摘要：
Phosphorization of molybdates has been shown to promote hydrogen evolution reaction (HER) activity but is usually detrimental to oxygen evolution reaction (OER) activity, frustrating efforts to create bifunctional HER/OER electrocatalysts. Herein, we show that Fe2O3-modulated P-doped CoMoO4 on nickel foam (Fe-P-CMO) is an excellent bifunctional HER/OER electrocatalyst in alkaline media, with the adverse effect of phosphorization on the OER activity of CoMoO4 being countered via Fe2O3 introduction. An alkaline splitting electrolyser assembled directly using the self-supporting Fe-P-CMO electrode possessed outstanding long-term durability with ultralow cell voltages of 1.48 and 1.59 V required to achieve current densities of 10 and 100 mA cm−2, respectively. Detailed experimental investigations showed that during HER, P-doped CoMoO4 in Fe-P-CMO underwent surface reconstruction with the in-situ formation of Co(OH)2 on the P-CoMoO4 (Co(OH)2/P-CoMoO4). During OER, P-doped CoMoO4 was deeply reconstructed to CoOOH with the complete dissolution of Mo, leading to the in-situ formation of Fe2O3/CoOOH heterojunctions.

摘要：
Synthetic lethality is a phenomenon wherein the simultaneous deficiency of two or more genes results in cell death, while the deficiency of any individual gene does not lead to cell death. In recent years, synthetic lethality has emerged as a significant topic in the field of targeted cancer therapy, with certain drugs based on this concept exhibiting promising outcomes in clinical trials. Nevertheless, the presence of tumor heterogeneity and the intricate DNA repair mechanisms pose challenges to the effective implementation of synthetic lethality. This review aims to explore the concepts, development, and ethical quandaries surrounding synthetic lethality. Additionally, it will provide an in-depth analysis of the clinical application and underlying mechanism of synthetic lethality.

摘要：
The need for low-carbon solar electricity production has become increasingly urgent for energy security and climate change mitigation. However, the bandgap and carrier separation critical requirements of high-efficiency solar cells are difficult to satisfy simultaneously in a single material. In this work, several van der Waals ZnIn(2)X(4) (X = S, Se, and Te) heterostructures were designed based on density functional theory. Our results suggest that both ZnIn(2)S(4)/ZnIn(2)Se(4) and ZnIn(2)Se(4)/ZnIn(2)Te(4) heterostructures are direct bandgap semiconductors at the Γ point. Besides, obvious carrier spatial separations were observed in the ZnIn(2)S(4)/ZnIn(2)Se(4) and ZnIn(2)Se(4)/ZnIn(2)Te(4) heterostructures. Interestingly, the ZnIn(2)S(4)/ZnIn(2)Se(4) heterostructure has a suitable bandgap of 1.43 eV with good optical absorption in the visible light range. The calculated maximum theoretical photoelectric conversion efficiency of ZnIn(2)S(4)/ZnIn(2)Se(4) heterostructure was 32.1%, and it can be further enhanced to 32.9% under 2% tensile strain. Compared to single-layer ZnIn(2)X(4) materials, the electron effective mass of the ZnIn(2)S(4)/ZnIn(2)Se(4) heterostructure is relatively low, which results in high electron mobility in the heterostructure. The suitable bandgap, obvious carrier separation, high electron mobility, and excellent theoretical photoelectric conversion efficiency of the ZnIn(2)S(4)/ZnIn(2)Se(4) heterostructure make it a promising candidate for novel 2D-based photoelectronic devices and solar cells.

Direct Synthesis of Phosphoryltriacetates from White Phosphorus via Visible Light Catalysis: The reaction of P4 with α‐bromo esters using fac‐Ir(ppy)3 as the photocatalyst and blue LEDs (456 nm) as the light source was developed for the first time to afford a series of phosphoryltriacetates. This approach features mild reaction conditions and simple operational process without chlorination. Abstract Organophosphorus compounds (OPCs) are widely used in many fields. However, traditional synthetic routes in the industry usually involve multistep and hazardous procedures. Therefore, it's of great significance to construct such compounds in an environmentally‐friendly and facile way. Herein, a photoredox catalytic method has been developed to construct novel phosphoryltriacetates. Using fac‐Ir(ppy)3 (ppy=2‐phenylpyridine) as the photocatalyst and blue LEDs (456 nm) as the light source, white phosphorus can react with α‐bromo esters smoothly to generate phosphoryltriacetates in moderate to good yields. This one‐step approach features mild reaction conditions and simple operational process without chlorination.

