Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

Advanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Advanced In Vitro Platforms for Experimental Liver Research: From Organoids and Liver‐on‐Chip to Omics and Artificial Intelligence

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Hepatocytes perform essential physiological functions in the human body. Gaining more profound insight into the liver structure, diseases, and physiology by using in vitro models can help to propose more relevant clinical applications. Conventional in vitro liver models, such as two‐dimensional (2D) cell cultures, fail to adequately replicate ...
