| 2 | Abundant heterointerfaces in MOF-derived hollow CoS_(2)-MoS_(2) nanosheet array electrocatalysts for overall water splitting显示文摘Rational coupling of hydrogen evolution reaction(HER) and oxygen evolution reaction(OER) catalysts is extremely important for practical overall water splitting,but it is still challenging to construct such bifunctional heterostructures.Herein,we present a metal-organic framework(MOF)-etching strategy to design free-standing and hierarchical hollow CoS_(2)-MoS_(2) heteronanosheet arrays for both HER and OER.Resulting from the controllable etching of MOF by MoO_(4)^(2-) and in-situ sulfuration,the obtained CoS_(2)-MoS_(2) possesses abundant heterointerfaces with modulated local charge distribution,which promote water dissociation and rapid electrocatalytic kinetics.Moreover,the two-dimensional hollow array architecture can not only afford rich surface-active sites,but also facilitate the penetration of electrolytes and the release of evolved H_(2)/O_(2) bubbles.Consequently,the engineered CoS_(2)-MoS_(2) heterostructure exhibits small overpotentials of 82 mV for HER and 266 mV for OER at 10 mA cm^(-2).The corresponding alkaline electrolyzer affords a cell voltage of 1.56 V at 10 mA cm^(-2) to boost overall water splitting,along with robust durability over 24 h, even surpassing the benchmark electrode couple composed of IrO_(2) and Pt/C The present work may provide valuable insights for developing MOF-derived heterogeneous electrocatalysts with tailored interface/surface structure for widespread application in catalysis and other energyrelated areas. | Yuanjian Li Wenyu Wang Baojun Huang Zhifei Mao Rui Wang Beibei He Yansheng Gong Huanwen Wang | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |
| 3 | Environmental microcystin exposure triggers the poor prognosis of prostate cancer: Evidence from case-control, animal, and in vitro studies显示文摘Microcystin-leucine-arginine(MC-LR)is positively linked with multiple cancers in humans.However,the association between MC-LR and the risk and prognosis of prostate cancer has not been conducted in epidemiological studies.No reported studies have linked MC-LR exposure to the poor prognosis of prostate cancer by conducting experimental studies.The content of MC-LR was detected in most of the aquatic food in wet markets and supermarkets in Nanjing and posed a health risk for consumers.MC-LR levels in both prostate cancer tissues and serum were significantly higher than controls.The adjusted odds ratio(OR)for prostate cancer risk by serum MC-LR was 1.75(95%CI:1.21-2.52)in the whole subjects,and a positive correlation between MC-LR and advanced tumor stage was observed.Survival curve analysis indicated patients with higher MC-LR levels in tissues exhibited poorer overall survival.Human,animal,and cell studies confirmed that MC-LR exposure increases the expression of estrogen receptor-α(ERα)and promotes epithelial-mesenchymal transition(EMT)in prostate cancer.Moreover,MC-LR-induced decreased E-cadherin levels,increased vimentin levels,and increased migratory and invasive capacities of prostate cancer cells were markedly suppressed upon ERαknockdown.MC-LR-induced xenograft tumor growth and lungmetastasis in BALB/c nude mice can be effectively alleviated with ERαknockdown.Our data demonstrated that MC-LR upregulated vimentin and downregulated E-cadherin through activating ERα,promoting migration and invasion of prostate cancer cells.Our findings highlight the role of MC-LR in prostate cancer,providing new perspectives to understand MC-LR-induced prostatic toxicity. | Chun Pan Haixiang Qin Minghao Yan Xuefeng Qiu Wenyue Gong Wenxin Luo Hongqian Guo Xiaodong Han | 2023 | Journal of Environmental Sciences2023，，5： | 1 |

| 6 | Delay-CJ:A novel cryptojacking covert attack method based on delayed strategy and its detection显示文摘Cryptojacking is a type of resource embezzlement attack,wherein an attacker secretly executes the cryptocurrency mining program in the target host to gain profits.It has been common since 2017,and in fact,it once became the greatest threat to network security.To better prove the attack ability the harm caused by cryptojacking,this paper proposes a new covert browser-based mining attack model named Delay-CJ,this model was deployed in a simulation environment for evaluation.Based on the general framework of cryptojacking,Delay-CJ adds hybrid evasion detection techniques and applies the delayed execution strategy specifically for video websites in the prototype implementation.The results show that the existing detection methods used for testing may become invalid as result of this model.In view of this situation,to achieve a more general and robust detection scheme,we built a cryptojacking detection system named CJDetector,which is based on cryptojacking process features.Specifically,it identifies malicious mining by monitoring CPU usage and analyzing the function call information.This system not only effectively detects the attack in our example but also has universal applicability.The recognition accuracy of CJDetector reaches 99.33%.Finally,we tested the web pages in Alexa 50K websites to investigate cryptojacking activity in the real network.We found that although cryptojacking is indeed on the decline,it remains a part of network security threats that cannot be ignored. | Guangquan Xu Wenyu Dong Jun Xing Wenqing Lei Jian Liu Lixiao Gong Meiqi Feng Xi Zheng Shaoying Liu | 2023 | Digital Communications and Networks2023，9，5： | 0 |
