Molecular Single‐Bond Covalent Radii for Elements 1–118Abstract A self‐consistent system of additive covalent radii, R (AB)=r (A) + r (B), is set up for the entire periodic table, Groups 1–18, Z =1–118. The primary bond lengths, R , are taken from experimental or theoretical data correspondin... ... hiện toàn bộ

Shape‐Controlled Synthesis of Metal Nanostructures: The Case of SilverAbstract The concept of shape‐controlled synthesis is discussed by investigating the growth mechanisms for silver nanocubes, nanowires, and nanospheres produced through a polymer‐mediated polyol process. Experimental parameters, such as the concentration of AgNO3 (the precursor to silver), the molar ratio between poly(vinylpyrrolidone) (PVP, the... ... hiện toàn bộ

Chemical and Structural Properties of Carbonaceous Products Obtained by Hydrothermal Carbonization of SaccharidesAbstract Carbon‐rich‐quick scheme : A carbon‐rich solid product made up of uniform micrometer‐sized spheres of tunable diameter has been synthesized by the hydrothermal carbonization of saccharides. These microspheres possess a core–shell chemical structure based on the different nature of the oxygen functionalities between the core and the out...

Ionothermal Synthesis of Crystalline, Condensed, Graphitic Carbon NitrideAbstract Herein we report the synthesis of a crystalline graphitic carbon nitride, or g‐C3 N4 , obtained from the temperature‐induced condensation of dicyandiamide (NH2 C(NH)NHCN) by using a salt melt of lithium chloride and potassium chloride as the solvent. The proposed crystal structure of this g‐C... hiện toàn bộ

Semiconductor Behavior of a Metal‐Organic Framework (MOF)Abstract Upon light excitation MOF‐5 behaves as a semiconductor and undergoes charge separation (electrons and holes) decaying in the microsecond time scale. The actual conduction band energy value was estimated to be 0.2 V versus NHE with a band gap of 3.4 eV. Photoinduced electron transfer processes to viologen generates the corresponding viologen radical cation, ... ... hiện toàn bộ

Synthesis, X‐ray Crystal Structures, and Gas Sorption Properties of Pillared Square Grid Nets Based on Paddle‐Wheel Motifs: Implications for Hydrogen Storage in Porous MaterialsAbstract A systematic modulation of organic ligands connecting dinuclear paddle‐wheel motifs leads to a series of isomorphous metal‐organic porous materials that have a three‐dimensional connectivity and interconnected pores. Aromatic dicarboxylates such as 1,4‐benzenedicarboxylate (1,4‐bdc), tetramethylterephthalate (tmbdc), 1,4‐naphthalenedicarboxylate (1,4‐ndc), ... ... hiện toàn bộ

Unmasking Melon by a Complementary Approach Employing Electron Diffraction, Solid‐State NMR Spectroscopy, and Theoretical Calculations—Structural Characterization of a Carbon Nitride PolymerAbstract Poly(aminoimino)heptazine, otherwise known as Liebig's melon, whose composition and structure has been subject to multitudinous speculations, was synthesized from melamine at 630 °C under the pressure of ammonia. Electron diffraction, solid‐state NMR spectroscopy, and theoretical calculations revealed that the nanocrystalline material exhibits domains well‐... ... hiện toàn bộ

Organocatalysis Mediated by (Thio)urea DerivativesAbstract Over the last decade the potential for N,N ‐dialkyl(thio)urea derivatives to serve as active metal‐free organocatalysts for a wide range of synthetically useful reactions susceptible to the influence of general acid catalysis has begun to be realised. This article charts the development of these catalysts (with emphasis on the desi... ... hiện toàn bộ

The Rich Stereochemistry of Eight‐Vertex Polyhedra: A Continuous Shape Measures StudyAbstract A stereochemical study of polyhedral eight‐vertex structures is presented, based on continuous shape measures (CShM). Reference polyhedra, shape maps, and minimal‐distortion interconversion paths are presented for eight‐vertex polyhedral and polygonal structures within the CShM framework. The application of these stereochemical tools is analyzed for several... ... hiện toàn bộ
