X-ray absorption near edge structure (XANES) and electrical measurements were used to elucidate the local structure and electronic changes of copper(II) oxide (CuO) nanostructures under working conditions. For this purpose, a sample holder layout was developed enabling the simultaneous analysis of the spectroscopic an…
Fe <sub>3</sub> O <sub>4</sub> /C nanocomposites with relatively high superparamagnetic and ferromagnetic performances were obtained by an ultrasound method combining calcination, which provided promising applications for the dye removal and wastewater treatment fields.
Impurity doping has yielded a number of useful optical and catalytic alloy nanoparticles, by providing synthetic routes to unprecedented nanostructures. However, Zn is difficult to use as a dopant in alloy nanoparticles due to the difficulty in reduction, and therefore little has been reported on Zn-doped alloy nanopa…
Spectroscopy characterization on a phosphorous doped graphene layer suggests p-type doping governed by an electron transfer mechanism with a cupper substrate.
In this work, an external magnetic field was utilized during the thermal decomposition process to manipulate the shapes, surfaces and magnetic properties of Fe3O4 nanoparticles. The applied magnetic field of 500 Oe induced the formation of uniform Fe3O4 nanocubes of 250 nm, in sharp contrast to the nanocuboctahedra fo…
We report on a rapid and selective fluorescence turn-on detection system for Cu <sup>2+</sup> based on the formation of highly fluorescent copper nanoclusters (CuNCs).
A new rigid and conjugated ligand structure connecting phenanthroline and poly(amino-carboxylate) binding sites provides d-f complexes which show high potential for use in dual (luminescence + magnetic resonance) imaging and for optimisation of d → f photoinduced energy-transfer.
A stimulus-free self-healing conductive composite with a sushi-like structure composed of hyperbranched poly(amido amine)s and carbon nanotubes exhibits excellent ability for the restoration of structural integrity and conductivity without any external stimuli and with no precise alignment of conductive pathways.
We show how a combination of near- and far-field coupling of the localised surface plasmon resonances in aluminium nanoparticles deposited on TiO2 films greatly enhances the visible light photocatalytic activity of the semiconductor material. We demonstrate two orders of magnitude enhancement in the rate of decomposit…
Past research efforts aiming at obtaining stable p-type ZnO have been based on complexes involving nitrogen doping. A recent experiment by (J. G. Reynolds et al., Appl. Phys. Lett., 2013, 102, 152114) demonstrated a significant (∼10(18) cm(-3)) p-type behavior in N-doped ZnO films after appropriate annealing. The p-ty…
Photocatalytic efficiency of unsubstituted ZnO is greater than Li substituted ZnO nanorods due to the presence of defect states and higher charge carrier density.
(1) Synthesis: an evolution mechanism of NSCC-Bi <sub>2</sub> Fe <sub>4</sub> O <sub>9</sub> <italic>via</italic> a delicate synthesis processes; (2) application: visible-light photo-Fenton oxidation for organic pollutant removal and (3) multiplex catalysis: its catalytic mechanism in light or dark conditions.
A series of luminescent L-valine modified alkynyl-based cyclometalated gold(III) complexes are synthesized and characterized. Through a balance of π–π stacking, hydrogen bonding and hydrophobic–hydrophobic interactions, organogelation of the gold(III) complexes is achieved in DMSO. The gelation properties of the compl…
Use of organometallic polymers assists in clarifying relevant structure–property–function relationships in multicomponent systems such as semiconductor:insulator blends.
Co-precipitation <italic>cum</italic> modified Stöber method is a continuous process avoiding application of higher temperature treatment before supporting nanometals with SiO <sub>2</sub> , irrespective of pre-preparation methods.
H two-dimensional NMR. Flurbiprofen molecules are molecularly dispersed inside polypropylene cores of P123 surfactant micelles occluded in a 20-30 nm thick silica shell. Flurbiprofen molecules in polypropylene cores of P123 micelles exhibit high mobility and are easily released after introduction in simulated gastroin…
Developing new materials or modifying the existing ones is an amply field studied in the world of research. Due to its outstanding physical and chemical properties, graphene is attractive material for new applications. The methodologies for obtaining graphene are diverse and have changed over time. Graphene oxide is a…
PNIPAM & CDs composites have been used as a sensor of temperature. At around 32 °C, the fluorescent intensity decrease sharply because of CDs' self-quenching effect.
In accelerator driven systems (ADSs), steels will suffer not only from the irradiation damage produced by protons or neutrons, but also from the dissolution corrosion induced by the liquid lead-bismuth eutectic (LBE). In this work we investigate the interactions between LBE atoms (Pb, Bi) and the irradiation induced d…
A novel and simple platform for an efficient SERS detection was demonstrated in a hanging plasmonic droplet of Ag sols by virtue of three-dimensional (3D) SERS hotspots. The platform was a single droplet of concentrated Ag sols with analytes hung on a hydrophobically treated transparent cover glass. Liquid adhesive fo…
