| 1 | Climatic and lake environmental changes in the Serling Co region of Tibet over a variety of timescales显示文摘The Serling Co region is located at the transitional zone of the interaction between the Indian monsoon and the westerlies over the Tibetan Plateau. The Serling Co lake covers a water area of2,389 km2(June 2017) in a 45,530 km2drainage basin. Under the dramatic hydro-meteorological changes on the Tibetan Plateau in recent decades, and complex hydrological compositions of rivers and lakes in the basin, the lake area expanded by 43%, from1,667 km2in 1976, to 2,389 km2in 2017 (1)In 2014 it surpassed Nam Co as the largest lake on the Tibetan Plateau [2], and exerts significant effect on regional environmental conditions. | Liping Zhu Junbo Wang Jianting Ju Ning Ma Yinsheng Zhang Chong Liu Boping Han Linshan Liu Mingda Wang Qingfeng Ma | 2019 | Science Bulletin2019，64，7： | 13 |
| 2 | Monte-Carlo simulation of pinhole collimator of a small field of view gamma camera for small animal imaging显示文摘Needs in scintimammography applications,especially for small animal cardiac imaging,lead to develop a small field of view,high spatial resolution gamma camera with a pinhole collimator.However the ideal pinhole collimator must keep a compromise between spatial resolution and sensitivity.In order to design a pinhole collimator with an optimized sensitivity and spatial resolution,the spatial resolution and the geometric sensitivity response as a function of the source to collimator distance has been obtained by means of Monte-Carlo simulation for a small field of view gamma camera with a pinhole collimator of various-hole diameters.The results show that the camera with pinhole of 1 mm,1.5 mm and 2 mm diameter has respectively spatial resolution of 1.5 mm,2.25 mm and 3 mm and geometric sensitivity of 0.016%,0.022%and 0.036%,while the source to collimator distance is 3 cm.We chose the pinhole collimator with hole diameter size of 1.2 mm for our the gamma camera designed based on the trade-off between sensitivity and resolution. | ZHU Jie MA Wenyan ZHU Yufeng MA Hongguang WU Yuelei HU Huasi ZHANG Boping HUO Yonggang LIU Silu JIAN Bin WANG Zhaomin | 2009 | Nuclear Science and Techniques2009，20，1： | 4 |
| 3 | Multi-phase structure and electrical properties of Bi_(0.5)Li_(0.5)ZrO_3 doping K_(0.48)Na_(0.56)NbO_3 lead-free piezoelectric ceramics显示文摘(1–x)K_(0.48)Na_(0.56)NbO_3–xBi_(0.5)Li_(0.5)ZrO_3(KNN–x BLZ, x = 0–0.06) lead-free piezoelectric ceramics were prepared by the conventional solid-state sintering method, and their phase structures and electric properties as well as T_C were systematically investigated. The orthorhombic–tetragonal(O–T) two phases were detected in all(1–x)K_(0.48)Na_(0.56)NbO_3–xBi_(0.5)Li_(0.5)ZrO_3 ceramics at 0.01 ≤ x ≤ 0.05. Due to the appropriate ratio between O phase and T phase(CO/C T= 45/55), high piezoelectric properties of d 33= 239 pC/N, k_p= 34%, and P_r = 25.23 μC/cm^2 were obtained at x = 0.04. Moreover, a high T_C = 348 ℃ was also achieved in KNN–x BLZ ceramic at x = 0.04. These results indicate that (1–x)K_(0.48)Na_(0.56)NbO_3–xBi_(0.5)Li_(0.5)ZrO_3 system is a promising candidate for high-temperature piezoelectric devices. | Xiaoyan PENG Boping ZHANG Lifeng ZHU Lei ZHAO Ruixiao MA Bo LIU Xiaodong WANG | 2018 | Journal of Advanced Ceramics2018，7，1： | 4 |
| 4 | Effect of Li content on the microstructure and properties of lead-free piezoelectric(K_(0.5)Na_(0.5))_(1-x)Li_xNbO_3 ceramics prepared by SPS显示文摘Lead-free piezoelectric(K_(0.5)Na_(0.5))_(1-x)Li_xNbO_3(x=0at%-20at%)ceramics were synthesized by spark plasma sintering(SPS) at low temperature and the effects of LiNbO_3 addition on its crystal structure and properties were also studied.When the Li content was less than 6at%,a single proveskite phase with the similar structure of(K_(0.5)Na_(0.5))NbO_3 was formed;and a secondary phase with K_3Li_2Nb_5O_(15) structure was observed in the 6at%≤x≤20at% compositional range.Furthermore,LiNbO_3 existed as the third phase when the Li content was higher than 8at%.The grain sizes increased from 200-500 nm to 5-8μm when the K_3Li_2Nb_5O_(15) and LiNbO_3 like phases were formed.With increasing Li content,the relative density of the ceramics first decreased from 97% to 93% and then kept constant.The piezoelectric coefficient d_(33),dielectric constant,and planner electromechanical coupling factor exhibited a de- creasing tendency with increasing Li content because of the decrease in density and the formation of the secondary phase such as K_3Li_2Nb_5O_(15) and LiNbO_3.The formation of dense microstructure with a single phase is necessary in improving the properties of the (K_(0.5)Na_(0.5))_(1-x)Li_xNbO_3 ceramics. | Pei Zhao Boping Zhang Ke Wang Limin Zhang Hailong Zhang | 2008 | Journal of University of Science and Technology Beijing2008，15，3： | 3 |
