Aerosol Pollutants and Health: Role of Size and Chemical Composition. [PDF]

Public Health Chall
GRAPHICAL ABSTRACT This review article focuses on air pollution arising from natural and human sources, with particle properties influencing health and environmental effects. Modern technology, organ‐on‐a‐chip (OoC), provides promising tools for assessing these impacts. ABSTRACT Air, an essential environmental component that surrounds us everywhere and

Benzo[a]pyrene and benzo[e]pyrene : photoreactivity and phototoxicity towards human keratinocytes

, 2022
Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds derived mostly from the incomplete combustion of fossil fuels and biomass. Human skin can absorb PAHs and the uptake increases with their molar mass and lipophilicity.

Unraveling Soil Organic Matter Dynamics in Tropical Wetlands Through Advanced Thermal and Pyrolytic Approaches

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT The dynamics of soil organic matter (SOM) and humic acids (HA) in a permanent and seasonal wetland located in southeastern Brazil (hydromorphic soils and gramineous vegetation) were assessed through thermogravimetry, evolved gas analysis, and analytical pyrolysis. The n‐alkane series in all samples spanned from C13 to C35, regardless of season,

Chiral Pd2L4 Capsules from Readily Accessible Tröger's Base Ligands Inducing Circular Dichroism on Fullerenes C60 and C70

Angewandte Chemie, Volume 137, Issue 10, March 3, 2025.
A chiral Pd2L4 capsule based on Tröger's base is reported and shown to bind several polyaromatic hydrocarbons (PAH). It shows strong affinity for fullerenes C70 and C60 and is able to extract the latter from complex mixtures. Host‐to‐guest chirality transfer onto the fullerenes is observed by circular dichroism spectroscopy and theoretically analyzed ...

Acid/Base‐Triggered (Chir)Optical Switching and Efficient Singlet Oxygen Generation from a Pyrene‐Extended Azahelicene

ChemistryEurope, Volume 4, Issue 4, April 2026.
A pyrene‐extended azahelicene delivers proton‐switchable NIR absorption, fluorescence quenching, and reversible chiroptical responses (circular dichroism (CD)/circularly polarized luminescence (CPL)), together with efficient singlet oxygen generation (SOG), making it a promising proton‐responsive photofunctional system.

Oral Squamous Cell Carcinoma‐Risk Factors, Diagnosis, Treatment, and Prevention

Cancer Nexus, Volume 2, Issue 2, April 2026.
ABSTRACT Oral squamous cell carcinoma (OSCC) usually originates from the precancerous lesions of oral mucosa and accounts for approximately 90% of oral cancers. In‐depth understanding of pathogenesis, hallmarks, and etiological factors is a crucial prerequisite for advancing the diagnosis and treatment for OSCC patients. This review aims to present the
