Amphidynamic Crystals. Built with rigid components and moving parts, these novel materials are a promising platform for the design of functional materials and artificial molecular machines.

Stimuli-Responsive Amphidynamic Materials

Crystalline Molecular Gyroscopes as Molecular Machines. Dendrimeric mole-cular rotors provide a framework for the rapid dynamics of large rotators in the solid state. They provide us with oppor-tunities to understand and emulate the behavior of bio-molecular machines.

Molecular Gyroscopes: Dipolar Arrays

Nanosocale molecular Rotors As Molecular Machines

Inertial Rotary Dipolar Arrays. Amphi-dynamic crystals based on metal organic frameworks can be built with internal rota-tors displaying controlled motion up to the picosecond time scale at ambient tempe-rature, as determined by cryogenic NMR. Crystals with rotating dipoles are now being used to create new class of multiferroric materials with dipolar order and dynamics determined by dipole-dipole inter-actions and external fields. These materials are expected to display unprecedented materials properties.

Diversity, PI and Group

The Garcia-Garibay research group is characterized by a remarkable wealth of intellectual, cultural, gender, and ethnic diversity. Current and past group members include young scientists from Caucasian, Hispanic, African-American, Mideast, and Asian backgrounds. Out of 50 graduate students and postdoctoral fellows trained in the group, 22 are women. Dr. Garcia-Garibay has been recognized by the UCLA Diversity and Inclusiveness Award in 2013 for his efforts in diversity.

Outreach, Group Group members Geeta Vedehra and Jin Park hosted

Pasadena City College (PCC) students hosted as members of Organization for Cultural Diversity in Chemistry (OCDC) to inform college students of the state of art in chemistry and life in grad school.

Group member Patrick Commins participated in OCDC’s event that hosted Los Angeles Trade-Technical College (LATTC) diversity club undergraduates, gave lab tours and organized a panel to encourage them to apply for grad schools.

Group member Vanessa Breslin visited The Willows Community School and demonstrated chemical experiment to 8th grade students in an event organized by the Chemistry and Biochemistry Graduate Student Association (CBGSA).
