From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance
Advanced Optical Materials, EarlyView.Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings

On Coefficient problem for bi-univalent analytic functions
, 2017 Estimates for initial coefficients of Taylor-Maclaurin series of bi-univalent functions belonging to certain classes defined by subordination are obtained. Our estimates improve upon the earlier known estimates for second and third coefficient. The bound for the fourth coefficient is new.

Advanced Sustainable Systems, EarlyView.Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Advanced Science, EarlyView.This study represents the first application of a Keggin‐type polyoxometalate, caesium phosphomolybdate (CPM), as a bifunctional redox catalyst for rechargeable Li–CO2 batteries. CPM significantly reduced the potential gap between discharge and charge reactions to 0.67 V, outperforming most reported catalysts. It also exhibited a high discharge capacity
