Colloid driven low supersaturation crystallization for atomically thin Bismuth halide perovskite

open access: yesNature Communications, 2023
It is challenging to grow atomically thin non-van der Waals perovskite due to the strong electronic coupling between adjacent layers. Here, we present a colloid-driven low supersaturation crystallization strategy to grow atomically thin Cs3Bi2Br9.

Wearable microPosters

open access: yesmicroPublication biology, 2019
One barrier to communication at large face-to-face meetings, especially those focusing on scientific or technical topics, is a rapid way to understand what a person knows and thinks about before initiating a conversation. We have devised and reduced to practice an effective way to accomplish this task, the wearable microPoster.
