External Field Assisted Freeze Casting [PDF]
Ceramics, 2019 Freeze casting under external fields (magnetic, electric, or acoustic) produces porous materials having local, regional, and global microstructural order in specific directions. In freeze casting, porosity is typically formed by the directional solidification of a liquid colloidal suspension.

Ambiguities in statistical calculations of nuclear fragmentation [PDF]
, 2004 The concept of freeze out volume used in many statistical approaches for disassembly of hot nuclei leads to ambiguities. The fragmentation pattern and the momentum distribution (temperature) of the emanated fragments are determined by the phase space at ...

Study of Ceramic Slurries for Investment Casting with Ice Patterns [PDF]
, 2004 Ice patterns generated by rapid freeze prototyping or a molding process can be used to make ceramic investment molds for metal castings. Due to the use of ice, the ceramic slurries must be poured around the pattern and cured at sub-freezing ...

Freeze-casting porous chitosan ureteral stents for improved drainage. [PDF]
Acta Biomater, 2019 As a new strategy for improved urinary drainage, in parallel to the potential for additional functions such as drug release and self-removal, highly porous chitosan stents are manufactured by radial, bi-directional freeze-casting. Inserting the porous stent in to a silicone tube to emulate its placement in the ureter shows that it is shape conforming ...

Isotropic freeze casting of through-porous hydroxyapatite ceramics
Journal of Advanced Ceramics, 2019 It has well known that hydroxyapatite (HA) is a kind of excellent materials for biomolecular absorption and separation, and the absorption and separation performances of HA would be improved if HA had been processed into desirable porous structures.
