| 1 | Effects of surface chemical properties of activated coke on selective catalytic reduction of NO with NH_3 over commercial coal-based activated coke显示文摘Surface chemical properties of typical commercial coal-based activated cokes were characterized by Xray photoelectron spectroscopy(XPS) and acid-base titration, and then the influence of surface chemical properties on catalytic performance of activated cokes of NO reduction with NH3 was investigated in a fixed-bed quartz micro reactor at 150 ℃. The results indicate that the selective catalytic reduction(SCR) activity of activated cokes with the increase of its surface acidic sites and oxygen content,obviously, a correlation between catalytic activity and surface acidic sites content by titration has higher linearity than catalytic activity and surface oxygen content by XPS. While basic sites content by acid-base titration have not correlation with SCR activity. It has been proposed that surface basic sites content measured by titration may not be on adjacent of acidic surface oxides and then cannot form of NO2-like species, thus the reaction of reduction of NO with NH3 have been retarded. | Xie Wei Sun Zhongchao Xiong Yinwu Li Lanting Wu Tao Liang Daming | 2014 | International Journal of Mining Science and Technology2014，24，4： | 12 |
| 2 | Surface chemical properties and pore structure of the activated coke and their effects on the denitrification activity of selective catalytic reduction显示文摘In order to study the mechanism of selective catalytic reduction of activated coke to remove NO in low-temperature flue gas and provide some theoretical basis for the development of related technologies.The pore sizedistribution and BET specific surface area of AC were obtain by data analyzing of N2 adsorption/desorption isotherm at -196 ℃ and carbon matrix and surface chemistry of virgin activated coke samples were characterized by acid-base titration and XPS.The process of selective catalytic reduction of activated coke (AC) samples with NH3 as reducing agent was studied in a fixed bed reactor at 150 ℃.The result shows that pore size distribution or BET specific surface of activated cokes have not correlation with denitrification activity for SCR.The NO reduction activities of the activated cokes are apparent to increase with their surface oxygen element content and total amount of acidic sites.Obviously there is good linear relationship between the NH3 adsorption capacity and activity for SCR with linear correlation coefficient 0.943.It has been presented that adsorption of NH3 on acidic functional groups in the edge of large polycyclic aromatic ring of activated coke is key rate controlling step in the SCR heterogeneous catalytic reaction. | Wei Xie Daming Liang Lanting Li Sijian Qu Wu Tao | 2019 | International Journal of Coal Science & Technology2019，6，4： | 8 |
| 3 | Validation of dynamic cavitation model for unsteady cavitating flow on NACA66显示文摘Unsteady cavitating flow is extremely complicated and brings more serious damages and unignorable problems compared with steady cavitating flow.CFD has become a practical way to model cavitation;however,the popularly used full cavitation model cannot reflect the pressure-change that the bubble experiences during its life path in the highly unsteady flow like cloud cavitating.Thus a dynamic cavitation model(DCM)is proposed and it has been considered to have not only the first-order pressure effects but also zero-order effect and can provide greater insight into the physical process of bubble producing,developing and collapsing compared to the traditional cavitation model.DCM has already been validated for steady cavitating flow,and the results were reported.Furthermore,DCM is designed and supposed to be more accurate and efficient in modeling unsteady cavitating flow,which is also the purpose of this paper.The basic characteristic of the unsteady cavitating flow,such as the vapor volume fraction distribution and the evolution of pressure amplitude and frequency at different locations of the hydrofoil,are carefully studied to validate DCM.It is found that not only these characteristics mentioned above accord well with the experimental results,but also some detailed transient flow information is depicted,including the re-entrant jet flow that caused the shedding of the cavity,and the phenomenon of two-peak pressure fluctuation in the vicinity of the cavity closure in a cycle.The numerical results validate the capability of DCM for the application of modeling the complicated unsteady cavitating flow. | ZHANG XiaoBin ZHANG Wei CHEN JianYe QIU LiMin SUN DaMing | 2014 | Science China(Technological Sciences)2014，57，4： | 8 |
