Cobalt( <sc>ii</sc> )/conducting polymer/montmorillonite composites are synthesized through ion exchange of montmorillonite (MMT) followed by oxidative polymerization using Co( <sc>iii</sc> ) as the oxidant. Composites are characterized and used as electrocatalysts.
was observed as well as the co-extraction of water molecules, suggesting a self-association of the extractant. The proposed liquid-liquid extraction generic system paves the way for innovative niobium (and potentially tantalum) hydrometallurgical processes and it may also afford more direct routes for exploring the ch…
For supported metal nanoparticles, the ligand/support is crucial to their catalytic activity, stability and recyclability.
Lateral diffusion of cyclic polystyrene at the interface between fused silica and dichloromethane is investigated at the single-molecular level. Narrowly distributed cyclic polystyrene (c-PS) of high purity with molecular weights spanning nearly an order of magnitude is prepared via atom transfer radical polymerizatio…
The novel dendritic-shaped, heptanuclear compound 1 - the first mixed Os-Ru dendrimer with tris-chelating bridging ligands - has been synthesized and its photophysics studied by fs pump-probe transient spectroscopy. In 1, all light energy absorbed by six identical Ru(ii) chromophores is funnelled to the luminescent ce…
The Nevirapine (NVP)/Polycaprolactone (PCL)/Nanoparticles hybrids systems have been developed as a potential platform for drug delivery, by solvent cast, as thin films. NVP, an antiretroviral drug, was included within PCL matrix containing three types of nanoparticles: an organoclay layered silicate Viscogel S7®(3% w/…
Cr( <sc>iii</sc> ) is observed to prefer (near-)surface sites in boehmite, as opposed to the bulk.
High-resistivity β -Ga 2 O 3 thin films were grown on Si-doped n-type conductive β -Ga 2 O 3 single crystals by molecular beam epitaxy (MBE). Vertical-type Schottky diodes were fabricated, and the electrical properties of the Schottky diodes were studied in this letter. The ideality factor and the series resistance of…
The adhesion of two materials in the presence of water is greatly impeded by a boundary layer of water between the adhesive and the adherend, resulting in adhesive failure of most synthetic adhesives; however, life evolved first in water and there are many aquatic organisms that have to overcome this impediment to und…
The facile tuning of the fluorescent properties of organogels is highly desirable for optical switches, light-emitting diodes, chemosensors and bioprobes. The design of organic molecules with multiple emission colors but only one molecular platform remains challenging. Herein, a new cholesterol-based organogelator N1…
precursor. The final products can take different surface structures (concave vs. flat side faces) depending on the presence or absence of surface capping.
The ground state geometries of neutral and anionic lanthanide-metal-doped silicon clusters Si <sub>7</sub> M <sup>0/−</sup> with M = Pr, Gd and Ho were determined by quantum chemical (DFT) computations and the previous experimental photoelectron spectra were assigned.
We report the fabrication of platinum nanostructures on an ITO substrate (Pt-NSs).
Herein, we demonstrate the influence of zirconium species on promoting the oxygen storage capacity and three-way catalytic properties of zirconium-manganese oxide catalysts.
The trapping/detrapping processes and persistent energy transfer in a new cyan afterglow phosphor α-Ca <sub>3</sub> (PO <sub>4</sub> ) <sub>2</sub> :Eu <sup>2+</sup> ,Dy <sup>3+</sup> .
Fluorescent carbon nanodots were used as a sensitive, biocompatible intracellular pH sensor that can resolve minor pH differences in live cells.
We report the first supramolecular engineering polymer with melt viscosity suitable for non-degradative processing plus enhanced thermal and mechanical properties.
Direct purification of twist-spun single-walled carbon nanotube (SWNT) fibers by applying an instantaneous high current through the fiber.
This paper explores the synthesis of a series of prototype negative dielectric liquid crystalline (LC) compounds which contain fluorinated cyclohexane motifs. The series are analogues and differ only in that they contain between one to four fluorine atoms. The stereochemistry is such that all of the fluorines/C-F bond…
A partially-wetting sessile drop is driven by a sinusoidal pressure field that produces capillary waves on the liquid/gas interface. Response diagrams and phase shifts for the droplet, whose contact-line moves with contact-angle that is a smooth function of the contact line speed, are reported. Contact-line dissipatio…
