| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Exotic origin of the Chinese continental shelf: new insights into the tectonic evolution of the western Pacific and eastern China since the Mesozoic显示文摘The effect of paleo-Pacific subduction on the geological evolution of the western Pacific and continental China is likely complex. Nevertheless, our analysis of the distribution of Mesozoic granitoids in the eastern continental China in space and time has led us to an interesting conclusion: The basement of the continental shelf beneath East and South China Seas may actually be of exotic origin geologically unrelated to the continental lithosphere of eastern China. By accepting the notion that the Jurassic–Cretaceous granitoids in the region are genetically associated with western Pacific subduction and the concept that subduction may cease to continue only if the trench is being jammed, then the termination of the granitoidmagmatism throughout the vast region at *88 ± 2 Ma manifests the likelihood of ‘‘sudden'', or shortly beforehand(*100 Ma), trench jam of the Mesozoic western Pacific subduction. Trench jam happens if the incoming‘‘plate'' or portion of the plate contains a sizeable mass that is too buoyant to subduct. The best candidate for such a buoyant and unsubductable mass is either an oceanic plateau or a micro-continent. We hypothesize that the basement of the Chinese continental shelf represents such an exotic, buoyant and unsubductable mass, rather than seaward extension of the continental lithosphere of eastern China. The locus of the jammed trench(i.e., the suture) is predictably located on the shelf in the vicinity of, and parallel to, the arc-curved coastal line of the southeast continental China. It is not straightforward to locate the locus in the northern section of the East China Sea shelf because of the more recent(\20 Ma) tectonic re-organization associated with the opening of the Sea of Japan. We predict that the trench jam at *100 Ma led to the re-orientation of the Pacific plate motion in the course of NNW direction as inferred from the age-progressive Emperor Seamount Chain of Hawaiian hotspot origin(its oldest unsubdued Meiji and Detroit seamounts are *82 Ma),making the boundary between the Pacific plate and the newly accreted plate of eastern Asia a transform fault at the location east of the continental shelf of exotic origin. This explains the apparent *40 Myr magmatic gap from *88to *50 Ma prior to present-day western Pacific subduction initiation. We propose that basement penetration drilling on well-chosen sites is needed to test the hypothesis in order to reveal the true nature of the Chinese continental shelf basement. This testing becomes critical and cannot longer be neglected in order to genuinely understand the tectonic evolution of the western Pacific and its effect on the geology of eastern China since the Mesozoic, includingthe cratonic lithosphere thinning, related magmatism/mineralization, and the mechanism of the subsequent South China Sea opening, while also offering novel perspectives on aspects of the plate tectonics theory. We also suggest the importance of future plate tectonic reconstruction of the western Pacific to consider the nature and histories of the Chinese continental shelf of exotic origin as well as the probable transform plate boundary from *100 to*50 Ma. Effort is needed to reveal the true nature and origin of the *88 ± 2 Ma granitic gneisses in Taiwan and the 110–88 Ma granitoids on the Hainan Island. | Yaoling Niu Yi Liu Qiqi Xue Fengli Shao Shuo Chen Meng Duan Pengyuan Guo Hongmei Gong Yan Hu Zhenxing Hu Juanjuan Kong Jiyong Li Jinju Liu Pu Sun Wenli Sun Lei Ye Yuanyuan Xiao Yu Zhang | 2015 | Science Bulletin2015，60，18： | 32 |
