3Fe-based metallic glass:An efficient and energy-saving electrode material for electrocatalytic degradation of water contaminants显示文摘Excessive consumption of electrical energy has hampered the widespread application of electrochemical technology for degradation of various contaminants. In this paper, a Fe-based metallic glass(MG) was demonstrated as a new type of electrocatalyst to effectively and economically degrade an azo dye. In comparison to other typical electrodes, Fe-based MG electrodes exhibit a minimized degradation time, and the specific energy is 4-6 orders of magnitude lower than that of dimensionally stable anode(DSA), metal-like boron-doped diamond(BDD) and other electrodes. As sacrificial electrode materials, Fe-based MGs have less specific electrode mass consumption than iron electrodes. The use of Fe-based MGs will promote the practical application of electrochemical technology and the use of MGs as functional materials.Xindong Qin Zhengkun Li Zhengwang Zhu Huameng Fu Hong Li Aimin Wang Hongwei Zhang Haifeng Zhang 2018Journal of Materials Science & Technology2018,34,12:3
4Analysis of Vitamin P Content and Inheritance Models in Eggplant显示文摘The eggplant(Solanum melongena L.)is rich in vitamin P(also known as rutin),which is beneficial for humans.In this study,the vitamin P contents of 53 eggplant lines were measured via UV spectrophotometry.The results showed that the vitamin P content differed significantly among the eggplant lines and the actual contents of vitamin P in fresh fruit pulp and fresh peel were 0.18–0.82mg·g^−1 and 0.42–2.32mg·g^−1,respectively.Furthermore,themixed major gene and polygene inheritance modelmethod was used for the inheritance analysis of the vitamin P content in F2 populations of three hybridization combinations.Inheritance analysis demonstrated that the vitamin P content of these eggplant lines was a quantitative trait.One or two major genes were the contributor,and the genetic effect was an additive-dominance effect.The high vitamin P content trait was regulated by the main gene and followed an additive effect.The heritability of the major genes controlling the high vitamin P content was low,while the heritability of the major gene that controls the low vitamin P content trait was high.These results provide a theoretical basis for the breeding of eggplants with high vitamin P content.Riyue Dong Bingwei Yu Shuangshuang Yan Zhengkun Qiu Jianjun Lei Changming Chen Ye Li Bihao Cao 2020Horticultural Plant Journal2020,6,4:3
5Treatment of constipation-predominant irritable bowel syndrome by focusing on the liver in terms of Traditional Chinese Medicine:a meta-analysis显示文摘OBJECTIVE:To assess the efficacy of Traditional Chinese Medicine(TCM)on constipation-predominant irritable bowel syndrome by focusing on the liver.METHODS:Databases(domestic and foreign)were searched with the key words'irritable bowel syndrome','constipation',and'Chinese medicine';the relevant articles were retrieved and evaluated.Cure rate,'remarkable efficacy',recurrence rate and the incidence of adverse reactions were the outcome indicators.Review Manager ver 5.1 was used for this meta-analysis,and funnel plots used to detect publication bias.RESULTS:Nineteen randomized controlled trials were included and 1510 patients involved.The treatment guided byTCM based on the liver was superior to Western Medicine[odds ratio(OR)=2.46,95%confidence interval(CI)1.80,3.35)],cure rate[OR=2.61,95%CI(1.93,3.52)],remarkable efficacy[OR=2.68,95%CI(1.82,3.95)],recurrence rate[OR=0.19,95%CI(0.12,0.29)]and the incidence of adverse reactions[OR=0.24,95%CI(0.09,0.65)].However,funnel plots showed publication bias.CONCLUSION:Compared with Western Medicine,the treatment of IBS-C based on the liver is significantly better but the results must be treated with caution because publication bias was recorded.Qianwen Li Fengbin Liu Zhengkun Hou Di Luo 2013Journal of Traditional Chinese Medicine2013,33,5:3
