| 1 | Adsorption of heavy metal ions from aqueous solution by carboxylated cellulose nanocrystals显示文摘A novel nanoadsorbent for the removal of heavy metal ions is reported.Cotton was first hydrolyzed to obtain cellulose nanocrystals(CNCs).CNCs were then chemically modified with succinic anhydride to obtain SCNCs.The sodic nanoadsorbent(NaSCNCs) was further prepared by treatment of SCNCs with saturated NaHCO 3 aqueous solution.Batch experiments were carried out with SCNCs and NaSCNCs for the removal of Pb 2+ and Cd 2+.The effects of contact time,pH,initial adsorption concentration,coexisting ions and the regeneration performance were investigated.Kinetic studies showed that the adsorption equilibrium time of Pb 2+ and Cd 2+ was reached within 150 min on SCNCs and 5 min on NaSCNCs.The adsorption capacities of Pb 2+ and Cd 2+ on SCNCs and NaSCNCs increased with increasing pH.The adsorption isotherm was well fitted by the Langmuir model.The maximum adsorption capacities of SCNCs and NaSCNCs for Pb 2+ and Cd 2+ were 367.6 mg/g,259.7 mg/g and 465.1 mg/g,344.8 mg/g,respectively.SCNCs and NaSCNCs showed high selectivity and interference resistance from coexisting ions for the adsorption of Pb 2+.NaSCNCs could be efficiently regenerated with a mild saturated NaCl solution with no loss of capacity after two recycles.The adsorption mechanisms of SCNCs and NaSCNCs were discussed. | Xiaolin Yu Shengrui Tong Maofa Ge Lingyan Wu Junchao Zuo Changyan Cao Weiguo Song | 2013 | Journal of Environmental Sciences2013，25，5： | 29 |
| 2 | Single-cell RNA-seq highlights intra-tumoral heterogeneity and malignant progression in pancreatic ductal adenocarcinoma显示文摘Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer featured with high intra-tumoral heterogeneity and poor prognosis. To comprehensively delineate the PDAC intra-tumoral heterogeneity and the underlying mechanism for PDAC progression, we employed single-cell RNA-seq (scRNA-seq) to acquire the transcriptomic atlas of 57,530 individual pancreatic cells from primary PDAC tumors and control pancreases, and identified diverse malignant and stromal cell types, including two ductal subtypes with abnormal and malignant gene expression profiles respectively, in PDAC. We found that the heterogenous malignant subtype was composed of several subpopulations with differential proliferative and migratory potentials. Cell trajectory analysis revealed that components of multiple tumor-related pathways and transcription factors (TFs) were differentially expressed along PDAC progression. Furthermore, we found a subset of ductal cells with unique proliferative features were associated with an inactivation state in tumor-infiltrating T cells, providing novel markers for the prediction of antitumor immune response. Together, our findings provide a valuable resource for deciphering the intra-tumoral heterogeneity in PDAC and uncover a connection between tumor intrinsic transcriptional state and T cell activation, suggesting potential biomarkers for anticancer treatment such as targeted therapy and immunotherapy. | Junya Peng Bao-Fa Sun Chuan-Yuan Chen Jia-Yi Zhou Yu-Sheng Chen Hao Chen Lulu Liu Dan Huang Jialin Jiang Guan-Shen Cui Ying Yang Wenze Wang Dan Guo Menghua Dai Junchao Guo Taiping Zhang Quan Liao Yi Liu Yong-Liang Zhao Da-Li Han Yupei Zhao Yun-Gui Yang Wenming Wu | 2019 | Cell Research2019，29，9： | 24 |
| 3 | Matching mechanism analysis on an adaptive cycle engine显示文摘As a novel aero-engine concept,adaptive cycle aero-engines(ACEs) are attracting wide attention in the international aviation industry due to their potential superior task adaptability along a wide flight regime.However,this superior task adaptability can only be demonstrated through proper combined engine control schedule design.It has resulted in an urgent need to investigate the effect of each variable geometry modulation on engine performance and stability.Thus,the aim of this paper is to predict and discuss the effect of each variable geometry modulation on the matching relationship between engine components as well as the overall engine performance at different operating modes,on the basis of a newly developed nonlinear component-based ACE performance model.Results show that at all four working modes,turning down the high pressure compressor variable stator vane,the low pressure turbine variable nozzle,the nozzle throat area,and turning up the core-driven fan stage variable stator vane,the high pressure turbine variable nozzle can increase the thrust at the expense of a higher high pressure turbine inlet total temperature.However,the influences of these adjustments on the trends of various engine components' working points and working lines as well as the ratio of the rotation speed difference are different from each other.The above results provide valuable guidance and advice for engine combined control schedule design. | Zheng Junchao Chen Min Tang Hailong | 2017 | Chinese Journal of Aeronautics2017，30，2： | 14 |

