Minimizing disorder and defects is crucial for realizing the full potential of two-dimensional transition metal dichalcogenides(TMDs) materials and improving device performance to desired properties. However, the methods in defect controlcurrently face challenges with overly large operational areas and a lack of precision in targeting specific defects. Therefore,we propose a new method for the precise and universal defect healing of TMD materials, integrating real-time imaging withscanning transmission electron microscopy (STEM). This method employs electron beam irradiation to stimulate the diffusionmigration of surface-adsorbed adatoms on TMD materials grown by low-temperature molecular beam epitaxy (MBE),and heal defects within the diffusion range. This approach covers defect repairs ranging from zero-dimensional vacancydefects to two-dimensional grain orientation alignment, demonstrating its universality in terms of the types of samples anddefects. These findings offer insights into the use of atomic-level focused electron beams at appropriate voltages in STEMfor defect healing, providing valuable experience for achieving atomic-level precise fabrication of TMD materials.

Dear Editor,As mass vaccination has been accomplished worldwide and a growing number of individuals have already been infected by SARS-CoV-2,understanding the incidence of subsequent re-infection is urgently required for comprehending the transmission dynamics of COVID-19(Bobrovitz et al.,2023).Additionally,current SARS-CoV-2 variants cause widespread escape from the neutralizing antibody(nAb)elicited by current ***,durable neutralization and memory B cell responses can be predicted by rapid CD4t T cell responses,particularly strong circulating T follicular helper(cTfh)cell responses,in individuals infected with SARS-CoV-2(Gong et al.,2020;Boppana et al.,2021;Narowski et al.,2022).Although nAb titers are known as predictors of protection against SARS-CoV-2 variants(Khoury et al.,2021),identifying more potential factors that could predict the risk of re-infection following primary infection and vaccination has become quite important in shaping prevention strategies(Chemaitelly et al.,2023).

Exceptional Performance of 3D Additive Manufactured NiFe Phosphite Oxyhydroxide Hollow Tubular Lattice Plastic Electrode for Large-Current-Density water Oxidization

作者： Ding, liping zhang, lin li, Gaoyuan Chen, Shuyan Yan, Han Tu, Haibiao Su, Jianmin li, Qi Tang, Yanfeng wang, Yanqing Nantong Univ Sch Chem & Chem Engn Nantong 226007 Peoples R China

In this article, we report a 3D NiFe phosphite oxyhydroxide plastic electrode using high-resolution digital light processing (DLP) 3D-printing technology via induced chemical deposition method. The as-prepared 3D plastic electrode exhibits no template requirement, freedom design, low-cost, robust, anticorrosion, lightweight, and micro-nano porous characteristics. It can be drawn to the conclusion that highly oriented open-porous 3D geometry structure will be beneficial for improving surface catalytic active area, wetting performance, and reaction-diffusion dynamics of plastic electrodes for oxygen evolution reaction (OER) catalysis process. Density functional theory (DFT) calculation interprets the origin of high activity of NiFe(PO3)O(OH) and demonstrates that the implantation of the -PO3 can effectively bind the 3d orbital of Ni in NiFe(PO3)O(OH), lead to the weak adsorption of intermediate, make electron more active to improve the conductivity, thereby lowing the transform free energy of *O to *OOH. The water oxidization performance of as-prepared 3D NiFe(PO3)O(OH) hollow tubular (HT) lattice plastic electrode has almost reached the state-of-the-art level compared with the as-reported large-current-density catalysts or 3D additive manufactured plastic/metal-based electrodes, especially for high current OER electrodes. This work breaks through the bottleneck that plagues the performance improvement of low-cost high-current electrodes.

Hollow semiconductor nanostructures with direct z-scheme heterojunction have significant advantages for photocatalytic reactions,and optimizing the interfacial charge transmission of z-scheme heterojunction is the hinge to achieve excellent solar conversion *** this work,tubular Ni_(1−x)Co_(x)S_(2)-CdS heterostructures with reinforced z-scheme charge transmission were constructed through an In-metal-organic framework(MOF)templated *** z-scheme charge transfer mechanism was sufficiently confirmed by combining density functional theory(DFT)calculation,X-ray photoelectron spectroscopy(XPS),surface photovoltage spectroscopy(SPV),and radical testing ***,the use of sodium citrate complexant contributes to the formation of intimate heterointerface,and the Fermi level gap between CdS and NiS_(2)is enlarged through Co doping into NiS_(2),which enhances the built-in electric field and photo-carriers transmission driving force for Ni_(1−x)Co_(x)S_(2)-CdS heterojunction,resulting in an evidently promoted activity toward H2 evolution reaction(HER).Under visible-light(λ>400 nm)irradiation,the Ni_(1−x)Co_(x)S_(2)-CdS composite with 10 mol%Co doping and 80 wt.%CdS(NC_(0.10)S-80%CdS)achieved an outstanding HER rate up to 35.94 mmol·g^(−1)·h^(−1)(corresponding to the apparent quantum efficiency of 34.7%at 420 nm),approximately 76.4 times that of 3 wt.%Pt-loaded CdS and it is much superior to that of most CdS-based photocatalysts ever ***,the good photocatalytic durability of Ni_(1−x)Co_(x)S_(2)-CdS heterostructures was validated by cycling and long-term HER *** work could inspire the development of high-performance z-scheme heterojunction via optimizing the morphology and interfacial charge transmission.

Fluid intelligence is a cognitive domain that encompasses general reasoning, pattern recognition, and problem-solving abilities independent of task-specific experience. Understanding its genetic and neural underpinnings is critical yet challenging for predicting human development, lifelong health, and well-being. One approach to address this challenge is to map the network of correlations between intelligence and other constructs. In the current study, we performed a genome-wide association study using fluid intelligence quotient scores from the UK Biobank to explore the genetic architecture of the associations between obesity risk and fluid intelligence. Our results revealed novel common genetic loci (SH2B1, TUFM, ATP2A1, and FOXO3) underlying the association between fluid intelligence and body metabolism. Surprisingly, we demonstrated that SH2B1 variation influenced fluid intelligence independently of its effects on metabolism but partially mediated its association with bilateral hippocampal volume. Consistently, selective genetic ablation of Sh2b1 in the mouse hippocampus, particularly in inhibitory neurons, but not in excitatory neurons, significantly impaired working memory, short-term novel object recognition memory, and behavioral flexibility, but not spatial learning and memory, mirroring the human intellectual performance. Single-cell genetic profiling of Sh2B1-regulated molecular pathways revealed that Sh2b1 deletion resulted in aberrantly enhanced extracellular signal-regulated kinase (ERK) signaling, whereas pharmacological inhibition of ERK signaling reversed the associated behavioral impairment. Our cross-species study thus provides unprecedented insight into the role of SH2B1 in fluid intelligence and has implications for understanding the genetic and neural underpinnings of lifelong mental health and well-being.
