2Effects of Nb Content on Yield Strength of NiTiNb Alloys in Martensite State显示文摘采用SEM,EDS,DSC和拉伸实验等方法测试两种单相NiTiNb合金(Ni50Ti48Nb2和Ni49.5Ti46.5Nb4),以分析Nb原子在NiTi相中的固溶量对合金由马氏体自协作而导致的屈服强度的影响。根据实验结果,推断Nb原子固溶量对NiTi相的屈服强度负相关。本次研究与前期实验结果相比较,提出了一个有关Nb含量对NiTiNb合金的马氏体态屈服强度有两个共同作用机制的假设.一个是Nb原子固溶弱化机制,另一个是Nb相复合强化机制。这个假设比较圆满的解释了(NiTi)50-0.5xNbx合金的马氏体态屈服强度随Nb含量的增加,先降低然后再大幅增加的实验结果。Xiao Fu Ma Guojun Zhao Xinqing Xu Huibin 2009Chinese Journal of Aeronautics2009,22,6:11
3Coupling effects of tungsten and molybdenum on microstructure and stress-rupture properties of a nickel-base cast superalloy显示文摘In order to comprehensively understand the forming mechanism of abnormal phases solidified in a nickel-base cast superalloy with additives of tungsten and molybdenum, the coupling effects of W and Mo on the microstructure and stress-rupture properties were investigated in this paper. The results indicated that the precipitation of primary α-(W, Mo) phase depended tremendously on the amount of W and Mo addition. When the total amount of W and Mo was greater than 5.79 at%, α-(W, Mo) phase became easily precipitated in the alloy.With increasing of Mo/W ratio, the dendrite-like α-(W, Mo) phases were apt to convert into small bars or blockylike phases at the vicinities of γ′/γ eutectic. The morphological changes of α-(W, Mo) phase can be interpreted as the non-equilibrium solidification of W and Mo in the alloy. Since the large sized α-(W, Mo) phase has detrimental effects on stress-rupture properties in as-cast conditions, secondary cracks may mainly initiate at and then propagate along the interfaces of brittle phases and soft matrix. During exposing at 1100 ℃ for 1000 h, the α-(W, Mo) phases transformed gradually into bigger and harder M_6C carbide, which results in decreasing of stress-rupture properties of the alloy. Finally, the alloy with an addition of 14W-1Mo(wt%) maintained the longest stress lives at high temperatures and therefore it revealed the best microstructure stability after 1100 ℃/1000 h thermal exposure.Tongjin Zhou Wei Feng Huibin Zhao Yu Meng Huaxia Zhang Hongsheng Ding Zichen Wang 2018Progress in Natural Science:Materials International2018,28,1:7
4Nanosecond photoelectric effects in all-oxide p-n junction of La_(0.9)Sr_(0.1)MnO_(3)/SrNb_(0.01)Ti_(0.99)O_(3)显示文摘Nanosecond (ns) photoelectric effects have been observed in all-oxide p-n junctions of La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 for the first time. The rise time was about 23 ns and the full width at half maximum was about 125 ns for the open-circuit photovoltaic pulse when the La0.9Sr0.1MnO3 thin film in the p-n junction was irradiated by a laser of ~20 ns pulse duration and 308 nm wavelength. The photovoltaic sensitivity was 80 mV/mJ for a 308 nm laser pulse.HUANG Yanhong L(U) Huibin HE Meng ZHAO Kun CHEN Zhenghao CHENG Bolin ZHOU Yueliang JIN Kuijuan DAI Shouyu YANG Guozhen 2005Science China(Physics,Mechanics & Astronomy)2005,48,3:4
5CPPU may induce gibberellin-independent parthenocarpy associated with PbRR9 in‘Dangshansu’pear显示文摘Parthenocarpy is a valuable trait in self-incompatible plants,such as pear.N-(2-chloro-4-pyridyl)-N’-phenylurea(CPPU),a synthetic cytokinin analog,can induce parthenocarpy in pear(Pyrus spp.),but the mechanism of induction is unclear.To investigate the role of gibberellin in CPPU-induced parthenocarpy in pear,CPPU supplemented with paclobutrazol(PAC)was sprayed onto‘Dangshansu’pear.We found that the fruit set rate of pear treated with CPPU supplemented with PAC was identical to that in a CPPU-alone treatment group.In regard to cell development,CPPU mainly promoted hypanthium cell division and expansion,and PAC application had no influence