| 1 | Superhydrophobic coatings for corrosion protection of magnesium alloys显示文摘Magnesium(Mg)alloys show great potential to be extensively applied in practice owing to their superior properties,while the poor corrosion resistance does undoubtedly restrict their applications.Superhydrophobic coatings with good repellency to corrosive solutions can significantly decrease the interaction between the corrosive species and the substrate,so that they are receiving a lot of attention to improve the corrosion resistance of Mg alloys.Various strategies have been introduced to develop a superhydrophobic coating on Mg alloys,which were reviewed to elucidate the current research status to provide a clue or thinking for beginning researchers.Further,the existing issues of superhydrophobic coating were discussed,especially for their real applications in practice,mainly owing to their poor mechanical stability.Based on the existing issues,the future study was discussed to improve the stability of hierarchical structures and entrapped air pockets,impart the superhydrophobic coating self-healing property to repair the damaged area during service,provide double protection by incorporation of corrosion inhibitors,or even introduce slippery liquid-infused porous surfaces with lubricant layer to provide better corrosion protection for Mg alloys. | Wenhui Yao Liang Wu Guangsheng Huang Bin Jiang Andrej Atrens Fusheng Pan | 2020 | Journal of Materials Science & Technology2020，52，17： | 15 |
| 2 | Clarifying the roles of grain boundary and grain orientation on the corrosion and discharge processes of α-Mg based Mg-Li alloys for primary Mg-air batteries显示文摘The corrosion behavior at open circuit potential(OCP)and discharge properties under applied anodic currents of twoα-Mg based Mg-Li alloys,i.e.,LAZ131 and LAZ531,with different microstructural features for primary Mg-air batteries are investigated.The results show that the grain boundaries contribute equally to the corrosion and discharge processes,which are attacked preferentially than the grain interiors and accelerate the dissolution processes ofα-Mg based Mg-Li alloys.The(10-10)/(11-20)orientated grains are attacked preferentially than the(0002)orientated grains on the corrosion and discharge process.The increased corrosion rate and improved discharge properties are attributed to the refinement of grain size,decreased content of(0002)orientated grains and increased content of(10-10)/(11-20)orientated grains.Of those,the LAZ531 alloy possesses high and steady discharge voltage at small discharge current density for long time,with the values of 1.4801 V at 2.5 mA cm^(-2)and 1.3742 V at 10 mA cm^(-2). | Huabao Yang Liang Wu Bin Jiang Wenjun Liu Jiangfeng Song Guangsheng Huang Dingfei Zhang Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，3： | 9 |
| 3 | Micro-arc oxidation of magnesium alloys:A review显示文摘Magnesium(Mg)and its alloys present great potential to be extensively applied in different applications.However,the relatively poor resistance to corrosion and wear significantly restricts their applications in practice.As one of strategies of surface treatment,micro-arc oxidation(MAO)process attracts a lot of attention,since it does not use neither expensive equipment,nor complicated manipulation.This review systematically discusses MAO mechanism and some typical models,which still need to be further developed to provide a better understanding and guide for future researchers.Subsequently,main influencing factors of MAO process are analyzed in detail.Further,some popular applications of MAO coatings are respectively reviewed,including biomedical application,decoration,thermal control,corrosion and wear resistance,and industrial applications in practice.The existing issues and future perspectives are finally discussed to further accelerate extensive applications of Mg alloys. | Wenhui Yao Liang Wu Jingfeng Wang Bin Jiang Dingfei Zhang Maria Serdechnova Tatsiana Shulha Carsten Blawert Mikhail L.Zheludkevich Fusheng Pan | 2022 | Journal of Materials Science & Technology2022，，23： | 8 |
