1Ni-based cathode materials for Na-ion batteries显示文摘Na-ion batteries(NIBs)have attracted significant attention owing to Na being an abundant resource that is uniformly distributed in the Earth's crust.Several 3d transition metal(TM)ions have been thoroughly investigated as charge compensators in single or multiple composition systems to enhance the electrochemical performance of cathodes for the practical applications.In this review,the composition-structure-property relationship of Ni-based cathodes has been reviewed as a design perspective for NIB'S cathodes.The typical Ni-based cathode materials have bee n systematically summarized and comparatively analyzed,and it is dem on strated that Ni io ns can be used to provide charge compensation.Moreover,Ni-based cathodes present high reversible capacity owing to the multi-electron redox reactions and suitable redox pote ntial of Ni-ions redox.However,con sidering the abundan ce,cost,and hygroscopic properties of Ni eleme nt,the content of 0.15-0.35 per formula can be optimal for enhancing the performance of cathodes.Lastly,further perspectives on designing Ni?containing cathodes,including Ni-rich layered cathodes,have been discussed,which could promote the practical applications of NIBs for grid-scale energy storage in future.Chenglong Zhao Yaxiang Lu Liquan Chen Yong-Sheng Hu 2019Nano Research2019,12,9:8
2High-temperature treatment induced carbon anode with ultrahigh Na storage capacity at low-voltage plateau显示文摘Sodium-ion batteries(NIBs) show great prospect on the energy storage applications benefiting from their low cost and the abundant Na resources despite the expected lower energy density compared with lithium-ion batteries(LIBs). To further enhance the competitive advantage, especially in energy density,developing the high-capacity carbon anode materials can be one of the effective approaches to realize this goal. Herein, we report a novel carbon anode made from charcoal with a high capacity of ~400 m Ah g^(-1), wherein about 85%(>330 mAh g^(-1)) of its total capacity is derived from the long plateau region below ~0.1 V, which differs from those of typical hard carbon materials(~300 m Ah g^(-1)) in NIBs but is similar to the graphite anode in LIBs. When coupled with air-stable Na_(0.9)Cu_(0.22)e_(0.30)Mn_(0.48)O_2 oxide cathode, a high-energy density of ~240 Wh kg^(-1) is achieved with good rate capability and cycling stability. The discovery of this promising carbon anode is expected to further improve the energy density of NIBs towards large-scale electrical energy storage.Chenglong Zhao Qidi Wang Yaxiang Lu Baohua Li Liquan Chen Yong-Sheng Hu 2018Science Bulletin2018,63,17:7

4A phase inversion based sponge-like polysulfonamide/SiO_2 composite separator for high performance lithium-ion batteries显示文摘In this work,a sponge-like polysulfonamide(PSA)/SiO_2 composite membrane is unprecedentedly prepared by the phase inversion method,and successfully demonstrated as a novel separator of lithium-ion batteries(LIBs).Compared to the commercial polypropylene(PP) separator,the sponge-like PSA/SiO_2 composite possesses better physical and electrochemical properties,such as higher porosity,ionic conductivity,thermal stability and flame retarding ability.The LiCoO_2/Li half-cells using the sponge-like composite separator demonstrate superior rate capability and cyclability over those using the commercial PP separator.Moreover,the sponge-like composite separator can ensure the normal operation of LiCoO_2/Li half-cell at an extremely high temperature of 90 °C,while the commercial PP separator cannot.All these encouraging results suggest that this phase inversion based sponge-like PSA/SiO_2 composite separator is really a promising separator for high performance LIBs.Xiao Wang Gaojie Xu Qingfu Wang Chenglong Lu Chengzhong Zong Jianjun Zhang Liping Yue Guanglei Cui 2018Chinese Journal of Chemical Engineering2018,26,6:6
5The origin and distribution of natural gas in the frontal uplift area of the Kuqa depression,Tarim Basin显示文摘The frontal uplift of the Kuqa depression is an important oil and gas producing area. In this study, the distribution and origin of natural gas were discussed based on natural gas components and isotope data. The main components of natural gas were hydrocarbons with relatively high contents of C2+ component. Most gases were derived from terrestrial source rocks, and some came from marine rocks. The contents of non-hydrocarbon gases were high in the central part of the frontal uplift area and low in the two terminals. The distribution of oil composition was similar to that of natural gas, which was mainly controlled by the types of source rocks. Dry coefficient and maturity of natural gas in the frontal uplift were lower than those of gas in the Kelasu tectonic belt of the Kuqa depression, which was mainly affected by the difference of tectonic movements in both areas. In the frontal uplift, the traps were formed in the early stage and could capture the early formed oil and gas, and structural adjustment was slight in later stages, so the oil and gas could be effectively preserved. Multiperiodic oil and gas filling led to the complex distribution of natural gas.CUI Jie ZHU Guangyou ZHANG Bin SU Jin LU Yuhong MA Chenglong 2010Chinese Journal Of Geochemistry2010,29,3:5
