| 1 | Recent research advances of self-discharge in supercapacitors:Mechanisms and suppressing strategies显示文摘Supercapacitors are one of the most promising energy storage devices in the fields of vehicle transportation,flexible electronic devices,aerospace,etc.However,the existed self-discharge that is the spontaneous voltage decay after supercapacitors are fully charged,brings about the wide gap between experimental studies and practical utilization of supercapacitors.Although eliminating the selfdischarge completely is not reachable,suppressing the self-discharge rate to the lowest point is possible and feasible.So far,the significant endeavors have been devoted to achieve this goal.Herein,we summary and discuss the possible mechanisms for the self-discharge and the underlying influence factors.Moreover,the strategies to suppress the self-discharge are systemically summed up by three independent but unified aspects:modifying the electrode,modulating the electrolyte and tuning the separator.Finally,the major challenges to suppress the self-discharge of supercapacitors are concluded and the promising strategies are also pointed out and discussed.This review is presented with the view of serving as a guideline to suppress the self-discharge of supercapacitors and to across-the-board facilitate their widespread application. | Kunlun Liu Chang Yu Wei Guo Lin Ni Jinhe Yu Yuanyang Xie Zhao Wang Yongwen Ren Jieshan Qiu | 2021 | Journal of Energy Chemistry2021，30，7： | 6 |
| 2 | Geospatial Service Web:towards integrated cyberinfrastructure for GIScience显示文摘A geospatial cyberinfrastructure is needed to support advanced GIScience research and education activities.However,the heterogeneous and distributed nature of geospatial resources creates enormous obstacles for building a unified and interoperable geospatial cyberinfrastructure.In this paper,we propose the Geospatial Service Web(GSW)to underpin the development of a future geospatial cyberinfrastructure.The GSW excels over the traditional spatial data infrastructure by providing a highly intelligent geospatial middleware to integrate various geospatial resources through the Internet based on interoperable Web service technologies.The development of the GSW focuses on the establishment of a platform where data,information,and knowledge can be shared and exchanged in an interoperable manner.Theoretically,we describe the conceptual framework and research challenges for GSW,and then introduce our recent research toward building a GSW.A research agenda for building a GSW is also presented in the paper. | GONG Jianya WU Huayi ZHANG Tong GUI Zhipeng LI Zhenlong YOU Lan SHEN Shengyu ZHENG Jie GENG Jing QI Kunlun YANG Wenjing LI Zhenqiang YU Jingmin | 2012 | Geo-Spatial Information Science2012，15，2： | 5 |
| 3 | D609 protects retinal pigmented epithelium as a potential therapy for age-related macular degeneration显示文摘Accumulated oxidative damage may lead to irreversible retinal pigmented epithelium(RPE)cell death,which is considered to be the primary cause of dry age-related macular degeneration(AMD),leading to blindness in the elderly.However,an effective therapy for this disease is lacking.Here,we described a robust high-content screening procedure with a library of 814 protective compounds and found that D609 strongly protected RPE cells from sodium iodate(SI)-induced oxidative cell death and prolonged their healthy survival.D609 effectively attenuated excessive reactive oxygen species(ROS)and prevented severe mitochondrial loss due to oxidative stress in the RPE cells.Surprisingly,the potent antioxidative effects of D609 were not achieved through its own reducibility but were primarily dependent on its ability to increase the expression of metallothionein.The injection of this small water-soluble molecule also showed an explicit protective effect of the RPE layer in an SI-induced AMD mouse model.These findings suggested that D609 could serve as a novel antioxidative protector of RPE cells both in vitro and in vivo and unveiled a novel antioxidative mechanism of D609,which may ultimately have clinical applications for the treatment of AMD. | Bowen Wang Li Wang Sijie Gu Yankun Yu Huaxing Huang Kunlun Mo He Xu Fanzhu Zeng Yichen Xiao Lulu Peng Chunqiao Liu Nan Cao Yizhi Liu Jin Yuan Hong Ouyang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 4 | Rock damage and fracturing induced by high static stress and slightly dynamic disturbance with acoustic emission and digital image correlation techniques显示文摘A series of coupled static-dynamic loading tests is carried out in this study to understand the effect of slightly dynamic disturbance on the rocks under high static stress.The acoustic emission(AE)and digital image correlation(DIC)techniques are combined to quantitatively characterize the damage and fracturing behaviors of