| Abstract Scope |
Magnetic freeze-casting is a promising technique for creating porous structures replicating the impressive mechanical properties of human bone. Doing so using Helmholtz Coils is of interest due to the highly uniform fields they generate and the low cost of implementation. Though high in uniformity, Helmholtz Coils lack strength which limits their use in magnetic freeze-casting. In this work a method using Helmholtz Coils to control mechanical properties of surface-magnetized alumina freeze-cast scaffolds enabled by unique slurry properties of mixed scaffolds (1:1 ratio of particle and platelet shaped alumina) via the Hall Effect is developed. Prior to these findings the Hall Effect has never been seen in freeze-cast slurries nor has it been applied for control purposes in any of its other applications. Work to better understand the factors at play in mixed alumina scaffolds will increase control of mechanical properties to increase applicability in aerospace, biomedicine, and dental implants. |
