Uranium Doped Gallium Nitride Epitaxial Thin Films
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...

This article provides an overview of the current state of the art and future improvements in PV technology and explains how changes in the technology and design of individual PV components—at the module level, the balance‐of‐system (BOS) level, or the PV plant level—can affect the reliability, durability, and energy output of a PV system.

The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

γ‐Cyclodextrin‐Based 2:2 Host–Guest Complexes With Emergent Circularly Polarized Luminescence
We elucidate the formation of γ‐cyclodextrin‐mediated 2:2 host–guest complexes through combined NMR, thermodynamic, and kinetic analyses. The process is driven by dimerization and yields discrete assemblies with emergent chiroptical properties via host‐to‐guest chirality transfer.

A pair of π‐extended chiral triangular prisms based on pyromellitic diimide is synthesized from enantiopure macrocyclic precursors. They exhibit orange fluorescence and solvent‐dependent self‐assembly, enabling chiroptical inversion and amplification with |glum| values up to 1.15 × 10−2. Single‐crystal structures reveal solvent‐controlled conformations
