00:00 The question, and a story to go with it
00:11 The quick technical answer: yes, from many precursors
00:19 Flame and plasma are both good candidates for a reactive synthesis environment
00:31 Oxidize, atomize, condense onto surfaces to grow nanomaterials
00:59 The nano boom era: every proposal we wrote had "nano" in the title
01:06 The chemists laughed because they were working in Angstroms (sub-nanometer)
01:18 So yes, plasma can make nanoparticles
01:23 The real answer depends on which particle, what purity, what reproducibility
01:30 The story starts ...
