Synthesis and characterization of in situ Fe2O3-coated FeF3 cathode materials for rechargeable lithium batteries

21-Nov-2012 | Wei Zhang; Lin Ma; Hongjun Yue; Yong Yang, Journal of Materials Chemistry, 2012

Here, a novel architecture of a core–shell structured FeF3@Fe2O3 composite with particle size of 100–150 nm and tunable Fe2O3 content is synthesized by a simple heat treatment process utilizing FeF3 with fine network structure as precursor. The structure, morphology and electrochemical ...


Platinum–Cobalt alloy networks for methanol oxidation electrocatalysis

31-Oct-2012 | Jiangfeng Xu; Xinyu Liu; Yu Chen; Yiming Zhou; Tianhong Lu; Yawen Tang, Journal of Materials Chemistry, 2012

Three-dimensional (3D) platinum–cobalt alloy networks nanostructures with a high alloying degree were synthesized through a room temperature wet-chemical synthetic method using the K2PtCl4/K3Co(CN)6 cyanogel as reaction precursor in the absence of surfactants and templates. The size, morphology ...


The effect of mineral coating morphology on mesenchymal stem cell attachment and expansion

25-Oct-2012 | Siyoung Choi; William L Murphy, Journal of Materials Chemistry, 2012

Previous studies have demonstrated the influence of calcium phosphate (CaP) mineral coating characteristics on cell attachment, proliferation, and differentiation. However, the wide range of mineral properties that can potentially influence cell behavior calls for an efficient platform to screen ...


Microstructured electrodeposited polypyrrole-phthalocyanine hybrid material, from morphology to ammonia sensing

17-Oct-2012 | Thibaut Sizun; Tilia Patois; Marcel Bouvet; Boris Lakard, Journal of Materials Chemistry, 2012

Hybrid materials combining polypyrrole with ionic macrocycles as counterions are electrosynthesized at the surface of platinum interdigited electrodes. The chemical composition of the hybrid films are characterized by infrared reflexion absorption spectroscopy (IRRAS) and glow discharge optical ...


Enhanced sintering characteristics and microwave dielectric properties of Li2TiO3 due to nano-size and nonstoichiometry effect

17-Oct-2012 | Yi-zhou Hao; Qi-long Zhang; Jian Zhang; Cheng-rong Xin; Hui Yang, Journal of Materials Chemistry, 2012

Ultrafine Li2TiO3 nanopowder was synthesized by a sol–gel method. The effect of a slight A- and B-site cation nonstoichiometry on the structure, densification and microwave dielectric properties of Li2TiO3 was investigated. The phase presence and surface morphology were determined by XRD and SEM ...


A facile and effective method to prepare long-persistent phophorescent nanospheres and its potential application for in vivo imaging

10-Oct-2012 | Zhan-Jun Li; Hong-Wu Zhang; Meng Sun; Jiang-Shan Shen; Haixia Fu, Journal of Materials Chemistry, 2012

In order to prepare new promising optical nanoprobes, monodisperse long afterglow nanospheres were successfully synthesized using mesoporous silica nanospheres both as morphology-controlling templates and silicon source of long afterglow silicate. In our experiments, metal ions (Sr2+, Mg2+, Eu3+, ...


Monodispersed ultrathin GdF3 nanowires: oriented attachment, luminescence, and relaxivity for MRI contrast agents

03-Oct-2012 | Yang Tian; Hong-Yu Yang; Kai Li; Xue Jin, Journal of Materials Chemistry, 2012

A facile solvothermal approach was used to synthesize monodispersed ultrathin GdF3 nanowires via an oriented attachment mechanism. Gadolinium nitrate acted as the Gd source, n-octylamine and oleic acid as capping ligands, and n-octanol as solvent. The phase and morphology of the nanowires were ...


Solution combustion synthesis, photoluminescence and X-ray luminescence of Eu-doped nanoceria CeO2:Eu

26-Sep-2012 | Shikao Shi; Marius Hossu; Ryan Hall; Wei Chen, Journal of Materials Chemistry, 2012

Rare earth Eu3+ -doped nanoceria with an average size range 60 nm were synthesized by urea-nitrate solution combustion reaction. The microstructure and morphology of the samples were characterized by X-ray diffraction patterns (XRD), X-ray photoelectron spectroscopy (XPS), and field emission ...


Adverse effects of graphene incorporated in TiO2 photocatalyst on minuscule animals under solar light irradiation

26-Sep-2012 | O Akhavan; E. Ghaderi; Kourosh Rahimi, Journal of Materials Chemistry, 2012

The adverse effect of graphene-titanium oxide composite films (containing sheet-like surface morphology) on Caenorhabditis elegans nematodes (as a model for minuscule animals) was investigated in a solar light-induced photocatalytic process. X-ray photoelectron spectroscopy demonstrated ...


High-rate Capacitive Performance of Graphene Aerogel with a Superhigh C/O Molar Ratio

25-Sep-2012 | Xiaozhong Wu; Jin Zhou; Wei Xing; Guiqiang Wang; Hongyou Cui; Shuping Zhuo; Qingzhong Xue; Zi-Feng Yan; Shizhang Qiao, Journal of Materials Chemistry, 2012

Graphene aerogel (GA) is successfully prepared through hydrogen reduction of graphene oxide aerogel (GOA) which is self-assembled from graphene oxide solution and subsequently dried by a supercritical CO2 method. The morphology, structure and surface property evolution in the preparation of GA ...
