Protonic ceramic fuel cells (PCFCs) can use hydrogen and hydrocarbon fuels to generate electricity with good performance and anti-cooking resistance. Herein, a novel dual-phase perovskite oxide BaCe0.5Fe0.4Ni0.1O3-δ (BCFN) with BaCe0.5Fe0.5O3-δ (BCF) as one reference was synthesized, characterized and then evaluated as the symmetrical electrodes for PCFCs. Both BCF and BCFN can be self-assembled into an orthorhombic cerium-rich oxide phase and a cubic iron-rich oxide phase after calcined at 1000...

Ionic liquids are becoming widely applied in the extraction/separation of biological molecules. In this study, the solidification of ionic liquid 1-hydroxyethyl-3-vinylimidazole chloride ([HVIM]Cl) was achieved via one-pot free radical copolymerisation with divinylbenzene (DVB) as a cross-linking reagent, giving a mesoporous hydrophilic polymeric ionic liquid (PIL). Mesoporous PIL possesses a large surface area of 328.32 m2·g−1 and a high pore volume of 0.45 cm3·g−1. Owing to hydrophilic interac...

The effect of aging on a mechanical alloyed (MA) ferritic oxide dispersion strengthened (ODS) alloy was investigated focusing on the B2-NiAl nano-precipitates. The matrix of the alloy is decorated with a high volume fraction of B2-NiAl precipitates and dispersed nano-oxide particles. Due to the coarsening effect of Al on oxides and the changed Zener drag effect on grain growth, the bimodal grain structure was formed. With the extension of the aging time, the size of nano-precipitate increases an...

The work here deals with the observation of structural, optical and magnetic property of Eu2+ doped SnO2 nano particles. The structure is characterized by X-ray diffraction( XRD), transmission electron microscopy (TEM), Raman spectroscopy, UV–Vis absorption, photoluminescence (PL), and time resolved PL (TRPL) spectroscopy. The introduction of Eu affects the crystallite size and substitutes with Sn without showing any interstitial defect formation. With 1% doping as the limit for entering the cry...

We report upon synthesis of stable chains of magnetically aligned zero-valent α-Fe nanoparticles and investigation of their magnetization reversal mechanism. The magnetic hysteresis loops with magnetic field applied at various directions with respect to the nanoparticle chain are measured experimentally and reproduced numerically by precisely mimicking the sample geometry under finite element modeling. The magnetization reversal mechanism is visualized in all three dimensions (3Ds) using 3D simu...

In this study, TiO2 nanotube (TiO2NT) arrays were successfully synthesized via two-step anodization in organic electrolyte solutions composed of ethylene glycol, 0.5 wt% NH4F, and 3.0 wt% H2O. The effect of aged electrolytes on the morphological and photocatalytic properties of the obtained TiO2NTs was investigated. Field-emission scanning electron microscopy, X-ray diffractometry, UV–Vis absorption spectrometry, and photoluminescence measurements were also conducted to evaluate the physicochemi...

ZnO nanorod-based UV photosensing devices are synthesized using one-pot synthesis method, and their sensing properties are studied with the variation of nanorod growth area. With the variation of electrode position for the maximum growth area, the UV photosensing properties are thoroughly examined. Structural, morphological and optical properties are studied using XRD, FEG-SEM, FEG-TEM and UV–VIS spectroscopy. AC electrical conductivity, dielectric measurements and modulus spectroscopy at room t...

We synthesize a group of three-phase ferroelectric ceramics 0.35(Sr0.7Bi0.2) TiO3–0.65(Bi0.5Na0.5)TiO3–xSr(Mg1/3Nb2/3)O3 (BST–BNT–xSMN) using conventional solid-phase sintering method. When tunning the volume of SMN to 0.01, the ceramic sheet shows homogeneous microcrystal grains and highly dense crystal morphology, which favors a reductive dielectric permittivity (er) of 2250 and loss of 0.05. Under a high electric field of 100 kV cm−1, the BST–BNT-0.01SMN sample achieves a slender polarization...

In this work, the sulfur vacancies were successfully introduced into the ZnIn2S4 (ZIS) lattice through two facile approaches, plasma etching and annealing, for enhancing the photocatalytic performance. The optimized plasma-etched ZIS exhibited an enhanced H2 generation rate of 706 μmol g−1 h−1, which was 5 and 1.2 times higher than that of pure ZIS and annealed ZIS, respectively. Theoretical calculation demonstrated that surface S vacancy could arouse the catalytic activity of the adjacent S ato...