on CPPU-induced cell development.RNA sequencing revealed that gibberellin 20 oxidase and gibberellin 3 oxidase genes were not differentially expressed following CPPU treatment.According to the analysis of fruit phytohormone content,the CPPU treatments did not induce gibberellin biosynthesis.These results suggest that CPPU-induced parthenocarpy may be gibberellin independent in‘Dangshansu’pear.After CPPU treatment,the indole acetic acid(IAA)content in fruit was significantly increased,and the abscisic acid(ABA)content was significantly decreased.Similarly,RNA sequencing revealed that many genes involved in the auxin and ABA pathways were significantly differentially expressed in the CPPU treatment groups;among them,indole-3-pyruvate monooxygenase(YUCCA)was significantly upregulated and 9-cis-epoxycarotenoid dioxygenase(NCED)was significantly downregulated.IAA and ABA may thus play important roles in CPPU-induced parthenocarpy.PbTwo-component response regulator9(PbRR9),PbYUCCA4,and PbNCED6 were then selected to further elucidate the mechanism of CPPU-induced parthenocarpy.A yeast one-hybrid assay indicated that PbRR9 can combine with the PbYUCCA4 and PbNCED6 promoters.Dual luciferase assays revealed that PbRR9 can promote and repress the activities of the PbYUCCA4 and PbNCED6 promoters,respectively.After the transient expression of PbRR9 in fruits,PbYUCCA4 expression was significantly upregulated,and PbNCED6 expression was significantly downregulated.This study uncovered a CPPU-induced parthenocarpy mechanism that is different from that in tomato.CPPU may upregulate PbYUCCA4 and downregulate PbNCED6 by upregulating PbRR9,thereby increasing IAA content and decreasing ABA content to ultimately induce parthenocarpy in‘Dangshansu’pear.However,because only a single time point was used and because‘botanical’and‘accessory’fruits have different structures,this conclusion is still preliminary.Liu Cong Ting Wu Hanting Liu Huibin Wang Haiqi Zhang Guangping Zhao Yao Wen Qianrong Shi Lingfei Xu Zhigang Wang 2020Horticulture Research2020,7,1:4
6A study on surface symmetry and interfacial enhancement of SrTiO_3 by second harmonic generation显示文摘The symmetry of the surfaces of SrTiO3and slightly Nb-doped SrTiO3crystals was investigated by the optical reflected second harmonic generation technique.The good agreement between experimental and theoretical results of the second harmonic intensity dependence on the azimuth angle indicates that the SrTiO3(001)surface is with 4mm symmetry and the Nb-doped SrTiO3(111)surface with 3m symmetry.The measurements of the polarization dependent second harmonic intensity confirm that conclusion.The enhancement of the surface polarization in the structure of SrTiO3capped La0.9Sr0.1MnO3films compared with that in the La0.9Sr0.1MnO3films has been obtained.ZHAO RuiQiang JIN KuiJuan GUO HaiZhong LU HuiBin YANG GuoZhen 2013Science China(Physics,Mechanics & Astronomy)2013,56,12:3
7Phase Equilibria in Nb-Si-Mo Ternary Alloys at 1273 K and 2073 K显示文摘Phase equilibrium in Nb-Si-Mo ternary alloys (<37.5 at.% Si) at 1 273 K and 2 073 K is investigated by using X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The partial isothermal section at 1 273 K, which contains four single-phase regions, five two-phase regions and two three-phase regions, is basically the same as that at 1 973 K. However, when the temperature increases to 2 073 K, the three-phase region of Nbss+α-(Nb(Mo))5Si3+β-(Nb,Mo)5Si3 obvi-ously moves towards the Nb-rich corner. This suggests that Nb-Si-Mo ternary alloys remain stable at least up to 1 973 K.Huang Qiang Ma Chaoli Zhao Xinqing Xu Huibin 2008Chinese Journal of Aeronautics2008,21,5:3
