| 1 | Theoretical prediction,synthesis,and crystal structure determination of new MAX phase compound V2SnC显示文摘Guided by the theoretical prediction,a new MAX phase V2SnC was synthesized experimentally for the first time by reaction of V,Sn,and C mixtures at 1000°C.The chemical composition and crystal structure of this new compound were identified by the cross-check combination of first-principles calculations,X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDS),and high resolution scanning transmission electron microscopy(HR-STEM).The stacking sequence of V2C and Sn layers results in a crystal structure of space group P63/mmc.The a-and c-lattice parameters,which were determined by the Rietveld analysis of powder XRD pattern,are 0.2981(0)nm and 1.3470(6)nm,respectively.The atomic positions are V at 4f(1/3,2/3,0.0776(5)),Sn at 2d(2/3,1/3,1/4),and C at 2a(0,0,0).A new set of XRD data of V2SnC was also obtained.Theoretical calculations suggest that this new compound is stable with negative formation energy and formation enthalpy,satisfied Born-Huang criteria of mechanical stability,and positive phonon branches over the Brillouin zone.It also has low shear deformation resistance c44(second-order elastic constant,cij)and shear modulus(G),positive Cauchy pressure,and low Pugh’s ratio(G/B=0.500<0.571),which is regarded as a quasi-ductile MAX phase.The mechanism underpinning the quasi-ductility is associated with the presence of a metallic bond. | Qiang Xu Yanchun Zhou Haiming Zhang Anna Jiang Quanzheng Tao Jun Lu Johanna Rosén Yunhui Niu Salvatore Grasso Chunfeng Hu | 2020 | Journal of Advanced Ceramics2020，9，4： | 8 |
| 2 | Engineering an enthesis-like graft for rotator cuff repair:An approach to fabricate highly biomimetic scaffold capable of zone-specifically releasing stem cell differentiation inducers显示文摘Rotator cuff(RC)attaches to humerus across a triphasic yet continuous tissue zones(bone-fibrocartilage-tendon),termed“enthesis”.Regrettably,rapid and functional enthesis regeneration is challenging after RC tear.The existing grafts bioengineered for RC repair are insufficient,as they were engineered by a scaffold that did not mimic normal enthesis in morphology,composition,and tensile property,meanwhile cannot simultaneously stimulate the formation of bone-fibrocartilage-tendon tissues.Herein,an optimized decellularization approach based on a vacuum aspiration device(VAD)was developed to fabricate a book-shaped decellularized enthesis matrix(O-BDEM).Then,three recombinant growth factors(CBP-GFs)capable of binding collagen were synthesized by fusing a collagen-binding peptide(CBP)into the N-terminal of BMP-2,TGF-β3,or GDF-7,and zone-specifically tethered to the collagen of O-BDEM to fabricate a novel scaffold(CBP-GFs/O-BDEM)satisfying the above-mentioned requirements.After ensuring the low immunogenicity of CBP-GFs/O-BDEM by a novel single-cell mass cytometry in a mouse model,we interleaved urine-derived stem cell-sheets into this CBP-GFs/O-BDEM to bioengineer an enthesis-like graft.Its high-performance on regenerating enthesis was determined in a canine model.These findings indicate this CBP-GFs/O-BDEM may be an excellent scaffold for constructing enthesis-like graft to patch large/massive RC tears,and provide breakthroughs in fabricating graded interfacial tissue. | Can Chen Qiang Shi Muzhi Li Yang Chen Tao Zhang Yan Xu Yunjie Liao Shulin Ding Zhanwen Wang Xing Li Chunfeng Zhao Lunquan Sun Jianzhong Hu Hongbin Lu | 2022 | Bioactive Materials2022，7，10： | 4 |
