| 1 | Activated carbon adsorption of quinolone antibiotics in water:Performance,mechanism,and modeling显示文摘The extensive use of antibiotics has led to their presence in the aquatic environment, and introduces potential impacts on human and ecological health. The capability of powdered activated carbon(PAC) to remove six frequently used quinolone(QN) antibiotics during water treatment was evaluated to improve drinking water safety. The kinetics of QN adsorption by PAC was best described by a pseudo second-order equation, and the adsorption capacity was well described by the Freundlich isotherm equation. Isotherms measured at different p H showed that hydrophobic interaction, electrostatic interaction,and π–π dispersion force were the main mechanisms for adsorption of QNs by PAC. A p H-dependent isotherm model based on the Freundlich equation was developed to predict the adsorption capacity of QNs by PAC at different p H values. This model had excellent prediction capabilities under different laboratory scenarios. Small relative standard derivations(RSDs), i.e., 0.59%–0.92% for ciprofloxacin and 0.09%–3.89% for enrofloxacin,were observed for equilibrium concentrations above the 0.3 mg/L level. The RSDs increased to 11.9% for ciprofloxacin and 32.1% for enrofloxacin at μg/L equilibrium levels, which is still acceptable. This model could be applied to predict the adsorption of other chemicals having different ionized forms. | Hao Fu Xuebing Li Jun Wang Pengfei Lin Chao Chen Xiaojian Zhang I.H.(Mel)Suffet | 2017 | Journal of Environmental Sciences2017，29，6： | 25 |
| 2 | Effect of particle size on the microstructure and thermal conductivity of Al/diamond composites prepared by spark plasma sintering显示文摘Spark plasma sintering (SPS) was used to fabricate Al/diamond composites. The influence of diamond particle size on the microstructure and thermal conductivity (TC) of composites was investigated by combining experimental results with model prediction. The results show that both composites with 40 μm particles and 70 μm particles exhibit high density and good TC, and the composite with 70 μm particles indicates an excellent TC of 325 W·m-1·K-1. Their TCs lay between the theoretical estimated bounds. In contrast, the composite with 100 μm particles demonstrates low density as well as poor TC due to its high porosity and weak interfacial bonding. Its TC is even considerably less than the lower bound of the predicted value. Using larger diamond particles can further enhance thermal conductive performance only based on the premise that highly dense composites of strong interfacial bonding can be obtained. | CHU Ke JIA Chengchang LIANG Xuebing CHEN Hui GAO Wenji | 2009 | Rare Metals2009，28，6： | 22 |
| 3 | Effect of powder mixing process on the microstructure and thermal conductivity of Al/diamond composites fabricated by spark plasma sintering显示文摘Two powder mixing processes, mechanical mixing (MM) and mechanical alloying (MA), were used to prepare mixed Al/diamond powders, which were subsequently consolidated using spark plasma sintering (SPS) to produce bulk Al/diamond composites. The effects of the powder mixing process on the morphologies of the mixed powders, the microstructure and the thermal conductivity of the composites were investigated. The results show that the powder mixing process can significantly affect the microstructure and the thermal conductivity of the composites. Agglomerations of the particles occurred in mixed powders using MM for 30 min, which led to high pore content and weak interfacial bonding in the composites and resulted in low relative density and low thermal conductivity for the composites. Mixed powders of homogeneous distribution of diamond particles could be obtained using MA for 10 min and MM for 2 h. The composite prepared through MA indicated a high relative density but low thermal conductivity due to its defects, such as damaged particles, Fe impurity, and local interfacial debonding, which were mainly introduced in the MA process. In contrast, the composite made by MM for 2 h demonstrated high relative density and an excellent thermal conductivity of 325 W·m-1·K-1, owing to its having few defects and strong interfacial bonding. | CHU Ke, JIA Chengchang, LIANG Xuebing, and CHEN Hui School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China | 2010 | Rare Metals2010，29，1： | 17 |
