Vibrational Circular Dichroism Shows Reversible Helical Handedness Switching in Peptidomimetic l-Valine Fibrils
American Chemical Society (2012)We elucidate the supramolecular organization in the form of microsize fibrils of gels formed by a l-Valine peptidomimetic compound. Analysis was based on circular dichroism spectroscopies, vibrational (VCD) and electronic ... -
Vitrification and sinter-crystallization of fly ash with glass cullet
MedCrave (2019)The synthesis of a new glass-ceramic obtained by sinter-crystallization has been investigated by using soda-lime-silicate glass waste and fly ashes from a coal power thermal station located in Andorra (Teruel, Spain). ... -
Voltage-Dependent Bulk Resistivity of SrTiO3:Mg Ceramics
John Wiley & Sons (2014)Single phase ceramics of composition Sr(Ti1–xMgx)O3–x: 0 ≤ x ≤ 0.01 were prepared by sol–gel synthesis and characterized by X-ray diffraction, scanning electron microscopy, impedance spectroscopy, and current–voltage ... -
Voltage-Dependent Low-Field Bulk Resistivity in BaTiO3:Zn Ceramics
American Ceramic Society (2010-02)Ceramics of composition Ba(Ti1−xZnx)O3−x: 0.00003≤x≤0.01 exhibit modest semiconductivity, whose value is increased by up to two orders of magnitude under the action of a small dc bias voltage. The effect, which is not ... -
Wastewater treatment via H2O2 activation and 4-nitrophenol oxidation with iron-doped nickel-azolate frameworks
Elsevier B.V. (2024-08-01)An advanced oxidation heterogeneous process completely degrades 4-nitrophenol in weak acid ambient aqueous conditions using post-synthetically iron-doped nickel azolate frameworks. The framework crystallinity, porosity and ... -
Water Oxidation at Hematite Photoelectrodes with an Iridium-Based Catalyst
American Chemical Society (2013)The iridium complex [Cp*Ir(H2O)3](SO 4) was used as an organometallic source for the electrodeposition of iridium oxide onto Fe2O3. The new iridium-containing electrode allowed us to study the coupling between the ... -
Water-soluble IrIII n-heterocyclic carbene based catalysts for the reduction of CO2 to formate by transfer hydrogenation and the deuteration of aryl amines in water
WILEY-VCH Verlag (2011-03-01)Two new water-soluble [IrI2(AcO)(bis-NHC)] complexes (NHC=N-heterocyclic carbene) incorporating a sulfonate functionality have been synthesized. The two complexes have been tested in the reduction of CO2 with H2 and iPrOH, ... -
Y-Shaped Tris-N-Heterocyclic-Carbene Ligand for the Preparation of Multifunctional Catalysts of Iridium, Rhodium, and Palladium
American Chemical Society (2012)A series of homo- and hetero-dimetallic complexes of Ir, Rh, and Pd have been obtained using our previously reported Y-shaped tris-NHC ligand. The new complexes can be obtained through the isolation of the corresponding ... -
Zinc(II) coordination polymers with pseudopeptidic ligands
Royal Society of Chemistry (2011-10-11)Two new phenyl-bridged pseudopeptidic ligands have been prepared and structurally characterised. The nature of the ligands’ substituents play an important role in the nature of the solid state structure yielding either ... -
ZnO/Ag Nanocomposites with Enhanced Antimicrobial Activity
MDPI (2022-05-02)In this study, ZnO/Ag nanocomposites were synthesized using a facile chemical route involving metallic precursors of zinc acetate dehydrate and silver acetate, and dissolving the two metallic precursors in EtOH. The final ... -
ZnO/PVA Macroscopic Fibers Bearing Anisotropic Photonic Properties
Wiley-VCH (2012-10)Composite PVA/ZnO-nanorods fibers, synthesized through co-axial flux extrusion exhibit higher anisotropic photonic properties, both in absorption and emission, as a result of the collective alignment of the ZnO nanorods ... -
(η6-Arene)ruthenium(N-heterocyclic carbene) Complexes for the Chelation-Assisted Arylation and Deuteration of Arylpyridines: Catalytic Studies and Mechanistic Insights
Wiley-VCH (2010)A series of (η6-arene)ruthenium complexes have been tested in the arylation of arylpyridines. One (η6-p-cymene)ruthenium(N-heterocyclic carbene) complex (labelled as 1 in the text) was found to be the most effective, being ...
