  • Effect of doping on flux pinning of GdBa2Cu3O7-y 
    Zhang L; Xu X; Ding S; Zheng Minghui; Xiao Lin; Ren Hongtao; Jiao Yulei; Wang Xiu-Hong; Lin Zhi Wei (Jack); Zhu Jianguo (American Institute of Physics, 2005)
    Cylindrical single grains of GdBa2Cu3Oy (Gd-123) with a diameter of 25 mm were successfully fabricated by melt-texture growth (MTG) process in air to study the influence of different starting powders on flux pinning. ...
  • Structural and electronic properties of Fe3+ and Fe2+ centers in GaN from optical and EPR experiments 
    Malguth Enno; Hoffmann Axel; Gehlhoff W; Gelhausen Olaf; Phillips Matthew; Xu X (American Physical Society, 2006)
    This work provides a consistent picture of the structural, optical, and electronic properties of Fe-doped GaN. A set of high-quality GaN crystals doped with Fe at concentrations ranging from 5 X 1017 cm-3 to 2 X 1020 ...
  • Targeted destruction of murine macrophage cells with bioconjugated gold nanorods 
    Pissuwan Dakrong; Valenzuela Stella; Killingsworth Murray; Xu X; Cortie Michael (American Real Estate Society, 2005)
  • Third harmonics due to surface barrier in high-temperature superconductor 
    Xu X; Zhang L; Leng X; Ding S; Liu Hua Kun; Wang Xiu-Hong; Dou Shi; Lin Zhi Wei (Jack); Zhu Jianguo (American Institute of Physics, 2005)
    The influence of surface barrier on the third harmonics ac susceptibility sx3d is studied numerically. The surface barrier is described by a critical current density in surfaces which are higher than the inside one. The ...
