Two-dimensional ferroelectricity in a single-element bismuth monolayer

Nature, Published online: 05 April 2023; doi:10.1038/s41586-023-05848-5

A single-element ferroelectric state is observed in a black phosphorus-like bismuth layer, in which the ordered charge transfer and the regular atom distortion between sublattices happen simultaneously and ferroelectric switching is further visualized experimentally.

De novo design of modular peptide-binding proteins by superhelical matching

Nature, Published online: 05 April 2023; doi:10.1038/s41586-023-05909-9

A computational approach is used to design modular proteins that bind to synthetic peptides and disordered regions of human proteins with high affinity and specificity.
