| 1 | Synthesis of Alumina-Coated Natural Graphite for Highly Cycling Stability and Safety of Li-Ion Batteries显示文摘The natural graphite(NG)urdformly coated with alumina ceramics(Al2O3)was successfully synthesized through sol-gel method.The aluminum plastic film soft-packed battery prepared using Al2O3-coated NG as anode material exhibits excellent cycle performance and safety performance.The cycling retention of AN-1 is 84.95% after 200 cycles at a rate of 1 C in a potential window ranging from 3.0 to 4.35 V,which is much greater than 75.07% of NG under the same test conditions.The result of the nail penetration tests shows that the successful nail penetration rate of the NG used as anode is 0%,while that of Al2O3 coated samples AN-1 is 100%.The test results show that the Al2O3 coating could act as a solid electrolyte to suppress side reactions,improve cycle stability,and prevent a thermal runaway under mechanical abuse. | Tao Xu Chengkun Zhou Haihui Zhou Zekun Wang Jianguo Ren | 2019 | Chinese Journal of Chemistry2019，37，4： | 13 |
| 2 | Monthly survey of N-nitrosamine yield in a conventional water treatment plant in North China显示文摘A sampling campaign was conducted monthly to investigate the occurrence of N-nitrosamines at a conventional water treatment plant in one city in North China.The yield of N-nitrosamines in the treated water indicated precursors changed greatly after the source water switching.Average concentrations of N-nitrosodimethylamine(NDMA),N-nitrosomorpholine(NMOR),and N-nitrosopyrrolidine(NPYR) in the finished water were6.9,3.3,and 3.1 ng/L,respectively,from June to October when the Luan River water was used as source water,while those of NDMA,N-nitrosomethylethylamine(NMEA),and NPYR in the finished water were 10.1,4.9,and 4.7 ng/L,respectively,from November to next April when the Yellow River was used.NDMA concentration in the finished water was frequently over the 10 ng/L,i.e.,the notification level of California,USA,which indicated a considerable threat to public health.Weak correlations were observed between N-nitrosamine yield and typical water quality parameters except for the dissolved organic nitrogen. | Chengkun Wang Shuming Liu Jun Wang Xiaojian Zhang Chao Chen | 2015 | Journal of Environmental Sciences2015，27，12： | 11 |

| 4 | A micro-adjusting attitude mechanism for autonomous drilling robot end-effector显示文摘Drilling end-effector is a key unit in autonomous drilling robot.The perpendicularity of the hole has an important influence on the quality of airplane assembly.Aiming at the robot drilling perpendicularity,a micro-adjusting attitude mechanism and a surface normal measurement algorithm are proposed in this paper.In the mechanism,two rounded eccentric discs are used and the small one is embedded in the big one,which makes the drill’s point static when adjusting the drill’s attitude.Thus,removal of drill’s point position after adjusting the drill attitude can be avoided.Before the micro-adjusting progress,four non-coplanar points in space are used to determine a unique sphere.The normal at the drilling point is measured by four laser ranging sensors.The adjusting angles at which the motors should be rotated to adjust attitude can be calculated by using the deviation between the normal and the drill axis.Finally,the motors will drive the two eccentric discs to achieve micro-adjusting progress.Experiments on drilling robot system and the results demonstrate that the adjusting mechanism and the algorithm for surface normal measurement are effective with high accuracy and efficiency. | YUAN PeiJiang WANG QiShen SHI ZhenYun WANG TianMiao WANG ChengKun CHEN DongDong SHEN LiHeng | 2014 | Science China(Information Sciences)2014，57，12： | 8 |

| 6 | Characterization of dissolved organic matter as N-nitrosamine precursors based on hydrophobicity, molecular weight and fluorescence显示文摘It is very important to identify the dominant precursors for N-nitrosamine formation from bulk organic matter, to enhance the understanding of N-nitrosamine formation pathways in water treatment plants and allow the development of practical treatment technologies. In this study, dissolved organic matter (DOM) from two source waters was fractionated with XAD resins and ultra- filtration membranes. The N-nitrosamine formation potential (FP) (ng of N-nitrosamines formed per mg of dissolved organic carbon (DOC)) from raw water and each fraction were measured and correlated with the fluorescence excitation-emission matrix (EEM), molecular weight (MW) and other