| 3 | AFM research on Fe-based nanocrystal crystallization mechanism显示文摘The cross-section pattern of Fe-based alloy ribbon (Fe73.5Cu1Nb3Si13.5B9) annealed at different temperatures was investigated by AFM (atomic force microscope), and the effect mechanism of Nb and Cu in Fe-based alloy ribbon annealing was analyzed with XRD diffraction crystal analysis technique and other research results. New concepts of encapsulated grain, Nb vacancy cluster, Nb-B atom cluster and so on were proposed and used to describe the formation mechanism of α-Fe (Si) nanocrystal. Finally, a three-phase (separation phase, encapsulated phase and nanocrystalline phase) interconnected structure model in Fe-based nanocrystalline alloy was established. | FANG YunZhang WU FengMin ZHENG JinJu SHI FangYe WU WenHui SUN HuaiJun LIN GenJin MAN QiKui HU JuanMei YANG XiaoHong | 2008 | Science China(Technological Sciences)2008，51，1： | 8 |
| 4 | Presenilin 2 deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression显示文摘Accumulating evidence suggests that β-amyloid (Aβ)-induced neuroinflammation plays a prominent and early role in Alzheimer’s disease (AD). In this study, we demonstrated that Presenilin 2 (PS2) deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression both in vitro and in vivo. PS2 knockout mice demonstrated increased cognitive impairments and cerebral injury. PS2 deficiency increased the expression of P2X7 both in neurons and microglial cells.Furthermore, extracellular ATP also increased in both Aβ-treated and untreated PS2 knockout microglial cells. Notably, Aβ-induced classical proinflammatory cytokines such as IL-1β, IL-1α and TNF-α were increased in PS2 knockout microglial cells, suggesting a potential role for PS2 in the regulation of neuroinflammation. The expression of P2X7 clearly increased in PS2 knockdown BV2 cells. Consistent with in vivo data, Aβ-induced IL-1β production was also clearly enhanced in PS2 knockdown BV2 cells. Additionally, expression of the transcription factor Sp1 was increased in PS2 knockdown cells. When we treated PS2 knockdown cells with the specific Sp1 inhibitor MIT, we observed that enhanced P2X7 expression was significantly rescued. Taken together, these data suggests that PS2 plays a protective role during Aβ-induced neuroinflammation and injury through down-regulation of P2X7 expression. | Juliang Qin Xiaoyu Zhang Ziqiang Wang Jinju Li Zhen Zhang Liangcai Gao Hua Ren Min Qian Bing Du | 2017 | Science China(Life Sciences)2017，60，2： | 7 |
| 5 | Inhibition effect of magnetic field on nitrous oxide emission from sequencing batch reactor treating domestic wastewater at low temperature显示文摘This study aims to investigate the effect of a magnetic field on nitrous oxide(N2O)emission from a sequencing batch reactor treating low-strength domestic wastewater at low temperature(10℃).After running for 124 days in parallel,results indicated that the conversion rate of N2O for a magnetic field-sequencing batch reactor(MF-SBR)decreased by34.3%compared to that of a conventional SBR(C-SBR).Meanwhile,the removal efficiencies for total nitrogen(TN)and ammonia nitrogen(NH4-N)of the MF-SBR were 22.4%and 39.5%higher than those of the C-SBR.High-throughput sequencing revealed that the abundances of AOB(Nitrosomonas),NOB(Nitrospira)and denitrifiers(Zoogloea),which could reduce N2O to N2,were promoted significantly in the MF-SBR.Enzyme activities(Nir)and gene abundances(nos Z nir S and nir K)for denitrification in the MF-SBR were also notably higher compared to C-SBR.Our study shows that application of a magnetic field is a useful approach for inhibiting the generation of N2O and promoting the nitrogen removal efficiency by affecting the microbial characteristics of sludge in an SBR treating domestic wastewater at low temperature. | Dan Xu Hongmin Ji Hongqiang Ren Jinju Geng Kan Li Ke Xu | 2020 | Journal of Environmental Sciences2020，32，1： | 7 |
