| 2 | Synthesis of CNT film on the surface of micro-pyramid array and its intense pulsed emission characteristics显示文摘We developed a new scheme to suppress the electric-field-screening effect in high growth density of a carbon nanotube(CNT) film during its intense pulsed emission.We synthesize the CNT film on a tridimensional surface(t-CNT film).The tridimensional surface includes wet etched silicon pyramids,and the Ni layer is electroless plated thereon.The intense pulsed emission characteristics of the t-CNT and planar-grown CNT(p-CNT) films were measured using a diode structure in single-pulse mode.The even turn-on field decreased from 5.5 V/μm for p-CNTs to 2.8 V/m for t-CNTs,and the peak emission current increased from 232 A for p-CNTs to 324 A for t-CNTs at a peak field intensity ~12.2 V/m.The peak current of the t-CNT film increased by ~39.7% over the p-CNT film.It is clear that the micro-pyramid array can effectively suppress the field screening effect to improve the electron-emission of CNT films. | ZENG FanGuang LI Xin LIU WeiHua QIAO ShuZhen MA HuaLi ZHANG Rui XIA LianSheng CHEN Yi LIU XingGuang ZHANG Huang | 2012 | Chinese Science Bulletin2012，57，14： | 10 |
| 3 | Rescued virus from infectious cDNA clone of rabbit hemorrhagic disease virus is adapted to RK13 cells line显示文摘Based on the infectious full-length cDNA clone of rabbit hemorrhagic disease virus (RHDV), the in vitro transcripts are introduced into RK13 cells. 12 h later, CPE could be observed clearly, and virual antigen could also be detected by IFA. The titre of the recovered virus is 104.6/mL. Immune electron micro-scopic observation of the virus particles revealed that the particles were rotund with a diameter of about 30 nm. Besides, virus titre quantification obtained by qRT-PCR showed a correlation between time from infection and virus titre. All these results showed that we have recovered RHDV from RK13 cells by re-verse genetics technology successfully, and this would be very useful in studies of the antigenicity, virulence, pathogenesis, maturation and new type vaccines of RHDV. | LIU Guangqing NI Zheng YUN Tao ZHANG Yuying DU Qingyun SHENG Zutian LIANG Huali HUA Jionggang LI Shuangmao Chen Jianping | 2006 | Chinese Science Bulletin2006，51，14： | 9 |
| 4 | Improvement in the intense pulsed emission stability of grown CNT films via an electroless plated Ni layer显示文摘Carbon nanotube(CNT)films were grown on silicon wafers with and without a nickel layer(Si-CNT and Ni-CNT)via the pyrolysis of iron phthalocyanine.The nickel layer was prepared using the electroless plating method.To study the emission stability of Si-CNT and Ni-CNT cathodes during intense pulsed emission,emission characteristics were measured repeatedly with a diode structure using a Marx generator as a voltage source.For the peak values of the pulsed voltage,which were in the range between 1.62-1.66 MV(corresponding to electric field intensities between 11.57-11.85 V/μm),the first cycle emission current was 109.4 A for Si-CNT and 180.5 A for Ni-CNT.By comparing the normalized emission currents of the Si-CNT and Ni-CNT cathodes,the improvement in the emission stability can be easily quantified.The number of emission cycles necessary for the peak current to decay from 100%to 50%increased from^3 for Si-CNT to^11 for a Ni-CNT film. | ZENG FanGuang LI Xin LIU WeiHua QIAO ShuZhen MA HuaLi ZHANG Rui XIA LianSheng CHEN Yi LIU XingGuang ZHANG Huang | 2011 | Chinese Science Bulletin2011，56，22： | 7 |
