| 1 | Additive manufacturing of metals:Microstructure evolution and multistage control显示文摘As a revolutionary industrial technology,additive manufacturing creates objects by adding materials layer by layer and hence can fabricate customized components with an unprecedented degree of freedom.For metallic materials,unique hierarchical microstructures are constructed during additive manufacturing,which endow them with numerous excellent properties.To take full advantage of additive manufacturing,an in-depth understanding of the microstructure evolution mechanism is required.To this end,this review explores the fundamental procedures of additive manufacturing,that is,the formation and binding of melt pools.A comprehensive processing map is proposed that integrates melt pool energy-and geometry-related process parameters together.Based on it,additively manufactured microstructures are developed during and after the solidification of constituent melt pool.The solidification structures are composed of primary columnar grains and fine secondary phases that form along the grain boundaries.The post-solidification structures include submicron scale dislocation cells stemming from internal residual stress and nanoscale precipitates induced by intrinsic heat treatment during cyclic heating of adjacent melt pool.Based on solidification and dislocation theories,the formation mechanisms of the multistage microstructures are thoroughly analyzed,and accordingly,multistage control methods are proposed.In addition,the underlying atomic scale structural features are briefly discussed.Furthermore,microstructure design for additive manufacturing through adjustment of process parameters and alloy composition is addressed to fulfill the great potential of the technique.This review not only builds a solid microstructural framework for metallic materials produced by additive manufacturing but also provides a promising guideline to adjust their mechanical properties. | Zhiyuan Liu Dandan Zhao Pei Wang Ming Yan Can Yang Zhangwei Chen Jian Lu Zhaoping Lu | 2022 | Journal of Materials Science & Technology2022，，5： | 27 |
| 2 | Herbal decoctosome is a novel form of medicine显示文摘Traditionally, herbal medicine is consumed by drinking decoctions produced by boiling herbs with water. The functional components of the decoction are heat stable. Small RNAs(sRNAs) were reported as a new class of functional components in decoctions. However, the mechanisms by which sRNAs survive heat treatment of the decoction and enter cells are unclear.Previous studies showed that plant-derived exosome-like nanoparticles(ELNs), which we call botanosomes, could deliver therapeutic reagents in vivo. Here, we report that heat-stable decoctosomes(ELNs) from decoctions have more therapeutic effects than the decoctions in vitro and demonstrate therapeutic efficacy in vivo. Furthermore, sRNAs, such as HJT-sRNA-m7 and PGY-sRNA-6, in the decoctosome exhibit potent anti-fibrosis and anti-inflammatory effects, respectively. Decoctosome is comprised of lipids, chemical compounds, proteins, and s RNAs. A medical decoctosome mimic is called bencaosome. A single lipid sphinganine(d22:0) identified in the decoctosome was mixed and heated with the synthesized sRNAs to form the simplest bencaosome. This simple bencaosome structure was identified by critical micelle concentration(cmc) assay that sRNAs coassembled with sphinganine(d22:0) to form the lipid layers of vesicles. The heating process facilitates co-assembly of sRNAs and sphinganine(d22:0) until a steady state is reached. The artificially produced sphinganine-HJT-sRNA-m7 and sphinganinePGY-sRNA-6 bencaosomes could ameliorate bleomycin-induced lung fibrosis and poly(I:C)-induced lung inflammation, respectively, following oral administration in mice. Our study not only demonstrates that the herbal decoctosome may represent a combinatory remedy in precision medicine but also provides an effective oral delivery route for nucleic acid therapy. | Xiaoyun Li Zhu Liang Jianchao Du Zhiqing Wang Song Mei Zhiqing Li Yan Zhao DANDan Zhao Yiming Ma Jun Ye Jiantao Xu Yu Zhao Jiahui Chang Yuhao Qin Lanlan Yu Chenxuan Wang Chengyu Jiang | 2019 | Science China(Life Sciences)2019，62，3： | 26 |