8The selective deposition of Fe species inside ZSM-5 for the oxidation of cyclohexane to cyclohexanone显示文摘The design of efficient iron-based catalysts remains a great challenge for selective cyclohexane oxidation to cyclohexanone under mild conditions.Because of the complex distribution of iron location on the support,the selectivity is always low.Here,we report a general strategy to selectively deposit highly-dispersed FeO_(x) into the micropore of ZSM-5 by atomic layer deposition(ALD).The framework of ZSM-5 and the Bronsted acid sites are intact during ALD,and the Fe species are selectively deposited onto the defect and Lewis acid sites of ZSM-5.Besides,more Fe–O–Si bonds are formed over FeO_(x)/ZSM-5 with a low loading of Fe,while FeO_(x) nanoparticles are generated at high Fe loading.They cannot be realized by the traditional solution method.The obtained FeO_(x)/ZSM-5 catalysts perform high selectivity of cyclohexanone(92%–97%),and ALD cycle numbers of FeO_(x) control the activity.Compared with the Fe nanoparticles,the Fe–O–Si species performs higher turnover frequency and stability in the oxidation reaction.Liming Zhai Bin Zhang Haojie Liang Huibin Wu Xinchun Yang Gen Luo Shichao Zhao Yong Qin 2021Science China Chemistry2021,64,7:2
9Impedance effect of manganite thin film-based photodetectors显示文摘We report on the photodetector structures based on perovskite manganite La0.67Ca0.33MnO3 thin films on tilted SrTiO3 (001) substrates. The photovoltaic effect has been observed in response to excitation by 308 nm ultraviolet laser pulse irradiation in duration of 20 ns at room temperature. The outputs ob- tained required no amplification. To reduce the deformation of the signal detected, a series of testing measurements were made to investigate the impedance effect. When the impedance at the oscilloscope end matched to the co-axis cable, the signal trace was almost triangular and symmetrical, with re- sponse time equal to the excitation laser. In addation, the response linearly depends on the irradiated area for low on-sample energy. The devices work well under unbiased conditions and so are simple to configure for practical applications.ZHAO Kun HE Meng Lü HuiBin 2008Chinese Science Bulletin2008,53,2:1

11Interfacial-Strain-Induced Structural and Polarization Evolutions in Epitaxial Multiferroic BiFeO_3(001) Thin Films显示文摘Varying the film thickness is a precise route to tune the interfacial strain to manipulate the properties of the multiferroic materials.Here,to explore the effects of the interfacial strain on the properties of the multiferroic BiFeO_3films,we investigated thickness-dependent structural and polarization evolutions of the BiFeO_3 films.The epitaxial growth with an atomic stacking sequence of BiO/TiO_2 at the interface was confirmed by scanning transmission electron microscopy.Combining X-ray diffraction experiments and first-principles calculations,a thickness-dependent structural evolution was observed from a fully strained tetragonality to a partially relaxed one without any structural phase transition or rotated twins.The tetragonality(c/a) of the BiFeO_3 films increases as the film thickness decreases,while the polarization is in contrast with this trend,and the size effect including the depolarization field plays a crucial role in this contradiction in thinner films.These findings offer an alternative strategy to manipulate structural and polarization properties by tuning the interfacial strain in epitaxial multiferroic thin films.郭海中 Ruiqiang Zhao Kui-juan Jin Lin Gu Dongdong Xiao Zhenzhong Yang Xiaolong Li Le Wang Xu He Junxing Gu Qian Wan Can Wang Huibin Lu Chen Ge Meng He Guozhen Yang 2015功能材料信息2015,12,3:1
