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

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
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 ...

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates the use of 2D materials drum resonators to generate and modulate radio‐over‐laser signals. Taking advantage of the self‐sustained oscillations arising in cavity optomechanical systems by a continuous wave visible laser, a radio frequency signal is generated and frequency‐modulated by just changing a DC gate voltage.

Diffusion–Model–Driven Discovery of Ferroelectrics for Photocurrent Applications

Advanced Science, Volume 13, Issue 31, 4 June 2026.
We developed a diffusion model–based generative AI and high‐throughput screening framework that accelerates the discovery of photovoltaic ferroelectrics. By coupling AI driven crystal generation with machine learning and DFT screening, we identified Ca3P2 and LiCdP as new ferroelectric materials exhibiting strong polarization, feasible switching ...