| 3 | Surveillance, epidemiology, and pathogen spectrum of hand, foot, and mouth disease in mainland of China from 2008 to 2017显示文摘Hand,foot and mouth disease(HFMD)was reported in May 2,2008 to be the 38th legally notifiable disease in China's National Notifiable Disease Reporting and Surveillance System.In order to solve the infection,an extensive three-level HFMD surveillance laboratory network was established.In this study,the framework of that network is assessed and the incidence of HFMD in China from 2008 to 2017 is reported using a descriptive epidemiologic method.During these 10 years,a series of techniques have been widely applied in all the network laboratories.Using information and material obtained from the network,a virus bank and database containing 18,238 viruses were established.Nationally,18,184,834 HFMD cases,including 152,436 severe cases and 3633 fatal cases,were reported in mainland of China.The average annual incidence in the population was 133.99/100,000 people,with a maximum incidence of 205.06/100,000 people in 2014.The incidence and mortality rates of HFMD were the highest in children aged 1–2 years.The numbers of reported cases fluctuated,with a high incidence observed every 2 years.An overall increase in the number of reported cases was also observed throughout the study period.Despite this,the incidence of severe cases and the mortality rate have been decreasing.High-risk regions are located in southern,eastern,and central China.Two peaks of HFMD infection cases were observed annually except for Northeast China.Different proportions of enterovirus serotypes were observed during the studied years.The predominant enterovirus varies from year to year,but the disease severity is always closely related to the specific serotype.EV-A71 is the dominant serotype associated with severe and fatal cases,with constituent ratios of 70.03%and 92.23%,respectively.The studied highly sensitive and efficient surveillance network provides information that is critical for prevention and control of the disease.It is extremely necessary and important to continuously conduct extensive virological surveillance for HFMD. | Tianjiao Ji Taoli Han Xiaojuan Tan Shuangli Zhu Dongmei Yan Qian Yang Yang Song Aili Cui Yan Zhang Naiying Mao Songtao Xu Zhen Zhu Dandan Niu Yong Zhang Wenbo Xu | 2019 | Biosafety and Health2019，1，1： | 26 |
| 4 | Plant-derived phosphocholine facilitates cellular uptake of anti-pulmonary fibrotic HJT-sRNA-m7显示文摘Pulmonary fibrosis, a progressive chronic disease with a high mortality rate, has limited treatment options. Currently, lung transplantation remains the only effective treatment. Here we report that a small RNA, HJT-sRNA-m7, from a Chinese herbal medicine Hong Jing Tian(HJT, RHODIOHAE CRENULATAE RADIX ET RHIZOMA, Rhodiola crenulata) can effectively reduce the expressions of fibrotic hallmark genes and proteins both in alveolar in vitro and in mouse lung tissues in vivo. We also discovered over one hundred oil-soluble chemicals from HJT decoctions, most of which are found in lipid extracts from other Chinese herbals decoctions, including Pu Gong Ying(PGY, TARAXACI HERBA, Taraxacum mongolicum), Chuan Xin Lian(CXL, changed to 'ANDROGRAPHIS HERBA, Andrographis paniculata'), and Jin Yin Hua(JYH, lonicera japonica or Honeysuckle). We identified the active component in these decoctions as two forms of phosphocholines, PC(18:0/18:2) and PC(16:0/18:2). These PCs potentially could form liposomes with small RNAs to enter human alveolar and gastric cells. Our experimental results suggest an unprecendent lipid complex route through which botanic small RNA can enter human bodies.Our results provide an innovative treatment strategy for oral delivery of siRNAs as therapeutic medication. | Jianchao Du Zhu Liang Jiantao Xu Yan Zhao Xiaoyun Li Yanli Zhang DANDan Zhao Ruxuan Chen Yang Liu Trupti Joshi Jiahui Chang Zhiqing Wang Yanxu Zhang Jindong Zhu Qiang Liu Dong Xu Chengyu Jiang | 2019 | Science China(Life Sciences)2019，62，3： | 21 |
