| 1 | Artificially triggered lightning and its characteristic discharge parameters in two severe thunderstorms显示文摘The lightning-induced-damages in the mid-latitude regions are usually caused during severe thunder-storms. But the discharge parameters of natural lightning are difficult to be measured. Five lightning flashes have been artificially triggered with the rocket-wire technique during the passage of two severe thunderstorms. The discharge current and close electric field of return stroke in artificially triggered lightning have been obtained in microsecond time resolution by using current measuring systems and electric field change sensors. The results show that the five triggered lightning flashes include 1 to 10 return strokes, and the average return stroke current is 11.9 kA with a maximum of 21.0 kA and a mini-mum of 6.6 kA, similar to the subsequent return strokes in natural lightning. The half peak width of the current waveform is 39 μs, which is much larger than the usual result. The peak current of stroke Ip (kA) and the neutralized charge Q(C) has a relationship of Ip = 18.5Q0.65. The radiation field of return stroke is 5.9 kV·m-1 and 0.39 kV·m-1 at 60 m and 550 m, respectively. The radiation field decreases as r -1.119 with increase of horizontal distance r from the discharge channel. Based on the well-accepted transmission line model, the speed of return stroke is estimated to be about 1.4×108 m·s-1, with a variation range of (1.1―1.6)×108 m·s-1. Because of the similarities of the triggered lightning and natural lightning, the results in this article can be used in the protection design of natural lightning. | QIE XiuShu ZHANG QiLin ZHOU YunJun FENG GuiLi ZHANG TingLong YANG Jing KONG XiangZhen XIAO QingFu WU ShuJun | 2007 | Science China Earth Sciences2007,50,8: | 16 |
| 2 | Heparanase Expression Correlates with Angiogenesis and Lymphangiogenesis in Human Lung Cancer显示文摘Background and objective Heparanase has been thought to be a good molecular marker of tumor,and the heparanase expression level was correlated closely with tumor metastasis. In this study,we investigate the effects of heparanase on angiogenesis and lymphangiogenesis of lung cancer and the relationship between heparanase expression and vascular endothelial growth factor (VEGF),vascular endothelial growth factor-C (VEGF-C). Methods Immunohistochemistry was used to detect the expression of heparanase,VEGF,VEGF-C protein and microvascular density (MVD),lymphatic vessel density (LVD) in 115 cases of non-small cell lung cancer (NSCLC) and 45 cases of adjacent normal tissue samples. Results Our results showed that heparanase expression was significantly increased in 91 (79.13%) of the 115 cases and correlated with lymph node metastasis (node positive rate 87.0%; node negative rate 36.8%; P=0.003). Heparanase positive expression cases have significantly higher concentration of microvascular density (MVD) and lymphatic vessel density (LVD) as compared with heparanase negative expression cases (P<0.01,P<0.01,respectively),heparanase expression was significantly correlated with VEGF,VEGF-C expression in NSCLC. Conclusion Heparanase overexpression was associated with angiogenesis and lymphangiogenesis of lung cancer,targeting of heparanase may represent a significant therapeutic potential for lung cancer. | Qingfu ZHANG Jian MING Yang LI Siyang ZHANG Bo LI Xueshan QIU Enhua WANG | 2009 | 中国肺癌杂志2009,12,8: | 7 |

| 4 | A phase inversion based sponge-like polysulfonamide/SiO_2 composite separator for high performance lithium-ion batteries显示文摘In this work,a sponge-like polysulfonamide(PSA)/SiO_2 composite membrane is unprecedentedly prepared by the phase inversion method,and successfully demonstrated as a novel separator of lithium-ion batteries(LIBs).Compared to the commercial polypropylene(PP) separator,the sponge-like PSA/SiO_2 composite possesses better physical and electrochemical properties,such as higher porosity,ionic conductivity,thermal stability and flame retarding ability.The LiCoO_2/Li half-cells using the sponge-like composite separator demonstrate superior rate capability and cyclability over those using the commercial PP separator.Moreover,the sponge-like composite separator can ensure the normal operation of LiCoO_2/Li half-cell at an extremely high temperature of 90 °C,while the commercial PP separator cannot.All these encouraging results suggest that this phase inversion based sponge-like PSA/SiO_2 composite separator is really a promising separator for high performance LIBs. | Xiao Wang Gaojie Xu Qingfu Wang Chenglong Lu Chengzhong Zong Jianjun Zhang Liping Yue Guanglei Cui | 2018 | Chinese Journal of Chemical Engineering2018,26,6: | 6 |