| 4 | Bismuth-Based Free-Standing Electrodes for Ambient-Condition Ammonia Production in Neutral Media显示文摘Electrocatalytic nitrogen reduction reaction is a carbon-free and energy-saving strategy for efficient synthesis of ammonia under ambient conditions.Here,we report the synthesis of nanosized Bi2O3 particles grown on functionalized exfoliated graphene(Bi2O3/FEG)via a facile electrochemical deposition method.The obtained free-standing Bi2O3/FEG achieves a high Faradaic efficiency of 11.2%and a large NH3 yield of 4.21±0.14μgNH3 h^-1 cm^-2 at-0.5 V versus reversible hydrogen electrode in 0.1 M Na2SO4,better than that in the strong acidic and basic media.Benefiting from its strong interaction of Bi 6p band with the N2p orbitals,binder-free characteristic,and facile electron transfer,Bi2O3/FEG achieves superior catalytic performance and excellent long-term stability as compared with most of the previous reported catalysts.This study is significant to design low-cost,high-efficient Bi-based electrocatalysts for electrochemical ammonia synthesis. | Ying Sun Zizhao Deng Xi‑Ming Song Hui Li Zihang Huang Qin Zhao Daming Feng Wei Zhang Zhaoqing Liu Tianyi Ma | 2020 | Nano-Micro Letters2020，12，10： | 2 |

| 6 | Phosphorylation of Rictor at Thr1135 impairs the Rictor/Cullin-1 complex to ubiquitinate SGK1显示文摘The Rictor/mTOR complex plays a pivotal role in a variety of cellular functions including cellular metabolism,cell proliferation and survival by phosphorylating Akt at Ser473 to fully activate the Akt kinase.However,its upstream regulatory pathways as well as whether it has additional function(s)remain largely unknown.We recently reported that Rictor contains a novel ubiquitin E3 ligase activity by forming a novel complex with Cullin-1,but not with other Cullin family members.Furthermore,we identified SGK1 as its downstream target.Interestingly,Rictor,but not Raptor or mTOR,promotes SGK1 ubiquitination.As a result,SGK1 expression is elevated in Rictor^(–/–)MEFs.We further defined that as a feedback mechanism,Rictor can be phosphorylated by multiple AGC family kinases including Akt,S6K and SGK1.Phosphorylation of Rictor at the Thr1135 site did not affect its kinase activity towards phosphorylating its conventional substrates including Akt and SGK1.On the other hand,it disrupted the interaction between Rictor and Cullin-1.Consequently,T1135E Rictor was defective in promoting SGK1 ubiquitination and destruction.This finding further expands our knowledge of Rictor’s function.Furthermore,our work also illustrates that Rictor E3 ligase activity could be governed by specific signaling kinase cascades,and that misregulation of this process might contribute to SGK overexpression which is frequently observed in various types of cancers. | Daming Gao Lixin Wan Wenyi Wei | 2010 | Protein & Cell2010，1，10： | 2 |

| 9 | Responses of Soil Bacterial Diversity to Fertilization are Driven by Local Environmental Context Across China显示文摘Soil microbial diversity is extremely vulnerable to fertilization,which is one of the main anthropogenic activities associated with global changes.Yet we know little about how and why soil microbial diversity responds to fertilization across contrasting local ecological contexts.This knowledge is fundamental for predicting changes in soil microbial diversity in response to ongoing global changes.We analyzed soils from ten 20-year field fertilization(organic and/or inorganic)experiments across China and found that the national-scale responses of soil bacterial diversity to fertilization are dependent on ecological context.In acidic soils from regions with high precipitation and soil fertility,inorganic fertilization can result in further acidification,resulting in negative impacts on soil bacterial diversity.In comparison,organic fer-tilization causes a smaller disturbance to soil bacterial diversity.Despite the overall role of environmental contexts in driving soil microbial diversity,a small group of bacterial taxa were found to respond to fer-tilization in a consistent way across contrasting regions throughout China.Taxa such as Nitrosospira and Nitrososphaera,which benefit from nitrogen fertilizer addition,as well as Chitinophagaceae,Bacilli,and phototrophic bacteria,which respond positively to organic fertilization,could be used as bioindicators for soil fertility in response to fertilization at the national scale.Overall,our work provides new insights into the importance of local environmental context in determining the responses of soil microbial diver-sity to fertilization,and identifies regions with acidic soils wherein soil microbial diversity is more vul-nerable to fertilization at the national scale. | Youzhi Feng Manuel Delgado-Baquerizo Yongguan Zhu Xiaozeng Han Xiaori Han Xiuli Xin Wei Li Zhibing Guo Tinghui Dang Chenhua Li Bo Zhu Zejiang Cai Daming Li Jiabao Zhang | 2022 | Engineering2022，8，5： | 1 |