| 5 | Effects of mulberry leaf flavonoid and resveratrol on methane emission and nutrient digestion in sheep显示文摘As a new type of methane control agent, natural plant extract has been widely studied in recent years,but in vivo studies are few. This study was to investigate the effects of the dietary supplementation of 2 different polyphenols on the methane(CH4) emission and digestion metabolism in sheep. Ten healthy crossbred sheep(Dorper(?)× small-tailed Han ♀; BW 60.0 ± 1.73 kg) were used in a change-over design.The sheep were fed the following 3 diets in the present study: the basal diet(CON) with no supplementation; the basal diet supplemented with 2 g mulberry leaf flavonoid(MLF) per day per sheep; the basal diet supplemented with 0.25 g resveratrol(RES) per day per sheep. Both MLF and RES reduced CH4 emission scaled to metabolic weight per kilogram of DMI and CO2 output scaled to metabolic weight, but the effect of RES was significant(P < 0.05). Both MLF and RES significantly improved apparent digestibility of DM, OM, NDF, ADF, and nitrogen, but the effect of RES was significant(P < 0.05). Both MLF and RES significantly improved ME(P < 0.05) and reduced energy losses in CH4 emission(P > 0.05). In conclusion, MLF and RES can improve the digestibility of nutrients, the utilization of nutrients and energy, and reduce CH4 emission, but they are not conducive to nitrogen retention. | Dandan Chen Xiaolin Chen Yan Tu Bo Wang Can Lou Tao Ma Qiyu Diao | 2015 | Animal Nutrition2015，，4： | 14 |
| 6 | Development and application of mechanized maize harvesters显示文摘Maize harvesting is one of the most important filed operations of maize production.As the accelerating development of maize industry,mechanized maize harvesting is widely accepted and used by farmers in the world.According to the harvesting methods,maize harvesters could be classified into two types,one is maize-for-grain harvesters,including pickers and grain harvesters,the other is whole plant harvesters,including forage harvesters and combined grain-stover harvesters.Structure characteristics,appropriate areas and relative technologies of those harvesters are described in this paper,i.e.,pickers are suitable for multi-crop areas,Grain harvesters are mainly for one-crop areas when grain moisture content is lower than 25%,combined grain-stover harvesters are applicable in agro-pastoral ecotone,and forage harvesters are capable in large-scaled animal husbandry farming areas where large amount of silage are required.Meanwhile,the future development trend of the different harvesters is predicted.Big horsepower engines,enhanced working efficiency,automation and intelligence are required by large scaled farms.As maize breeding development,more varieties that are suitable for grain harvesting are put into practice,so grain combine harvesters will be popular in future. | Yang Li Cui Tao Qu Zhe Li Kehong Yin Xiaowei Han Dandan Yan Bingxin Zhao Dongyue Zhang Dongxing | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 13 |
| 7 | Effects of Chinese herbs in children with Henoch-Schonlein purpura nephritis:a randomized controlled trial显示文摘OBJECTIVE:To research the curative effect of Chinese herbs for clearing away heat,promoting diuresis,nourishing the kidney,and consolidating essence in children with Henoch-Schonlein purpura nephritis(HSPN)with internal accumulation of damp-toxin using randomized controlled observations on large samples.To seek the mechanism of the therapy and its scope of indications.METHODS:Overall,186 children with HSPN were randomly divided into two groups:treatment group(n=126)treated with Chinese herbs for clearing heat and promoting diuresis and a control group(n=60)treated with Western Medicine.The treatment was carried out for three courses of 4weeks each.We recorded changes in patient urine routines,24 h urinary protein,blood-coagulating series,immunoglobulin and T-cell subgroups,and improvements in main symptoms.We evaluated the alleviation of clinical symptoms and the improvement of proteinuria,hematuria,and other lab-oratory test results.Finally,we analyzed the patient population suitable for