6Advanced Na metal anodes显示文摘Na metal anode, benefiting from its high theoretical capacity and lowest electrochemical potential, is one of the most favorable candidates for future Na-based batteries with high energy density. Dendrite growth, volume change and high reactivity are the formidable challenges in terms of good cycling performance and high Coulombic efficiency as well as an expected safety guarantee of Na metal anode for the practical application. Solid electrolyte interphase(SEI) layer as an indispensable component of a battery,its formation and stability play the critical role in the feasibility of Na metal anode. In this review, we first discuss the current consideration and challenges of Na metal anode, and then summarize several strategies to suppress dendrite growth and improve electrochemical performance, including interface engineering, electrolyte composition, electrode construction, and so on. Finally, the conclusion and future perspective of potential development on Na metal anode are proposed.Chenglong Zhao Yaxiang Lu Jinming Yue Du Pan Yuruo Qi Yong-Sheng Hu Liquan Chen 2018Journal of Energy Chemistry2018,27,6:5

8Highly active N-doped carbon encapsulated Pd-Fe intermetallic nanoparticles for the oxygen reduction reaction显示文摘Developing highly efficient non-R catalysts for fuel cells and metal-air batteries is highly desirable but still challenging due to the sluggish oxygen reduction reaction(ORR).Herein,a facile and efficient strategy is demonstrated to prepare N-doped carbon encapsulated ordered Pd-Fe intermetallic(O-Pd-Fe@NC/C)nanoparticles via a one-step thermal annealing method.The obtained O-Pd-Fe@NC/C nanoparticles show enhanced ORR activity,durability and anti-poisoning capacity in both acid and alkaline medium.When O-Pd-Fe@NC/C serving as cathode catalyst for Zn-air battery,it exhibits higher voltage platform and superior cycling performance with respect to the Zn-air battery based on the mixture of Pt/C and Ir/C catalysts.The enhanced electrocatalytic performance can be ascribed to the formation of face-centered tetragonal(fct)Pd-Fe nanoparticles,the protective action of the N-doped carbon layer and the interface confinement effect between them.The in situ formed N-doped carbon shell not only restrains the Pd-Fe ordered intermetallics from aggregating effectively during the thermal annealing process,but also provides a strong anchoring effect to avoid the detachment of Pd-Fe nanoparticles from the carbon support during the potential cycling.This facile carbon encapsulation strategy may also be extended to the preparation of a wide variety of N-doped carbon encapsulated intermetallic compounds for fuel cell application.Yezhou Hu Yun Lu Xueru Zhao Tao Shen Tonghui Zhao Mingxing Gong Ke Chen Chenglong Lai Jian Zhang Huolin L.Xin Deli Wang 2020Nano Research2020,13,9:3
9An insight into failure mechanism of NASICON-structured Na3V2(PO4)3 in hybrid aqueous rechargeable battery显示文摘NASICON (Na-super-ionic-conductors)-structured materials have attracted extensive research interest due to their great application potential in secondary batteries. However, the mechanism of capacity fading for NASICON-structured electrode materials has been rarely studied. In this paper, we synthesized the NASICON-structured Na3V2(PO4)3/C composite by simple sol-gel and high-temperature solid-phase method and investigated its electrochemical performance in Na-Zn hybrid aqueous rechargeable batteries. After characterizing the structure, morphology and composition variations as well as the interfacial resistance changes of Na3V2(PO4)3/C cathode during cycling, we propose a mechanical and interfacial degradation mechanism for capacity fading of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. This work will shed light on enhancing the mechanical and in terfacial stability of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries.Xinxin Zhang Jun Ma Pu Hu Bingbing Chen Chenglong Lu Xinhong Zhou Pengxian Han Lihua Chen Guanglei Cui 2019Journal of Energy Chemistry2019,28,5:3

