Freeze Casting of Aluminium Nitride
Advances in Science and Technology, 2006Aqueous freeze casting is an alternative wet shaping technique where water-based ceramic suspensions containing a cryoprotectant are cast in molds, frozen and dried. The method can be applied to various ceramic systems depending mainly on the ability to produce high solid loading in aqueous ceramic slurries.

Cellularized Cellular Solids via Freeze‐Casting
Macromolecular Bioscience, 2015The elaboration of metabolically active cell‐containing materials is a decisive step toward the successful application of cell based technologies. The present work unveils a new process allowing to simultaneously encapsulate living cells and shaping cell‐containing materials into solid‐state macroporous foams with precisely controlled morphology.

Hydrogels improvements through freeze-casting and anti-freezing additives
2021Freeze-casting is a widely applied processing route for numerous kinds of materials, including gels. As obtained pores are a «negative» of the frozen solvent, improvements in porosity control can be achieved by anti-freezing macromolecules addition.

Freeze Casting for Assembling Bioinspired Structural Materials
Advanced Materials, 2017AbstractNature is very successful in designing strong and tough, lightweight materials. Examples include seashells, bone, teeth, fish scales, wood, bamboo, silk, and many others. A distinctive feature of all these materials is that their properties are far superior to those of their constituent phases.

Gradient-controlled freeze casting of preceramic polymers
Journal of the European Ceramic Society, 2023Solidification is the foundation upon which freeze casting is built, and this work seeks to understand the solidification process in freeze casting, especially with respect to the growth of dendrites. To this end, two solidification parameters, freezing front velocity and temperature gradient, were independently controlled using a gradient-controlled ...

Control of Porosity in Freeze Casting
JOM, 2020Many biologic structural materials have porous microstructures with a distribution and orientation of pores that are challenging to achieve using traditional methods of processing. In this investigation, numerical and experimental methods of evaluation were used to understand effects from the primary processing parameters on the temperature gradients ...

Magnetic freeze casting inspired by nature
Materials Science and Engineering: A, 2012Abstract Magnetic field aligned freeze casting is a novel method to fabricate porous, anisotropic ceramic scaffolds with a hierarchy of architectural alignment in multiple directions. A weak rotating magnetic field applied normal to the ice growth direction in a uniaxial freezing apparatus allowed the manipulation of magnetic nanoparticles to create ...
