Summary: Efficient and low-cost Fe-doped NiS nanosheets grown on conductive carbon fiber paper were fabricated through a two-step hydrothermal process for enhanced oxygen evolution reaction (OER) performance. The Fe-NiS@CFP catalyst exhibited superior electrocatalytic activity with low internal and interface charge-transfer resistance, leading to an overpotential of 275 mV at 100 mA cm(-2) and stable performance for at least 50 hours as an OER electrode. This work provides insights into the design and fabrication of non-noble metal sulfide electrocatalysts.

Summary: Metal-encapsulated and nitrogen-doped carbon-based (M@NC) catalysts have shown excellent activity and stability in electrochemical nitrate reduction reaction (ENRR). However, their denitrification performance is unsatisfactory at high current density. In this study, a free-standing M@NCNT array on carbon cloth (CC) was synthesized to address this issue. The unique standing-up structure allows for more active centers and improves the utilization and overall performance. The Co@NCNT/CC cathode exhibited outstanding denitrification activity and stability in ENRR and showed effectiveness in removing nitrate from groundwater and coking wastewater effluent.

Summary: In this work, a facile one-step chemical bath deposition technique is employed to synthesize Fe-doped NiSe porous nanosheets on the Ni foam substrate (Fe-NiSe@NF). The synthesized Fe-NiSe@NF catalyst shows excellent water splitting performances, with overpotentials of less than 200 mV to achieve 10 mA cm(-2) for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), and maintaining stability for 35 hours. When used as both anode and cathode, the Fe-NiSe@NF catalyst achieves a current density of 10 mA cm(-2) at a low cell voltage of 1.52 V under alkaline conditions. The outstanding performances of Fe-NiSe@NF catalyst are attributed to the large electrochemical activity area of porous nanosheets, active phases generated on catalyst surfaces, and bimetallic synergistic effects. This work is significant for the development of reliable and effective electrocatalysts to promote overall water splitting.

Summary: In this study, Fe3O4 nanoparticles and graphene oxide (GO) are combined to form Fe3O4@reduced graphene oxide (rGO) composites. Cellulose nanofiber (CNF) and l-ascorbic acid are then added, and the mixture is freeze-dried to produce Fe3O4@rGO/CNF foams. The resulting foams exhibit improved electrical conductivity and magnetism, making them suitable for electromagnetic interference (EMI) shielding materials. The optimized foam shows an EMI shielding effectiveness value of approximately 23 dB in the X-band, thanks to the porous structure and composition of Fe3O4@rGO/CNF foams. This research provides a reference for the design and fabrication of novel EMI shielding materials.

Summary: We demonstrate the first simulation and experimental realization of decomposing cylindrical vector (CV) and orbital angular momentum (OAM) modes by reconstructing multi-view images of the projected intensity distribution. The use of deep learning-based stochastic parallel gradient descent (SPGD) algorithm allows for the retrieval of modal coefficients and optical field distributions with high efficiency and accuracy. The generated donut modes are experimentally decomposed into CV and OAM modes, with a purity of 99.5% for CV modes. Rapid switching of vortex modes is achieved by electrically driving the polarization controller. Our findings provide a convenient way to characterize and deepen the understanding of CV or OAM modes, with potential applications in information coding and quantum computation.

Summary: Tourmaline-LiCoO2 composites were synthesized and found to have high adsorption capacity for Pb2+. The optimal conditions for Pb2+ adsorption were determined to be 0.375 g tourmaline addition and sintering at 800 degrees C. The adsorption behavior of TM0.375LCO800 was influenced by solution pH and foreign cations, with Cu2+ and Zn2+ having the largest effect. XRD, ATR, SEM, TEM, UV-vis DRS, and XPS analysis revealed the physicochemical properties of the composites. The high-temperature transformation of tourmaline and LiCoO2 promoted Pb2+ removal. This study highlights the potential of tourmaline-LiCoO2 composites for heavy metal ion removal and provides scientific insights for future environmental applications.

Summary: Integrating filtration membrane cathode and packed granular carbon cathode in an up-flow bio-electrochemical reactor can maintain both higher-level treatment capacity and electricity generation in the microbial fuel cell (MFC). Scale-ups via unit stacking (U-S) or size-enlarged reactor/electrode (SE-RE) were tested on a Nylon wastewater, achieving high removal efficiencies of nitrogen compounds and COD, as well as significant power generation. Adjusting influent C/N with urea enhanced the COD removal and reduced membrane fouling, making U-S scale-up with urea dosage feasible for practical application in MFC treating Nylon wastewater.
