| 1 | Characteristics of authigenic pyrites in shallow core sediments in the Shenhu area of the northern South China Sea: Implications for a possible mud volcano environment显示文摘Distinct pyrites have been recovered from a shallow sediment core from Site 4B in the Shenhu area of the northern South China Sea. Based on the lithology, texture and structure of sediments, the stable sulfur isotope of pyrite and the total organic carbon (TOC) concentration of the sediments, a distinctive sediment interface is identified at a depth of about 1 m below the seafloor in the core sediments. The pyrites only accumulate in the lower part of the core as rods and foraminifera-infillings, and mainly within three intervals marked by high pyrite concentrations. The amount of pyrite in the sediments shows no remarkable correlation with TOC in the Site 4B core sediments. The stable sulfur isotopes of the pyrite have extremely negative values ranging from 41.69‰ to 49.16‰. They are considered to be the mutual product of sulfate bacterial reduction and sulfur bacterial disproportionation. Our research proposes that Site 4B might be located in or near a possible mud volcano sedimentary environment; a large amount of methane could migrate from deep to shallow sediments in an active mud volcano and thereby play a key role in the intensity of sulfate bacterial reduction and the amount of pyrite formed at Site 4B. Further, the variation in flux of deep methane fluid by intermittent mud volcanic eruptions might result in the deposition of authigenic pyrite intervals. | XIE Lei WANG JiaSheng WU NengYou WU DaiDai WANG Zhou ZHU XiaoWei HU Jun CHEN HongRen LIN Qi | 2013 | Science China Earth Sciences2013，56，4： | 14 |
| 2 | Ultrafast and broadband photodetectors based on a perovskite/organic bulk heterojunction for large-dynamic-range imaging显示文摘Organic-inorganic hybrid perovskite(OIHP)photodetectors that simultaneously achieve an ultrafast response and high sensitivity in the near-infrared(NIR)region are prerequisites for expanding current monitoring,imaging,and optical communication capbilities.Herein,we demonstrate photodetectors constructed by OIHP and an organic bulk heterojunction(BHJ)consisting of a low-bandgap nonfullerene and polymer,which achieve broadband response spectra up to 1μm with a highest external quantum efficiency of approximately 54%at 850 nm,an ultrafast response speed of 5.6 ns and a linear dynamic range(LDR)of 191 dB.High sensitivity,ultrafast speed and a large LDR are preeminent prerequisites for the practical application of photodetectors.Encouragingly,due to the high-dynamicrange imaging capacity,high-quality visible-NIR actual imaging is achieved by employing the OIHP photodetectors.We believe that state-of-the-art OIHP photodetectors can accelerate the translation of solution-processed photodetector applications from the laboratory to the imaging market. | Chenglong Li Hailu Wang Fang Wang Tengfei Li Mengjian Xu Hao Wang Zhen Wang Xiaowei Zhan Weida Hu Liang Shen | 2020 | Light(Science & Applications)2020，9，1： | 13 |
| 3 | Process optimization of neodymium chloride solutions precipitated by magnesium bicarbonate显示文摘Rare earths(REs) are of vital importance for the development of new materials and green energy.Magnesium bicarbonate is one of the most recyclable and environmental-friendly precipitant for REs recovery from leaching solutions. Nd_2(CO_3)_3 has difficulties in industrial production. So in this study,the precipitation of neodymium from chloride solution by magnesium bicarbonate are investigated. The effects of feeding method, [HCO_3^-]/[Nd^(3+)] mole ratio, feeding speed and reaction temperature on yield and impurity(magnesia) content are systematically studied. Results show that the impurity(magnesia)content decreases to 0.010 wt% with a yield approaching to 100% obtained under the conditions of[HCO_3^-]/[Nd^(3+)] = 3.00 by parallel flow addition at 50 ℃. The major impurity(magnesia) in rare earth carbonates mainly presents in the form of physical absorption, which can be easily removed by scrubbing. Therefore, it offers a promising green process that uses magnesium bicarbonate to produce neodymium carbonate due to its cycling of carbon dioxide, magnesium salt and waste water. | Yannan Yan Yang Xu Xiaowei Huang Zongyu Feng Yongke Hou Kai Li Liangshi Wang Yihanna Hu | 2019 | Journal of Rare Earths2019，37，4： | 10 |
