Localized CdS homojunctions with optimal ratio of high and low index facets are constructed to dy-namically boost H_(2)O splitting into H_(2)energy by hydrothermal method in combination with calcination.By density functional theory,hall effect,and in situ diffuse reflectance infrared Fourier transform spec-troscopy,it is revealed that photo-irradiated e^(−)and h^(+)can be spatially separated and directionally trans-ferred to the reductive high-index facet{002}and oxidative low-index facet{110}of localized CdS homo-junction induced by Fermi level difference of both high and low index facets to dehydrogenate ^(∗)-OH and coupled ^(∗)-O intermediates for H_(2)and O_(2)yield,respectively,along with a solar conversion into hydrogen of 1.93%by AM 1.5 G irradiation at 65℃.The study work suggests a scientific perspective on the optimal ratio of high and low index facets to understand photo-generated charge carrier transfer dynamically and their photocatalytic principle for H_(2)O splitting reaction in kinetics.

自工业革命以来,二氧化碳(CO_(2))排放量迅速增加.将二氧化碳通过催化反应转化为高附加值产物,被认为是重要的减污降碳策略.然而,由于CO_(2)还原反应产物的多样性以及催化剂制备过程中可能残留的有机物质,导致难以准确评估催化剂的真实活性.尽管13CO_(2)同位素溯源技术已被广泛用于确定还原产物的碳源,但其严谨性不足可能导致溯源结果失真,影响了CO_(2)还原领域的发展.为了解决CO_(2)还原反应中催化剂活性评估的难题,汪圣尧等深入研究了同位素示踪原理,提出标准化同位素追溯新方法(Nat.Commun.,2023,14,2534).尽管气-质谱联用技术被视为普适方法,但现有方法难以充分分离复杂混合气体样品,因此需要谨慎对待溯源结果.13C-NMR光谱法常用于液体产物示踪,但由于自然界中存在13C同位素,这在一定程度上影响了同位素示踪技术的精确性.而1H-NMR因能识别与13C同位素相关的氢原子的特征分裂模式,而成为一种可行的替代方案.研究指出,同位素追踪在CO_(2)减排中的应用复杂,需要选择合适的气相色谱条件实现产物的有效分离,以确保溯源结果的可靠性.该研究还建立了同位素溯源检测的标准方法,并提供了同位素标记物的质谱指纹图谱.对于理解同位素溯源过程和推动CO_(2)还原研究具有重要意义.综上,对于CO_(2)还原反应潜在产物的溯源研究已成为衡量催化剂真实性能的关键指标之一.文章提出的标准化同位素溯源方法可作为该领域研究的可靠标准,并为实现真实可靠的CO_(2)还原反应提供有力保障.

As a new-style stochastic algorithm, the electromagnetism-like mechanism（EM） method gains more and more attention from many researchers in recent years. A novel model based on EM（NMEM） for multiobjective optimization problems is proposed, which regards the charge of all particles as the constraints in the current population and the measure of the uniformity of non-dominated solutions as the objective function. The charge of the particle is evaluated based on the dominated concept, and its magnitude determines the direction of a force between two particles. Numerical studies are carried out on six complex test functions and the experimental results demonstrate that the proposed NMEM algorithm is a very robust method for solving the multiobjective optimization problems.

The aim of testing based fault localization(TBFL) involves improving the efficiency of program debugging by providing developers with a guide of ranked list of suspicious statements. However, collection of testing information of the whole original test-suite is excessively expensive or even infeasible for developers to conduct TBFL. Traditional test-suite reduction(TSR) techniques are utilized to reduce the size of testsuite. However, they entail a time-consuming process of whole testing information collection. In this study, the distance based test-suite reduction(DTSR) technique is proposed. As opposed to the whole testing information,the distances among the test cases are used to guide the process of test-suite reduction in DTSR. Hence, it is only necessary to collect the testing information for a portion of the test cases for TSR and TBFL. The investigation on the Siemens and SIR benchmarks reveals that DTSR can effectively reduce the size of the given test-suite as well as the time cost of TBFL. Additionally, the fault locating effectiveness of DTSR results is close to that when the whole test-suite is used.