| 5 | Effects of Flexibility and Suspension Configuration of Main Shaft on Dynamic Characteristics of Wind Turbine Drivetrain显示文摘The current research of wind turbine drivetrain is mainly concentrated in dynamic characteristics of gearbox with a specific suspension of main shaft, such as one-point and two-point suspension. However, little attention is paid to the e ects of these suspension configurations on the dynamic responses of wind turbine gearbox. This paper investigates the influences of suspension configurations of main shaft on the dynamic characteristics of drivetrain. For evaluating the dynamic behaviors of drivetrain with multi-stage transmission system more realistically, a dynamic modeling approach of drivetrain is proposed based on Timoshenko beam theory and Lagrange's equation. Considering the flexibility and di erent suspension configurations of main shaft, time-varying mesh sti ness excitation, time-varying transmission error excitation and gravity excitation, etc., a three-dimensional dynamic model of drivetrain is developed, and the dynamic responses of drivetrain are investigated. Results show that with the one-point suspension of main shaft, the resonance frequencies in gearbox, especially at the low-speed stage, obviously shift to the higher frequency range compared to the gearbox without main shaft, but this trend could be inversed by increasing main shaft length. Meanwhile, the loads in main shaft, main shaft bearing and carrier bearing are greatly sensitive to the main shaft length. Hence, the load sharing is further disrupted by main shaft, but this e ect could be alleviated by larger load torque. Comparing to the one-point suspension of main shaft, there occurs the obvious load reduction at the low-speed stage with two-point suspension of main shaft. However, those advantages greatly depend on the distance between two main bearings, and come at the expense of increased load in upwind main shaft unit and the corresponding main bearing. Finally, a wind field test is conducted to verify the proposed drivetrain model. This study develops a numerical model of drivetrain which is able to evaluate the e ects of di erent suspension configurations of main shaft on gearbox. | Jianjun Tan Caichao Zhu Chaosheng Song Huali Han Yao Li | 2019 | Chinese Journal of Mechanical Engineering2019，32，2： | 7 |
| 6 | Gene Cloning and Expression of the Pyrroline-5-carboxylate Reductase Gene of Perennial Ryegrass(Lolium perenne)显示文摘Salt and drought limit the range of applications of perennial ryegrass(Lolium perenne L.), which is one of the important turf and forage grasses. Previous studies have suggested that pyrroline-5-carboxylate reductase(P5CR) might play a central role in proline accumulation in plants that are responsive to stresses. In the present study, the Lolium perenne L. pyrroline-5-carboxylate reductase(LpP 5CR) gene was cloned from leaves of the cultivar ‘Derby' using the RACE technique. The full-length LpP 5CR gene was 1 047 bp in length, which comprised an open reading frame(ORF) of 840 bp in size. Sequence alignment revealed that the putative Lp P5 CR had a 94.3% similarity to Ta P5 CR. q RT-PCR displayed that the mR NA levels of the LpP 5CR gene were almost the same as that in the roots, stems, and leaves of perennial ryegrass seedlings subjected to normal condition or NaC l treatment for 1 h. Moreover, the transcription level of LpP 5CR was up- or down- regulated with Na Cl, polyethylene glycol(PEG), cold, or abscisic acid(ABA) treatment for 3 to 48 h. In addition, confocal microscopy localized the GFP-Lp P5 CR fusion protein to the cytoplasm of onion epidermal cells. These findings suggest that LpP 5CR encodes a cytoplasmic P5 CR protein that plays an important role in the response of perennial ryegrass to various stresses. | CAO Li WEI Shuqiang HAN Lei QIAN Yongqiang ZHANG Huali XIN Haibo SUN Zhenyuan | 2015 | Horticultural Plant Journal2015，1，2： | 7 |
| 7 | The calcium-dependent protein kinase ZmCDPK7 functions in heat-stress tolerance in maize显示文摘Global warming poses a serious threat to crops.Calcium-dependent protein kinases(CDPKs)/CPKs play vital roles in plant stress responses,but their exact roles in plant thermotolerance remains elusive.Here,we explored the roles of heat-induced ZmCDPK7 in thermotolerance in maize.ZmCDPK7-overexpressing maize plants displayed higher thermotolerance,photosynthetic rates,and antioxidant enzyme activity but lower H2 O2 and malondialdehyde(MDA)contents than wild-type plants under heat stress.ZmCDPK7-knockdown plants displayed the opposite patterns.ZmCDPK7 is attached to the plasma membrane but can translocate to the