12Evaluation of simulated reservoirs by using the oblique-incidence reflectivity difference technique显示文摘Dear Editors,The evaluation of the oil-gas resources’potential depends on the characterization of reservoirs.The geometry of the pore-crack structures and the compositions of the pore walls have influence on hydrocarbon production about capillarity and permeability[1].Besides,it has been known that the adsorption phenomenon in micro-structure plays a significant role in oil-gas reservoirs.Some techniques have been applied to characterize conventional and unconventional reservoirs,Jin Wang HongLei Zhan LiPing He Kun Zhao HuiBin Lü KuiJuan Jin GuoZhen Yang 2016Science China(Physics,Mechanics & Astronomy)2016,59,11:1

14Low-field positive and high-field negative magneto-resistances in multiphase Fe-oxide thin films at room temperature显示文摘Multiphase Fe-oxide thin films are fabricated on glass substrates by a facing-target sputtering tech- nique. X-ray diffraction and X-ray photoelectron spectroscopy reveal that Fe, Fe3BO4, γ -Fe2BO3B and FeO coexist in the films. High resolution transmission electron microscopy shows the well-defined colum- nar grain structure with the unoxidized Fe as the core and iron-oxide as the shell. The low-field positive and high-field negative magnetoresistances coexist in such a system at room temperature, which can be explained by considering a shell/core model. Nonlinear current-voltage curve and photovoltaic effect further confirm the tunneling-type conduction.ZHAO Kun XING Jie LIU YuZi ZHAO JianGao LU HuiBin 2007Chinese Science Bulletin2007,52,12:1

17A carbon nanoparticle-peptide fluorescent sensor custom-made for simple and sensitive detection of trypsin显示文摘Herein,we report a novel sensor to detect trypsin using a purpose-designed fluorescein-labelled peptide with negatively charged carbon nanoparticles(CNPs)modified by acid oxidation.The fluorescence of the fluorescein-labelled peptide was quenched by CNPs.The sensor reacted with trypsin to cleave the peptide,resulting in the release of the dye moiety and a substantial increase in fluorescence intensity,which was dose-and time-dependent,and trypsin could be quantified accordingly.Correspondingly,the biosensor has led to the development of a convenient and efficient fluorescent method to measure trypsin activity,with a detection limit of 0.7 mg/mL.The method allows rapid determination of trypsin activity in the normal and acute pancreatitis range,suitable for point-of-care testing.Furthermore,the applicability of the method has been demonstrated by detecting trypsin in spiked urine samples.Shanshan Hou Tingting Feng Na Zhao Jiaxin Zhang Huibin Wang Ning Liang Longshan Zhao 2020Journal of Pharmaceutical Analysis2020,10,5:0
18Structure and electrical characteristics of Nb-doped SrTiO3 substrates显示文摘The studies on structure and electrical characteristic of Nb-doped SrTiO3 (SNTO) substrates by XRD, Hall measurements, R-T and SEM, show that the SNTO substrates with the same Nb-doping concentration have different electrical properties be- cause of the nonuniformity of Nb-doping. The uni- formly doped high-quality substrates are extremely important for fabricating multilayer structure and de- vices. In addition, the experimental results also pro- vide us with SEM method to judge the uniformity of conducting material.HUANG Yanhong LUE Huibin GUO Haizhong LIU Lifeng HE Meng CHEN Zhenghao ZHOU Yueliang ZHAO Kun JIN Kuijuan YANG Guozen 2006Chinese Science Bulletin2006,51,16:0
