We report synthesis of α-Fe2O3 (hematite) nanorods by reverse micelles method using cetyltrimethyl ammonium bromide (CTAB) as surfactant and calcined at 300 °C. The calcined α-Fe2O3 nanorods were characterized by X-ray diffraction (XRD), high-resolution scanning electron microscopy (HRSEM), transmission electron microscopy (TEM), energy dispersive spectrometer (EDS), fourier transform infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). The result showed that the α-Fe2O3 nanorods were hexagonal structure. The nanorods have diameter of 30-50 nm and length of 120-150 nm. The weak ferromagnetic behavior was observed with saturation magnetization = 0.6 emu/g, coercive force = 25 Oe and remanant magnetization = 0.03 emu/g. (© 2010 WILEY-VCH Verlag GmbH & Co.

Interparticle double charge transfer mechanism of heterojunction α-Fe 2 O 3 /Cu 2 O mixed oxide catalysts and its visible light photocatalytic activity
TL;DR: In this article, a double charge transfer mechanism was proposed for the separation and transfer of photogenerated charge carriers in the photocatalysts, which is mainly attributed to the enhanced visible light absorption, efficient charge carriers separation, and the loading of α-Fe2O3 on Cu2O.

Control of Thickness and Orientation of Solution-Grown Silicon Nanowires
TL;DR: Bulk quantities of defect-free silicon nanowires with nearly uniform diameters were grown to a length of several micrometers with a supercritical fluid solution-phase approach, and visible photoluminescence due to quantum confinement effects was observed, as were discrete optical transitions in the ultraviolet-visible absorbance spectra.
