Responses of soil respiration and its temperature sensitivity to nitrogen and phosphorus depositions in a riparian zone.

Nitrogen and phosphorus depositions and global warming have continuously intensified, impacting soil respiration. However, the response mechanisms of soil respiration rate (R) and its temperature sensitivity (Q) to nitrogen and phosphorus depositions are still unclear, especially for riparian zones. Intact Fluvisols were collected at different water-level elevations (150, 160, 170, and 180 m) of the riparian zone of the Three Gorges Reservoir, China and incubated under 20 and 30 °C with additions of nitrogen (36 kg N ha yr), phosphorus (0.

Porphyrinic based hydrogen-bonded organic framework/TiO nanocomposites for efficient photocatalytic degradation of sulfadiazine.

Porphyrinic hydrogen-bonded organic frameworks (porph-HOFs) have emerged as highly promising materials in the realm of photocatalysis due to their remarkable attributes, including low density, high surface area, efficient visible light absorption, and notable chemical stability. However, the rapid recombination of photogenerated charges remains a significant concern. In this work, a novel HOF-based photocatalyst, PFC-72/TiO was successfully designed with visible light response and high electron transfer capability.

Migration and Transformation of Taxane Allelochemicals in Soil.

The migration and transformation of allelochemicals are important topics in the exploration of allelopathy. Current research on the migration of allelochemicals mostly uses soil column and thin layer methods and verifies it by sowing plant seeds. However, traditional methods inevitably ignore the flux caused by the movement of allelochemicals carried by water.