| 6 | Synergistic effects of biochar/microbial inoculation on the enhancement of pig manure composting显示文摘With the aim to comparatively investigate the effect of the addition of additives such as biochar(BC),microbial inoculation(MI)and biochar/microbial inoculation(BCMI)on composting enhancement,nitrogen conservation,greenhouse gas emissions,the quality improvement of pig manure compost were comparatively investigated in a 42-day aerobic pig manure composting experiment.The results showed that the duration of the thermophilic stage,the degradation of organic matter and the detoxification of the compost were enhanced in the BC,MI and BCMI treatments compared with those in the control(without additive).Moreover,the content of total Kjeldahl nitrogen in the BC,MI and BCMI treatments was increased by 38.1,48.9 and 59.0%,respectively,through the reduction of NH_(3) volatilization and N_(2)O production,which were higher than those of the control(31.8%).A reduction in CH_(4) release during composting was not observed with the MI and BCMI treatments.Following 42 days of composting,the final product of the three treatments exhibited acceptable potential for use as a fertilizer in agriculture;the BCMI treatment showed an especially synergistic effect on pig manure composting enhancement. | Zhineng Tu Xiuna Ren Junchao Zhao Sanjeev Kumar Awasthi Quan Wang Mukesh Kumar Awasthi Zengqiang Zhang Ronghua Li | 2019 | Biochar2019，1，1： | 8 |
| 7 | Experimental Investigation on Noise of Cavitation Nozzle and Its Chaotic Behaviour显示文摘The researches of cavitation noise mainly focus on the incipiency and developing of cavitation to prevent the cavititation erosion in the hydraulic machinery, while there is few report about the collapse strength of cavitation bubbles produced by water jet through the cavitation nozzle to utilize efficiently the collapse energy of cavitation bubbles. The cavitation noise signals are collected with hydrophones for the cavitation nozzle and general nozzle at the target position and the nozzle exit separately in the conditions of different standoff distance. The features of signal's frequency spectrum and power spectrum are analyzed for various nozzles by way of classical methods. Meanwhile, based on chaotic theory, phase space reconstruction is processed and the maximum Lyapunov index is calculated separately for each cavitation signal's time series. The results of chaotic analysis are compared with the one of conventional analysis. The analyzed data show that there are the marked differences at the spectrum between the cavitation nozzle and general nozzle at the target position while the standoff distance is 35 mm, which mainly displays at the high frequency segment (60-120 kHz). The maximum Lyapunov index calculated appear at standoff distance 35 mm, which is an optimum standoff distance for the most bubbles to collapse at the target. At the nozzle exit, the noise signal of cavitation nozzle is different from the general nozzle, which also displays at the high frequency segment. The results demonstrate that the water jet modulated by the cavitation nozzle can produce effectually cavitation, and at the target position the amplitude and energy of noise spectrum in high frequency segment for cavitation nozzle are higher than conventional nozzle and the Lyapunov index of cavitation nozzle is larger than conventional nozzle as the standoff distance is less than 55 mm. The proposed research reveals that the cavitation noise produced by collapse of cavitation bubbles attributes mainly to the high frequency segment of the spectrum, which provides references for the research on cavitation noise. | ZHANG Fenghua LIU Haifeng XU Junchao TANG Chuanlin | 2013 | Chinese Journal of Mechanical Engineering2013，26，4： | 8 |
