| 1 | Preparation and characterization of microcrack-free thick YBa_2Cu_3O_(7-δ) films显示文摘High quality epitaxial YBa2Cu3O7-δ (YBCO) superconducting films were fabricated on (00l) LaAlO3 substrates using the direct-current sputtering method. The attainment of an unusually high film thickness (up to 2.0 μm) without mi-crocracking was attributed in part to the presence of pores correlated with yttrium-rich composition in the films. The influ-ence of the film thickness on the microstructure was investigated by X-ray diffraction conventional scan (θ-2θ,ω-scan,pole figure) and high-resolution reciprocal space mapping. The films were c-axis oriented with no a-axis-oriented grains up to the thickness of 2 μm. The surface morphology and the critical current density (Jc) strongly depended on the film thickness. Furthermore,the reasons for these thickness dependences were elucidated in detail. | XIONG Jie QIN Wenfeng TANG Jinlong TAO Bowan CUI Xumei LI Yanrong | 2007 | Rare Metals2007，26，5： | 3 |
| 2 | Effects of precursor solution concentration on the properties and morphology of YBCO films deposited by TFA-MOD method显示文摘Epitaxial YBCO films were deposited on (100) LaAlO3 single-crystal substrates by metalorganic deposition ofmetal trifluoroacetate precursors with different concentrations. All the YBCO films have Tc around 91 K and Jc excess 2MA/cm2 at 77 K in zero field. XRD θ-2θscans show all the films have c-axis normal orientation. The FWHM (full width athalf-maximum intensity) values of X-ray ω-scans of (005) reflection are 0.379°, 0.283°, and 0.543° for the YBCO thin filmsdeposited with precursor solution concentrations of 1.52, 1.0, and 0.75 mol/L, respectively. With the concentration of theprecursors decreasing, the thickness of the films decreases linearly. SEM micrographs show that porosities in the films be-come bigger with the precursor solution concentration decreasing. The big porosities in the film with the lowest concentra-tion precursor deteriorate the superconducting property and make it have a wider superconducting transition and a lower Jc. | CUI Xumei TAO Bowan LI Yanrong LIU Xingzhao CHEN Jiajun XIONG Jie | 2005 | Rare Metals2005，24，3： | 2 |

| 5 | Preparation of Eco-Friendly High-Performance Manganese Dioxide Supercapacitors by Linear Sweep Voltammetry显示文摘In this paper,the non-polluting,non-toxic,and eco-friendly material-MnO_(2)electrodes were deposited on three-dimensional porous nickel(Ni)foam by linear sweep voltammetry,and the entire electrodeposition process did not require sintering of the material,which was fast and convenient while avoiding unnecessary energy consump-tion and thus was environmentally friendly.Scanning electron microscopy(SEM)and transmission electron microscopy were used to examine the surface and microscopic characteristics of each sample(TEM).Chronoam-perometry(CA),cyclic voltammetry(CV),galvanostatic charge/discharge(GCD),and electrochemical impedance spectroscopy(EIS)were then used to determine the electrochemical characteristics of the manufactured samples.The result suggests that the MnO_(2)-sv80 electrode sample at a scan rate of 80 mV/s^(−1)has excellent performance for the supercapacitor electrode.The specific capacitance was as high as 531.4 F g^(−1)at a current density of 1 A g^(−1)and remained at 223.2 F g^(−1)at an ultra-high current density of 20 A g^(−1),with capacitance retention of 42%. | Junshan Zhao Yihan Shi Ming Zhang Liu Zhang Xumei Cui Xinghua Zhu Jitong Su Dandan Jing Dingyu Yang | 2023 | Journal of Renewable Materials2023，11，1： | 0 |