19Epitranscriptomics and epiproteomics in cancer drug resistance:therapeutic implications显示文摘Drug resistance is a major hurdle in cancer treatment and a key cause of poor prognosis.Epitranscriptomics and epiproteomics are crucial in cell proliferation,migration,invasion,and epithelial–mesenchymal transition.In recent years,epitranscriptomic and epiproteomic modification has been investigated on their roles in overcoming drug resistance.In this review article,we summarized the recent progress in overcoming cancer drug resistance in three novel aspects:(i)mRNA modification,which includes alternative splicing,A-to-I modification and mRNA methylation;(ii)noncoding RNAs modification,which involves miRNAs,lncRNAs,and circRNAs;and(iii)posttranslational modification on molecules encompasses drug inactivation/efflux,drug target modifications,DNA damage repair,cell death resistance,EMT,and metastasis.In addition,we discussed the therapeutic implications of targeting some classical chemotherapeutic drugs such as cisplatin,5-fluorouridine,and gefitinib via these modifications.Taken together,this review highlights the importance of epitranscriptomic and epiproteomic modification in cancer drug resistance and provides new insights on potential therapeutic targets to reverse cancer drug resistance.Huibin Song Dongcheng Liu Shaowei Dong Leli Zeng Zhuoxun Wu Pan Zhao Litu Zhang Zhe-Sheng Chen Chang Zou 2020Signal Transduction and Targeted Therapy2020,5,1:0
20A Multi-Center Randomized Controlled Study UsingΔP_(CO2)/Ca-v_(O2)as the Target to Guide Early Tissue Hypoperfusion in Sepsis in Plateau Areas显示文摘Objective:To explore the value of using the venous-arterial carbon dioxide partial pressure difference and the arterial-venous oxygen content difference ratio(ΔP_(CO2)/Ca-v_(O2))as targets to guide early tissue hypoperfusion in sepsis in plateau areas.Methods:90 sepsis patients admitted to the Third People’s Hospital of Xining and Golmud People’s Hospital from June 2017 to December 2022 were selected as the research subjects,and they were divided into the Scv_(O2)(central venous oxygen saturation)group and theΔP_(CO2)/Ca-v_(O2)group,with 45 cases in each group.The two groups were treated with early shock resuscitation according to different protocols.The hemodynamic characteristics of the two groups of patients before and after resuscitation were observed,and the volume responsiveness was evaluated.The ROC(receiver operating characteristic)curve was used to analyze the significance ofΔP_(CO2)/Ca-v_(O2),Scv_(O2),lactate,lactate clearance,and urine output in evaluating patient prognosis and the correlation betweenΔP_(CO2)/Ca-v_(O2)and the above indicators was explored.Results:Compared with before resuscitation,after fluid resuscitation,the heart rate(HR),mean arterial pressure(MAP),central venous pressure(CVP),cardiac index(CI),lactate,lactate clearance rate,and urine output of the two groups of patients were significantly improved(P<0.05);in terms of therapeutic effect,the 28-day mortality rate,6-hour fluid balance,and lactic acid clearance of theΔP_(CO2)/Ca-v_(O2)group were better than the Scv_(O2)group.The ROC characteristic curve showed that theΔP_(CO2)/Ca-v_(O2)value can effectively predict the prognosis of patients(AUC=0.907,sensitivity was 97%,specificity was 72.4%,and critical value was 1.84).ΔP_(CO2)/Ca-v_(O2)significantly correlated with Scv_(O2),lactic acid,and lactic acid clearance rate.Conclusion:TheΔP_(CO2)/Ca-v_(O2)value can be used to guide fluid resuscitation in early hypoperfusion in sepsis in plateau areas,improve patients’hemodynamics,reduce lactate indicators,and increase urine output.ΔP_(CO2)/Ca-v_(O2)level>1.84 can effectively improve patient prognosis.Lianyu Zhang Fabin Zhang Huanying Bai Huibin Yun Zhao Zheng Shuncai Liu Shenghua A Zhongshan Shi Yuhai Hu 2024Journal of Clinical and Nursing Research2024,8,1:0
