| 1 | A review of the large-scale production of carbon nanotubes:The practice of nanoscale process engineering显示文摘Carbon nanotubes(CNTs) are nanomaterials that have attracted great research interest because of their unique properties and promising applications.The controllable synthesis of CNTs is a precondition for their broad application.In this review,we consider nanoscale process engineering and assess recent progress in the mass production of ultra-long,inexpensive CNTs with good alignment as well as tunability in wall number and diameter for fundamental and engineering science applications across multiple scales.Cutting-edge nanoscale process engineering research in the areas of physics,chemistry,materials,engineering,ecology,and social science will allow us to obtain high added value and multi-functional advanced CNTs.The synthesis of CNTs with controllable chirality,good-alignment,and predetermined sizes and lengths still presents great challenges.Through multidisciplinary scientific research,advanced CNT-based materials will promote the development of a sustainable society. | HUANG JiaQi ZHANG Qiang ZHAO MengQiang WEI Fei | 2012 | Chinese Science Bulletin2012，57，2： | 9 |
| 2 | In Silico Screening for Microsatellite Markers from Expressed Sequence Tags of Porphyra yezoensis (Bangiales, Rhodophyta)显示文摘The genomic resources of Porphyra yezoensis expressed sequence tags (ESTs) were utilized to identify simple sequence repeats (SSRs), or microsatellites. This method took the advantage of using ESTs and microsatellites either for the establishment of gene identities or for the acquisition of high polymorphism. The microsatellites can be used as gene markers when microsatellites are tagged to genes. Revealed by bioinformatics analysis, 1 162 out of 21 954 ESTs contained microsatellites and cluster analysis indi- cated that 984 of these ESTs fell into 112 contigs, while the other 178 ESTs were singletons. A total of 290 unique SSR-containing genes were identified. The AAC SSRs were the most populous type of microsatellites. GC-rich microsatellites were predominant among all the microsatellites. | WANG Mengqiang HU Jingjie ZHUANG Yunyun ZHANG Lei LILT Wei MAO Yunxiang | 2007 | Journal of Ocean University of China2007，6，2： | 8 |
| 3 | Gradient Effect on Farmers' Income in the Mountain Areas and its Implication for Poverty Alleviation Strategies:Empirical Analysis from the Upper Reach of Minjiang River,China显示文摘Using four types of settlements in the upper reach of Minjiang River as case,we establish structural models in farmers' income of different settlement patterns based on rural household panel data to reveal the gradient effect on farmers' income and determinants.The results indicate that:(1) except the resettlement area,the incomes for farmers living in river valley,semi-mountain,and high-mountain settlements present a decreasing trend with the elevation increasing;on the contrary,their nonfarm earnings show an increasing trend with the elevation decreasing;(2) from the effect on farmers' income,there is a common feature that the nonfarm earnings and farming incomes have significant positive effects,and family size and productive expenditure have significant negative effects.One exception to this is the productive expenditure,which becomes insignificant in the model of resettlement area;(3) from the way of increasing farmers' income and alleviating poverty,there are great differences for four types of settlements in mountain areas,however,the improvement of agricultural product sales,agricultural production subsidies,the expansion for nonfarm employment,and the control of the family's size are the most effective approaches for poverty alleviation. | FANG Yiping FAN Jie SHEN Maoying SONG Mengqiang | 2012 | Journal of Mountain Science2012，9，6： | 7 |

| 5 | Carbon nanotubes for supercapacitors:Consideration of cost and chemical vapor deposition techniques显示文摘In this topic,we first discussed the requirement and performance of supercapacitors using carbon nanotubes(CNTs) as the electrode,including specific surface area,purity and cost.Then we reviewed the preparation technique of single walled CNTs(SWNTs) in relatively large scale by chemical vapor deposition method.Its catalysis on the decomposition of methane and other carbon source,the reactor type and the process control strategies were discussed.Special focus was concentrated on how to increase the yield,selectivity,and purity of SWNTs and how to inhibit the formation of impurities,including amorphous carbon,multiwalled CNTs and the carbon encapsulated metal particles,since these impurities seriously influenced the performance of SWNTs in supercapacitors.Wish it be helpful to further decrease its product cost and for the commercial use in supercapacitors. | Chao Zheng Weizhong Qian Chaojie Cui Guanghui Xu Mengqiang Zhao Guili Tian Fei Wei | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 3 |
