TL;DR: The use of microwave radiation in glass processing is reviewed and compared to the usual processing techniques, such as glass melting, sintering, sealing, devitrification, coating, reinforcement with various substances, deposition by layers, etc.
Abstract: The use of microwave (MW) radiation in glass processing is reviewed and compared to the usual processing techniques, such as glass melting, sintering, sealing, devitrification, coating, reinforcement with various substances, deposition by layers, etc. MW heating is known as a much-faster process (requiring minutes rather than hours), yielding good product quality, in comparison with the prolonged conventional thermal treatment of glass precursors.

Abstract: Recent (2000–2009) achievements on ditopic ligands are reviewed. The ditopic ligands are mainly represented by N-, P-, O-, and S-containing organic molecules or their N, O-, N, S-, and N, P-combinations with azine, azole, amine, azide, β-diketone, crown ether, carboxylate, phenanthroline, oxazoline, phosphole, and thiophene moieties, among others. A series of mono- and polynuclear transition and f-metal complexes with these ligands, in particular cluster- and supramolecular unit-containing complexes, have been obtained and characterized spectroscopically and electrochemically.

Abstract: Nanostructures in the forms of varieties of vegetation are reviewed, in particular nanotrees and their agglomerates, nanobushes, nanomushrooms, nanoflowers, nanograss, and nanosheafs, among many others. Synthesis methods, influence of reaction conditions on the structural types of products, properties, formation mechanisms, and current and future applications are discussed. These nanostructures possess a series of useful properties (magnetic, semiconducting, field-emission, etc.) and applications, mainly in catalysis, as well as for creation of nanomaterials, solar cells, and in medicine for tumor treatments, among other uses.

TL;DR: In this article, the inner-chelate competitive metal binding of ambidentate ligand systems was investigated and the existence of octahedral nickel, zinc, and cadmium complexes containing four five-membered metallocycles with the N4О2 or N6 ligand environments was revealed.
Abstract: The chelates of 2-hydroxy(aminophenylnaphthyl)-azo-1-alkylbenzimidazoles were obtained from electrochemical (anodic dissolution of zero-valent d-metals) and chemical (from acetates of the same metals) syntheses in methanol. The EXAFS and X-ray single crystal diffraction data revealed the existence of octahedral nickel, zinc, and cadmium complexes containing four five-membered metallocycles with the N4О2 or N6 ligand environments. The formation of five-membered coordination units, non-typical for azo ligands, is explained on the basis of inner-chelate competitive metal binding of ambidentate ligand systems.

Abstract: Metal phthalocyanines were obtained at room temperature with the use of supported Cun/Al2O3 nanoparticles and active unstable complex Mg(anthracene) . 3THF in a series of protic and aprotic nonaqueous solvents (yields 511%). The properties of copperalumina aggregates were studied by mor- phological, atomic force microscopy, and X-ray diffraction studies. The phthalocya- nines as shown exist in the form of nanorods and nanowires having 80120 nm diameters, as shown by scanning electron microscopy studies.
