Ice-templated porous alumina structures
TLDR
In this paper, the formation of regular patterns is a common feature of many solidification processes involving cast materials, and regular patterns can be obtained in porous alumina by controlling the freezing of ceramic slurries followed by subsequent ice sublimation and sintering.About:

Stability of a Planar Interface During Solidification of a Dilute Binary Alloy
W. W. Mullins,R. F. Sekerka +1 more
TL;DR: In this article, the stability of a moving planar liquid-solid interface during unidirectional freezing of a dilute binary alloy is theoretically investigated by calculating the time dependence of the amplitude of a sinusoidal perturbation of infinitesimal amplitude introduced into the planar shape.

Freeze casting of hydroxyapatite scaffolds for bone tissue engineering.
TL;DR: It is reported here how freeze casting can be applied to synthesize porous scaffolds exhibiting unusually high compressive strength, e.g. up to 145 MPa for 47% porosity and 65MPa for 56%porosity, which might open the way for hydroxyapatite-based materials designed for load-bearing applications.
