Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Strain‐Induced Failure Mechanisms of Silicon Oxide PECVD Barrier Coating Systems on PET: Experimental Analysis and Simulation of Crack‐Mediated Permeation

Plasma Processes and Polymers, Volume 23, Issue 3, March 2026.
SiOₓ PECVD barrier coating systems on PET lose their barrier function at 5% strain (single loading) or 3% strain (cyclic loading). Simulations reveal that crack offset patterns can reduce permeation by up to 81% through tortuous path effects, though sub‐resolution defects significantly contribute to barrier failure.

Enhanced Spectral Range of Strain‐Induced Tuning of Quantum Dots in Circular Bragg Grating Cavities

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Experimental measurements and finite element simulations together reveal how stiff coating restores strain tunability in circular Bragg grating (CBG) quantum dot devices. Filling the CBG trenches with Al2O3 coating recovers up to 98% of the planar strain (εxx) while preserving cavity performance, enabling bright and tunable quantum light sources ...

Synergistic Meta‐Perforated Substrates for Hypersensitive Crack‐Based Strain Sensors

Small Structures, Volume 7, Issue 3, March 2026.
This work presents a mechanical meta‐perforated substrate that significantly enhances infinitesimal‐strain sensitivity in crack‐based sensors. Integrating a re‐entrant mechanical meta‐structure with perforations yields a 760‐fold sensitivity increase at 0.1% strain. The approach amplifies local deformation through synergistic strain and Poisson's‐ratio
