Summary: The use of hypersaline electrolytes can enhance the efficiency of microbial fuel cells, but the bottleneck of O-2 reducing cathodes still needs to be addressed. By designing efficient halotolerant microbial cathodes, especially focusing on Gammaproteobacteria strains related to Thiohalobacter thiocyanaticus, this issue can be overcome.

Summary: The study investigates the role of external sodium acetate (SA) in improving Cr(VI) reduction and stabilization in Cr(VI)-spiked soils. Batch experiments showed that the addition of SA resulted in a decline in soil Cr(VI) content and an increase in the relative abundances of Cr(VI)-reducing microorganisms. Redundancy analysis indicated that pH and SA were the predominant factors affecting the microbial community. Functional prediction suggested that the addition of SA had a positive effect on the metabolism of key substances involved in Cr(VI) microbial reduction.

Summary: This study investigated the interaction of ZnO nanoparticles, Cr(VI), and Pannonibacter phragmitetus BB, and found that ZnO NPs inhibited Cr(VI) reduction but had no effect on bacterial viability. Cr(VI) induced BB to produce organic acids and release Zn2+ from ZnO NPs. The dissolved Zn2+ promoted Cr(VI) reduction, but hindered Cr(V)/Cr(IV) transformation.

Summary: Cr (VI) is effectively reduced and power is generated in a photocatalytic microbial fuel cell (PMFC) with a WO3/CF anode and a hybrid photocathode of Fe3O4, FeWO4, and CP. This process occurs under both light and dark conditions. The performance of the PMFC is improved by the biocompatibility and enhanced conductivity of WO3 and the heterojunction formed between Fe3O4 and FeWO4, resulting in higher operating voltage, power density, and Coulomb efficiency compared to CF/MFC. The use of tungsten-based semiconductors in PMFCs shows promise due to their easy synthesis, scalability, and stable photoelectrocatalytic performance.

Summary: Microbial fuel cells (MFCs) have advantages in electricity production, heavy metal removal, and energy recovery. The effects of various electron acceptors on heavy metal removal are not well understood. This study investigated the impact of different initial heavy metal concentrations, cathodic dissolved oxygen, and electrode materials on electricity generation and heavy metal removal efficiencies of Cu(II) and Cr(VI). Results showed that higher initial concentration of Cr(VI) led to a decline in voltage, coulomb efficiency, power density, and removal efficiencies of Cu(II) and Cr(VI). The use of graphite plate as the cathode electrode increased coulomb efficiency, power density, and removal efficiencies of Cu(II) and Cr(VI).

Summary: In this study, heteroatom-doped carbon nanosheets were successfully synthesized using crosslinked triazine frameworks and g-C3N4 nanosheets as a template. The nanosheets exhibited high crinkling and interconnectivity, along with a large surface area (1060 m(2) g(-1)) and pore volume (2.14 cm(3) g(-1)), with highly dispersed N, O and S. When coated on commercial Celgard separators, the modified batteries showed low self-discharge and improved rate performance, even at 4 C. Excellent cycling performances were achieved at different rates, with an initial discharge capacity of 1240 mA h g(-1) and a capacity decay of only 0.059% per cycle for over 1000 cycles at 0.5 C.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
