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: This study presents an IrPd electrocatalyst supported on ketjenblack that exhibits outstanding bifunctional performance for both HER and OER at wide pH conditions. The optimized IrPd catalyst shows specific activity of 4.46 and 3.98 A mg(Ir)(-1) in the overpotential of 100 and 370 mV for HER and OER, respectively, in alkaline conditions. When applied to the anion exchange membrane electrolyzer, the Ir44Pd56/KB catalyst demonstrates promising prospects for practical applications with stability of >20 h at a current of 250 mA cm(-2) for water decomposition. This work not only offers an advanced electrocatalyst, but also provides guidance for the rational design of desirable bifunctional electrocatalysts for HER and OER by regulating the microenvironments and electronic structures of metal catalytic sites for diverse catalysis.

Summary: This study reports rechargeable aqueous batteries based on ammonium-ions, which have great potential in low-cost energy storage systems due to their superior characteristics. However, the development is challenged by the lack of cathode materials that can meet the requirements for high capacity and stable working voltage simultaneously. The researchers discovered NH4+ storage behavior in a MnAl layered double hydroxide (LDH) series and observed stable working voltage and high discharge capacity in an optimized LDH sample. Assembling the complete battery with a 3,4,9,10-perylenetetracarboxylic diimide anode resulted in a high energy density, outperforming most recently reported counterparts. The study also revealed the rapid amorphization conversion of the LDH cathode during the first charge process, which facilitates NH4+ isotropic transport and provides new insights into electrode design for aqueous batteries.

Summary: The study on stability criterion and interaction analysis for grid-connected inverters under weak grid conditions is highly valuable. This paper proposes a control loop stability criterion based on controller bandwidth overlap, which allows for independent analysis of each loop as well as overall system stability. By analyzing the interaction among the grid impedance, phase-locked loop, and current controller, the proposed criterion provides a deeper understanding of system stability under weak grid conditions. Simulation and experimental results validate the accuracy of the proposed stability criterion and interaction analysis.

Summary: In this study, we developed a method to prepare porous polymer particles with controllable surface textures. By combining emulsion interfacial instabilities and phase separation, we dissolved the oil phase of the emulsion containing the polymer, a cosurfactant, and a nonvolatile oil into a volatile good solvent. The evaporation of the good solvent triggered interfacial instability and phase separation, resulting in the formation of porous polymer particles with surface roughness. Varying the concentrations of the cosurfactant and nonsolvent allowed for the tuning of surface textures and internal pore structures. Porous polymer particles with surface roughness have potential applications in enzyme carriers, isolation and purification, superhydrophobic coatings, drug delivery, etc.

Summary: The non-metal NH4+ carrier is attracting a lot of interest for aqueous energy storage due to its light molar mass and fast diffusion in aqueous electrolytes. Previous studies suggested that NH4+ ion storage in layered VOPO4 center dot 2H2O was impossible due to a phase change caused by the removal of NH4+ from NH4VOPO4. However, this belief has been updated and highly reversible intercalation/de-intercalation behavior of NH4+ in layered VOPO4 center dot 2H2O has been demonstrated. The results provide new insight into the intercalation/deintercalation of NH4+ ions in layered hydrated phosphates through crystal water enhancement effect.

Summary: Session-based recommendation uses click history to recommend the next click. Although GNN-based models show promising results, there are still limitations: ignoring item order, limited capturing of long-term dependencies, and interference from noise items in the session embedding. To address these issues, we propose MPER, which introduces learnable position embedding, SLD-encoder, adaptive sparse target attention, and a linear integration layer. Experimental results on three datasets demonstrate the superiority of MPER over SOTA baselines.

Summary: In this study, a novel composite of bacterial cellulose (BC) and expanded vermiculite (EVMT) was used as an adsorbent for dyes and antibiotics removal. The BC/EVMT composite exhibited a microporous structure, providing abundant adsorption sites. The adsorption capacity of BC/EVMT for methylene blue (MB) increased with increasing pH, while the adsorption capacity for sulfanilamide (SA) decreased. The Langmuir isotherm model and pseudo-second-order kinetic model were found to fit the adsorption of MB and SA well on the BC/EVMT composite. The BC/EVMT composite showed high adsorption capacities for both MB and SA, making it a promising adsorbent for wastewater treatment.

Summary: Macleaya cordata, a dominant plant in mine tailings, has been found to accumulate high levels of zinc (Zn) and has high tolerance to Zn. Comparative analysis of transcriptomes and proteomes of M. cordata leaves treated with 200 μmol•L-1 of Zn for 1 or 7 days revealed significant upregulation of iron (Fe)-deficiency-related genes and proteins, which are believed to be involved in the transport and tolerance of Zn in M. cordata leaves.

Summary: Psychological pain influences purchase decisions, particularly for products with different prices, and the neural mechanism behind it is not well known. This study used EEG to record participants' decision-making process of buying high-price vs. low-price products after experiencing pain or no pain. The results showed that participants who experienced pain had a lower purchase rate for low-price products. EEG and time-frequency analysis results revealed that pain affected late positive potential (LPP) and beta activities, indicating that psychological pain influences purchase decision processing by reducing attention resources and initiating behavioral inhibition. This study expands our understanding of the relationship between pain and purchase behaviors by examining different pain effects in low- and high-price purchase contexts.
