“Liquid Crystals of Colloidal Nanoplates”

Title: Liquid Crystals of Colloidal Nanoplates.
When: Tuesday, June 18, (2019), 12:00.
Place: Department of Condensed Matter Physics, Faculty of Sciences, Module 3, Seminar Room (5th Floor).
Speaker: Prof. Zhengdong Cheng, Artie McFerrin Department of Chemical Engineering, TAMU, USA.

Colloidal anisotropic platelets are model systems for discotic liquid crystal investigation. We have systematically studied the ZrP monolayers due to the capability to control the size and surface chemistry. I will discuss our recent research on liquid crystal phase dynamics in colloidal discotic suspensions, particularly the controlled self-assembly under external fields, such as electric and magnetic field and temperature gradient.
