We report the structure and stability of ceria units deposited on the surface of γ-Al2O3 or incorporated in its cavities, as determined by periodic density functional calculations. Ceria species are modeled as CeO2 or Ce2O4 moieties or as a small nanoparticle, Ce13O26, on the (100) and (001) surfaces of a γ-Al2O3 slab…
A complete quenching of photoluminescence (PL) of PS, on chemical modifications including Ag nanoparticle deposition and thermal annealing, was achieved.
A layer-by-layer growth through alternating chemisorption of isocyanate functional star-shaped polyethers (NCO-sP(EO-stat-PO)) and a linear polymer ((PVFA-co-PVAm)) is described.
Five one-dimensional heterobimetallic chains based on the new dicyanoruthenium( iii ) complex, trans -(Ph 4 P)[Ru(L) 2 (CN) 2 ] (L = 2′-hydroxyacetophenone imine), are synthesized and structurally characterized. Magnetostructural correlation for these compounds is discussed.
Effects of silver nanoparticle (AgNP) and gold nanoparticle (AuNP) on photon upconversion based on sensitized triplet-triplet annihilation were examined in the system of platinum(II) octaethylporphyrin (PtOEP) and 9,10-diphenylanthracene (DPA). The ITO electrodes immobilized with AgNPs and AuNPs were prepared by elect…
For stacked metamaterials, meta-atoms act as real atoms in nature materials, whose characteristic frequency bands behave as the equivalent energy levels.
The rare earth porphyrins represent a promising class of materials, due to their physical-chemical properties. A detailed study of the local structure of the RE series of porphyrins RETPP (RE = Yb, Er) was carried out by X-ray absorption spectroscopy (XAFS) using the synchrotron radiation. XAFS experiments prove the t…
In this work, a new structure of CdS/CdTe based solar cell is proposed, where two of the fundamental drawbacks of traditional CdS/CdTe are addressed. The relatively low bandgap of CdS window layer, along with a significant lattice mismatch between CdS and CdTe lower the efficiency of conventional CdS/CdTe solar cell.…
Whilst polystyrene microgels belong to the oldest family of microgel particles, their behaviours when deposited onto substrates or prepared as composites have received little attention. Because polystyrene microgels are solvent-swellable, and inherently colloidally stable, they are well suited to form composites with…
We have performed (63)Cu, (65)Cu, and (137)Ba NMR on Ba8Cu5SixGe41-x, a series of intermetallic clathrates known for their potential as thermoelectric materials, in order to investigate the electronic behavior of the samples. The spectra and spin-lattice relaxation times were measured at 77 K and 290 K for the entire…

By varying only one chemical bond of the building blocks, the CMPs P-TPATCz and P-CzPTCz showed a sharp difference.
A side-chain polymer based on discotic 1,3,4-oxadiazole displays liquid crystalline properties at the room temperature region, and exhibits photoluminescent behaviors in solution, the solid state and liquid crystalline mesophase.
A thorough theoretical analysis was carried out on the sulfoxidation with H2O2 catalyzed by a tetranuclear peroxotungstate [SiO4{WO(O2)2}4](4-). The active species is the [SiO4{WO(O2)2}4(H2O2)](4-) (SiW4(H2O2)) complex rather than [SiO4{WO(O2)2}4](4-) (SiW4). The catalytic cycle consists of three elementary processes:…
Supramolecular complex formed from a carbazolylphenyl-porphyrin first generation dendrimer and [2,2,2]cryptand was prepared and investigated the influence of alkali metal cations on its formation and properties.
Calixpyrrole-armed metal phthalocyanine undergoes complexation by anions at the apical metal position upon light excitation.
The injection of water during melt blending modified the localization of clay in immiscible polymer blends from one phase to the other and improved their dispersion state.
Carbonaceous deposits can reduce the durability and performance of diesel engines. Chemical cleaning methods are widely used to remove the deposits in remanufacturing industry but the wasted liquid is harmful to the environment. In this paper the supercritical CO2 cleaning technology, an environmentally friendly appro…
We have developed a hot electron induced photocurrent enhancement system of strongly coupled Ag@perylene core–shell nanowires.
A low melting point bismuthate glass was developed for bonding SiC p /Al composite, and the novel SiC p /Al composite–glass material was prepared.
