Summary: The study found that Quantum Griffiths singularity (QGS) exists in ultrathin PdTe2 films, with QGS observed under both perpendicular and parallel magnetic fields in four-monolayer films. However, as the film thickness increases to six monolayers, QGS disappears under perpendicular field but persists under parallel field, suggesting differences in microscopic processes may be the cause of this discrepancy. This work demonstrates the universality of parallel field induced QGS and calls for further investigation on quantum phase transitions under parallel magnetic fields.

Summary: In this paper, a monolayer of TiX2 (X = S, Se) is utilized to suppress the shuttle effect of polysulfides, thus accelerating the kinetic process of lower-order polysulfides. The adsorption energies of TiX2 for Na2Sn are better than those of common electrolytes, and the adsorption has negligible effect on the structure of Na2Sn. The anchoring behavior of TiX2 to Na2Sn does not affect the metallic properties of pristine TiX2, but it can effectively reduce the diffusion barrier energy of Na2S and improve the utilization rate of sulfur.

Summary: The researchers used scanning tunneling microscopy and spectroscopy to study the evolution of electronic structures at the interface of a phase-engineered monolayer NbSe2 heterostructure. They observed the penetration of the metallic state H-NbSe2 into the Mott insulating state T-NbSe2, with a prominent CDW proximity effect, and detected an insulating Mott gap collapse at the electronic phase transition region. Theoretical calculations suggested that this collapse could be attributed to electron doping induced by the interface, providing insights into controlling Mott insulating states through phase engineering.

Summary: In this study, the real-time dynamics of N-2 dissociation on graphene sheets under femtosecond laser irradiation were investigated using time-dependent density functional theory. It was found that electrons generated by plasmon excitation of graphene transfer to the N-2 molecular antibonding orbital and activate the N-N bond. The threshold of laser intensity of N-2 dissociation can be effectively reduced by mixing CO molecules. This work provides fundamental insights into the plasmon induced N-2 activation process at the atomic scale and demonstrates graphene as a promising candidate material for N-2 reduction photocatalysts with excellent performance.

Summary: The study investigated the performance of 2,5-dichloronitrobenzene in UV/sulfite advanced reduction processes (ARPs) in terms of reaction rate, inhibition mechanisms, and degradation pathways. The results showed that the reaction rate of 2,5-dichloronitrobenzene increased with increasing sulfite dosage and pH value. Hydrated electron was found to play a dominant role in the UV/sulfite ARPs. A new sulfite activating pathway and the inhibitions of Cl- and NO3- were discovered. The reduction pathways of 2,5-dichloronitrobenzene and its final product were also predicted.

Summary: In this work, Cu-incorporated ZnO electrocatalyst (Cu25Zn-A) was synthesized on a Zn plate for electrochemical CO2 reduction reaction (e-CO2RR). The Cu25Zn-A exhibited a high CO Faraday efficiency (>90%) and a CO yield rate of 0.49 mmol cm-2 h-1. The enhanced catalytic activity of Cu25Zn-A was attributed to the presence of Cu steps on the reconstructed surface, which weakened the adsorption of OH-/CO32- and enhanced the adsorption/activation of reactants and stabilization of intermediates. Furthermore, Cu incorporation increased the density of defects in Zn oxide, resulting in improved deoxygenation step. These findings provide valuable insights into the mechanism of CO2 reduction and can guide the design of novel electrocatalysts.

Summary: This study used Japanese encephalitis incidence data in Guangxi Province, China from 2004 to 2010 to examine the driving forces and interactive effects of environmental and social factors on the disease. The findings revealed a fluctuating downward trend in Japanese encephalitis incidence during the study period, with the disease being seasonal and concentrated in northwestern Guangxi. Factors such as high temperatures, slope, vegetation, GDP of tertiary industries, GDP of primary industries, and number of pigs slaughtered contributed significantly to the occurrence of Japanese encephalitis. This study highlights the importance of understanding the combined effects of social and environmental factors in controlling and preventing the transmission of Japanese encephalitis.

Summary: The electrocatalytic reduction of nitrate to ammonia offers a new way to generate ammonia from waste water, but the competition between nitrate conversion and hydrogen evolution reaction (HER) limits its development. This study synthesized MoS2 with sulfur vacancies (SVs) and used these SVs to promote the production of ammonia. MoS2 with SVs showed higher ammonia synthesis performance and faradaic efficiency. The research enhances our understanding of how to handle the content of MoS2 with SVs when preparing monolayered MoS2 with special catalytic properties.

Summary: This study reveals that surface evolution plays a crucial role in enhancing the electrocatalytic performance of transition metal oxides for electrochemical nitrate reduction reaction (e-NO3RR). Incorporating nickel into Co3O4 can promote surface reconstruction and improve the adsorption of intermediates and reduce energy barriers, leading to enhanced catalytic performance. The reconstructed cobalt-nickel hydroxides (CoyNi1_y(OH)2) on the catalyst's surface serve as the active phase.

Summary: The study clarified the path of the temporal branch of facial nerve (TB) as it crosses the zygomatic arch (ZA) through anatomical dissection and observation on plastinated slices. The TB was found to cross the ZA in three types: type I (21.8%), type II (50.0%), and type III (28.1%) twigs. The average distances between the anterior and posterior trunks of TB and the anterior part of the auricle at the superior and inferior edges of the ZA were measured. The study also highlighted the recommended avoidance of this area during clinical operations to prevent TB injury.

Summary: In this study, a simply-prepared and highly sensitive electric field-induced surface-enhanced Raman spectroscopy (E-SERS) substrate is proposed by combining a pyroelectric material (PMN-PT) with plasmonic silver nanoparticles (Ag NP). The SERS signals are significantly enhanced by more than 100 times after applying positive or negative pyroelectric potentials, mainly due to the chemical mechanism induced by charge transfer. Additionally, a novel nanocavity structure composed of PMN-PT/Ag/Al2O3/silver nanocubes (Ag NCs) is introduced, which can efficiently convert light energy into heat energy and achieve a tremendous enhancement of SERS signals.
