      Zhou, Wuzong; Yu, Fengjiao; Greer, Heather Frances; Jiang, Zheng; Edwards, Peter P. (2012-09) - Journal article
      Scanning electron microscopy and high-resolution transmission electron microscopy have been used to investigate non-classic crystal growth of catalytic nanoparticles, such as zeolites, perovskites, metal and alloy particles. ...
    • Enhanced photoluminescence emission and thermal stability from introduced cation disorder in phosphors 

      Lin, Chun Che; Tsai, Yi‒Ting; Johnston, Hannah; Fang, Mu‒Huai; Yu, Fengjiao; Zhou, Wuzong; Whitfield, Pamela; Li, Ye; Wang, Jing; Liu, Ru‒Shi; Attfield, J. Paul (2017-08-30) - Journal article
      Optimising properties of phosphors for use in white light‒emitting diodes (WLEDs) is an important materials challenge. Most phosphors have a low level of lattice disorder due to mismatch between the host and activator ...
    • Metal-organic framework-derived hybrid carbon nanocages as bifunctional electrocatalyst for oxygen reduction and evolution 

      Liu, Shaohong; Wang, Zhiyu; Zhou, Si; Yu, Fengjiao; Yu, Mengzhou; Chiang, Chang-Yang; Zhou, Wuzong; Zhao, Jijun; Qiu, Jieshan (2017-08-18) - Journal article
      Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is cornerstone reactions of many renewable energy technologies. Developing cheap yet durable substitutes of precious metal catalysts, especially the ...
    • Multivalent cation crosslinking suppresses highly energetic graphene oxide’s flammability 

      Turgut, Hulusi; Tian, Z. Ryan; Yu, Fengjiao; Zhou, Wuzong (2017-03-16) - Journal article
      Graphene oxide (GO), a common intermediate for making graphene-like materials from graphite, was recently found to possess an explosive fire-hazard that can jeopardize the GO’s large-scale production and wide applications. ...
    • NIR-assisted orchid virus therapy using urchin bimetallic nanomaterials in phalaenopsis 

      Chen, Shin-Yu; Cheng, Liang-Chien; Chen, Chien-Wei; Lee, Po-Han; Yu, Fengjiao; Zhou, Wuzong; Liu, Ru-Shi; Do, Yi-Yin; Huang, Pung-Ling (2013-08-14) - Journal article
      The use of nanoparticles has drawn special attention, particularly in the treatment of plant diseases. Cymbidium mosaic virus (CymMV) and Odontoglossum ring spot virus (ORSV) are the most prevalent and serious diseases ...
    • Relaxor-to-ferroelectric crossover and disruption of polar order in "empty" tetragonal tungsten bronzes 

      Gardner, Jonathan; Yu, Fengjiao; Tang, Chiu; Kockelmann, Winfried; Zhou, Wuzong; Morrison, Finlay D. (2016-07-12) - Journal article
      Combined temperature-dependent structural and electrical characterization of a series of “empty” ferroelectric tetragonal tungsten bronzes (TTBs) of composition Ba4(La1- xNdx)0.67□1.33Nb10O30 are reported. The La-material ...
