Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators

open access: yesAdvanced Materials, EarlyView.
A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...
