TL;DR: The bonding properties of thiocyanate groups of over one hundred copper species, studied by X-ray analysis, were analyzed in this paper, where it was shown that the bonding properties depend on the size of the positive charge on the copper atom.

TL;DR: In this paper, the authors summarized the data for over nine hundred dimeric Cu(II) coordination compounds and found that the most common ligands are O− and N− donors.
Abstract: This review summarizes the data for over nine hundred dimeric Cu(II) coordination compounds. There are several types of the bridges, from which doubly bridges by far prevail. The most common ligands are O− and N− donors. From the stereochemical point of view, a square-pyramidal arrangement with different degrees of distortion about Cu(II), is the most common. Several relationships were found between the Cu-Cu distances and the Cu-L-Cu bridge angle and the type of bridging, between the intra-ligand L-Cu-L ring angles and coordination numbers.

TL;DR: A comprehensive review of current research activities that center on the shape-controlled synthesis of metal nanocrystals, including a brief introduction to nucleation and growth within the context of metal Nanocrystal synthesis, followed by a discussion of the possible shapes that aMetal nanocrystal might take under different conditions.
Abstract: Nanocrystals are fundamental to modern science and technology. Mastery over the shape of a nanocrystal enables control of its properties and enhancement of its usefulness for a given application. Our aim is to present a comprehensive review of current research activities that center on the shape-controlled synthesis of metal nanocrystals. We begin with a brief introduction to nucleation and growth within the context of metal nanocrystal synthesis, followed by a discussion of the possible shapes that a metal nanocrystal might take under different conditions. We then focus on a variety of experimental parameters that have been explored to manipulate the nucleation and growth of metal nanocrystals in solution-phase syntheses in an effort to generate specific shapes. We then elaborate on these approaches by selecting examples in which there is already reasonable understanding for the observed shape control or at least the protocols have proven to be reproducible and controllable. Finally, we highlight a number of applications that have been enabled and/or enhanced by the shape-controlled synthesis of metal nanocrystals. We conclude this article with personal perspectives on the directions toward which future research in this field might take.

TL;DR: The state of the art in the field of antimicrobial polymeric systems during the last decade is described in this paper, where a classification of the different materials is carried out dividing basically those synthetic polymers that exhibit antimicrobial activity by themselves; those whose biocidal activity is conferred through their chemical modification; those that incorporate antimicrobial organic compounds with either low or high molecular weight; and those that involve the addition of active inorganic systems.
