Abstract null null My comments concern the significant error in the crystallographic part of the commented paper. It was discovered that the studied crystals are of sillenite type and the correct formula should be Bi25FeO39:Ni,Ti instead of BiFeO3. Moreover, the type of unit cell is not correct. Due to the doping the new type of unit cell, previously unknown, was proposed for such crystals. It was found that the studied sample contains two slightly different phases of the sillenite type. The act...

Abstract null null High-performance Fe3S4@reduced graphene oxide (rGO) as a novel anode material for alkaline rechargeable battery is successfully achieved via a facile hydrothermal method. The structural and electrochemical properties of the Fe3S4@rGO composites are evaluated systematically. It is interestingly found that increasing GO content effectively decreases the particle size of Fe3S4 in the composites. As expected, the Fe3S4@rGO composite with 10% rGO shows better high-rate capability a...

Abstract null null For the first time, A2BO4 type high-entropy oxide is applied to SOFC cathode. In this paper, a (La0.2Pr0.2Nd0.2Sm0.2Gd0.2)2CuO4 high-entropy oxide (HE-LCO) is synthesized. The phase structure, DC conductivity, high-temperature thermal expansion and electrochemical performance of HE-LCO are studied in detail. HE-LCO crystallizes in tetragonal symmetry with space group I4/mmm. The thermal expansion coefficient of HE-LCO is 12.19 × 10−6 K−1 in the range of 100–800 °C, which is co...
Abstract null null Vanadium-based materials with high capacity and stability are needed to promote aqueous zinc ion batteries in large-scale energy storage. NH3 modified β-Na0.33V2O5 is prepared by a facile hydrothermal method and subsequent calcination. The NH3 modification mechanism of β-Na0.33V2O5 is proposed, which includes forming vacancies, structural defects and V-O-N bonds after escaping most ammonia molecules from β-Na0.33V2O5’s framework, and retaining a small part of ammonia molecules...

Abstract null null Transition metal fluorides have attracted widespread interest in recent years on account of their high energy density. However, their low conductivity and poor cyclability limit their development in next-generation power batteries. Herein, two methods (vapor-solid method and traditional calcination fluorination method) were used to successfully synthesize the manganese fluoride nanoparticle anode material attached on in-situ multi-vacancy carbon. Experimental data shows that v...

Abstract null null Flexible force-sensitive sensors are widely used in wearable devices, electronic skins, human-computer interaction and other fields due to their simple manufacturing process, low cost, strong flexibility and great integration potential. A new type of FeSiBY amorphous alloy flexible force-sensitive film and its sensor has been developed in this paper. The film had high elastic modulus, microhardness and higher phase transition temperature. The piezomagnetic effect of this new t...

Abstract null null Li2ZrO3, K-doped Li2ZrO3, and mixed Li2ZrO3-Na2ZrO3 based sorbents were synthesized through wet impregnation of alkaline solutions in a suspension of zirconia nanoparticles. Structural Raman and surface XPS characterizations were performed and the zirconate reactivity was analyzed through operando Raman experiments. t-Li2ZrO3, m-Na2ZrO3, m-ZrO2, m-Li2CO3 and m-Na2CO3 phases were detected by Raman spectroscopy and XRD. Sorption tests were performed at 500 °C with low and high C...

Abstract null null Transition metal oxides as the electrode material of supercapacitors have been widely studied due to their high energy density. However, relatively low power density resulting from poor conductivity of the metal oxides limits their application. In this paper, a new N-doped NiCoO2 nanosheet array on Ni foam was synthesized through an ammonia-induced reduction strategy. During the ventilation of NH3 in the ammonia annealing stage, N was doped into the structure of NiCoO2, which ...

Abstract null null In this study, a rGH/α-Ag3VO4/GOQDs composite photocatalyst with a three-dimensional network space structure is designed, to attain high photocatalytic efficiency and adsorption synergy. The synthesized composite is supported by graphene hydrogel which has a surface adsorption effect on the composite materials to achieve high adsorption capacity and rapid adsorption of pollutants. GOQDs promote α-Ag3VO4 photogenerated electron-hole separation and enhance the interface stabilit...

Abstract null null In this study, nanoparticles of ZnFe2O4 were prepared at low temperatures by the coprecipitation method and for the first time using non-standard Moroccan reagents. The formation of Zinc Ferrite was confirmed by structural characterization techniques XRD and FTIR. From XRD data, the pure ZnFe2O4 phase was obtained at low temperatures (400 and 500 °C), with a cubic spinel structure (space group Fd3m). In addition, from Rietveld analysis the coordinates of the atomic positions o...
