Pressure‐Induced Structural and Optoelectronic Modulations in 2D Dion‐Jacobson Hybrid Lead Iodide Perovskites With a Rigid Spacer

Advanced Optical Materials, EarlyView.
Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

Emerging Hydrochromic Metal Halide Perovskites

Advanced Optical Materials, EarlyView.
Hydrochromic metal halide perovskites (MHPs) are promising candidates for next‐generation smart optical materials owing to their excellent responsiveness, superior reversibility, and highly tunable emission. This review summarizes the latest progress in hydrochromic MHPs and provides general principles for the rational design of advanced hydrochromic ...

Cs2AgBiBr6 Perovskites: Designing Stable, Sensitive and Selective Eco‐friendly Ozone Sensors

Advanced Sensor Research, EarlyView.
An eco‐friendly ozone (O3) sensor made from lead‐free Cs2AgBiBr6 double perovskite is presented. It operates efficiently at room temperature with low energy consumption, overcoming the limitations of traditional metal‐oxide‐based sensors. The optimized morphology design enhances ozone detection and demonstrates high selectivity for ozone over other ...

On univalent spirallike log-harmonic mappings

AIMS Mathematics
This study investigates univalent log-harmonic mappings, a class of functions that map the unit disk into the complex plane. First, we establish the necessary and sufficient conditions for univalent log-harmonic mappings to map the unit disk onto a ...

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

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 ...