| 4 | MicroRNA-663 induces immune dysregulation by inhibiting TGF-β1 production in bone marrow-derived mesenchymal stem cells in patients with systemic lupus erythematosus显示文摘Mesenchymal stem cells(MSCs)are critical for immune regulation.Although several microRNAs(miRNAs)have been shown to participate in autoimmune pathogenesis by affecting lymphocyte development and function,the roles of miRNAs in MSC dysfunction in autoimmune diseases remain unclear.Here,we show that patients with systemic lupus erythematosus(SLE)display a unique miRNA signature in bone marrow-derived MSCs(BMSCs)compared with normal controls,among which miR-663 is closely associated with SLE disease activity.MiR-663 inhibits the proliferation and migration of BMSCs and impairs BMSC-mediated downregulation of follicular T helper(Tfh)cells and upregulation of regulatory T(Treg)cells by targeting transforming growth factorβ1(TGF-β1).MiR-663 overexpression weakens the therapeutic effect of BMSCs,while miR-663 inhibition improves the remission of lupus disease in MRL/lpr mice.Thus,miR-663 is a key mediator of SLE BMSC regulation and may serve as a new therapeutic target for the treatment of lupus. | Linyu Geng Xiaojun Tang Kangxing Zhou Dandan Wang Shiying Wang Genhong Yao Weiwei Chen Xiang Gao Wanjun Chen Songtao Shi Nan Shen Xuebing Feng Lingyun Sun | 2019 | Cellular & Molecular Immunology2019，16，3： | 16 |
| 5 | Initiation of Parkinson’s disease from gut to brain byδ-secretase显示文摘Lewy pathology,composed ofα-Synuclein(α-Syn)inclusions,a hallmark of Parkinson’s disease(PD),progressively spreads from the enteric nervous system(ENS)to the central nervous system(CNS).However,it remains unclear how this process is regulated at a molecular level.Here we show thatδ-secretase(asparagine endopeptidase,AEP)cleaves bothα-Syn at N103 and Tau at N368,and mediates their fibrillization and retrograde propagation from the gut to the brain,triggering nigra dopaminergic neuronal loss associated with Lewy bodies and motor dysfunction.α-Syn N103 and Tau N368 robustly interact with each other and are highly elevated in PD patients’gut and brain.Chronic oral administration of the neurotoxin rotenone induces AEP activation andα-Syn N103/Tau N368 complex formation in the gut,eliciting constipation and dopaminergic neuronal death in an AEP-dependent manner.Preformed fibrils(PFFs)ofα-Syn N103/Tau N368 are more neurotoxic and compact,and aggregate more quickly along the vagus nerve than their FL/FL counterparts or the individual fragments’fibrils.Colonic injection of PFFs induces PD pathologies,motor dysfunctions,and cognitive impairments.Thus,δ-secretase plays a crucial role in initiating PD pathology progression from the ENS to the CNS. | Eun Hee Ahn Seong Su Kang Xia Liu Guiqin Chen Zhentao Zhang Bindu Chandrasekharan Ashfaqul M.Alam Andrew S.Neish Xuebing Cao Keqiang Ye | 2020 | Cell Research2020，30，1： | 9 |
| 6 | Predicted interfacial thermal conductance and thermal conductivity of diamond/Al composites with various interfacial coatings显示文摘The interfacial thermal conductance (ITC) and thermal conductivity (TC) of diamond/Al composites with various coatings were theoretically studied and discussed. A series of predictions and numerical analyses were performed to investigate the effect of thickness, sound velocity, and other parameters of coating layers on the ITC and TC. It is found that both the ITC and TC decline with increasing coating thickness, especially for the coatings with relatively low thermal conductivity. Nevertheless, if the coating thickness is close to zero, or quite a small value, the ITC and TC are mainly determined by the constants of the coating material. Under this condition, coatings such as Ni, TiC, Mo 2 C, SiC, and Si can significantly improve the ITC and TC of diamond/Al composites. By contrast, coatings like Ag will exert the negative effect. Taking the optimization of interfacial bonding into account, conductive carbides such as TiC or Mo 2 C with low thickness can be the most suitable coatings for diamond/Al composites. | LIANG Xuebing JIA Chengchang CHU Ke CHEN Hui | 2011 | Rare Metals2011，30，5： | 8 |