this therapy according to the relationship between the grouping of patient body weight and curative effect.RESULTS:Damp-heat syndrome improved in the treatment group,with a significant difference in total effective rate after a 4-week treatment(χ2=13.5220,P=0.0002)and in curative rate after a12-week treatment(χ2=6.3410,P=0.0118),compared to those in the control group.The curative effect in the treatment group was greater than that in the control group but there was no statistical difference between the two groups.The curative effect after a 4-week treatment of patients in the treatment group weighing 30 kg or less based on Traditional Chinese Medicine(TCM)signs and urinary protein was significantly greater than that in the control group.However,there was no statistical difference in the curative effect on urinary red cells and various indexes after a 12-week treatment between the two groups.CONCLUSION:Therapy for clearing away heat,promoting diuresis,nourishing the kidney,and consolidating essence using TCM is effective in children with HSPN from internal accumulation of damp-toxin.The therapy is especially suitable for patients weighing 30 kg or less.The curative effect may be related to the improvement of immune function and blood-coagulation. | Dandan Ding Huimin Yan Xiaofang Zhen | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 12 |

| 10 | Effect of supplementation of allicin on methanogenesis and ruminal microbial flora in Dorper crossbred ewes显示文摘Background: Garlic extracts have been reported to be effective in reducing methanogenesis. Related mechanisms are not well illustrated, however, and most studies have been conducted in vitro. This study investigates the effects of supplementary allicin(AL) in sheep diet on in vivo digestibility, rumen fermentation, and shifts of microbial flora.Methods: Two experiments were conducted using Dorper × thin-tailed Han crossbred ewes. In experiment 1,eighteen ewes(60.0 ± 1.73 kg BW) were randomly assigned for 29 days to either of two dietary treatments: a basal diet or the basal diet supplemented with 2.0 g AL/head?day to investigate supplementary AL on nutrient digestibility and methane emissions. In experiment 2, six ewes(65.2 ± 2.0 kg BW) with ruminal canulas were assigned to the same two dietary treatments as in experiment 1 for 42 days to investigate supplementary AL on ruminal fermentation and microbial flora. The methane emissions were determined using an open-circuit respirometry system and microbial assessment was done by q PCR of 16 S r RNA genes.Results: Supplementary AL increased the apparent digestibility of organic matter(P < 0.001), nitrogen(P = 0.006),neutral detergent fiber(P < 0.001), and acid detergent fiber(P = 0.002). Fecal nitrogen output was reduced(P = 0.001)but urinary nitrogen output was unaffected(P = 0.691), while nitrogen retention(P = 0.077) and nitrogen retention/nitrogen intake(P = 0.077) tended to increase. Supplementary AL decreased methane emissions scaled to metabolic bodyweight by 5.95 %(P = 0.007) and to digestible organic matter intake by 8.36 %(P = 0.009). Ruminal p H was unaffected(P = 0.601) while ammonia decreased(P = 0.024) and total volatile fatty acids increased(P = 0.024) in response to supplementary AL. Supplementary AL decreased the population of methanogens(P = 0.001) and tended to decrease that of protozoans(P = 0.097), but increased the populations of F. succinogenes(P < 0.001), R. flavefaciens(P = 0.001), and B. fibrisolvens(P = 0.001).Conclusions: Supplementation of AL at 2.0 g/head?day effectively enhanced OM, N, NDF, and ADF digestibility and reduced daily methane emissions(L/kg BW0.75) in ewes, probably by decreasing the population of ruminal protozoans and methanogens. | Tao Ma Dandan Chen Yan Tu Naifeng Zhang Bingwen Si Kaidong Deng Qiyu Diao | 2016 | Journal of Animal Science and Biotechnology2016，7，2： | 9 |
