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 the first week 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.

Al Dendrites: Dendrites formed inside a shrinkage porosity during solidification of A365 aluminum alloy.
BaTiO3 Sunspots This is an image of sintered barium titanate silicate glass microspheres that crystallized during sintering. Crystallization initiated at the glass particle boundaries and amorphous glass was pulled from the centers of the larger grains leaving the voids which appear as the “sunspots”. The contraction on crystallization also formed the “shattered glass” pattern since the denser crystalline regions can no longer fill all the available space within the microspheres.
Seeing Tech Everywhere U Look Image of a hoverfly’s compound eyes. The sample was coated with a 2nm thick gold layer enabling the sample to be imaged using a standard SEM.
Elemental Character The image shows the formation of Chinese-script carbides in nickel-based
superalloys that are typically found to be Ta-rich.
during cooling cycle from a high temperature. The EBSD technique is capable of measuring crystal orientations of a material at very high spatial and angular resolution.
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.
appearance with very different colors – like jewels in a mine.
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.
