Many narrow band-gap semiconductors cannot fulfil the energetic requirements for water splitting, thus the assistance of large external voltages to complete the water decomposition reaction is required. Through thermal decomposition of Fe(NO3)3 on n-Si nanowires prepared by the chemical etching method, we fabricated a high-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode that exhib...

Nanomaterials are used in practically every aspect of modern life, including agriculture. The aim of this study was to evaluate the effectiveness of iron oxide nanoparticles (Fe2O3 NPs) as a fertilizer to replace traditional Fe fertilizers, which have various shortcomings. The effects of the Fe2O3 NPs and a chelated-Fe fertilizer (ethylenediaminetetraacetic acid-Fe; EDTA-Fe) fertilizer on the g...

Hollow or porous hematite (α-Fe2O3) nanoarchitectures have emerged as promising crystals in the advanced materials research. In this contribution, hierarchical mesoporous α-Fe2O3 nanoarchitectures with a pod-like shape were synthesized via a room-temperature coprecipitation of FeCl3 and NaOH solutions, followed by a mild hydrothermal treatment (120°C to 210°C, 12.0 h). A formation mechanism bas...

Hierarchical 3D TiO2@Fe2O3 nanoframework arrays grown on a Ti substrate are synthesized via a facile hydrothermal reaction. As the synergetic effect of this hybrid material, the TiO2@Fe2O3 electrode shows superior rate capability and cycling performance to bare TiO2 and Fe2O3 electrodes.

A simple one-step NaCl-assisted microwave-solvothermal method has been developed for the preparation of monodisperse α-Fe2O3 mesoporous microspheres. In this approach, Fe(NO3)3 · 9H2O is used as the iron source, and polyvinylpyrrolidone (PVP) acts as a surfactant in the presence of NaCl in mixed solvents of H2O and ethanol. Under the present experimental conditions, monodisperse α-Fe2O3 mesopor...

The short lifetime of photogenerated charge carriers of hematite (α-Fe2O3) thin films strongly hindered the PEC performances. Herein, α-Fe2O3 thin films with surface nanowire were synthesized by electrodeposition and post annealing method for photoelectrocatalytic (PEC) water splitting. The thickness of the α-Fe2O3 films can be precisely controlled by adjusting the duration of the electrodeposi...

BACKGROUND Tau dysfunction is believed to be the primary cause of neurodegenerative disorders referred to as tauopathies, including Alzheimer's disease, Pick's disease, frontotemporal dementia and Parkinsonism. The role of microglial cells in the pathogenesis of tauopathies is still unclear. The activation of microglial cells has been correlated with neuroprotective effects through the release ...

Silane modified iron (III) oxide (SiFe2O3) nanoparticles reinforced chitosan (CS) nanocomposite membranes were prepared by solcast transformation method. The iron (III) oxide nanoparticles and nanocomposite membranes were investigated by UV (Visible) spectroscopy, FT-IR spectroscopy, XRD, SEM and TEM. The size and shape of iron (III) oxide and Si-Fe2O3 nanoparticles were determined by XRD and T...

A novel nanocomposite consisting of α-Fe2O3, Mn3O4 and reduced graphene oxide (r-GO) has been facilely synthesized through a two-step method: solvothermal reaction for Mn3O4-modified α-Fe2O3 (α-Fe2O3/Mn3O4) and self-assembly process for combining α-Fe2O3/Mn3O4 with r-GO (α-Fe2O3/Mn3O4/r-GO). The morphology and structure of the nanocomposite were characterized by X-ray diffraction (XRD), scannin...
