A Versatile‐Designable Framework for Active and Programmable Shape‐Morphing Soft Matter Systems: From Inverse Design to Closed‐Loop Control

Advanced Science, EarlyView.
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone

Chemistry – A European Journal, EarlyView.
A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.