| 4 | Doublely-doped Mg-Al-Ce-V_(2)O_(7)^(4-)LDH composite film on magnesium alloy AZ31 for anticorrosion显示文摘A doublely-doped layered double hydroxide(LDH)film was produced on an anodized magnesium alloy AZ31.The Ce-doped Mg-Al LDH film was prepared by in-situ hydrothermal treatment method,and the intercalation of vanadate was realized by ion-exchange reaction.The structure,morphology and composition of as-prepared LDH film were investigated by X-ray diffractometer,field-emission scanning electronic microscope and energy dispersive spectrometry.Results indicated that a uniform and compact LDH film was formed and the intercalation of Ce^(3+)and vanadate would change the crystal structure of LDHs.The results of the potentiodynamic polarization,electrochemical impedance spectra,hydrogen evolution and corrosion weight loss tests showed the Ce^(3+)and vanadate anions significantly improve the impedance of LDH film,and the active double-doped LDH film could effectively protect the magnesium substrate from corrosion. | Liang Wu Xingxing Ding Zhicheng Zheng Aitao Tang Gen Zhang Andrej Atrens Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，5： | 7 |
| 5 | Effects of deformation processes on morphology,microstructure and corrosion resistance of LDHs films on magnesium alloy AZ31显示文摘Highly oriented Mg-Al layered double hydroxide(LDHs)films were deposited on magnesium alloy AZ31 with different deformation processes by an easy in-situ growth method.The characteristics of the films were investigated by optical microscopy(OM),X-ray diffraction(XRD),scanning electron microscopy(SEM),and electrochemical,immersion and hydrogen evolution tests.The corrosion protection performance ranked the LDHs films as the increasing series:CS-LDHs(as-cast sample with LDHs) | Jing Chen Liang Wu Xingxing Ding Qiang Liu Xu Dai Jiangfeng Song Bin Jiang Andrej Atrens Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，5： | 6 |
| 6 | Variation of temporal and spatial patterns of NO_2 in Beijing using OMI and mobile DOAS显示文摘Control policies such as 'odd-and-even license plate rule' were implemented by the Chinese government to restrict traffic and suspend factory production in Beijing and neighboring cities during the Asia-Pacific Economic Cooperation summit. We use ozone monitoring instrument(OMI), mobile differential optical absorption spectroscopy(DOAS), and multi-axis differential optical absorption spectroscopy(MAX-DOAS) to measure the variation of the spatial and temporal patterns of NO2 column densities from October 24, 2014 to November 22, 2014. It is found that the NO2 column densities during the episode of control policies are significantly lower than those during other periods, and the emission flux of NO2 calculated by mobile DOAS is also lower than the results from other periods. Some daily low NO2 column densities occur with the northwest wind direction. We then compare the relationship between OMI and mobile DOAS NO2 column density observations, and the results of mobile DOAS are approximately 2.7 times larger than the OMI values. The largest discrepancy occurs in the northern part of Beijing city. In other parts, the two instruments have a better correlation coefficient(R2) of 0.61. The low NO2 column densities that occur during the episode of control policies are affected by the control policies as well as meteorological conditions. | Ang Li Jie Zhang Pinhua Xie Zhaokun Hu Jin Xu Fusheng Mou Fengcheng Wu Jianguo Liu Wenqing Liu | 2015 | Science China Chemistry2015，58，9： | 5 |
| 7 | Effects of Fe concentration on microstructure and corrosion of Mg-6Al-1Zn-xFe alloys for fracturing balls applications显示文摘Mg-6A1-1 Zn-xFe (x = 0,1,3,5 and 7 wt%) alloys were prepared by powder metallurgy and followed by hot extrusion. Majority of Fe element exists as insoluble particles in the alloys. The as-extruded alloys showed higher degradable rates but less stable mechanical properties than as-annealed alloys. Corrosion rate of all the alloys increased with increasing Fe concentration, reaching 2.4 mL cm^-2 h^-1.0.2% yield strength of all the alloys was higher than 150 MPa. In short, Mg-6A1-1 Zn-xFe alloys have an attractive combination of corrosion and mechanical properties, which holds a bright future for fracturing balls applications. | Cheng Zhang Liang Wu Guangsheng Huang Lin Chen Dabiao Xia Bin Jiang Andrej Atrens Fusheng Pan | 2019 | Journal of Materials Science & Technology2019，35，9： | 5 |