摘要：
Magnetic skyrmions can be generated, destroyed and driven to motion by electric spin currents in metals based on the spin transfer torque (STT) mechanism. However, the STT technique does not work in insulating materials because no electric currents can pass through. Fortunately, the magnetoelectric (ME) interaction that is present in multiferroic insulators makes it possible to manipulate magnetic skyrmions by applying electric fields. We have recently simulated ferroelectric (FE) skyrmionic crystals (or skyrmionic lattices so that skyrmionic crystals can be abbreviated as SkLs) formed in two-dimensional (2D) ferromagnetic (FM) multiferroic materials. Antiferromagnets are more abundant in nature. For this reason, we employ here a quantum computational method which we have developed in recent years to investigate the magnetic and polarized electric dipole textures of a 2D antiferromagnetic (AM) multiferroic system. Consequently, we observe in simulations that antiferroelectric (AE) and AM skyrmionic crystals can be generated simultaneously in a broad temperature and magnetic field phase region. Each of these AM and AE SkLs can be decomposed into two ferromagnetic or ferroelectric lattices which are FM or FE SkLs respectively, an FE skyrmion in one FE SkL is an electric dipole complex formed around the interstitial site of another FE SkL. The topological charges of the FE skyrmions are quantized to be integers, half integers or the odd multiples of ±0.25 especially within subsequently normally applied electric fields. In a strong external magnetic field, AE SkL and AM vortical crystal (VL) usually coexist. A subsequently applied perpendicular electric field is able to stabilize or destroy the both sorts of SkLs, and considerably elevate the coexisting temperatures of the AE SkL and AM VL textures even the electric field is very weak.
摘要：
Carbon nitride quantum dots (CNQDs) modified cobalt phosphate (CoPi) composites CNQDs/CoPi‐x were applied in photocatalytic H2 evolution. It shown enhanced activity and stability compared to pure CoPi using Eosin Y (EY) as a sensitizer. The employment of CNQDs boosted electron transfer from radical EY·− to CNQDs/CoPi‐x. Abstract In the present work, carbon nitride quantum dots (CNQDs)‐modified cobalt phosphate (CoPi) composites CNQDs/CoPi‐x (x = 1, 2, 3) were prepared at room temperature and characterized by FTIR, XRD, UV–Vis DRS, EIS, SEM, TEM/HR‐TEM, XPS, and N2 gas adsorption. The morphologies and surface areas of CNQDs/CoPi‐x have no remarkable change after modification of CNQDs, compared with pure CoPi. The obtained CNQDs/CoPi‐x shows enhanced activity and stability of photocatalytic H2 evolution compared to pure CoPi using Eosin Y (EY) as a sensitizer and triethanolamine as an electron donor. The CNQDs/CoPi‐2 possesses the highest hydrogen evolution rate, 234.5 μmol h−1 g−1, upon visible light, which outshines that of CoPi by 2.4 times. It was believed that the enhanced photocatalytic performances of the CNQDs/CoPi‐2 could result from the boosted electron transfer from radical EY·− to CNQDs/CoPi‐2 by the employment of CNQDs; in addition, the visible‐light activity of CNQDs contributes to hydrogen evolution. The mechanism of photocatalytic hydrogen production was discussed. This study may contribute toward the development of production of “green hydrogen” using solar.