| 10 | Identification of weathered troughs in granites for tunneling at Daya Bay reactor-neutrino experiment site显示文摘Weathered troughs are frequently encountered in granites.They can cause problems to tunneling in the rocks and have to be properly addressed.The structures or spatial shapes of weathered troughs were seldom clarified in the past.In this paper,four weathered troughs are identified by means of geophysical exploration,core drilling,logging,and in-situ stress measurement at Daya Bay reactor-neutrino experiment site in Shenzhen,China.The weathered troughs are exposed on the ground or partially covered by grass and soils,which will threaten the safety of horizontal tunneling at a shallow depth.High electrical resistivity(HER) method is adopted for its feasibility and practicality,in combination with field geological observation,ultrasonic televiewer in boreholes and in-situ stress measurement.By comparing the HER values of completely decomposed to fresh rocks,it is indicated that the HER values of weathered troughs in natural state are 0.4-100 ·m,and the in-situ stress is abnormally lower than those at upper and lower layers.Field investigations show that the depths of the four weathered troughs are 30-182 m,with bottom elevation over 10 m.The volume of each weathered trough is mostly over 1×10 6 m 3 in inverted conic form.The weathered troughs often occur in various kinds of landforms,such as ridges,gullies or gently dipping dish-like depression areas.Faults and boundaries of different granitic plutons as well as joints govern the formation,locations and strikes of these troughs under development. | Yanjun Shang Yongyue Shi Weijun Jin Daming Lin Fengbo Wu Wei Zhang | 2012 | Journal of Rock Mechanics and Geotechnical Engineering2012，4，2： | 1 |

| 14 | Arterial stimulation with simultaneous venous sampling for localizing insulinomas显示文摘Purpose: The present study aimed to assess the accuracies of arterial stimulation with simultaneous venous sampling(ASVS) in preoperative localization of insulinomas. Materials and Methods: A cohort consisting of 6 males and 14 females(median age, 48.5y; range, 28–62y) with pathologically proven insulinomas were included in this study. Selective angiographies were performed with the superior mesenteric artery(SMA), gastroduodenal artery(GDA), proximal splenic artery, and midsplenic artery in all individuals. Then ASVS procedures were followed after angiographies for these arteries. Clinical characteristics of the patient and the tumor number, location, and size were recorded. The accuracy of preoperative localization of insulinomas was tested. Results: A total of 22 tumors were identified by histopathological diagnosis. The mean size of the tumor was 1.40±0.60 cm. Five tumors were in the head/neck region and 17 in the body/tail region. ASVS accurately localized 17/20(85%) cases with only biochemical data and 19/20(95%) cases with biochemical data and angiography images. Variant pancreatic arterial anatomy was revealed in 2 false cases with inferior pancreatic artery replaced by the superior mesenteric artery. Conclusion: ASVS was highly accurate in localizing insulinomas and should be performed in most of the patients with suspected insulinomas before the operation. | Zhiyuan Wu Tingwei Su Daming Wu Xiaoyi Ding Zhongmin Wang Wei Huang Ziyin Wang Qin Liu Hua Zhang | 2018 | Journal of Interventional Medicine2018，1，1： | 1 |
| 15 | Science with the 2.5-meter Wide Field Survey Telescope(WFST)显示文摘The Wide Field Survey Telescope(WFST) is a dedicated photometric surveying facility being built jointly by University of Science and Technology of China(USTC) and the Purple Mountain Observatory(PMO). It is equipped with a 2.5-meter diameter primary mirror, an active optics system, and a mosaic CCD camera with 0.73 gigapixels on the primary focal plane for highquality image capture over a 6.5-square-degree field of view. The installation of WFST near the summit of Saishiteng mountain in the Lenghu region is scheduled in summer of 2023, and the operation is planned to start three months later. WFST will scan the northern sky in four optical bands(u, g, r and i) at cadences from hourly/daily in the deep high-cadence survey(DHS) program, to semi-weekly in the wide field survey(WFS) program. During a photometric night, a nominal 30 s exposure in the WFS program will reach a depth of 22.27, 23.32, 22.84, and 22.31(AB magnitudes) in these four bands, respectively, allowing for the detection of a tremendous amount of transients in the low-z universe and a systematic investigation of the variability of Galactic and extragalactic objects. In the DHS program, intranight 90 s exposures as deep as 23(u) and 24 mag(g), in combination with target of opportunity follow-ups, will provide a unique opportunity to explore energetic transients in demand for high sensitivities, including the electromagnetic counterparts of gravitational wave events, supernovae within a few hours of their explosions,tidal disruption events and fast, luminous optical transients even beyond redshift of unity. In addition, the final 6-year co-added images, anticipated to reach g■25.8 mag in WFS or 1.5 mags deeper in DHS, will be of fundamental importance to general Galactic and extragalactic science. The