Article Synopsis
- - This study investigates how adding various elements (like In, Si, and V) to CuP alloys affects their mechanical properties, especially focusing on shear resistance, stiffness, and compressive resistance.
- - Using advanced computational methods, the research demonstrates that strategic doping can significantly enhance properties like plasticity and stability in these alloys.
- - The findings are validated through experiments on doped specimens, offering a reliable framework for predicting how alloying can optimize the mechanical characteristics of CuP materials for future applications.
Floodplain lakes share characteristics of both deep and shallow lakes throughout any given year. Seasonal fluctuations in their water depth drive changes in nutrients and total primary productivity, which directly and indirectly affect submerged macrophyte biomass. To investigate how water depth and environmental variables affect submerged macrophyte biomass, we surveyed six sub-lakes in the Poyang Lake floodplain, China, during the flood and dry seasons of 2021.

- Hydrological gradient variations in wetlands directly influence carbon storage by affecting soil nutrients and plant diversity, although the underlying mechanisms are not fully understood.
- The study found that high-frequency wet-dry alternating zones (HFWA) had significantly higher soil nutrient levels, plant biomass, and carbon content compared to low-frequency wet-dry alternating zones (LFWA).
- A structural equation model showed that wet-dry alternations positively correlate with both soil nutrients and plant biomass, suggesting that better water management in wetlands can boost plant growth and enhance soil carbon sequestration.
[Effects of Phyllostachys edulis expansion on soil nitrogen mineralization and its availability in evergreen broadleaf forest].

By the methods of space-time substitution and PVC tube closed-top in situ incubation, this paper studied the soil mineralized-N content, N mineralization rate, and N uptake rate in Phyllostachys edulis-broadleaf mixed forest (PBMF) formed by P. edulis expansion and its adjacent evergreen broadleaf forest (EBF) in Dagangshan Mountain of Jiangxi Province, China. There existed the same spatiotemporal variation trend of soil total mineralized-N (TMN) content between the two forests.
