| 1 | Down-regulation of the let-7i facilitates gastric cancer invasion and metastasis by targeting COL1A1显示文摘Dear Editor,Globally,gastric cancer is the most common malignant tumor and the second highest contributor to cancer deaths after lung cancer(Murray et al.,2012).Despite improved success with treatment of early stage gastric cancer(Fuse et al.,2016),the five-year survival rate of advanced staged gastric cancer patients is still low.The aggressive growth characteristics of the tumor and metastasis are key factors responsible for poor overall survival in these patients(Ozkan et al.,2005).Therefore,investigation of the molecular mechanisms that underlie the aggressive behavior of gastric cancers,and identification of potential target genes for therapeutic interventions,is a key imperative. | Yue Shi Zipeng Duan Xun Zhang Xiaotian Zhang Guoqing Wang Fan Li | 2019 | Protein & Cell2019，10，2： | 9 |
| 2 | Pt3Ag alloy wavy nanowires as highly effective electrocatalysts for ethanol oxidation reaction显示文摘Direct ethanol fuel cell(DEFC)has received tremendous research interests because of the more convenient storage and transportation of ethanol vs.compressed hydrogen.However,the electrocatalytic ethanol oxidation reaction typically requires precious metal catalysts and is plagued with relatively high over potential and low mass activity.Here we report the synthesis of Pt3Ag alloy wavy nanowires via a particle attachment mechanism in a facile solvothermal process.Transmission microscopy studies and elemental analyses show highly wavy nanowire structures with an average diameter of 4.6±1.0 nm and uniform Pt3Ag alloy formation.Electrocatalytic studies demonstrate that the resulting alloy nanowires can function as highly effective electrocatalysts for ethanol oxidation reactions(EOR)with ultrahigh specific activity of 28.0 mA/cm^2 and mass activity of 6.1 A/mg,far exceeding that of the commercial Pt/carbon samples(1.10 A/mg).The improved electrocatalytic activity may be partly attributed to partial electron transfer from Ag to Pt in the Pt3Ag alloy,which weakens CO binding and the CO poisoning effect.The one-dimensional nanowire morphology also contributes to favorable charge transport properties that are critical for extracting charge from catalytic active sites to external circuits.The chronoamperometry studies demonstrate considerably improved stability for long term operation compared with the commercial Pt/C samples,making the Pt3Ag wavy nanowires an attractive electrocatalyst for EOR. | Xiaoyang Fu Chengzhang Wan Aixin Zhang Zipeng Zhao Huaixun Huyan Xiaoqing Pan Shuaijing Du Xiangfeng Duan Yu Huang | 2020 | Nano Research2020，13，5： | 5 |

| 4 | Ultrathin wavy Rh nanowires as highly effective electrocatalysts for methanol oxidation reaction with ultrahigh ECSA显示文摘Direct methanol fuel cells (DMFCs) have received tremendous research interests because of the facile storage of liquid methanol vs.hydrogen.However,the DMFC today is severely plagued by the poor kinetics and rather high overpotential in methanol oxidation reaction (MOR).Here we report the investigation of the ultrathin Rh wavy nanowires as a highly effective MOR electrocatalyst.We show that ultrathin wavy Rh nanowires can be robustly synthesized with 2-3 nm diameters.Electrochemical studies show a current peak at the potential of 0.61 V vs.reversible hydrogen electrode (RHE),considerably lower than that of Pt based catalysts (~ 0.8-0.9 V vs.RHE).Importantly,with ultrathin diameters and favorable charge transport,the Rh nanowires catalysts exhibit an ultrahigh electrochemically active surface area determined from CO-stripping (ECSAco) of 144.2 m2/g,far exceeding that of the commercial Rh black samples (20 m2/g).Together,the Rh nanowire catalysts deliver a mass activity of 722 mA/mg at 0.61 V,considerably higher than many previously reported electrocatalysts at the same potential.The chronoamperometry studies also demonstrate good stability and CO-tolerance compared with the Rh black control sample,making ultrathin Rh wavy nanowires an attractive electrocatalyst for MOR. | Xiaoyang Fu Zipeng Zhao Chengzhang Wan Yiliu Wang Zheng Fan Frank Song Bocheng Cao Mufan Li Wang Xue Yu Huang Xiangfeng Duan | 2019 | Nano Research2019，12，1： | 3 |
| 5 | Synthesis of surface controlled nickel/palladium hydride nanodendrites with high performance in benzyl alcohol oxidation显示文摘Benzaldehyde byproduct is an imperative intermediate in the production of fine chemicals and additives.Tuning selectivity to benzaldehyde is therefore critical in alcohol oxidation reactions at the industrial level.Herein,we report a simple but innovative method for the synthesis of palladium hydride and nickel palladium hydride nanodendrites with controllable morphology,high stability,and excellent catalytic activity.The synthesized dendrites can maintain the palladium hydride phase even after their use in the chosen catalytic reaction.Remarkably,the high surface area morphology and unique interaction between nickel-rich surface and palladium hydride (β-phase) of these nanodendrites are translated in an enhanced catalytic activity for benzyl alcohol oxidation reaction.Our Ni/PdH0.43 nanodendrites demonstrated a high selectivity towards benzaldehyde of about 92.0% with a conversion rate of 95.4%,showing higher catalytic selectivity than their PdH0.43 counterparts and commercial Pd/C.The present study opens the door for further exploration of metal/metal-hydride nanostructures as next-generation catalytic materials. | Zipeng Zhao Michelle M.Flores Espinosa Jihan Zhou Wang Xue Xiangfeng Duan Jianwei Miao Yu Huang | 2019 | Nano Research2019，12，6： | 1 |
| 6 | Underwater Noise Target Recognition Based on Sparse Adversarial Co-Training Model with Vertical Line Array显示文摘The automatic identification of underwater noncooperative targets without label records remains an arduous task considering the marine noise interference and the shortage of labeled samples.In particular,the data-driven mechanism of deep learning cannot identify false samples,aggravating the difficulty in noncooperative underwater target recognition.A semi-supervised ensemble framework based on vertical line array fusion and the sparse adversarial co-training algorithm is proposed to identify noncooperative targets effectively.The sound field cross-correlation compression(SCC)feature is developed to reduce noise and computational redundancy.Starting from an incomplete dataset,a joint adversarial autoencoder is constructed to extract the sparse features with source depth sensitivity,aiming to discover the unknown underwater targets.The adversarial prediction label is converted to initialize the joint co-forest,whose evaluation function is optimized by introducing adaptive confidence.The experiments prove the strong denoising performance,low mean square error,and high separability of SCC features.Compared with several state-of-the-art approaches,the numerical results illustrate the superiorities of the proposed method due to feature compression,secondary recognition,and decision fusion. | ZHOU Xingyue YANG Kunde YAN Yonghong LI Zipeng DUAN Shunli | 2023 | Journal of Ocean University of China2023，22，5： | 0 |
