TL;DR: The first example of a rationally designed metallacycle, the molecular square [{Pd(en)(μ-4,4′-bipy)}4](NO3)8, was described by self-assembly of the cis-protected square-planar Pd(II) precursor with two adjacent labile ligands.
Abstract: In 1990, Fujita and co-workers described the first example of a rationally designed metallacycle, the molecular square [{Pd(en)(μ-4,4′-bipy)}4](NO3)8, prepared by self-assembly of the cis-protected square-planar Pd(II) precursor with two adjacent labile ligands [Pd(en)(ONO2)2] (en ) ethylenediamine) with the linear linker 4,4′-bipyridine (4,4′-bipy). Since then, supramolecular chemistry has produced an amazing number of fascinating 2D and 3D metal-mediated molecular architectures, including many macrocycles and cages. Several review articles have thoroughly covered this thriving field in recent years. Beside their shared structural beauty, some of these assemblies are finding applications as receptors and molecular vessels for trapping reactive intermediates, as well as for stoichiometric and catalytic reactions.

TL;DR: Geringe Katalysatormengen und kurze Reaktionsdauer genugen zur quantitativen Reduktion von Ketonen durch 2-Propanol und den Komplex [RuX(CNN)(dppb)], dessen dreizahniger Ligand sich von 6-(4-Methylphenyl)-2-pyridylmethylamin ableitet.
Abstract: Geringe Katalysatormengen und kurze Reaktionsdauer genugen zur quantitativen Reduktion von Ketonen durch 2-Propanol und den Komplex [RuX(CNN)(dppb)] (siehe Struktur; X=H, Cl), dessen dreizahniger Ligand sich von 6-(4-Methylphenyl)-2-pyridylmethylamin ableitet. Die Reduktion scheint uber eine reversible Insertion des Substrats in die Ru-H-Bindung zu verlaufen, bei der ein RutheniumII)-alkoxid entsteht. dppb=Ph2P(CH2)4PPh2.

TL;DR: This volume is keyed to high resolution electron microscopy, which is a sophisticated form of structural analysis, but really morphology in a modern guise, the physical and mechanical background of the instrument and its ancillary tools are simply and well presented.
Abstract: I read this book the same weekend that the Packers took on the Rams, and the experience of the latter event, obviously, colored my judgment. Although I abhor anything that smacks of being a handbook (like, \"How to Earn a Merit Badge in Neurosurgery\") because too many volumes in biomedical science already evince a boyscout-like approach, I must confess that parts of this volume are fast, scholarly, and significant, with certain reservations. I like parts of this well-illustrated book because Dr. Sj6strand, without so stating, develops certain subjects on technique in relation to the acquisition of judgment and sophistication. And this is important! So, given that the author (like all of us) is somewhat deficient in some areas, and biased in others, the book is still valuable if the uninitiated reader swallows it in a general fashion, realizing full well that what will be required from the reader is a modulation to fit his vision, propreception, adaptation and response, and the kind of problem he is undertaking. A major deficiency of this book is revealed by comparison of its use of physics and of chemistry to provide understanding and background for the application of high resolution electron microscopy to problems in biology. Since the volume is keyed to high resolution electron microscopy, which is a sophisticated form of structural analysis, but really morphology in a modern guise, the physical and mechanical background of The instrument and its ancillary tools are simply and well presented. The potential use of chemical or cytochemical information as it relates to biological fine structure , however, is quite deficient. I wonder when even sophisticated morphol-ogists will consider fixation a reaction and not a technique; only then will the fundamentals become self-evident and predictable and this sine qua flon will become less mystical. Staining reactions (the most inadequate chapter) ought to be something more than a technique to selectively enhance contrast of morphological elements; it ought to give the structural addresses of some of the chemical residents of cell components. Is it pertinent that auto-radiography gets singled out for more complete coverage than other significant aspects of cytochemistry by a high resolution microscopist, when it has a built-in minimal error of 1,000 A in standard practice? I don't mean to blind-side (in strict football terminology) Dr. Sj6strand's efforts for what is \"routinely used in our laboratory\"; what is done is usually well done. It's just that …
