| 1 | Amorphous TiO_2-supported Keggin-type ionic liquid catalyst catalytic oxidation of dibenzothiophene in diesel显示文摘Supported ionic liquid(IL) catalysts [C_nmim]_3PMo_(12)O_(40)/Am TiO_2(amorphous TiO_2) were synthesized through a one-step method for extraction coupled catalytic oxidative desulfurization(ECODS) system. Characterizations such as FTIR, DRS,wide-angle XRD, N_2 adsorption–desorption and XPS were applied to analyze the morphology and Keggin structure of the catalysts. In ECODS with hydrogen peroxide as the oxidant, it was found that ILs with longer alkyl chains in the cationic moiety had a better effect on the removal of dibenzothiophene. The desulfurization could reach 100% under optimal conditions, and GC–MS analysis was employed to detect the oxidized product after the reaction. Factors affecting the desulfurization efficiencies were discussed, and a possible mechanism was proposed. In addition, cyclic experiments were also conducted to investigate the recyclability of the supported catalyst. The catalytic activity of [C_(16)mim]_3 PMo_(12)O_(40)/Am TiO_2 only dropped from 100% to 92.9% after ten cycles, demonstrating the good recycling performance of the catalyst and its potential industrial application. | Zhendong Yu Donghui Wang Suhang Xun Minqiang He Ruliang Ma Wei Jiang Hongping Li Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 3 |
| 2 | A heterogeneous double chamber electro-Fenton with high production of H_(2)O_(2) using La–CeO_(2) modified graphite felt as cathode显示文摘Hydrogen peroxide synthesis by electro-reduction of O_(2) to substitute the current anthraquinone process has attracted a great deal of attention. Low oxygen utilization rate and low hydrogen peroxide production remain obstacles to electro-Fenton application. In situ H_(2)O_(2) generated by electrochemical reaction depends on the electrochemical performance of the cathode and the structure of the reactor. Here, novel graphite felt(GF) modified by La-doped CeO_(2)(La-CeO_(2)) was developed as a cathode. A new double chamber electro-Fenton reactor was proposed, where an organic ultrafiltration membrane was used to prevent H_(2)O_(2) from spreading to the anode. The effects of hydrothermal temperature, time and urea concentration on the electrochemical properties of graphite felt were investigated. The accumulated concentration of H_(2)O_(2) on the modified cathode reached 218.4 mg·L^(-1)in 1 h when the optimal conditions of hydrothermal temperature 120 ℃ and urea concentration 0.55%(mass) in 24 h. The degradation rate of methyl orange reached 98.29%. The new electro-Fenton reactor can efficiently produce hydrogen peroxide to degrade various organic substances and has a high potential for treating wastewater in the chemical industry. | Suhang Jiang Lijuan Tan Yujia Tong Lijian Shi Weixing Li | 2023 | Chinese Journal of Chemical Engineering2023，54，2： | 1 |

| 6 | Interspecific competition predicts the potential impact of little fire ant Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae) invasion on resident ants in southern China显示文摘The little fire ant Wasmannia auropunctata(Roger)is a major invasive species that seriously threatens the biodiversity of invaded areas.W.auropunctata was first reported in Chinese mainland in 2022 and its impact on native species is still unknown.To evaluate the impact of W.auropunctata invasion on the ant communities in southern China,a series of interspecific competition experiments were conducted in this study.The individual aggression index and group aggression experiments showed the advantage of W.auropunctata in competition with 5 resident ants under equal worker numbers.When encountering Anoplolepis gracilipes,Camponotus nicobarensis,Tetramorium bicarinatum,Polyrhachis dives,and Solenopsis invicta,W.auropunctata gradually gained a competitive advantage with an increase in its number of workers.In the group aggression experiments with equal worker numbers,there was a negative correlation between the body length and mortality rate of resident ants.The results of the foraging behavior experiments showed that W.auropunctata was able to dominate food resources under competition with Carebara diversa,which also displayed weak competition in the group aggression bioassay.In addition,the abilities to recruit workers and retrieve food were inhibited under competition with S.invicta and T.bicarinatum.The results of the nesting behavior experiments showed that in the 24-h bout of space resource competition,W.auropunctata was dominant over C.diversa,S.invicta,and T.bicarinatum.The results of this study show that W.auropunctata has certain advantages in competition for food and space resources over resident ants in southern China,and some resident ant species may be replaced in the future. | Lei Nie Bamisope Steve Bamisile Yuling Li Hao Ran Suhang Wang Lei Wang Yijuan Xu | 2023 | Insect Science2023，30，5： | 0 |
