0.1016/j.nanoen.2 lsevier Ltd. All rig thors. Tel.: +86 2 : zhanhu.guo@lam Abstract To increase the energy density of supercapacitors to approach that of batteries, the current research is always directed towards the cathode materials, whereas the anode materials are rarely studied. In the present work, single-crystalline Fe2O3 nanoparticles directly grown on graphene hydrogels are investigated...

As the demands for nanotechnology and nanoparticle (NP) applications in agriculture increase, the ecological risk has drawn more attention because of the unpredictable results of interactions between NPs and transgenic crops. In this study, we investigated the effects of various concentrations of Fe2O3 NPs on Bt-transgenic cotton in comparison with conventional cotton for 10 days. Each treatmen...

In this study, the effects of Fe2O3 (addition, 2, 5, 10, and 50 wt %) on the microstructure, mechanical properties, corrosion behaviors, and in vitro biocompatibility of Fe-Fe2O3 composites fabricated by spark plasma sintering were systematically investigated as a novel-structure biodegradable metallic material. The results of X-ray diffraction analysis and optical microscopy indicated that Fe-...

10 Influence of phase composition, structural peculiarities and grain size of Fe2O3–SnO2 nanocomposites prepared by sol–gel technology on gas-sensitive properties of the corresponding gas sensors has been studied in the paper. The characteristics of thin film sensors were obtained with regards to NO2 and C2H5OH. Behaviour of thick film sensors was estimated in humid C2H5OH ambient. High sensiti...

This study was performed to assess the growth promoting potential of dietary Fe2O3 NPs in Macrobrachium rosenbergii PL. Fe2O3 NPs was supplemented at 0, 10, 20, 30, 40 and 50 mg kg-1 with the basal diet (containing 5.45 mg Iron kg-1). The concentration of Fe in Fe2O3 NPs supplemented diet was increased correspondingly. Fe2O3 NPs supplemented diets were fed to M. rosenbergii PL (initial weight, ...

One major obstacle for successful application of nanoparticles in medicine is its potential nanotoxicity on the environment and human health. In this study, we evaluated the cytotoxicity effect of dimercaptosuccinic acid-coated iron oxide (DMSA-Fe2O3) using cultured human aortic endothelial cells (HAECs). Our results showed that DMSA-Fe2O3 in the culture medium could be absorbed into HAECs, and...

Coupling ultrasmall Fe2O3 particles (~4.0 nm) with the MoS2 nanosheets is achieved by a facile method for high-performance anode material for Li-ion battery. MoS2 nanosheets in the composite can serve as scaffolds, efficiently buffering the large volume change of Fe2O3 during charge/discharge process, whereas the ultrasmall Fe2O3 nanoparticles mainly provide the specific capacity. Due to bigger...