| 4 | 1,25-Dihydroxyvitamin D3 protects obese rats from metabolic syndrome via promoting regulatory T cell-mediated resolution of inflammation显示文摘Vitamin D_3 has been found to produce therapeutic effects on obesity-associated insulin resistance and dyslipidemia through its potent anti-inflammatory activity, but the precise immunomodulatory mechanism remains poorly understood. In the present study we found that 1,25-dihydroxyvitamin D_3[1,25(OH)_2D_3], the biologically active form of vitamin D_3, significantly attenuated monosodium glutamate(MSG)-induced obesity and insulin resistance as indicated by body weight reduction, oral glucose tolerance improvement, and a glucose infusion rate increase as detected with hyperinsulinemiceuglycemic clamp. Moreover, 1,25(OH)_2D_3 not only restored pancreatic islet functions but also improved lipid metabolism in insulin-targeted tissues. The protective effects of 1,25(OH)_2D_3 on glycolipid metabolism were attributed to its ability to inhibit an obesity-activated inflammatory response in insulin secretory and targeted tissues, as indicated by reduced infiltration of macrophages in pancreas islets and adipose tissue while enhancing the expression of Tgf-β1 in liver tissue, which was accompanied byincreased infiltration of Treg cells in immune organs such as spleen and lymph node as well as in insulintargeted tissues such as liver, adipose, and muscle. Together, our findings suggest that 1,25(OH)_2D_3 serves as a beneficial immunomodulator for the prevention and treatment of obesity or metabolic syndrome through its anti-inflammatory effects. | Wen Jin Bing Cui Pingping Li Fang Hua Xiaoxi Lv Jichao Zhou Zhuowei Hu Xiaowei Zhang | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 9 |

| 6 | Decomposition behavior of CaSO_4 during potassium extraction from a potash feldspar-CaSO_4 binary system by calcination显示文摘The extraction of potassium from a tablet mixture of K-feldspar ore and CaSO_4by roasting was studied with a focus on the effects of the decomposition behavior of CaSO_4on the potassium extraction process.The roasted slags were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy,and thermogravimetric(TG)analysis.The XRD analysis revealed that hydrosoluble mischcrystal K_2Ca_2(SO_4)_3was obtained by ion exchange of Ca^(2+)in CaSO_4and K^+in KAlSi_3O_8.Meanwhile,the intermediate product,SiO_2,separated from KAl Si_3O_8and reacted with CaSO_4to decompose CaSO_4.The SEM results showed that some blowholes emerged on the surface of the CaSO_4particles when they reacted with SiO_2at 1200°C,which indicates that SO_2and O_2gases were released from CaSO_4.The TG curves displayed that pure CaSO_4could not be decomposed below 1200°C,while the mixture of K-feldspar ore and CaSO_4began to lose weight at 1000°C.The extraction rate of potassium and decomposition rate of CaSO_4were 62%and 44%,respectively,at a mass ratio of CaSO_4to K-feldspar ore of 3:1,temperature of 1200°C,tablet-forming pressure of6 MPa,and roasting time of 2 h.The decomposition of CaSO_4reduced the potassium extraction rate;therefore,the required amount of CaSO_4was more than the theoretical amount.However,excess CaSO_4was also undesirable for the potassium extraction reaction because a massive amount of SO_2and O_2gas were derived from the decomposition of CaSO_4,which provided poor contact between the reactants.The SO_2released from CaSO_4decomposition can be effectively recycled. | Li Lü Chun Li Guoquan Zhang Xiaowei Hu Bin Liang | 2018 | Chinese Journal of Chemical Engineering2018，26，4： | 7 |