11Development of a polycaprolactone/poly(p-dioxanone)bioresorbable stent with mechanically self-reinforced structure for congenital heart disease treatment显示文摘Recent progress in bioresorbable stents(BRSs)has provided a promising alternative for treating coronary artery disease.However,there is still lack of BRSs with satisfied compression and degradation performance for pediatric patients with congenital heart disease,leading to suboptimal therapy effects.Here,we developed a mechanically self-reinforced composite bioresorbable stent(cBRS)for congenital heart disease application.The cBRS consisted of poly(p-dioxanone)monofilaments and polycaprolactone/poly(p-dioxanone)core-shell composite yarns.Interlacing points in cBRS structure were partially bonded,offering the cBRS with significantly higher compression force compared to typical braids and remained good compliance.The suitable degradation profile of the cBRS can possibly preserve vascular remodeling and healing process.In addition,the controllable structural organization provides a method to customize the performance of the cBRS by altering the proportion of different components in the braids.The in vivo results suggested the cBRS supported the vessel wall similar to that of metallic stent.In both abdominal aorta and iliac artery of porcine,cBRS was entirely endothelialized within 1 month and maintained target vessels with good patency in the 12-month follow-up.The in vivo degradation profile of the cBRS is consistent with static degradation results in vitro.It is also demonstrated that there is minimal impact of pulsatile pressure of blood flow and variation of radial force on the degradation rate of the cBRS.Moreover,the lumen of cBRS implanted vessels were enlarged after 6 months,and significantly larger than the vessels implanted with metallic stent in 12 months.Fan Zhao Jing Sun Wen Xue Fujun Wang Martin W.King Chenglong Yu Yongjie Jiao Kun Sun Lu Wang 2021Bioactive Materials2021,6,9:3
12Facile self-template fabrication of hierarchical nickel-cobalt phosphide hollow nanoflowers with enhanced hydrogen generation performance显示文摘Developing facile methods to construct hierarchical-structured transition metal phosphides is beneficial for achieving high-efficiency hydrogen evolution catalysts.Herein,a self-template strategy of hydrothermal treatment of solid Ni-Co glycerate nanospheres followed by phosphorization is delivered to synthesize hierarchical Ni Co P hollow nanoflowers with ultrathin nanosheet assembly.The microstructure of Ni Co P can be availably tailored by adjusting the hydrothermal treatment temperature through affecting the hydrolysis process of Ni-Co glycerate nanospheres and the occurred Kirkendall effect.Benefitting from the promoted exposure of active sites and affluent mass diffusion routes,the HER performance of the Ni Co P hollow nanoflowers has been obviously enhanced in contrast with the solid Ni Co P nanospheres.The fabricated Ni Co P hollow nanoflowers yield the current density of 10 m A cmà2at small overpotentials of 95 and 127 m V in 0.5 mol Là1H2SO4and 1.0 mol Là1KOH solution,respectively.Moreover,the two-electrode alkaline cell assembled with the Ni Co P and Ir/C catalysts exhibits sustainable stability for overall water splitting.The work provides a simple but efficient method to regulate the microstructure of transition metal phosphides,which is helpful for achieving high-performance hydrogen evolution catalysts based on solid-state metal alkoxides.Xupo Liu Shaofeng Deng Peifang Liu Jianing Liang Mingxing Gong Chenglong Lai Yun Lu Tonghui Zhao Deli Wang 2019Science Bulletin2019,64,22:2
13Tiaozhi Tongmai Granules reduce atherogenesis and promote the expression of ATP-binding cassette transporter A1 in rabbit atherosclerotic plaque macrophages and the liver显示文摘Objective:ATP-binding cassette transporter A1(ABCA1)is an integral membrane protein that plays a key role in cellular lipid metabolism,preventing the accumulation of lipids that contribute to the initiation and progression of atherosclerosis.Tiaozhi Tongmai Granules are a Chinese herbal compound that is capable of treating atherosclerosis.This study was designed to explore the potential pharmacological mechanism by which Tiaozhi Tongmai Granules protect against atherosclerosis.Methods:Forty-nine male New Zealand rabbits were randomly divided into seven groups:normal control group,normal diet;model groups 1 and 2:balloon injury and high-fat diet for 6 or 12 weeks;statin groups 1 and 2:balloon injury and high-fat diet plus atorvastatin for 6 or 12 weeks;and Chinese herb groups 1 and 2:balloon injury and high-fat diet plus Tiaozhi Tongmai Granules for 6 or12 weeks.The