| 7 | Exploring the association of paid sick leave with healthcare utilization and health outcomes in the United States:a rapid evidence review显示文摘Objective:Paid sick leave(PSL)laws mandate employers give workers paid time off when they are sick or injured.This current study aims to examine whether access to PSL is associated with healthcare utilization and health outcomes and to summarize the types of utilization and outcomes which have been reported to be associated with PSL.Methods:We conducted a rapid evidence review.Our search of seven databases,including Medline,Embase,PsycINFO,Cochrane Library,CINAHL,Scopus,and JSTOR,on September 21,2020,identified 757 studies,30 of which were retained.Results:Previous evidence is mostly provided by cross-sectional studies with survey data.In this study,evidence suggests that PSL is significantly associated with some types of healthcare utilization and health outcomes.In terms of healthcare utilization,findings indicate PSL is associated with an increase in the use of some preventive sendees and a decrease in the use of emergency care;while findings are mixed regarding associations of PSL with health provider visits and the use of mammograms and pap smears.As for health outcomes,findings suggest PSL is associated with improved mental and self-rated health,decreased incidence of influenza-like illness,and lower occupational injuries and mortality rates.Conclusion:PSL may be an effective tool in improving some healthcare utilization and health outcomes.Future research could help identify mechanisms through which PSL access works and identify what policy components lead to better outcomes. | Suhang Song Brian H.Calhoun James E.Kucik Kristin J.Konnyu Renata Hilson | 2023 | Global Health Journal2023，7，1： | 0 |

| 10 | Photocatalytic oxidative of Keggin-type polyoxometalate ionic liquid for enhanced extractive desulfurization in binary deep eutectic solvents显示文摘A series of novel binary deep eutectic solvents(DESs)composed of choline chloride(ChCl)and formic acid(HCOOH)with different molar ratios have been successfully synthesized and applied in extractive desulfurization(EDS).Keggin-type polyoxometallate ionic liquid[TTPh]_(3)PW_(12)O_(40) was prepared and used as catalyst to enhance the EDS capacity by means of photocatalytic oxidative process.Both of the DESs and[TTPh]_(3)PW_(12)O_(40) ionic liquid catalyst were characterized in detail by Fourier transform infrared spectroscopy spectra(FT-IR),elemental analysis,and X-ray photoelectron spectroscopy(XPS).It was found that the molar ratios of Ch Cl:HCOOH had a major impact on desulfurization performance,and the optimal desulfurization capacity 96.5%was obtained by ChCl/5 HCOOH.Besides dibenzothiophene(DBT),the desulfurization efficiencies of 4-methylbenzothiophene(4-MDBT)and 4,6-dimethyldibenzothiophene(4,6-DMDBT),two kinds of DBT derivatives,were also investigated under the same experimental conditions.Moreover,the free radical scavenging experiments manifested that superoxide radical(·O_(2)^(-)) and hole(h^(+)) played important roles in the desulfurization system.After further analysis of the oxidation products by gas chromatography-mass spectrometry(GC–MS),the possible reaction mechanism was proposed.Thus,photocatalytic oxidative has been proved to be one of the efficient approaches for enhancing the extractive desulfurization performance in DES. | Linlan Wu Zhengxin Jiao Suhang Xun Minqiang He Lei Fan Chao Wang Wenshu Yang Wenshuai Zhu Huaming Li | 2022 | Chinese Journal of Chemical Engineering2022，35，4： | 0 |

