Precision Stress Engineering in Tensegrity‐Inspired Nanoarchitectures Enabled by Size‐Affected Shrinkage

Small, Volume 22, Issue 23, 22 April 2026.
This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.
