4D‐Printed Spin Crossover Metamaterials with Giant Programmable Positive or Negative Thermal Expansion

Advanced Materials, EarlyView.
Spin crossover composite filaments are implemented for the rational design of 4D‐printed mechanical metamaterials. The obtained bi‐material structures guided by a theoretical analysis based on analytical calculations and Finite Element Analysis simulations exhibit giant programmable positive or negative deformation with coefficients of thermal ...

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...
