Traditional methods of characterizing the size, morphology, reactivity of nanomaterials often only provide static “snapshots” and require an iterative series of measurements for each condition. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to directly observe nucleation and growth, particle-particle interactions and more.

Electron beam induced growth of lead nanoparticles from a 40 mM aqueous solution of Pb(NO3)2. Nucleation was induced by the electron beam, and the particles grow via an Oswaldt ripening process followed by second growth stage in which the particles increase uniformly in size. The Oswaldt ripening process is indicated by the red circle. When these nanoparticles are in close proximity to larger nanoparticles, they decrease in size and ultimately disappear, while larger nanoparticles increase in size.

This real-time video shows two gold nanoparticles that are on the surface of larger iron oxide particles at 900° C. At this temperature the gold is very mobile, and the two particles coalesce into one larger nanoparticle. This demonstrates the stability of the Protochips Fusion system at high temperatures. This video was taken on a JEOL ARM200F (200 kV, Cs aberration correction) at JEOL in Akishima, Japan. For more information on Fusion, visit www.protochips.com/fusion
