4D electron microscopy reveals nano eutectic reactions

23 Nov 2017 Lok Yi Lee 
Schematic of the set-up of the transmission electron microscope. A picosecond pump laser initiates the eutectic reaction in the sample. After a certain time delay, a nanosecond ultraviolet laser pulse generates an electron pulse, which is used to image the sample.
Researchers at Caltech are the first to image the distinct stages of a eutectic transformation, wh