| 8 | Characterization of refined fish oil from small fish in Mauritania显示文摘In this study,the effects of chemical refining on the physicochemical indices,environmental pollutants,lipid functional groups,relaxation characteristics,fatty acid profiles,and triglyceride(TG)molecular species in crude oil extracted from small fish in Mauritania were evaluated.The acid,peroxide,and iodine values of crude oil were identified as 5.52 mg KOH/g,1.73 meq/kg,and 200.78 g/100 g oil,respectively.After refining,these values were determined to be 0.29 mg KOH/g,0.76 meq/kg,and 210.80 g/100 g oil,respectively.The polychlorinated biphenyls and arsenic content of crude oil were identified as 32.30μg/kg and 1.00 mg/kg,respectively.After refining,these were not detected.The content of eicosapentaenoic acid(EPA)and docosahexaenoic acid(DHA)accounted for as much as 87.55%of the polyunsaturated fatty acids in the refined oil,indicating that high-quality fish oil is suitable as a food supplement.The correlation coefficient of the infrared spectra before and after refining was 0.968,and the relaxation time and peak shape data were almost similar before and after purification.Meanwhile,there were no significant differences(P≥0.05)in fatty acid profiles between the crude and refined oils,except for C16:0(P<0.01).Based on UPLC-Q E-MS/MS detection,137 TG molecules were identified in both crude and refined oils.Among the detected TG molecular species,64 contained EPA or DHA,which accounted for 46.83%and 46.00%of the total TG content in crude and refined oils,respectively.After refining,the content of the molecular species decreased by 31.95 mg/10 g,among which the three most variable molecular species were TG(16:0/18:1/22:6),(16:1/16:2/18:1),and(18:4/16:0/20:5),accounting for 29.26%of the decline of the molecular species.Overall,the refining process had little effect on the fatty acid profile and distribution of TG molecular species in fish oil. | Xuebing Zhang Liu Lin Zhuanxia Chen Jing Zhang Xichang Wang Ningping Tao | 2022 | Aquaculture and Fisheries2022，7，6： | 3 |
| 9 | Critical Heat Flux(CHF)Correlations for Subcooled Water Flow Boiling at High Pressure and High Heat Flux显示文摘The subcooled water flow boiling is beneficial for removing the high heat flux from the divertor in the fusion reactor,for which an accurate critical heat flux(CHF)correlation is necessary.Up to now,there are many CHF correlations mentioned for subcooled water flow boiling in the open literatures.However,the CHF correlations’accuracies for the prediction of subcooled water flow boiling are not satisfactory at high heat flux and high pressure for reactor divertor.The present paper compiled 1356 CHF experimental data points from 15 independent open literatures and evaluated 10 existing CHF correlations in subcooled water flow boiling.From the evaluation,the W-2 CHF correlation performs best for the experimental CHF data in all existing critical heat flux correlations.However,the predicted mean absolute error(MAE)of the W-2 correlation is not very ideal for all database and the MAE of the W-2 correlation is from 30%to 50%for some database.In order to enhance the CHF prediction accuracy in subcooled water flow boiling at high heat flux and high pressure,the present paper developed a new CHF correlation.Compared with other existing CHF correlations,the new CHF correlation greatly enhances the prediction accuracy over a broad range of pressures and heat fluxes which are desired in the cooling of high heat flux devices,such as those in the fusion reactor divertor.The validation results show that the new correlation has a MAE of 10.05%and a root mean squared error(RMSE)of 16.61%,predicting 68.1%of the entire database within±10%and 81.5%within±15%.The MAE of the new CHF correlation is 7.4%less than that of the best existing one(W-2 correlation),further confirming its superior prediction accuracy and reliability.Besides,the new CHF correlation works well not only for a uniform power profile but also for a non-uniform power profile in subcooled water flow boiling at high pressure and high heat flux. | LIU Ping GUO Yusheng DING Wenlong TANG Mingyun SONG Yuntao PENG Xuebing JI Jiadong CHEN Qinghua MAO Xin | 2021 | Journal of Thermal Science2021，30，1： | 2 |