| 5 | A three-dimensional coupled physical-biological model study in the spring of 1993 in the Bohai Sea of China显示文摘A three-dimensional (3-D) coupled physical and biological model was used to investigate the physical processes and their influence on the ecosystem dynamics of the Bohai Sea of China. The physical processes include M2 tide, time-varying wind forcing and river discharge. Wind records from 1 to 31 May in 1993 were selected to force the model. The biological model is based on a simple, nitrate and phosphate limited, lower trophic food web system. The simulated results showed that variation of residual currents forced by M2 tide, river discharge and time-varying wind had great impact on the distribution of phytoplankton biomass in the Laizhou Bay. High phytoplankton biomass appeared in the upwelling region. Numerical experiments based on the barotropic model and baroclinic model with no wind and water discharge were also conducted. Differences in the results by the baroclinic model and the barotropic model were significant: more patches appeared in the baroclinic model comparing with the barotropic model. And in the baroclinic model, the subsurface maximum phytoplankton biomass patches formed in the stratified water. | WANG Hui LIU Guimei SUN Song HAN Boping FU Xiang | 2007 | Acta Oceanologica Sinica2007，26，6： | 3 |
| 6 | Induction of chemotaxis to sodium chloride and diacetyl and thermotaxis defects by microcystin-LR exposure in nematode Caenorhabditis elegans显示文摘Apart from the liver disruption, embryotoxicity and genotoxicity, microcystin (MC)-LR also could cause neurotoxicity. Nematode Caenorhabditis elegans was explored as a model to study the neurotoxicity. In the present study, we provided evidence to indicate the neurotoxicity on chemotaxis to NaCl and diacetyl, and thermotaxis from MC-LR exposure to C. elegans. As a result, higher concentrations of MC-LR caused significantly severe defects of chemotaxis to NaCl and diacetyl, and thermotaxis. The neurotoxicity on chemotaxis to NaCl and diacetyl, and thermotaxis from MC-LR exposure might be largely mediated by the damage on the corresponding sensory neurons (ASE, AWA, and AFD) and interneuron AIY. The expression levels of che-1 and odr-7 were significantly decreased (P < 0.01) in animals exposed to MC-LR at concentrations lower than 10 μg/L, whereas the expression levels of ttx-1 and ttx-3 could be significantly (P < 0.01) lowered in animals even exposed to 1 μg/L of MC-LR. Moreover, both the chemotaxis to NaCl and diacetyl and the thermotaxis were more significantly reduced in MC-LR exposed mutants of che-1(p674), odr-7(ky4), ttx-1(p767), and ttx-3(ks5) than those in exposed wild-type N2 animals at the same concentrations. | LI Yunhui YE Huayue DU Min ZHANG Yanfen YE Boping PU Yuepu WANG Dayong | 2009 | Journal of Environmental Sciences2009，21，7： | 2 |

| 9 | Effects of Mg on Mechanical Properties of 35CrNi3MoV Steel显示文摘The effects of Mg on the mechanical properties of 35CrNi3MoV steel has been studied in this paper. The results show that Mg has less effect on the tensile properties and hardness of the steel at room temperature, but a right amount of Mg improves impact and fracture toughness and decreases the fracture-transition temperature considerably due to inclusions modification, as well as prolongs the notch stress rupture life dramatically through strengthening grain boundary and modifying boundary carbides. There is an optimum Mg content, which is about 0.0030% in the experimental 35CrNi3MoV | Yu, Yueguang Fu, Jie Wang, Anren Chen, Boping Sun, Wenshan | 1998 | Journal of Materials Science & Technology1998，14，2： | 1 |

| 11 | Removal of gaseous volatile organic compounds via vacuum ultraviolet photodegradation: Review and prospect显示文摘Volatile organic compounds(VOCs) have attracted much attention for decades as they are the precursors of photochemical smog and are harmful to the environment and human health. Vacuum ultraviolet(VUV) photodegradation is a simple and effective method to decompose VOCs (ranging from tens to hundreds of ppmV) without additional oxidants or catalysts in the air at atmospheric pressure. In this paper, we review the research progress of VOCs removal via VUV photodegradation. The fundamentals are outlined and the key operation factors for VOCs degradation, such as humidity, oxygen content, VOCs initial concentration, light intensity, and flow rate, are discussed. VUV photodegradation of VOCs mixture is elucidated. The application of VUV photodegradation in combination with ozoneassisted catalytic oxidation(OZCO) and photocatalytic oxidation(PCO) systems, and as the pre-treatment technique for biological purification are illustrated. Based on the summary,we propose the challenges of VUV photodegradation and perspectives for its future development. | Xue Sun Chaolin Li Boping Yu Jingwen Wang Wenhui Wang | 2023 | Journal of Environmental Sciences2023，，3： | 1 |