| 8 | Optimization of mechanical and damping properties of Mg-0.6Zr alloy by different extrusion processing显示文摘In this study,the optimization of mechanical and damping capacities of Mg-0.6 wt.%Zr alloys by controlling the recrystallized(DRXed)grain size under varying extrusion processing parameters including extrusion temperature T and strain rate was investigated.The relationship between the DRXed grain size and damping properties of the studied alloy was also discussed.The DRXed grain size of the as-extruded Mg-Zr alloys decreased as the extrusion temperature T decreased and the strain rateεincreased.As the DRXed grain size decreased,the strength and elongation of the as-extruded alloys exhibited improved performance through the grain refinement mechanism,while the damping properties deteriorated.The extrusion temperature of the Mg-Zr alloy had relatively greater effects on the mechanical and damping properties than the strain rate.The results of the present work indicate that alloys with appropriate mechanical and damping properties may be obtained from controlling the DRXed grain size by careful tailoring of the extrusion process parameters. | Jingfeng Wang Zhongshan Wu Shan Gao Ruopeng Lu Dezhao Qin Wenxiang Yang Fusheng Pan | 2015 | Journal of Magnesium and Alloys2015，3，1： | 4 |
| 9 | Construction of molecule-selective mixed matrix membranes with confined mass transfer structure显示文摘Extraordinary mass transfer phenomenon is usually found when the small molecules pass through a confined structure, whose effective size is commensurate with the mean free path of the molecules. Small changes in the confined mass transfer structure(including size, morphology and properties) will lead to significant fluctuations of the mass transfer coefficient. The mass transfer of the penetrant molecules in the dense membranes for pervaporation, gas separation and so on, is located in the scope of confined mass transfer. Incorporating nanofillers into polymer matrix to construct mixed matrix membranes(MMMs) is an effective approach to tune the confined mass transfer structure and enhance the performance of the widely used polymeric membranes. This review focuses on the construction and manipulation of the confined structure in the polymeric membranes via incorporating one-dimensional(1D), two-dimensional(2D) and three-dimensional(3D) fillers.The comparison of the MMMs for pervaporation is summarized, and the research prospective of the MMMs is provided. | Weidong Li Fusheng Pan Yimeng Song Meidi Wang Hongjian Wang Shalik Walker Hong Wu Zhongyi Jiang | 2017 | Chinese Journal of Chemical Engineering2017，25，11： | 3 |
| 10 | Development of metal-organic framework(MOF) decorated graphene oxide/Mg Al-layered double hydroxide coating via microstructural optimization for anti-corrosion micro-arc oxidation coatings of magnesium alloy显示文摘An efcient and simple in-situ growth strategy has been discovered for the preparation of highly reproducible and continuous symbiotic ZIF-8-based anticorrosion coating by using graphene oxide(GO)/Mg AlNO3layered double hydroxides(G/LDHs) buffer layer as a new type of connecting carrier based on micro-arc oxide(MAO) coating of AZ31 magnesium alloy. The components of ZIF-8 were adsorbed and bounded to the surface of the G/LDHs buffer layer-modified substrates to promote the nucleation of ZIF-8,thus growing a phase-pure, uniform, and good symbiosis ZIF-8 membrane. ZIF-8 particles with different growth times compensate for the grain boundary defects of the G/LDHs coating precursor buffer layer to different degrees. The prepared ZIF-8-based coating has excellent stability and corrosion resistance. The results demonstrate that the G/LDHs buffer layer provides a new channel for the MOF-modified MAO substrate of AZ31 magnesium alloy. It also proves that it is feasible to build high-performance anticorrosive coatings with MOF materials. | Yanning Chen Liang Wu Wenhui Yao Jiahao Wu Jianpeng Xiang Xiaowei Dai Tao Wu Yuan Yuan Jingfeng Wang Bin Jiang Fusheng Pan | 2022 | Journal of Materials Science & Technology2022，，35： | 3 |
