Predicting Cd accumulation in rice and identifying nonlinear effects of soil nutrient elements based on machine learning methods.

The spatial mismatch of Cd content in soil and rice causes difficulties in environmental management for paddy soil. To investigate the influence of soil environment on the accumulation of Cd in rice grain, we conducted a paired field sampling in the middle of the Xiangjiang River basin, examining the relationships between soil properties, soil nutrient elements, Cd content, plant uptake factor (PUF), and translocation factors in different rice organs (root, shoot, and grain). The total soil Cd (Cd) and available Cd (Cd) contents and PUF showed large spatial variability with ranges of 0.

The Improvement in Hydrogen Storage Performance of MgH Enabled by Multilayer TiC.

MgH has become a hot spot in the research of hydrogen storage materials, due to its high theoretical hydrogen storage capacity. However, the poor kinetics and thermodynamic properties of hydrogen absorption and desorption seriously hinder the development of this material. Ti-based materials can lead to good effects in terms of reducing the temperature of MgH in hydrogen absorption and desorption.

Factors influencing the effectiveness of liming on cadmium reduction in rice: A meta-analysis and decision tree analysis.

Lime is widely applied as a soil amendment to reduce the grain cadmium (Cd) content in rice production. However, the effectiveness of liming on grain Cd reduction is inconsistent and often cannot meet the safety requirements established for rice production. To identify the factors causing the effectiveness of liming to vary, we collected data from peer-viewed articles regarding lime application in paddy soils that were published during the last ten years.