| 6 | Carbon-coated manganese dioxide nanoparticles and their enhanced electrochemical properties for zinc-ion battery applications显示文摘In this study, we report the cost-effective and simple synthesis of carbon-coated α-MnO_2nanoparticles(α-MnO_2@C) for use as cathodes of aqueous zinc-ion batteries(ZIBs) for the first time. α-MnO_2@C was prepared via a gel formation, using maleic acid(C_4H_4O_4) as the carbon source, followed by annealing at low temperature of 270 °C. A uniform carbon network among the α-MnO_2 nanoparticles was observed by transmission electron microscopy. When tested in a zinc cell, the α-MnO_2@C exhibited a high initial discharge capacity of 272 m Ah/g under 66 m A/g current density compared to 213 m Ah/g, at the same current density, displayed by the pristine sample. Further, α-MnO_2@C demonstrated superior cycleability compared to the pristine samples. This study may pave the way for the utilizing carbon-coated MnO_2 electrodes for aqueous ZIB applications and thereby contribute to realizing high performance eco-friendly batteries. | Saiful Islam Muhammad Hilmy Alfaruqi Jinju Song Sungjin Kim Duong Tung Pham Jeonggeun Jo Seokhun Kim Vinod Mathew Joseph Paul Baboo Zhiliang Xiu Jaekook Kim | 2017 | Journal of Energy Chemistry2017，26，4： | 6 |
| 7 | Antigenically dominant proteins within the human liver mitochondrial proteome identified by monoclonal antibodies显示文摘Analysis of the mitochondrial proteome would provide valuable insight into the function of this important organelle, which plays key roles in energy metabolism, apoptosis, free radical production, thermogenesis, and calcium signaling. It could also increase our understanding about the mechanisms that promote mitochondrial disease. To identify proteins that are antigenically dominant in human liver mitochondria, we generated >240 hybridoma cell lines from native mitochondrial proteins after cell fusion, screening, and cloning. Antibodies that recognized mitochondrial proteins were identified by screening human liver cDNA expression libraries. In this study, we identified 6 major antigens that were recognized by at least 2 different monoclonal antibodies (mAbs). The proteins that were antigenically dominant were: acetyl-Coenzyme A acyltransferase 2 (mitochondrial 3-oxoacyl-Coenzyme A thiolase), aldehyde dehydrogenase 1 family member A1, carbamoyl phosphate synthetase 1, dihydrolipoamide S-acetyltransferase (E2 component of pyruvate dehydrogenase complex), enoyl coenzyme A hydratase 1, and hydroxysteroid (11-beta) dehydrogenase 1. We also determined the subcellular localizations of these enzymes within the mitochondria using immunohistocytochemistry. We believe that these well-characterized antibodies will provide a valuable resource for the Human Liver Proteome Project (HLPP), and will make studies aimed at investigating liver mitochondrial function far easier to perform in future. Our results provide strong evidence that, (i) depletion of dominant proteins from liver mitochondrial samples is possible and, (ii) the approaches adopted in this study can be used to explore or validate protein-protein interactions in this important organelle. | JU YanFang YANG JinJu LIU Rong LIU XiaoLan DU XueMei LIU Li CHEN ZhiCheng CHI Jun LIU ShuEr GAO Yuan GAO JianEn JIAO ShunChang HE FuChu SUN QiHong | 2011 | Science China(Life Sciences)2011，54，1： | 6 |
| 8 | Production and emission of phosphine gas from wetland ecosystems显示文摘Phosphine is a part of an atmospheric link of phosphorus cycle on earth, which could be an important pathway for phosphorus transport in environment.Wetland ecosystems are important locations for global biogeochemical phosphorus cycle.In this study, production and emission fluxes of free phosphine from four wetlands types in southern China were observed in different seasons.The results showed that the concentration of phosphine liberated from wetlands was at pg/m3-ng/m3 level.The emission concentrations of different wetlands followed the sequence:paddy field(51.83 ± 3.06) ng/m3 marsh(46.54 ± 20.55) ng/m3 > lake(37.05 ± 22.74) ng/m3 coastal wetland(1.71 ± 0.73) ng/m3, the positive phosphine emission flux occurred in rice paddy field(6.67 ± 5.18) ng/(m2·hr) and marsh(6.23 ± 26.9) ng/(m2·hr), while a negative phosphine flux of(-13.11 ± 35.04) ng/(m2·hr) was observed on the water-air interface of Lake Taihu, suggesting that paddy field and marsh may be important sources for phosphine gas in atmosphere, while lake may be a sink of atmospheric phosphine gas during the sampling period.Atmospheric phosphine levels and emission flux from Yancheng marsh and rice paddy field varied in different seasons and vegetational zones.Both diffusion resistance in aqueous phase and temperature were dominating factors for the production and transportation of phosphine to atmosphere. | Chao Han Xueyuan Gu Jinju Geng Yuning Hong Rui Zhang Xiaorong Wang Shixiang Gao | 2010 | Journal of Environmental Sciences2010，22，9： | 5 |
