The MCF hosts a running image contest that resets monthly. In addition to displaying some of the imaging and analysis capabilities of our labs, it gives our users a chance to display their creative side. Check back here at the first of each month for updates on monthly awardees and twice a year – around mid-January and mid-June – to see the semiannual grand prize winners.
If you are an MCF user, then check out the contest rules here and please consider submitting.

of scales make the wing very light despite its size. The structure illustrates how lighter, softer materials (i.e., not metals or concrete) can be used to generate strong resilient structures.

This image is obtained for René 142 additively manufactured using a Scanning Laser Epitaxy (SLE) process currently being developed at Georgia Tech.
During melting and re-solidification, the alloying elements segregate and create fascinating microstructural features such as these eutectic pools. Studying these pools is necessary to eliminate them in the final product as they reduce component life.
These nanocubes have greater resistance to degradation under acidic conditions due to their specific surface facet termination.

More Info:Beginnings of Hydrated CSA cement structure: Only thirty minutes after initial contact with water, the formation of ettringite crystals, which form the hardened crystal structure of a hydrated calcium sulfoaluminate (CSA) cement, begins. CSAs are a greener alternative to portland cements, but many aspects of their hydration, structure, and performance are not yet well understood. By increasing our knowledge of these materials at microstructural levels we can optimize their usability and durability while at the same time decreasing the environmental footprint of new construction.
