| 1 | Fabrication of the Superhydrophobic Surface on Magnesium Alloy and Its Corrosion Resistance显示文摘The superhydrophobic surface was fabricated on the AZ31 alloy by the combination of the hydrothermal treatment method and post modification with stearic acid. The superhydrophobic surface showed a static water contact angle of 157.6°. The characteristics of the coatings were characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD) and Fourier transform infrared spectroscopy(FTIR). The corrosion resistance of the superhydrophobic coatings was investigated by potentiodynamic polarization test and electrochemical impedance spectroscopy(EIS). The results revealed that the superhydrophobic coatings, characterized by petal-like structure significantly improved the corrosion resistance of the AZ31 alloy. | Fen Zhang Changlei Zhang Liang Song Rongchang Zeng Shuoqi Li Hongzhi Cui | 2015 | Journal of Materials Science & Technology2015，31，11： | 17 |
| 2 | NbMoTiVSi_(x) refractory high entropy alloys strengthened by forming BCC phase and silicide eutectic structure显示文摘In order to improve mechanical properties of refractory high entropy alloys,silicide was introduced and NbMoTiVSi_(x)(x=0,0.1,0.2,0.3,and 0.4,molar ratio) refractory high entropy alloys are prepared by vacuum arc melting.Phase composition,micro structure evolution and mechanical properties were systematically studied.Results show that the silicide phase is formed in the alloys with addition of silicon,and the volume fraction of silicide increases from 0 to 8.3 % with increasing of silicon.Microstructure observation shows that the morphology of dendrite changes from columnar to near equiaxed,eutectic structure is formed at grain boundaries and composed of secondary BCC phase and silicide phase.The average length of the primary and second dendrites decreases with the increasing of silicon.Whereas,the ratio of eutectic structure increases from 0 to 19.8 % with the increment of silicon.The refinement of microstructure is caused by heterogeneous nucleation from the silicide.Compressive tests show that the yield and ultimate strength of the alloys increases from 1141.5 MPa to 2093.1 MPa and from 1700.1 MPa to 2374.7 MPa with increasing silicon content.The fracture strain decreases from 24.7 %-11.0 %.Fracture mechanism is changed from ductile fracture to ductile and brittle mixed fracture.The improvement of the strength is caused by grain bounda ry strengthening,which includes more boundaries around primary BCC phase and eutectic structure in grain boundary,both of them is resulted from the formation of silicide. | Qin Xu Dezhi Chen Chongyang Tan Xiaoqin Bi Qi Wang Hongzhi Cui Shuyan Zhang Ruirun Chen | 2021 | Journal of Materials Science & Technology2021，，1： | 9 |
| 3 | Self-Assembled Silane Film and Silver Nanoparticles Coating on Magnesium Alloys for Corrosion Resistance and Antibacterial Applications显示文摘Contamination resulting from microbial adhesion on magnesium alloys is very common in many applications.Self-assembly technology was employed to prepare an antibacterial composite coating by fixing silver nanoparticles(AgNPs)onto the surface of magnesium alloys.The AgNPs were immobilized on the surface of3-aminopropyltrimethoxysilane(APTMS)-modified magnesium alloy AZ31(APTMS/Mg)through electrostatic inter-attraction between partially protonated amino groups and negatively charged citrate-capped AgNPs,resulting in the AgNPs attached APTMS/Mg(AgNPs/APTMS/Mg)substrate.The prepared Ag colloid and functionalized AZ31 alloy were characterized by ultraviolet-visible(UV-vis)spectroscopy,Fourier transform infrared(FTIR)spectroscopy,scanning electron microscopy(SEM),and electrochemical methods.Finally,the bactericidal activity of AgNPs/APTMS/Mg substrate against Escherichia coli was assessed by the inhibition zone.The results demonstrated that Si-O-Si covalent bonds existed on the substrate with the formation of inorganic Si-O-Mg bonds.AgNPs were immobilized and well-dispersed,forming a uniform submonolayer on the silane film in two dimensions.The AgNPs/APTMS-pretreated AZ31 alloys exhibited better corrosion resistance and excellent antibacterial performance. | Rongchang ZENG Lijun LIU Shuoqi LI Yuhong ZOU Fen ZHANG Yanan YANG Hongzhi CUI En-hou HAN | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，6： | 8 |