granules were administered at a dose of 1.14 g/kg/d,with atorvastatin(1.14 mg/kg/d)serving as positive control.Serum lipid profiles and liver function indices were measured.Atherogenesis was viewed after H&E staining and quantified by thickened intimal area percentage and maximal intimal thickness percentage.The ABCA1 protein expression in atherosclerotic plaque macrophages of the common carotid arteries(CCA),thoracic aortae(TA),and liver tissues were observed by immunohistochemical staining and evaluated using mean optical density(OD)value in macrophages and ABCA1-positive hepatocyte number.Results:Compared with model group 1 at week 6,Chinese herb group 1 and statin group 1 displayed significant reductions in total cholesterol(TC)(PZ0.027,0.012)and low-density lipoprotein cholesterol(LDL-C)(PZ0.039,0.028)levels,as well as marked increases in ABCA1-positive hepatocyte numbers(P all<0.001),and only statin group 1 displayed a markedly reducedmaximal intimal thickness percentage in the CCA(P Z 0.018).Compared with model group 2 at week 12,Chinese herb group 2 and statin group 2 all presented significant reductions in TC(P Z 0.011,0.003),LDL-C(P Z 0.017,0.010)and thickened intimal area percentage in the CCA(P Z 0.001,0.022),as well as prominent increases in the ABCA1 OD value of both the CCA(P Z 0.001,0.039)and TA(P Z 0.001,0.025)and positive hepatocyte number(P all<0.001).Chinese herb group 2 had a markedly reduced maximal intimal thickness percentage compared with model group 2(P Z 0.006)and a higher positive hepatocytes number than statin group 2(P Z 0.001).Conclusions:Tiaozhi Tongmai Granules appear to have an anti-atherogenic effect that is most likely mediated by simultaneously upregulating the protein expression of ABCA1 in rabbit atherosclerotic plaque macrophages and in the liver.Qing Sun Lu Zhang Shuwen Guo Min Zheng Dandan Yang Chenglong Zheng Jiani Wu Jian Liu Jingping Wu 2014Journal of Traditional Chinese Medical Sciences2014,1,1:2
14Autophagosome activity in macrophage for atherosclerotic plaques in ApoE^-/-mice enhanced by Tiaozhi Tongmai Granules显示文摘Objective:Atherosclerosis is the fundamental pathophysiologic component of cardiovascular disease,and Tiaozhi Tongmai Granules show great efficiency in the treatment of the disease.However,the mechanism of Tiaozhi Tongmai Granules is still unclear.In this study,we have combined experiments with network pharmacology to explore the antiatherosclerosis mechanism of Tiaozhi Tongmai Granules.Method:120 male ApoE/mice were randomly divided into three groups:the model group,Chinese herb group and Atorvastatin group.The model group,Atorvastatin group and Chinese herb group were fed with a high-fat diet,a high-fat diet plus atorvastatin(5.1 mg/kg/d)and a high-fat diet plus Tiaozhi Tongmai Granules(16.5 g/kg/d)for 16 weeks,respectively.Atherogenesis was identified by H&E staining.The colocalization of neutral lipid stain BODIPY and microtubule-associated protein 1 light chain 3(LC3)and the colocalization of BODIPY and lysosomal-associated membrane protein 1(LAMP1)within ApoE/mice aortic plaques were tested using fluorescence confocal microscopy and the Pearson’s coefficients were calculated.To further explore the anti-atherosclerosis mechanism of Tiaozhi Tongmai Granules,the network pharmacology was used to construct the herb-compound-target network.Results:The size of the aortic lipid plaque in the Chinese herb group and Atorvastatin group were smaller compared with the model group on the 16th week.Compared with the model group on the 16th week,the BODIPY and LC3 colocalization rate,the BODIPY and LAMP1 colocalization rate of the Chinese herb group and Atorvastatin group all presented significant increase in the aortic plaque(P<.001),showing that Tiaozhi Tongmai Granules could enhance autophagosome activity in the macrophage.In the herb-compound-target network,17 active compounds and 27 targets were obtained through literature searching and using LHRI&DAVID Bioinformatics.It was found that 23 targets were correlated with the macrophage.Some of them participated in macrophage inflammatory response,and the other targets could promote/inhibit phagocytosis of the macrophage.It was hypothesized that the active compounds of Tiaozhi Tongmai Granules were acting on these targets and having y the biological effects.Conclusions:In the progression stage of atherosclerosis,Tiaozhi Tongmai Granules can still make the macrophage have higher autophagosome activity,and play a role of anti-atherogenesis.Chenglong Zheng Qing Sun Lu Zhang Shuwen Guo Min Zheng Yan Tang Jiangong Wu Jiani Wu Wenchen Liu Zhaoduo Su Xi Chen 2015Journal of Traditional Chinese Medical Sciences2015,2,3:2