assays. The results showed that the hydrophilic fraction had N-nitrosamine FP 1.3 to 3.5 times higher than the hydrophobic fraction from both source waters. The DOM fraction with low MW was the dominant fraction in these two source waters and contributed more precursors for N-nitrosamine formation than the larger MW fraction. The EEM spectra indicated there were notable amounts of soluble microbial products (SMPs) and aromatic proteins in the two studied rivers, which probably originated from wastewater discharge. The SMPs tended to be more closely correlated with N-nitrosodimethylamine formation potential than the other DOM components. Higher N-nitrosamine FP were also related to fractions with lower DOC/DON ratios and lower SUVA 254 values. | Chengkun Wang Xiaojian Zhang Jun Wang Chao Chen | 2013 | Journal of Environmental Sciences2013，25，1： | 5 |
| 7 | A Novel Strategy to Fabricate Core-Sheath Structure Piezoelectric Yarns for Wearable Energy Harvesters显示文摘Wearable and portable electronic devices based on textile structure have been widely used owing to their wearability and comfortableness.However,yarn fineness and the comfort of the fabric cannot satisfy the requirements of smart wearable devices.This work presents a novel strategy to prepare highly integrated PVDF/conductive nylon core-sheath structure piezoelectric yarns for wearable which is fabricated by combining electrospinning strategy with 2D braiding technology.The fineness of single yarns as well as strength are both improved significantly compared to previous works.The piezoelectric outputs of the yarn are still stable after 800 s fatigue test at a frequency of 4 Hz,and the cycle stability can maintain more than 3200 cycles.Furthermore,the piezoelectric yarns are further woven into piezoelectric plain fabric.According to the electrical performance,the length of the piezoelectric yarn and the thickness of the piezoelectric layer would both affect the output electrical performance.The yarn of the 10 cm in length and 600μm in fineness can produce an output voltage of 120 mV.Meanwhile,Both the piezoelectric yarn and the fabric could generate piezoelectric output signals through human movement,such as bending,walking.Therefore,the electrical and mechanical performance of the piezoelectric yarns prepared in our work could be improved significantly,and the comfortableness and durability performance of the piezoelectric fabric can satisfy most wearing requirements,which would provide some help in the field of piezoelectric wearable devices based on yarns and fabrics. | Lili Xue Wei Fan Yang Yu Kai Dong Chengkun Liu Yanli Sun Cong Zhang Weichun Chen Ruixin Lei Kai Rong Qi Wang | 2021 | Advanced Fiber Materials2021，3，4： | 3 |
| 8 | Evidence combination method in time domain based on reliability and importance显示文摘In order to achieve the information fusion in the time domain based on the evidence theory, an evidence combination method in the time domain based on reliability and importance is proposed according to the idea of evidence discount. Firstly, the distortion of the time-domain evidence is judged based on single exponential smoothing. The real-time reliability of the evidence at the adjacent time is obtained by the real-time reliability assessment method of the evidence based on the credibility decay model.Then, the relative importance of the evidence at the adjacent time is obtained by comprehensively considering improved conflict degree and uncertainty. Finally, based on the criterion of evidence discount and the Dempster's rule of combination, the evidence combination is carried out to achieve the sequential combination of time-domain evidence. The numerical simulation and analysis show that this method has fully embodied the dynamic characteristics of time-domain evidence combination, and it has strong processing ability for conflict information and anti-disturbing ability.The proposed method has good applicability to information fusion in the time domain. | LUO Chengkun CHEN Yunxiang XIANG Huachun WANG Weijia WANG Zezhou | 2018 | Journal of Systems Engineering and Electronics2018，29，6： | 2 |