| 7 | Atg5 regulates late endosome and lysosome biogenesis显示文摘Autophagy is an evolutionarily conserved lysosome-based degradation process.Atg5 plays a very important role in autophagosome formation.Here we show that Atg5 is required for biogenesis of late endosomes and lysosomes in an autophagy-independent manner.In Atg5 cells,but not in other essential autophagy genes defecting cells,recycling and retrieval of late endosomal components from hybrid organelles are impaired,causing persistent hybrid organelles and defective formation of late endosomes and lysosomes.Defective retrieval of late endosomal components from hybrid organelles resulting from impaired recruitment of a component of V1-ATPase to acidic organelles blocks the pH-dependent retrieval of late endosomal components from hybrid organelles.Lowering the intracellular pH restores late endosome/lysosome biogenesis in Atg5 cells.Our data demonstrate an unexpected role of Atg5 and shed new light on late endosome and lysosome biogenesis. | PENG JunYa ZHANG Ran CUI YiTong LIU HaoDong ZHAO XiaoXin HUANG Lei HU MingXu YUAN XiaoXi MA BenYu MA XiaoWei TAKASHI Ueno MASAAKI Komatsu LIANG XingJie YU Li | 2014 | Science China(Life Sciences)2014，57，1： | 6 |
| 8 | Global analysis of CCT family knockout mutants identifies four genes involved in regulating heading date in rice显示文摘Many genes encoding CCT domain-containing proteins regulate flowering time. In rice(Oryza sativa), 41 such genes have been identified, but only a few have been shown to regulate heading date. Here, to test whether and how additional CCT family genes regulate heading date in rice, we classified these genes into five groups based on their diurnal expression patterns. The expression patterns of genes in the same subfamily or in close phylogenetic clades tended to be similar. We generated knockout mutants of the entire gene family via CRISPR/Cas9. The heading dates of knockout mutants of only 4 of 14 genes previously shown to regulate heading date were altered, pointing to functional redundancy of CCT family genes in regulating this trait. Analysis of mutants of four other genes showed that OsCCT22, OsCCT38, and OsCCT41 suppress heading under long-day conditions and promote heading under short-day conditions. OsCCT03 promotes heading under both conditions and upregulates the expression of Hd1 and Ehd1, a phenomenon not previously reported for other such genes. To date, at least 18 CCT domaincontaining genes involved in regulating heading have been identified, providing diverse, flexible gene combinations for generating rice varieties with a given heading date. | Jia Zhang Xiaowei Fan Yong Hu Xiangchun Zhou Qin He Liwen Liang Yongzhong Xing | 2021 | Journal of Integrative Plant Biology2021，63，5： | 6 |
| 9 | Post-Orogenic Tectonic Evolution of the Jiangnan-Xuefeng Orogenic Belt:Insights from Multiple Geochronometric Dating of the Mufushan Massif,South China显示文摘The Mufushan massif, as continental intra-plate magmatites located in the Jiangnan-Xuefeng orogenic belt of the South China. The Mufushan massif constitutes the largest Mesozoic intrusive complex, intruded the Mesoproterozoic Lengjiaxi Formation. Multiple geochronometric dating was used to reconstruct their evolution from emplacement to exhumation. The Mufushan granitoids were emplaced at ~150 Ma(U-Pb zircon) as post-orogenic magmatites contributing to Triassic crustal thickening. Onset of regional extension at ~128 Ma(40Ar/39Ar white mica and biotite) manifests a tectonic regime switch. Intense exhumation prior to ~55 Ma was followed by slow denudation and peneplanation for the next 37 Ma(~55–18 Ma). Accelerated cooling since ~18 Ma may have been caused by a far-field effect of the collision between IndiaAsia Plate or the Pacific-Plate subduction. Through a multi-geochronometric approach, this study provides a new comprehensive model for the cause of the intra-plate magmatism formation in the South China, and also established a reliable geochronological framework of the post-orogenic tectonic evolutions of the Jiangnan-Xuefeng orogenic belt. | Chuanbo Shen Di Hu Kyoungwon Min Chaoqun Yang Xiaowei Zeng Hongyang Fu Xiang Ge | 2020 | Journal of Earth Science2020，31，5： | 4 |
