Image Contest Winners Announced

Congratulations to the winners of our latest image contest! Thank you to all who submitted. 

1st Place

Rigel Hanbury, “Faceted Crystallites” (Thermo Fisher Nova 200 Nanolab SEM/FIB)

This is a secondary electron image of outer oxide particles formed on 316L stainless steel exposed to 320ºC hydrogenated water for 72 hours to simulate nuclear reactor core corrosion. These particles derive their crystallographic orientation from the underlying metal yielding common facets among separate particles. 


Li-Jen Yu, “Doodle Drawing by an Alloy” (JEOL 2100F TEM)

A recolored STEM (scanning transmission electron microscope) image of dislocation loops and defects in an irradiated Ni-Cr alloy. Excessive point defects such as vacancies and interstitials are created in the alloy after irradiation. Once interstitials accumulate on certain crystallographic planes, dislocation loops can form. These dislocation loops can significantly affect the mechanical properties of the alloy. 

Insung Han, “Dried Flowers (Thermo Fisher Helios 650 Nanolab SEM/FIB)

Metastable Al-Mn quasicrystals formed by short-pulse laser irradiation, modified to show the dendrites’ resemblance to blooming flowers.

Ziwen Zhu, “Circulating tumor cell interacting with cancer associated fibroblast derived extracellular matrix” (Thermo Fisher Nova 200 Nanolab SEM/FIB)

This is an organoid model we built for circulating tumor cell. CTC was captured by the extracellular matrix and grown with cancer associated fibroblast together.
