Enhanced H2 sensing performance presented by Mg doped ZnO films fabricated with a novel ITO seed layerJournal of Materials Science: Materials in Electronics - Tập 26 - Trang 3458-3465 - 2015
K. Vijayalakshmi, A. Renitta
The present study investigates the influence of Mg doping on the H2 sensing properties of ZnO films fabricated with ITO seed layer by spray pyrolysis method. XRD results revealed that both undoped and Mg doped ZnO films were polycrystalline with a hexagonal wurtzite structure with highly oriented (002) plane perpendicular to the ITO substrate. The films were highly transparent in the visible range...... hiện toàn bộ
Preparation, structure and electrical properties of La1−xBaxCrO3 NTC ceramicsJournal of Materials Science: Materials in Electronics - Tập 28 - Trang 18873-18878 - 2017

The La1−xBaxCrO3 (x = 0–0.2) negative temperature coefficient (NTC) ceramics have been prepared by the traditional solid-state reaction method at 1600 °C. Scanning electron microscope images show that the doping of Ba2+ contributes to the increase in the density. X-ray diffraction analysis has revealed that the sintered ceramics crystallize in a single perovskite structure. X-ray photoelectron spe...... hiện toàn bộ

Low temperature sintering and microwave dielectric properties of BaO–0.6ZnO–2.9TiO2 ceramics using BaCu(B2O5) additionJournal of Materials Science: Materials in Electronics - Tập 26 - Trang 8819-8823 - 2015
Sen Peng, Jianming Xu, Hao Li, Tongcheng Huang, Shaojie Wang, Bing Xie, Gaofeng Luo, Jianhua Zhou
In this paper, the effect of BaCu(B2O5) addition on the sintering process, phase composition, microstructure and microwave dielectric properties of BaO–0.6ZnO–2.9TiO2 ceramics were investigated by the conventional solid-state reaction technique. It was suggested that the liquid phase of BaCu(B2O5) was responsible for the densification of the BaO–0.6ZnO–2.9TiO2 ceramics at approximate 900 °C. Using...... hiện toàn bộ
High capacity and excellent cyclic performances of Mn2O3/Mn3O4/C materials as li-ion battery anodeJournal of Materials Science: Materials in Electronics - Tập 35 - Trang 1-12 - 2023
Tianci Li, Yanchao Lan, Wenkai Yang, Jing Wang, Chunmei Wang, Shaowei Yao, Ying Wang
Due to the large volume change and poor conductivity, manganese oxide with high theoretical specific capacity is difficult to be widely used in the anode of lithium-ion battery. By the self-propagating sol–gel method, the nano-sized manganese oxide particles are embedded in the amorphous porous C in situ. Amorphous porous C and nano-manganese oxide particles can alleviate the volume effect of mang...... hiện toàn bộ
Chemical spray pyrolysis synthesis of covellite copper sulphide (CuS) thin films for economical counter electrode for DSSCsJournal of Materials Science: Materials in Electronics - Tập 29 - Trang 4940-4947 - 2017

Thin films of covellite copper sulphide (CuS) were deposited on FTO substrates using chemical spray pyrolysis technique. Influence of Cu-to-S molar ratio on structural, surface morphological, optical and electrical properties were systematically investigated using variety of characterization techniques. Formation of covellite CuS films was confirmed by low angle-XRD and Raman spectroscopy. The fie...... hiện toàn bộ
