1Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed.Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao 2018Stroke & Vascular Neurology2018,3,3:29
2Principles and methods for the validation of quantitative remote sensing products显示文摘We first discuss the relativity of 'true value and homogeneity' for quantitative remote sensing products (QRSPs), and then propose the definitions of 'eigenaccuracy' and 'eigenhomogeneity' under practical conditions. The eigenaccuracy and eigenhomogeneity for land surface crucial parameters such as albedo, leaf area index (LAI), and surface temperature are analyzed based on a series of experiments. Secondly, we point out the differences and similarities between the scale-free phenomena of the QRSPs and the measurements of the coastline length (1-dimensional) and the curved surface area (2-dimensional). An information fractal algorithm for the QRSPs is presented. In a case study for the LAI, when the fractal dimension is 2.16, the ratio of the LAI retrieval values obtained respectively from remote sensing data of 30 m and 6 km pixel resolution can actually reach as high as 2.86 for the same 6 km pixel using the same retrieval model. Finally, we propose an operational validation method 'one test and two matches' and multipoint observation when the real situation does not allow carrying out scanning measurement without gap and overlap on the ground surface.RenHua Zhang Jing Tian ZhaoLiang Li HongBo Su ShaoHui Chen XinZhai Tang 2010Science China Earth Sciences2010,53,5:27
3The Chrysanthemum nankingense Genome Provides Insights into the Evolution and Diversification of Chrysanthemum Flowers and Medicinal Traits显示文摘The Asteraceae (Compositae),a large plant family of approximately 24 000-35 000 species,accounts for^10% of all angiosperm species and contributes a lot to plant diversity.The most representative members of the Asteraceae are the economically important chrysanthemums (Chrysanthemum L.)that diversified through reticulate evolution.Biodiversity is typically created by multiple evolutionary mechanisms such as wholegenome duplication 0NGD)or polyploidization and locally repetitive genome expansion.However,the lack of genomic data from chrysanthemum species has prevented an in-depth analysis of the evolutionary mechanisms involved in their diversification.Here,we used Oxford Nanopore long-read technologyto sequence the diploid Chrysanthemum nankingense genome,which represents one of the progenitor genomes of domesticated chrysanthemums.Our analysis revealed that the evolution of the C.nankingense genome was driven by bursts of repetitive element expansion and WGD events including a recentWGD that distinguishes chrysanthemum from sunflower,which diverged from chrysanthemum approximately 38.8 million years ago.Variations of ornamental and medicinal traits in chrysanthemums are linked to the expansion of candidate gene families by duplication events including paralogous gene duplication.Collectively,our study of the assembled reference genome offers new knowledge and resources to dissect the history and pattern of evolution and diversification of chrysanthemum plants,and also to accelerate their breeding and improvement.Chi Song Yifei Liu Aiping Song Gangqiang Dong Hongbo Zhao Wei Sun Shyam Ramakrishnan Ying Wang Shuaibin Wang Tingzhao Li Yan Niu Jiafu Jiang Bin Dong Ye Xia Sumei Chen Zhigang Hu Fadi Chen Shilin Chen 2018Molecular Plant2018,11,12:24
4Observation and analysis of atmospheric volatile organic compounds in a typical petrochemical area in Yangtze River Delta, China显示文摘Volatile organic compounds(VOCs) are a kind of important precursors for ozone photochemical formation. In this study, VOCs were measured from November 5 th, 2013 to January 6 th, 2014 at the Second Jinshan Industrial Area, Shanghai, China. The results showed that the measured VOCs were dominated by alkanes(41.8%), followed by aromatics(20.1%), alkenes(17.9%), and halo-hydrocarbons(12.5%). The daily trend of the VOC concentration showed a bimodal feature due to the rush-hour traffic in the morning and at nightfall. Based on the VOC concentration, a receptor model of Positive Matrix Factorization(PMF) coupled with the information related to VOC sources was applied to identify the major VOC emissions. The result showed five major VOC sources: solvent