The layered perovskite LaTaO(4) has been prepared in its polar orthorhombic polymorphic form at ambient temperature. Although no structural phase transition is observed in the temperature interval 25° C < T < 500 °C, a very large axial thermal contraction effect is seen, which can be ascribed to an anomalous buckling…
In this study composite nanofibres of PVA consisting of polystyrene/ <italic>n</italic> -octadecane nanocapsules were prepared.
A rhodamine appended hexaphenylbenzene based derivative <bold>5</bold> has been designed and synthesized, which displays through bond energy transfer in the presence of picric acid in MeOH and serves as a "turn on" sensor for picric acid.
Carbon-polymer composites have great application potential in the field of organic batteries, capacitors, capacitive water desalination reactors and as the conductive platforms for electrochemical sensors. Although numerous studies have been carried out with respect to the synthesis, the optimization of composition, t…
Zinc oxide (ZnO) nanorods have been synthesized by solution processing hydrothermal method in low temperature using the spin coating technique. Zinc acetate dehydrate, Zinc nitrate hexahydrate and hexamethylenetetramine were used as a starting material. The ZnO seed layer was first deposited by spin coated of ethanol…
We adopted molecular dynamics simulation to study the conductive property of nanorod-filled polymer nanocomposites by focusing on the effects of the interfacial interaction, aspect ratio of the fillers, external shear field, filler-filler interaction and temperature. The variation of the percolation threshold is anti…
The directional-freezing construction of elastic ionogel electrolytes is described, offering an effective approach to attain aligned structures and enhanced electrochemical properties for energy storage devices.
The effects of size, shape, surface ligands and oxygen exposure time on the localized surface plasmon resonance absorption in monoclinic djurleite nanocrystals have been demonstrated.
An overview of the chemistry of isoporphyrin, the tautomer of porphyrin, whose existence was predicated by the Noble laureate Woodward, is presented with emphasis on hydroxy-isoporphyrins of tetra-aryl derivatives. The chemistry of metalloisoporphyrin has been discussed since the discovery of the first metallo-isoporp…
The structural, electronic, and magnetic properties of rare‐earth metals doped ZnO monolayer have been investigated using the first‐principles calculations. The induced spin polarization is confirmed for Ce, Eu, Gd, and Dy dopings while the induced spin polarization is negligible for Y doping. The localized f states o…
Linseed polyol/ZnO bionanocomposite produced strong, well-adherent, flexibility-retentive, thermally stable, hydrophobic, “green” corrosion protective coatings <italic>via</italic> an <italic>in situ</italic> solventless “green” approach.
The detection of boron-containing compounds requires very expensive facilities and/or tedious sample pretreatments. In an effort to develop a convenient detection method for boronic acid derivatives, boron chelating-ligands were synthesized for use as fluorescent sensors. In this paper, the synthesis and properties of…
The effect of interlayer anions on the photoluminescence of layered rare earth hydroxides was investigated with Eu <sup>3+</sup> , Tb <sup>3+</sup> , and Ce <sup>3+</sup> -doped layered gadolinium hydroxynitrate as a representative base matrix for efficient and stable anion-exchange reactions.
Upconversion nanoparticle and gold nanorod heteronanostructures spaced by a polyelectrolyte are prepared by a layer-by-layer assembly process to enhance red emission.
HZSM-5 zeolite was prepared by alkali treatment and NH <sub>4</sub> <sup>+</sup> -exchange, followed by modification with cobalt nitrate and lanthanum nitrate <italic>via</italic> impregnation.
The Zintl phase Eu <sub>5</sub> In <sub>2−x</sub> Zn <sub>x</sub> Sb <sub>6</sub> ( <italic>x</italic> = 0, 0.025, 0.05, 0.1, 0.2) with optimized p-type carrier concentration displays a <italic>zT</italic> of up to 0.4 at ∼660 K.
Sol-gel hybrids are inorganic/organic co-networks with nanoscale interactions between the components leading to unique synergistic mechanical properties, which can be tailored, via a selection of the organic moiety. Methacrylate based polymers present several benefits for class II hybrids (which exhibit formal covalen…
Highly uniform single-crystalline Bi <sub>19</sub> S <sub>27</sub> (Br <sub>3−x</sub> ,I <sub>x</sub> ) alloyed nanowires (NWs) (0 ≤ <italic>x</italic> ≤ 3) were achieved for the first time. The NWs show a composition-independent band gap and have great application potential in optoelectronic devices.
PEGylated SPIONs using PEG MWs from 1500 to 8000 were intravenously injected in mice. Parametric MRI allowed us to track the pharmacokinetics and determine the effect of MW on the biodistribution and circulation times of PEG-SPIONs (HD < 50 nm).
Gamma radiation has been shown particularly useful for the functionalization of surfaces with stimuli-responsive polymers. This method involves the formation of active sites (free radicals) onto the polymeric backbone as a result of the exposition to high-energy radiation, in which a proper microenvironment for the re…