| 10 | Extraction kinetics of neodymium from chloride medium using HEH/EHP saponified with magnesium bicarbonate solution显示文摘Magnesium bicarbonate solution is considered as an environmentally friendly extractant saponification agent for the solvent extraction of rare earth elements due to its advantage of minimum water pollution.In order to reveal the extraction regularity, optimize production-process and guide the use of this new extraction system, the extraction of Nd(Ⅲ) in chloride medium with HEH/EHP saponified by magnesium bicarbonate solution was investigated with the self-designed constant interfacial area cell. Besides, the effects of stirring rate, temperature, specific interfacial area and concentration of Mg-HEH/EHP on the extraction rate of Nd(Ⅲ) were systematically investigated. Results show that, the rate of extraction is governed by both diffusion and chemical reaction, and the extraction reaction takes place at the interface. The apparent activation energy of the extraction reaction is 16.88 kJ/mol. The corresponding rate equation is deduced. The mechanisms and rate-determining step are speculated based on interfacial reaction models, which is consistent with the experimental results. | Hao Lv Xiaowei Huang Zongyu Feng Meng Wang Xu Sun Xinlin Peng Dali Cui Yihanna Hu | 2019 | Journal of Rare Earths2019，37，3： | 4 |
| 11 | Recovery of rare earths and aluminum from FCC waste slag by acid leaching and selective precipitation显示文摘This paper investigated the recovery of rare earth elements(REEs) and aluminum(AI) from the waste slag discharged by FCC catalyst factory(FCC waste slag) via acid leaching and selective precipitation.Analysis methods such as ICP-AES, XRF and XRD were applied to obtain experiment data. The maximum leaching efficiency of REEs and Al was achieved at pH value of 1 and with liquid to solid ratio of 4:1,Under such conditions, 91.01%, 92.24% and 94.77% of La, Ce and Al were extracted at 20 ℃ for 2 h from the FCC waste slag, respectively. The SiO_2 content in the leaching residue was 88.3%, which can be used as an available silicon resource. The REEs can be precipitated in the form of REEs and sodium double sulfate(NaRE(SO_4)_2·xH_2 O) by adding Na_2 SO_4 to the leaching solution, while Al remained in the solution. Afterwards, the pH value of the filtrate was adjusted to 4.5, and Al was precipitated as AI(OH)_3. Finally,NaRE(SO_4)_2·xH_2 O and Al(OH)_3 were converted into RECl_3 and Al_2(SO4)_3 solution,respectively, which were recycled to manufacture zeolite. This process recovered REEs and Al from the FCC waste slag and reduced the emissions of waste slag simultaneously, which has an important economic and environment significance. | Jinyu wang Xiaowei Huang Dali Cui Liangshi Wang Zongyu Feng Bin Hu Zhiqi Long Na Zhao | 2017 | Journal of Rare Earths2017，35，11： | 4 |
| 12 | Luminescence modification of Eu3+-activated molybdate phosphor prepared via co-precipitation显示文摘Eu-activated CaMoO4 phosphors were co-precipitated in an aqueous solution, and NH3·H2O, NH4HCO3 and (NH2)2CO as pre-cipitating aid agents were compared based on the morphology and particle size distribution of the phosphor samples. Sm3+ as sensitizer ion was investigated on the luminescence of CaMoO4:Eu, and it could strengthen the 406 nm absorption of this phosphor. At last, the scheelite CaMoO4:Eu and wolframite ZnMoO4:Eu were selected to compare their host absorption. The result showed that the scheelite molybdate host exhibited stronger UV absorption than wolframite one. | ZHAO Chunlei HU Yunsheng ZHUANG Weidong HUANG Xiaowei HE Tao | 2009 | Journal of Rare Earths2009，27，5： | 4 |