| 6 | Cloning and Analysis of Calmodulin Gene from Porphyra yezoensis Ueda (Bangiales, Rhodophyta)显示文摘In order to understand the mechanisms of signal transduction and anti-desiccation mechanisms of Porphyra yezoensis, cDNA and its genomic sequence of Calmodulin gene (CaM) was cloned by the technique of polymerase chain reaction (PCR) based on the analysis of P. yezoensis ESTs from dbEST database. The result shows that the full-length cDNA of CaM consists of 603 bps including an ORF encoding for 151 amino acids and a terminate codon UGA, while the length of genomic sequence is 1231 bps including 2 exons and 1 intron. The average GC content of the coding region is 58.77%, while the GC content of the third position of this gene is as high as 82.23%. Four Ca2+ binding sites (EF-hand) are found in this gene. The predicted molecular mass of the deduced peptide is 16688.72 Da and the pI is 4.222. By aligning with known CaM genes, the similarity of CaM gene sequence with homologous genes in Chlamydomonas incerta and Chlamydomonas reinhardtii is 72.7% and 72.2% respectively, and the similarity of the deduced amino acid sequence of CaM gene with homologous genes in C. incerta and C. reinhardtii are both 71.5%. This is the first report on CaM from a species of Rhodophyta. | WANG Mengqiang MAO Yunxiang ZHUANG Yunyun KONG Fanna SUI Zhenghong | 2009 | Journal of Ocean University of China2009，8，3： | 3 |
| 7 | Fiber-tip polymer clamped-beam probe for high-sensitivity nanoforce measurements显示文摘Micromanipulation and biological,material science,and medical applications often require to control or measure the forces asserted on small objects.Here,we demonstrate for the first time the microprinting of a novel fiber-tip-polymer clamped-beam probe micro-force sensor for the examination of biological samples.The proposed sensor consists of two bases,a clamped beam,and a force-sensing probe,which were developed using a femtosecond-laser-induced two-photon polymerization(TPP)technique.Based on the finite element method(FEM),the static performance of the structure was simulated to provide the basis for the structural design.A miniature all-fiber micro-force sensor of this type exhibited an ultrahigh force sensitivity of 1.51 nmμN−1,a detection limit of 54.9 nN,and an unambiguous sensor measurement range of~2.9 mN.The Young’s modulus of polydimethylsiloxane,a butterfly feeler,and human hair were successfully measured with the proposed sensor.To the best of our knowledge,this fiber sensor has the smallest force-detection limit in direct contact mode reported to date,comparable to that of an atomic force microscope(AFM).This approach opens new avenues towards the realization of small-footprint AFMs that could be easily adapted for use in outside specialized laboratories.As such,we believe that this device will be beneficial for high-precision biomedical and material science examination,and the proposed fabrication method provides a new route for the next generation of research on complex fiber-integrated polymer devices. | Mengqiang Zou Changrui Liao Shen Liu Cong Xiong Cong Zhao Jinlai Zhao Zongsong Gan Yanping Chen Kaiming Yang Dan Liu Ying Wang Yiping Wang | 2021 | Light(Science & Applications)2021，10，9： | 3 |
| 8 | Process Intensifi cation by CO_(2)for High Quality Carbon Nanotube Forest Growth:Double-Walled Carbon Nanotube Convexity or Single-Walled Carbon Nanotube Bowls?显示文摘Introduction of CO_(2)is a facile way to tune the growth of vertically aligned double-or single-walled carbon nanotube(CNT)forests on wafers.In the absence of CO_(2),a double-walled CNT convexity was obtained.With increasing concentration of CO_(2),the morphologies of the forests transformed first into radial blocks,and finally into bowl-shaped forests.Furthermore,the wall number and diameter distribution of the CNTs were also modulated by varying the amount of CO_(2).With increasing CO_(2)concentration,CNTs with fewer wall number and smaller diameter were obtained.The addition of CO_(2)is speculated to generate water and serve as a weak oxidant for high quality CNT growth.It can tune the growth rate and the morphologies of the forests,prevent the formation of amorphous carbon,and reduce the wall number of the CNTs. | Jiaqi Huang Qiang Zhang Mengqiang Zhao Fei Wei | 2009 | Nano Research2009，2，11： | 2 |
| 9 | Design and realization of 3D printed fiber-tip microcantilever probes applied to hydrogen sensing显示文摘Cantilevers in microelectromechanical systems have the advantages of non-labeling,real-time detection,positioning,and specificity.Rectangular solid,rectangular hollow,and triangular microcantilevers were fabricated on an optical fiber tip via two-photon polymerization.The mechanical properties were characterized using finite element simulations.Coating the microcantilever with a palladium film enabled high sensitivity and rapid hydrogen detection.The shape of the cantilever determines the sensitivity,whereas the thickness of the palladium film determines the response time.Additional microelectromechanical systems can be realized via polymerization combined with optical fibers. | Changrui Liao Cong Xiong Jinlai Zhao Mengqiang Zou Yuanyuan Zhao Bozhe Li Peng Ji Zhihao Cai Zongsong Gan Ying Wang Yiping Wang | 2022 | Light(Advanced Manufacturing)2022，3，1： | 2 |