| 10 | Longwall mining under gateroads and gobs of abandoned small mine显示文摘Due to the use of outdated mining technology or room and pillar mining process in small coal mines, the coal recovery ratio is only 10–25%. In many regions of China, the damage area caused by the small coal mines amounted to nearly one hundred square kilometers. Therefore, special mining techniques must be taken to reclaim the wasted resource in disturbed coal areas. This paper focuses on the different mining methods by analyzing the longwall panel layout and abandoned gateroad(AG) distribution in the abandoned area of Cuijiazhai coal mine in northwestern China. On the basis of three-dimensional geological model, FLAC3 D numerical simulation was employed. The abutment pressure distribution was simulated when the panel face passed through the disturbed areas. The proper angle of the inclined face was analyzed when the panel face passed through the abandoned gateroads. The results show that the head end of the face should be 13–20 m ahead of the tail end. The pillars on both sides of abandoned gateroads had not been damaged at the same time, and no large-area stress concentration occured above the main roof.Therefore, the coal reserves of disturbed areas can be successfully recovered by using underground longwall mining. | Li Yang Zhu Enguang Zhang Kangning Li Minghao Wang Jiaxing Li Chengkun | 2017 | International Journal of Mining Science and Technology2017，27，1： | 1 |

| 12 | Establishment of the GPS Monitoring Network in North China, the Relation of Horizontal Crustal Movement to Stress Field and Seismicity显示文摘In the paper, the establishment, measurement, data-processing program and monitoring accuracy of the GPS seismic monitoring network in North China, especially in the Capital-Circle area, have been presented briefly. The relation of horizontal crustal deformation to tectonic movement, stress-field variation and seismicity has been analyzed in detail. The results indicate that the accuracy of GPS measurement has reached the order of 10-9 and the annual rate of horizontal crustal deformation in North China is about 4 ~5 mm. Horizontal crustal movement is a direct indication of the regional stress field. Therefore, by monitoring the time-sequence variation of horizontal crustal motion, it would be possible to investigate the change in the stress field, to analyze the tendency of seismicity and to determine the seismogenic zones. | Li Yanxing, Hu Xinkang, Zhao Chengkun, Wang Min, Guo Liangqian, and Xu JushengFirst Crustal Deformation Monitoring Center, China Seismological Bureau, Tianjin 300180, China Institute of Seismology, China Seismological Bureau, Wuhan 430071, China | 1998 | Earthquake Research in China1998，12，4： | 1 |
| 13 | Structural insights into the membrane microdomain organization by SPFH family proteins显示文摘The lateral segregation of membrane constituents into functional microdomains,conceptually known as lipid raft,is a universal organization principle for cellular membranes in both prokaryotes and eukaryotes.The widespread Stomatin,Prohibitin,Flotillin,and HflK/C(SPFH)family proteins are enriched in functional membrane microdomains at various subcellular locations,and therefore were hypothesized to play a scaffolding role in microdomain formation.In addition,many SPFH proteins are also implicated in highly specific processes occurring on the membrane.However,none of these functions is understood at the molecular level.Here we report the structure of a supramolecular complex that is isolated from bacterial membrane microdomains and contains two SPFH proteins(HflK and HflC)and a membrane-anchored AAA+protease FtsH.HflK and HflC form a circular 24-mer assembly,featuring a laterally segregated membrane microdomain(20 nm in diameter)bordered by transmembrane domains of HflK/C and a completely sealed periplasmic vault.Four FtsH hexamers are embedded inside this microdomain through interactions with the inner surface of the vault.These observations provide a mechanistic explanation for the role of HflK/C and their mitochondrial homologs prohibitins in regulating membrane-bound AAA+proteases,and suggest a general model for the organization and functionalization of membrane microdomains by SPFH proteins. | Chengying Ma Chengkun Wang Dingyi Luo Lu Yan Wenxian Yang Ningning Li Ning Gao | 2022 | Cell Research2022，32，2： | 0 |

