines such as physics, medicine, or biology as a powerful a- lytical tool. Its advantages are high sensitivity, speed, and almost no sample c- sumption. During the last two decades, mass spectrometry experienced a boom of new developments pushing its limits further and further at an increasing speed - just similar to the progress in NMR spectroscopy in the 1970s. However, a mass spectrometer does not only serve as a machine for solving complicated analytical problems, it evolved meanwhile to a complete laboratory for the investigation of molecules, clusters, and other species under the envir- ment-free conditions of the highly diluted gas phase. These special conditions existing only in high vacuum change the properties of the particles under study significantly with respect to their energetics and reaction pathways. For ex- ple, temperature is a macroscopic property of a large ensemble of particles in thermal equilibrium and is thus not defined for a single ion. This fact has severe implications for the measurement of kinetic and thermodynamic data of g- phase species. On the other hand, the examination of gas-phase properties has the advantage that systems reduced to minimum complexity can be studied more easily without the complicated influences of solvents or counterions. In parti- lar, the combination of isotopic labeling and mass spectrometry allows for a detailed analysis of reaction mechanisms or conformational analysis through H/D exchange experiments not only on biomolecules.

Download or read book The Chemistry of Organogold Compounds 2 Volume Set written by Zvi Rappoport and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 1158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book in the PATAI Series was published in 1964 and the Series will celebrate its 50th Anniversary in 2014. This "Golden Jubilee" is accompanied by the publication of the first volume on the chemistry of organogold. In the history of the PATAI Series there was, so far, no volume dedicated to gold alone. In 1999 we published a volume on The Chemistry of Gold and Silver Compounds. Since then a lot of new chemistry using gold has been developed and it is timely to focus a volume on methods and applications of organogold compounds in organic synthesis, reflecting the enormous progress which has been made in the use of gold compounds as reagents and catalysts. A second area of great importance covered in the book is the use of gold surfaces in the synthesis of peptides, proteins and other natural products. A whole range of applications in the area of biochemistry has resulted from these developments. A third area of interest is the synthesis and engineering of nanostructures, where organogold chemistry has opened the door for a wide range of methods and applications in the field of nanoscience and materials science. As with all new volumes, the chapters are first published online in Patai's Chemistry of Functional Groups. Once a volume is completed online, it is then published in print format. The printed book offers the traditional quality of the Patai Book Series, complete with an extensive index.

This book was released on 2008-10-22 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the fourth time, the Leibniz Supercomputing Centre (LRZ) and the Com- tence Network for Technical, Scienti c High Performance Computing in Bavaria (KONWIHR) publishes the results from scienti c projects conducted on the c- puter systems HLRB I and II (High Performance Computer in Bavaria). This book reports the research carried out on the HLRB systems within the last three years and compiles the proceedings of the Third Joint HLRB and KONWIHR Result and Reviewing Workshop (3rd and 4th December 2007) in Garching. In 2000, HLRB I was the rst system in Europe that was capable of performing more than one Tera op/s or one billion oating point operations per second. In 2006 it was replaced by HLRB II. After a substantial upgrade it now achieves a peak performance of more than 62 Tera op/s. To install and operate this powerful system, LRZ had to move to its new facilities in Garching. However, the situation regarding the need for more computation cycles has not changed much since 2000. The demand for higher performance is still present, a trend that is likely to continue for the foreseeable future. Other resources like memory and disk space are currently in suf cient abundance on this new system.

Download or read book Structure Reactivity and Thermochemistry of Ions written by Pierre Ausloos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of a 1986 Advanced Study Institute entitled "Structure/Reactivity and Thermochemistry of Ions", held at Les Arcs, France, June 30 to July 11, 1986. The format of a NATO Institute is ideally suited to in-depth communications between scien tists of diverse backgrounds. Particularly in the field of ion physics and chemistry, where on-going research involves physicists, physical chemists, and organic chemists - who use a variety of experimental and theoretical techniques - it is found that in the relaxed but stimula ting atmosphere of a NATO ASI, each professional group provides unique insights, leading to a better definition and solution of problems relating to the properties of gas phase ions. This book presents chapters based on the lectures presented at the Les Arcs ASI. The participants took the initiative to organize a number of specialized workshops - informal discussion groups which considered questions or problem areas of particular interest. The accounts of these sessions, which are also included in this book, make stimulating reading, and include considerable useful information. This Advanced Study Institute is the fourth in a series of NATO-spon sored institutes devoted to the chemistry and physics of ions in the gas phase. The first, in 1974, in Biarritz, France, focussed on "Interactions between Ions and Molecules".