| 11 | Application-oriented hydrolysis reaction system of solid-state hydrogen storage materials for high energy density target:A review显示文摘Hydrogen storage and delivery technology is still a bottleneck in the hydrogen industry chain.Among all kinds of hydrogen storage methods,light-weight solid-state hydrogen storage(LSHS)materials could become promising due to its intrinsic high hydrogen capacity.Hydrolysis reaction of LSHS materials occurs at moderate conditions,indicating the potential for portable applications.At present,most of review work focuses on the improvement of material performance,especially the catalysts design.This part is important,but the others,such as operation modes,are also vital to to make full use of material potential in the practical applications.Different operation modes of hydrolysis reaction have an impact on hydrogen capacity to various degrees.For example,hydrolysis in solution would decrease the hydrogen capacity of hydrogen generator to a low value due to the excessive water participating in the reaction.Therefore,application-oriented operation modes could become a key problem for hydrolysis reaction of LSHS materials.In this paper,the operation modes of hydrolysis reaction and their practical applications are mainly reviewed.The implements of each operation mode are discussed and compared in detail to determine the suitable one for practical applications with the requirement of high energy density.The current challenges and future directions are also discussed. | Jing Yao Zhen Wu Huan Wang Fusheng Yang Jianwei Ren Zaoxiao Zhang | 2022 | Journal of Energy Chemistry2022，31，11： | 3 |
| 12 | Enhanced Damping Capacities of Mg–Ce Alloy by the Special Microstructure with Parallel Second Phase显示文摘Microstructure evolution and damping capacities of Mg–Ce binary alloys with three different Ce contents(0.5, 1, or 2 wt%) have been systematically investigated in this work. Numerous fine parallel second phases in Mg–2Ce alloy are obtained, as well as a large number of dislocations around them, but few dislocations appear around the reticular second phase in the Mg–1Ce alloy. Among the three alloys, two internal friction peaks(P_1 and P_2) are detected at about 78 and 167?C in both the Mg–0.5Ce and Mg–1Ce alloys.In addition, the alloy with special parallel second phase structure exhibits excellent damping capacity in both strain amplitude and temperature-dependent regions. These results may be ascribed to the stress concentration and the formation of abundant parallel and uniform dislocation configurations in the ?-Mg matrix without the influence of crystal orientation. The obtained results may provide a novel idea to prepare high-damping magnesium alloys by tailoring their microstructure. | Zhongshan Wu Jingfeng Wang Haibo Wang She Ma Song Huang Shun Li Fusheng Pan | 2017 | Journal of Materials Science & Technology2017，33，9： | 3 |

| 14 | Nano-silica-decorated Poly(m-Phenylene Isophthalamide)Separator with Enhanced Mechanical and Electrolyte Wetting Properties for Lithium-Ion Batteries显示文摘Heat-resistant poly(m-phenylene isophthalamide)(PMIA)has attracted considerable attention as a novel separator for application in lithium-ion batteries(LIBs);however,its mechanical strength and electrolyte wettability are not ideal.Herein,a nano-silica-decorated poly(m-phenylene isophthalamide)(PMIA@SiO2)separator was fabricated with SiO2 nanoparticles uniformly attached to the pores and pore walls of the PMIA separator.The as-prepared PMIA@SiO2 separator has good mechanical strength(a 16%improvement compared with pristine PMIA)and wettability toward the electrolyte(the contact angle decreases from 34.0°to 23.1°).The PMIA@SiO2 separator also had a high ionic conductivity(0.75 mS/cm)and low interfacial electric resistance(75Ω).The assembled LiCoO2/PMIA@Si O2-liquid electrolyte/Li cell displays good cycle performance with a capacity retention of 88.1%after 50 cycles.Furthermore,the cycling performance and rate capacity rarely changed after high-temperature treatment.Therefore,the nano-silica-decorated PMIA separator is a potential candidate for application in LIBs with high safety. | Jianjie Wang Biao Yuan Fusheng Pan Lina Qiao Jun Guo Cuijia Duan Wei Wu Zan Chen anlei Su | 2020 | Transactions of Tianjin University2020，26，4： | 2 |