| 3 | Potential applications of porous organic polymers as adsorbent for the adsorption of volatile organic compounds显示文摘Volatile organic compounds(VOCs)with high toxicity and carcinogenicity are emitted from kinds of industries,which endanger human health and the environment.Adsorption is a promising method for the treatment of VOCs due to its low cost and high efficiency.In recent years,activated carbons,zeolites,and mesoporous materials are widely used to remove VOCs because of their high specific surface area and abundant porosity.However,the hydrophilic nature and low desorption rate of those materials limit their commercial application.Furthermore,the adsorption capacities of VOCs still need to be improved.Porous organic polymers(POPs)with extremely high porosity,structural diversity,and hydrophobic have been considered as one of the most promising candidates for VOCs adsorption.This review generalized the superiority of POPs for VOCs adsorption compared to other porous materials and summarized the studies of VOCs adsorption on different types of POPs.Moreover,the mechanism of competitive adsorption between water and VOCs on the POPs was discussed.Finally,a concise outlook for utilizing POPs for VOCs adsorption was discussed,noting areas in which further work is needed to develop the next-generation POPs for practical applications. | Shuangchun Lu Qingling Liu Rui Han Miao Guo Jiaqi Shi Chunfeng Song Na Ji Xuebin Lu Degang Ma | 2021 | Journal of Environmental Sciences2021，33，7： | 4 |
| 4 | The efficacy and safety of pramipexole ER versus IR in Chinese patients with Parkinson’s disease: a randomized, double-blind, double-dummy, parallel-group study显示文摘Objective:To evaluate the non-inferiority of pramipexole extended-release(ER)versus immediate-release(IR)in Chinese patients with Parkinson’s disease(PD)in a double-blind,randomized,parallel-group study.Methods:Subjects were Chinese patients with idiopathic PD with diagnosis≥2 years prior to trial,age≥30 years old at diagnosis,and Modified Hoehn and Yahr score 2-4 during‘on’-time.Subjects received treatment with pramipexole ER(n=234)or IR(n=239).Non-inferiority was based on the primary endpoint,the change from baseline to end of maintenance(week 18)in the UPDRS(Parts II+III)total score.Results:For the primary endpoint,the adjusted mean changes(standard error)of UPDRS Parts II+III at week 18 were−13.81(0.655)and−13.05(0.643)for ER and IR formulations,respectively,using ANCOVA adjusted for treatment and centre(fixed effect)and baseline(covariate).The adjusted mean between group difference was 0.8 for the 2-sided 95%CI(−1.047,2.566).Since the lower limit of the 2-sided 95%CI(−1.047)for treatment difference was higher than the non-inferiority margin of−4,non-inferiority between pramipexole ER and IR was demonstrated.The incidence of adverse events(AEs)was 68.8%in the ER arm and 73.6%in the IR arm with few severe AEs(ER:2.1%;IR:3.8%).Conclusion:Based on the UPDRS II+III score,pramipexole ER was non-inferior to pramipexole IR.The safety profiles of pramipexole ER and IR were similar.These results were based on comparable mean daily doses and durations of treatment for both formulations. | Ying Wang Shenggang Sun Suiqiang Zhu Chunfeng Liu Yiming Liu Qing Di Huifang Shang Yan Ren Changhong Lu Mark Forrest Gordon Nolwenn Juhel Shengdi Chen for the Pramipexole ER Study Team | 2014 | Translational Neurodegeneration2014，3，1： | 3 |
| 5 | Research on the Characteristics of Hot Deformation in BT20 Titanium alloy and Its Optimum Spinning Temperature Range显示文摘Hot compression tests were conducted on a Gleeble-1500 simulator to investigate the hot deformation behavior of BT20 Ti alloy (Ti-6Al-2Zr-1Mo-1V) in the temperature range from 550 to 1000℃ at constant strain rate in the range of 0.01~1 s-1, and then the optimum spinning temperature range was determined. Moreover, tube spinning experiments were executed to verify the reasonability of the optimum temperature range. The results show that the flow stress declines gradually with increasing deformation temperature and decreasing strain rate. In α+β phase region the dynamic recrystallization is the main softening mechanism and in β phase region the hot deformation softening is controlled by dynamic recovery. In α+βphase region with reducing strain rate dynamic recrystallization is fully developed. The optimum temperature of hot spinning is 850~900℃ and that of warm spinning is 600~650℃.Meanwhile, at the temperature above 600℃ tubular workpieces of BT20 Ti alloy have been spun without surface cracks and microstructure inhomogeneity, which proves that the optimum spinning temperature range obtained through hot compression experiments is reasonable. | Wenchen XU+, Debin SHAN, Yan LU and Chunfeng LISchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China | 2005 | Journal of Materials Science & Technology2005，21，6： | 2 |

