TL;DR: ZnO doughnut-like cluster particles were prepared by a simple solvothermal route using an ethylene glycol (EG)−water solvent system as mentioned in this paper, and they were obtained when an equal or higher volume fraction of EG was used in the solvent.
Abstract: ZnO doughnutlike cluster particles were prepared by a simple solvothermal route using an ethylene glycol (EG)−water solvent system. It was observed that ZnO doughnuts were obtained when an equal or higher volume fraction of EG was used in the solvent. Microstructural studies revealed that these doughnut-shaped particles were clusters of small hexagonal plates arranged in a regular fashion. Because of the capping property of EG, these constituent hexagonal plates arranged in an angular oriented attachment scheme with a view to minimize their surface energies. The resulting assemblies were concave from one side and convex from the reverse side. With the increasing percentage of EG, the concentration of the capping element increased, resulting in the reduction of the size of the constituent plates, which in turn helps the formation of more and more densely packed ZnO doughnuts. Increases in temperature and pressure also favor the formation of densely packed ZnO doughnuts. These ZnO samples exhibited a strong...

TL;DR: In this paper, a polymer nanocomposites of poly(3-hexylthiophene) (P3HT) with organically modified montmorillonite (om-MMT) clay have been prepared by the solvent casting method.
Abstract: Polymer nanocomposites (PNCs) of poly(3-hexylthiophene) (P3HT) with organically modified montmorillonite (om-MMT) clay have been prepared by the solvent casting method. WAXS and TEM studies indicate exfoliated clay structure for lower clay content, but at higher clay content (5%, w/w) intercalated structures appear. The interchain lamella of P3HT exists in the nanocomposite, and the P3HT crystals become more ordered, showing better X-ray diffraction peaks. The thermal stability of PNCs increases significantly, and 1% clay content PNC exhibits the maximum thermal stability. The glass transition temperature (Tg), β-transition temperature (Tβ), the melting point (Tm), and the enthalpy of fusion (ΔH) of the PNCs are increased as compared to those of pure P3HT. The storage modulus (G‘) of PNCs showed a dramatic increase from that of pure P3HT, and the increase is larger in the temperature range 20−50 °C. The FTIR study indicates a decrease in Si−O−Si and Si−O stretching frequency for the exfoliated clay struct...

TL;DR: The absorption spectra, redox behavior, and luminescence properties of the ruthenium(II) complexes have been thoroughly investigated, and it has been observed that the metalloreceptors act as sensors for F(-, AcO(-), and to some extent H(2)PO(4)(-).
Abstract: A series of heteroleptic tridentate ruthenium(II) complexes of composition [(H2pbbzim)Ru(tpy-X)](PF6)2 (1−7), where H2pbbzim = 2,6-bis(benzimidazole-2-yl)pyridine and tpy-X = 4′-substituted terpyridine ligands with X = H, p-methyl phenyl (PhCH3), p-bromomethylphenyl (PhCH2Br), p-dibromomethylphenyl (PhCHBr2), p-cyanomethylphenyl (PhCH2CN), p-triphenylphosphonium methylphenyl bromide (PhCH2PPh3Br), and 4′-phenylformyl (PhCHO) groups, has been synthesized and characterized by using standard analytical and spectroscopic techniques. These compounds were designed to increase the excited-state lifetime of ruthenium(II) bisterpyridine-type complexes. The X-ray crystal structure of a representative compound 2, which crystallized with monoclinic space group P2(1)/c, has been determined. The absorption spectra, redox behavior, and luminescence properties of the ruthenium(II) complexes have been thoroughly investigated. All of the complexes display moderately strong luminescence at room temperature with lifetimes in...