6Highly efficient and stable CuZr-based metallic glassy catalysts for azo dye degradation显示文摘Metallic glasses with the unique disordered atomic structure and metastable nature have been recently applied to degrade the azo dyes and other organic pollutants based on their superior catalytic performance.In this work,the functional properties of six Cu Zr-based metallic glassy ribbons with the different nominal components in degrading Acid OrangeⅡ(AOⅡ)azo dyes were investigated.The Cu47.5Zr46Al6.5 metallic glassy ribbons could exhibit the more advanced catalytic performance for degradation process,which could completely degrade azo dye aqueous solution within 30 min.Additionally,the Cu47.5Zr46Al6.5 metallic glassy ribbons also showed the excellent cyclic stability along with approximately 97.68%degradation efficiency after 10 cycles.These excellent catalytic performance and stability are closely related to the synergistic effect of exposed copper nanoparticles and produced copper oxides in the reaction,which contributes to accelerate the generation of more hydroxyl radicals(·OH)to react with dye molecules.Our findings can be able to develop a novel potential metallic glassy material for the functional application of wastewater treatment.Bowen Zhao Zhengwang Zhu Xin Dong Qin Zhengkun Li Haifeng Zhang 2020Journal of Materials Science & Technology2020,42,11:3
7Correlation Between Dynamic Compressive Strength and Fracture Behaviors of Bulk Metallic Glasses显示文摘The mechanical behaviors of Zr43.5Cu43.5Ni4Al8Nb1,Zr55.4Cu31.6Ni4Al8Nb1,Ti32.8Zr30.2Ni5.3Cu9Be22.7(at.%)metallic glass at different strain rates were studied.For all the present alloys,the dispersion over 700 MPa was observed on the strength in the repeated dynamic compressions,which was much stronger than that of the quasi-static compressive strength.Such the dispersion of the dynamic compressive strength was well correlated with the corresponding fracture behaviors.The area of fracture surface was calculated and also showed a strong dispersion for all the fractured specimens tested at the strain rate of 500 s^-1 and 1000 s^-1.All the specimens showed a linear relationship between the square of dynamic compressive strength and the area of fracture surface in the dynamic compression tests.This phenomenon was mainly thought to be related to the difference of mean initial free volume concentration of different samples,stress concentration caused by the split Hopkinson pressure bar experimental setup and high sensitivity of defects under dynamic deformation.These findings were beneficial to deeply understand the effect of strain rate on the mechanical properties of the metallic glass.Wenqing Li Zhengwang Zhu Guojie Li Long Zhang Zhengkun Li Huameng Fu Hongwei Zhang Hong Li Aimin Wang Haifeng Zhang 2020Acta Metallurgica Sinica(English Letters)2020,33,10:2
8Co_(78)Si_(8)B_(14)metallic glass:A highly efficient and ultra-sustainable Fenton-like catalyst in degrading wastewater under universal pH conditions显示文摘Overcoming the pH limitation and increasing the catalyst reusability remain pressing demands for metal-lic glass(MG)in wastewater remediation.Herein,Co_(78)Si_(8)B_(14)MG ribbons are used to degrade dye wastew-ater by activating hydrogen peroxide(H_(2)O_(2))as Fenton-like catalysts.The Co-based MG catalysts exhibit high degradation efficiency under both acidic and alkaline conditions,and the kinetic reaction rate at pH 10(0.176 min^(−1)) and pH 4(0.089 min^(−1)) is 5.9 and 1.2 times higher than that of the extensively studied Fe-based MG catalysts,respectively.Impressively,the Co-based MG catalysts can be reused up to 20-60 times at universal pH conditions,demonstrating fairly good reusability.The newly discovered Co-based MG catalysts do not follow the classical Fenton reactions with H_(2)O^(2) the way Fe-based MGs do.In an acid environment,hydroxyl radicals play a dominant role in the degradation,while in an alkaline environ-ment,the effect of hydroxyl radicals is weakened,and Co^(3+) ions exert a relatively major function on the degradation.The excellent performance in catalytic activity and reusability at universal pH conditions of the Co-based MGs will inspire the development of MGs in wastewater treatment.Xindong Qin Jiliang Xu Zhengwang Zhu Zhengkun Li Dawei Fang Huameng Fu Shiming Zhang Haifeng Zhang 2022Journal of Materials Science & Technology2022,,18:2