| 16 | Identification of UGT85A glycosyltransferases associated with volatile conjugation in grapevine(Vitis vinifera × Vitis labrusca)显示文摘Glycosylated volatiles are considered as hidden aroma precursors that affect fruit flavor and are involved in plant defense response. Several uridine-diphosphate(UDP)-glycosyltransferase(UGT) members related to the glycosylation of volatiles have been identified from grapevine berries. Although grapevine leaves produced much higher levels of glycosylated volatiles than berries, UGTs responsible for the production of glycosylated volatiles in leaves have not yet been identified. Here, eight novel UGT genes were cloned, among these four members that belong to UGT85A family(named UGT85A24, UGT85A25, UGT85A26, and UGT85A27) were localized in the cytoplasm and their recombinant proteins showed activity toward volatiles detected in grapevine, with geraniol as the preferred substrate in vitro. Two UGT genes with 98.1% homology differ in R/S-linalool selection. The UGT85A26-catalyzed substrate showed enrichment in S-linalool, whereas UGT85A27 showed a strong preference for R-linalool. UGT85A24 and UGT85A25 were expressed mainly in berries, and UGT85A26 and UGT85A27 were expressed predominantly in grapevine mature leaves and correlated with the highest content of glycosylated volatiles in the mature leaves. Methyl jasmonate(MeJA) induced the expression of UGT85A26 and UGT85A27 as well as the production of linalyl-β-glucoside, citronellyl-β-glucoside and phenethyl-β-glucoside. Transient overexpression of UGT85A26 and UGT85A27 in tobacco leaves led to the accumulation of linalyl-β-glucoside and an increase in citronellyl-β-glucoside in vivo. These results indicate that the expression of UGT85A26 and UGT85A27 is a major regulator affecting the content of glycosylated volatiles in grapevine. | Xiangmei Cao Dan Jiang Hanqing Wang Boping Wu Jianhui Cheng Bo Zhang | 2023 | Horticultural Plant Journal2023，9，6： | 0 |
| 17 | Repetitive DNA Sequences from the X Chromosome of the Spiny Eel (Mastacembelus aculeatus)显示文摘To investigate the characters of repetitive DNA se-quence in the sex chromosomes of the spiny eel (Mastacembelus aculeatus), the X chromosomal library was screened and a family of repetitive sequence, consisting of Ma 1-Ma 6, was isolated. The fluorescence in situ hybridization (FISH) result confirmed that Ma 1- Ma 5 dispersed over sex chromosomes and all autosomes, whereas, Ma 6 is sex chromosome-specific and distributed only on the C-band positive regions of X chromosome, and Ma 6 maybe the main components of the heterochromatic regions of X chro-mosome. This study provides additional information about the evolution of sex chromosomes in lower vertebrates such as fish. | ZHAO Gang YU Qixing CHEN Ji WANG Boping ZANG Yating LIU Jiangdong | 2009 | Wuhan University Journal of Natural Sciences2009，14，2： | 0 |
| 18 | Enhanced piezoelectric properties and thermal stability of Bi_(0.5)Na_(0.5)TiO_(3)modified BiFeO_(3)-BaTiO_(3)ceramics with morphotropic phase boundary显示文摘Morphotropic phase boundary(MPB)plays a key role in tuning piezoelectric responses of ferroelectric ceramics.Here,Bi_(0.5)Na_(0.5)TiO_(3)modified BiFeO_(3)-BaTiO_(3)ternary solid solutions of 0.7BiFeO_(3)-(0.3-x)BaTiO_(3)-xBi_(0.5)Na_(0.5)TiO_(3)(referred to as BF-BT-xBNT,0.00≤x≤0.04)were prepared for lead-free piezo-electrics.All the ceramics exhibit an MPB with coexisting rhombohedral(R)and tetragonal(T)phases,and the R/T phase ratio decreases upon increasing x.The increment of BNT promotes the grain growth,lowers the leakage current and Curie temperature(TC),and gradually drives the ferroelectric to relaxor transition.Because of the MPB with appropriate R/T phase ratio,increased grain size and density,and decreased leakage current,the well-balanced performance between d_(33)=206 pC/N and TC=488℃is obtained in x=0.01 case.In addition,the further enhanced in-situ d_(33)=286e347 pC/N is obtained in BF-BT-xBNT ceramics along with the improved depolarization temperature T_(d)from 280 to 312℃,showing a potential application for lead-free piezoceramics at high temperature. | Shuai Cheng Boping Zhang Shengjie Ai Hongbao Yu Xin Wang Jiahao Yang Changrong Zhou Jingtai Zhao Guanghui Rao | 2023 | Journal of Materiomics2023，9，3： | 0 |
