1Direct reduction of hematite powders in a fluidized bed reactor显示文摘Ultrafine hematite powder was reduced to produce ultrafine iron powder in a 50%Ar-50%H_2 atmosphere at 450-550℃ in a fluidized bed reactor.The ultrafine hematite powder shows the typical agglomerating fluidization behavior with large agglomerates fluidized at the bottom of the bed and small agglomerates fluidized at the upper part of the bed.It was found that defluidization occurred even at the low temperature of 450℃ with low metallization rate.Defluidization was attributed mainly to the sintering of the newly formed iron particles.Granuation was employed to improve the fluidization quality and to tackle the defluidization problem,where granules fluidized like a Geldart's group A powder.Granulation was found to effectively reduce defluidization during reduction,without however sacrificing reduction speed.The asreduced iron powders from both the ultrafine and the granulated hematite exhibited excellent sintering activity,that is,fast sintering at temperature of as low as^580σ_(RR)~2),which is much superior as compared to that of nano/ultrafine iron powders made by other processes.Qingshan Zhu Rongfang Wua Hongzhong Li 2013Particuology2013,11,3:8
2Assembling of a novel 3D Ag(Ⅰ)-MOFs with mixed ligands tactics:Syntheses, crystal structure and catalytic degradation of nitrophenol显示文摘A silver-based metal-organic framework(Ag-MOFs), [Ag2(H3 ddcba)(dpp)2](1)(H5 ddcba = 3,5-(di(2',5'-dicarboxylphenyl)benozoic acid, dpp = 1,3-di(4-pyridyl)propane), was successfully constructed via hydrothermal assembly of a pentacaboxylate ligand, a N-donor ligand and Ag(I) ions, which possesses a pcu topology and exhibits excellent catalytic properties in aqueous solution for the degradation of onitrophenol(2-NP), m-nitrophenol(3-NP) and p-nitrophenol(4-NP). Related kinetics of such catalytic reactions, photoluminescent and thermal stability of compound 1 were also investigated.Dandan Huang Xueqian Wua Junwu Tian Xiaokun Wang Zhihang Zhou Dongsheng Li 2018Chinese Chemical Letters2018,29,6:7
3Research on DC Protection Strategy in Multi-Terminal Hybrid HVDC System显示文摘Multi-terminal hybrid high-voltage direct current(HVDC)systems have been developed quickly in recent years in power transmission area.However,for voltage-source converter(VSC)stations in hybrid HVDC systems,no direct current(DC)filters are required.In addition,the DC reactor is also not installed at the line end because the DC fault can be limited by the converter itself.This means that the boundary element at the line end is absent,and the single-ended protections used in line commutated converter(LCC)based HVDC(LCC-HVDC)systems or VSC-HVDC systems cannot distinguish the fault line in multi-terminal hybrid HVDC systems.This paper proposes a novel singleended DC protection strategy suitable for the multi-terminal hybrid HVDC system,which mainly applies the transient information and active injection concept to detect and distinguish the fault line.Compared with the single-ended protections used in LCC-HVDC and VSC-HVDC systems,the proposed protection strategy is not dependent on the line boundary element and is thus suitable for the multiterminal hybrid HVDC system.The corresponding simulation cases based on power systems computer aided design(PSCAD)/electromagnetic transients including DC(EMTDC)are carried out to verify the superiority of the proposed protection.Yuping Zheng Jiawei He Bin Li Tonghua Wua Wei Dai Ye Li 2021Engineering2021,7,8:4
4Hospital-Based Phenotypic Features and Treatment Outcomes of Chinese Women with Polycystic Ovary Syndrome: The Effect of Body Mass Index and Geographic Distribution显示文摘Genetic,lifestyle,and environmental factors contribute to the etiology of polycystic ovary syndrome(PCOS).Increased body mass index(BMI)exacerbates the reproductive and metabolic parameters and reduces the fecundity of women with PCOS.This is a secondary analysis of a large-sample,multicenter,randomized controlled trial conducted at 21 sites in Chinese mainland.A total of 1000 women diagnosed with PCOS were enrolled in this trial.Of these,998 women with PCOS were included in the analysis.Increased BMI was associated with more severe menstrual irregularities,elevated testosterone level,higher prevalence of metabolic syndrome,and poorer quality of life.The rates of ovulation per woman for the normal,overweight,and obese BMI groups were 83.0%,78.2%,and 63.6%,respectively(P<0.001),and the rates of live birth were 23.6%,18.1%,and 15.3%(P=0.030).Northern PCOS patients showed more severe reproductive,glucose,and lipid profiles;less exercise;and lower total ovulation rates compared with PCOS patients from Southern China(74.8%vs 81.2%,absolute difference 6.4%,95%confidence interval 1.2%–11.5%).The results show the typical phenotypic features of Han women with PCOS in Northern and Southern China.The women living in Northern China showed a higher BMI,more severe glycolipid metabolism profiles,and subsequently worse clinical outcomes by the same interventions than those living in Southern China.The difference in phenotypic features can be explained mostly by differences in BMI and the resulting difference in ovulation.Jingshu Gao Hongli Ma Yu Wang Xinming Yang Yijuan Cao Bei Zhang Conghui Han Xiaoke Wua 2021Engineering2021,7,2:3
5Effects of an ultra-high magnetic field up to 25 T on the phase transformations of undercooled Co-B eutectic alloy显示文摘While there have been multiple recent reports in the literature focusing on the effects of magnetic field on the phase transformation behaviors,the research conducted with an ultra-high magnetic field greater than 20 T is still preliminary.In the current study,the structure evolution of Co-B alloys are experimentally studied with undercooling.The effects of a 25 T magnetic field on the solidification behavior and the subsequent solid-state phase transformation behavior have been investigated.The 25 T magnetic field is confirmed to have little effect on the homogeneous nucleation,but have some influence on the heterogeneous nucleation of Co_(3) B and Co_(23)B6 phases by modifying the wetting angleθ.The decomposition of Co_(23)B6 phase in the subsequent cooling process can be effectively suppressed by applying the 25 T magnetic field.The present work might be helpful for not only theoretically understanding the influence of ultra-high magnetic field on the phase transformation behaviors but a potential technology of field-manipulation of magnetic materials.Yixuan He Yuhao Wua Fan Bu Chengxiong Zou Zhangchi Bian Qiliang Huang Tie Liu Qiang Wang Jun Wang Jinshan Li Eric Beaugnon 2021Journal of Materials Science & Technology2021,,34:2
