Summary: Photocatalytic ammonia synthesis technology is an effective and energy-efficient method for future nitrogen fixation. However, the weak adsorption/activation ability of N2 molecules at the photocatalyst interface hinders efficient nitrogen fixation. This study utilized MoO3-x nanowires with asymmetric defects induced by glycine to enhance the adsorption/activation capacity of N2 molecules, resulting in improved nitrogen fixation capacity at both the atomic and nanoscale levels.

Summary: On-surface synthesis (OSS) presents challenges due to the need for firm molecular anchors to prevent desorption, while maintaining sufficient lateral mobility. A strategy of locking and then unlocking molecular precursors during the reaction has been demonstrated for high-yield synthesis. This approach leads to an extended and ordered network exclusively composed of the newly synthesized macrocyclic compound, with preferential coupling achieved through steric hindrance.

Summary: The weak hydrogen adsorption and slow catalytic kinetics of MoS2 in alkaline solution hinder its performance as a catalyst for hydrogen evolution reaction (HER). This study demonstrates that carbon quantum dots (CQDs) can enhance the proton adsorption of MoS2 by establishing a suitable hydrogen adsorption gradient and promoting hydrogen spillover from CQDs to MoS2. The enhanced hydrogen spillover effect by CQDs activated MoS2 offers new possibilities for the design and preparation of efficient and low-cost catalysts.

Summary: Two-dimensional (2D) Ruddlesden-Popper (RP) layered halide perovskite with asymmetric crystal structure and spontaneous polarization generated by inserting organic cations shows excellent optoelectronic properties, and is used to fabricate 2D RP polycrystalline perovskite films and pyro-phototronic devices for temperature and light detection. The pyro-phototronic effect greatly improves the performance of the photodetectors, with higher current, responsivity, detectivity, and on/off ratio compared to the photovoltaic effect. The study also explores the influence of bias voltage, light power density, and frequency on the pyro-phototronic effect of 2D RP perovskite devices.

Summary: The use of mobile chargers in wireless rechargeable sensor networks has been extensively studied, with a focus on planning the movement of chargers. However, the potential to improve charging efficiency through energy redistribution among nodes and the broadcast nature of radio signals has been neglected. This study addresses the energy redistribution assisted charge scheduling problem in multi-charger, multi-base station WRSNs. After proving its NP-hardness, an energy loss minimization charge scheduling algorithm is proposed, which optimizes transmission energy loss using linear programming and minimizes moving energy loss using a heuristic path planning strategy. The algorithm also minimizes time span while ensuring optimal energy loss through concurrent energy transmission. Simulation results demonstrate the superiority of the proposed algorithm compared to typical algorithms.

Summary: A simple co-precipitation technique was used to synthesize MoO3 nanostructures with different surfactants. The physicochemical characterization revealed that the MoO3 nanostructures, with or without the surfactants, exhibited an orthorhombic crystalline phase. The SDS-assisted MoO3 nanoparticles showed enhanced photocatalytic activity, degrading 95.4% of Rhodamine B molecules under UV light irradiation within 140 minutes. The trapping experiment revealed that the addition of two radicals significantly influenced the photocatalytic degradation percentage, reducing it to less than 50%.

Summary: This article explores the possible neural basis of the repeated attraction to watching movies and pays tribute to Prof. Eran Zaidel, who made remarkable contributions to neuroscience and had a passion for movies. Movies, as an art form, involve the collaboration of diverse artists with specialized skills and creativity. The attention and attraction to artworks have deep biological roots. Despite extensive studies on the nature of art, the neural underpinnings of the repeated attraction to movies have been understudied. This perspective proposes clues from non-film research, suggesting the involvement of the mesolimbic reward pathway, brain regions sensitive to facial beauty, pictorial art aesthetics, and music-induced dopamine release in the repeated attraction.

Summary: This study presents the magnetic properties of MnxZn1-xFe2O4 (x = 0.5, 0.6, 0.7) nanoferrite particles prepared by sol-gel auto combustion method. The deviation of the oxygen positional parameter (U) from the ideal value of 0.375 indicates cation redistribution in the ferrite systems. The variation of bond angles suggests strengthening of A-B superexchange interaction. The ferrite nanoparticles exhibit single domain state and superparamagnetism, with increasing saturation magnetization (Ms) and decreasing coercivity (Hc) with higher Mn2+ ion concentration.

Summary: We investigate the cluster spin-glass behavior and magnetocaloric properties of potassium-ion-intercalated copper hexacyanoferrate open framework material. The structural properties are analyzed through x-ray and neutron diffraction measurements, revealing a pure single-nanocrystalline phase with face-centered cubic crystal structure. The presence of a low-spin state of FeIII and FeII is observed through Mossbauer spectroscopy, while magnetization measurements and ac susceptibility measurements confirm the ferromagnetic interaction and spin-glass behavior of the compounds, respectively. The magnetocaloric effect is found to be higher for one compound compared to the other.