highly uniform legacy surveys of WFST will serve as an indispensable complement to those of the Vera C. Rubin Observatory's Legacy Survey of Space and Time(LSST) that monitors the southern sky. | Tinggui Wang Guilin Liu Zhenyi Cai Jinjun Geng Min Fang Haoning He Ji-an Jiang Ning Jiang Xu Kong Bin Li Ye Li Wentao Luo Zhizheng Pan Xuefeng Wu Ji Yang Jiming Yu Xianzhong Zheng Qingfeng Zhu Yi-Fu Cai Yuanyuan Chen Zhiwei Chen Zigao Dai Lulu Fan Yizhong Fan Wenjuan Fang Zhicheng He Lei Hu Maokai Hu Zhiping Jin Zhibo Jiang Guoliang Li Fan Li Xuzhi Li Runduo Liang Zheyu Lin Qingzhong Liu Wenhao Liu Zhengyan Liu Wei Liu Yao Liu Zheng Lou Han Qu Zhenfeng Sheng Jianchun Shi Yiping Shu Zhenbo Su Tianrui Sun Hongchi Wang Huiyuan Wang Jian Wang Junxian Wang Daming Wei Junjie Wei Yongquan Xue Jingzhi Yan Chao Yang Ye Yuan Yefei Yuan Hongxin Zhang Miaomiao Zhang Haibin Zhao Wen Zhao | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 1 |

| 18 | Evaluation of fiber degree for fish muscle based on the edge feature attention net显示文摘The fiber mouthfeel of fish muscle is a highly sought-after goal for surimi gel products.The primary aim of research and development has been to quickly and accurately evaluate fiber degree for fish muscle.Therefore,based on the ResNet model,edge feature attentional mechanism was introduced to obtain the edge feature attention net (EFANet) to evaluate fiber degree for fish muscle.The EFANet was trained and tested on a dataset,which was made by collecting microscopic pictures of fish samples with different degrees of breakage.Compared with the three classic convolutional neural network (CNN) models,the EFANet emphasizes the learning of fiber texture information for fish muscle,reduces the effect of image color change,and significantly improves the detection accuracy.The average accuracy and specificity of the EFANet-50 on the testing dataset were 96.22% and 97.92%,respectively,which proved that it can effectively predict the fiber degree of fish muscle. | Junhua Yu Jinlin Zhu Bowen Yan Xidong Jiao Jianlian Huang Jianxin Zhao Hao Zhang Wei Chen Daming Fan | 2022 | Food Bioscience2022，47，3： | 1 |
| 19 | Modification of diphenylamine-linked bis(oxazoline) ligands: Tuning of electronic effect and rigidity of ligand skeleton显示文摘The electronic effect of diphenylamine-linked bis(oxazoline) ligands was tuned through introduction of electron-withdrawing bromo and nitro substituents onto the 4 and 4′ position. The variation of the NH bond acidity was determined by the different chemical shifts of NH. The catalytic activity and enantioselectivity of the modified ligands were tested in the asymmetric Friedel-Crafts alkylation of indole with β-nitrostyrene. The effect of ligand skeleton rigidity was also investigated through the synthesis of iminodibenzyl-linked bis(oxazoline) ligands and evaluation of their catalytic activity in Friedel-Crafts alkylation. | LIU Han LI Wei DU DaMing | 2009 | Science China Chemistry2009，52，9： | 0 |
| 20 | Nanoengineering Metal–Organic Frameworks and Derivatives for Electrosynthesis of Ammonia显示文摘Electrocatalytic synthesis under mild conditions has become increasingly important as one of the practical alternatives for industrial applications,especially for the green ammonia(NH_(3))industry.A properly engineered electrocatalyst plays a vital role in the realization of superior catalytic performance.Among various types of promising nanomaterials,metal–organic frameworks(MOFs)are competitive candidates for developing efficient electrocatalytic NH_(3) synthesis from simple nitrogen-containing molecules or ions,such as N_(2) and NO_(3)^(−).In this review,recent advances in the development of electrocatalysts derived from MOFs for the electrosynthesis of NH_(3) are collected,categorized,and discussed,including their application in the N_(2) reduction reaction(NRR)and the NO_(3)^(−)reduction reaction(NO3RR).Firstly,the fundamental principles are illustrated,such as plausible mechanisms of NH_(3) generation from N_(2) and NO_(3)^(−),the apparatus of corresponding electrocatalysis,parameters for evaluation of reaction efficiency,and detection methods of yielding NH_(3).Then,the electrocatalysts for NRR processes are discussed in detail,including pristine MOFs,MOF-hybrids,MOF-derived N-doped porous carbons,single atomic catalysts from pyrolysis of MOFs,and other MOF-related materials.Subsequently,MOF-related NO3RR processes are also listed and discussed.Finally,the existing challenges and prospects for the rational design and fabrication of electrocatalysts from MOFs for electrochemical NH_(3) synthesis are presented,such as the evolution of investigation methods with artificial intelligence,innovation in synthetic methods of MOF-related catalysts,advancement of characterization techniques,and extended electrocatalytic reactions. | Daming Feng Lixue Zhou Timothy J.White Anthony K.Cheetham Tianyi Ma Fengxia Wei | 2023 | Nano-Micro Letters2023，15，11： | 0 |