cytosol under heat stress.ZmCDPK7 interacts with the small heat shock protein sHSP17.4,phosphorylates sHSP17.4 at Ser-44 and the respiratory burst oxidase homolog RBOHB at Ser-99,and up regulates their expression.Site-directed mutagenesis of sHSP17.4 to generate a Ser-44-Ala substitution reduced ZmCDPK7’s enhancement of catalase activity but enhanced ZmCDPK7’s suppression of MDA accumulation in heat-stressed maize protoplasts.sHSP17.4,ZmCDPK7,and RBOHB were less strongly upregulated in response to heat stress in the abscisic acid-deficient mutant vp5 versus the wild type.Pretreatment with an RBOH inhibitor suppressed sHSP17.4 and ZmCDPK7 expression.Therefore,abscisic acid-induced ZmCDPK7 functions both upstream and downstream of RBOH and participates in thermotolerance in maize by mediating the phosphorylation of sHSP17.4,which might be essential for its chaperone function. | Yulong Zhao Hanwei Du Yankai Wang Huali Wang Shaoyu Yang Chaohai Li Ning Chen Hao Yang Yihao Zhang Yulin Zhu Luyao Yang Xiuli Hu | 2021 | Journal of Integrative Plant Biology2021，63，3： | 6 |
| 8 | The efficacy and safety of nimodipine in acute ischemic stroke patients with mild cognitive impairment: a double-blind, randomized,placebo-controlled trial显示文摘Nimodipine might be effective in subcortical vascular dementia(VaD). Its benefit in preventing further cognitive decline in patients with acute ischemic stroke(AIS) and vascular mild cognitive impairment(VaMCI) remains to be established. In this multicenter, double-blind trial, we randomly assigned 654 eligible patients to nimodipine 30 mg three times a day or placebo. The primary outcome was any cognitive decline defined by the changes on the Mini-Mental State Examination(DMMSE à3) or vascular AD assessment scale cognitive subscale(DADAS-cog ! 4) at 6 months. Secondary outcomes included any distribution shift of DADAS-cog, DMMSE or cognitive improvement defined by DADAS-cog à2, or DMMSE ! 0. The primary outcome in the nimodipine group and placebo group were similar for DMMSE à3(4.18% and 7.22%, respectively, P = 0.15) and DADAS-cog ! 4(8.36% and 8.93% respectively,P = 0.88). The distribution shift of DADAS-cog and DMMSE differed significantly between the two groups(P = 0.03 and P = 0.05 respectively). Cognitive improvement occurred in 55.4% in the nimodipine group and 43.6% in the placebo group measured by DADAS-cog à2(Odds Ratio, 1.54; 95% confidence interval[CI] 1.10–2.14, P < 0.01) or 84.0% and 74.6% respectively by DMMSE ! 0(Odds Ratio, 1.79; 95% CI 1.18–2.70, P < 0.01). Nimodipine was associated with better cognitive function in the memory domain. The adverse events rate was similar in two groups. This study is registered with ClinicalTrials.gov,NCT01220622. Nimodipine did not show benefit to prevent cognitive decline in AIS patients with VaMCI, but improved cognition moderately, especially measured in the memory domain. | Huaguang Zheng Yilong Wang Anxin Wang Hao Li David Wang Xingquan Zhao Penglian Wang Haipeng Shen Lijun Zuo Yuesong Pan Zixiao Li Xia Meng Xianwei Wang Weixiong Shi Yi Ju Liping Liu Kehui Dong Chunxue Wang Rubo Sui Rong Xue Xiaoping Pan Xiaoyua Niu Benyan Luo Yi Sui Huali Wang Tao Feng Yongjun Wang | 2019 | Science Bulletin2019，64，2： | 5 |
| 9 | Abscisic acid negatively regulates post-penetration resistance of Arabidopsis to the biotrophic powdery mildew fungus显示文摘Pytohormone abscisic acid(ABA) plays important roles in defense responses.Nonetheless,how ABA regulates plant resistance to biotrophic fungi remains largely unknown.Arabidopsis ABA-deficient mutants,aba2-1 and aba3-1,displayed enhanced resistance to the biotrophic powdery mildew fungus Golovinomyces cichoracearum.Moreover,exogenously administered ABA increased the susceptibility of Arabidopsis to G.cichoracearum.Arabidopsis ABA perception components mutants,abil-1 and abi2-1,also displayed similar phenotypes to ABA-deficient mutants in resistance to G.cichoracearum.However,the resistance to G.cichoracearum is not changed in downstream ABA signaling transduction mutants,abi3-1,abi4-1,and abi5-1.Microscopic