| 9 | Metal organic framework-combustion: A one-pot strategy to NiO nanoparticles with excellent anode properties for lithium ion batteries显示文摘NiO nanoparticles with average particles size of 30 nm are synthesized using a one-pot metal–organic framework-combustion(MOF-C) technique, for use as an anode material in rechargeable lithium ion batteries(LIBs). The structural and electronic properties of these nanoparticles are studied using various techniques, including powder X-ray diffraction(PXRD), transmission electron microscopy(TEM), scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), and N_2 adsorption/desorption studies. The as-synthesized NiO nanoparticles sustained reversible stable capacities of 748 and 410 mAh/g at applied current densities of 500 and 1000 m A/g, respectively, after 100 cycles. Furthermore, the anode displays a notable rate capability, achieving a stable capacity of ~200 mAh/g at a high current density of10 A/g. These results indicate that the size of the NiO nanoparticles and their high surface area influence their electrochemical properties. Specifically, this combustion strategy is clearly favorable for improving the cyclability and rate capability of various metal oxides in rechargeable battery electrodes. | Vaiyapuri Soundharrajan Balaji Sambandam Jinju Song Sungjin Kim Jeonggeun Jo Pham Tung Duong Seokhun Kim Vinod Mathew Jaekook Kim | 2018 | Journal of Energy Chemistry2018，27，1： | 4 |
| 10 | Phase-pure Na3V2(PO4)2F3 embedded in carbon matrix through a facile polyol synthesis as a potential cathode for high performance sodium-ion batteries显示文摘In this study,a pseudo-layered Na super-ionic conductor of Na3V2(PO4)2F3 (NVPF)/C cathode for sodium-ion batteries is prepared successfully using a facile polyol refluxing process without any impurity phases.The X-ray diffraction and Rietveld refinement results confirm that NVPF possesses tetragonal NASICON-type lattice with a space group of P42/mnm.In this preparative method,polyol is utilized as a solvent as well as a carbon source.The presence of nanosized NVPF particles in the carbon network is confirmed by field-emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM).The existence of carbon is analyzed by Raman scattering and elemental analysis.When applied as a Na-storage material in a potential window of 2.0-4.3 V,the electrode exhibits two flat voltage plateaus at 3.7 and 4.2 V with an electrochemically active V^3+/V^4+ redox couple.In addition,Na3V2(PO4)2F3/C composite achieved a retention capacity of ~ 88% even after 1,500 cycles at 15 C.Moreover,at high current densities of 30 and 50 C,Na3V2(PO4)2F3/C cathode retains the specific discharge capacities of 108.4 and 105.9 mAh·g-1,respectively,revealing the structural stability of the material prepared through a facile polyol refluxing method. | Sohyun Park Jinju Song Seyeon Kim Balaji Sambandam Vinod Mathew Sungjin Kim Jeonggeun Jo Seokhun Kim Jaekook Kim | 2019 | Nano Research2019，12，4： | 4 |
