[18] Understanding nonliear rheology in anisotropic colloids: a review

Yul Hui Shim*
Korea-Australia Rheology Journal 2025, accepted. 

[17] Reversible control of rheological properties in microgel composite via nanoparticle aggregation 

Yul Hui Shim*; Tae Yeon Kong; So Youn Kim*
ACS Applied Materials & Interfaces 2025, 17 (27), 39616 - 39627. (link)

Our study demonstrates that nanoparticle aggregates reversibly control the rheological properties of microgel, acting as physical cross-linkers.  If you are interested in direct-ink-writing printing, ink rheology, and recovery rheology, this study will provide insights. 

[16] Linking structural and rheological memory in disordered soft materials

This work is one of the recent achievements in recovery rheology. Now, we can clearly relate structural and rheological memory by acknowledging the recoverable strain.

[15] Is low polydispersity always beneficial? Exploring the impact of size polydispersity on the microstructure and rheological properties of graphene oxide

Eun Ho Cho; Yul Hui Shim*; So Youn Kim*
ACS Applied Materials & Interfaces 2024, 16, 55913-55924. (link)

Our study demonstrates that high PDI in GO enhances rheological properties through improved microstructural alignment. If you are interested in colloidal dispersion, printable inks, or structure-property relationship in soft materials, this study will provide insights.
