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 rapid heating and quenching of micron-sized copper-silver particles in the SEM. The video demonstrates how quickly the Protochips Fusion™ can heat and quench samples, on the order of milliseconds. Take note of the temperature display on the upper left corner of the video.

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

This workflow explains the procedure for preparing FIB samples onto a MEMS-based E-chip for in situ TEM. FIB sample preparation can be used to prepare a wide variety of materials for TEM or in situ TEM analysis and is a relatively simple technique to learn.
