    Ensuring global food security and environmental sustainability is dependent upon the contribution of the world’s hundred million smallholder farms, but the contributions of smallholder farms to global agricultural greenhouse ...
  • Systematic research on the effect of both positive and negative mismatch dopants in double-doped YBCO superconducting films 
    Xu, Yan; Suo, Hongli; Qureishy, Thomas; Grivel, Jean-Claude; Mikheenko, Pavlo; Liu, Min; Ma, Lin; Zhang, Xiaolong; Zhou, Yuqi; Liu, Jianhua; Wang, Lei; Zhang, Zili; Wang, Qiuliang (Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)
    We report a novel doping strategy for YBa2Cu3O7-x (YBCO) superconducting films by using a positive mismatch, Ba2YNbO6 (BYNO), and a negative mismatch, LaAlO3 (LAO), simultaneously. Double doping can significantly reduce ...