| 15 | Cavernous Weathering in Aeolian Sandstones: An Example from the Yongningshan Hill of the Loess Plateau, Northwest China显示文摘Cavernous weathering is commonly found on sandstone slopes in different environments. Either a single dominant process or polygenetic agents require to be invoked in order to interpret the development. The Yongningshan hill of the central Loess Plateau is representative of cliff dwellings in Northwest China, which is characterized by well-developed cavernous weathering features and provides a good opportunity for the better understanding of sandstone weathering in the Loess Plateau. Multiple methods, including field survey, in-situ rock strength measurement, along with experiments on samples for microscopic observation, element composition and salt chemistry, were employed to investigate the controlling factors of cavernous weathering. The results show that cavern development is different on the four slopes with the western slope hosting massive honeycombs, tafoni and hardened surfaces. The porous and permeable aeolian sandstones are fundamental, because they provide space and pathways for the transportation of water and salt, honeycombs dominantly aligning within the lamination of cross-beds. The environmental factors such as the seasonal wetting and drying cycle, aeolian salt, moisture and water vapor are key factors for the development of cavernous weathering forms. The northern and northwestern wind-blown dust storms have brought abundant salts, the lengthier dry periods of the wetting and drying cycle being beneficial for salt accumulation within caverns, favoring salt weathering. | CHEN Liuqin Piotr MIGOŃ GUO Fusheng PAN Zhixin WU Hao | 2022 | Acta Geologica Sinica(English Edition)2022，96，5： | 2 |
| 16 | Co-transplantation of Schwann cells and bone marrow stromal cells versus single cell transplantation on repairing hemisected spinal cord injury of rats显示文摘BACKGROUND: Bone marrow stromal cells (BMSCs) or Schwann cells (SCs) transplantation alone can treat spinal cord injury. However, the transplantation either cell-type alone has disadvantages. The co-transplantation of both cells may benefit structural reconstruction and functional recovery of spinal nerves. OBJECTIVE: To verify spinal cord repair and related mechanisms after co-transplantation of BMSCs and SCs in a rat model of hemisected spinal cord injury. DESIGN, TIME AND SETTING: A randomized, controlled, animal experiment was performed at the Department of Histology and Embryology, Mudanjiang Medical College from January 2008 to May 2009. MATERIALS: Rabbit anti-S-100, glial fibrillary acidic protein, neuron specific enolase and neurofilament-200 monoclonal antibodies were purchased from Sigma, USA. METHODS: A total of 100 Wistar rats were used in a model of hemisected spinal cord injury. The rats were randomly assigned to vehicle control, SCs transplantation, BMSCs transplantation, and co-transplantation groups; 25 rats per group. At 1 week after modeling, SCs or BMSCs cultured in vitro were labeled and injected separately into the hemisected spinal segment of SCs and BMSCs transplantation groups through three injection points [5 μL (1 × 107 cells/mL)] cell suspension in each point). In addition, a 15 μL 1 × 107 cells/mL SCs suspension and a 15 μL 1 × 107 cells/mL BMSC suspension were injected into co-transplantation group by the above method. MAIN OUTCOME MEASURES: The Basso-Beattie-Bresnahan (BBB) locomotor rating scale and somatosensory evoked potential (SEP) tests were used to assess the functional recovery of rat hind limbs following operation. Structural repair of injured nerve tissue was observed by light microscopy, electron microscopy, immunohistochemistry, and magnetic resonance imaging (MRI). In vivo differentiation, survival and migration of BMSCs were evaluated by immunofluorescence. RESULTS: BBB scores were significantly greater in all three transplantation groups compared with vehicle control group 8 weeks after transplantation. In particular, the co-transplantation group displayed the highest scores among the groups (P < 0.05). Moreover, recovery of SEP latency and amplitude was observed in all the transplantation groups, particularly after 8 weeks. Again, the co-transplantation group exhibited the greatest improvement (P < 0.05). In the co-transplantation group, imaging showed a smooth surface and intact inner structure at the injury site, with no scar formation, and a large number of