Summary and Overview of the Odour Regulations Worldwide

This review finds a wide range of approaches to odor regulation worldwide, from non-existent to highly detailed. It highlights the challenges in creating standardized policies due to the subjective nature of odor perception, varied regulatory systems, and complex socio-economic factors. The paper also emphasizes the need for continued development and adjustment of odor legislation for sustainable development.

Mitigation potential of global ammonia emissions and related health impacts in the trade network

The study found that about one-fourth of global agricultural ammonia emissions are trade-related, causing significant PM2.5 pollution and related health impacts (61,000 premature deaths) globally. The researchers identified three trading communities and proposed targeted, community-based strategies for mitigating ammonia emissions through trade structure adjustments and technological advancements.

Coordination tailoring of Cu single sites on C3N4 realizes selective CO2 hydrogenation at low temperature

This study demonstrates that Cu single atoms supported on C3N4, with tailored coordination structures (Cu-N4 and Cu-N3), can serve as highly active and selective catalysts for CO2 hydrogenation at low temperatures. The Cu-N4 SAC exhibits exceptional CH3OH selectivity (95.5%) and productivity (4.2 mmol g⁻¹ h⁻¹) at 150 °C, outperforming commercial Cu-ZnO/Al2O3 catalysts. DFT calculations suggest different reaction pathways for CH3OH and CO formation on Cu-N4 and Cu-N3 SACs, respectively.
