    • From Zirconium Nanograins to Zirconia Nanoneedles 

      Zalnezhad, E.; Hamouda, A.M.S.; Jaworski, J.; Kim, Young Do ( Nature Publishing Group , 2016 , Article)
      Combinations of three simple techniques were utilized to gradually form zirconia nanoneedles from zirconium nanograins. First, a physical vapor deposition magnetron sputtering technique was used to deposit pure zirconium ...