| 11 | African swine fever virus MGF505-3R inhibits cGAS-STING-mediated IFN-βpathway activation by degrading TBK1显示文摘African swine fever virus(ASFV)is an important pathogen causing acute infectious disease in domestic pigs and wild boars that seriously endangers the global swine industry.As ASFV is structurally complex and encodes a large number of functional proteins,no effective vaccine has been developed to date.Thus,dissecting the mechanisms of immune escape induced by ASFV proteins is crucial.A previous study showed that the ASFV-encoded protein is an important factor in host immunity.In this study,we identified a negative regulator,MGF505-3R,that significantly downregulated cGAS/STING-and poly(dG:dC)-mediated IFN-βand interferon stimulation response element(ISRE)reporter activity and suppressed IFNB1 and IFIT2 mRNA levels.In addition,TBK1,IRF3 and IκBαphosphorylation levels were also inhibited.Mechanistically,MGF505-3R interacted with cGAS/TBK1/IRF3 and targeted TBK1 for degradation,thereby disrupting the cGAS-STING-mediated IFN-βsignaling pathway,which appears to be highly correlated with autophagy.Knockdown MGF505-3R expression enhanced IFN-βand IL-1βproduction.Taken together,our study revealed a negative regulatory mechanism involving the MGF505-3R-cGAS-STING axis and provided insights into an evasion strategy employed by ASFV that involves autophagy and innate signaling pathways. | Mingyang Cheng Jiawei Luo Yuetong Duan Yu Yang Chunwei Shi Yu Sun Yiyuan Lu Junhong Wang Xiaoxu Li Jianzhong Wang Nan Wang Wentao Yang Yanlong Jiang Guilian Yang Yan Zeng Chunfeng Wang Xin Cao | 2022 | Animal Diseases2022，2，3： | 1 |

| 13 | Enhanced hepatotoxicity induced by repeated exposure to polychlorinated biphenyls and 2,3,7,8-tetrachlorodibenzo-p-dioxin in combination in male rats显示文摘2,3,7,8-Tetrachlorodibenzo-p-dioxin(TCDD) and polychlorinated biphenyls(PCBs) are among persistent polyhalogenated aromatic hydrocarbons that exist as complex mixtures in the environment worldwide.The present study was attempted to investigate the hepatotoxicity following repeated exposure to TCDD and PCBs in combination in male rats,and to reveal the involvement of potential mechanisms.Male Sprague-Dawley rats were exposed to TCDD(10 μg/kg) and Aroclor 1254(10 mg/kg,a representative mixture of PCBs) alone or in combination by intragastric administration.After 12-day exposure,all treatments produced significant hepatotoxicity as characterized by changes of plasma biochemistry and histopathological changes.These effects were more prominent in the combined group.Furthermore,all treatments induced hepatic cytochrome P450 1A1(CYP1A1) expression,and the maximal level of CYP1A1 expression was observed in the combined group,as in the case of the most severe hepatotoxicity evoked by the combined exposure.These findings indicated that the hepatotoxicity induced by TCDD and Aroclor 1254 might be ascribed to the high expression of hepatic CYP1A1.The present study demonstrates the enhanced hepatotoxicity after exposure to TCDD and PCBs in combination in rats. | Yimei Wang Chunfeng Lu Zhiguo Sheng Gang Liu Ze Fu Benzhan Zhu Shuangqing Peng | 2011 | Journal of Environmental Sciences2011，23，1： | 0 |