| 6 | Mission-Oriented Configuration Model of Aircraft Carrying Spares and Dynamic Optimization Policy显示文摘Spare parts are critical to scheduled maintenance and fault repair,and can directly affect the readiness and combat capability of equipment.Equipment′s capacity of carrying spares is influenced by its storage space and scales,so it is necessary to consider economic factors,e.g.spares cost,as well as non-economic ones,such as spares volume,mass and scale,when optimizing spares configuration.Aiming at this problem,the optimization model based on multi-constraints for carrying spares is built by METRIC theory and system analysis.Through the introduction of Lagrange factors,the spares cost is transformed to shadow price,and the optimization method for carrying spares and the dynamic adjustment policy of Lagrange factors are proposed.The result of a given example is analyzed,and demonstrates that the proposed model can be optimized with all constraints,and the research can provide a new way for carrying spares optimization. | Ruan Minzhi Wang Rui Kong Qingfu | 2016 | Transactions of Nanjing University of Aeronautics and Astronautics2016,33,5: | 3 |
| 7 | Modified accumulation of selected heavy metals in Bt transgenic rice显示文摘Safety assessment of genetically modified crops generally does not take into account the potential hazard of altered patterns of heavy metal accumulation in plants. A pot experiment was conducted under greenhouse conditions to evaluate the impact of heavy metal amendments on the accumulation of Cd, Cu, Pb and Zn in a Bt transgenic rice Ke-Ming-Dao (KMD) and its wild-type Xiushui 11 (Xs11). In control soils, significant difference was only found in contents of Cu (p < 0.01) and Pb (p < 0.05) in straw between KMD and Xs11. At three levels of Cd amendments (5, 10, and 20 mg/kg), the Cd contents in grain and straw of KMD were significantly higher than those of Xs11, and all grain Cd contents were significantly higher than the International Criteria (0.2-0.4 mg/kg) as specified by the Codex Alimentarius Commission (CAC). These results implied that it may be unsafe for growing Bt transgenic rice in heavily Cd-polluted areas. No significant difference in Zn was found between the two varieties with the exception of roots at Zn amendment level of 600 mg/kg, while Pb contents in KMD were much higher in the straw at the lead amendment level of 1000 mg/kg and in the root at 250 mg Pb/kg. Data on the heavy metal accumulation patterns for the genetically modified rice may be used for the selection of growing areas as well as for plant residue management for Bt rice. | WANG Haiyan, HUANG Jianzhong, YE Qingfu, WU Dianxing, CHEN Ziyuan Institute of Nuclear Agricultural Sciences, Key Laboratory of Nuclear Agricultural Sciences of Ministry of Agriculture and Zhejiang Province, Zhejiang University, Hangzhou 310029, China | 2009 | Journal of Environmental Sciences2009,21,11: | 3 |
| 8 | Therapeutic effects of low-frequency phonophoresis with a Chinese herbal medicine versus sodium diclofenac for treatment of knee osteoarthritis: a double-blind, randomized, placebo-controlled clinical trial显示文摘OBJECTIVE: To evaluate the therapeutic effects of low-frequency phonophoresis with a Chinese herbal medicine(CHM) compared with sodium diclofenac(SD) for knee osteoarthritis(KOA).METHODS: In this double-blind, randomized, placebo-controlled trial, 100 KOA patients were assigned randomly to a placebo group, a CHM group,or SD group. Low-frequency phonophoresis was used to improve the efficiency of drug delivery.Pain at rest [using a visual