Seminar:  Plenty of Room at the Interface: Exploring the Potentials of Micro and Nanostructured Interfaces

Seminar Abstract
The intricate architecture of interfaces harbors a rich ground for physical and chemical interactions, crucial in areas such as filtration, catalysis, and biomedical applications. Precise structured interfaces govern phenomena from microscopic diffusive behaviors to molecular-level reactions, presenting as dynamic platform for scientific exploration and application.

Here, I would like to share my recent research on impact of microstructures in porous media on transport dynamics of confined nanoparticles, aiming at sculpting models for mass transport in complex environment advancing energy-related separation technologies. The studies include modulation of heterogeneity of porous media on the particle's long-time diffusion and trapping duration. Furthermore, I will discuss the utilization of amplified hydrodynamic coupling by interface confinement to facilitate efficient transport of nanoparticles. Into the intricacies of detailed nanoscopic interfacial structures, hierarchical chemical patterns are shown their pivotal roles in controlling chemical reactions such as diacetylene polymerization and silane crosslinking. These reactions markedly diverge from their bulk counterparts, pushing us to rethink structure-function relationship governing interfacial reactions in nanoscale. This re-evaluation forges paths to enhance reaction precision and efficiency, benefiting realms ranging from integrated circuits to the formation of cell-instructive surfaces indispensable in the biomedical research.

Biosketch
Anni started her research journey at Wuhan University, where she earned her BS degree in chemistry. She later pursued PhD research specializing in nanoscale surface patterning, guided by Professor Shelley Claridge at Purdue University. Relocating from Indiana to Colorado, Anni joined the research group of Professor Daniel Schwartz, with a particular focus on exploring interfacial-confined diffusion through single particle/molecule tracking.