use and industrial processes were responsible for about 30% of the ambient VOCs, followed by rubber chemical industrial emissions(23%), refinery and petrochemical industrial emissions(21%), fuel evaporations(13%) and vehicular emissions(13%). The contribution of generalized industrial emissions was about 74% and significantly higher than that made by vehicle exhaust. Using a propylene-equivalent method, alkenes displayed the highest concentration, followed by aromatics and alkanes. Based on a maximum incremental reactivity(MIR)method, the average hourly ozone formation potential(OFP) of VOCs is 220.49 ppbv. The most significant source for ozone chemical formation was identified to be rubber chemical industrial emissions, following one by vehicular emission. The data shown herein may provide useful information to develop effective VOC pollution control strategies in industrialized area.Yunchen Zhang Rui Li Hongbo Fu Dong Zhou Jianmin Chen 2018Journal of Environmental Sciences2018,30,9:21
5Ferroptosis is essential for diabetic cardiomyopathy and is prevented by sulforaphane via AMPK/NRF2 pathways显示文摘Herein,we define the role of ferroptosis in the pathogenesis of diabetic cardiomyopathy(DCM)by examining the expression of key regulators of ferroptosis in mice with DCM and a new ex vivo DCM model.Advanced glycation end-products(AGEs),an important pathogenic factor of DCM,were found to induce ferroptosis in engineered cardiac tissues(ECTs),as reflected through increased levels of Ptgs2 and lipid peroxides and decreased ferritin and SLC7 A11 levels.Typical morphological changes of ferroptosis in cardiomyocytes were observed using transmission electron microscopy.Inhibition of ferroptosis with ferrostatin-1 and deferoxamine prevented AGE-induced ECT remodeling and dysfunction.Ferroptosis was also evidenced in the heart of type 2 diabetic mice with DCM.Inhibition of ferroptosis by liproxstatin-1 prevented the development of diastolic dysfunction at 3 months after the onset of diabetes.Nuclear factor erythroid 2-related factor 2(NRF2)activated by sulforaphane inhibited cardiac cell ferroptosis in both AGE-treated ECTs and hearts of DCM mice by upregulating ferritin and SLC7 A11 levels.The protective effect of sulforaphane on ferroptosis was AMP-activated protein kinase(AMPK)-dependent.These findings suggest that ferroptosis plays an essential role in the pathogenesis of DCM;sulforaphane prevents ferroptosis and associated pathogenesis via AMPK-mediated NRF2 activation.This suggests a feasible therapeutic approach with sulforaphane to clinically prevent ferroptosis and DCM.Xiang Wang Xinxin Chen Wenqian Zhou Hongbo Men Terigen Bao Yike Sun Quanwei Wang Yi Tan Bradley B.Keller Qian Tong Yang Zheng Lu Cai 2022Acta Pharmaceutica Sinica B2022,12,2:20

7Bio-leaching effects of Leptospirillum ferriphilum on the surface chemical properties of pyrite显示文摘Leptospirillum ferriphilum cultured using different energy sources(either soluble ferrous ion or pyrite) changed the surface properties of pyrite.Cell adsorption,zeta-potential,hydrophobicty,FT-IR spectra and surface morphology were investigated.Adhesion of bacterial cells to the pyrite surface is a fast process.Furthermore,the adsorption of cells grown in pyrite is greater than of cells grown in soluble ferrous ion.The Iso-Electric Point(IEP) of pyrite treated with L.ferriphilum approaches that of the cells themselves.The contact angle of the pyrite surface was observed to decrease due to the surface formation of some hydrophilic substances during bio-leaching.Changes in pyrite surface properties after bacterial treatment support the idea that ferric ion plays an important role and that indirect bio-oxidation is the principal mechanism of pyrite bio-leaching.GU, Guohua SU, Lijun CHEN, Minglian SUN, Xiaojun ZHOU, Hongbo 2010Mining Science and Technology2010,20,2:14