| 11 | HER2-induced metastasis is mediated by AKT/JNK/EMT signaling pathway in gastric cancer显示文摘AIM To investigated the relationships between HER2, c-Jun N-terminal kinase(JNK) and protein kinase B(AKT) with respect to metastatic potential of HER2-positive gastric cancer(GC) cells.METHODS Immunohistochemistry was performed on tissue array slides containing 423 human GC specimens. Using HER2-positve GC cell lines SNU-216 and NCI-N87, HER2 expression was silenced by RNA interference, and the activations of JNK and AKT were suppressed by SP600125 and LY294002, respectively. Transwell assay, Western blot, semi-quantitative reverse transcriptionpolymerase chain reaction and immunofluorescence staining were used in cell culture experiments. RESULTS In GC specimens, HER2, JNK, and AKT activations were positively correlated with each other. In vitro analysis revealed a positive regulatory feedback loop between HER2 and JNK in GC cell lines and the role of JNK as a downstream effector of AKT in the HER2/AKT signaling pathway. JNK inhibition suppressed migratory capacity through reversing EMT and dual inhibition of JNK and AKT induced a more profound effect on cancer cell motility.CONCLUSION HER2, JNK and AKT in human GC specimens are positively associated with each other. JNK and AKT, downstream effectors of HER2, co-operatively contribute to the metastatic potential of HER2-positive GC cells. Thus, targeting of these two molecules in combination with HER2 downregulation may be a good approach to combat HER2-positive GC. | Yiseul Choi Young San Ko Jinju Park Youngsun Choi Younghoon Kim Jung-Soo Pyo Bo Gun Jang Douk Ho Hwang Woo Ho Kim Byung Lan Lee | 2016 | World Journal of Gastroenterology2016，22，41： | 4 |
| 12 | Stimulation of gaseous phosphine production from Antarctic seabird guanos and ornithogenic soils显示文摘Matrix-bound phosphine(MBP) is a general term used to indicate non-gaseous reduced phosphorus compounds that are transformed into phosphine gas upon reaction with bases or acids.Antarctic seabird guanos and ornithogenic soils were used as materials to compare the different digestion methods for transforming matrix-bound phosphine into phosphine gas.The results demonstrated that more phosphine gas in most of Antarctic environmental materials was formed of matrix-bound phosphine by caustic digestion than by acidic digestion.The comparative study on different digestion methods also revealed that the fraction of MBP converted to gaseous phosphine during the digestion depended on the temperature.The optimal digestion temperature was close to 70℃ and the optimal digestion time was about 20 min.Acidic conditions were more favorable for the release of matrix-bound phosphine compared to the neutral conditions.A proper water dilution can increase the production and emission of phosphine from the Antarctic penguin guanos. | ZHU Renbin LIU Yashu SUN Jianjun SUN Liguang GENG Jinju | 2009 | Journal of Environmental Sciences2009，21，2： | 3 |
| 13 | Preliminary Investigation on the Main Fungal Diseases of Sugarcane in Guangxi Province of China显示文摘[Objective] The purpose was to understand species and occurrence status of major fugal diseases in sugarcane cultivation areas of Guangxi in China, so as to provide scientific references for integrated control against sugarcane diseases. [Method] Species and occurrence degrees of major fugal diseases in sugarcane cultivation areas of Guangxi were investigated through randomized surveys, farmer interviews, literature references and location investigations from 2009 to 2011. Diseased sugarcane samples were collected and their species were identified through pathogen isolated culture and other relevant methods. [Result] Thirteen species of fungal diseases were identified in the survey, including pineapple disease [Thielaviopsis paradoxa (de Seynes) V. Hohnel], smut(Ustilago scitaminea Sydow), top rot disease (Fusarium moniliforme Sheldon), rust (Puccinia melanocephala H.﹠P. Syd.), leaf scald disease (Stagonospora sacchari Lo et Ling), red rot disease (Colletotrichum falcatum Went), zonate spot disease (Phyllosticta saccharicola P. Henn.), leaf red spot disease [Pellicularia sasakii (Shirai) Ito], white rash disease (Elsinoe sacchari L.), eye spot [Helminthosporium sacchari (Breda de Haan) Butler], yellow spot [Mycovellosiella koepkei (kruger) Deighton], brown stripe [Bipolaris stenospilum (Drechs.) Shoem.]and brown spot (Cercospora longipes Butler). Smut, rust, top rot, and pineapple disease were the most rampantly detrimental to quality and yield of sugarcane. [Conclusion] Smut is the most serious sugarcane disease; it is urgent to breed sugarcane varieties with high resistance and excellent agronomic characters to replace current sugarcane varieties susceptible to diseases. | Wei Jinju Deng Zhanyun Huang Chenghua Huang Weihua Yan Meixin Liu Haibin Tang Hongqin | 2013 | Plant Diseases and Pests2013，4，1： | 3 |