| 11 | miR164c and miR168a regulate seed vigor in rice^∞显示文摘Micro RNAs(miRNAs)are key regulators of gene expression in many important biological processes of plants.However,few miRNAs have been shown to regulate seed vigor.Here,we conducted microarray assays to analyze miRNA expression levels in seeds of the rice(Oryza sativa L.)cultivar ZR02.Results showed significant differences in the expression of 11 miRNAs between artificially aged and untreated control seeds.Among these,osa-miR164c was transcriptionally upregulated,while osamiR168 a was downregulated in artificially aged seeds;this was verified by quantitative real-time PCR analysis.Under the same aging condition,osa-miR164c overexpression in OE164c transgenic seeds and osa-miR168a silencing in MIM168a transgenic seeds of the rice cultivar Kasalath led to lower germination rates,whereas osa-miR164c silencing Rin MIM164c and osa-miR168a overexpression in OE168a resulted in higher seed germination rates compared with wild-type seeds.Meanwhile,changes in cytomembrane permeability of seeds and in the expression level of osa-miR164c target genes(OsPM27 and OsPSK5)and osamiR168a target genes(OsAGO1 and OsPTR2)under aging conditions coincided with changes in seed vigor induced by osa-miR164c and osa-miR168 a.Thus,genetic manipulation of miRNAs has important implications in the development of crop cultivars with high vigor and extended life span of seeds. | Yan Zhou Shiqi Zhou Liping Wang Duo Wu Hailan Cheng Xu Du Dandan Mao Chunlai Zhang Xiaocheng Jiang | 2020 | Journal of Integrative Plant Biology2020，62，4： | 7 |

| 13 | Distribution and risk factors of hand, foot, and mouth disease in Changchun, northeastern China显示文摘Hand,foot,and mouth disease(HFMD)is a public health problem,and there have been increasing numbers of outbreaks in China's Mainland since 2008.Over17,000 HFMD cases have been reported in Changchun between 2008 and 2011.This study characterized the temporal and spatial distribution of the disease and identified the risk factors for HFMD.The main findings were as follows:(i)there were significant differences in HFMD incidence among age groups,with 86.8%of reported cases in children younger than 5 years old,and boys showed a higher incidence than girls(\6 years);(ii)The disease affected the whole region and spanned a large geographic area,but there was a higher incidence in urban areas(median=242 per 10,000 persons)and urban–rural border areas(median=135 per 10,000 persons),compared with rural areas(median=75 per 10,000 persons);and(iii)the incidence of HFMD in Changchun was significantly associated with the distance to the nearest freeway,GDP per capita,and the type of township. | Li Yan Xinlou Li Yaqin Yu Sake J.de Vlas Yapin Li Dandan Wang Yanli Li Yuan Yin Jing Wu Hong Liu Hong Yang Bo Li Liqun Fang Wuchun Cao | 2014 | Chinese Science Bulletin2014，59，5： | 7 |
| 14 | Epidemiology of urticaria in China:a population-based study显示文摘Background:Urticaria is a common skin disease characterized by episodes of wheals,and it has a negative effect on patients’quality of life.Large-scale population-based epidemiological studies of urticaria are scarce in China.The aim of this survey was to determine the prevalence,clinical forms,and risk factors of urticaria in the Chinese population.Methods:This survey was conducted in 35 cities from 31 provinces,autonomous regions,and municipalities of China.Two to three communities in each city were selected in this investigation.Participants completed questionnaires and received dermatological examinations.We analyzed the prevalence,clinical forms,and risk factors of urticaria.Results:In total,44,875 questionnaires were distributed and 41,041 valid questionnaires were collected(17,563 male and 23,478 female participants).The lifetime prevalence of urticaria was 7.30%,with 8.26%in female and 6.34%in male individuals(P<0.05).The point prevalence of urticaria was 0.75%,with 0.79%in female and 0.71%in male individuals(P<0.05).Concomitant angioedema was found in 6.16%of patients.Adults had a higher prevalence of urticaria than adolescents and children.Living in urban areas,exposure to pollutants,an anxious or depressed psychological status,a personal and family history of allergy,thyroid diseases,and Helicobacter pylori infection were associated with a higher prevalence of urticaria.Smoking was correlated with a reduced risk of urticaria.Conclusion:This study demonstrated that the lifetime prevalence of urticaria was 7.30%and the point prevalence was 0.75%in the Chinese population;women had a higher prevalence of urticaria than men.Various factors were correlated with urticaria. | Jiaqing Li Dandan Mao Shuoshuo Liu Ping Liu Jing Tian Chenhong Xue Xiaojing Liu Ruiqun Qi Bingxue Bai Jianjun Nie Siqi Ye Yu Wang Yuye Li Qing Sun Juan Tao Shuping Guo Hong Fang Jianqin Wang Qiri Mu Quanzhong Liu Yan Ding Jianzhong Zhang | 2022 | Chinese Medical Journal2022，，11： | 6 |