Antimony and arsenic contamination;Soil washing;Agricultural soil;Bioavailability
摘要：
Antimony (Sb) and arsenic (As) contamination in agricultural soil poses human health risks through agricultural products. Soil washing with degradable low molecular weight organic acids (LMWOAs) is an eco-friendly strategy to remediate agricultural soils. In this study, three eco-friendly LMWOAs, oxalic acid (OA), tartaric acid (TA), and citric acid (CA), were used to treat Sb and As co-contaminated agricultural soil from Xikuangshan mine area. The OA, TA, and CA washed out 18.4, 16.8, and 26.6% of Sb and 15.3, 19.9, and 23.8% of As from the agricultural soil, with CA being the most efficient reagent for the soil washing. These organic acids also led to pH decline and macronutrients losses. Fraction analysis using a sequential extraction procedure showed that the three organic acids targeted and decreased the specifically sorbed (F2) (by 19.3-37.6% and 2.41-23.5%), amorphous iron oxide associated (F3) (by 49.1-61.2% and 51.2-70.2%), and crystallized iron oxide associated (F4) (by 12.3-26.0% and 26.1-29.1%) Sb and As. The leachability of Sb and As, as well as their concentrations and bioconcentration factor (BCF) in vegetables reduced due to the soil washing. It demonstrated that the bioavailability of both the elements was decreased by the organic acids washing. The concentrations of Sb and As in typical vegetable species cultivated in CA washed soil were less than the threshold value for consumption safety, while those in OA and TA washed soils were still higher than the value, suggesting that only CA is a potential washing reagent in soil washing for Sb- and As-contaminated agricultural soil.
摘要：
Developing high-efficiency electrocatalysts for the oxygen evolution reaction (OER) remains a crucial bottleneck on the way to the water splitting for producing clean fuel (H2). Compared with single atom catalysis (SACs), dualatom catalysts (DACs) have attracted great interest due to higher OER catalytic efficiency. In this work, the OER properties of dual-metal-N4 embedding armchair single-walled carbon nanotubes (D-MN4/CNTs) were systematic studied by density functional theory (DFT) simulations. Our results indicate that CoN4 embedding armchair CNTs exhibit higher OER activity than the corresponding planar structure, especially for CoN4 embedding in armchair CNT (4, 4) (CNT4). For MN4-CoN4 co-embedding CNTs, the TiN4-CoN4/CNTs have good OER synergistic effect with the lowest overpotential. Besides, the diameter of CNTs have a significant impact on the OER efficiency. The lowest reaction overpotential 0.47 V were obtained in TiN4-CoN4/CNT4 with a 5.69 angstrom tube diameter. Interestingly, compressive stress will further enhance the synergistic effect between two metal atoms in the OER reaction. The OER overpotential of CoN4-TiN4 embedding armchair CNT4 can reduce to 0.40 V under the -4 % uniaxial compression strain. These works were expected to better understand the synergistic mechanisms and design high-efficiency dual-atom OER electrocatalysts.

摘要：
This study aimed to explore the effectiveness of school-based mindfulness training on learning burnout of Chinese middle school students and the mediating role of psychological resilience between dispositional mindfulness and learning burnout. A cluster randomized controlled trial was conducted with repeated measurement analysis, in which 62 Chinese middle school students in the experimental group received a 10-week school-based mindfulness training. In comparison, 63 students in the control group were randomized to receive no intervention. Learning burnout, dispositional mindfulness, and psychological resilience were measured by Adolescent Student Burnout Inventory, Five Facet Mindfulness Questionnaire, and Resilience Scale for Chinese Adolescents, respectively. The results showed: (1) Compared with the experimental group's pre-test scores and the control group's pretest and posttest scores, the posttest scores of learning burnout in the experimental group significantly decreased. In contrast, the posttest scores of dispositional mindfulness and psychological resilience in the experimental group significantly increased. Meanwhile, the control group gained no significant changes between the pre-and posttest in learning burnout, dispositional mindfulness, and psychological resilience. (2) Dispositional mindfulness was positively related to psychological resilience, while dispositional mindfulness and psychological resilience were negatively associated with learning burnout. (3) The direct effect of dispositional mindfulness on learning burnout and the mediating effect of psychological resilience between dispositional mindfulness and learning burnout were significant. This study suggested that school-based mindfulness training distinctly improves dispositional mindfulness and psychological resilience and alleviates learning burnout in Chinese middle school students. Furthermore, psychological resilience plays a mediating role between dispositional mindfulness and learning burnout.
School-based mindfulness training is an effective intervention method to alleviate learning burnout of Chinese middle school students.
Dispositional mindfulness is a protective factor of learning burnout, and psychological resilience plays a mediating role between dispositional mindfulness and learning burnout.
School-based mindfulness training alleviates learning burnout by improving dispositional mindfulness and psychological resilience.

摘要：
Semiconductor planar nanowire arrays (PNAs) are essential for achieving large-scale device integration. Direct heteroepitaxy of PNAs on a flat substrate is constrained by the mismatch in crystalline symmetry and lattice parameters between the substrate and epitaxial nanowires. This study presents a novel approach termed "self-competitive growth" for heteroepitaxy of CsPbBr(3) PNAs on mica. The key to inducing the self-competitive growth of CsPbBr(3) PNAs on mica involves restricting the nucleation of CsPbBr(3) nanowires in a high-adsorption region, which is accomplished by overlaying graphite sheets on the mica surface. Theoretical calculations and experimental results demonstrate that CsPbBr(3) nanowires oriented perpendicular to the boundary of the high-adsorption area exhibit greater competitiveness in intercepting the growth of nanowires in the other two directions, resulting in PNAs with a consistent orientation. Moreover, these PNAs exhibit low-threshold and stable amplified spontaneous emission under one-, two-, and three-photon excitation, indicating their potential for an integrated laser array.

