Summary: Biochar is a carbon-rich solid derived from biomass through thermal treatment in an oxygen-limited environment. Its structural and electrochemical properties can be optimized through customization techniques like increasing porosity, enlarging surface area, enhancing graphitization, and modifying surface functionalities with heteroatoms. This review mainly focuses on the preparation strategies of biochar-based materials for energy and hydrogen storage, as well as the tuning and optimization of their structural properties for specific applications. The hierarchical porous structure with heteroatom surface functionalities is desirable for supercapacitor application, while the graphitic structure and interlayer spacing are critical for battery applications. High surface area, micropore-dominant structure, and oxygen-rich functional groups are required for H2 storage in biochar.

Summary: Excessive use of tetracycline in livestock farming has caused serious pollution. A new method proposed the catalytic thermal degradation of tetracycline using iron-based metal-organic frameworks (MOFs) and studied the mechanism. The annealing derivatives of three Fe-based MOFs showed better degradation performance than the raw materials due to the exposure of Fe-O clusters and the formation of oxygen vacancies. The optimum sample exhibited a degradation efficiency of 94.22% for tetracycline within 60 minutes at 70 degrees C.

Summary: In this study, a novel electrodialysis system with a self-growing titanium dioxide nanowire (TiO2 NW) electrode is proposed to recover NH3-N and remove heavy metals from manganese residue leachate (MRL), which can seriously affect the environment. Plant growth experiments and ecotoxicity studies are conducted to evaluate the ecological risks of the reuse of recovered NH3-N. The results show that the electrodialysis system can achieve high removal rates of heavy metals and recovery of NH3-N from MRL, and the recovered NH3-N can promote plant growth and optimize soil fertility.

Summary: Metal components have significant impacts on the generation of persistent free radicals (PFRs) in biochar. This study investigates the effect of interactions among metal components on the formation of PFRs during biomass pyrolysis. The results show that the coupling of Fe with Co and Ni increases the abundance of PFRs in iron-containing biochars (IBCs), while Zn inhibits PFRs generation. Persulfate activation experiments confirm that PFRs are critical redox sites. NiFeO/BC is identified as a more efficient catalyst for PFRs activation. This study provides new methods for regulating PFRs in biochar and advances the understanding of metal-containing biomass pyrolysis processes.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
