Summary: Pyrolysis is a promising technique for the sustainable utilization of heavy metal hyperaccumulators from phytoremediation. This study found that high pyrolysis temperature and low PVC addition promoted the volatilization of Cd and Zn, while high PVC addition suppressed heavy metal volatilization. The addition of PVC increased biochar yield but also elevated Cd and Zn leaching, indicating a dual effect on heavy metal separation and biochar production.

Summary: Novel biochar-based nanocatalysts loaded with Ni/Ca/Fe nanoparticles were prepared by one-step impregnation method for catalytic steam gasification of biomass, which showed improved tar elimination and syngas production. The evenly distributed metal particles with a particle size of less than 20 nm were found to significantly increase H2 yield and tar conversion. Fe-loaded biochar exhibited the best catalytic gasification performance, with 87% tar conversion and 42.46 mmol/g H2 production, indicating its promising potential for hydrogen-rich syngas production.

Summary: Machine learning was used to predict the important factors affecting phytoextraction efficiency of hyperaccumulators. Heavy metal properties, especially the metal ion radius, were found to be the most important factors, while the plant family had the most influence on the bioconcentration factor, metal extraction ratio, and remediation time. The Crassulaceae family showed the highest potential as hyperaccumulators, related to gene expression and substance secretion. The insights from the machine learning model interpretation could guide efficient phytoremediation.

Summary: Arsenic and copper are common co-contaminants in soils, and their accumulation and distribution in As-hyperaccumulator Pteris vittata are influenced by their interactive effects. Increasing arsenic concentration reduces copper accumulation in fronds, while copper does not affect arsenic accumulation. P. vittata accumulates more copper than arsenic in roots, contributing to the low translocation of arsenic.

Summary: Accurate description of Cd micro-zone distribution and accumulation is crucial for understanding Cd transfer and transformation processes. This study used X-ray micro-computed tomography and scanning electron microscope-energy dispersive spectroscopy to visualize the heterogeneous distribution of Cd in and around soil pores. The distribution of Cd around pores was found to be influenced by pore sizes, with macro and mesopores showing preference for the micro-zone within 167.5-335 μm from pores, and micropores exhibiting the highest Cd content within the micro-zone of 67-167.5 μm from pores. Fe and P were identified as key factors contributing to Cd micro-zone distribution around air space and water-holding pores. These findings provide new insights into Cd retention mechanisms and its migration and transformation behavior.

Summary: This study reveals that autophagy serves as an important regulatory pathway for grain yield and quality in rice, and mutations of OsATG9b and OsATG13a genes can affect grain size and quality. Moreover, the TGW6 gene interacts with OsATG8 and is recruited to the autophagosome for degradation, thereby further regulating grain development. Therefore, autophagy plays a crucial role in grain size and quality in crops.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