In this paper,Sn-doped Ga_(2)O_(3) films were prepared on a sapphire substrate by radio frequency magnetron sputtering. The films were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and ultraviolet visible spectroscopy, and the effect of annealing atmosphere on the properties of films was studied. The Ga_(2)O_(3) films changed from amorphous to β-Ga_(2)O_(3) after annealing at 900 °C. The films were composed of micro crystalline particles with a diameter of about 5–20 nm.The β-Ga_(2)O_(3) had high transmittance for wavelengths above 300 nm, and obvious absorption for solar-blind signals at 200–280 nm.The metal semiconductor metal type solar-blind detectors were prepared. The detector based on Sn-doped β-Ga_(2)O_(3) thin film annealed in N_2 has the best response performance to 254 nm light. The photo-current is 10 μA at 20 V, the dark-current is 5.76 pA,the photo dark current ratio is 1.7 × 10~6, the response rate is 12.47 A/W, the external quantum efficiency is 6.09 × 10~3%, the specific detection rate is 2.61 × 10~(12) Jones, the response time and recovery time are 378 and 90 ms, respectively. | Lijun Li Chengkun Li Shaoqing Wang Qin Lu Yifan Jia Haifeng Chen | 2023 | Journal of Semiconductors2023，44，6： | 0 |
| 15 | Tailoring light on three-dimensional photonic chips: a platform for versatile OAM mode optical interconnects显示文摘Explosive growth in demand for data traffic has prompted exploration of the spatial dimension of lightwaves, which provides a degree of freedom to expand data transmission capacity. Various techniques basedon bulky optical devices have been proposed to tailor light waves in the spatial dimension. However, theirinherent large size, extra loss, and precise alignment requirements make these techniques relativelydifficult to implement in a compact and flexible way. In contrast, three-dimensional (3D) photonic chips withcompact size and low loss provide a promising miniaturized candidate for tailoring light in the spatialdimension. Significantly, they are attractive for chip-assisted short-distance spatial mode optical interconnectsthat are challenging to bulky optics. Here, we propose and fabricate femtosecond laser-inscribed 3D photonicchips to tailor orbital angular momentum (OAM) modes in the spatial dimension. Various functions on theplatform of 3D photonic chips are experimentally demonstrated, including the generation, (de)multiplexing,and exchange of OAM modes. Moreover, chip-chip and chip–fiber–chip short-distance optical interconnectsusing OAM modes are demonstrated in the experiment with favorable performance. This work paves the wayto flexibly tailor light waves on 3D photonic chips and offers a compact solution for versatile opticalinterconnects and other emerging applications with spatial modes. | Jue Wang Chengkun Cai Feng Cui Min Yang Yize Liang Jian Wang | 2023 | Advanced Photonics2023，5，3： | 0 |

| 17 | Pt-confinement catalyst with dendritic hierarchical pores on excellent sulfur-resistance for hydrodesulfurization of dibenzothiophene and 4,6-dimethyldibenzothiophene显示文摘Metal confinement catalyst Mo S_(2)/Pt@TD-6%Ti(TD,TS-1/Dendritic mesoporous silica nanoparticles composite) in dendritic hierarchical pore structures was synthesized and showed excellent sulfur-resistance performance and stabilities in catalytic hydrodesulfurization reactions of probe sulfide molecules.The Mo S_(2)/Pt@TD-6%Ti catalyst combines the concepts of Pt-confinement effect and hydrogen spillover of Pt noble metal.The modified micropores of Mo/Pt@TD-6%Ti only allow the migration and dissociation of small H_(2) molecules(0.289 nm),and effectively keep the sulfur-containing compounds(e.g.H_(2)S,0.362 nm) outside.Thus,the Mo S_(2)/Pt@TD-6%Ti catalyst exhibits higher DBT and 4,6-DMDBT HDS activities because of the synergistic effect of the strong H_(2) dissociation ability of Pt and desulfurization ability of Mo S_(2) with a lower catalyst cost.This new concept combining H2dissociation performance of noble metal catalyst with the desulfurization ability of transition metal sulfide Mo S_(2) can protect the noble metal catalyst avoiding deactivation and poison,and finally guarantee the higher activities for DBT and 4,6-DMDBT HDS. | Xilong Wang Chengkun Xiao Mohnnad H.Alabsi Peng Zheng Zhengkai Cao Jinlin Mei Yu Shi Aijun Duan Daowei Gao Kuo-Wei Huang Chunming Xu | 2022 | Green Energy & Environment2022，7，2： | 0 |
| 18 | Community participation in the management of wetland nature reserve:a case study of Nanjishan Nature Reserve, Jiangxi, China显示文摘In recent years, more and more conflicts have emerged in the management of nature reserves, of which themain problem is that how to carry out the campaign of conservation along with the promotion of development of localeconomics. To resolve the actual problem in Nanjishan National Wetland Nature Reserve and explore the idiographicmethod of the management of the wetland reserve, some studying methods including face-to-face interviews, informaldiscussion with local leaders and officials, group discussion with local fishers, questionnaire, and job of the