摘要：
Different from the conventional Zinc-Air batteries which only involves oxygen reduction and evolution (ORR/ OER) in the cathode, the cathode of rechargeable zinc-air/iodide hybrid batteries (ZAIHBs), with the addition of I- species, involves I- electrooxidation (IOR) during charging and oxygen/iodate reduction (ORR and IDR) during discharging. This work reports the synthesis of a hierarchically porous tungsten-based nitrogen-doped carbon framework (W/N/C) with abundant WNx active sites and numerous ultrafine WN nanoclusters and explores their application as a trifunctional IOR/ORR/IDR electrocatalyst for ZAIHBs. The formation mechanism of ZIF-8-derived W/N/C framework as well as its structural and compositional features were investigated. The catalyst demonstrates high trifunctional catalytic activity and robust durability towards IOR/ORR/IDR in alkaline condition, owing to the uniform copresence of the numerous sub-nanometer-sized WN nanoclusters and the abundant single atom WNx sites in the hierarchically structured carbon framework. When applied in homemade ZAIHBs, it revealed a high peak energy density (141.9 mW cm-2) and remarkable cycling stability (65 h), outperforming the commercial Pt/C catalysts. This work demonstrates the multi-functional electrocatalytic activity of tungsten-based non-noble metal electrocatalyst for high-performance ZAIHBs.

摘要：
In this paper, the evolution characteristics of periodic transmission of circularly symmetric multi-ring solitons in optical nonlocal materials based on nonlinear Schrödinger equation are investigated in detail. The transmission expression of circularly symmetric multi-ring solitons has been derived. It was found that the number and size of rings in these solitons can be controlled by initial parameters. The transmission of circularly symmetric multi-ring solitons is similar to that of high-order temporal solitons in nonlinear fibers, exhibiting periodic variations. When the input energy is a specific value, the statistical width of circularly symmetric multi-ring solitons remains constant during transmission, otherwise it exhibits periodic changes, which can be considered as generalized breathing solitons. The influence of various parameters on the transmission characteristics has been analyzed in detail, and some important transmission characteristics have been intuitively demonstrated through numerical simulation.
摘要：
Hair editing is challenging due to the complexity and variety of hair materials and shapes. Existing methods employ reference images or user-painted masks to edit hair and have achieved promising results. However, discrepancies in color and shape between the source and target hair can occasionally result in unrealistic results. Therefore, we propose a new hair editing method named HairManip, which decouples the hair information from the input source image into shape and color components. We then train hairstyle and hair color editing sub-networks to handle this complex information independently. To further enhance editing efficiency and accuracy, we introduce a latent code preprocessing module that effectively extracts meaningful features from hair regions, thereby improving the model’s editing capabilities. The experimental results demonstrate that our method achieves significant results in editing accuracy and authenticity, thanks to the carefully designed network structure and loss functions. Code can be found at https://github.com/Zlin0530/HairManip .

Talking face generation;Lip sync;Face motion;Virtual reality;Multimodality
摘要：
In this paper, we present TellMeTalk, an innovative approach for generating expressive talking face videos based on multimodal inputs. Our approach demonstrates robustness across various identities, languages, expressions, and head movements. It overcomes four key limitations of existing talking face video generation methods: (1) reliance on single -modal learning from audio or text, lacking the complementary nature of multimodal inputs; (2) deployment of traditional convolutional neural network generation, leading to restricted capture of spatial features; (3) the absence of natural head movements and expressions; and (4) limitations of artifacts, prominent boundaries caused by image overlapping, and unclear mouth regions. To address these challenges, we propose a face motion network to imbue character images with facial expressions and head movements. We also take text and reference audio as input to generate personalized audio. Furthermore, we introduce a generator equipped with a crossattention module and Fast Fourier Convolutional blocks to model spatial dependencies. Finally, a face restoration module is designed to reduce artifacts and prominent boundaries. Extensive experiments demonstrate our method produces high -quality expressive talking face videos. Compared to state-of-the-art approaches, our method exhibits superior performance in terms of video quality and precise synchronization of lip movements. The source code is available at https://github.com/lifemo/TellMeTalk.