| 15 | A detached petal disc assay and virus-induced gene silencing facilitate the study of Botrytis cinerea resistance in rose flowers显示文摘Fresh-cut roses(Rosa hybrida)are one of the most important ornamental crops worldwide,with annual trade in the billions of dollars.Gray mold disease caused by the pathogen Botrytis cinerea is the most serious fungal threat to cut roses,causing extensive postharvest losses.In this study,we optimized a detached petal disc assay(DPDA)for artificial B.cinerea inoculation and quantification of disease symptoms in rose petals.Furthermore,as the identification of rose genes involved in B.cinerea resistance could provide useful genetic and genomic resources,we devised a virusinduced gene silencing(VIGS)procedure for the functional analysis of B.cinerea resistance genes in rose petals.We used RhPR10.1 as a reporter of silencing efficiency and found that the rose cultivar‘Samantha’showed the greatest decrease in RhPR10.1 expression among the cultivars tested.To determine whether jasmonic acid and ethylene are required for B.cinerea resistance in rose petals,we used VIGS to silence the expression of RhLOX5 and RhEIN3(encoding a jasmonic acid biosynthesis pathway protein and an ethylene regulatory protein,respectively)and found that petal susceptibility to B.cinerea was affected.Finally,a VIGS screen of B.cinerea-induced rose transcription factors demonstrated the potential benefits of this method for the high-throughput identification of gene function in B.cinerea resistance.Collectively,our data show that the combination of the DPDA and VIGS is a reliable and highthroughput method for studying B.cinerea resistance in rose. | Xiaoqian Cao Huijun Yan Xintong Liu Dandan Li Mengjie Sui Jie Wu Hongqiang Yu Zhao Zhang | 2019 | Horticulture Research2019，6，1： | 5 |
| 16 | Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics. | Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang | 2021 | Cell Research2021，31，1： | 5 |
| 17 | A comparative study of hydrothermal aging effect on cerium and lanthanum doped Cu/SSZ-13 catalysts for NH_(3)-SCR显示文摘Ce-or La-doped Cu/SSZ-13 catalysts were prepared by a hydrothermal method and Cu,Ce or La ions were incorporated through stepwise ion exchange,The catalyst activity was measured for the ammonia selective catalytic reduction reaction.The structure and composition of catalyst were characterized by using X-ray diffraction,scanning electron microscopy,inductively coupled plasma mass spectrometry solid-state NMR,NH_(3)-TPD techniques,and the active components were examined by XPS and XANES.The results indicate that the Ce and La doping can both completely preserve the SCR activity of Cu/SSZ-13 above 300℃,but there is also a decrease of activity below 200℃.On the other hand,Ce doping is beneficial to the formation of framework aluminum,stabilizes molecular sieve framework and Cu active sites of Cu/SSZ-13,thereby improves the catalyst hydrothermal stability.But La doping will decrease the amount of framework aluminum and Cu active sites of Cu/SSZ-13 after hydrothermally aging,even destroy zeolite CHA structure.This is quite harmful to the catalyst hydrothermal stability. | Di Deng Shujun Deng Dandan He Zhiheng Wang Zhipeng Chen Yi Ji Guoping Yan Guangjin Hou Licheng Liu Hong He | 2021 | Journal of Rare Earths2021，39，8： | 5 |