8The crucial roles of Th17-related cytokines/signal pathways in M. tuberculosis infection显示文摘Interleukin-17(IL-17),IL-21,IL-22 and IL-23 can be grouped as T helper 17(Th17)-related cytokines because they are either produced by Th17/Th22 cells or involved in their development.Here,we review Th17-related cytokines/Th17-like cells,networks/signals and their roles in immune responses or immunity against Mycobacterium tuberculosis(Mtb)infection.Published studies suggest that Th17-related cytokine pathways may be manipulated by Mtb microorganisms for their survival benefits in primary tuberculosis(TB).In addition,there is evidence that immune responses of the signal transducer and activator of transcription 3(STAT3)signal pathway and Th17-like T-cell subsets are dysregulated or destroyed in patients with TB.Furthermore,Mtb infection can impact upstream cytokines in the STAT3 pathway of Th17-like responses.Based on these findings,we discuss the need for future studies and the rationale for targeting Th17-related cytokines/signals as a potential adjunctive treatment.Hongbo Shen Zheng W Chen 2018Cellular & Molecular Immunology2018,15,3:13
9Identification of the surgical indication line for the Denonvilliers’fascia and its anatomy in patients with rectal cancer显示文摘Background:The high rate of urogenital dysfunction after traditional total mesorectal excision(TME)has caused doubts among scholars on the standard fashion of dissection.We have proposed the necessity to preserve the Denonvilliers’fascia in patients with rectal cancer.However,how to accurately locate the Denonvilliers’fascia is unclear.This study aimed to explore anatomical features of the Denonvilliers’fascia by comparing autopsy findings and observations of surgical videos so as to propose a dissection method for the preservation of pelvic autonomic nerves during rectal cancer surgery.Methods:Five adult male cadaver specimens were dissected,and surgical videos of 135 patients who underwent TME for mid-low rectal cancer between January 2009 and February 2019 were reviewed to identify and compare the structure of the Denonvilliers’fascia.Results:The monolayer structure of the Denonvilliers’fascia was observed in 5 male cadaver specimens,and it was located between the rectum,the bottom of the bladder,the seminal vesicles,the vas deferens,and the prostate.The Denonvilliers’fascia was originated from the rectovesical pouch(or rectum-uterus pouch),down to fuse caudally with the rectourethral muscle at the apex of the prostate,and fused to the lateral ligaments on both sides.The fascia was thinner on the midline with a thickness of 1.06±0.10 mm.The crown shape of the Denonvilliers’fascia was slightly triangular,with a height of approximately 5.42±0.16 cm at midline.Nerves were more densely distributed in front of the Denonvilliers’fascia than behind,especially on both sides of it.Under laparoscopic view,the Denonvilliers’fascia was originated at the lowest point of the rectovesical pouch(or rectum-uterus pouch),with a thickened white line which was a good mark for identifying the Denonvilliers’fascia.Conclusion:Identification of the surgical indication line for the Denonvilliers’fascia could help us identify the Denonvilliers’fascia,and it would improve our ability to protect the pelvic autonomic function of patients undergoing TME for rectal cancer.Jianglong Huang Jing Liu Jiafeng Fang Zongheng Zeng Bo Wei Tufeng Chen Hongbo Wei 2020Cancer Communications2020,40,1:10
10Observations of atmospheric pollutants at Lhasa during 2014-2015:Pollution status and the influence of meteorological factors显示文摘Atmospheric pollutants including SO_2, NO_2, CO, O_3 and inhalable particulate matter(PM2.5 and PM10) were monitored continuously from March 2014 to February 2015 to investigate characteristics of air pollution at Lhasa, Tibetan Plateau. Species exhibited similar seasonal variations except O_3, with the peaks in winter but low valleys in summer. The maximum O_3 concentration was observed in spring, followed by summer, autumn, and winter. The positive correlation between O_3 and PM10 in spring indicated similar sources of them, and was assumed to be turbulent transport. Temperature was the dominant meteorological factor for most species in spring. High temperature accelerates O_3 photochemistry, and favors air disturbance which is conductive to dust resuspension in spring. Relative humidity(RH) and atmospheric pressure were the main meteorological factors in summer. RH showed negative correlations with species, while atmospheric pressure posed opposite situation. Wind speed(WS) was the dominant meteorological factor in autumn, the negative correlations between WS and species indicated diffusion by wind. Most species showed non-significant correlations with meteorological