| 4 | Addition Al and/or Ti Induced Modifi cations of Microstructures, Mechanical Properties, and Corrosion Properties in CoCrFeNi High-Entropy Alloy Coatings显示文摘The purpose of this work is to study the influences of Al and/or Ti addition on the microstructures, mechanical properties and corrosion properties of CoCrFeNi-(Al, Ti) high entropy alloy(HEA) coatings. Three coatings, AlCoCrFeNi(Ⅰ), CoCrFeNiTi_(0.5)(Ⅱ) and AlCoCrFeNiTi_(0.5)(Ⅲ), were fabricated by laser cladding successfully. The AlCoCrFeNi(Ⅰ) coating exhibited a simple body-centered cubic(BCC) solid-solution structure, whereas the CoCrFeNiTi_(0.5)(Ⅱ) alloy exhibited a face-centered cubic(FCC) solid-solution and a small amount of Laves phase. The BCC phases in AlCoCrFeNiTi _(0.5)(Ⅲ) coating were characterized as Fe–Cr rich disordered BCC phases(A2) and Al-Ni–Ti-rich ordered BCC phases(L2_1) separately. The AlCoCrFeNiTi_(0.5)(Ⅲ) coating with dual-phase BCC structure showed the optimal performance of both mechanical and corrosion properties, which was superior to BCC-based AlCoCrFeNi(Ⅰ) and FCC-based CoCrFeNiTi_(0.5)(Ⅱ) coatings. Nanoindentation tests and quantitative investigations on the strengthening mechanisms of AlCoCrFeNiTi_(0.5)(Ⅲ) coating were conducted, suggesting that the precipitation strengthening is the dominant strengthening mechanism. In short, the addition of moderate amount of Al and Ti in CoCrFeNi HEA shows potential for the development of a high strength and corrosion-resistant coating. | Guoliang Ma Yong Zhao Hongzhi Cui Xiaojie Song Mingliang Wang Kwangmin Lee Xiaohua Gao Qiang Song Canming Wang | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，8： | 4 |
| 5 | In vitro corrosion of Mg–1.21Li–1.12Ca–1Y alloy显示文摘The influence of the microstructure on mechanical properties and corrosion behavior of the Mg–1.21Li–1.12Ca–1Y alloy was investigated using OM, SEM, XRD, EPMA, EDS, tensile tests and corrosion measurements. The results demonstrated that the microstructure of the Mg–1.21Li–1.12Ca–1Y alloy was characterized by α-Mg substrate and intermetallic compounds Mg2 Ca and Mg24Y5. Most of the fine Mg2 Ca particles for the as-cast alloy were distributed along the grain boundaries, while for the as-extruded along the extrusion direction. The Mg24Y5 particles with a larger size than the Mg2 Ca particles were positioned inside the grains. The mechanical properties of Mg–1.21Li–1.12Ca–1Y alloy were improved by the grain refinement and dispersion strengthening. Corrosion pits initiated at the α-Mg matrix neighboring the Mg2 Ca particles and subsequently the alloy exhibited general corrosion and filiform corrosion as the corrosion product layer of Mg(OH)2and Mg CO3 became compact and thick. | Rongchang Zeng Weichen Qi Fen Zhang Hongzhi Cui Yufeng Zheng | 2014 | Progress in Natural Science:Materials International2014，24，5： | 4 |
| 6 | Photocatalytic H2 Evolution on TiO2 Assembled with Ti3C2 MXene and Metallic 1T-WS2 as Co-catalysts显示文摘The biggest challenging issue in photocatalysis is efficient separation of the photoinduced carriers and the aggregation of photoexcited electrons on photocatalyst’s surface.In this paper,we report that double metallic co-catalysts Ti3C2 MXene and metallic octahedral(1T)phase tungsten disulfide(WS2)act pathways transferring photoexcited electrons in assisting the photocatalytic H2 evolution.TiO2 nanosheets were in situ grown on highly conductive Ti3C2 MXenes and 1T-WS2 nanoparticles were then uniformly distributed on TiO2@Ti3C2 composite.Thus,a distinctive 