9Mechanism and kinetics of treatment of acid orange II by aged Fe-Si-B metallic glass powders显示文摘The mechanism and kinetics of acid orange II(AOII) treated by aged gas-atomized Fe-Si-B metallic glass(MG) powders were investigated in this study. The decolorization reaction is shown to obey the pseudofirst-order kinetic model, and the treatment processes could be divided into two stages: a slow step followed by a rapid one. This observation is in accordance with the following results, the azo dye is simply adsorbed onto the Fe-based MG powders in the initial stage, because the oxide layer coated on the powder surface depresses the degradation reaction by covering the activity sites, and then the degradation occurs with the desquamation of the powders. The AOII could be degraded with a rapid reaction rate when the Fe-based MG powders are applied to the treatment process again, because of the consumption of the oxide layer and the unchanged core of the Fe-based MGs. These findings will promote the practical application of MGs in degrading azo dyes.Xindong Qin Zhengkun Li Zhengwang Zhu Huameng Fu Hong Li Aimin Wang Hongwei Zhang Haifeng Zhang 2017Journal of Materials Science & Technology2017,33,10:2

11Corrosion mechanisms of Zr-based bulk metallic glass in NaF and NaCl solutions显示文摘So far,some investigations related to the corrosion mechanism of Zr-based metallic glasses in solutions containing Cl-have been developed.However,few attentions have been paid to the situation in F--containing solution.This paper describes the corrosion behaviours of Zr52Al10Ni6Cu32 bulk metallic glass(BMG)in Na F and Na Cl aqueous solutions.The corrosion mechanism of Zr-based BMG in F–containing solution was proposed for the first time.It was found that in Na Cl solutions,Zr-based BMG samples underwent typical pitting corrosion.Selective dissolution of Zr,Al and enrichment of Cu were observed in corrosion pits.However,corrosion occurred in the form of general breakdown of passive film in Na F solutions.Such difference is interpreted in terms of the binding ability of anions to surrounding molecules,i.e.,Cl-with loose surrounding water passes through the passive film to cause pitting;F-with a tight surrounding molecules layer absorbs on passive film then coordinates with cations from matrix.Zhangweijia Qiu Zhengkun Li Huameng Fu Hongwei Zhang Zhengwang Zhu Aimin Wang Hong Li Long Zhang Haifeng Zhang 2020Journal of Materials Science & Technology2020,42,11:1

15High-temperature Mechanical Properties and Dynamic Recrystallization Mechanism of in situ Silicide-reinforced MoNbTaTiVSi Refractory High-entropy Alloy Composite显示文摘The hypoeutectic composite material composed of BCC phase and in situ precipitated Ti_(5)Si_(3) was prepared by adding Si into MoNbTaTiV high-entropy alloy.The obvious oriented in situ Ti_(5)Si_(3) phase formed eutectic phase with BCC phase in the inter-dendritic area,which leads to excellent properties of the composite.The alloy exhibits ultra-high yield stress of 718 MPa at 1200℃ and obvious compression plasticity.After reaching the maximum strength,dynamic recovery(DRV)and dynamic recrystallization(DRX)caused soften phenomena.The DRX mechanism of the dual-phase eutectic structure is analyzed by electron backscatter diffraction.The DRX of the BCC phase conforms to the discontinuous DRX and continuous DRX mechanisms,while the Ti_(5)Si_(3) phase has a geometric DRX mechanism in addition to the above two mechanisms.The high performance of this composite has enough potential high-temperature applications such as nuclear and aero engine.Shaofan Ge Shifeng Lin Huameng Fu Long Zhang Tieqiang Geng Zhengwang Zhu Zhengkun Li Hong Li Aimin Wang Hongwei Zhang Haifeng Zhang 2022Acta Metallurgica Sinica(English Letters)2022,35,10:1
