Summary: The development of a green and environmentally friendly cyanide-free gold plating bath with hypophosphite as a reducing agent has successfully retarded the corrosion of the Ni-P layer. The obtained Cu/Ni-P/Au coatings showed significantly improved corrosion resistance performance, with stable baths and no turbidity detected for 210 days, reflecting good stability. This cyanide-free electroless gold deposition process holds potential research value and application prospects in the microelectronic industry.

Summary: In this study, phytosynthesized iron nanoparticles were used to effectively remove Sb(III) and Sb(V) from mining wastewater. The nanoparticles oxidized Sb(III) to Sb(V) on their surface, and both Sb species were adsorbed onto the nanoparticles. The adsorption behavior of Sb(III) and Sb(V) followed the Langmuir adsorption model and pseudo-second-order kinetics. The nanoparticles showed great potential for removing Sb from contaminated mining wastewaters.

Summary: This study prepared a novel Fe-Ti-chitosan composite (FTC-2/1) via a facile coprecipitation method for efficient elimination of Sb(III) and Sb(V) in water. The FTC-2/1 exhibited abundant surface hydroxyl groups and a unique three-dimensional porous structure, promoting the diffusion kinetics of Sb(III) and Sb(V). Density functional theory calculations revealed that the highest adsorption efficiency of FTC-2/1 was attributed to the preferential adsorption of the Fe-Ti bidentate complex towards Sb(III) and Sb(V) and the electronic structure reconstruction of the adsorbed antimony molecules and Fe-Ti atoms.

Summary: Gold electrodeposition from a thiosulfate solution was used to bridge parallel electrodes with insulator layer thickness, and the observation of conductance quantization phenomena was attributed to the formation of atomic point contacts. Addition of sulfite to the electrolyte resulted in smoother current increases, and nanogap morphology could be controlled by applied bias, with lower bias producing smoother nanogap edges. Electrochemical cycling was shown to be effective in tuning nanogap structure.

Summary: The study demonstrates that doping with vanadium can effectively modify the band structure in magnetic topological insulators, leading to the enhancement of SdH oscillations and the induction of long-range ferromagnetic order. The angle-dependent SdH oscillations reveal their 2D nature and their connection to topological surface states. This tunability by doping and the coexistence of surface states with ferromagnetism highlight the potential of Sb2-xVxTe3 thin films in energy band engineering for quantum electronics and spintronics design.

Summary: The study demonstrated the successful removal of trace levels of Sb(V) from mining wastewater using ZIF-8, a specific type of Metal Organic Frameworks (MOFs). The adsorption process followed the Langmuir adsorption isotherm with pseudo second-order kinetics, and ZIF-8 remained structurally stable even after repeated use. The proposed removal mechanism involved complexation of zinc with Sb(V) on ZIF-8, showing potential for practical removal of antimony pollution in mining wastewaters.

Summary: In this study, the microbial communities in two coastal areas near the estuaries of the LH River and YLJ River in the Northwestern Pacific Ocean were investigated. Geographical segregation and significant environmental heterogeneity were observed between these two areas due to the existence of the Liaodong Peninsula and different levels of urbanization. There were significantly different regional species pools and biogeographic patterns for both bacterial and protistan communities between LH and YLJ coastal areas. The dominant drivers of differences in bacterial and protistan communities between the LH and YLJ coastal areas were variation in regional species pools and species turnover. Local community assembly mechanisms, including heterogeneous selection and dispersal limitation, played important roles in shaping the bacterial and protistan communities in a single-studied area.

Summary: In this study, the reductive processes and mechanisms of Se(IV) and Te(IV) were investigated using a marine bacterium Shewanella sp. CNZ-1. The results showed that CNZ-1 can effectively reduce Se(IV) and Te(IV) under saline conditions. The reduction of Se(IV) was enzyme-based, while the reduction of Te(IV) was more like a detoxification process. These findings expanded our understanding of the fate of Se(IV) and Te(IV) in the saline environment and provided guidance for pollution control.

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. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

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.