1T-WS2@TiO2@Ti3C2 composite with double metallic co-catalysts was achieved,and the content of 1T phase reaches 73%.The photocatalytic H2 evolution performance of 1T-WS2@TiO2@Ti3C2 composite with an optimized 15 wt%WS2 ratio is nearly 50 times higher than that of TiO2 nanosheets because of conductive Ti3C2 MXene and 1T-WS2 resulting in the increase of electron transfer efficiency.Besides,the 1T-WS2 on the surface of TiO2@Ti3C2 composite enhances the Brunauer–Emmett–Teller surface area and boosts the density of active site. | Yujie Li Lei Ding Shujun Yin Zhangqian Liang Yanjun Xue Xinzhen Wang Hongzhi Cui Jian Tian | 2020 | Nano-Micro Letters2020，12，1： | 4 |
| 7 | Evaluating Common Land Model Energy Fluxes Using FLUXNET Data显示文摘Given the crucial role of land surface processes in global and regional climates, there is a pressing need to test and verify the performance of land surface models via comparisons to observations. In this study, the eddy covariance measurements from 20 FLUXNET sites spanning more than 100 site-years were utilized to evaluate the performance of the Common Land Model(Co LM) over different vegetation types in various climate zones. A decomposition method was employed to separate both the observed and simulated energy fluxes, i.e., the sensible heat flux, latent heat flux, net radiation, and ground heat flux, at three timescales ranging from stepwise(30 min) to monthly. A comparison between the simulations and observations indicated that Co LM produced satisfactory simulations of all four energy fluxes, although the different indexes did not exhibit consistent results among the different fluxes. A strong agreement between the simulations and observations was found for the seasonal cycles at the 20 sites, whereas Co LM underestimated the latent heat flux at the sites with distinct dry and wet seasons, which might be associated with its weakness in simulating soil water during the dry season. Co LM cannot explicitly simulate the midday depression of leaf gas exchange, which may explain why Co LM also has a maximum diurnal bias at noon in the summer. Of the eight selected vegetation types analyzed, Co LM performs best for evergreen broadleaf forests and worst for croplands and wetlands. | Xiangxiang ZHANG Yongjiu DAI Hongzhi CUI Robert E.DICKINSON Siguang ZHU Nan WEI Binyan YAN Hua YUAN Wei SHANGGUAN Lili WANG Wenting FU | 2017 | Advances in Atmospheric Sciences2017，34，9： | 4 |
| 8 | Synthesis of porous few-layer carbon nitride with excellent photocatalytic nitrogen fixation显示文摘The porous few-layer g-C_(3)N_(4)(PFL-g-C_(3)N_(4))is prepared by a simple molecular self-assembly method.Compared with pure g-C_(3)N_(4),the as-prepared PFL-g-C_(3)N_(4) is ultrathin,the surface is rich in pores,and the photocatalytic nitrogen fixation activity is greatly increased to 8.20 mM h^(-1) gCat^(-1).Few-layer and ultrathin nature of PFL-g-C_(3)N_(4) can provide a larger specific surface area,expose more active sites,and reduce the diffusion path of charges and protons from the inside to the surface.In addition,the porous structure can narrow the band gap,thereby increasing the light absorption range and enhancing the light absorption capability.Meanwhile,the presence of nitrogen vacancies causes PFL-g-C_(3)N_(4) to move to a more negative conductive band value.More importantly,the isotopic experiments using ^(15)N_(2) as nitrogen source confirm the ammonia production originating from N2 rather than the decomposition of g-C_(3)N_(4).Therefore,PFL-g-C_(3)N_(4) can greatly improve the efficiency of visible light photocatalytic nitrogen fixation. | Yanjun Xue Xiangkun Kong Yichen Guo Zhangqian Liang Hongzhi Cui Jian Tian | 2020 | Journal of Materiomics2020，6，1： | 3 |