| 7 | Application of High-Resolution Remote Sensing Technology in Quantitative Study on Coseismic Surface Rupture Zones: An Example of the 2008 M_w7.2 Yutian Earthquake显示文摘Objective Nowadays,high-resolution remote sensing technology has brought new changes to surveys of earthquakes,and the quantitative study of seismic faults based on this technology has become a trend in the world (Barzegari et al.,2017).An Mw 7.2 earthquake occurred in Yutian of Xinjiang on the western end of the Altyn Tagh fault on March 21 st,2008.It is difficult to access this depopulated zone because of the high altitude and only 1-2 months of snowmelt.This study utilized high-resolution remote sensing to examine the geometric and kinematic characteristics of the surface rupture zone produced by this event.It will cast new light on the application of high-resolution remote sensing to the quantitative research of earthquakes. | SHAN Xinjian HAN Nana SONG Xiaogang GONG Wenyu QU Chunyan ZHANG Yingfeng | 2018 | Acta Geologica Sinica(English Edition)2018，92，6： | 0 |
| 8 | Tunnelling of electrons via the neighboring atom显示文摘As compared to the intuitive process that the electron emits straight to the continuum from its parent ion,there is an alternative route that the electron may transfer to and be trapped by a neighboring ionic core before the eventual release.Here,we demonstrate that electron tunnelling via the neighboring atomic core is a pronounced process in light-induced tunnelling ionization of molecules by absorbing multiple near-infrared photons.We devised a siteresolved tunnelling experiment using an Ar-Kr+ion as a prototype system to track the electron tunnelling dynamics from the Ar atom towards the neighboring Kr+by monitoring its transverse momentum distribution,which is temporally captured into the resonant excited states of the Ar-Kr+before its eventual releasing.The influence of the Coulomb potential of neighboring ionic cores promises new insights into the understanding and controlling of tunnelling dynamics in complex molecules or environment. | Ming Zhu Jihong Tong Xiwang Liu Weifeng Yang Xiaochun Gong Wenyu Jiang Peifen Lu Hui Li Xiaohong Song Jian Wu | 2024 | Light(Science & Applications)2024，13，1： | 0 |
| 9 | A paternal protein facilitates sperm RNA delivery to regulate zygotic development显示文摘Sperm contributes essential paternal factors,including the paternal genome,centrosome,and oocyte-activation signals,to sexual reproduction.However,it remains unresolved how sperm contributes its RNA molecules to regulate early embryonic development.Here,we show that the Caenorhabditis elegans paternal protein SPE-11 assembles into granules during meiotic divisions of spermatogenesis and later matures into a perinuclear structure where sperm RNAs localize.We reconstitute an SPE-11 liquid-phase scaffold in vitro and find that SPE-11 condensates incorporate the nematode RNA,which,in turn,promotes SPE-11 phase separation.Loss of SPE-11 does not affect sperm motility or fertilization but causes pleiotropic development defects in early embryos,and spe-11 mutant males reduce m RNA levels of genes crucial for an oocyte-to-embryo transition or embryonic development.These results reveal that SPE-11 undergoes phase separation and associates with sperm RNAs that are delivered to oocytes during fertilization,providing insights into how a paternal protein regulates early embryonic development. | Dongdong Li Shijing Huang Yongping Chai Ruiqian Zhao Jing Gong Qiangfeng Cliff Zhang Guangshuo Ou Wenyu Wen | 2023 | Science China(Life Sciences)2023，66，10： | 0 |
| 10 | A hybrid optimization approach for the heterogeneous vehicle routing problem with multiple depots cooperative operation显示文摘With the challenge of great growing of transport diversity for the automobile enterprises, the heterogeneous vehicle routing problem with multiple depots, multiple types of finished vehicles and multiple types of transport vehicles in finished vehicle logistics(HVRPMD) is modelled and solved. A multi-objective optimization model for HVRPMD is presented considering loading constraints to minimize the total cost and minimize the number of transport vehicles. Then a hybrid heuristic algorithm based on genetic algorithm and particle swarm optimization(GA-PSO) is developed. Moreover, a case study is used to evaluate the effectiveness of this algorithm. By comparing the GA-PSO algorithm with the traditional GA algorithm, the simulation results demonstrate the proposed GA-PSO algorithm is able to better support the HVRPMD problem in practice. Contributions of the paper are the modelling and solving of a complex HVRPMD in logistics industry. | 刘建胜 Tan Wenyue Jiang Hai Yu Gong | 2020 | High Technology Letters2020，26，1： | 0 |
| 11 | Optical,Radiative and Chemical Characteristics of Aerosol in Changsha City,Central China显示文摘Industrial pollution has a significant effect on aerosol properties in Changsha City,a typical city of central China.Therefore,year-round measurements of aerosol optical,radiative and chemical properties from 2012 to 2014 at an urban site in Changsha were analyzed.During the observation period,the energy structure was continuously optimized,which was characterized by the reduction of coal combustion.The aerosol properties have obvious seasonal variations.The seasonal average aerosol optical depth(AOD)at 500 nm ranged from 0.49 to 1.00,single scattering albedo(SSA)ranged from 0.93 to 0.97,and aerosol radiative forcing at the top of the atmosphere(TOA)ranged from−24.0 to 3.8 W m^−2.The chemical components also showed seasonal variations.Meanwhile,the scattering aerosol,such as organic carbon,SO42−,NO3−,and NH4+showed a decrease,and elemental carbon increased.Compared with observation in winter 2012,AOD and TOA decreased by 0.14 and−1.49 W m^−2 in winter 2014.The scattering components,SO42−,NO3−and NH4+,decreased by 12.8μg m^−3(56.8%),9.2μg m^−3(48.8%)and 6.4μg m^−3(45.2%),respectively.The atmospheric visibility and pollution diffusion conditions improved.The extinction and radiative forcing of aerosol were significantly controlled by the scattering aerosol.The results indicate that Changsha is an industrial city with strong scattering aerosol.The energy structure optimization had a marked effect on controlling pollution,especially in winter(strong scattering aerosol). | Xiaoyan WU Jinyuan XIN Wenyu ZHANG Chongshui GONG Yining MA Yongjing MA Tianxue WEN Zirui LIU Shili TIAN Yuesi WANG Fangkun WU | 2020 | Advances in Atmospheric Sciences2020，37，12： | 0 |
