A Low‐Symmetry FeII Tetrahedron From a Flexible Tritopic Ligand
Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.A highly symmetric and flexible tris‐bidentate tritopic ligand forms an S4 meso homoleptic face‐capped FeII tetrahedron near‐quantitatively in acetonitrile. The addition of nitromethane solvent causes partial isomerization of this meso cage to the racemic homochiral tetrahedron, with the complexity of the system being moderated through solvophobic ...

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, Volume 38, Issue 41, 22 July 2026.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