examination revealed that hyphal growth and conidiophore production of G.cichoracearum were compromised in the ABA deficient mutants,even though pre-penetration and penetration growth of the fungus were not affected.In addition,salicylic acid(SA) and MPK3 are found to be involved in ABA-regulated resistance to G.cichoracearum.Our work demonstrates that ABA negatively regulates post-penetration resistance of Arabidopsis to powdery mildew fungus G.cichoracearum,probably through antagonizing the function of SA. | Xiang Xiao Xi Cheng Kangquan Yin Huali Li Jin-Long Qiu | 2017 | Science China(Life Sciences)2017，60，8： | 4 |
| 10 | Variation of Thornthwaite Moisture Index in Hengduan Mountains, China显示文摘The Thornthwaite moisture index, an index of the supply of water(precipitation) in an area relative to the climatic demand for water(potential evapotranspiration), was used to examine the spatial and temporal variation of drought and to verify the influence of environmental factors on the drought in the Hengduan Mountains, China. Results indicate that the Thornthwaite moisture index in the Hengduan Mountains had been increasing since 1960 with a rate of 0.1938/yr. Annual Thornthwaite moisture index in Hengduan Mountains was between –97.47 and 67.43 and the spatial heterogeneity was obvious in different seasons. Thornthwaite moisture index was high in the north and low in the south, and the monsoon rainfall had a significant impact on its spatial distribution. The tendency rate of Thornthwaite moisture index variation varied in different seasons, and the increasing trends in spring were greater than that in summer and autumn. However, the Thornthwaite moisture index decreased in winter. Thornthwaite moisture index increased greatly in the north and there was a small growth in the south of Hengduan Mountains. The increase of precipitation and decrease of evaporation lead to the increase of Thornthwaite moisture index. Thornthwaite moisture index has strong correlation with vegetation coverage. It can be seen that the correlation between Normalized Difference Vegetation Index(NDVI) and Thornthwaite moisture index was positive in spring and summer, but negative in autumn and winter. Correlation between Thornthwaite moisture index and relative soil relative moisture content was positive in spring, summer and autumn, but negative in winter. The typical mountainous terrain affect the distribution of temperature, precipitation, wind speed and other meteorological factors in this region, and then affect the spatial distribution of Thornthwaite moisture index. The unique ridge-gorge terrain caused the continuity of water-heat distribution from the north to south, and the water-heat was stronger than that from the east to west part, and thus determined the spatial distribution of Thornthwaite moisture index. The drought in the Hengduan Mountains area is mainly due to the unstable South Asian monsoon rainfall time. | ZHU Guofeng QIN Dahe TONG Huali LIU Yuanfeng LI Jiafang CHEN Dongdong WANG Kai HU Pengfei | 2016 | Chinese Geographical Science2016，26，5： | 4 |
| 11 | Enhanced photocatalytic degradation of organic contaminants over CaFe_(2)O_(4) under visible LED light irradiation mediated by peroxymonosulfate显示文摘A simple sol-gel approach is proposed herein to fabricate CaFe_(2)O_(4)for the degradation of various organic pollutants(rhodamine B(RhB),tetracycline hydrochloride,humic acid,and methylene orange)under LED light irradiation mediated by peroxymonosulfate(PMS).The results indicate that the calcination temperature can significantly influence the performance of CaFe_(2)O_(4)for PMS activation,and the CaFe_(2)O_(4)sample obtained at 800℃(CaFe_(2)O_(4)-800)exhibits the best efficiency in degrading RhB,which is much higher than that of Fe_2o_(3)-800.This can be attributed to the efficient separation of photogenerated electrons(e^(-))and holes(h^(+))by PMS,which is validated by transient photocurrent response and photoluminescence measurements.Results from density functio nal theo ry calculations indicate that the