| 1 | Reactive adsorption of thiophene on Ni/ZnO adsorbent:Effect of ZnO textural structure on the desulfurization activity显示文摘To better understand the nature of reactive adsorption of thiophene on Ni/ZnO adsorbent,the effect of ZnO textural structure on the desulfurization activity was investigated.ZnO materials were synthesized by low-temperature solid-state reaction and the corresponding Ni/ZnO adsorbents were prepared by incipient impregnation method.The analysis results showed that the crystalline sizes of ZnO as-synthesized as well as the BET surface areas varied obviously with the calcination temperature.The activity evaluations indicated that the Ni/ZnO adsorbents prepared with ZnO possessed a favorable textural structure as active component exhibited good activity of removing thiophene.The evolutions of the main crystalline phases of Ni/ZnO adsorbents before and after reaction confirmed that ZnO played a crucial role in taking up S element and converting it into ZnS in the reactive adsorption process.It was concluded that ZnO with larger surface area and smaller crystal particles resulted in better desulfurization activity,which may be the main reason for the different activities of the Ni/ZnO adsorbents prepared with ZnO calcined at different temperatures. | Jingcheng Zhang Yunqi Liu Shuang Tian Yongming Chai Chenguang Liu | 2010 | Journal of Natural Gas Chemistry2010，19，3： | 13 |
| 2 | Effect of shrub-grass vegetation coverage and slope gradient on runoff and sediment yield under simulated rainfall显示文摘Evaluating the benefits of sediment and runoff reduction in different vegetation types is essential for studying the mechanisms of soil and water conservation on the Loess Plateau.The experiment was conducted in shrub-grass plots with nine levels of mixed vegetation coverage from 0%to 70%,three slopes(10,15,and 20)and two rainfall intensities(1.0 and 2.5 mm/min).The results showed that the vegetation coverage and slope gradient significantly affect runoff and sediment yield.Shrub-grass vegetation coverage had a significant effect on the runoff start-time,runoff flow velocity,runoff rate,and soil erosion rate on hillslopes.Mixed vegetation coverage could effectively delay the runoff starttime and decrease the runoff flow velocity.However,the effects of the slope gradient on runoff and sediment yield are opposite to those of vegetation coverage.Shrub-grass vegetation coverage could effectively increase runoff and sediment yield reduction benefits,while their benefits were affected by the rainfall intensity.At the 1.0 mm/min rainfall intensity,the reduction in the sediment production rate was greater than that under the 2.5 mm/min intensity.However,when the shrub-grass vegetation coverage exceeded 42%,the runoff reduction benefit was more obvious at higher rainfall intensities.The cumulative sediment yield increased with increasing cumulative runoff,and the rate of increase in the cumulative runoff was greater than that of the cumulative sediment yield with increasing of shrub-grass vegetation coverage.Moreover,there was a power function relationship between cumulative sediment yield and cumulative runoff yield(P<0.05).Our paper is expected to provide a good reference on the ecological environment and vegetation construction on the Loess Plateau. | Dandan Han Jingcheng Deng Chaojun Gu Xingmin Mu Peng Gao Jianjian Gao | 2021 | International Journal of Sediment Research2021，36，1： | 8 |
| 3 | Arc corrosion behavior of Cu-Ti_3AlC_2 composites in air atmosphere显示文摘The arc corrosion evolution of Cu-20 vol.% Ti_3 AlC_2 cathodes is presented here. After eroded by 3, 4, 5, 6, 7, 8, 9, 10 kV DC voltage, respectively, the surface morphologies were characterized by field emission scanning electron microscope with craters and protrusions. Compared to small craters and dense protrusions of the morphology by high voltage, the eroded surface was covered with bigger craters and sparse protrusions at low voltage. No crack was discovered on the surface even at 10 kV. By means of energy dispersive spectroscopy and Raman spectroscopy, the decomposition of Cu-20 vol.% Ti_3 AlC_2 cathode to CuO,Al__2 O_3 and TiO_2 were proved. Meanwhile, W anode is oxidized to WO_2. The peak current increases with the increasing breakdown voltage, which is recorded by a digital memory oscilloscope. | HUANG XiaoChen FENG Yi QIAN Gang ZHAO Hao SONG ZhaoKun ZHANG JingCheng ZHANG XueBin | 2018 | Science China(Technological Sciences)2018，61，4： | 6 |
