DESCRIPTION: Metallic nanoparticles are utilized in a growing number of app
 lications due to their unique and tunable properties. However\, one of the
  primary tools used to tune bulk metals properties\, recrystallization\, i
 s yet to be used in the case of nanoparticles. We studied pristine\, singl
 e crystal platinum nanoparticles during a recrystallization annealing afte
 r deformation. We found that deformation causes a dramatic change in parti
 cles orientation\, while annealing induced a plethora of different particl
 e behaviors. Microstructurally\, nucleation of new grains was observed\, b
 ut in the smallest particles these new grains were quickly absorbed back i
 nto the deformed matrix. We describe a phenomenological kinetic model to e
 xplain the strong correlation between the particle properties and their an
 nealing behavior.\nSpeaker: Dr. Jonathan Zimmerman
