This study investigates the formation of atmospheric molecular clusters containing ammonia (NH₃, A), methylamine (CH₃NH₂, MA), or dimethylamine (CH₃NHCH₃, DMA) with nitric acid (HNO₃, NA) using quantum mechanics.

Fragile ecosystems (Western Ghats and Himalayas), and major rice cultivation areas are vulnerable to highest Hg deposition. Indian anthropogenic emissions strongly influence deposition fluxes with varying regional impacts.

The geochemical composition of sediment cores can serve as a proxy for reconstructing past human and nature-driven environmental and climatic changes.

Chemical profiling of artificial turf crumb rubber reveals time-based trends in transformation products and transport pathways.

Artemisia annua litter produced in soil contaminated with 15 and 30 g kg⁻¹ of petroleum exhibited significantly lower decomposition rates than that from uncontaminated soil.

Coccolithophores are biogeochemically and ecologically important phytoplankton that produce calcium carbonate scales, or coccoliths. Here, we show that one species of coccolithophore grows coccoliths with uneven distribution of Sr, in contrast to current fractionation model theory.

The physiological and biochemical behaviors of Pseudomonas aeruginosa were modulated using benzalkonium chloride, potentially through the attenuation of the quorum sensing system.