conversationstation have been carried out. The results show that the education level of the local people is low; only 5% of the localpeople have an opportunity to the junior college; the main income of the local people is fishing, which accounts for 70%more or less; and the income is coming down year by year because of the unreasonable way of fishing. To cope with theproblems, some reformative way of management and the development of the reserve are introduced, such as establishingan NOG that constitutes of local fishermen to achieve the goal of community co-management, developing Bed andBreakfast and so on. Through practice of the management of the participation of the local people, we draw the conclusionthat the local people have a great desire to improve their life level, and to make the co-management of the reserve easy,it is important for the managers to play the role of pilot including engrafting the new ideas, giving some subsidy toencourage the local people to take part in the management. In addition, making local people perceive value of the reserveand the close relation between reserve conservation and the promotion of level of their life. On this basis, they incline totake part in the management of the reserve. | Wang Chengkun Liu Jingling | 2007 | Ecological Economy2007，3，3： | 0 |
| 19 | Comparison of intestinal absorption characteristics between rhubarb traditional Chinese medicine preparation and activity ingredients using in situ and in vitro model显示文摘Objective: The intestinal absorption characteristics of active ingredients are very important for oral administration of traditional Chinese medicine(TCM) to achieve the desired therapeutic effect.However, a deeper understanding about active ingredients absorption characteristics is still lack. The aim of this study was to investigate the absorption properties and mechanism of rhubarb active ingredients in TCM preparation and pure form.Methods: The intestinal absorption behavior of active ingredients in Shenkang extract(SKE) and rhubarb anthraquinone ingredients(RAI) were investigated by in situ single-pass intestinal perfusion model. And the bidirectional transport characteristics of these active ingredients were assessed by in vitro Caco-2 cell monolayer model.Results: In situ experiment on Sprague-Dawley rats, the effective permeability coefficient values of aloeemodin, emodin and chrysophanol in RAI were higher than those in SKE, and the value of rhein in RAI was lower than that in SKE. But the easily absorbed segments of intestine were consistent for all ingredients,whether in SKE or in RAI. In vitro experiment, the apparent permeability coefficient values of rhein, emodin and chrysophanol in RAI were higher than those in SKE, and this value of aloe-emodin in RAI was lower than that in SKE. But their efflux ratio(ER) values in SKE and RAI were all similar.Conclusion: Four rhubarb anthraquinone ingredients in SKE and RAI have similar absorption mechanism and different absorption behavior, and the microenvironment of the study models influenced their absorption behavior. The results may provide an aid for understanding of the absorption characteristics of the TCM active ingredients in complex environments and the complementarities of different research models. | Wenjing Ta Xiaoying Yang Jie Wang Chengkun Han Ruochen Hua Wen Lu | 2023 | Chinese Herbal Medicines2023，15，1： | 0 |
| 20 | New approach for uncertain random multi-objective programming problems based on C_(ESD) criterion显示文摘To overcome the defects that the traditional ap-proach for multi-objective programming under uncertain ran-dom environment(URMOP)neglects the randomness and uncer-tainty of the problem and the volatility of the results,a new ap-proach is proposed based on expected value-standard devi-ation value criterion(C_(ESD) criterion).Firstly,the effective solution to the URMOP problem is defined;then,by applying sequence relationship between the uncertain random variables,the UR-MOP problem is transformed into a single-objective program-ming(SOP)under uncertain random environment(URSOP),which are transformed into a deterministic counterpart based on the C_(ESD) criterion.Then the validity of the new approach is proved that the optimal solution to the SOP problem is also effi-cient for the URMOP problem;finally,a numerical example and a case application are presented to show the effectiveness of the new approach. | SUN Yun WANG Ying MENG Xiangfei FU Chaoqi LUO Chengkun | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 0 |