color image encryption;hyperchaotic system;region of interest;security analysis
摘要：
The significance of safeguarding the security of image information has escalated significantly, owing to the exponential proliferation of digital images containing sensitive information being disseminated on the Internet. In this paper, we first propose a novel 4D hyperchaotic system and design a new image encryption algorithm in conjunction with the hyperchaotic system. The algorithm uses a split random swap permutation method to permute the image and combines the S-box to diffuse the image. To improve the diffusivity of this encryption algorithm, a cross-random diffusion method is designed to diffuse the image again. Then, we propose a region of interest (ROI) encryption scheme for images. This scheme can automatically identify irregular privacy targets in images and encrypt them. To ensure the security of the region of interest location information during transmission, the scheme compresses the location information of the privacy target using a run-length encoding technique and then embeds the compressed data into the ciphertext image using reversible steganography based on histogram shift. The experimental results and security analysis unequivocally demonstrate that the image encryption algorithm proposed in this paper exhibits robust resistance against a wide array of attacks, thereby ensuring a high level of security. Additionally, the devised image ROI encryption scheme effectively safeguards diverse privacy targets.
摘要：
Soil surface carbon dioxide (CO2) fluxes hold significant implications for comprehending carbon cycling, global climate change, and ecosystem functioning. Accurate understanding and quantification of this flux are crucial for assessing the carbon dynamics of ecosystems and predicting the impacts of climate change. In this study, we analyzed the variation pattern of CO2 concentration within the accumulated chamber from Fick's law, accounting for diffusion gradient effect and considering leakage effect. We developed a simple model to measure the soil surface CO2 flux, and used the model to calculate the values of CO2 fluxes on a specific soil surface. Comparing the fitting results of the proposed nonlinear model with traditional linear models for the measurement data, we found that the linear model underestimated by at least 18%, even up to 45%. Overall, our research indicates that the proposed model exhibits significant advancement and higher predictive reliability, successfully evaluating soil surface CO2 flux.

Abstract Understanding how resilient forests are to ecological engineering projects (EEPs) is essential to forest management and ecosystem health. Despite growing evidence that EEPs achieve increasing carbon stocks, whether such benefits can be sustainable and what are the consequences of EEPs on forest health remain unclear. This study aimed to investigate the long‐term effects of EEPs using forest resilience from aspects of resistance and recovery, by applying a change detection algorithm (breaks for additive seasonal and trend; BFAST) spatially on net ecosystem production (NEP) (proxy for carbon stocks) time series (1981–2019) in red soil hilly region (RSHR) of subtropical China. The spatial parameters (e.g., the number, magnitude, and time of changes) used to construct resilience metrics were generated based on BFAST‐derived breakpoints. These metrics were then utilized to analyze the dynamics of forest resilience in relation to EEPs factors in terms of plantation area, forest type, and stand age. Our results observed 92.77% of breakpoints in NEP after 2000, which corresponds well with the periods that multiple EEPs were conducted. NEP resilience showed great variability during 2001–2019, with a positive increasing trend in resistance (R2 = 0.72) and a continuous decline (R2 = 0.37) in recovery, indicating an unhealthy ecosystem in RSHR. Our findings revealed that forest resistance was strongly associated with plantation area (R = 0.71), and the presence of monoculture and young coniferous forest may be the potential factors for the decline in recovery. This suggested that forest resilience in RSHR is mainly modulated by large‐scale EEPs.

摘要：
This study aimed to explore the relationship between life events and non-suicidal self-injury (NSSI) in college students, as well as the mediating effect of sleep disturbances and psychotic-like experiences (PLEs). After excluding invalid questionnaires, 5,754 were retained, and the valid efficiency was 75.94%. The subjects were aged 16 to 29 years (M = 19.166; SD = 1.392), with 1,969 males (34.22%) and 3,785 females (65.78%). Life events, sleep disturbances, PLEs, and NSSI were assessed using standard scales. Data were analyzed by Pearson Correlation Analysis and bias-correction percentile Bootstrap method. The results show that (1) life events were significant positive predictors of NSSI, sleep disturbances, and PLEs; (2) sleep disturbances, PLEs, and the chain mediation between the two, were mediators between life events and NSSI. Life events are thus shown to be an important external factor influencing NSSI in university students, and this process is mediated through sleep disturbances, PLEs, and the chain between the two. Interventions for NSSI can therefore be made by improving college students’ sleep quality and reducing PLEs.
