Based on H/D isotope exchange studies devoted to the quantification of the number of Brønsted acid sites in solid acids, we report herein an innovative approach to determine the amount of silver cations present in Keggin-type polyoxometalates (POM). The molecular design of these bifunctional heteropolyacids can theref…
We used CaCl 2 and NH 4 F from Merck Company for synthesis CaF 2 NPs.We synthesized CaF 2 Nanoparticales (NPs) using Co-precipitation and hydrothermal method successfully.The synthesized NPs were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Transmission Electron Microscopy…
We report for the first time the synthesis of CdSe@Fe2O3 core/shell nanoparticles by a one-step seeded-growth approach. These nanoparticles not only retain their individual semiconducting and magnetic functionalties, but also exhibit some new properties which are affected by the coating components. These bifunctional…
A dispersion of a peptide amphiphile into water forms hierarchical fibril structures, leading to a supramolecular hydrogel. We here report that there exists dynamic heterogeneity in the gel, which might be induced by the heterogeneous fibril network. The network, and therefore, the heterogeneity, can be easily regulat…
Differential separation and label-free detection of proteins using SERS from their mixtures after a convective assembly process is reported. Binary and ternary mixtures of proteins are mixed with AgNPs and assembled into ordered structures. The spectra acquired from the assembled area indicate that the proteins are di…
Based on the density functional theory (DFT), we evaluate the effect of sulfur impurity on the stability of cubic zirconia (c-ZrO2) and its interfaces with metals (Ni, Cu). It is observed that, at low concentration, sulfur atoms have the tendency to locate at the zirconia surface, while at high concentration (∼23.0 wt…
We demonstrate a conceptually novel approach to incorporate biological substrates with synthetic nanowires. Vertically aligned single crystal ZnO nanowire arrays were directly grown on the lotus leaf surface using a simple hydrothermal method. We observed a strong adhesive superhydrophobicity on this artificial/natura…
The use of edible films to release antimicrobial constituents in food packaging is a form of active packaging that contributes to extend the shelf-life of a product and provides microbial safety for consumers. A number of plant and animal proteins have been investigated for the production of edible films such as corn…
Magnetic Fe(2)O(3) nanorods with low cell toxicity were successfully synthesized via a wet-chemical method. In vivo studies with a rabbit model show that the nanorods exhibit excellent T(2) signal enhancement. This work demonstrates that magnetic nanorods may provide a new type of MR enhancement agent for use in biome…
A series of europium(III) complexes with different chain length, tris [2-m-pyridylmethanamido-5-phenyl- (1,3,4)-oxadiazole] mono [2-(4-n-alkylphenyl)-iminazole (4,5-f)-1,10-phenanthroline] Eu(III) [Eu(PMA)3Nn (n = 6, 10, 14,18)] were synthesized. All of these amphiphilic europium(III) complexes could form stable Langm…
Single-crystal nanofibers of a new structured PbTiO3 with Zr doping concentration of 0–15% have been reproducibly synthesized on a large scale by a polymer-assisted hydrothermal method for the first time. Moreover, the Zr-doped new structured PbTiO3 nanofibers can transform into single-crystalline perovskite Pb(Zr, Ti…
A new liquid-phase bonding method was developed to establish a strong bonding between Al bearing Mg alloys and steels by intentionally forming a thin and uniform reaction layer at the bonding interface. By adopting Ag as an interlayer between the Mg alloys and steel, Mg-Ag eutectic melt is produced at 773 K and nano-s…
Three commercial sugar substitutes (acesulfame K, cyclamate and saccharin), a bitterness inhibitor (ferulate) and a flavour potentiator (theobromine) have been intercalated into three common layered double hydroxide (LDH) hosts ([Ca2Al(OH)6]NO3·yH2O, [LiAl2(OH)6]Cl·yH2O and [Mg2Al(OH)6]NO3·yH2O) by ion exchange. These…
In this study, the morphology, orientation, as well as the mechanical and barrier properties of monolayer and multilayer nanoclay filled polypropylene (PP) obtained from the film blowing process were investigated. A significant alignment of nanoclay along the flow direction was observed from scanning electron microsco…
To increase the lifetime of molten carbonate fuel cell (MCFC) stacks, a reduction of the operating temperature is needed without decreasing the cell performance. In this study, a Ag coating on a conventional NiO cathode material of MCFC was carried out to enhance the cathode performance at the relatively low operating…
Reactions of the precursors [Ni(macrocyclic ligand)](2+) with [W(CN)(8)](3-) afford two octacyanotungstate-based assemblies, (H(2)L(1))(0.5)[Ni(L(1))][W(CN)(8)]·2DMF·H(2)O (L(1) = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) (1) and [Ni(L(2))](3)[W(CN)(8)](2)·4H(2)O (L(2) = 3,10-dipropyl-1,3,5,8,10,12-…
In this work, geometrical optimizations of Ag disc on pillar (DOP) hybrid plasmonic nanostructures were conducted and allowed us to achieve reproducible average enhancement factors of 1 × 10(9) and greater.
A family of layered lanthanide (Pr, Nd, Sm, Eu, and Gd) hydroxide nanowires (NWs) has been synthesized via a hydrothermal route. These NWs are ∼8 nm in diameter and a few micrometres in length. The obtained Eu- and Gd-based layered hydroxide NWs consist of layered structure with two interlayer spacings. The effects of…
Nanodiamond/polyacrylonitrile (PAN) thick-film composites containing aggregated ultra-dispersed (UDD) and highly de-aggregated nanodiamond (ND) fillers are fabricated using bead-milling and solution-casting methods at additive loadings up to 30 wt%. Films containing oxidized nanodiamond fillers (ox-UDD and ox-ND) havi…
Controllably constructing hierarchical nanostructures with distinct components and designed architectures is an important theme of research in nanoscience, entailing novel but reliable approaches of bottom-up synthesis. Here, we report a facile method to reproducibly create semiconductor-insulator-metal core/shell nan…
