Polypropylene grafted maleic anhydride (PP-MA, 2500 g mole(-1)) has demonstrated its unique capability to synthesize 1-D ferromagnetic hard (292.7 Oe) γ-Fe2O3 nanochains made of ~24 nm nanoparticles vs. PP-MA with 8000 g mole(-1) for the synthesis of 1-D ferromagnetic soft (70.5 Oe) γ-Fe2O3 nanochains (30 nm) made of flowerlike nanoparticles.

A facile synthesis of Ag2S-hollow Fe2O3 nanocomposites with NIR photoluminescence was firstly demonstrated by the sulfidation of Ag-Fe2O3 core-shell nanoparticles. Characteristic morphology transformations along with color changes were recorded and a mechanism was proposed for the sulfidation process, which can provide new possibilities to fabricate other complex nanostructures.

TiO2 is an exemplary semiconductor anode material for photoelectrochemical (PEC) water-splitting electrodes due to its functionality, long-term stability in corrosive environments, nontoxicity, and low cost. In this study, TiO2 photoanodes with enhanced photocurrent density were synthesized by atomic layer deposition (ALD) of TiO2 onto a porous, transparent, and conductive fluorine-doped tin ox...

T The nanostructures of Fe2O3 have been synthesized applying sour cherry juice and iron chloride as a low-cost and eco-friendly method at ambient conditions. Sour cherry juice has been used as a surfactant and the kind of surfactant had an important effect on the size and morphology of the products. The effect of sour cherry juice concentration and calcination temperature...

Novel flexible, mesoporous, and magnetic γ-Fe2O3@SiO2 nanofibrous membranes with high γ-Fe2O3 content and uniform distribution were prepared by a facile in situ growth method, which exhibit prominent mechanical strength and magnetic responsive performance, as well as efficient adsorption for organics in water.

Siderophile elements are depleted in the Earth's mantle, relative to chondritic meteorites, as a result of equilibration with core-forming Fe-rich metal. Measurements of metal-silicate partition coefficients show that mantle depletions of slightly siderophile elements (e.g. Cr, V) must have occurred at more reducing conditions than those inferred from the current mantle FeO content. This implie...

in this work firstly fe2o3 nanoparticles were synthesized via a simple chemical method. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform infrared (ft-ir) spectroscopy. vibrating sample magnetometer (vsm) shows nanoparticles exhibit ferromagnetic behavior. to continue some of the 2-naphthol condensed 1,3-oxazinon...

A dye-sensitized photocatalytic (DSP) approach is considered as one of the promising approaches for developing visible light- and near-infrared light-responsive photocatalysts. DSP systems are still affected by significant drawbacks, such low light absorption efficiency. Recently, it has been demonstrated that plasmonic metal nanostructures can be used to enhance efficiency overall dye-sensitiz...
