Micropollutants and Their Interactions With Relevant Environmental Viruses

Environmental Microbiology, Volume 27, Issue 10, October 2025.
Environmental micropollutants increase virus stability. ABSTRACT Emerging pollutants encompass a diverse array of chemicals classified as micropollutants, including pharmaceuticals and microplastics (MPs). Viruses are known to adsorb onto MPs, including binding to bacterial biofilms that form the plastisphere.

Exposure to Rice Straw Ash Alters Survival, Development and Microbial Diversity in Amphibian Tadpoles

Ecology and Evolution, Volume 15, Issue 7, July 2025.
This study examined how aqueous ash extracts (AEA) from rice straw burning impact R. dybowskii tadpoles, revealing that higher concentrations (up to 6 g L−1) over 28 d reduced survival, impaired growth, and disrupted skin and gut microbiota diversity, with polycyclic aromatic hydrocarbons (PAHs) detected in water.

A Triptycene‐Based Cage Host for Aromatic Hydrocarbon Guests

Asian Journal of Organic Chemistry, Volume 14, Issue 6, June 2025.
A molecular cage consisting of two tripodal triptycene units and three diphenylacetylene linkers includes aromatic guests such as anthracene, acenaphthylene, and pyrene into the cavity. The association constants of the host–guest complexation were determined by the 1H NMR titration.

Ecological and Health Risks of Polycyclic Aromatic Hydrocarbons in Particulate Matter in Chinese Cities

GeoHealth, Volume 9, Issue 6, June 2025.
Abstract During the first two decades of the 21st century, the level of polycyclic aromatic hydrocarbon (PAH) pollution in urban atmospheric particulate matter (PM) in China significantly increased. By combining data from more than 6,695 individual samples covering 89 typical cities (population > 0.5 million people) across China, this study focuses on ...

A Stable Carbon‐Centered Radical Showing Six Amphoteric Redox States

Chemistry – A European Journal, Volume 31, Issue 6, January 27, 2025.
A fully conjugated system built by alternate fusion of four benzene and three cyclopentadiene rings is a further rare example of an air‐ and moisture‐stable carbon‐centered hydrocarbon radical. It was synthesized by double ortho fusion and was extensively characterized by spectroscopic and computational methods.

Development of Continuous‐Flow Reactions for the Synthesis of Anti‐Alzheimer Drug Memantine

Chemistry – A European Journal, Volume 31, Issue 5, January 22, 2025.
Memantine hydrochloride, an NMDA receptor antagonist used in Alzheimer's treatment, features an adamantane core with a bridgehead amino group. Its synthesis from acenaphthene involves hydrogenation, skeletal rearrangement, nitration, and reduction. Continuous‐flow reactions were explored for each step to develop a continuous manufacturing process for ...
