Purposefully designed chelators bridge these domains by enhancing the biological performance of metal ions and by enabling the enrichment, isolation, and separation of technologically critical metals. This presentation highlights our group\u2019s recent efforts in chelator design for these two areas. In the first part, we survey how expanded macrocyclic chelators can be engineered for nuclear medicine. Our studies show that introducing controlled flexibility into these ligands allows them to adjust their binding conformations to accommodate metal ions of varying sizes, increasing their versatility for radiometal-based applications. The second part focuses on applying this chelator class to the extraction and separation of rare earth elements, critical minerals central to modern technologies. We demonstrate how rationally tailored chelators can selectively remove and enrich rare earths from complex matrices and enable efficient interelement separations. Together, these studies illustrate how fundamental principles of coordination chemistry can be leveraged to meet distinct challenges in nuclear medicine and critical mineral processing.", "occurrence_notes":null, "guid":"142066-21889963@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/142066", "building_id":"1000158", "building_name":"Chemistry Dow Lab", "campus_maps_id":"34", "room":"1640", "location_name":"Chemistry Dow Lab", "has_livestream":0, "cost":"", "tags":["Chemistry"], "website":"", "sponsors":[ { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21889963 } , "140717-21887527": { "datetime_modified":"20260201T175959", "datetime_start":"20260217T160000", "datetime_end":"20260217T170000", "has_end_time":1, "date_start":"2026-02-17", "date_end":"2026-02-17", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Colloquium: Automorphic representations and optimal quantum logic gates", "occurrence_title":"", "combined_title":"Colloquium: Automorphic representations and optimal quantum logic gates: Rahul Dalal, Succinct", "event_subtitle":"Rahul Dalal, Succinct", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"In this talk, I will describe a surprising connection between the Langlands program and designing efficient architectures for quantum computing. Constructions of quantum computers require finding finite sets of 2^n-by-2^n unitary matrices that efficiently and computably approximate arbitrary unitary matrices through short products. Extending ideas first used in Lubotzky-Phillips-Sarnak's construction of expander graphs, such an \"optimal covering\" property can be translated into a bound in the theory of automorphic representations. I will explain this translation and then broadly sketch how recent progress in automorphic theory and the Langlands program can be applied to prove the resulting bound in the cases most relevant to quantum computing.", "occurrence_notes":null, "guid":"140717-21887527@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/140717", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Applied Mathematics","Mathematics"], "website":"", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" }, { "group_name":"MCAIM - Department of Mathematics", "group_id":"4897", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/11\/event_140717_original-3.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/11\/crop-event_140717_original-3.png" }, "occurrence_count":1, "first_occurrence":21887527 } }