| 14 | COPII mitigates ER stress by promoting formation of ER whorls显示文摘Cells mitigate ER stress through the unfolded protein response(UPR).Here,we report formation of ER whorls as an effector mechanism of the ER stress response.We found that strong ER stress induces formation of ER whorls,which contain ER-resident proteins such as the Sec61 complex and PKR-like ER kinase(PERK).ER whorl formation is dependent on PERK kinase activity and is mediated by COPII machinery,which facilitates ER membrane budding to form tubular-vesicular ER whorl precursors.ER whorl precursors then go through Sec22b-mediated fusion to form ER whorls.We further show that ER whorls contribute to ER stressinduced translational inhibition by possibly modulating PERK activity and by sequestering translocons in a ribosome-free environment.We propose that formation of ER whorls reflects a new type of ER stress response that controls inhibition of protein translation. | Fang Xu Wanqing Du Qin Zou Yuting Wang Xin Zhang Xudong Xing Ying Li Dachuan Zhang Huimin Wang Wenhao Zhang Xinyao Hu Xin Liu Xiaoling Liu Shaojin Zhang Jinqiang Yu Jianhuo Fang Fajin Li Ying Zhou Tieqiang Yue Na Mi Haiteng Deng Peng Zou Xiaowei Chen Xuerui Yang Li Yu | 2021 | Cell Research2021，31，2： | 4 |
| 15 | Antagonism of toll-like receptor 2 attenuates the formation and progression of abdominal aortic aneurysm显示文摘Abdominal aortic aneurysm(AAA) is an inflammatory vascular disorder with high mortality.Accumulating evidence shows that toll-like receptor 2(TLR2) plays a critical role in the regulation of wound-repairing process after tissue injury.We wondered if TLR2 signaling contributed to the pathogenesis of AAA and that targeting TLR2 would attenuate AAA development and progression.In this study,enhanced expression of TLR2 and its ligands were observed in human AAA tissue.Neutralization of TLR2 protected against AAA development and caused established AAA to regress in mouse models of AAA.In addition,TLR2-deficient mice also failed to develop AAA.The prophylactic and therapeutic effects of blocking TLR2 were accompanied by a significant resolution of inflammation and vascular remodeling,as indicated by the decreased expression or activity of MMP-2/9,α-SMA,inflammatory cytokines,and transcription factors NF-κB,AP-1 and STAT1/3 in AAA tissue.Mechanistically,blocking TLR2 decreased the expression and interaction of TLR2 and several endogenousligands,which diminished chronic inflammation and vascular remodeling in the vascular tissue of AAA.Our studies indicate that the interactions between TLR2 and its endogenous ligands contribute to the pathogenesis of AAA and that targeting TLR2 offers great potential toward the development of therapeutic agents against AAA. | Huimin Yan Bing Cui Xiaowei Zhang Xiaoming Fu Jun Yan Xiaoxing Wang Xiaoxi Lv Zhong Chen Zhuowei Hu | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 3 |
| 16 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |

| 18 | Auxin response factor 6A regulates photosynthesis,sugar accumulation,and fruit development in tomato显示文摘Auxin response factors(ARFs)are involved in auxin-mediated transcriptional regulation in plants.In this study,we performed functional characterization of SlARF6A in tomato.SlARF6A is located in the nucleus and exhibits transcriptional activator activity.Overexpression of SlARF6A increased chlorophyll contents in the fruits and leaves of tomato plants,whereas downregulation of SlARF6A decreased chlorophyll contents compared with those of wild-type(WT)plants.Analysis of chloroplasts using transmission electron microscopy indicated increased sizes of chloroplasts in SlARF6A-overexpressing plants and decreased numbers of chloroplasts in SlARF6A-downregulated plants.Overexpression of SlARF6A increased the photosynthesis rate and accumulation of starch and soluble sugars,whereas knockdown of SlARF6A resulted in opposite phenotypes in tomato leaves and fruits.RNA-sequence analysis showed that regulation of SlARF6A expression altered the expression of genes involved in chlorophyll metabolism,photosynthesis and sugar metabolism.SlARF6A directly bound to the promoters of SlGLK1,CAB,and RbcS genes and positively regulated the expression of these genes.Overexpression of SlARF6A also inhibited fruit ripening and ethylene production,whereas downregulation of SlARF6A increased fruit ripening and ethylene production.SlARF6A directly bound to the SAMS1 promoter and negatively regulated SAMS1 expression.Taken together,these results expand our understanding of ARFs with regard to photosynthesis,sugar accumulation and fruit development and provide a potential target for genetic engineering to improve fruit nutrition in horticulture crops. | Yujin Yuan Xin Xu Zehao Gong Yuwei Tang Mengbo Wu Fang Yan Xiaolan Zhang Qian Zhang Fengqing Yang Xiaowei Hu Qichen Yang Yingqing Luo Lihua Mei Wenfa Zhang Cai-Zhong Jiang Wangjin Lu Zhengguo Li Wei Deng | 2019 | Horticulture Research2019，6，1： | 3 |
