In 2021 Fall semester, the Department of Chemistry and Biochemistry will be holding seminar series every Friday between 3:30pm-4.30pm starting on Sep 3rd (second week of the semester). The seminars will be presented either virtually via BbCollaborate or in person (Room SCI 1.210).

The first seminar of the series will take place on Friday Sep. 3rd and will be delivered virtually (Dr. Kristin Hutchins, Texas Tech University; Host: Dr. Ronald Smaldone). The link can be provided upon request (please contact Dr. Gabriele Meloni at gabriele.meloni@utdallas.edu).

Title: Molecular Motion and Thermal Expansion Properties of Organic Solids

Abstract: Thermal expansion (TE) is the response of a material to a change in temperature. Materials that undergo well-controlled TE are useful in high precision instruments, sensors, and aerospace applications. Controlling and predicting TE behaviors of organic molecular solids connected through noncovalent interactions remains challenging because directing self-assembly of component molecules in three dimensions is not trivial. Here, we describe our efforts to design organic solids that undergo molecular motion in response to temperature as a platform for achieving large TE. We also direct solid-state self-assembly via noncovalent interactions and discuss the impact of these interactions on TE behavior.