factors in winter, indicating the dependence of pollution on source emission rather than restriction by meteorology. Pollution weather character indicated that emissions were from biomass burning and dust suspension, and meteorological factors also played an important role. Air stream injection from the stratosphere was observed during O_3 pollution period. Air parcels from Southwest Asia were observed during air pollution period in winter. An enhancement in air pollutants such as O_3 would be expected in the future, more attention should be given to countermeasures for prevention of air pollution in the future.Bu Duo Lulu Cui Zhenzhen Wang Rui Li Liwu Zhang Hongbo Fu Jianmin Chen Huifang Zhang A.Qiong 2018Journal of Environmental Sciences2018,30,1:9
11Recent advances in designing conductive hydrogels for flexible electronics显示文摘Flexible electronics have emerged as an exciting research area in recent years,serving as ideal interfaces bridging biological systems and conventional electronic devices.Flexible electronics can not only collect physiological signals for human health monitoring but also enrich our daily life with multifunctional smart materials and devices.Conductive hydrogels(CHs)have become promising candidates for the fabrication of flexible electronics owing to their biocompatibility,adjustable mechanical flexibility,good conductivity,and multiple stimuli-responsive properties.To achieve on-demand mechanical properties such as stretchability,compressibility,and elasticity,the rational design of polymer networks via modulating chemical and physical intermolecular interactions is required.Moreover,the type of conductive components(eg,electron-conductive materials,ions)and the incorporation method also play an important role in the conductivity of CHs.Electron-CHs usually possess excellent conductivity,while ion-CHs are generally transparent and can generate ion gradients within the hydrogel matrices.This mini review focuses on the recent advances in the design of CHs,introducing various design strategies for electron-CHs and ion-CHs employed in flexible electronics and highlighting their versatile applications such as biosensors,batteries,supercapacitors,nanogenerators,actuators,touch panels,and displays.Qiongyao Peng Jingsi Chen Tao Wang Xuwen Peng Jifang Liu Xiaogang Wang Jianmei Wang Hongbo Zeng 2020InfoMat2020,2,5:8
12A lentiviral vector-based therapeutic vaccine encoding Ag85B-Rv3425 potently increases resistance to acute tuberculosis infection in mice显示文摘为 multidrug 抵抗的肺结核(TB ) 和到为 TB 的新奇治疗学的途径的发展的广泛地药抵抗的 TB 电话注意的很少处理选择。因为他们能导致抗原特定的细胞的有免疫力的回答,治疗学的疫苗正在答应候选人,它在 Mycobacterium 肺结核(鱼雷快艇) 的消除起一个重要作用。在这研究,新奇 lentiviral 向量为交付鱼雷快艇特定的熔化蛋白质 Ag85B-Rv3425 的治疗学的疫苗被构造。结果证明这支 recombinant lentivirus 疫苗单个注射的能在老鼠触发抗原特定的 Th1 类型有免疫力的回答。更重要地,有急性感染的老鼠在肺和脾由显著地减少的鱼雷快艇负担从这支疫苗的一个单个剂量的政府有益于很多以及与未经治疗的老鼠相比在肺稀释了损害。这些结果为 TB 的免疫疗法显示了这支新奇疫苗的好前景。Enzhuo Yang Feifei Wang Ying Xu Honghai Wang Yong Hu Hongbo Shen Zheng W.

13Oxyvanite V3O5:A new intercalation-type anode for lithium-ion battery显示文摘In the present study,V3O5 microcrystals that synthesized via vacuum calcination are employed as anodes for lithium-ion batteries(LIBs)for the first time.Despite the widely observed sluggish reaction kinetics and poor cycling stability in most microsized transition metal oxides,the V3O5 microcrystals exhibit excellent rate capability(specific capacities of 144 and 125 mAh g^−1 are achieved at extremely high current densities of 20 and 50 A g^−1,respectively)and long-term cycling performance(specific capacity of 117 mAh g^−1 is sustained over 2000 cycles at 50 A g^−1).It is ascribed to the three-dimensional open-framework structure of the V3O5 microcrystals as a major factor in dictating the fast reaction kinetics(lithium diffusion coefficient:~10−9 cm^2 s^−1).In addition,significant insight into the reaction mechanism of the V3O5 microcrystals in concomitant its phase evolution are obtained from ex-situ XRD study,revealing that the V3O5 microcrystals undergo intercalation reaction with insignificant structural change in response to lithiation/delithiation.Dong Chen Huiteng Tan Xianhong Rui Qi Zhang Yuezhan Feng Hongbo Geng Chengchao Li Shaoming Huang Yan Yu 2019InfoMat2019,1,2:6
