Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.This work shows the first proof‐of‐concept for fully self‐healing and stretchable coplanar waveguide (CPW) transmission line using printable electrically conductive liquid metal elastomer. RF performance was evaluated in frequency ranging from 1 to 6 GHz under uniaxial tensile strain up to 100%, after self‐healing, and for 1000 cyclic stretch‐release ...

Rare 3 × 3 Layering in High‐Pressure Pseudo‐Perovskite Sr4Te4O15
ChemistryOpen, Volume 15, Issue 2, February 2026.High‐pressure/high‐temperature synthesis, crystal structure determination, and characterization of Sr4Te4O15, a rare (110)‐oriented pseudo‐perovskite with 3 × 3 corrugated oxotellurate layers, are presented. Thermal stability was studied by temperature‐dependent X‐ray powder diffraction. UV‐Vis, IR, and Raman spectroscopy, as well as density functional
