Characterizing material systems often requires numerous tools that must be used independently to understand the underlying science. With in situ electron microscopy, you can often use your microscope to simultaneously study the structure, processing, properties, and performance of material systems in real-time.

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.

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.