Download or read book Physics and Chemistry of Small Clusters written by P. Jena and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in experimental techniques now enable researchers to produce in a laboratory clusters of atoms of desired composition from any of the elements of the periodic table. This has created a new area of research into novel materials since clusters cannot be regarded either as a "large" molecule or as a fragment of the bulk. Both experimental and theoretical studies are revealing unusual properties that are not ob served in solid state environments. The structures of micro-clusters are found to be significantly distorted from the most symmetric arrangement, some even exhibiting pentagonal symmetry commonly found in icosahedric structures. The unusual stability of certain clusters, now described as "magic number species", shows striking similarities with the nuclear shell structure. The relative stabilities of clusters depend not only on the composition of the clusters but also on their charged states. The studies on spontaneous fragmentation of mUltiply charged clusters, commonly referred to as Coulomb explosion, illustrate the role of electronic bonding mechanisms on stability of clusters. The effect of foreign atoms on geometry and stability of clusters and the interaction of gas atoms with clusters are showing promise for an indepth understanding of chemisorption and catalysis. The magnetic and optical properties are dependent not only on cluster size but also on its geometry. These findings have the potential for aiding industry in the area of micro-electronics and catalysis.

Book excerpt: Spectroscopy and Modeling of Biomolecular Building Blocks presents an overview of recent advances in the intertwining of the following research fields: photon and electron spectroscopy, quantum chemistry, modelling and mass-spectrometry. The coupling of these disciplines offers a new point of view to the understanding of isolated elementary building blocks of biomolecules and their assemblies. It allows the unambiguous separation between intrinsic properties of biomolecular systems and those induced by the presence of their environment. The first chapters provide background in modelling (I), frequency-resolved spectroscopy using microwave, infrared and UV photons, time-resolved spectroscopy in the femtosecond domain and energy-resolved electron spectroscopy (II) and production of gas-phase neutral and ionic biomolecular species, mass-spectrometry, ion mobility and BIRD techniques (III). Chapter IV is devoted to case studies of gas-phase experimental investigations coupled to quantum or classical calculations. The topics are structural studies of nucleobases and oligonucleotides, peptides and proteins, sugars; neuromolecules; non-covalent complexes; chiral systems, interactions of low-energy electrons with biomolecules in the radiation chemistry context and very large gas-phase biomolecular systems. The fifth chapter concerns the link between gas-phase and liquid-phase. Different treatments of solvation are illustrated through examples pointing out the influence of progressive addition of water molecules upon properties of nucleobases, peptides, sugars and neuromolecules. - Offer a new perspective to the understanding of isolated elementary building blocks of bio molecules - Includes case studies of experimental investigations coupled to quantum or classical calculations

Download or read book Methane Conversion Routes written by Vladimir Galvita and published by Royal Society of Chemistry. This book was released on 2023-09-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently the majority of carbon-based feedstocks come from fossil fuels of which there is a finite supply. Methane is an abundantly available carbon-based feedstock, with large amounts now available through fracking and renewable sources available from biogas plants. However, methane is not very chemically reactive. One of the remaining “grand challenges” in chemistry is the development of clean, efficient, affordable processes that allow methane to be converted to other high value molecules. Highlighting the recent advances in methane activation and direct conversion processes this book discusses the progress and current state of the art for a wide variety of alternative methane activation and subsequent conversion processes, including homogeneous and heterogeneous catalytic, electrocatalytic and pyrolytic systems. It is a useful resource for anyone working in green chemistry, catalysis and chemical engineering.