| 4 | Electronic-property dependent interactions between tetracycline and graphene nanomaterials in aqueous solution显示文摘Understanding the interactions between graphene nanomaterials(GNMs) and antibiotics in aqueous solution is critical to both the engineering applications of GNMs and the assessment of their potential impact on the fate and transport of antibiotics in the aquatic environment. In this study, adsorption of one common antibiotic, tetracycline, by graphene oxide(GO) and reduced graphene oxide(RGO) was examined with multi-walled carbon nanotubes(MWCNTs) and graphite as comparison. The results showed that the tetracycline adsorption capacity by the four selected carbonaceous materials on the unit mass basis followed an order of GO > RGO > MWCNTs > graphite. Upon normalization by surface area,graphite, RGO and MWCNTs had almost the same high tetracycline adsorption affinity while GO exhibited the lowest. We proposed π-electron-property dependent interaction mechanisms to explain the observed different adsorption behaviors. Density functional theory(DFT) calculations suggested that the oxygen-containing functional groups on GO surface reduced its π-electron-donating ability, and thus decreased the π-based interactions between tetracycline and GO surface. Comparison of adsorption efficiency at different p H indicated that electrostatic interaction also played an important role in tetracycline-GO interactions. Site energy analysis confirmed a highly heterogeneous distribution of the binding sites and strong tetracycline binding affinity of GO surface. | Lin He Fei-fei Liu Mengyao Zhao Zhen Qi Xuefei Sun Muhammad Zaheer Afzal Xiaomin Sun Yanhui Li Jingcheng Hao Shuguang Wang | 2018 | Journal of Environmental Sciences2018，30，4： | 4 |
| 5 | Accelerated solution of the transmission maintenance schedule problem:a Bayesian optimization approach显示文摘To maximize the maintenance willingness of the owner of transmission lines,this study presents a transmission maintenance scheduling model that considers the energy constraints of the power system and the security constraints of on-site maintenance operations.Considering the computational complexity of the mixed integer programming(MIP)problem,a machine learning(ML)approach is presented to solve the transmission maintenance scheduling model efficiently.The value of the branching score factor value is optimized by Bayesian optimization(BO)in the proposed algorithm,which plays an important role in the size of the branch-and-bound search tree in the solution process.The test case in a modified version of the IEEE 30-bus system shows that the proposed algorithm can not only reach the optimal solution but also improve the computational efficiency. | Jingcheng Mei Guojiang Zhang Donglian Qi Jianliang Zhang | 2021 | Global Energy Interconnection2021，4，5： | 3 |

| 10 | Identifying human body states by using a flexible integrated sensor显示文摘Flexible sensors are required to be lightweight,compatible with the skin,sufficiently sensitive,and easily integrated to extract various kinds of body vital signs during continuous healthcare monitoring in daily life.For this,a simple and low-cost flexible temperature and force sensor that uses only two carbon fiber beams as the sensing layer is reported in this work.This simple,flexible sensor can not only monitor skin temperature changes in real time but can also extract most pulse waves,including venous waves,from most parts of the human body.A pulse diagnostic glove containing three such flexible sensors was designed to simulate pulse diagnostic methods used in traditional Chinese medicine.Wearable equipment was also designed in which four flexible sensors were fixed onto different body parts(neck,chest,armpit,and fingertip)to simultaneously monitor body temperature,carotid pulse,fingertip artery pulse,and respiratory rate.Four important physiological indicators—body temperature(BT),blood pressure(BP),heart rate(HR),and respiratory rate(RR)—were extracted by the wearable equipment and analyzed to identify exercise,excited,tired,angry,and frightened body states. | Ying Jin Guoning Chen Kete Lao Songhui Li Yong Lu Yufeng Gan Zhundong Li Jiajia Hu Jingcheng Huang Jinxiu Wen Honggui Deng Min Yang Zhiming Chen Xiaoyan Hu Baowen Liang Jianyi Luo | 2020 | npj Flexible Electronics2020，4，1： | 2 |

