Published in 2017 at "ACS applied materials & interfaces"

DOI: 10.1021/acsami.7b01502

Abstract: The temperature ranges where a pure simple-cubic blue phase (BPII) emerges are quite narrow compared to the body-centered-cubic BP (BPI) such that the polymer stabilization of BPII is much more difficult. Hence, a polymer-stabilized BPII… read more here.

Published in 2022 at "ACS nano"

DOI: 10.1021/acsnano.2c02799

Abstract: Many crystallization processes, including biomineralization and ice-freezing, occur in small and curved volumes, where surface curvature can strain the crystal, leading to unusual configurations and defect formation. The role of curvature on crystallization, however, remains… read more here.
