| 1 | Bio-replicated forming of the biomimetic drag-reducing surfaces in large area based on shark skin显示文摘On the investigation of biomimetic drag-reducing surface, direct replication of the firm scarfskins on low-resistance creatures to form biomimetic drag-reducing surfaces with relatively vivid morphology relative to the living prototype is a new attempt of the bio-replicated forming technology.Taking shark skin as the bio-replication template, the hot embossing method was applied to the microreplication of its outward morphology. Furthermore, the skins were jointed together to form the drag-reducing surface in large area. The results of the resistance measurements in a water tunnel according to the flat-plate sample pieces have shown that the biomimetic shark-skin coating fabricated by the bio-replicated forming method has significant drag reduction effect, and that the drag reduction efficiency reached 8.25% in the test conditions. | HAN Xin ZHANG DeYuan LI Xiang LI YuanYue | 2008 | Chinese Science Bulletin2008，53，10： | 16 |

| 3 | High-precision bio-replication of synthetic drag reduction shark skin显示文摘Nano-long chains were grafted over the replicated micro-grooves of shark skin in a novel attempt to replicate bio-synthetic drag reduction structure with high precision through synthetic bio-replication. Pre-treated shark skin was used as casting template to prepare a flexible female die of silicone rubber by soft die formation. A waterborne epoxy resin was then used to graft long-chains of drag reduction agent and prepare a synthetic drag reduction shark skin with nano-long chain drag reduction interface and lifelike micro-grooves. Replication precision analysis shows that this technology could replicate the complicated three-dimensional morphology of a biological drag reduction surface with high precision. Drag reduction experiments show that the material had an excellent synthetic drag reduction effect, with a maximal drag reduction rate of up to 24.6% over the velocities tested. | ZHANG DeYuan LI YuanYue HAN Xin LI Xiang CHEN HuaWei | 2011 | Chinese Science Bulletin2011，56，9： | 13 |
| 4 | Quantitative prediction of mining subsidence and its impact on the environment显示文摘This study is focused on the prediction of mining subsidence and its impact on the environment in the Hongqi mining area. The study was carried out by means of a probability integral model based, in first instance based on field surveys and the analysis of data collected from this area. Isolines of mining subsidence were then drawn and the impact caused by mining subsidence on the environment was analyzed quantitatively by spatial analysis with Geographic Information System (GIS). The results indicate that the subsidence area of the first working-mine can be as large as 2.54 km 2 , the maximum subsidence is 3440 mm which will cause 1524 houses to be relocated. The entire subsidence area of the mine can reach 8.09 km 2 , with a maximum subsidence of 3590 mm. Under these circumstances the value of the loss of ecosystem services will reach 5.371 million Yuan and the cost of relocating buildings will increase to 6.858 million Yuan. | Jianjun Song Chunjian Han Ping Li Junwei Zhang Deyuan Liu Minde Jiang Lin Zheng Jingkai Zhang Jianying Song | 2012 | International Journal of Mining Science and Technology2012，22，1： | 13 |
| 5 | Study on the micro-replication of shark skin显示文摘Direct replication of creatural scarfskins to form biomimetic surfaces with relatively vivid morphology is a new attempt of the bio-replicated forming technology at animal body. Taking shark skins as the replication templates, and the micro-embossing and micro-molding as the material forming methods, the micro-replicating technology of the outward morphology on shark skins was demonstrated. The preliminary analysis on replication precision indicates that the bio-replicated forming technology can replicate the outward morphology of the shark scales with good precision, which validates the application of the bio-replicated forming technology in the direct morphology replication of the firm creatural scarfskins. | HAN Xin ZHANG DeYuan | 2008 | Science China(Technological Sciences)2008，51，7： | 12 |

| 7 | Magnetization of microorganism cells by sol-gel method显示文摘Microorganism cells could be used as templates during fabrication of magnetic or conductive microstructures in different standard shapes. In this paper, feasibility of magnetizing microorganism cells by sol-gel method, which is to coat cells of Spirulina (a type of natural micro-helical microorganism) with the ferrite (a kind of magnetic material), was discussed and investigated. Then the cell form, components and the phase structure were observed and analyzed using various tools including optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray detector (EDX), transmission electron microscopy (TEM), and X-ray diffraction analysis (XRD). Results showed that spirulina cells could be coated with ferrite after the sol-gel process, with the shape of natural helixes well kept, that the components of different sampling points on the surface layer were consistent and the thickness of layer was uniform, and that the type of the surface ferrite layer formed was cubic Fe3O4. It was also observed that there were nano-particles yielded in the cells and certain deposit on the walls between cells. The kinetics of the cell magnetization technology by sol-gel was also discussed. | CHEN Bo ZHAN TianZhuo LIAN ZhiYang ZHANG DeYuan | 2008 | Science China(Technological Sciences)2008，51，5： | 11 |
| 8 | A deep seismic sounding profile across the Tianshan Mountains显示文摘The deep seismic sounding profile across the Tianshan Mountains revealed a two-layer crustal structure in the Tianshan region, namely the lower and upper crusts. Lateral variations of layer velocity and thickness are evidently shown. Low-velocity layers spread discontinuously at the bottom of the upper crust. The Mono depth is 47 km in the Kuytun area and 50 km in the Xayar area. In the Tianshan Mountains, the Moho becomes deeper with the maximum depth of 62 km around the boundary between the southern and northern Tianshan Mountains. The average velocity ranges from 6.1 to 6.3 km/s in the crust and 8.15 km/s at the top of the upper mantle. Two groups of reliable reflective seismic phases of the Moho (Pm1 and Pm2) are recognized on the shot record section of the Kuytun area. A staked and offset region, 20-30 km long, is displayed within a shot-geophone distance of 190-210 km in Pm1 and Pm2. Calculation shows that the Moho is offset by 10 km in the northern Tianshan region, 62 km deep in the south while | LU Deyuan LI Qiusheng GAO Rui LI Yingkang LI Dexing LIU Wen ZHANG Zhiying | 2000 | Chinese Science Bulletin2000，45，22： | 9 |