| 8 | Development of mouse preimplantation embryos in space显示文摘The development o f life beyond planet Earth is a long-standing quest of the human race,but whether normal mammalian embryonic development can occur in space is still unclear.Here,we show unequivocally that preimplantation mouse embryos can develop in space;but the rate of blastocyst formation and blastocyst quality are compromised.Additionally,the cells in the embryo contain severe DNA damage,while the genome of the blastocysts developed in space is globally hypomethylated with a unique set of differentially methylated regions.The developmental defects,DNA damage and epigenetic abnormalities can be largely mimicked by the treatment with ground-based low-dose radiation.However,the exposure to simulated microgravity alone does not cause major disruptions of embryonic development,indicating that radiation is the main cause for the developmental defects.This work advances the understanding of embryonic development in space and reveals long-term extreme low-dose radiation as a hazardous factor for mammalian reproduction. | Xiaohua Lei Yujing Cao Baohua Ma Yunfang Zhang Lina Ning Jingjing Qian Liwen Zhang Yongcun Qu Tao Zhang Dehong Li Qi Chen Junchao Shi Xudong Zhang Chiyuan Ma Ying Zhang Enkui Duan | 2020 | National Science Review2020，7，9： | 8 |

| 10 | Fabrication of highly efficient heterostructured Ag-CeO2/g-C3N4 hybrid photocatalyst with enhanced visible-light photocatalytic activity显示文摘On the basis of hydrothermal synthesis of Ag-CeO2 microspheres,Ag-CeO2/g-C3N4 composite photocatalyst with heterostructure was prepared by simple solvent evaporation of Ag-CeO2 and g-C3N4.To characterize the composition,structure,morphology and light absorption properties of the as-prepared Ag-CeO2/g-C3N4 composites,XRD,FTIR XPS,SEM,TEM,PL,BET and UV-vis DRS were used,respectively.The as-prepared photocatalyst was subjected to photocatalytic degradation of pollutants,and the prepared composite material has excellent photocatalytic activity for photodegradation of methylene blue(MB).The research shows that the photocatalytic properties of Ag-CeO2/g-C3N4 composites were related to the mass ratio of Ag-CeO2 microspheres and g-C3N4 nanosheets.When the ratio of Ag-CeO2 microspheres:g-C3N4 is 1:5,the composites have the highest photocatalytic activity,which was 9.6 and 3.3 times that of single Ag-CeO2 and g-C3N4,respectively.The improvement of photocatalytic activity is attributed to the heterostructure between the composite materials and the addition of noble metal silver,and the degradation of methylene blue by the visible light irradiation material is greatly improved.Finally,an attempt was made to analyze the principle of photocatalytic degradation of pollutants in prepared materials. | Chengbao Liu Dongxing Mao Jian Pan Junchao Qian Wenya Zhang Feng Chen Zhigang Chen Yenan Song | 2019 | Journal of Rare Earths2019，37，12： | 7 |

| 13 | SPORTS1.0: A Tool for Annotating and Profiling Non-coding RNAs Optimized for rRNA-and tRNA-derived Small RNAs显示文摘High-throughput RNA-seq has revolutionized the process of small RNA(sRNA) discovery, leading to a rapid expansion of s RNA categories. In addition to the previously wellcharacterized sRNAs such as micro RNAs(mi RNAs), piwi-interacting RNAs(piRNAs), and small nucleolar RNA(sno RNAs), recent emerging studies have spotlighted on t RNA-derived s RNAs(tsRNAs) and rRNA-derived s RNAs(rs RNAs) as new categories of s RNAs that bear versatile functions. Since existing software and pipelines for sRNA annotation are mostly focused on analyzing mi RNAs or pi RNAs, here we developed the sRNA annotation pipeline optimized for rRNA-and tRNA-derived sRNAs(SPORTS1.0). SPORTS1.0 is optimized for analyzing ts RNAs and rsRNAs from sRNA-seq data, in addition to its capacity to annotate canonical sRNAs such as mi RNAs and pi RNAs. Moreover, SPORTS1.0 can predict potential RNA modification sites based on nucleotide mismatches within sRNAs. SPORTS1.0 is precompiled to annotate s RNAs for a wide range of 68 species across bacteria, yeast, plant, and animal kingdoms, while additional species for analyses could be readily expanded upon end users' input. For demonstration, by analyzing sRNA datasets using SPORTS1.0, we reveal that distinct signatures are present in tsRNAs and rsRNAs from different mouse cell types. We also find that compared to other s RNA species, tsRNAs bear the highest mismatch rate, which is consistent with their highly modified nature. SPORTS1.0 is an opensource software and can be publically accessed at http://gffzz188fe103f8f1460as5qvo69f9pw0k6990.ffgz.tsg.suse.edu.cn/junchaoshi/sports1.0. | Junchao Shi Eun-A Ko Kenton M.Sanders Qi Chen Tong Zhou | 2018 | Genomics, Proteomics & Bioinformatics2018，16，2： | 6 |

