1A Review on Graphene-Based Gas/Vapor Sensors with Unique Properties and Potential Applications显示文摘Graphene-based gas/vapor sensors have attracted much attention in recent years due to their variety of structures, unique sensing performances, room-temperature working conditions, and tremendous application prospects, etc.Herein, we summarize recent advantages in graphene preparation, sensor construction, and sensing properties of various graphene-based gas/vapor sensors, such as NH_3, NO_2, H_2, CO, SO_2, H_2S, as well as vapor of volatile organic compounds.The detection mechanisms pertaining to various gases are also discussed. In conclusion part, some existing problems which may hinder the sensor applications are presented. Several possible methods to solve these problems are proposed, for example, conceived solutions, hybrid nanostructures, multiple sensor arrays, and new recognition algorithm.Tao Wang Da Huang Zhi Yang Shusheng Xu Guili He Xiaolin Li Nantao Hu Guilin Yin Dannong He Liying Zhang 2016Nano-Micro Letters2016,8,2:18
2Artificially 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 2007Science China Earth Sciences2007,50,8:16
3Magnolol additive as a replacer of antibiotic enhances the growth performance of Linwu ducks显示文摘Magnolol rich in Magnolia officinalis is a bioactive polyphenolic compound. The aim of this study was to examine the effects of magnolol additive(MA) on growth performance, expression levels of antioxidantrelated genes, and intestinal mucosal morphology of Linwu ducks aged from 49 to 70 days, comparing with that of an antibiotic additive(colistin sulfate [CS]). A total of 275,49-day-old ducks were assigned to5 groups with 5 cages of 11 ducks each and fed diets supplemented with 0,100, 200 and 300 mg of MA/kg and 300 mg of CS/kg for 3 weeks, respectively. The results showed that the average daily body weight gain(ADG) was increased significantly in MA-fed groups(200 and 300 mg/kg), compared with the basal diet(BD) group(P < 0.05). The mRNA levels of superoxide dismutase-1(SOD1), manganese superoxide dismutase-2(MnSOD2) and catalase(CAT) were also increased significantly in MA groups(P < 0.05). In addition, hematoxylin and eosin staining revealed that Linwu ducks fed the diets with MA had more intact intestinal mucosa than those fed the BD and CS diets. In addition, ileal villus height, ileal villus height/crypt depth ratio(V/C) and duodenal V/C were also improved significantly(P < 0.05). Taken together, these data demonstrated that MA is an effective feed additive to enhance the growth performance of the Linwu ducks by improving the antioxidant and intestinal mucosal status, suggesting that MA will be a potential additive to replace antibiotic(CS).Qian Lin Jianfei Zhao Kun Xie Yushi Wang Guili Hu Guitao Jiang Qiuzhong Dai Zhiyong Fan Jianhua He Xi He De-Xing Hou 2017Animal Nutrition2017,,2:14

5Use of land's cooperative object to estimate UAV's pose for autonomous landing显示文摘The research of unmanned aerial vehicles’(UAVs’)autonomy navigation and landing guidance with computer vision has important signifcance.However,because of the image blurring,the position of the cooperative points cannot be obtained accurately,and the pose estimation algorithms based on the feature points have low precision.In this research,the pose estimation algorithm of UAV is proposed based on feature lines of the cooperative object for autonomous landing.This method uses the actual shape of the cooperative-target on ground and the principle of vanishing line.Roll angle is calculated from the vanishing line.Yaw angle is calculated from the location of the target in the image.Finally,the remaining extrinsic parameters are calculated by the coordinates transformation.Experimental results show that the pose estimation algorithm based on line feature has a higher precision and is more reliable than the pose estimation algorithm based on points feature.Moreover,the error of the algorithm we proposed is small enough when the UAV is near to the landing strip,and it can meet the basic requirements of UAV’s autonomous landing.Xu Guili Qi Xiaopeng Zeng Qinghua Tian Yupeng Guo Ruipeng Wang Biao 2013Chinese Journal of Aeronautics2013,26,6:8
