Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy spectroscopy (RAS) during growth. It is demonstrated that the morphology of the array can be tai…
Surface-enhanced resonance Raman scattering (SERRS) spectroscopy is a highly sensitive optical technique capable of detecting multiple analytes rapidly and simultaneously. There is significant interest in SERRS detection in micro- and nanotechnologies, as it can be used to detect extremely low analyte concentrations i…
This paper reports the in vitro degradation of three-dimensional, highly porous tissue engineering scaffolds and non-porous thin films based on poly (L-lactide) (PLLA) biopolymers. The tissue engineering scaffolds were produced through the emulsion freezing/freeze-drying technique. The nonporous thin films were produc…
We aim to study magnetic and thermal behaviors of some melamine cored macromolecular Schiff base complexes. In this context, tripodal ligands were synthesized by reacting melamine with 4-carboxybenzaldehyde or 4-hydroxybenzaldehyde. Then, 16 new trinuclear Fe(III), Cr(III), Mn(III), and Al(III) complexes were synthesi…
Abstract Graphene has great potential in electrochemical storage applications for supercapacitors owing to its high conductivity, large surface area, and the economical feasibility in producing it. The main issue that faces graphene nanomaterials in this application is that they tend to restack, thus decreasing the ac…
Correction for 'Super-large dendrites composed of trigonal PbO2 nanoplates with enhanced performances for electrochemical devices' by Liang-Xin Ding et al., Chem. Commun., 2012, 1275-1277, DOI: 10.1039/C2CC15271A.
Antibacterial nanocrystals have attracted great interests in recent years. In fact, with the emergence and increase of microbial organisms resistant to multiple antibiotics, many researchers have tried to develop new antibiotics. The aim of this research is to compare antibacterial activity of mono-metallic with compo…
Temperature dependent phase transitions of compounds (GeTe)(n)Sb(2)Te(3) (n = 6, 12, 15) have been investigated by in situ microfocus Laue diffraction. Diffusion processes involving cation defect ordering at ~300 °C lead to different nanostructures which are correlated to changes of the thermoelectric characteristics.
A chemically enhanced mechanism of surface-enhanced Raman scattering (SERS) was investigated using a series of metal-charge-transfer (CT) complex systems fabricated by a self-assembly method. The developed Ag/4-mercaptophenols (MPH)/ n -TiO 2 system presented layer number-dependent SERS spectra. By using the electron…
The influence of nanocatalyst on three main reactions for natural gas conversion such as steam reforming, dry reforming and oxidative coupling of methane has been reviewed with an emphasis on the literatures’ reports and results. Although literatures’ experimental results showed that the conversion of methane over the…
Abstract In this article, a novel eggshell/β‐PP bio‐composite was prepared and evaluated. First the waste chicken eggshell (ES) was modified by a stingy amount of pimelic acid (PA) through solution method, and then compounded with PP through melt blending method. The crystalline form, mechanical properties, and morpho…
To optimize the performance of electric double-layer capacitors (EDLCs) with ionic liquids (ILs) based on LiTFSI and 2-oxazolidinone as electrolyte, we simulated possible IL structures and ion sizes, and IL compatibility with three kinds of carbon materials was investigated. Mesoporous activated carbon (MEAC) with a s…
OBJECTIVES: PEGylated liposomes could evade recognition by the reticulo-endothelial system and prolong the circulation time of vesicles, resulting in enhanced targeting efficiency and antitumour effect. Typically, vesicles are modified with distearoylphosphatidylethanolamine (DSPE)-polyethylene glycol (PEG) at a high…
A systematic approach for increasing the accuracy of the reference interaction site model (RISM) theory is introduced that uses input from simulation results to produce very accurate site-site pair correlation functions for single component molecular liquids. The methodology allows the computation of the "RISM bridge…
In situ cation exchange between alkali ions in ternary alkali lanthanide (Ln3+) fluoride on the nanoscale is reported. Experimental results reveal that the differences in the solubility constants and thermodynamic stability of the reactants and products affect the irreversible cation exchange between potassium and sod…
Abstract Different laser dyes (with special interest in boron dipyrromethene) are incorporated as guests into the channels of zeolite L. The resulting doped material is fully characterized by steady‐state and time‐resolved photophysical techniques. The pores of zeolite L are filled with high amounts of dyes, which are…
The compound Ba(8)Hg(3)U(3)S(18) was obtained from the solid-state reaction at 1123 K of U, HgS, BaS, and S, with BaBr(2)/KBr or BaCl(2) as a flux. This material crystallizes in a new structure type in space group P6 of the hexagonal system with three formula units in a cell of dimensions a = 27.08(1) Å, c = 4.208(2)…
Two series of o-diamidobenzenes, bearing long-chain alkyl substituted gallic ester groups, have been synthesised. The 3,4,5,6-unsubstituted amides 7 with a minimum chain length of C9 exhibited columnar rectangular mesophases of p2mm symmetry with Z = 2. The liquid crystalline phases spread over phase width of extremel…
We have studied the mechanism of the water–gas shift reaction (WGS, CO + H 2 O → CO 2 + H 2 ) catalyzed by nanosized gold particles by using density functional theory calculations. The molecular structures and adsorbate/substrate interaction energies of H 2 O/Au 38, CO/Au 38, HO/Au 38, and H/Au 38 configurations were…
New inorganic hybrid nanoparticles integrating different materials in a core/shell structure of iron and bismuth oxides have been synthesized by a simple aqueous route. The method is based on the precipitation of an Fe(II) salt in the presence of bismuth(III) cations in a mild oxidant and leads to highly uniform and c…
