    In this work, a simple method of ZnAl2O4-functionalization of ZnO microstructures is presented. The different characterization methods (structural, chemical, and micro-Raman) demonstrated the presence of only ZnO and ZnAl2O4 ...
  • LUPAN, Oleg; CHOW, Lee (Springer International Publishing Switzerland, 2013)
    Hydrogen has the potential to play an important role in energy and automobile industries in our society. Being an explosive gas, hydrogen is also a colorless and odorless gas; therefore, there is a great need to develop ...
