Here, we demonstrate the synthesis of Sm 2 O 3 nanoparticles, nanorods and nanoplates by solution-based techniques. The mechanism related to morphology control is proposed and discussed. The crystal phase of the Sm 2 O 3 nanocrystal is tuned by varying the surfactant in the reaction. It is found that compressive strai…
At the interface of LaAlO3/SrTiO3 with film thickness of 3 unit cells or greater, a reproducible electric-field-induced bipolar resistance switching of the interfacial conduction is observed on nanometer scale by a biased conducting atomic force microscopy under vacuum environment. The switching behavior is suggested…
Three new novel palladium(II) iodates with square-planar PdO(4) units, namely, Pd(IO(3))(2), AgPd(IO(3))(3), and BaPd(IO(3))(4), have been successfully hydrothermally synthesized. They represent the first ternary and quaternary palladium(II) iodates and display three different structural types. Pd(IO(3))(2) exhibits a…
In the last decade, substantial research in the field of post-plasma grafting surface modification has focussed on the introduction of carboxylic acids on surfaces by grafting acrylic acid (AAc). In the present work, we report on an alternative approach for biomaterial surface functionalisation. Thin poly-ε-caprolacto…
Rational design of robust nanocatalysts for CO oxidation and NO x reduction is crucial for many important applications such as pollution control and energy production. Owing to its particular redox properties, ceria has been extensively utilized in catalytic converters [ 1 , 2 ]. Significantly, its redox performance c…
Inequivalent angular distributions have been found for La and Al in the ablation plume from LaAlO3 single crystal targets using a KrF laser during pulsed laser deposition. Angular distributions and stoichiometries in the condensate were measured and reveal decidedly nonstoichiometric transfer from target to substrate…
A straightforward functionalization of a titanium surface using "click" chemistry is reported. A "clickable" titanium surface platform was prepared by the immobilization of an azide-functionalized electroactive catechol anchor and was subsequently derivatized with an electroactive or fluorinated probe via the CuAAC (c…
Two one-dimensional (1D) cyanide- and phenolate-bridged heterotrimetallic complexes {[Cu II Mn II (L 1 )][Fe III (bpb)(CN) 2 ]} n ·(ClO 4 ) n ·(H 2 O) n ( 1 ) and {[Cu II Mn II (L 1 )][Cr III (bpb)(CN) 2 ]} n ·(ClO 4 ) n ·(H 2 O) n ( 2 ) (bpb 2− = 1,2-Bis(pyridine-2-carboxamido)benzenate) have been designed and prepar…
Highly ordered freestanding honeycomb films with asymmetric through-pore structures were prepared from polystyrene/gold-nanoparticles (PS/AuNPs) nanocomposite at an air/water interface using a one-step interfacial self-assembly method.
The effect of underlayer thin films on the sensitivity of Ag nanorod surface-enhanced Raman scattering (SERS) substrates was studied both theoretically and experimentally. With the same Ag nanorod film, different materials (Ag, Al, Si, and Ti) with different thicknesses (25, 100, and 400 nm) were used as underlayers t…
Abstract Advances in the growing use of polymer composites in aerospace applications explore the possibility in the development of smart materials capable of self‐repair. In this article, we have formulated and characterized a multifunctional autonomically healing composite inspired by the design of White et al. Micro…
On the basis of density functional calculations we explored the possibility that BN and ZnO single layers can become ferromagnetic at room temperature and half-metallic upon fluorine adsorption. Fluorine atoms form stable bonds only with the B and Zn atoms on the graphenelike BN and ZnO single layers, respectively, an…
Single phase Bi2FeMnO6 was synthesized on Si substrates by an electrospray method. Three peaks were observed in the temperature dependence of magnetization curve, which is attributed to the inhomogeneous distribution of Fe3+ and Mn3+. The observed magnetic peaks at 150 K, 260 K, and 440 K correspond to orderings of th…
Our objective was to demonstrate the effect of various processing factors on the performance of a microfiltration system designed to process skim milk and separate casein (CN) from serum proteins (SP). A mathematical model of a skim milk microfiltration process was developed with 3 stages plus an additional fourth fin…
In conduction, thermal rectification occurs when a material or structure transfers heat asymmetrically. In this work, it is shown that, in the bulk, a necessary condition for thermal rectification is that the thermal conductivity of the material or structure be a function of both space and temperature, and that this f…
All for one and one for all: Molecules with multiple conjugated photochromic boryl units undergo photoisomerization on a single boryl unit only. This single boryl switching causes fluorescence quenching of the entire molecule, which is greatly amplified with increasing numbers of switchable boryl units in the molecule.
A new dynamic model of a three-phase three-leg transformer for steady-state and transient operating conditions is proposed in this paper. With very few exceptions, the existing models oversimplify the magnetic interactions in multileg core topologies and employ single-value nonlinear functions for modeling core nonlin…
Abstract Magnetic nanocomposites were prepared by an in situ oxidative polymerization method to encapsulate different loadings of iron oxide nanoparticles (MNP) by a conductive polymer, polypyrrole (PPy), and were blended into an epoxy resin matrix. The morphology, DC conductivity, magnetic, and electromagnetic interf…
ZnO thin films were grown on Si or <TEX>$SiO_2$</TEX>/Si substrates, at growth temperatures ranging from 150 to <TEX>$400^{\circ}C$</TEX>, by atomic layer deposition (ALD) using diethylzinc and water. Despite the large band gap of 3.3 eV, the ALD ZnO films show high n-type conductivity, i.e. low resistivity in the ord…
The solubility of butyl paraben (butyl 4-hydroxybenzoate) have been determined in methanol, ethanol, propanol, acetone, ethyl acetate, and acetonitrile in the temperature range of (10 to 50) °C by the gravimetric method. The order of the solubility of butyl paraben in the different solvents as mass fraction at 20 °C i…
