High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Scaffold Dependent Coordination Modes of Chelating PEP‐Type Ligands in Iron(0) Carbonyl Complexes (E = O, S)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The reaction of iron pentacarbonyl with various chelating diphosphine ligands containing oxygen or sulfur atoms in their backbone yields complexes that exhibit noteworthy coordination behavior. Depending on the natural bite angle of the ligands and the coordination behavior of the heteroatom, preferences regarding the coordination geometry are verified

Defining AV2‐1 as a novel pharmacological probe to target human and rodent TRPV2

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Transient receptor potential vanilloid 2 (TRPV2) is a non‐selective cation channel implicated in immune cell functions. However, progress in understanding TRPV2 has been limited by a lack of potent and selective pharmacological tools, particularly those targeting the human variant. We aimed to identify and characterise a

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,