| 18 | An aqueous zinc-ion hybrid super-capacitor for achieving ultrahigh-volumetric energy density显示文摘Zinc-ion hybrid super-capacitors are regarded as promising safe energy storage systems,However,the relatively low volumetric energy density has become the main bottlenecks in practical applications of portable electronic devices,In this work,the zinc-ion hybrid super-capacitor with high volumetric energy density and superb cycle stability had been constructed which employing the high-density threedimensional graphene hydrogel as cathode and Zn foil used as anode in 1 mol/L ZnSO4 electrolyte.Benefiting from the abundant ion transport paths and the abundant active sites for graphene hydrogel with high density and porous structure,the zinc-ion hybrid super-capacitor exhibited an extremely high volumetric energy density of 118.42 Wh/L and a superb power density of 24.00 kW/L,as well as an excellent long cycle life(80% retention after 30,000 cycles at 10 A/g),which was superior to the volumetric energy density of the reported zinc-ion hybrid super-capacitors.This device,based on the fast ion adsorption/deso rption on the capacitor-type graphene cathode and reversible Zn^(2+) plating/stripping on the battery-type Zn anode,which will inspire the development of zinc-ion hybrid super-capacitor in miniaturized devices. | Li Zhang Dandan Wu Gaowei Wang Yongtai Xu Hongxia Li Xingbin Yan | 2021 | Chinese Chemical Letters2021，32，2： | 4 |
| 19 | Electrospun polyporous VN nanofibers for symmetric all-solid-state supercapacitors显示文摘To promote the energy density of symmetric all-solid-state supercapacitors(SCs),efforts have been dedicated to searching for high-performance electrode materials recently. In this paper,vanadium nitride(VN) nanofibers with mesoporous structure have been fabricated by a facile electrospinning method. Their crystal structures and morphology features were characterized by X-ray diffraction,scanning electron microscopy,and transmission electron microscopy. The mesoporous structure of VN nanofibers,which can provide short electrolyte diffusion routes and conducting electron transport pathways,is beneficial to their performance as a supercapacitor electrode. Under a stable electrochemical window of 1.0 V,VN nanofibers possess an excellent mass specific capacitance of 110.8 F/g at a scan rate of 5 mV/s. Moreover,the VN nanofibers were further assembled into symmetric all-solid-state SCs,achieving a high energy density of 0.89 mW·h/cm^3 and a high power density of 0.016 W/cm^3 over an operating potential range from 0 to 1.0 V. These results demonstrate that VN nanofibers could be potentially used for energy storage devices. | Dandan ZHANG Jing LI Zhen SU Sanyuan HU Heping LI Youwei YAN | 2018 | Journal of Advanced Ceramics2018，7，3： | 3 |
| 20 | Distribution of Dissolved Inorganic Arsenic and Its Seasonal Variations in the Coastal Area of the East China Sea显示文摘Water samples were collected in the coastal area of the Changjiang Estuary on four cruises from August 2002 to May 2003. The seasonal variations of dissolved inorganic arsenic (DIAs) distributions were analyzed. The results showed that the distributions of DIAs were mainly influenced by the terrestrial input and the intrusion of the Kuroshio Subsurface Water (KSSW). The concentration of the total dissolved inorganic arsenic (TDIAs) decreased consecutively from winter to summer, while it increased in autumn. The distributions of TDIAs showed some relationships with salinity and suspended particulate matter (SPM). The relationships between DIAs speciation (including arsenite [As(Ⅲ)] and arsenate [As(Ⅴ)]), biological activity and the availabilities of the phosphate were investigated in the study area for the cruise August 2002. The ratio of As (Ⅲ)/TDIAs increased with the decrease of phosphate concentrations. In the bottom water, the As(Ⅲ)/TDIAs ratio decreased with the increasing of N/P. The concentration of TDIAs decreased 28.7% approximately after the occurrence of harmful algal blooms (HAB) because of the uptake of arsenate by algae. Further study is needed about the arsenic source/sink relationships in their vertical or horizontal profiles and the uptake mechanism during the occurrence of harmful algal blooms. | CHENG Yan REN Jingling LI Dandan LIU Sumei ZHANG Jing | 2006 | Journal of Ocean University of China2006，5，3： | 3 |