| 14 | Response of water-use efficiency to phenology in the natural forest and grassland of the Loess Plateau in China显示文摘Ecosystem water use efficiency(WUE)is an integrated physiological metric for the coupling cycle between terrestrial carbon,water,and energy.How WUE responds to vegetation phenology(e.g.,SOS,EOS-start,end of growing season,and GSL-growing season length)shifting in temperate semi-arid regions is a hot spot in relative research fields.Based on remotesensing products and in-situ measured climate data,this study discussed how gross primary productivity(GPP),evapotranspiration(ET),and WUE(quantified by GPP/ET)would change with the altering vegetation phenology and climate in the untouched semi-arid forests and grasslands of the Chinese Loess Plateau during 2001–2020.Our results show that vegetation tended to green-up earlier and brown-down later from 2001 to 2020,causing an extended GSL.The forests had an earlier SOS,later EOS,and longer GSL than the grasslands,but the latter had a bigger variation amplitude.The WUE in the study area decreased significantly during spring and summer,while the grassland WUE increased in autumn;the annual mean reduction rate in grassland WUE was approximately twice that of woodland.Earlier SOS could increase forest WUE but reduce grassland WUE in spring,mainly because leaf unfolding has a more pronounced limitation on soil evaporation beneath the forest canopy.EOS had less impact on WUE,and no apparent difference existed between these two ecosystems.Climate change could affect WUE directly by changing GPP and ET and indirectly by regulating vegetation phenology.Warming can increase GPP and ET,causing an earlier SOS,further promoting GPP and ET(except forest ET).Precipitation significantly affected forest GPP and ET in spring,grassland GPP and ET in summer,and grassland ET in autumn;precipitation affects spring grassland WUE mainly via regulating SOS.Enhanced solar radiation could suppress grassland GPP in spring,promote forest ET in autumn,and regulate grassland WUE by affecting phenology.This study is meaningful for improving the process-based vegetation model and studying arid and semi-arid ecosystems’responses to a changing climate. | Xingyan TAN Yangwen JIA Cunwen NIU Dawen YANG Wen LU Chunfeng HAO | 2023 | Science China Earth Sciences2023，66，9： | 0 |
| 15 | Simplified theoretical analysis and numerical study on the dynamic behavior of FCP under blast loads显示文摘Precast concrete structures have developed rapidly in the last decades due to the advantages of better quality,non-pollution and fast construction with respect to conventional cast-in-place structures.In the present study,a theoretical model and nonlinear 3D model are developed and established to assess the dynamic behavior of precast concrete slabs under blast load.At first,the 3D model is validated by an experiment performed by other researchers.The verified model is adopted to investigate the blast performance of fabricated concrete panels(FCPs)in terms of parameters of the explosive charge,panel thickness,and reinforcement ratio.Finally,a simplified theoretical model of the FCP under blast load is developed to predict the maximum deflection.It is indicated that the theoretical model can precisely predict the maximum displacement of FCP under blast loads.The results show that the failure modes of the panels varied from bending failure to shear failure with the mass of TNT increasing.The thickness of the panel,reinforcement ratio,and explosive charges have significant effects on the anti-blast capacity of the FCPs. | Chunfeng ZHAO Xin YE Avinash GAUTAM Xin LU YLMO | 2020 | Frontiers of Structural and Civil Engineering2020，14，4： | 0 |
| 16 | Highly crystalline and water-wettable benzobisthiazole-based covalent organic frameworks for enhanced photocatalytic hydrogen production显示文摘Two-dimensional covalent organic frameworks are promising for photocatalysis by virtue of their structural and functional diversity,but generally suffer from low activities relative to their inorganic competitors.To fulfill their full potential re quires a rational tailoring of their structures at different scales as well as their surface properties.Herein,we demonstrate benzobisthiazole-based covalent organic frameworks as a superior photocatalyst for hydrogen production.The product features high crystallinity with