| 14 | The determination of atmospheric phosphine in Ny-lesund显示文摘Phoshpine (PH3), a volatile and toxic gas, has been proved to commonly exist in the environment.The determination of gaseous phosphine and its emission fluxes in Ny-lesund is reported in this paper.Results showed that gaseous phosphine exist in Arctic atmosphere commonly and the concentration of phosphine ranged from 16.3-600.2 ng/m3, with the maximum concentration of phosphine in tundra areas and the minimum in surface air of ocean.The concentration of phosphine ranged from 65.79-1259 ng/m3 in colliery atmosphere at different altitudes and the maximum was found in the center of colliery.Emission fluxes of phosphine were different in various Arctic areas.Emission fluxes of phosphine from protected areas, with average concentration of 32.13±5.353 ng m–2 h–1, were higher than from other areas.And the flux of phosphine from ocean was lower. | ZHANG Rui WU Min WANG Qiang GENG JinJu YANG XiaoDi | 2010 | Chinese Science Bulletin2010，55，16： | 2 |
| 15 | The effect of anodizing temperature on the structure and electrical properties of Al-Ti composite oxide film显示文摘The Al-Ti composite oxide films with high dielectric constant were prepared by hydrolysis precipitation and anodizing. The growth, structure and electrical properties of the Al-Ti composite oxide films formed at different anodizing temperatures from 25℃ to 85℃ have been studied by dissolution of anodic oxide films, Auger electron spectroscopy (AES), and electrical measurements. With the anodizing temperature increasing, the film growth rate increases, the structure of two layers in the Al-Ti composite oxide film converts into three layers, I-V characteristics change evidently, and the specific capacitance achieves a peak value at about 75℃. The local breakdown in the composite oxide films formed at 50℃ occurs obviously, which may be contributed to the lowest leakage current and the highest withstanding voltage. | CHEN Jinju YANG Bangchao JIANG Meilian FENG Zhesheng | 2005 | Science China(Technological Sciences)2005，48，6： | 2 |
| 16 | High quality p-type ZnO film growth by a simple method and its properties显示文摘P-type ZnO:N films have been grown successfully by chemical vapor deposition (CVD) using Zn4(OH)2(O2CCH3)6·2H2O as the solid source material and ZnNO3 as the doping source material. XPS, Hall-effect measurement and PL spectra were employed to analyze the structural, electrical and optical properties and study the influence of substrate temperature on the film. Results showed that with a lower substrate temperature, the film exhibited p-type conduction and its resistivity decreased when the substrate temperature increased. When the substrates temperature was 400℃, p-type ZnO films were obtained with carrier concentration of +5.127×1017 cm?3, resistivity of 0.04706 ?·cm and Hall mobility of 259 cm2/(V·s); they still exhibited p-type conduction after a month. When the substrate tem- perature was too high, the film was transformed from p-type to n-type conduction. | MAO FeiYan DENG Hong DAI LiPing CHEN JinJu YUAN ZhaoLin LI Yan | 2008 | Chinese Science Bulletin2008，53，17： | 2 |
