Abstract: The perovskite single-crystalline LaMnO3 nanocubes have been fabricated through a facile salt-assisted solution combustion process, using ethylene glycol as a fuel and corresponding nitrates as oxidants. The effects of the fuel-to-oxidant molar ratio and the fraction of added NaCl on the phase and microstructure of the products were investigated by X-ray diffraction, transmission electron microscopy and selected area electron diffraction. The possible mechanism about the effect of molten salt on morphological evolution of the as-prepared LaMnO3 particles in salt-assisted solution combustion synthesis was also discussed.

Abstract: Urchin-like CuO microspheres have been successfully synthesized via a simple water–ethyleneglycol (water–EG) mixed-solvothermal route at 100°C for 12h, employing cupric chloride (CuCl2) and potassium hydroxide (KOH) as starting reactants in the absence of any surfactant or template. The as-obtained product was characterized by means of powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and field-emission scanning electron microscopy (FESEM). It was found that the volume ratio of water and EG played an important role in the formation of urchin-like CuO microspheres. The UV–vis absorption and the photocatalytic degradation for organic dyes of the final product were also studied. [Copyright &y& Elsevier]

Abstract: The saturation magnetostriction of α″-Fe16N2 phase was evaluated by measuring the magnetostriction curve of Fe84.8N7.8B7.4 ribbon with α″-Fe16N2 nanocrystallites embedded in an amorphous matrix. The magnetostriction measurement was carried out at room temperature by means of the three terminal capacitance method. The prepared sample exhibits a saturation magnetostriction of 2.52×10−6. The saturation magnetostriction of α″-Fe16N2 phase is evaluated to be −19.1×10−6 according to a simple rule of mixtures. [Copyright &y& Elsevier]

Abstract: Dumbbell-shaped barium carbonate superstructures were successfully synthesized in the aqueous system containing egg albumin and ethylenediaminetetraacetate disodium (EDTA-2Na), employing BaCl2, NaHCO3 and NH3·H2O as the starting reagents. The as-prepared product was characterized by X-ray powder diffraction (XRD), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Some factors influencing the morphology of BaCO3 crystals, such as the time, the amounts of egg albumin and EDTA-2Na, were studied. Experimental facts showed that a proper amount of egg albumin and EDTA-2Na played crucial roles in the formation of dumbbell-shaped BaCO3 superstructures. [Copyright &y& Elsevier]

Abstract: In the present paper, we reported the successful synthesis of dumbbell-like YF3 nanostructures with a high yield in a mixed system of water/N,N-dimethylformamide (DMF) under the assistance of ultrasound waves of 40kHz with the ultrasonic power of 100% (200W) at 65°C for 2h, employing Y2O3 (99.99%) and NH4F as the starting reactants. The product was characterized by means of powder X-ray diffraction (XRD), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), selected area electron diffraction (SAED) pattern and field-emission scanning electron microscopy (SEM). Some factors influencing the morphology of YF3 nanostructures, including the ultrasonic time and power, the amount of NH4F, and the ratio of water/DMF, were systematically investigated. Research showed that the morphology of YF3 could be tuned by the volume ratio of water/DMF. The roles of DMF and the ultrasonic wave in the formation of YF3 nanostructures were discussed.

Highlights: [•] Pure monoclinic LaPO4 form was rapidly obtained by a simple oil-bath route at 120°C for 30min. [•] The integration of Eu3+ ions into LaPO4 matrix did not vary the phase of the final La1 − x Eu x PO4. [•] The shape and size of the La1 − x Eu x PO4 were markedly affected by the content of Eu3+ ions in LaPO4 host. [•] The as-prepared La1 − x Eu x PO4 microstructures exhibited good photoluminescence properties. [ABSTRACT FROM AUTHOR]

Abstract: CoSn(OH)6 nanocubes were rapidly prepared by a simple sonochemical route at room temperature for 30min, employing CoCl2, SnCl4 and NaOH as the starting reactants in the absence of any surfactant or template. Subsequently, CoSn(OH)6 nanocubes were converted into SnO2–Co3O4 hybrids by calcining at 500°C for 120min in air. Interestingly, the as-obtained SnO2–Co3O4 hybrids still kept the cubic morphology of CoSn(OH)6. The above samples were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and (high resolution) transmission electron microscopy (HRTEM/TEM). Experiments showed that SnO2–Co3O4 hybrids owned the stronger photocatalytic activity for the degradation of methylene blue than CoSn(OH)6 nanocubes. [Copyright &y& Elsevier]

Abstract: In this paper, LaPO4 nanorods have been successfully synthesized via a simple water–ethyleneglycol (H2O–EG) mixed-solvothermal route, employing lanthanum nitrate (La(NO3)3·xH2O) as a La3+ ion source and monobasic sodium phosphate (NaH2PO4·2H2O) as a ion source. The as-obtained products were characterized by means of X-ray powder diffraction (XRD), energy dispersive spectrometry (EDS), (high resolution) transmission electron microscopy (HR/TEM), selected area electron diffraction (SAED) and field emission scanning electron microscopy (FESEM). Some factors influencing the formation of LaPO4 nanorods, including the reaction temperature, the volume ratio of water/EG and the original amount of ions, were investigated. Experiments showed that the volume ratio of water/EG and the original amount of ions could markedly affect the morphology of the final product. [Copyright &y& Elsevier]

In this paper, large dendritic Bi nanostructures were synthesized viaa facile electrochemical deposition route at room temperature, employing Bi(NO3)3·5H2O as the reactant without assistance of any additive and protection of an inert atmosphere. The phase and morphology of the as-prepared product were characterized by means of powder X-ray diffraction (XRD), energy dispersive spectrometer (EDS), (high resolution) transmission electron microscopy (HR/TEM), selected area electron pattern (SAED) and scanning electron microscopy (SEM). Some factors influencing the formation of dendritic Bi nanostructures were investigated, including the depositing time, current, complexing agent, surfactant, the original amount and existing state of Bi(iii). Experiments showed that the existence state of Bi(iii) in the system, the depositing time and some complex agents could markedly affect the morphology of the final product. Also, the as-obtained product is found to have potential applications in the detection of trace metal such as Cd in water resource. [ABSTRACT FROM AUTHOR]
