Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Strong Coupling in all‐Polymer Planar Microcavities

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.
Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

Strain‐Preserving Transfer of Freestanding Oxide Membranes for Tunable Magnetic Anisotropy

Advanced Science, Volume 13, Issue 47, 24 August 2026.
An epoxy‐assisted exfoliation and transfer strategy circumvents the trade‐off between structural flexibility and strain tunability in freestanding oxide membranes. Epitaxial strain is effectively preserved, enabling versatile and robust control of magnetic anisotropy without sacrificing flexibility.

Photonic nanovoids for tailored optoelectronic response in silicon solar cells

Responsive Materials, Volume 4, Issue 3, August 2026.
Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.