14Palaeoenvironmental implication of the Plio-Pleistocene loess deposits in southern Tarim Basin显示文摘The sedimentary characteristics, grain-size distribution, geochemical composition and surface characteristics of quartz grains, together with palaeoenvironmental reconnaissance, all point to an aeolian origin for the intercalated siltstone beds in the Plio-Pleistocene Artux and Xiyu Formations along the southern margins of the Tarim Basin, indicating that loess deposition in the region started, at least, in the Early Pliocene. Loess deposition in the southern Tarim Basin was a response to the global deterioration, which might be attributed to the uplift of the Tibetan Plateau.ZHENG Hongbo, CHEN Huizhong & CAO JunjiLaboratory of Marine Geology, Tongji University, Shanghai 200092, China Institute of Earth Environment, Chinese Academy of Sciences, Xi’an 710054, China Institute of Environment and Engineering of Cold and Arid Regio 2002Chinese Science Bulletin2002,47,8:6

16Microbial community structure and diversity in deep-sea hydrothermal vent sediments along the Eastern Lau Spreading Centre显示文摘The aim of this study is to investigate microbial structures and diversities in five active hydrothermal fields' sediments along the Eastern Lau Spreading Centre (ELSC) in the Lau Basin (southwest Pacific). Microbial communities were surveyed by denatured gradient gel electrophoresis (DGGE) and clone library analysis of 16S rRNA genes. The differences in microbial community structures among sediment samples from the five deep-sea hydrothermal sites were revealed by DGGE profiles. Cluster analysis of DGGE profiles separated the five hydrothermal samples into two groups. Four different 16S rRNA gene clone libraries, representing two selected hydrothermal samples (19-4TVG8 and 19-4TVG11), were constructed. Twenty-three and 32 phylotypes were identified from 166 and 160 bacterial clones respectively, including Proteobacteria, Bacteroidetes, Firmicutes, Nitrospirae and Planctomycetes. The phylum Proteobacteria is dominant in both bacterial libraries with a predominance of Gamma-Proteobacteria. A total of 31 and 25 phylotypes were obtained from 160 and 130 archaeal clones respectively, including Miscellaneous Crenarchaeotic Group, Marine Group Ⅰ and Ⅲ, Marine Benthic Group E, Terrestrial Hot Spring Crenarchaeota and Deep-sea Hydrothermal Vent Euryarchaeota. These results show a variety of clones related to those involved in sulfur cycling, suggesting that the cycling and utilization of sulfur compounds may extensively occur in the Lau Basin deep-sea hydrothermal ecosystem.WEI Manman ZHANG Rubing WANG Yuguang JI Houguo ZHENG Jia CHEN Xinhua ZHOU Hongbo 2013Acta Oceanologica Sinica2013,32,2:6
17Mechanically Strong Proteinaceous Fibers:Engineered Fabrication by Microfluidics显示文摘Lightweight and mechanically strong natural silk fibers have been extensively investigated over the past decades.Inspired by this research,many artificial spinning techniques(wet spinning,dry spinning,electrospinning,etc.)have been developed to fabricate robust protein fibers.As the traditional spinning methods provide poor control over the as-spun fibers,microfluidics has been integrated with these techniques to allow the fabrication of biological fibers in a well-designed manner,with simplicity and cost efficiency.The mechanical behavior of the developed fibers can be precisely modulated by controlling the type iop and size of microfluidic channel,flow rate,and shear force.This technique has been successfully used to manufacture a broad range of protein fibers,and can accelerate the production and application of protein fibers in various fields.This review outlines recent progress in the design and fabrication of protein-based fibers based on microfluidics.We first briefly discuss the natural spider silk-spinning process and the microfluidics spinning process.Next,the fabrication and mechanical properties of regenerated protein fibers via microfluidics are discussed,followed by a discussion of recombinant protein fibers.Other sourced protein fibers are also reviewed in detail.Finally,a brief outlook on the development of microfluidic technology for producing protein fibers is presented.Jing Sun Jingsi Chen Kai Liu Hongbo Zeng 2021Engineering2021,7,5:5