| 9 | Enhanced strength and ductility in Ti46Al4Nb1Mo alloys via boron addition显示文摘To improve the strength and ductility of Ti Al alloys by second phase, Ti46 Al4 Nb1 Mo alloys doped with different B content(0.4%, 0.8%, 1.2%, 1.6% and 2.0%, atomic percent, hereafter in at.%, referred to as TNMx B) were prepared. Macro/microstructure evolution, mechanical properties and deformation mechanisms of the alloys were studied systematically. Results showed that the microstructure of TNM-0.4 B and TNM-0.8 B alloy remained columnar dendrites, and the secondary dendritic arms of columnar grains were more obvious. When the content of B is 1.2%, the columnar dendrites transformed to equiaxed grains, and theα2/γ lamellae colony size was further refined in TNM-1.6 B and TNM-2.0 B alloy. The morphologies and kinds of the borides were changed with increasing B content, XRD results showed that Ti B phase appeared with 1.6%B content, and both Ti B and Ti B2 phase formed in TNM-2.0 B alloy. There were straight and curved Ti B phases located around grain boundaries in TNM-0.4 B and TNM-0.8 B alloy, and when the content of B increased to 1.2%, the curved Ti B phases were reduced, while the tiny and straight Ti B phases increased. With further increasing B content to 1.6% and 2.0%, the tiny and straight Ti B phases were coarser. Compressive testing results showed that the mechanical properties of the TNM alloy were enhanced with increasing B content. The maximum strength and strain of TNM alloy were 2339 MPa and33.7% with 1.6% B addition. The compressive strength and strain were mainly enhanced via refinement of lamellar colony and formation of Ti B, and it is found that pile-up of dislocations and deformed twins promoted by Ti B are predominant in improving the mechanical properties of TNM alloys with higher strength and strain. | Yingmei Tan Ruirun Chen Hongze Fang Yangli Liu Hongzhi Cui Yanqing Su Jingjie Guo Hengzhi Fu | 2022 | Journal of Materials Science & Technology2022，，7： | 2 |
| 10 | Tailoring spin mixtures by ion-enhanced Maxwell magnetic coupling in colortunable organic electroluminescent devices显示文摘In this work,we show that the spin dynamics of excitons can be dramatically altered by Maxwell magnetic field coupling,together with an ion-enhanced,low-internal-splitting-energy organic semiconducting emitter.By employing a unique,alternating current(AC)-driven organic electroluminescent(OEL)device architecture that optimizes this magnetic field coupling,almost complete control over the singlet-to-triplet ratio(from fluorescent to phosphorescent emission in a single device)is realized.We attribute this spin population control to magnetically sensitive polaron–spin pair intersystem crossings(ISCs)that can be directly manipulated through external driving conditions.As an illustration of the utility of this approach to spin-tailoring,we demonstrate a simple hybrid(double-layer)fluorescence–phosphorescence(F–P)device using a polyfluorene-based emitter with a strong external Zeeman effect and ion-induced long carrier diffusion.Remarkable control over de-excitation pathways is achieved by controlling the device-driving frequency,resulting in complete emission blue–red color tunability.Picosecond photoluminescence(PL)spectroscopy directly confirms that this color control derives from the magnetic manipulation of the singlet-totriplet ratios.These results may pave the way to far more exotic organic devices with magnetic-field-coupled organic systems that are poised to usher in an era of dynamic spintronics at room temperature. | Junwei Xu Yue Cui Gregory M.Smith Peiyun Li Chaochao Dun Linqi Shao Yang Guo Hongzhi Wang Yonghua Chen David L.Carroll | 2018 | Light(Science & Applications)2018，7，1： | 2 |
| 11 | Precambrian Captured Zircon Ages in the Daheigou Formation, Xing’an Block显示文摘The Xing'an Block (XB) is located between the Erguna
Block (EB) and the Songnen Block (SB), which
topographically occupies the northeastern half of the Great
Xing'an Range (Liu et al., 2017). The XB was
traditionally considered to be composed of a Precambrian
metamorphic basement and post-Cambrian cover.