16Interface engineering of Fe-Co_(3)N/CoP composite with N-doped C by using soybean:Fabrication of efficient electrocatalysts for oxygen evolution reaction显示文摘Soybean can serve as an efficient carbon and nitrogen source for in-situ fabrication of efficient composite electrocatalysts with conductive nitrogen-doped carbon(N-C)material.In this study,the iron-doped cobalt nitride/phosphide(Fe-Co_(3)N/CoP)nanosheet was composited with a conductive N-C material by using soybean as C and N source,as well as NH3 as additional nitrogen source.During the nitridation process of Fe-Co_(3)N,N-C bond was formed as a newly generated Co(Fe)-N-C active sites.Therefore,it fabricates a good microscopic contact interface between the catalyst and carbon material for charge transfer.Besides,the introduction of Fe-CoP by partially phosphating Fe-Co_(3)N further improved the OER activity due to the high catalytic activity of Co sites with high valence state.As a result,the obtained electrocatalyst exhibited overpotentials as low as 285 and 390 mV for supporting 10 and 100 mA/cm��2 current densities.This work indicates that the design of materials with good interfaces could be an effective approach for the preparation of electrocatalysts for water electrolysis.Longqing Gao Xiumin Li Chao Tang Tianshuo Xie Zhengkun Xie Haimei Li Guoqing Guan Jie Liu Keyong Tang 2023Carbon Resources Conversion2023,6,2:1
17Preparation,Performance and Slag Resistant Mechanism of Low Thermal Conductivity Microporous Corundum显示文摘The microporous corundum material was prepared using alumina micro-powder as the main raw material,alumina sol and starch as binders by a wet process,achieving the bulk density of 3. 05 g·cm^(-3),the apparent porosity of 9. 1%,the closed porosity of 12. 3%,the median pore diameter of 0. 43 μm,and the thermal conductivity of 6. 5 W·m^(-1)·K^(-1)at 800 ℃ which is41. 6% lower than that of common corundum. The slag resistance of the microporous corundum material was studied by immersion and compared with that of the common corundum aggregate, and the slag resistant mechanism of microporous corundum material was revealed. The results show that the slag resistance of the microporous corundum material is superior to that of the common corundum aggregate,the SEM and EDX show that on the reaction interface between microporous corundum and molten slag,a continuous isolation layer with a large quantity of CA_2 and CA_6columnar crystals is formed; while the common corundum aggregate reacts with the molten slag interface to form a discontinuous isolation layer of columnar crystals,through which a lot of molten slag corrodes or permeates into the aggregate. The mechanism is mainly that the microporous structure is more advantageous to nucleation and growth of CA_2 and CA_6 columnar crystals; in the reaction with the aggregate,the molten slag gets saturated and the critical solution thickness of the microporous corundum and the common corundum is 0. 16 μm and 0. 34 μm,respectively,this is caused by the smaller microporous corundum aggregate pores; and the smaller pores also increase the second phase ripening rate of microporous corundum,which is 9. 7 times of that of the common corundum.FU Lyuping HUANG Ao GU Huazhi ZHANG Meijie LI Zhengkun ZHAO Yi 2015China's Refractories2015,24,4:0