valence band of CaFe_(2)O_(4)-800 exhibits a high concentration of carriers and weak localization of electrons,which are favorable for PMS activation.Radical scavenging results confirm that h^(+)and O_(2)^(·-)are the dominant reactive species.Moreover,CaFe_(2)O_(4)-800 not only demonstrated a stable performance during eight cycling runs with negligible iron leaching but also exhibited excellent degradation efficiency under natural water and sunlight.Finally,the mechanism and pathway of RhB degradation by the CaFe_(2)O_(4)-800/PMS/LED system are also proposed.This work presents the enormous prospect of CaFe_(2)O_(4)as an environmentally benign photocatalyst for PMS activation. | Sheng Guo Zhixiong Yang Huali Zhang Wei Yang Jun Li Kun Zhou | 2021 | Journal of Materials Science & Technology2021，，3： | 3 |

| 13 | The characteristics of oasis urban expansion and drive mechanism analysis:a case study on Ganzhou District in Hexi Corridor,China显示文摘Ganzhou District is an oasis city in the Zhangye Municipality of Gansu Province,China.Based on multi-temporal TM and ETM satellite remote sensing data in 1985,1996,2000,and 2012,and by using corrected figures of land use status over the same periods,the spatial area of Ganzhou District since 1985 was extracted with statistical methods,and urban spatial expansion was measured by quantitative research methods.The characteristics of spatial expansion of Ganzhou District were analyzed by urban expansion rate,expansion intensity index,compactness,fractal dimension,and the city center shift method.The results showed that the built-up area of Ganzhou District increased by 3.46 times during 1985–2012.The expansion in 1985–1996 was slow,during 1996–2000 it was rapid,and during 2000–2012 it was at a high speed.This city mainly expanded to the northeast and northwest.Government decision making had a decisive influence on urban expansion.Initially the expansion was uniform,but later the local transportation,economy,resources,population,and national policies factors had an obvious influence on urban expansion. | HuaLi Tong PeiJi Shi GuoFeng Zhu April Pearson QianGuo Li YuanFeng Liu HaiLong Liu | 2015 | Research in Cold and Arid Regions2015，7，3： | 2 |

| 15 | Biodegradable magnesium alloy with eddy thermal effect for effective and accurate magnetic hyperthermia ablation of tumors显示文摘Magnetic hyperthermia therapy(MHT)is able to ablate tumors using an alternating magnetic field(AMF)to heat up magnetocaloric agents(e.g.magnetic nanoparticles)administered into the tumors.For clinical applications,there is still a demand to find new magnetocaloric agents with strong AMF-induced heating performance and excellent biocompatibility.As a kind of biocompatible and biodegradable material,magnesium(Mg)and its alloys have been extensively used in the clinic as an implant metal.Herein,we discovered that the eddy thermal effect of the magnesium alloy(MgA)could be employed for MHT to effectively ablate tumors.Under low-field-intensity AMFs,Mg A rods could be rapidly heated,resulting in a temperature increase in nearby tissues.Such AMF-induced eddy thermal heating of MgA could not only be used to kill tumor cells in vitro,but also be employed for effective and accurate ablation of tumors in vivo.In addition to killing tumors in mice,we further demonstrated that VX2 tumors of much larger sizes growing in rabbits after implantation of Mg A rods could also be eliminated after exposure to an AMF,illustrating the ability of MgA-based MHT to kill large-sized tumors.Moreover,the implanted MgA rods showed excellent biocompatibility and~20%of their mass was degraded within three months.Our work thus discovered for the first time that non-magnetic biodegradable Mg A,an extensively used implant metal in clinic,could be used for effective magnetic thermal ablation of tumors under a low-field-intensity AMF.Such a strategy could be readily translated into clinical use. | Nailin Yang Fei Gong Liang Cheng Huali Lei Wei Li Zongbin Sun Caifang Ni Zhanhui Wang Zhuang Liu | 2021 | National Science Review2021，8，1： | 1 |
