This book was released on 2013-04-17 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief historical account of the background leading to the publication of the first four editions of the World Directory of Crystallographers was presented by G. Boom in his preface to the Fourth Edition, published late in 1971. That edition was produced by traditional typesetting methods from compilations of biographical data prepared by national Sub-Editors. The major effort required to produce a directory by manual methods provided the impetus to use computer techniques for the Fifth Edition. The account of the production of the first computer assisted Directory was described by S.C. Abrahams in the preface of the Fifth Edition. Computer composition, which required a machine readable data base, offered several major advantages. The choice of typeface and range of characters was flexible. Corrections and additions to the data base were rapid and, once established, it was hoped updating for future editions would be simple and inexpensive. The data base was put to other Union uses, such as preparation of mailing labels and formulation of lists of crystallographers with specified common fields of interest. The Fifth Edition of the World Directory of Crystallographers was published in June of 1977, the Sixth in May of 1981. The Subject Indexes for the Fifth and Sixth Editions were printed in 1978 and 1981 respectively, both having a limited distribution.

Available in PDF, EPUB and Kindle. Book excerpt: The art of chemistry is to thoroughly understand the properties of molecular compounds and materials and to be able to prepare novel compounds with p- dicted and desirable properties. The basis for progress is to fully appreciate and fundamentally understand the intimate relation between structure and function. The thermodynamic properties (stability, selectivity, redox potential), reactivities (bond breaking and formation, catalysis, electron transfer) and electronic properties (spectroscopy, magnetism) depend on the structure of a compound. Nevertheless, the discovery of novel molecular compounds and materials with exciting prop- ties is often and to a large extent based on serendipity. For compounds with novel and exciting properties, a thorough analysis of experimental data – state-of-the-art spectroscopy, magnetism, thermodynamic properties and/or detailed mechanistic information – combined with sophisticated electronic structure calculations is p- formed to interpret the results and fully understand the structure, properties and their interrelation. From these analyses, new models and theories may emerge, and this has led to the development of ef cient models for the design and interpre- tion of new materials and important new experiments. The chapters in this book therefore describe various fundamental aspects of structures, dynamics and physics of molecules and materials. The approaches, data and models discussed include new theoretical developments, computational studies and experimental work from molecular chemistry to biology and materials science.

Available in PDF, EPUB and Kindle. Book excerpt: Nel 1953 L. S. Miller riuscì a sintetizzare, per via abiotica, diverse sostanze organiche e tra queste parecchi amminoacidi, componenti delle nostre proteine. Questo esperimento sembrò anche una conferma della teoria del brodo prebiotico. La scoperta sollevò un grande entusiasmo tra gli scienziati e sembrava, in quel periodo, che in poco tempo sarebbe arrivata anche la sintesi della vita in provetta. Ben presto però alcuni ostacoli risultarono insormontabili e così dopo quasi 60 anni siamo ancora all'esperienza di Miller. Partendo da questo dato sperimentale l'autore, in questo saggio, presenta il risultato di 25 anni di ricerche sulla chimica prebiotica. In particolare illustra indizi sperimentali su: la selezione degli amminoacidi naturali e la scomparsa dell'amminoacido destro, l'origine di un codice genetico rudimentale e l'interdipendenza acidi nucleici-proteine. Questi dati ci indicano, che la vita ha avuto probabilmente origine sulla terraferma, che il brodo prebiotico non è mai esistito e inoltre sollevano anche seri dubbi sull'esistenza di un progenitore comune a tutti gli organismi viventi. Infine viene presentata la teoria sull'origine della vita.

Download or read book Transition Metals in Supramolecular Chemistry written by L. Fabbrizzi and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the pioneering publications on coordination chemistry by Lehn and Pedersen in the late 1960s, coupled with the more orthodox interest from the transition metal chemists on template reactions (Busch, 1964), the field of supramolecular chemistry has grown at an astonishing rate. The use of transition metals as essential constituents of multi-component assemblies has been especially sharp in recent years, since the metals are prone to quick and reversible redox changes, and there is a wide variety of metal--ligand interactions. Such properties make supramolecular complexes of transition metal ions suitable candidates for exploration as light--energy converters and signal processors. Transition Metals in Supramolecular Chemistry focuses on the following main topics: (1) metal controlled organization of novel molecular assemblies and shapes; (2) design of molecular switches and devices operating through metal centres; (3) supramolecular catalysts that mimic metalloenzymes; (4) metal-containing sensory reagents and supramolecular recognition; and (5) molecular materials that display powerful electronic, optoelectronic and magnetic properties.

Available in PDF, EPUB and Kindle. Book excerpt: The 9th edition of the World Directory of Crystallographers and of Other Scientists Employing Crystallographic Methods, which contains 7907 entries embracing 72 countries, differs considerably from the 8th edition, published in 1990. The content has been updated, and the methods used to acquire the information presented and to produce this new edition of the Directory have involved the latest advances in technology. The Directory is now also available as a regularly updated electronic database, accessible via e-mail, Telnet, Gopher, World-Wide Web, and Mosaic. Full details are given in an Appendix to the printed edition.