| 10 | Acoustic cloak constructed with thin-plate metamaterials显示文摘We propose a strategy for designing the cylindrical acoustic cloak with thin-plate metamaterials.The inhomogeneous cloaking shell as derived by transformation acoustics is first discretized into a three-layer anisotropic metafluid,and their material parameters are optimized by minimizing the external scatterings.Then these metafluids are practically realized by thin-plate structures according to the metamaterial concept.As an example,an acoustic cloak is designed with nine layers of thin plate and totally 900 plate units.Numerical simulations are performed to assess the cloaking performance of the designed structure. | Pei Li Xuebing Chen Xiaoming Zhou Gengkai Hu Ping Xiang | 2015 | International Journal of Smart and Nano Materials2015，6，1： | 2 |
| 11 | Synthesis of a Novel Polycarboxylate Superplasticizer with Carboxyl Group as Side Chain Terminal Group to Enhance Its Clay Tolerance显示文摘The dispersion ability of polycarboxylate superplasticizer(PCE) in fresh concrete was much impeded by clay impurities. To improve the dispersion of PCE in the clay-contained concrete, a novel PCE with carboxyl as a specific branched chain terminal group was synthesized, using modified polyether as the raw material which was prepared through esterification between hexahydrophthalic anhydride(HHPA) and isobutenyl polyoxyethylene ether(IPEG) with hydroxy as the terminal group. The esterification product and PCE molecular structure were characterized by infrared spectroscopy and ~1HNMR resonance. The results confirmed that the product molecular structure was a comb-type copolymer with long-chain terminal carboxyl group and PEO attached directly to the backbone chain. The as-synthesized PCEs had favorable dispersibility in cement than conventional PCE in the presence of montmorillonite(Mmt) clay. This can be attributed to the introduction of electronegative carboxyl to PCE long-chain terminal group, which reduces the adsorption of PCE on Mmt, and thus improves the tolerance of PCE to the Mmt. | 陈刚 雷家珩 DU Yong CHEN Xuebing | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，1： | 2 |

| 14 | Genomic Epidemiology of Carbapenemaseproducing Klebsiella pneumoniae in China显示文摘The rapid spread of carbapenemase-producing Klebsiella pneumoniae(cpKP)poses serious threats to public health;however,the underlying genetic basis for its dissemination is still unknown.We conducted a comprehensive genomic epidemiology analysis on 420 cpKP isolates collected from 70 hospitals in 24 provinces/autonomous regions/municipalities of China during 2009–2017 by short-/long-read sequencing.The results showed that most cpKP isolates were categorized into clonal group 258(CG258),in which ST11 was the dominant clone.Phylogenetic analysis revealed three major clades including the top one of Clade 3 for CG258 cpKP isolates.Additionally,carbapenemase gene analysis indicated that blaKPC was dominant in the cpKP isolates,and most blaKPC genes were located in five major incompatibility(Inc)groups of blaKPC-harboring plasmids.Importantly,three advantageous combinations of host–blaKPC-carrying plasmid(Clade 3.1+3.2–IncFIIpHN7A8,Clade 3.1+3.2–IncFIIpHN7A8:IncR,and Clade 3.3–IncFIIpHN7A8:IncpA1763-KPC)were identified to confer cpKP isolates the advantages in both genotypes(strong correlation/coevolution)and phenotypes(resistance/growth/competition)to facilitate the nationwide spread of ST11/CG258 cpKP.Intriguingly,Bayesian skyline analysis illustrated that the three advantageous combinations might be directly associated with the strong population expansion during 2007–2008 and subsequent maintenance of the population of ST11/CG258 cpKP after 2008.We then examined drug resistance profiles of these cpKP isolates and proposed combination treatment regimens for CG258/non-CG258 cpKP infections.Thus,the findings of our systematical analysis shed light on the molecular epidemiology and genetic basis for the dissemination of ST11/CG258 cpKP in China,and much emphasis should be given to the close monitoring of advantageous cpKP–plasmid combinations. | Cuidan Li Xiaoyuan Jiang Tingting Yang Yingjiao Ju Zhe Yin Liya Yue Guannan Ma Xuebing Wang Ying Jing Xinhua Luo Shuangshuang Li Xue Yang Fei Chen Dongsheng Zhou | 2022 | Genomics, Proteomics & Bioinformatics2022，20，6： | 1 |