18Green strategy of scaleably synthesizing copper nanocomposites with remarkable catalytic activity for wastewater treatment显示文摘The functional copper nanocomposites(Cu NCs)have received increasing attention in the environmental catalysis application for wastewater treatment due to their superior catalytic activity and reactivity.However,overcoming the pH limitations towards the neutral and alkaline wastewater remains a tricky challenge.In this work,we demonstrate a green strategy to synthesize Cu NCs with coexistence of active Cu,Cu_(2)O and ZrO_(2)by self-propagating combustion of metallic glassy ribbons,which exhibit the extremely superior catalytic performance for degradation reaction,providing full conversion of organic dyes completely to the environmental friendly small species(efficiency>99%)under acidic,neutral and alkaline conditions.Compared with all other catalysts developed thus far,the novel Cu NCs catalysts with more active sites present much enhanced catalytic capability of degradation efficiency without the use of any chemical reagents for neutral and alkaline organic dye solutions.The possible decomposition pathways of organic dyes for different p H systems were systematically investigated.More importantly,the two kinds of catalytic mechanism related to high reactivity of nanoscale Cu/Cu_(2)O and strong oxidizing capability of activated·OH/·O_(2)^(-)radicals can also be successfully confirmed under different pH conditions.The green synthetic approach can be extended to design the various M-based nanocomposites(M=Fe,Co,Ni,Ag,Pd)as efficient catalysts for the functional applications of many chemical reactions.Bowen Zhao Hailong Li Zhengkun Li Shaofan Ge Xindong Qin Shiming Zhang Aimin Wang Haifeng Zhang Zhengwang Zhu 2021Journal of Materials Science & Technology2021,,36:0
19Efficient synthesis of cyclic carbonates under atmospheric CO_(2) by DMAP-based ionic liquids: the difference of inert hydrogen atom and active hydrogen atom in cation显示文摘The coupling reaction of carbon dioxide(CO_(2)) and epoxides is one of the most efficient pathways to achieve the carbon balance.However,to accomplish it under the mild conditions,especially under the atmospheric pressure,is still a perplexing problem.Three novel ionic liquids(ILs),[DMAPBrPC][TMGH],[DMAPBrPC][DBUH],and[DMAPBrPC][BTMA],are designed and synthesized.All of them display the excellent catalytic activity for the title reaction achieving the yield over 96.6% under the atmospheric CO_(2) pressure at 60℃.Interestingly,[DMAPBrPC][BTMA]with the inert hydrogen atom in cation exhibits the superior catalytic activity as compared to other two ILs with the protic hydrogen atom in cation along with the same anion.The active hydrogen atom in[DMAPBrPC][TMGH]and[DMAPBrPC][DBUH]would impede the–COO^(-)group to absorb CO 2,which is an unfavorable item for the reaction.Moreover,the strong hydrogen bond in[DMAPBrPC][TMGH]and[DMAPBrPC][DBUH]would lessen the nucleophilic ability of Br^(-) anion resulting in the inferior catalytic performance,which is further confirmed by the density functional theory(DFT)calculations.The cation without the active hydrogen atom could also be employed to design the ILs with the excellent catalytic feature when it is combined with the suitable anion.Zhengkun Zhang Jinya Li Guanyao Yu Chao Zeng Menglong Wang Susu Huang Li Wang Jinglai Zhang 2023Green Chemical Engineering2023,4,3:0
20Simultaneous enhancement of strength and ductility of body-centered cubic TiZrNb multi-principal element alloys via boron-doping显示文摘Body-centered cubic(BCC)multi-principal element alloys(MPEAs)have intrinsic high strength but poor ductility,which greatly limits their potential applications.Here we present the boron-doping strategy to enhance the strength and ductility of TiZrNb MPEAs simultaneously.The yield strength and ductility of the TiZrNb MPEA with boron addition of 500 ppm are increased by 19.0%and 48.7%compared to the boron-free TiZrNb MPEA,respectively.Boron-doping induced high efficiency in grain refinement from~96.0μm to~16.2μm is the main factor for strengthening.Dislocation dominated deformation mechanism involving cross slip and dislocation pining in the TiZrNb containing 500 ppm boron serves to enhance the strain-hardening capacity,resultant the enhancement of ductility from 7.8%to 11.6%.While the planar slip of dislocations is the dominated deformation mechanism for the boron-free TiZrNb.Jingyu Pang Hongwei Zhang Long Zhang Zhengwang Zhu Huameng Fu Hong Li Aimin Wang Zhengkun Li Haifeng Zhang 2021Journal of Materials Science & Technology2021,,19:0
