Top-down approach using supercritical carbon dioxide ball. May 11, 2020 Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi sub 2 /sub Te sub 3 /sub grains 0000-0001-5310-360X Atwa Mohamed Mr email protected Nakagawa Tessui Professor Dr Yonamine Akira Mr Lloyd David Dr Schreiber Makoto Mr Miyazaki Koji Professor Takeuchi Tsunehiro Professor Feb 24, 2020 In this chapter, we present an overview of synthesis of MgO nanoparticles and thin films by using top-down and bottom-up approaches. The bottom-up approaches are generally utilized to grow nanoparticles by the methods that involve chemical reactions. Sometimes, methods based on these reactions are also able to grow thin films. The top-down approaches are preferred for growing thin
