Microorganisms are the primary drivers of elemental cycles, including those involved in biogeochemical transformations of antimony (Sb) ores within contaminated mining areas. It has been reported that microorganisms can accelerate the oxidation of Sb(III) to Sb(V) compounds in mining areas. However, limited research on microbial diversity in most mining areas hampers our understanding of their potential roles in the biogeochemical cycling of Sb. This study investigated the link between the element content and the microorganism species, as well as the dispersion of the microbial community structure in Sb-contaminated areas. The results showed that the S-oxidizing bacteria presence correlated with the Sb and S distribution, and could oxidize Fe and Mn. Combined with the analysis of environmental composition, it was found that the content of Fe/Mn oxides was proportional to As and Sb oxides. The study reveals that S-oxidizing bacteria could accelerate the oxidation of Sb and As by coupling the oxidation effect of Fe/Mn in Sb-contaminated areas, thus exacerbating the As and Sb pollution. The results from the soil, sediment, and water samples show that S/Sb/As oxidizing bacteria were proportional to the content of Sb/As oxides. These results have a reference value for revealing the new insights on geochemical characteristics of elemental distributions and diversity of microbial communities and have important theoretical guidance for developing Sb pollution control and remediation technology.

For CO2 electrolysis in solid oxide electrolysis cells (SOECs), oxygen evolution reaction in the oxygen electrode limits the electrolysis process due to its slower reaction kinetics. Composite oxygen electrodes with good uniformity and interfacial connectivity are expected to promote the charge carriers' transport effectively and thus increase the electrocatalytic performance of the cell. In this work, interface engineering is applied to promote the conventional La0.6Sr0.4Co0.2Fe0.8O3−δ-Gd0.1Ce0.9O1.95 (LSCF-GDC) composite oxygen electrode to form a heterostructure via co-synthesis method. The results prove that LSCF co-synthesized with 40 wt.%GDC (LSCF/40GDC) exhibits higher conductivity and faster oxygen exchange kinetics and bulk diffusion processes. The nickel/yttria stabilized zirconia (Ni-YSZ) supported cell with LSCF/40GDC oxygen electrode could approach an impressive CO2 electrolysis current density of 2.6 A·cm−2 at 1.6 V and 800 °C. Meanwhile the cell can operate at 1.5 V and 750 °C with electrolysis current density of 1.3 A·cm−2 for more than 100 h without apparent degradation. This heterostructure enhances the interfacial bonding strength between LSCF and GDC phases, thereby providing a continuous network structure for electron and ion transport. Such an interface engineering via co-synthesis method offers a straightforward and convenient modification for oxygen electrodes, providing an alternative route for advanced materials development of CO2 electrolysis. © 2024, The Authors.

We focused on investigating the trapping characteristics of the circular Pearcey beam (CPB) on Mie particles. To study the trapping performance of CPB on particles of different sizes, we employed the generalized Lorenz-Mie theory (GLMT) for analysis. Our results revealed that the CPB exhibits a stronger optical trapping force for a larger Mie particle. To validate our findings, we constructed an experimental setup of optical tweezers and demonstrated the enhanced trapping performance of the CPB for larger Mie particles. Moreover, we discovered that, compared to the conventional circular Airy beam with the same focusing length, CPB also presents a significantly better trapping performance. Finally, by adjusting the spatial distribution factor of the CPB, we can effectively control the trapping performance in optical manipulation. The relationship between the trapping force properties of the CPB and the spatial distribution factor can be formulated as an exponential function. Overall, our study provides valuable insights into the optical trapping potential of autofocusing beams, particularly the CPB. These findings open up different avenues for the development of photonic tools in the field of optical trapping and manipulation.

Desalination and purification of seawater and wastewater has been considered as an effective strategy to alleviate water shortage. Interfacial solar steam generation utilizing biomass materials as the core of the evaporator has drawn considerable awareness of its distinctive natural structure. Herein, we report a biomass solar evaporator composed of a convenient and reinforced water transport device using carbonized Pleurotus eryngii (C-PE). Benefiting from the microporous carbon skeleton and microchannels, the as-prepared device exhibits excellent water transpiration and rapid evaporation. The hierarchically porous structure of C-PE could entice interior multiple light reflection to enable all-directional light absorption (> 91.7%) and enhance the capability of photothermal conversion. This device shows a high evaporation rate of 1.22 kg m-2 h-1 under 1 kW m-2 power density. Moreover, the high efficiencies of 81.7% under 1 kW m-2 and 95.1% under 4 kW m-2 for C-PE evaporator were attained. Furthermore, using C-PE for extraction of potable condensed water from wastewater samples containing Na+ , heavy metal ions, dyes, and oil shows a promising potential in terms of cost and sewage treatment. The multiple advantages of high evaporation efficiency and wastewater purification endow the C-PE evaporator available for future bio-derived solar-thermal materials and desalination applications. © 2022, The Authors.

The environmental-friendly recycling of rare earth and transition metals in spent Ni-MH batteries has attracted extensive attention. Herein, we demonstrate a sustainable strategy for all-metal recovery from spent Ni-MH batteries based on the electrolysis of Na2SO4 solution. The eletrolyzed H2SO4 solution (0.82 mol L-1) served as the leaching agent for the electrode materials of spent Ni-MH batteries, and the NaOH solution (0.87 mol L-1) was used to neutralize the leaching solution and to produce metal hydroxide products, in which process Na2SO4 was regenerated. The electrode materials were successfully dissolved by the electrolyzed H2SO4 with addition of hydrogen peroxide, and more than 99% of the rare earths were firstly precipitated at pH 1.0 in form of double sulfphate precipitation, which were converted to hydroxides by reacting with NaOH. In the following purification steps, Al3+ and Fe3+ were deposited at pH 5.5, and Zn2+ and Mn2+ were extracted by saponified D2EHPA-kerosene from the leaching solution, led to two hydroxide byproducts with considerable economic value. Ni2+ and Co2+ were precipitated at pH 9.5 with a total recovery rate of 97.5%, resulted in cobalt and nickel hydroxides with high purity. The overall recycled Na2SO4 in the process was up to 97%. The closed-loop process brings with minimal environmental impact and maximal output, which is also expected to make a considerable profit in recycling spent Ni-MH batteries. © 2022, The Authors.

The study focused on the preparation of spongy polyether sulfone (PES) ultrafiltration membranes and investigated the effects of N-vinylpyrrolidone (NVP) and air exposure on membrane properties. NVP was used as a pore-forming additive to create interconnected pores in the membrane structure, leading to higher water permeability. The influence of NVP and air exposure time on various membrane characteristics such as morphology, pore size, porosity, permeability, and selectivity were examined. Furthermore, longer air exposure times generally improved membrane porosity and performance. However, excessive exposure led to membrane shrinkage and reduced mechanical strength. Therefore, an optimized membrane, referred to as M4, was identified based on its superior water flux, rejection rate and anti-pollution performance. The water flux of the M4 membrane reached 797.62±21.02 L/m2·h, which was 1.9 times higher than that of a pure PES membrane. Additionally, the rejection rate of bovine serum albumin (BSA) increased from 57.97±0.15% to 95.89±0.08% compared to the pure PES membrane. This indicates that the incorporation of NVP and air exposure effectively mitigates the trade-off effect between permeability and selectivity. These spongy PES ultrafiltration membranes exhibited desirable properties for protein separation and wastewater treatment, making them promising materials for various applications in the field. © 2024, The Authors.