| 10 | Significant enhancement in the electrical conductance properties of ethylene propylene diene monomer using the nano‐SiO_(2) particles显示文摘To study the effect of nano‐silica particles on the conductivity characteristics of ethylene propylene diene monomer(EPDM)insulation,EPDM nanocomposites with different mass fractions of nano silica were prepared via the melt‐blending method.Scanning electron microscopy was used to analyze the dispersion of nanoparticles in EPDM.Based on the Fourier‐transform infrared spectrum,the bonding properties between the nanoparticles and EPDM were analyzed.The steady‐state current at 30-100°C and 1-20 kV/mm was measured.Moreover,the conductivity characteristic was analyzed.The experimental results show that as the content of nano‐silica increases,the electrical conductivity of EPDM nanocomposite as well as the threshold field strength gradually decreases.Samples with a small number of nanoparticles will increase the activation energy of the carrier conductivity,and the interface region effect introduced by nanoparticles will reduce the carrier mobility and concentration,resulting in a lower conductivity.Comparing the calculated value of the dielectric constant with the measured value can conclude that the high‐field conductance process is a combination of the electrode effect and the body effect,which in this case,Schottky effect dominates. | Chunyu Xu Ruixue Zhao Chuanyang Li Yuanyuan Li Guodong Zhang Tohid Shahsavarian Mengqiang Yuan Zhipeng Lei | 2021 | High Voltage2021，6，3： | 2 |
| 11 | Relationship between Expression of CEA,E-cadherin and Liver Metastasis in Colorectal Cancer显示文摘OBJECTIVE To investigate the expression of E-cadherin andCEA in serum in colorectal carcinoma and their relationship withliver metastasis.METHODS CEA level was measured post-operativelyby radioimmunoassay of 60 patients with colorectal cancer.Immunohistochemical analysis was used to evaluate theexpression of E-cadherin.RESULTS In liver metastasis group,24 patients (24/26,92.3%)were high level of CEA,but only 9 patients in non-liver metastasisgroup.The difference is significant (P=0.004).Expression ofE-cadherin significantly correlated with differentiation,but wasnot associated with Tstage or N stage.Liver metastatic rate innegative expression was higher than that in positive expression.And the survival analysis showed that time of liver metastasis wassignificant different in two groups (P<0.05).CONCLUSION The expression of CEA in serum can be usedto predict liver mestatasis of colorectal cancer after operation.E-cadherin,associated with tumor differentiation,is also a hopefulindicator for the prediction of liver metastasis in patients withcolorectal cancer. | Ning Li Xiaobing Chen Xiangbin Wan Suxia Luo Lili Han Mengqiang Zhou Dengwen Yin Li Zhang | 2008 | Chinese Journal of Clinical Oncology2008，5，6： | 2 |
| 12 | 3D printed fiber-optic nanomechanical bioprobe显示文摘Ultrasensitive nanomechanical instruments,e.g.atomic force microscopy(AFM),can be used to perform delicate biomechanical measurements and reveal the complex mechanical environment of biological processes.However,these instruments are limited because of their size and complex feedback system.In this study,we demonstrate a miniature fiber optical nanomechanical probe(FONP)that can be used to detect the mechanical properties of single cells and in vivo tissue measurements.A FONP that can operate in air and in liquids was developed by programming a microcantilever probe on the end face of a single-mode fiber using femtosecond laser two-photon polymerization nanolithography.To realize stiffness matching of the FONP and sample,a strategy of customizing the microcantilever’s spring constant according to the sample was proposed based on structure-correlated mechanics.As a proof-of concept,three FONPs with spring constants varying from 0.421 N m^(−1)to 52.6 N m^(−1)by more than two orders of magnitude were prepared.The highest microforce sensitivity was 54.5 nmμN^(−1)and the detection limit was 2.1 nN.The Young’s modulus of heterogeneous soft materials,such as polydimethylsiloxane,muscle tissue of living mice,onion cells,and MCF-7 cells,were successfully measured,which validating the broad applicability of this method.Our strategy provides a universal protocol for directly programming fiber-optic AFMs.Moreover,this method has no special requirements for the size and shape of living biological samples,which is infeasible when using commercial AFMs.FONP has made substantial progress in realizing basic biological discoveries,which may create new biomedical applications that cannot be realized by current AFMs. | Mengqiang Zou Changrui Liao Yanping Chen Lei Xu Shuo Tang Gaixia Xu Ke Ma Jiangtao Zhou Zhihao Cai Bozhe Li Cong Zhao Zhourui Xu Yuanyuan Shen Shen Liu Ying Wang Zongsong Gan Hao Wang Xuming Zhang Sandor Kasas Yiping Wang | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 1 |