| 11 | Microwave Absorption and Shielding Property of Composites with FeSiAl and Carbonous Materials as Filler显示文摘Silicone rubber composites filled with FeSiAl alloys and multi-walled carbon nanotubes(MWCNT)/graphite have been prepared for the first time by a coating process.The complex permittivity and permeability of the composites were measured with a vector network analyzer in a 1-4 GHz frequency range,and the DC electric conductivity was measured by a standard four-point contact method.These parameters were then used to calculate the reflection loss(RL) and shielding effectiveness(SE) of the composites.The results showed that the added MWCNT increased the permittivity and permeability of composites in the L-band,while the added graphite increased only the permittivity.The variation lies in the interactions between two carbonous absorbents.Addition of 1 wt% MWCNT enhanced the RL in the L-band(minimum 5.7 dB at 1 mm,7.3 dB at 1.5 mm),while the addition of graphite did not.Addition of MWCNT as well as graphite reinforced the shielding property of the composites(maximum SE 13.3 dB at 1 mm,18.3 dB at 1.5 mm) owing to the increase of conductivity.The addition of these carbonous materials could hold the promise of enforcing the absorption and shielding property of the absorbers. | Wenqiang Zhang Yonggang Xu Liming Yuan Jun Cai Deyuan Zhang | 2012 | Journal of Materials Science & Technology2012，28，10： | 8 |

| 13 | Effects of Multi-walled Carbon Nanotubes on the Electromagnetic Absorbing Characteristics of Composites Filled with Carbonyl Iron Particles显示文摘The electromagnetic(EM) wave absorbing property of silicone rubber filled with carbonyl iron particles(CIPs) and multi-walled carbon nanotubes(MWCNTs) was examined.Absorbents including MWCNTs and spherical/flaky CIPs were added to silicone rubber using a two-roll mixer.The complex permittivity and complex permeability were measured over the frequency range of 1-18 GHz.The two EM parameters were verified and the uniform dispersion of MWCNTs and CIPs was confirmed by comparing the measured reflection loss(RL) with the calculated one.As the MWCNT weight percent increased,the RL of the spherical CIPs/silicone rubber composites changed insignificantly.It was attributed to the random distribution of spherical CIPs and less content of MWCNTs.On the contrary,for composites filled with flaky CIPs the absorption bandwidth increased at thickness 0.5 mm(RL value lower than-5 dB in 8-18 GHz) and the absorption ratio increased at lower frequency(minimum-35 dB at 3.5 GHz).This effect was attributed to the oriented distribution of flaky CIPs caused by interactions between the two absorbents.Therefore,mixing MWCNTs and flaky CIPs could achieve wider-band and higher-absorption ratio absorbing materials. | Yonggang Xu Deyuan Zhang Jun Cai Liming Yuan Wenqiang Zhang | 2012 | Journal of Materials Science & Technology2012，28，1： | 7 |
| 14 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022，15，9： | 6 |
| 15 | Chatter stability and precision during high-speed ultrasonic vibration cutting of a thin-walled titanium cylinder显示文摘Titanium alloys are widely used in the aviation and aerospace industries due to their unique mechanical and physical properties.Specifically,thin-walled titanium(Ti)cylinders have received increasing attention for their applications as rocket engine casings,aircraft landing gear,and aero-engine hollow shaft due to their observed improvement in the thrust-to-weight ratio.However,the conventional cutting(CC)process is not appropriate for thin-walled Ti cylinders due to its low thermal conductivity,high strength,and low stiffness.Instead,high-speed ultrasonic vibration cutting(HUVC)assisted processing has recently proved highly effective for Ti-alloy machining.In this study,HUVC technology is employed to perform external turning of a thinwalled Ti cylinder,which represents a new application of HUVC.First,the kinematics,tool path,and dynamic cutting thickness of HUVC are evaluated.Second,the phenomenon of mode-coupling chatter is analyzed to determine the effects and mechanism of HUVC by establishing a critical cutting thickness model.HUVC can increase the critical cutting thickness and effectively reduce the average cutting force,thus reducing the energy intake of the system.Finally,comparison experiments are conducted between HUVC and CC processes.The results indicate that the diameter error rate is 10%or less for HUVC and 51%for the CC method due to a 40%reduction in the cutting force.In addition,higher machining precision and better surface roughness are achieved during thin-walled Ti cylinder manufacturing using HUVC. | Zhenlong PENG Deyuan ZHANG Xiangyu ZHANG | 2020 | Chinese Journal of Aeronautics2020，33，12： | 6 |
| 16 | Magnetization of microorganism cells by thermal decomposition method显示文摘The bio-limited forming technology, a new technology organically integrating microbiology, manufacturing science and materials science, is used in the manufacturing of magnetic or conductive microstructures of different standard shapes. This paper explores the feasibility of magnetizing microorganism with thermal decomposition method. The principle of thermal decomposition of iron pentacarbonyl has been adopted to investigate the cells of Spirulina (a type of nature micro-helical microorganism) coated with pure iron. Further analysis have been conducted on the observations results of hollow micro-helical magnetic particles form, components and the phase structure obtained by using various tools including optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray detector (EDX), transmission electron microscopy (TEM), and X-ray diffraction analysis (XRD). Results showed that Spirulina cells could be coated with iron particles after the completion of thermal decomposition process, with well-kept shape of natural helixes and consistent components of different sampling points on the surface layer and thickness of layer. After the heat treatment at 700°C, the type of the surface iron layer formed was α-Fe. The paper also investigates the kinetics of the cell magnetization technology by thermal decomposition. | ZHANG DeYuan ZHANG WenQiang CAI Jun | 2011 | Science China(Technological Sciences)2011，54，5： | 5 |