| 15 | Metformin inhibits pancreatic cancer metastasis caused by SMAD4 deficiency and consequent HNF4G upregulation显示文摘Pancreatic ductal adenocarcinoma(PDAC)has poor prognosis due to limited therapeutic options.This study examines the roles of genome-wide association study identified PDAC-associated genes as therapeutic targets.We have identified HNF4G gene whose silencing most effectively repressed PDAC cell invasiveness.HNF4G overexpression is induced by the deficiency of transcriptional factor and tumor suppressor SMAD4.Increased HNF4G are correlated with SMAD4 deficiency in PDAC tumor samples and associated with metastasis and poor survival time in xenograft animal model and in patients with PDAC(log-rank P=0.036;HR=1.60,95%CI=1.03–2.47).We have found that Metformin suppresses HNF4G activity via AMPK-mediated phosphorylation-coupled ubiquitination degradation and inhibits in vitro invasion and in vivo metastasis of PDAC cells with SMAD4 deficiency.Furthermore,Metformin treatment significantly improve clinical outcomes and survival in patients with SMAD4-deficient PDAC(log-rank P=0.022;HR=0.31,95%CI=0.14–0.68)but not in patients with SMAD4-normal PDAC.Pathway analysis shows that HNF4G may act in PDAC through the cell-cell junction pathway.These results indicate that SMAD4 deficiency-induced overexpression of HNF4G plays a critical oncogenic role in PDAC progression and metastasis but may form a druggable target for Metformin treatment. | Chengcheng Wang Taiping Zhang Quan Liao Menghua Dai Junchao Guo Xinyu Yang Wen Tan Dongxin Lin Chen Wu Yupei Zhao | 2021 | Protein & Cell2021，12，2： | 5 |
| 16 | Porphyromonas gingivalis exacerbates ulcerative colitis via Porphyromonas gingivalis peptidylarginine deiminase显示文摘Abstract:Ulcerative Colitis(UC)has been reported to be related to Porphyromonas gingivalis(P.gingivalis).Porphyromonas gingivalis peptidylarginine deiminase(PPAD),a virulence factor released by P.gingivalis,is known to induce inflammatory responses.To explore the pathological relationships between PPAD and UC,we used homologous recombination technology to construct a P.gingivalis strain in which the PPAD gene was deleted(Δppad)and aΔppad strain in which the PPAD gene was restored(comΔppad).C57 BL/6 mice were orally gavaged with saline,P.gingivalis,Δppad,or comΔppad twice a week for the entire 40 days(days 0-40),and then,UC was induced by dextran sodium sulfate(DSS)solution for 10 days(days 31-40).P.gingivalis and comΔppad exacerbated DDS-induced colitis,which was determined by assessing the parameters of colon length,disease activity index,and histological activity index,butΔppad failed to exacerbate DDS-induced colitis.Flow cytometry and ELISA revealed that compared withΔppad,P.gingivalis,and comΔppad increased T helper 17(Th17)cell numbers and interleukin(IL)-17 production but decreased regulatory T cells(Tregs)numbers and IL-10 production in the spleens of mice with UC.We also cocultured P.gingivalis,Δppad,or comΔppad with T lymphocytes in vitro and found that P.gingivalis and comΔppad significantly increased Th17 cell numbers and decreased Treg cell numbers.Immunofluorescence staining of colon tissue paraffin sections also confirmed these results.The results suggested that P.gingivalis exacerbated the severity of UC in part via PPAD. | Xida Zhao Jingbo Liu Chong Zhang Ning Yu Ze Lu Shuwei Zhang Yuchao Li Qian Li Junchao Liu Dongjuan Liu Yaping Pan | 2021 | International Journal of Oral Science2021，13，3： | 5 |