15FORMATION AND EROSION PROCESSES OF THE LOESS PLATEAU显示文摘The uplift of the Tibet Plateau resulted in large-scale Gobi and deserts in Northwest China,in which the fine particles finer than 0.1 mm were transported to and deposited in the region of the Loess Plateau by wind, and then formed the loess of a great thickness. The body of loess deposition can be viewed as a giant lenticular structure named 'Loess mantle'. According to the process of loess deposition, it can be divided into four subregions: the transitional zone, the stable zone, the marginal zone and the long-range zone of loess deposition. Primarily the long-term climatic changes caused the gully erosion in the stable zone. This paper aims to re-establish the stops of the gully development using the geological records of the gully system on the Loess Plateau and to establish the mathematical model of soil erosion. With this mathematical model the natural erosion module has been calculated as 10 250 t/km2.a for the Ausal area of Shaanxi Province. However, the actual erosion module is 15,000 t/km2.a because about 31 .6% of the total erosion is created by human activities.Yuan, Baoyin Lu, Zhongchen Deng, Chenglong 1999International Journal of Sediment Research1999,14,2:2

17A polymer electrolyte with a thermally induced interfacial ion-blocking function enables safety-enhanced lithium metal batteries显示文摘Lithium metal batteries(LMBs)have recently been revitalized as one of the most promising electrochemical energy storage systems,owing to the ultrahigh specific capacity(3860 mAh g^(-1))and ultralow potential(-3.04 V vs.standard hydrogen electrode)of lithium metal anodes.However,safety hazards originating from lithium dendrite growth and pulverization during cycling and thermal stimulation present significant challenges to the practical application of LMBs.To address this issue,we have developed an in situ polymer electrolyte with thermally induced interfacial ion-blocking ability.We demonstrate that the repolymerization and deposition of residual vinylene carbonate in the as-prepared electrolyte under thermal abuse predominantly results in thermally induced ion blocking at the solid electrolyte interface,thus achieving superior LMB safety.The developed polymer electrolyte also yields superior cyclability in LMBs.This design philosophy provides a good paradigm for improving the safety of LMBs.Huanrui Zhang Lang Huang Hantao Xu Xiaohu Zhang Zhou Chen Chenhui Gao Chenglong Lu Zhi Liu Meifang Jiang Guanglei Cui 2022eScience2022,2,2:1
18Crustal deformation and dynamics of Early Cretaceous in the North China Craton显示文摘The Early Cretaceous represents a peak period of the North China Craton(NCC)destruction.A comprehensive analysis of crustal deformation during this period can reveal processes and dynamics of the destruction.The peak destruction of the NCC was associated with intense extension whose representative deformation products are metamorphic core complexes(MCCs),extensional domes and rifted basins.These MCCs occurred along both northern and southern margins of the NCC,and resulted from synchronous extension and magmatism,showing difference from the typical orogen-type MCCs in many aspects.The MCCs of the Early Cretaceous were replaced by extensional domes under relatively weak extension and uplift.In contrast to a major depression-type basin of the Early Cretaceous in the western NCC,rifted basins of the same age in the eastern NCC appeared as medium-to small-scale ones extensively.In the eastern NCC,the rifted basins north of the Bohai Bay are characterized by a feature similar to an active rift whereas those south of the Bohai present similarity to a passive rift.Various sorts of extensional structures developed during the peak destruction indicate a stable stress state of NE-SE extension over the entire central to eastern NCC,consistent with the plate margin-driven stress field.Spatial distribution of the extensional structures presents an 1800 km wide back-arc extension region in the central to eastern NCC,consistent with the Paleo-Pacific slab rollback model following flat subduction.Temporal-spatial variation of initial extension and volcanic activity during the peak period also supports the rollback model right after the flat oceanic slab.The crustal deformation evolution demonstrates that the peak destruction of the NCC took place after the B-episode compression of the Yanshan Movement of the earliest Early Cretaceous and terminated with onset of the C-episode compression of the earliest Late Cretaceous.Guang ZHU Yuanchao LU Nan SU Xiaodong WU Hao YIN Shuai ZHANG Chenglong XIE Manlan NIU 2021Science China Earth Sciences2021,64,9:1