光催化水解离制氢过程中,光生载流子由生成位点向氧化还原位点艰难的动力学迁移及随后与中间产物反应大的过电位问题还没有被解决,严重阻碍了太阳光子转化为氢能的效率(STH).本文基于配体效应协同调控材料d带中心构建了CeO_(2)纳米线负载Ni_(2)P异质结光催化剂,继而解决上述动力学瓶颈.原位漫反射傅里叶变换红外光谱、霍尔效应等表征揭示光生电子和空穴在自发局域电场推动下,分别迁移至Ni_(2)P还原位点和CeO_(2)氧化位点,接着促使吸附在此的活性中间产物发生脱氢和氧耦合反应.性能测试显示,在AM 1.5G模拟太阳光辐照下,室温下的STH值达到了1.13%.本研究为通过协同调节d带中心提高异质结光催化剂的STH提供了独特的策略.

Viruses commonly create favorable cellular conditions for their survival through multiple mechanisms. Micro RNAs(mi RNAs), which function as post-transcriptional regulators, are utilized by human cytomegalovirus(HCMV) in its infection and pathogenesis. In the present study, the DNA replication inhibitor Geminin(GMNN) was identified to be a direct target of hcmv-mi R-US5-1. Overexpression of hcmv-mi R-US5-1 could block the accumulation of GMNN during HCMV infection, and the decrease of GMNN expression caused by hcmv-mi R-US5-1 or GMNN specific si RNA reduced HCMV DNA copies in U373 cells. Meanwhile, ectopic expression of hcmv-mi R-US5-1 and consequent lower expression of GMNN influenced host cell cycle and proliferation. These results imply that hcmv-mi R-US5-1 may affect viral replication and host cellular environment by regulating expression kinetics of GMNN during HCMV infection.

Objective The aim of the study was to study the clinical efficacy and prognosis of endoscopicallycutting the nasobiliary duct and leaving its residual segment as a biliary stent in the treatment of hilarcholangiocarcinoma (HC).Methods The clinical data of 55 patients with HC treated by endoscopic biliary drainage at theGastrointestinal Endoscopy Center of our hospital (Renmin Hospital of Wuhan University, China) fromAugust 2017 to August 2019 were retrospectively analyzed. According to different drainage schemes,patients were divided into the endoscopic nasobiliary cutting group (n = 26) and the endoscopic retrogradebiliary drainage (ERBD) group (n = 29). The postoperative liver function indexes, incidence of postoperativecomplications, median patency period of stents, and median survival time of patients were comparedbetween the two groups.Results Liver function indexes (total bilirubin, direct bilirubin, alanine aminotransferase, aspartateaminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase) were significantly decreased in55 patients a week postoperaticely (P 0.05).Conclusion The nasobiliary duct was cut

Exploring the vibrational properties of experimental or theoretical finding of new phase twodimensional(2D)materials is one key to expand their promising application.The GaGeTe monolayer with high carrier mobility,tunable band structure,and low cleavage energy attracts rapidly growing interests in electronics.However,their vibrational modes and phonon properties are not explored.Based on first-principles calculations within the framework of density functional perturbation theory,we systematically study the lattice vibrational modes as well as phonon thermal conductivity of single-layer GaGeTe,which could be exfoliated from the experimentally synthesized GaGeTe crystal.We find that the frequencies and intensities of A1g and Eg Raman modes,contributing to the main peaks in Raman spectra of monolayer GaGeTe,show distinct responses to different external strains.The calculated lattice thermal conductivity of GaGeTe is about 58 Wm-1 K1,which is comparable to that of MoS2(around 52 Wm1K1)and two orders of magnitude lower than that of graphene(2000 Wm1K1)at room temperature.This is mainly due to the partial couple for acoustic branches and low frequency optic phonon branches,moderate group velocity,strong anharmonic ZA phonon branch.Moreover,atom substitution at tellurium could be as an effective strategy to further decrease lattice thermal conductivity.Our findings fill in the gap about the thermal transport properties of GaGeTe monolayer and trigger for further experimental verification of the predicted properties.
