MnOx Nanoparticles Supported on a New Mesostructured Silicate with Textural Porosity
12-Apr-2010 | Nata[scaron]a Novak Tu[scaron]ar, Alenka Risti[cacute], Gregor Mali, Matja[zcaron] Mazaj, Iztok Ar[ccaron]on, Denis ..., Chemistry - A European Journal, 2010
A two-step synthesis of a novel mesostructured silicate, KIL-2, and its manganese-containing analogue, Mn/KIL-2, has been developed. KIL-2 possesses interparticle mesopores with pore dimensions between 5 and 60 nm and a surface area of 448 m2. The mesopores are formed by the aggregation of silica ...
Rapid Epitaxial Growth of Ag on Au Nanoparticles: From Au Nanorods to Core-Shell Au@Ag Octahedrons
06-Apr-2010 | Ana Sánchez-Iglesias, Enrique Carbó-Argibay, Arnaud Glaria, Benito Rodríguez-González, Jorge Pérez-Juste, Isabel Pas ..., Chemistry - A European Journal, 2010
Changing the shape of things to come! Au@Ag core-shell nanostructures with tailored morphology, ranging from nanorods all the way to spheres, through octahedrons (see picture), can be easily fabricated at room temperature through the selective reduction of Ag+ ions onto the surface of Au ...
On the Structural Chemistry of [gamma]-Brasses: Two Different Interpenetrating Networks in Ternary F-Cell Pd-Zn-Al Phases
01-Apr-2010 | Srinivasa Thimmaiah, Gordon J. Miller, Chemistry - A European Journal, 2010
Novel ternary phases, (Pd1-xZnx)18(Zn1-yAly)86-[delta] (0[le]x[le]0.162, 0.056[le]y[le]0.088, 0[le][delta][le]4), which adopt a superstructure of the [gamma]-brass type (called [gamma][prime]-brass), have been synthesized from the elements at 1120 K. Single-crystal X-ray structural analysis ...
Structural Analysis of a Helical Peptide Unfolding Pathway
31-Mar-2010 | Donatella Diana, Barbara Ziaco, Guido Scarabelli, Carlo Pedone, Giorgio Colombo, Luca D. D'Andrea, Roberto Fattorusso, Chemistry - A European Journal, 2010
The analysis of the folding mechanism in peptides adopting well-defined secondary structure is fundamental to understand protein folding. Herein, we describe the thermal unfolding of a 15-mer vascular endothelial growth factor mimicking [alpha]-helical peptide (QKL10A) through the combination of ...
Neutral and Oxidized Triisopropylsilyl End-Capped Oligothienoacenes: A Combined Electrochemical, Spectroscopic, and Theoretical Study
31-Mar-2010 | Juan Aragó, Pedro M. Viruela, Enrique Ortí, Reyes Malavé Osuna, Barbara Vercelli, Gianni Zotti, Víctor Hernández, Ju ..., Chemistry - A European Journal, 2010
This work presents an analysis of the structural, electrochemical, and optical properties of a family of triisopropylsilyl end-capped oligothienoacenes (TIPS-Tn-TIPS, n=4-8) by combining cyclic voltammetry, spectroscopic techniques, and quantum-chemical calculations. TIPS-Tn-TIPS compounds form ...
Lanthanide–Alkali Metal Sandwich Complexes: Synthesis, Structure, and Solvent‐Mediated Redox Transformations, and One‐Dimensional Frameworks Assembled through Cation–Arene π Interactions
06-Oct-2009 | Pan, Cheng‐Ling; Li, Xingwei; Zhang, Hongjie, Chemistry - A European Journal, 2009
Abstract Reaction of the potassium salt of amido ligand [Ph2Si(NAr)2]2− (L, Ar=2,6‐iPr2C6H3) and LnI2(thf)2 (Ln=Sm, Yb) gives sandwich complexes [(L)2Ln{K(Et2O)}2] (Ln=Sm (2), Yb (3)) with potassium–arene π interactions. Reaction of 2 with azobenzene gave the dimeric samarium cluster ...
Unstable Supramolecular Structure of [Bmim][BF4] in Aqueous Solution
22-Sep-2009 | Wu, Bo; Zhang, Li; Zhang, Yu Mei; Wang, Hua Ping, Chemistry - A European Journal, 2009
Abstract To unravel the exact composition and structure of aggregates in an aqueous solution of 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([Bmim][BF4]), we performed static and dynamic light‐scattering measurements, as well as transmission electron microscopy (TEM). Results from this work ...
