The xylan backbone has an affinity to cellulose and will adsorb irreversibly on cellulosic surfaces, an inherent property that provides great opportunities for the use of xylan in cellulose-based composites. This study shows how foams of xylan and nanocrystalline cellulose can be formed by using the freeze-casting technique. Effects of xylan molecular structure and solidification conditions on pore morphology are demonstrated and different ways to stabilize the formed structures are presented. Furthermore, it is shown how crosslinking during the freeze-casting process enables production of nanoreinforced hydrogels with tailored porous structures.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EIPST Visiting Research Professor Dr. Tobias Kohnke speaks on \u0022Ice Templated Xylan-Nanocrystalline Cellulose Aero\/Hydrogels\u0022\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"The topic is \u0022Ice Templated Xylan-Nanocrystalline Cellulose Aero\/Hydrogels.\u0022"}],"uid":"1","created_gmt":"2012-03-16 13:47:17","changed_gmt":"2016-10-08 01:58:25","author":"Jupiter","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-03-22T17:15:00-04:00","event_time_end":"2012-03-22T18:00:00-04:00","event_time_end_last":"2012-03-22T18:00:00-04:00","gmt_time_start":"2012-03-22 21:15:00","gmt_time_end":"2012-03-22 22:00:00","gmt_time_end_last":"2012-03-22 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":["free_food"],"related_links":[{"url":"http:\/\/ipst.gatech.edu\/","title":"Institute of Paper Science and Technology"}],"groups":[{"id":"1182","name":"General"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:lavon.harper@ipst.gatech.edu\u0022\u003ELavon Harper\u003C\/a\u003E\u003Cbr \/\u003EInstitute of Paper Science and Technology\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