| 12 | Tonifying kidney therapy for stable chronic obstructive pulmonary disease: a systematic review显示文摘OBJECTIVE: To evaluate the efficacy and safety of tonifying kidney therapy(Bushen, TK) for stable chronic obstructive pulmonary disease(COPD).METHODS: Randomized controlled trials(RCTs) of TK use for treatment of stable COPD were searched in four databases including Pub Med, the Cochrane Library, Chinese Biomedical Literature Database,and China National Knowledge Infrastructure Database from inception to December 2017. Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies. Rev Man 5.3 software was used for the Meta-analysis.RESULTS: Eight RCTs involving 809 patients with stable COPD were included. Compared with the conventional Western Medicine(CWM) group, the TK group(TK combined with CWM) showed significant improvements in the effectiveness rates(RR =1.37, 95% CI 1.22 to 1.53, P < 0.000 01) and 6-min walk distance in meters(MD 11.92, 95% CI 3.52 to20.32, P = 0.005), this study also showed that the TK group can decrease The Traditional Chinese Medicine Syndrome Score(MD-8.01, 95% CI-12.89 to-3.13, P = 0.001). The lung function [forced expiratory volume in one second%(FEV1%), FEV1/forced vital capacity] showed no difference between the TK and control groups.CONCLUSION: For patients with stable COPD, TK can improve the clinical effectiveness and exercise capacity but fail to improve the patient's symptoms. Because of the low methodological quality of the included trials, additional high-quality and large-scale RCTs are required. | Gao Zhen Liu Yingying Xu Yizhe Dong Jingcheng | 2020 | Journal of Traditional Chinese Medicine2020，40，2： | 2 |
| 13 | Real-time controller hardware-in-the-loop co-simulation testbed for cooperative control strategy for cyber-physical power system显示文摘Various distributed cooperative control schemes have been widely utilized for cyber-physical power system(CPPS),which only require local communications among geographic neighbors to fulfill certain goals.However,the process of evaluating the performance of an algorithm for a CPPS can be affected by the physical target characteristics and real communication conditions.To address this potential problem,a testbed with controller hardware-in-the-loop(CHIL)is proposed in this paper.On the basis of a power grid simulation conducted using the real-time simulator RT-LAB developed by the company OPAL-RT,along with a communication network simulation developed with OPNET,multiple distributed controllers were developed with hardware devices to directly collect the real-time operating data of the power system model in RT-LAB and provide local control.Furthermore,the communication between neighboring controllers was realized using the cyber system modelin OPNET with an Ethernet interface.The hardware controllers produced a real-world control behavior instead of a digital simulation,and precisely simulated the dynamic features of a CPPS with high speed.A classic cooperative control case for active power output was studied to explain the integrated simulation process and validate the effectiveness of the co-simulation testbed. | Zhenyu Wang Donglian Qi Jingcheng Mei Zhenming Li Keting Wan Jianliang Zhang | 2021 | Global Energy Interconnection2021，4，2： | 2 |
| 14 | Stable ZnO/ionic liquid hybrid materials: novel dual-responsive superhydrophobic layers to light and anions显示文摘Novel dual-responsive superhydrophobic hybrid materials,ZnO/SAMs(self-assembled monolayers)of ionic liquids(ILs)with different counter-anions(I-,BF4-,PF6-and Tf2N-),were synthesized and characterized.ZnO nanoparticles were first deposited on glass surfaces to produce roughness.Next,SAMs of fluorinated-alkyl-3-(3-triethoxysilylpropyl)-4,5-dihydro-imidazoliumiodide(abb.[C8Ftespim]I)were grafted onto these surfaces via-Si-O-covalent bonds using self-assembly technique.The Iion could be subsequently exchanged with BF4-,PF6-or Tf2N-through a simple aqueous anion-exchange reaction.The ZnO/ILs hybrid layers were characterized by atomic-force microscopy(AFM),scanning-electron microscopy(SEM)and X-ray photoelectron spectroscopy(XPS).Their wettability was estimated through the measurements of static and dynamic contact angles(CAs).Compared to corresponding films of ZnO/[C8Ftespim]I with CAs 140.7°±2.0°,films of ZnO/[C8Ftespim]PF6 and ZnO/[C8Ftespim]Tf2N showed CAs with 154.0°±2.0°and 152.0°±2.0°,respectively that remained for a long time.This result suggests that anion-exchange can afford superhydrophobic materials.In addition,the wettability of ZnO/[C8Ftespim]X hybrid layers can be reversibly switched by altering ultraviolet(UV)irradiation and dark storage,which shows a photo-induced reversible switch of wettability.The synergistic action of ZnO nanoparticles and SAMs of ILs produced light-anion dual-responsive superhydrophobic materials with ideal stability. | LI HongLiang XIN BingWei FENG Lei HAO JingCheng | 2014 | Science China Chemistry2014，57，7： | 2 |