6Study on Modification Mechanism of Rare Earth in ZA27 Cast Alloy with Electronic Theory and Molecular Dynamics Method显示文摘A model of liquid ZA27 cast alloy is established according to molecular dynamics theory and an atomic structural model of co-existent α phase and liquid is also presented by means of computer programming. Recursion method is adopted to calculate the electronic structure of RE (rare earth) in grains and around phase boundaries respectively. The calculation shows that RE is more stable around phase boundaries than in grains, which explains the fact that the solution of RE in α phase is less, and RE mainly aggregates in front of phase boundary. The calculations of bonding order integrals also show that RE in front of phases hardly solidify onto the grain surfaces as active element so as to prevent grains growth and refine the grains. As a result, the modification mechanism of RE may be explained from the view of electronic structure.Guili LIU, Rongde LI and Zhenping ZHOUSchool of Materials Science and Engineering, Shenyang University of Technology, Shenyang 110023, China 2004Journal of Materials Science & Technology2004,20,5:6
7Impacts of Climatic Change on River Runoff in Northern Xinjiang of China over Last Fifty Years显示文摘The characteristics of climatic change and river runoff, as well as the response of river runoff to climatic change in the northern Xinjiang are analyzed on the basis of the hydrological and meteorological data over the last 50 years by the methods of Mann-Kendall nonparametric test and the nonlinear regression model. The results show that: 1) The temperature and the precipitation increased significantly in the whole northern Xinjiang, but the precipitation displayed no obvious change, or even a decreasing trend in the northern mountainous area of the northern Xinjiang. 2) River runoff varied in different regions in the northern Xinjiang. It significantly increased in the northern slope of the Tianshan Mountains and the north of the northern Xinjiang (p = 0.05), while slightly increased in the west of the northern Xinjiang. 3) North Atlantic Oscillation (NAO) affects river runoff by influencing temperature and precipitation. The NAO and precipitation had apparent significant correlations with the river runoff, but the temperature did not in the northern Xinjiang. Since the mid-1990s river runoff increase was mainly caused by the increasing temperature in the northern slope of the Tianshan Mountains and the north of the northern Xinjiang. Increased precipitation resulted in increased river runoff in the west of the northern Xinjiang.YANG Yuhui CHEN Yaning LI Weihong WANG Minzhong SUN Guili 2010Chinese Geographical Science2010,20,3:6

13Adenovirus-mediated LIGHT gene modification in murine B-cell lymphoma elicits a potent antitumor effect显示文摘Here,we investigated the antitumor effect of adenovirus-mediated gene transfer of LIGHT,the tumor-necrosis factor(TNF)superfamily member also known as TNFSF14,in the murine A20 B-cell lymphoma.LIGHT gene modification resulted in upregulated expression of Fas and the accessory molecule-intercellular adhesion molecule-1(ICAM-1)on A20 cells and led to enhanced A20 cell apoptosis.LIGHT-modified A20 cells effectively stimulated the proliferation of T lymphocytes and interferon(IFN)-c production in vitro.Immunization of BALB/c mice with a LIGHT-modified A20 cell vaccine efficiently elicited protective immunity against challenge with the parental tumor cell line.Adenovirus-mediated gene transfer of LIGHT by intratumoral injection exerted a very potent antitumor effect against pre-existing A20 cell lymphoma in BALB/c mice.This adenovirus-mediated LIGHT therapy induced substantial splenic natural killer(NK)and cytotoxic T lymphocyte(CTL)activity,enhanced tumor infiltration by inflammatory cells and increased chemokine expression of CC chemokine ligand 21(CCL21),IFN-inducible protein-10(IP-10)and monokine induced by IFN-c(Mig)from tumor tissues.Thus,adenovirus-mediated LIGHT therapy might have potential utility for the prevention and treatment of B-cell lymphoma.Guili Hu Yang Liu Hong Li Dekuang Zhao Liuqing Yang Jiangen Shen Xuejun Hong Xuetao Cao Qingqing Wang 2010Cellular & Molecular Immunology2010,7,4:3

15A gigantic jet event observed over a thunderstorm in China's Mainland显示文摘Gigantic jet(GJ) is a type of large-scaled transient discharge which occurs above thunderstorms.It connects the thunderstorms and ionosphere directly.Compared with the other transient luminous events(TLEs),gigantic jet is very difficult to be seen from the ground.We report a GJ event that was clearly recorded in eastern China(storm center located at 35.6°N,119.8°E,near the Huanghai Sea) at 20:16:22(local time) on 12 August,2010.It is by far the furthest from the equator ground-based GJ recorded over summer thunderstorm.The top altitude of this GJ was estimated to be about 89 km.The GJ-producing storm was a multi-cell thunderstorm and the GJ event occurred in the storm