| 17 | Suppress voltage decay of lithium-rich materials by coating layers with different crystalline states显示文摘Li-rich oxides are considered as the most commercial potential cathode materials due to the high theoretical specific discharge capacity. Here, ZrO_(2) in different crystalline states are applied as the coating layers to enhance the electrochemical performance of hollow Li[Li_(0.2)Mn_(0.54)Ni_(0.13)Co_(0.13)]O_(2) materials.Meanwhile, a series of characterizations(XRD, SEM, TEM, EDX etc.) are conducted to compare the effects of ZrO_(2) coating layer with different crystalline states on the host material. The results elucidate that the Li-rich Mn-based material with the polycrystal ZrO_(2) coating layer has a slight advantage in rate performance, while the host material with the single crystal ZrO_(2)-coating layer has a better cycling performance and effectively suppresses voltage decay with the effect of excellently inhibiting layered to spinel-like phase transition and metal dissolution during charging and discharging process. | Zhiwei Zhou Ziyan Luo Zhenjiang He Junchao Zheng Yunjiao Li Cheng Yan Jing Mao | 2021 | Journal of Energy Chemistry2021，30，9： | 4 |
| 18 | A protocol for structured illumination microscopy with minimal reconstruction artifacts显示文摘The imaging rate of structured illumination microscopy (SIM) reached 188 Hz recently. As the exposure time decreases, the camera detects fewer virtual photons, while the noise level remains the same. As a result, the signal-to-noise ratio (SNR) decreases sharply. Furthermore, the SNR decreases further because of photobleaching and phototoxicity. This decreased quality of SIM raw data may lead to surprising artifacts with various causes, which may confuse a new user of SIM microscopy. We summarize three significant possible sources of severe artifacts in reconstructed super-resolution (SR) images. Ultrafast motion of a biological sample or an uneven illumination pattern is the most difficult to be identified. The estimated parameter could also be incorrect, leading to artifact of regular patterns. Furthermore, rec on struction with the Wiener method generates stochastic artifacts due to the amplification of noise during the deconvolution process. To deal with these problems, we have established a protocol to reconstruct ultrafast SIM raw data obtained in low SNR conditions. First, we checked the quality of the raw data with the ImageJ plugin SIMcheck before rec on struction. Then, a modified parameter estimation method was used to improve the precision of the parameters. Finally, an iterative algorithm was used for SIM reconstruction under low signal-to-noise ratio cond让ions. This procedure effectively suppressed the artifacts in the super-resoluti on images rec on structed from raw data of low signal-to-noise ratio. | Junchao Fan Xiaoshuai Huang Liuju Li Shan Tan Liangyi Chen | 2019 | Biophysics Reports2019，5，2： | 4 |

For some interesting solutions, the figures are given out to show their properties. | Xiangpeng XIN Junchao CHEN Yong CHEN | 2014 | Chinese Annals of Mathematics,Series B2014，35，6： | 4 |
| 20 | Hollow cobalt oxide nanoparticles embedded in nitrogen-doped carbon nanosheets as an efficient bifunctional catalyst for Zn–air battery显示文摘Rational design of low-cost, highly electrocatalytic activity, and stable bifunctional electrocatalysts for oxygen reduction reaction(ORR) and oxygen evolution reaction(OER) has been a great significant for metal–air batteries. Herein, an efficient bifunctional electrocatalyst based on hollow cobalt oxide nanoparticles embedded in nitrogen-doped carbon nanosheets(Co/N-Pg) is fabricated for Zn–air batteries. A lowcost biomass peach gum, consisting of carbon, oxygen, and hydrogen without other heteroatoms, was used as carbon source to form carbon matrix hosting hollow cobalt oxide nanoparticles. Meanwhile, the melamine was applied as nitrogen source and template precursor, which can convert to carbon-based template graphitic carbon nitride by polycondensation process. Owing to the unique structure and synergistic effect between hollow cobalt oxide nanoparticles and Co-N-C species, the proposal Co/N-Pg catalyst displays not only prominent bifunctional electrocatalytic activities for ORR and OER, but also excellent durability. Remarkably, the assembled Zn–air battery with Co/N-Pg air electrode exhibited a low discharge-charge voltage gap(0.81 V at 50 mA cm^-2) and high peak power density(119 mW cm^-2) with long-term cycling stability. This work presents an effective approach for engineering transition metal oxides and nitrogen modified carbon nanosheets to boost the performance of bifunctional electrocatalysts for Zn–air battery. | Yuhui Tian Li Xu Jian Bao Junchao Qian Huaneng Su Huaming Li Haidong Gu Cheng Yan Henan Li | 2019 | Journal of Energy Chemistry2019，28，6： | 4 |