orderly cells at the injured site. Axonal regeneration, new myelination, and a large amount of cell division were detected in the co-transplantation group by electron microscopy. Neuron specific enolase (NSE)- and glial fibrillary acidic protein (GFAP)-positive cells were observed in the spinal cord sections 1 week following co-transplantation by immunofluorescence staining. CONCLUSION: Co-transplantation of SCs and BMSCs effectively promoted functional recovery of injured spinal cord in rats compared with SCs or BMSCs transplantation alone. This repair effect is probably achieved because of neuronal-like cells derived from BMSCs to supplement dead neurons in vivo. | Jifei Zhang Geng Wu Fusheng Zhao Xiudong Jin | 2010 | Neural Regeneration Research2010，5，11： | 2 |
| 17 | Replanting of broadleaved trees alters internal nutrient cycles of native and exotic pines in subtropical plantations of China显示文摘Background:The replanting of broadleaved trees in pure coniferous plantations is widely implemented,as mixed plantations are generally more stable and functional.However,the effect of interspecific interactions between broadleaved and coniferous trees on internal nutrient cycles of conifers remains unclear.Methods:We selected pure coniferous plantations of a native(Pinus massoniana)and an exotic(P.elliottii)pine species and their corresponding mixed plantations with broadleaved trees(Schima superba)in subtropical China,and measured the nitrogen(N)and phosphorus(P)contents in the rhizosphere soils,fine roots,twigs,needles and needle litter of pines.We calculated the root capture,needle resorption and translocation of N and P by pines to determine the mobility of nutrients in trees.Results:Although the N and P in the rhizosphere soils increased due to the replanting of broadleaved trees,the N and P contents in the aboveground tissues of the two pine species did not increase in mixed plantations.Mixed planting had a negative effect on the N and P capture of native pine and a positive effect on that of exotic pine.The N and P resorption efficiencies increased in native pine but were unchanged in exotic pine after the replanting of S.superba.Native pine preferentially employed an aboveground nutrient resorption strategy,whereas exotic pine tended to adopt a belowground nutrient capture strategy after replanting.Translocation of N and P in trees was detected,which reflected the trade-offs between root nutrient capture and needle nutrient resorption.Conclusions:The effect of mixed planting varied between the species of native and exotic pines,and the internal nutrient cycles of both pine species might be dominated by interspecific interaction effects on nutrients rather than soil nutrients.Our study highlights the importance of selecting suitable broadleaved species for replanting in coniferous plantations. | Yong Lin Chengkang Xia Gaoyang Wu Fangchao Wang Shengnan Wang Yuanqiu Liu Fusheng Chen | 2022 | Forest Ecosystems2022，9，5： | 2 |
| 18 | In-situ LDHs growth on PEO coatings on AZ31 magnesium alloy for active protection:Roles of PEO composition and conversion solution显示文摘In this work,plasma electrolytic oxidation(PEO)coatings were produced on magnesium alloy AZ31 in aluminate,silicate and phosphate-based electrolytes,and followed by hydrothermal treatments in order to synthesis layered double hydroxides(LDHs)based nanocontainers.LDHs synthesis was done in three different growth solutions(deionized water,sodium nitrate and aluminum nitrate containing solution).In frame of this work it was shown,that it was difficult to form LDHs on Si-based PEO coating,due to more stable silicate phases in comparison with aluminate and phosphate phases in respective PEO coatings.The obtained hybrid LDH/PEO coatings were characterized using SEM,EDS and GDOES,and then the corrosion protection was further investigated by EIS.Based on the obtained results,it was confirmed that,the hydrothermal treatments in Al^(3+)containing solution played an important role on overall corrosion resistance for phosphate and silicate-based PEO coatings,but not for Al-based PEO coatings. | Gen Zhang Liang Wu Maria Serdechnova Aitao Tang Cheng Wang Carsten Blawert Fusheng Pan Mikhail L.Zheludkevich | 2023 | Journal of Magnesium and Alloys2023，11，7： | 1 |
