I earned my B.S. in Advanced Materials Engineering of Kookmin University. I am in master course under Professor Heeman Choe in Kookmin University. I am working as visiting scholar in Dunand Reasearch Group (Sep. 2018 – Feb. 2019). I studied effects of powder carrier on the morphology and mechanical properties. I manufactured two type of iron foams by controlling solvents : water and camphene. The water-based iron foam shows the typical morphology of aligned lamellar macropores replicating ice dendrites along the parallel direction to the temperature gradient. On the other hand, the camphene-based iron foam shows the structure with nearly identical round pores.
At Northwestern, I will manufacture camphene foam with aligned lamellar pore structure, and I will study iron oxide redox cycles using three different types of samples : water-based iron foam with aligned lamellar pore structure and camphene-based iron foams with aligned dendritic pore structures and equiaxed pore structures.