However, the recent geochronological studies show that
the so-called 'Precambrian metamorphic rocks^^ are much
younger in age and considered to be formed in the Early
Paleozoic, indicating no existence of the Precambrian
metamorphic basement. | SONG Wanbing CUI Fanghua YANG Hongzhi ZHANG Li WU Xinwei SHI Jianmin ZHANG Chao | 2019 | Acta Geologica Sinica(English Edition)2019，93，3： | 1 |

| 17 | Investigation on thermo-mechanical behavior of reinforced concrete energy pile with large cross-section in saturated sandy soil by model experiments显示文摘Energy piles are a new type of heat exchange systems with buried pipes in a pile foundation,which optimize a ground source heat pump system for the utilization of shallow geothermal energy.In this study,based on the principle of similarity,the thermo-mechanical behavior of the model energy pile with a large cross-section in saturated sandy soil was experimentally evaluated.The pre-cast model concrete pile with a diameter of 0.2 m and length of 1.5 m was buried in saturated sand in a steel box with dimensions of 2.5 m×2.5 m×2.0 m(length×width×height).The pile was heated using water in the polyethylene(PE)pipe,which was connected to a water cycle temperature controller.At a constant inlet water temperature of 55℃,three thermal cycles were carried out with the same heating and cooling periods and different water flow rates.The temperature distributions in the pile and soil,in addition to the pore pressure,soil pressure,and displacement of the pile,were monitored to clarify the thermo-mechanical behavior of the pile and soil.The heat transfer efficiency was analyzed based on the temperature difference and water flow rates.The measured strain at different locations in the pile under cyclic thermal loading revealed that the uneven strain that developed in a pile body should be considered for its long-term application.Furthermore,focus should be directed toward the long-term unrecoverable displacement of the energy pile due to the thermal plastic strain and thermal consolidation of the soil. | Xiaohua Bao Yubo Li Tangjie Feng Hongzhi Cui Xiangsheng Chen | 2020 | Underground Space2020，5，3： | 1 |

| 20 | The metallic 1T-WS_(2)as cocatalysts for promoting photocatalytic N_(2) fixation performance of Bi_(5)O_(7)Br nanosheets显示文摘Recently,widespread attention has been devoted to the typical layered BiOCl or BiOBr because of the suitable nanostructure and band structure.However,owing to the fast carrier recombination,the photocatalytic performance of BiOX materials is not so satisfactory.Loading 1T phase WS_(2)nanosheets(NSs)onto Bi_(5)O_(7)Br NSs can improve the photocatalytic N_(2)fixation activity.Among these,the obtained 1T-WS_(2)@Bi_(5)O_(7)Br composites with optimum 5%1T-WS_(2)NSs display a significantly improved photocatalytic N_(2)fixation rate(8.43 mmol L^(−1)h^(−1)g^(−1)),2.51 times higher than pure Bi_(5)O_(7)Br(3.36 mmol L^(−1)h^(−1)g^(−1)).And the outstanding stability of 1T-WS_(2)@Bi_(5)O_(7)Br-5 composites is also achieved.Exactly,the photoexcited electrons from Bi_(5)O_(7)Br NSs are quickly transferred to conductive 1T phase WS_(2)as electron acceptors,which can promote the separation of carriers.In addition,1T-WS_(2)NSs can provide abundant active sites on the basal and edge planes,which can promote the efficiency of photocatalytic N_(2)fixation.This work offers a novel solution to improve the photocatalytic performance of Bi_(5)O_(7)Br NSs. | Pengyuan Qiu Jianwei Wang Zhangqian Liang Yanjun Xue Yanli Zhou Xiaoli Zhang Hongzhi Cui Guiqing Cheng Jian Tian | 2021 | Chinese Chemical Letters2021，32，11： | 1 |