ordered 2.5-nm-wide cylindrical mesopores and great water wettability.These structural advantages afford our polymeric photo catalyst with fast charge carrier dynamics as evidenced by a range of spectroscopic characterizations and excellent catalytic performances when suspended in solution or supported on melamine foams.Under visible-light irradiation,it enables efficient and stable hydrogen evolution with a production rate of 487μmol h^(-1)(or a mass-specific rate of 48.7 mmol g^(-1)h^(-1))—far superior to the previous state of the art.We also demonstrate that hydrogen production can be stoichiometrically coupled with the oxidation conversion of biomass as exemplified by the conversion of furfuryl alcohol to 2-furaldehyde. | Wei Huang Yongpan Hu Zhengyuan Qin Yujin Ji Xuan Zhao Yunling Wu Qing He Youyong Li Chunfeng Zhang Jun Lu Yanguang Li | 2023 | National Science Review2023，10，1： | 0 |
| 17 | Mixed 2D-Dion–Jacobson/3D Sn-Pb alloyed perovskites for efficient photovoltaic solar devices显示文摘Tin-lead(Sn-Pb)alloyed perovskites with tunable bandgaps hold great potential for constructing highly efficient single-junction and tandem photovoltaic devices.However,the efficiency and stability of Sn-Pb perovskite solar cells(PSCs)are greatly hampered by severe nonradiative recombination due to the easy oxidation of Sn(II).In this work,we report the construction of mixed dimensional two-dimensional(2D)Dion–Jacobson(DJ)and three-dimensional(3D)perovskites to improve the efficiency and stability of Sn-Pb alloyed PSCs.Introducing a small amount of 1,4-butanediammonium diiodide as spacer cations of DJ perovskites into precursor,the prepared mixed dimensional Sn-Pb alloyed perovskites exhibit reduced trap-state density due to the passivation of 2D DJ perovskites.As a result,nonradiative charge recombination is greatly suppressed.The prepared Sn-Pb alloyed PSCs based on 2D-DJ/3D heterojunction deliver a power conversion efficiency of 19.02%with an impressive fill factor of 80%.As well,improved device stability is realized due to the presence of DJ perovskites which serves as a protection barrier against oxidation and water invasion. | Zhili Lu Chaohui Li Hongwei Lai Xinming Zhou Chunfeng Wang Xianhu Liu Fei Guo Caofeng Pan | 2023 | Nano Research2023，16，2： | 0 |
| 18 | Boost photothermal theranostics via self-assembly-induced crystallization(SAIC)显示文摘Owing to the intrinsic advantages of spatiotemporal selectivity,photothermal theranostics have become the advancing edge of precision medicine for cancer.Developing photothermal transduction agents(PTAs)with near-infrared(NIR)absorption,high photothermal conversion efficiency,robust photothermal stability,and good accumulation in tumors,is particularly valuable.Herein,we report a new concept,self-assembly-induced crystallization(SAIC),which can serve as a mechanism that dramatically boosts photothermal behaviors of PTA in NIR region.As a proof of concept,three heptamethine cyanine molecules with internal degrees of freedom(geometry and intramolecular interaction)are designed to fine-tune their crystallinity.Notably,Cy7-TCF-EMBI molecules with rigid and planar skeletons self-assemble into a crystalline state to maximize their packing density and improve the charge transfer,both of which contribute to nonradiative decay for energy dissipation as heat.The high packing density also renders an ideal scaffold for controlling intermolecular interactions to exhibit better photothermal stability,and endows an anisotropic three-dimensional architecture for passive tumor targeting.This“SAIC”strategy may offer a conceptually novel,practically simple but effective approach to unveil the structure–property relationship that could provide some general rules in rational design of PTAs,and paves the way for a next generation of supramolecular medicine for photothermal theranostics. | Xueluer Mu Fapu Wu Ying Tang Rui Wang Yajie Li Kaixuan Li Chunfeng Li Yingxi Lu Xianfeng Zhou Zhibo Li | 2022 | Aggregate2022，3，5： | 0 |
