2. Girshick (cont.) Progress
• Synthesized Al particles over range of conditions from AlCl3 feed system in plasma torch apparatus
Determined effects of reactant feed rates and of counterflow on particle-size distributions with scanning mobility particle sizer
Characterized particles off-line by
transmission electron midroscopy
energy dispersive X-ray spectroscopy
In progress:
thin oxide growth on Al nanoparticles
passivation with polymer films
