", "abstract": "Provided herein are methods for making a freeze-cast material having a internal structure, the methods comprising steps of: determining the internal structure of the material, the internal structure having a plurality of pores, wherein: each of the plurality of pores has directionality; and the step of determining comprises: selecting a temperature gradient and a freezing front velocity to obtain the determined internal structure based on the selected temperature gradient and the selected freezing front velocity; directionally freezing a liquid formulation to form a frozen solid, the step of directionally freezing comprising: controlling the temperature gradient and the freezing front velocity to match the selected temperature gradient and the selected freezing front velocity during directionally freezing; wherein the liquid formulation comprises at least one solvent and at least one dispersed species; and subliming the at least one solvent out of the frozen solid to form the material.", "date": "2020-04-16", "date_type": "published", "publisher": "U.S. Patent Office", "id_number": "CaltechAUTHORS:20210201-150525983", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20210201-150525983", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Division-of-Biology-and-Biological-Engineering" } ] }, "primary_object": { "basename": "US20200115291A1.pdf", "url": "https://authors.library.caltech.edu/records/6zsvy-3g175/files/US20200115291A1.pdf" }, "related_objects": [ { "basename": "WO2020041759A1.pdf", "url": "https://authors.library.caltech.edu/records/6zsvy-3g175/files/WO2020041759A1.pdf" } ], "resource_type": "patent", "pub_year": "2020", "author_list": "Faber, Katherine T.; Kornfield, Julia A.; et el." } ]