rocks.The effects of three influencing factors,i.e.initial static stress,disturbance amplitude,and disturbance frequency,on the damage and fracturing evolution are analyzed.The experimental results reveal the great differences in AE characteristics and fracturing behaviors of rocks under static loads and coupled static-dynamic loads.Both the Kaiser effect and Felicity effect are observed during the disturbance loading process.The crack initiation,stable and unstable propagation in the highly-stressed rocks can be triggered by cyclic disturbance loads,and more local tensile splitting cracks are found in the rocks subjected to coupled static-dynamic loads.The damage and fracturing evolution of rocks during cyclic disturbances can be divided into two stages,i.e.steady and accelerated stages,and the increase rate and proportion of each stage are greatly affected by these influencing factors.High initial static stress,low disturbance frequency,and high disturbance amplitude are considered to be adverse factors to the stability of the rocks,which would induce a high increase rate of the steady stage and a high proportion of the accelerated stage within the whole disturbance period.Based on the two-stage damage evolution trend,a linear-exponential damage model is employed to predict the instability of the rocks under coupled static-dynamic loads. | Shuting Miao Peng-Zhi Pan Petr Konicek Peiyang Yu Kunlun Liu | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，5： | 2 |

| 6 | A long/short-range interconnected carbon with well-defined mesopore for high-energy-density supercapacitors显示文摘Amorphous carbon derived from biomass unusually combines the merits of large specific surface area and abundant micropores,offering massive anchoring points for ion adsorption in electrolyte.Nevertheless,the short-range ordered structure in amorphous carbon hinders the fast electron transfer.Conversely,graphitic carbon with long-range ordered structure is beneficial for electron transfer.Thus,a low-cost strategy is required to marry hierarchical porous structure with long-range ordered structure,resulting in a long/short-range interconnected porous carbon and then leading to fast ion and electron transfer.Herein,we modified the solid-phase conversion process of biomass by employing the features of liquid-phase carbonization for petroleum asphalt.With the assistance of asphalt,the large specific surface area(>2,000 m^(2)·g^(-1)),high ratio of mesopores(ca.60%)together with long-range ordered structure are in-situ created in as-made porous carbon.Thanks to the well configured structure in small scale,the as-made co-converted carbon can be operated in high-viscosity EMIMBF4 electrolyte with a superior capacitance(315 F·g^(-1)@1 A·g^(-1)).Besides,the as-assembled symmetric supercapacitor can deliver a super-high specific energy of 174 Wh·kg^(-1)@2.0 kW·kg^(-1).This work provides a new version for designing highly porous biomass-derived carbon with long/short-range alternating structure at molecular level. | Yuanyang Xie Chang Yu Wei Guo Lin Ni Zhao Wang Jinhe Yu Le Yang Rong Fu Kunlun Liu Jieshan Qiu | 2022 | Nano Research2022，15，2： | 1 |

| 8 | Electric stimulation and decimeter wave therapy improve the recovery of injured sciatic nerves显示文摘Drug treatment, electric stimulation and decimeter wave therapy have been shown to promote the repair and regeneration of the peripheral nerves at the injured site. This study prepared a Mackinnon's model of rat sciatic nerve compression. Electric stimulation was given immediately after neurolysis, and decimeter wave radiation was performed at 1 and 12 weeks post-operation. Histological observation revealed that intraoperative electric stimulation and decimeter wave therapy could improve the local blood circulation of repaired sites, alleviate hypoxia of compressed nerves, and lessen adhesion of compressed nerves, thereby decreasing the formation of new entrapments and enhancing compressed nerve regeneration through an improved microenvironment for regen- eration. Immunohistochemical staining results revealed that intraoperative electric stimulation and decimeter wave could promote the expression of S-100 protein. Motor nerve conduction velocity and amplitude, the number and diameter of myelinated nerve fibers, and sciatic functional index were significantly increased in the treated rats. These results verified that intraoperative electric stimulation and decimeter wave therapy contributed to the regeneration and the recovery of the functions in the compressed nerves. | Feng Zhao Wei He Yingze Zhang Dehu Tian Hongfang Zhao Kunlun Yu Jiangbo Bai | 2013 | Neural Regeneration Research2013，8，21： | 1 |