| 19 | Multi-interface collaboration of graphene cross-linked NiS-NiS_(2)-Ni_(3)S_(4) polymorph foam towards robust hydrogen evolution in alkaline electrolyte显示文摘Electrocatalytic hydrogen production in alkaline media is extensively adopted in industry. Unfortunately, further performance improvement is severely impeded by the retarded kinetics, which requires the fine regulation of water dissociation, hydrogen recombination, and hydroxyl desorption. Herein, we develop a multi-interface engineering strategy to make an elaborate balance for the alkaline hydrogen evolution reaction (HER) kinetics. The graphene cross-linked three-phase nickel sulfide (NiS-NiS_(2)-Ni_(3)S_(4)) polymorph foam (G-NNNF) was constructed through hydrothermal sulfidation of graphene wrapped nickel foam as a three-dimensional (3D) scaffold template. The G-NNNF exhibits superior catalytic activity toward HER in alkaline electrolyte, which only requires an overpotential of 68 mV to drive 10 mA·cm^(−2) and is better than most of the recently reported metal sulfides catalysts. Density functional theory (DFT) calculations verify the interfaces between nickel sulfides (NiS/NiS_(2)-Ni_(3)S_(4)) and cross-linked graphene can endow the electrocatalyst with preferable hydrogen adsorption as well as metallic nature. In addition, the electron transfer from Ni_(3)S_(4)/NiS_(2) to NiS results in the electron accumulation on NiS and the hole accumulation on Ni_(3)S_(4)/NiS_(2), respectively. The electron accumulation on NiS favors the optimization of the H* adsorption, whereas the hole accumulation on Ni_(3)S_(4) is beneficial for the adsorption of H_(2)O. The work about multi-interface collaboration pushes forward the frontier of excellent polymorph catalysts design. | Haiqing Wang Wenjing Zhang Xiaowei Zhang Shuxian Hu Zhicheng Zhang Weijia Zhou Hong Liu | 2021 | Nano Research2021，14，12： | 3 |
| 20 | Designing of multifunctional and flame retardant separator towards safer high-performance lithium-sulfur batteries显示文摘Owing to unprecedented merits such as high theoretical capacity,superior energy density and low cost,lithium-sulfur batteries(LSBs)show a bright future both in scientific and industrial areas.Whereas,the inherent issues,including highly insulating character,undesired shuttle behavior and lithium dendrites growth,are seriously impeding its practical usage.Here,a metal-organic-frameworks(MOFs)derived N,S co-doped carbon nanotube hollow architecture confining with CoS_(2) nanoparticles(CoS_(2)/NSCNHF)modified separator is designed to surmount these obstacles.Compared with Celgard separator,this designed separator shows obviously enhanced flame retardancy,giving 73.1%and 53.0%reductions in peak heat release rate and total heat release,separately.Concretely,its hollow structure,conductive feature,electrocatalytic activity and Lewis acid-base interaction enable the efficient inhibition on shuttle behavior as well as boost in polysulfides conversion kinetics.The cell with modified separator delivers a high discharge capacity of 1,284.5 mAh·g^(−1).After running for 100 cycles,a discharge capacity of 661.3 mAh·g^(−1) is remained.Markedly,the suppression on lithium dendrites growth is also observed,manifesting the enhanced battery safety.Overall,this work may shed light on the effective usage of MOFs-derived hierarchical composite in achieving LSBs with high electrochemical performance as well as safety. | Junling Wang Wei Cai Xiaowei Mu Longfei Han Na Wu Can Liao Yongchun Kan Yuan Hu | 2021 | Nano Research2021，14，12： | 3 |