| 12 | Monitoring Molecular Dynamics with Single-Molecule Electronic Devices and Fluorescence Techniques显示文摘Monitoring the dynamics of a single molecule provides unique insights into the fundamental physical and chemical properties of individual molecules.Over the past few decades,various approaches have been developed to enable the real-time and high-resolution detection at the single-molecule level.Among them,electrical and optical methods are the most promising tools,for the reason that electrical detection offers high resolution while optical technology provides non-invasive,targeted measurement with the added benefit of visualization.In this review,we summarized the current state-of-the-art electrical and optical techniques for single-molecule measurement and discussed their applications in detecting dynamic events such as conformational isomerizations,intermolecular interactions,chemical reactions,and biomolecular activities.In addition,we discussed the challenges and opportunities in this area and proposed possible directions for future development. | Lan Yang Zhizhuo Zhang Cong Zhao Yani Huo Enyu Zhang Suhang He Chuancheng Jia Xuefeng Guo | 2023 | Chinese Journal of Chemistry2023，41，21： | 0 |

| 14 | Leaky Cable Fixture Detection in Railway Tunnel Based on RW DCGAN and Compressed GS-YOLOv5显示文摘The communication system of high-speed trains in railway tunnels needs to be built with leaky cables fixed on the tunnel wall with special fixtures.To ensure safety,checking the regular leaky cable fixture is necessary to elimi-nate the potential danger.At present,the existing fixture detection algorithms are difficult to take into account detection accuracy and speed at the same time.The faulty fixture is also insufficient and difficult to obtain,seriously affecting the model detection effect.To solve these problems,an innovative detection method is proposed in this paper.Firstly,we presented the Res-Net and Wasserstein-Deep Convolution GAN(RW-DCGAN)to implement data augmentation,which can enable the faulty fixture to export more high-quality and irregular images.Secondly,we proposed the Ghost SENet-YOLOv5(GS-YOLOv5)to enhance the expression of fixture feature,and further improve the detection accuracy and speed.Finally,we adopted the model compression strategy to prune redundant channels,and visualized training details with Grad-CAM to verify the reliability of our model.Experimental results show that the algorithm model is 69.06%smaller than the original YOLOv5 model,with 70.07%fewer parameters,2.1%higher accuracy and 14.82 fps faster speed,meeting the needs of tunnel fixture detection. | Suhang Li Yunzuo Zhang Ruixue Liu Jiayu Zhang Zhouchen Song Yutai Wang | 2023 | Intelligent Automation & Soft Computing2023，，7： | 0 |
| 15 | Fracture toughness and destructive mechanism of ductile nanoporous metallic glass and its crystal-impregnated nanocomposite显示文摘Nanoporous metallic glasses(NPMGs)and crystalline/amorphous nanocomposites exhibit superior ductility over bulk macroscopic metallic glasses(MGs).Their fracture behaviors remain a mystery due to experimental technical limitations.In this work,the fracture behaviors of pre-cracked NPMGs and crystal-impregnated nanoporous metallic glasses(CINPMGs)are investigated through large-scale molecular dynamics simulations,and the MG and crystal phases are amorphous Cu_(50)Zr_(50)and crystalline B2CuZr,respectively.Fracture toughness is determined by simultaneously considering the surface energy and plastic dissipated energy.Our results confirm the excellent plasticity of both the pre-cracked NPMGs and CINPMGs.The progressive necking and ductile rupture of ligaments are responsible for generating NPMGs with prominent ductility and fracture toughness.Meanwhile,secondary cracking is also triggered,which can consume energy without extending the major crack,thus further improving fracture resistance.It is also found that the fracture toughness of NPMGs can be improved by increasing the solid fraction of MG,and linear relation between fracture toughness and solid fraction can be expected.Crystal impregnation effectively inhibits global failure as the crystal phase shields the individual amorphous ligaments.Homogeneous plastic flow characterized by shear bands is observed in CINPMGs,and this homogeneous global deformation is facilitated by the crystalline/amorphous interface.Besides,the fracture toughness of CINPMGs is higher than that of the constituent single phases,regardless of the volume fraction of each phase.Ashby material charts manifest that these two types of materials demonstrate promising potential in the material selection library for advanced structural design. | ZHANG YuHang XU JianFei HU YiQun SU Lei DING SuHang WU WenWang XIA Re | 2023 | Science China(Technological Sciences)2023，66，11： | 0 |