| 10 | Rapid Acquisition of High-Quality SARS-CoV-2 Genome via Amplicon-Oxford Nanopore Sequencing显示文摘Genome sequencing has shown strong capabilities in the initial stages of the COVID-19 pandemic such as pathogen identification and virus preliminary tracing.While the rapid acquisition of SARS-Co V-2 genome from clinical specimens is limited by their low nucleic acid load and the complexity of the nucleic acid background.To address this issue,we modified and evaluated an approach by utilizing SARS-Co V-2-specific amplicon amplification and Oxford Nanopore Prometh ION platform.This workflow started with the throat swab of the COVID-19 patient,combined reverse transcript PCR,and multi-amplification in one-step to shorten the experiment time,then can quickly and steadily obtain high-quality SARS-Co V-2 genome within 24 h.A comprehensive evaluation of the method was conducted in 42 samples:the sequencing quality of the method was correlated well with the viral load of the samples;high-quality SARS-Co V-2 genome could be obtained stably in the samples with Ct value up to 39.14;data yielding for different Ct values were assessed and the recommended sequencing time was 8 h for samples with Ct value of less than 20;variation analysis indicated that the method can detect the existing and emerging genomic mutations as well;Illumina sequencing verified that ultra-deep sequencing can greatly improve the single read error rate of Nanopore sequencing,making it as low as 0.4/10,000 bp.In summary,high-quality SARS-Co V-2 genome can be acquired by utilizing the amplicon amplification and it is an effective method in accelerating the acquisition of genetic resources and tracking the genome diversity of SARSCo V-2. | Yi Yan Ke Wu Jun Chen Haizhou Liu Yi Huang Yong Zhang Jin Xiong Weipeng Quan Xin Wu Yu Liang Kunlun He Zhilong Jia Depeng Wang Di Liu Hongping Wei Jianjun Chen | 2021 | Virologica Sinica2021，36，5： | 0 |
| 11 | Augmented hydrogen production by gasification of ball milled polyethylene with Ca(OH)2 and Ni(OH)2显示文摘Polymer thermal recycling for hydrogen production is a promising process to recover such precious element from plastic waste. In the present work a simple but efficacious high energy milling pretreatment is proposed to boost H2 generation during polyethylene gasification. The polymer is comilled with calcium and nickel hydroxides and then it is subjected to thermal treatment. Results demonstrate the key role played by the calcium hydroxide that significantly ameliorates hydrogen production. It reacts in solid state with the polyethylene to fonn directly carbonate and hydrogen. In this way, the CO2 is immediately captured in solid fonn, thus shifting the equilibrium toward H2 generation and obtaining high production rate (>25 L/mol CH2). In addition, high amounts of the hydroxide prevent excessive methane fonnation, so the gas product is almost pure hydrogen (~95%). | Giovanni Cagnetta Kunlun Zhang Qiwu Zhang Jun Huang Gang Yu | 2019 | Frontiers of Environmental Science & Engineering2019，13，1： | 0 |
| 12 | Correlation between self-discharge behavior and heteroatoms over doped carbon sheets for enhanced pseudocapacitance显示文摘For electric double layer supercapacitors,carbon materials originating from the purely physical energystorage mechanism limit the improvement in the capabilities of charge storage.To solve this problem,doping heteroatoms into carbon skeleton is a promising&charming strategy for enhancing electrochemical performance by providing the extra pseudocapacitance.However,the self-discharge behavior of such heteroatom-doped supercapacitors has been a challenging issue for a long time.Here,the porous carbon nanosheets with a tunable total content of heteroatoms are chosen as a demo to systemically decouple the correlation between the total content of heteroatoms and the specific capacitance as well as the self-discharge behavior.The capacitance changes in a range of 164–331 F g^(-1)@1 A g^(-1)with the increased total contents of doped heteroatom,strongly dependent on and sensitive to the total content of heteroatoms.The voltage retention rate and capacitance retention rate for the porous carbon nanosheets with a tunable total content of heteroatoms completely present a quick decline tendency as the increase in the content of heteroatoms,changing from 58%to 34%and 74%to 39%,respectively,indicative of a linear negative relationship.More importantly,the self-discharge mechanisms are elaborately explored and follow the combination of activation-and diffusion-controlled Faradic reactions.This work illustrates the diverse impacts of the doped heteroatoms on the electrochemical performance of supercapacitors,covering specific capacitance and self-discharge behavior,and highlights the importance of balancing the contents of doped heteroatoms in energy storage fields. | Kunlun Liu Chang Yu Yuanyang Xie Wei Guo Jinhe Yu Lin Ni Zhao Wang Rong Fu Jieshan Qiu | 2022 | Journal of Energy Chemistry2022，31，9： | 0 |