| 16 | Reliability modeling of the bivariate deteriorating product with both monotonic and non-monotonic degradation paths显示文摘Fiber optical gyroscope(FOG)is a highly reliable navigation element,and the degradation trajectories of its two accuracy indexes are monotonic and non-monotonic respectively.In this paper,a flexible accelerated degradation testing(ADT)model is used for analyzing the bivariate dependent degradation process of FOG.The time-varying copulas are employed to consider the dynamic dependency structure between two marginal degradation processes as the Wiener process and the inverse Gaussian process.The statistical inference is implemented by utilizing an inference function for the margins(IFM)approach.It is demonstrated that the proposed method is powerful in modeling the joint distribution with various margins. | SUN Fuqiang GUO Hongxuan LIU Jingcheng | 2021 | Journal of Systems Engineering and Electronics2021，32，4： | 2 |
| 17 | Intraspecific Polymorphism of Rice Frog,Fejervarya multistriata(Anura: Ranidae),in Lingnan,Huangshan,China显示文摘Many anuran species exhibit striking color and/or pattern polymorphisms.We sampled 599 adult rice frogs,Fejervarya multistriata,from a rice paddy in the periphery of the Lingnan Nature Reserve(Huangshan,Anhui).We recognized ten morphs based on three relatively stable and distinct morphological characters: dorsal ground color(green or gray),middorsal stripe(absence,wide,or narrow),occipital rusty spot(absence or presence).The grey individuals are more common and larger than the green individuals(frequency 88.1 vs.11.9%,respectively) and(SVL 39.4–36.6 vs.35.7–34.6 mm,respectively).There is a higher proportion of individuals with a middorsal stripe(59.7%) while absence of the occipital rusty spot is more common in the population(82.3%).We expect additional studies in different habitat types would help build our understanding of the relationship between color polymorphism and habitat,geography,and climate. | Diancheng YANG Lifang PENG Jingcheng XU Song HUANG | 2017 | Asian Herpetological Research2017，18，1： | 2 |

| 19 | The Diversity of Soil Fauna Communities in the Karst Cave Wetland of Maolan Nature Reserve显示文摘From March 2014 to February 2015, the soil fauna community in the karst cave wetland of Maolan Nature Reserve was investigated. A total of 3,820 soil fauna was obtained, belonging to 31 orders, 11 classes, and 3 phyla. The dominant groups were Araneae, Coleoptera and Hymenoptera, accounting for 48.90% of the total catch. There were 18 common groups and 10 rare groups. The diversity analysis showed that the Banzhai karst cave wetland had the largest soil fauna community diversity index and evenness index and that the Dongsai karst cave wetland had the largest number of groups and individuals. The seasonal variation of the soil fauna in the karst cave wetlands was analyzed: the number of soil fauna individuals showed a downtrend in summer, autumn, spring and winter; there were the highest number of phytophagous soil fauna, followed by predatory soil fauna and saprophagous soil fauna. | LAN Hongbo RAN Jingcheng YAO Wuqing WANG Wanhai YAO Zhengming MENG Huili | 2018 | Journal of Landscape Research2018，10，6： | 2 |
| 20 | HSO_3-functionalized Br nsted acidic ionic liquids promote esterification of aromatic acid显示文摘Esterification of aromatic acid can be promoted via HSO3-functionalized Br nsted acidic ionic liquids (ILs). Under the optimum conditions, using 1-(3-sulfonic acid) propyl-3-methylimidazolium hydrogen sulfate ([MimC3SO3H][HSO4]) and 1-(4-sulfonic acid) butyl-3-methylimidazolium hydrogen sulfate ([MimC 4 SO 3 H][HSO4 ]) as dual solvent-catalysts, the conversion of esterification of aromatic acid was determined to be more than 90%, indicating that HSO3-functionalized ILs show much better catalytic ability than those of non-functionalized ionic liquids. The separation of desired product was easily performed by extraction with diethyl ether and these HSO3-functionalized ILs could be reused 7 times after vacuum drying. Our data represent an environmentally friendly method for the preparation of aromatic esters. | ZHOU FengYan XIN BingWei HAO JingCheng | 2013 | Chinese Science Bulletin2013，58，26： | 2 |