| 18 | An ultra-fast charging strategy for lithium-ion battery at low temperature without lithium plating显示文摘Conventional charging methods for lithium-ion battery(LIB)are challenged with vital problems at low temperatures:risk of lithium(Li)plating and low charging speed.This study proposes a fast-charging strategy without Li plating to achieve high-rate charging at low temperatures with bidirectional chargers.The strategy combines the pulsed-heating method and the optimal charging method via precise control of the battery states.A thermo-electric coupled model is developed based on the pseudo-twodimensional(P2D)electrochemical model to derive charging performances.Two current maps of pulsed heating and charging are generated to realize real-time control.Therefore,our proposed strategy achieves a 3 C equivalent rate at 0℃ and 1.5 C at-10℃ without Li plating,which is 10–30 times faster than the traditional methods.The entropy method is employed to balance the charging speed and the energy efficiency,and the charging performance is further enhanced.For practical application,the power limitation of the charger is considered,and a 2.4 C equivalent rate is achieved at 0℃ with a 250 kW maximum power output.This novel strategy significantly expands LIB usage boundary,and increases charging speed and battery safety. | Yudi Qin Pengyu Zuo Xiaoru Chen Wenjing Yuan Rong Huang Xiaokan Yang Jiuyu Du Languang Lu Xuebing Han Minggao Ouyang | 2022 | Journal of Energy Chemistry2022，31，9： | 1 |

| 20 | Dietary supplementation with 2-hydroxy-4-methyl(thio)butanoic acid and DL-methionine improves productive performance,egg quality and redox status of commercial laying ducks显示文摘This experiment aimed to study the effects of supplemental methionine sources,2-hydroxy-4 methyl(thio)butanoic acid(HMTBa)and DL-Methionine(DL-Met),on productive performance,egg quality,and redox status of laying ducks.A total of 792 healthy 25-wk-old Longyan laying ducks with similar body weights were randomly allotted to 11 treatment groups.Each treatment group had 6 replicates of 12 ducks.The trial lasted for 16 wk.Ducks were fed a basal deficient diet(Met:0.24%;Met+Cys:0.51%)or supplemented with DL-Met or HMTBa at 0.05%,0.12%,0.19%,0.26%,and 0.33%of diet,respectively.Compared with the basal diet,supplementation with either DL-Met or HMTBa increased the average egg weight,egg mass,and decreased feed to egg ratio during the whole trial period(P<0.05).Albumen weight and its ratio to total egg weight were increased,but yolk and shell ratio,albumen height,Haugh unit and shell breaking strength were decreased(P<0.05).Dietary DL-Met or HMTBa supplementation increased taurine,methionine,leucine,tryptophan and arginine content,and decreased serine and lysine content in plasma(P<0.05).The redox status of laying ducks was improved by enhancing the glutathione peroxidase and catalase activities,glutathione content and its ratio relative to glutathione(oxidized)content and decreasing malondialdehyde content and increasing mRNA expression of superoxide dismutase-1,glutathione peroxidase-1,hemeoxygenase-1 and nuclear factor-like 2 in liver and ileum with the supplementation of DL-Met or HMTBa(P<0.05).Liver health status measured by average area proportion lipid droplet was improved with supplementation of DL-Met or HMTBa(P<0.05).Villus height and villus height to crypt depth ratio in the ileum and the ileal gene expression of tight junction protein and occludin were increased with DL-Met or HMTBa supplementation(P<0.05).Taken together,these results suggested that the efficacy of dietary supplementation of HMTBa was similar to DL-Met,and it ranged from 98%to 100%for productive performance and egg albumen ratio in laying ducks(25 to 41 wk). | Yanan Zhang Zhiwei Zhuang Tahir Mahmood Yves Mercier Yongyan Jin Xuebing Huang Kaichao Li Shuang Wang Weiguang Xia Shenglin Wang Miao Yu Wei Chen Chuntian Zheng | 2023 | Animal Nutrition2023，，3： | 1 |
