Microlasers Made Entirely from Edible Substances
Advanced Optical Materials, EarlyView.Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures
Advanced Optical Materials, EarlyView.A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Tunneling in Persistent Luminescence
Advanced Optical Materials, EarlyView.Key experimental criteria are provided for the occurrence of thermal/athermal tunneling and localized transitions. Many experimental studies of PersL have assigned tunneling on the basis of the linear relationship of PersL decay between intensity, I, and time, t−k, where k is a constant or I−1 versus t.

Highly Efficient Upconverted Fluorescence from Coulombically Assembled Ion Pair
Advanced Optical Materials, EarlyView.A dicationic Os(II) complex paired with two monoanionic fluorophores is designed to enable highly efficient triplet–triplet annihilation upconversion, achieving a remarkable upconverted fluorescence quantum yield of 13% at 785 nm excitation with a record‐low threshold intensity of 5.9 mW cm⁻2, attributed to diffusion‐free acceleration of energy ...

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
Advanced Photonics Research, EarlyView.The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Advanced Sustainable Systems, EarlyView.Rigid, lightweight foams for thermal insulation are produced using a universal and scalable method: results are compared between pilot plant trials, four wood residues, pulp, ocean water, and a biosurfactant. Two guidelines for using this method are suggested: use a distribution of rigid wood microparticle sizes and shapes and match the average ...
