Simulations are used to probe the interfacial forces contributing to the conformational behavior and corroborate FTIR and atomic force microscopy (AFM) observations.\u0026nbsp; The simulations will be used to calculate the magnitude of interfacial forces and map individual molecular motion overtime. And, finally, we correlate interfacial assembly with mechanical performance and apply these findings to drive material design. Mechanical performance will be evaluated at the macro and nanoscales using quantitative nanomechanical mapping, force distance spectroscopy, and buckling tests.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Biopolymer and Synthetic Polymer Nanocomposite Reinforcement via Interfacial Assembly"}],"uid":"27707","created_gmt":"2018-05-29 19:16:39","changed_gmt":"2018-05-29 19:16:39","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-05-31T12:00:00-04:00","event_time_end":"2018-05-31T14:00:00-04:00","event_time_end_last":"2018-05-31T14:00:00-04:00","gmt_time_start":"2018-05-31 16:00:00","gmt_time_end":"2018-05-31 18:00:00","gmt_time_end_last":"2018-05-31 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