analog scale(VAS)], pain on movement(VAS), and range of motion(degrees) in the three groups were evaluated using the Western Ontario and Mc Master Universities Osteoarthritis Index(WOMACAI) scores. Safety assessments comprised emergency adverse events, aswell as laboratory tests of blood biochemistry, creatinine, blood urea nitrogen, alanine aminotransferase and aspartate aminotransferase.RESULTS: Significant improvements were found after treatment in all outcome measures except stiffness and range of motion in patients in the CHMP group and SDP group(P < 0.05). No significant differences in all outcome measures were found between the CHMP group and SDP group.CONCLUSION: CHMP and SDP can show good therapeutic effects for KOA in terms of relieving pain and improving physical function. | Zhao Jun Wang Qingfu Wu Ji Shi Xinchao Qi Qingxue Zheng Haoyun Lang Song Yang Lili Zhang Dong | 2016 | Journal of Traditional Chinese Medicine2016,36,5: | 3 |
| 9 | Lithium bis(oxalate)borate crosslinked polymer electrolytes for high-performance lithium batteries显示文摘Solid electrolytes play a vital role in solid-state Li secondary batteries,which are promising high-energy storage devices for new-generation electric vehicles.Nevertheless,obtaining a suitable solid electrolyte by a simple and residue-free preparation process,resulting in a stable interface between electrolyte and electrode,is still a great challenge for practical applications.Herein,we report a self-crosslinked polymer electrolyte(SCPE)for high-performance lithium batteries,prepared by a one-step method based on 3-methoxysilyl-terminated polypropylene glycol(SPPG,a liquid oligomer).It is worth noting that lithium bis(oxalate)borate(Li BOB)can react with SPPG to form a crosslinked structure via a curing reaction.This self-formed polymer electrolyte exhibits excellent properties,including high roomtemperature ionic conductivity(2.6×10^(-4) S cm^(-1)),wide electrochemical window(4.7 V),and high Li ion transference number(0.65).The excellent cycling stability(500 cycles,83%)further highlights the improved interfacial stability after the in situ formation of SCPE on the electrode surface.Moreover,this self-formation strategy enhances the safety of the battery under mechanical deformation.Therefore,the present self-crosslinked polymer electrolyte shows great potential for applications in high-performance lithium batteries. | Xiao Wang Jujie Sun Changhao Feng Xiujuan Wang Minghan Xu Jingjiang Sun Ning Zhang Jun Ma Qingfu Wang Chengzhong Zong Guanglei Cui | 2021 | Journal of Energy Chemistry2021,30,4: | 2 |

| 12 | Ultralight aerogel sphere composed of nanocellulose-derived carbon nanofiber and graphene for excellent electromagnetic wave absorption显示文摘A novel type of three-dimensional ultralight aerogel sphere,consisting of one-dimensional nanocellulose-derived carbon fibers and two-dimensional graphene layers,was prepared based on a developed drop-freeze-drying followed by carbonization approach.The nanofibrous carbon efficiently prevents the agglomeration of the graphene layers,which,in turn,reduces the shrinkage and maintains the structural stability of the hybrid carbon aerogel spheres.Consequently,the aerogel spheres showing an ultralow-density of 2.8 mg/cm^(3) and a porosity of 99.98%accomplish the tunable dielectric property and electromagnetic wave(EMW)absorption performance.The high-efficiency utilization of biomass-derived fibrous nanocarbon,graphene,the porous structure of the hybrid aerogel spheres leads to the excellent EMW absorption performance.The aerogel spheres display an effective absorption bandwidth of 6.16 GHz and a minimum reflection loss of−70.44 dB even at a filler loading of merely 3 wt.%,significantly outperforming that of other biomass-derived carbon-based EMW absorbing materials.This work offers a feasible,facile,scalable approach for fabricating high-performance and sustainable biomass-based aerogels,suggesting a tremendous application potential in EMW absorption and aerospace. | Runa Zhang Bin Li Yunfei Yang Na Wu Zhuyin Sui Qingfu Ban Lili Wu Wei Liu Jiurong Liu Zhihui Zeng | 2023 | Nano Research2023,16,5: | 2 |