| 19 | In vivo degradation and endothelialization of an iron bioresorbable scaffold显示文摘Detection of in vivo biodegradation is critical for development of next-generation medical devices such as bioresorbable stents or scaffolds(BRSs).In particular,it is urgent to establish a nondestructive approach to examine in vivo degradation of a new-generation coronary stent for interventional treatment based on mammal experiments;otherwise it is not available to semi-quantitatively monitor biodegradation in any clinical trial.Herein,we put forward a semi-quantitative approach to measure degradation of a sirolimus-eluting iron bioresorbable scaffold(IBS)based on optical coherence tomography(OCT)images;this approach was confirmed to be consistent with the present weight-loss measurements,which is,however,a destructive approach.The IBS was fabricated by a metal-polymer composite technique with a polylactide coating on an iron stent.The efficacy as a coronary stent of this new bioresorbable scaffold was compared with that of a permanent metal stent with the name of trade mark Xience,which has been widely used in clinic.The endothelial coverage on IBS was found to be greater than on Xience after implantation in a rabbit model;and our well-designed ultrathin stent exhibited less individual variation.We further examined degradation of the IBSs in both minipig coronary artery and rabbit abdominal aorta models.The present result indicated much faster iron degradation of IBS in the rabbit model than in the porcine model.The semi-quantitative approach to detect biodegradation of IBS and the finding of the species difference might be stimulating for fundamental investigation of biodegradable implants and clinical translation of the next-generation coronary stents. | Wenjiao Lin Hongjie Zhang Wanqian Zhang Haiping Qi Gui Zhang Jie Qian Xin Li Li Qin Haifeng Li Xiang Wang Hong Qiu Xiaoli Shi Wei Zheng Deyuan Zhang Runlin Gao Jiandong Ding | 2021 | Bioactive Materials2021，6，4： | 3 |
| 20 | Research on magnetic metallization of microorganism cells using electroplating technique显示文摘Spirulina platensis were chosen as templates to produce microscopic helical soft-core magnetic particles by way of depositing ferromagnetic alloy onto their surface using electroplating technique,and the process of electroplating ferromagnetic alloy onto microorganism cells was studied.The morphology and appearance of the coated Spirulina platensis were analyzed with optical microscopy and scanning electron microscopy,respectively,and the ingredients and phase structure of the alloy coating were analyzed with energy dispersive X-ray detector(EDX) and X-ray diffractive analysis(XRD),respectively.The result showed that the particles were successfully coated with uniform metal coating and their initial helical shape was perfectly replicated.The coating was NiFe alloy,and its phase structure was face-centered cubic structure.The magnetic properties of the coated particles were tested with vibrating sample magnetometer(VSM),and the result showed that the particles were ferro-magnetic,which means the magnetic electroplating of the microorganism cells was successfully achieved.The electrochemical reaction mechanism of the magnetic plating process was also analyzed;the result showed that the deposition of NiFe on the microorganism cells was anomalous codeposition,and that Fe2+ ion was preferential deposited when magnetic stirring was applied. | CAI Jun ZHANG DeYuan LAN MingMing LIAN ZhiYang | 2011 | Science China(Technological Sciences)2011，54，6： | 3 |