developing stage,with the lowest cloud-top brightness temperature about 73°C and the maximum radar echo top around 17 km.Altitudes with reflectivity of 45 dBZ were estimated to reach 12-14 km.Different from results from other countries that positive CGs(Cloud-to-ground lightnings) dominated during a time period centered at GJ,our study shows that negative CGs dominated during a time period centered at the GJ event and during most of the storm lifetime in this study,indicating a diversity of the lightning activity in the GJ-producing storms.It is interesting that two different storms produced two types of TLEs,that is,the GJ-producing storm only produced one GJ event during its lifetime and five sprites were produced over another storm,different from the other study that sprites and GJs were usually produced by the same storm,enriched the knowledge of GJ-producing storms.In addition,the GJ event in this study is located beyond the effective coverage area(30°S-30°N) of the ISUAL instruments onboard the FORMOSAT II satellite,and results of this study could be useful for GJ studies in the future.YANG Jing FENG GuiLi 2012Chinese Science Bulletin2012,57,36:3

17Formation Mechanism of Curved Martensite Structures in Cu-based Shape Memory Alloys显示文摘The curved martensite structures have been observed in CuZnAl-based shape memory alloys by both transmission electron microscope and optical microscope. It was found that the curved martensite structures observed in as-solution treated, as-aged and as-trained alloys usually occurred around dislocation tangles or precipitate, at the plate boundary or grain boundary, and when the growing plates collided with each other or alternate mutually.Yujun BAI, Qiquan SHI,Guili GENG, Dongsheng SUN and Xiufang BIAN (Institute of Materials Engineering, Shandong University of Technology, Jinan 250061, China) 2000Journal of Materials Science & Technology2000,16,1:2
18A man-made object detection algorithm based on contour complexity evaluation显示文摘Man-made object detection is of great significance in both military and civil areas, such as search-and-rescue missions at sea, traffic signs recognition during visual navigation, and targets location in a military strike. Contours of man-made objects usually consist of straight lines, corner points, and simple curves. Motivated by this observation, a man-made object detection method is proposed based on complexity evaluation of object contours. After salient contours which keep the crucial information of objects are accurately extracted using an improved mean-shift clustering algorithm, a novel approach is presented to evaluate the complexity of contours. By comparing the entropy values of contours before/after sampling and linear interpolation, it is easy to distinguish between man-made objects and natural ones according to the complexity of their contours.Experimental results show that the presented method can effectively detect man-made objects when compared to the existing ones.Guili XU Zhengbing WANG Yuehua CHENG Yupeng TIAN Chao ZHANG 2017Chinese Journal of Aeronautics2017,30,6:2
19The Class Ⅲ peroxidase gene OsPrx30,transcriptionally modulated by the AT-hook protein OsATH1, mediates rice bacterial blight-induced ROS accumulation显示文摘Class Ⅲ peroxidases(CⅢ Prxs) play critical roles in plant immunity by scavenging reactive oxygen species(ROS). However, the functions of CⅢ Prxs in rice(Oryza sativa L.) immunity are largely unexplored. Here, we report a Prx precursor, OsPrx30,that is responsive to the bacterial blight Xanthomonas oryzae pv. oryzae(Xoo). OsPrx30 was primarily expressed in rice roots, leaves, and stems,and its protein product was mainly localized at the endoplasmic reticulum. Overexpression of OsPrx30 enhanced the plant’s susceptibility to Xoo by maintaining a high level of peroxidase(POD) activity and reducing the content of H2O2, whereas depletion of OsPrx30 had the opposite effects. Furthermore, we identified an AT-hook transcription factor, Os ATH1, that is specifically bound to the OsPrx30 promoter. As observed in plants overexpressing OsPrx30, depletion of Os ATH1 enhanced susceptibility to Xoo. Finally, we demonstrated that depletion of Os ATH1 increased histone H3 acetylation at the AT-rich region of the OsPrx30 promoter.Taken together, these results reveal a mechanism underlying the POD-induced natural resistance to bacterial diseases and suggest a model for transcription regulation of Prx genes in rice.Hao Liu Shuangyu Dong Ming Li Fengwei Gu Guili Yang Tao Guo Zhiqiang Chen Jiafeng Wang 2021Journal of Integrative Plant Biology2021,63,2:2
