Understanding the nanoscale processes that control corrosion initiation and propagation in bulk materials is a critical area of research. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to study the underlying mechanisms control corrosion initiation and propagation.

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
The Poseidon platform enables observation of dynamic processes in situ. This movie shows the formation of salt crystals from a saturated solution of phosphate buffered saline. Images were acquired at a rate of 1 frame per second and are shown at 5 times real speed. 500 nm liquid thickness. Images collected using a Philips/FEI CM300FEG TEM at 300 kV.