18Protective effect of oxysophoridine on cerebral ischemia/reperfusion injury in mice显示文摘Oxysophoridine, a new alkaloid extracted from Sophora alopecuroides L., has been shown to have a protective effect against ischemic brain damage. In this study, a focal cerebral ischemia/reperfusion injury model was established using middle cerebral artery occlusion in mice. Both 62.5, 125, and 250 mg/kg oxysophoridine, via intraperitoneal injection, and 6 mg/kg nimodipine, via intragastric administration, were administered daily for 7 days before modeling. After 24 hours of reperfusion, mice were tested for neurological deficit, cerebral infarct size was assessed and brain tissue was collected. Results showed that oxysophoridine at 125, 250 mg/kg and 6 mg/kg nimodipine could reduce neurological deficit scores, cerebral infarct size and brain water content in mice. These results provided evidence that oxysophoridine plays a protective role in cerebral ischemia/reperfusion injury. In addition, oxysophoridine at 62.5, 125, and 250 mg/kg and 6 mg/kg nimodipine increased adenosine-triphosphate content, and decreased malondialdehyde and nitric oxide content. These compounds enhanced the activities of glutathione-peroxidase, superoxide dismutase, catalase, and lactate dehydrogenase, and decreased the activity of nitric oxide synthase. Protein and mRNA expression levels of N-methyl-D-aspartate receptor subunit NR1 were markedly inhibited in the presence of 250 mg/kg oxysophoridine and 6 mg/kg nimodipine. Our experimental findings indicated that oxysophoridine has a neuroprotective effect against cerebral ischemia/reperfusion injury in mice, and that the effect may be due to its ability to inhibit oxidative stress and expression of the N-methyl-D-aspartate receptor subunit NR1.Hongbo Wang Yuxiang Li Ning Jiang Xiaoping Chen Yi Zhang Kuai Zhang Tengfei Wang Yinju Hao Lin Ma Chengjun Zhao Yanrong Wang Tao Sun Jianqiang Yu 2013Neural Regeneration Research2013,8,15:5
19Clinical applications of free medial tibial flap with posterior tibial artery for head and neck reconstruction after tumor resection显示文摘Tumor resection causes damage in the head and neck which creates problems in swallowing, chewing, articulation,and vision, all of which seriously affect patients' quality of life. In this work, we evaluated the application of a free medial tibial flap in reconstruction of head and neck defects after tumor resection. We discussed the anatomy,surgical technique, and the advantages and disadvantages of the flap. We found several benefits for the flap, such as,it is especially effective for the defects that require thin-layer epithelium to cover or the separated soft tissue defect;a two-team approach can be used because the donor site is far away from the head and neck; and the flap is easy to integrate because of the subcutaneous fat layer of the free medial tibial flap is thin and the flap is soft. Thus, the medial tibial flap could replace the forearm flap for certain applications.Qi Zhong Jugao Fang Zhigang Huang Xiaohong Chen Lizhen Hou Yang Zhang Pingdong Li Hongzhi Ma Hongbo Xu 2017Chinese Journal of Cancer Research2017,29,3:5
20Core-shell structured MoS_2@S spherical cathode with improved electrochemical performance for lithium-sulfur batteries显示文摘To suppress shuttling effect and improve electrochemical performance of the sulfur cathode for lithiumsulfur batteries, core-shell structured MoS_2 @S spherical cathode has been synthesized through a chemical route using MnC03 as template. The MoS_2 shells consist of MoS_2 nanosheets. For comparison, MoS_2/S cathode has also been synthesized through melting and diffusion of sulfur to commercial MoS_2 powders. The electrochemical performance of the MoS_2@S and MoS_2/S cathodes have been evaluated using cyclic voltammetry, discharge/charge cycling, electrochemical impedance spectroscopy coupled with impedance fitting. The electrochemical performance of the MoS_2@S spherical cathode has been much improved compared with that of MoS_2/S. The capacity of the MoS_2@S spheres can reach 1185.7 mAhg-1 at 0.2 C and 955.1 mAhg^(-1) at 1 C with initial-cycle coulombic efficiency of 90%. The capacity fading of each cycle is 0.1 % during 200 lithiation/delithiation cycles. The MoS_2@S spherical cathode with high cyclic capacity and stability is promising cathode candidate for lithium-sulfur batteries.Songpu Cheng Xiaohong Xia Hongbo Liu Yuxi Chen 2018Journal of Materials Science & Technology2018,34,10:5