| 17 | A high-quality sponge gourd(Luffa cylindrica)genome显示文摘Sponge gourd(Luffa cylindrica)is an important cultivated vegetable and medicinal plant in the family Cucurbitaceae.In this study,a draft genome sequence of the sponge gourd inbred line P93075 was analyzed.Using Illumina,PacBio,and 10×Genomics sequencing techniques as well as new assembly techniques such as FALCON and chromatin interaction mapping(Hi-C),a chromosome-scale genome of approximately 656.19 Mb,with an N50 scaffold length of 48.76 Mb,was generated.From this assembly,25,508 protein-coding gene loci were identified,and 63.81%of the whole-genome consisted of transposable elements,which are major contributors to the expansion of the sponge gourd genome.According to a phylogenetic analysis of conserved genes,the sponge gourd lineage diverged from the bitter gourd lineage approximately 41.6 million years ago.Additionally,many genes that respond to biotic and abiotic stresses were found to be lineage specific or expanded in the sponge gourd genome,as demonstrated by the presence of 462 NBS-LRR genes,a much greater number than are found in the genomes of other cucurbit species;these results are consistent with the high stress resistance of sponge gourd.Collectively,our study provides insights into genome evolution and serves as a valuable reference for the genetic improvement of sponge gourd. | Haibin Wu Gangjun Zhao Hao Gong Junxing Li Caixia Luo Xiaoli He Shaobo Luo Xiaoming Zheng Xiaoxi Liu Jinju Guo Junqiu Chen Jianning Luo | 2020 | Horticulture Research2020，7，1： | 2 |
| 18 | ANALYSIS OF A CRACK IN A FUNCTIONALLY GRADED STRIP WITH A POWER FORM SHEAR MODULUS显示文摘The plane strain problem of a crack in a functionally graded strip with a power form shear modulus is studied.The governing equation in terms of Airy’s stress function is solved exactly by means of Fourier transform.The mixed boundary problem is then reduced to a system of singular integral equations and is solved numerically to obtain the stress intensity factor at crack-tip.The maximum circumferential stress criterion and the strain energy density criterion are both employed to predict the direction of crack initiation.Numerical examples are given to show the influence of the material gradation models and the crack sizes on the mode-I and mode-II stress intensity factors.The dependence of the critical kink-angle on the crack size is examined and it is found that the crack kink-angle decreases with the increase of the normalized crack length, indicating that a longer crack tends to follow the original crack-line while it is much easier for a shorter crack to deviate from the original crack-line. | Jinju Ma Zheng Zhong Chuanzeng Zhang | 2009 | Acta Mechanica Solida Sinica2009，22，5： | 2 |
| 19 | Study on four polymorphs of bifendate based on X-ray crystallography显示文摘Bifendate, a synthetic anti-hepatitis drug, exhibits polycrystalline mode phenomena with 2polymorphs reported(forms A and B). Single crystals of the known crystalline form B and 3 new crystallosolvates involving bifendate solvated with tetrahydrofuran(C), dioxane(D), and pyridine(E) in a stoichiometric ratio of 1:1 were obtained and characterized by X-ray crystallography, thermal analysis,and Fourier transform infrared(FT-IR) spectroscopy. The differences in molecular conformation,intermolecular interaction and crystal packing arrangement for the four polymorphs were determined and the basis for the polymorphisms was investigated. The rotation of single bonds resulted in different orientations for the biphenyl, methyl ester and methoxyl groups. All guest solvent molecules interacted with the host molecule via an interesting intercalative mode along the [1 0 0] direction in the channel formed by the host molecules through weak aromatic stacking interactions or non-classical hydrogen bonds, of which the volume and planarity played an important role in the intercalation of the host with the guest. The incorporation of solvent-augmented rotation of the C–C bond of the biphenyl group had a striking effect on the host molecular conformation and contributed to the formation of bifendate polymorphs. Moreover, the simulated powder X-ray diffraction(PXRD) patterns for each form were calculated on the basis of the single-crystal data and proved to be unique. The single-crystal structures of the four crystalline forms are reported in this paper. | Jinju Nie Dezhi Yang Kun Hu Yang Lu | 2016 | Acta Pharmaceutica Sinica B2016，6，3： | 2 |
