| 1 | Influence of grain size on the small fatigue crack initiation and propagation behaviors of a nickel-based superalloy at 650℃显示文摘GH4169 at 650℃ in atmosphere was investigated by using single edge notch tensile specimens. The number of main cracks and crack initiation mechanisms at the notch surface strongly depended on the grain size. The crack initiation life accounted for more percentages of the total fatigue life for the alloy with smaller grain size. The fatigue life generally increased with increasing crack initiation life. The small crack transited to long crack when its length reached 10 times the grain size. | Xumin Zhu Congyang Gong Yun-Fei Jia Runzi Wang Chengcheng Zhang Yao Fu Shan-Tung Tu Xian-Cheng Zhang | 2019 | Journal of Materials Science & Technology2019，35，8： | 9 |
| 2 | Peripheral CD4^(+) T cell signatures in predicting the responses to anti-PD-1/PD-L1 monotherapy for Chinese advanced non-small cell lung cancer显示文摘Limited benefit population of immune checkpoint inhibitors makes it urgent to screen predictive biomarkers for stratifying the patients.Herein,we have investigated peripheral CD4^(+) T cell signatures in advanced non-small cell lung cancer(NSCLC)patients receiving anti-PD-1/PD-L1 treatments.It was found that the percentages of IFN-γand IL-17A secreting naïve CD4^(+) T cells(Tn),and memory CD4^(+) T cells(Tm)expressing PD-1,PD-L1 and CTLA-4 were significantly higher in responder(R)than non-responder(NonR)NSCLC patients associated with a longer progression free survival(PFS).Logistic regression analysis revealed that the baseline IFN-γ-producing CD4^(+) Tn cells and PD-1^(+)CD4^(+) Tm cells were the most significant signatures with the area under curve(AUC)value reaching 0.849.This was further validated in another anti-PD-1 monotherapy cohort.Conversely,high percentage of CTLA-4^(+)CD4^(+) Tm cells was associated with a shorter PFS in patients receiving anti-PD-L1 monotherapy.Our study therefore elucidates the significance of functional CD4^(+) Tn and Tm subpopulations before the treatment in predicting the responses to anti-PD-1 treatment in Chinese NSCLC patients.The fact that there display distinct CD4^(+) T cell signatures in the prediction to anti-PD-1 and anti-PD-L1 monotherapy from our study provides preliminary evidence on the feasibility of anti-PD-1 and anti-PD-L1 combination therapy for advanced NSCLC patients. | Liliang Xia Hui Wang Mingjiao Sun Yi Yang Chengcheng Yao Sheng He Huangqi Duan Weimin Xia Ruiming Sun Yaxian Yao Zhiwei Chen Qiong Zhao Hong Li Shun Lu Ying Wang | 2021 | Science China(Life Sciences)2021，64，10： | 7 |
| 3 | Recent advances in electrospun electrode materials for sodium-ion batteries显示文摘Sodium-ion batteries(SIBs)have been considered as an ideal choice for the next generation large-scale energy storage applications owing to the rich sodium resources and the analogous working principle to that of lithium-ion batteries(LIBs).Nevertheless,the larger size and heavier mass of Na^(+)ion than those of Li^(+)ion often lead to sluggish reaction kinetics and inferior cycling life in SIBs compared to the LIB counterparts.The pursuit of promising electrode materials that can accommodate the rapid and stable Na-ion insertion/extraction is the key to promoting the development of SIBs toward a commercial prosperity.One-dimensional(1 D)nanomaterials demonstrate great prospects in boosting the rate and cycling performances because of their large active surface areas,high endurance for deformation stress,short ions diffusion channels,and oriented electrons transfer paths.Electrospinning,as a versatile synthetic technology,features the advantages of controllable preparation,easy operation,and mass production,has been widely applied to fabricate the 1 D nanostructured electrode materials for SIBs.In this review,we comprehensively summarize the recent advances in the sodium-storage cathode and anode materials prepared by electrospinning,discuss the effects of modulating the spinning parameters on the materials’micro/nano-structures,and elucidate the structure-performance correlations of the tailored electrodes.Finally,the future directions to harvest more breakthroughs in electrospun Na-storage materials are pointed out. | Yao Wang Yukun Liu Yongchang Liu Qiuyu Shen Chengcheng Chen Fangyuan Qiu Ping Li Lifang Jiao Xuanhui Qu | 2021 | Journal of Energy Chemistry2021，30，3： | 3 |

| 5 | Plasma Mutation Breeding of High Yield γ-Aminobutyric Acid Lactic Acid Bacteria显示文摘γ-amino butyric acid (GABA) is a non-protein amino acid widely distributed in nature. It has analgesic effect, promotes growth hormone secretion and prevents the physiological function of Alzheimer's disease.In order to improve the yield of GABA, the strain of strain HX-3-6 was tested by Atmospheric and Room Temperature Plasma (ARTP), and the strain with more than 90% lethality was selected for fermentation, and through the gradient plate according to the level of GABA concentration and colony size of the screening. Then, use the fermentation medium for re-screening and genetic stability test. The yield of the mutant strain L-120-1 was 5.828 g/L, which was 18.84% higher than that before the mutation (4.904). The mutant strain L-120-1 was used as the starting strain for ARTP mutagenesis. The yield of the stable mutant strain 90s-high was 6.178g / L, which was 16.15% higher than that before the mutation (5.319g / L). The yield of HX-3-6 strain was higher than that of GABA mutant strain 90s-high 2, which was stable and high yield GABA was 25.98%. | Chengcheng Gao Fan Yang Yao Liu | 2017 | Gene Science & Engineering2017，1，1： | 1 |
| 6 | Two-sided ultrasonic surface rolling process of aeroengine blades based on on-machine noncontact measurement显示文摘As crucial parts of an aeroengine,blades are vulnerable to damage from long-term operation in harsh environments.The ultrasonic surface rolling process(USRP)is a novel surface treatment technique that can highly improve the mechanical behavior of blades.During secondary machining,the nominal blade model cannot be used for secondary machining path generation due to the deviation between the actual and nominal blades.The clamping error of the blade also affects the precision of secondary machining.This study presents a two-sided USRP(TS-USRP)machining for aeroengine blades on the basis of on-machine noncontact measurement.First,a TS-USRP machining system for blade is developed.Second,a 3D scanning system is used to obtain the point cloud of the blade,and a series of point cloud processing steps is performed.A local point cloud automatic extraction algorithm is introduced to extract the point cloud of the strengthened region of the blade.Then,the tool path is designed on the basis of the extracted point cloud.Finally,an experiment is conducted on an actual blade,with results showing that the proposed method is effective and efficient. | Shulei YAO Xian CAO Shuang LIU Congyang GONG Kaiming ZHANG Chengcheng ZHANG Xiancheng ZHANG | 2020 | Frontiers of Mechanical Engineering2020，15，2： | 1 |
| 7 | TPE based aggregation induced emission fluorescent sensors for viscosity of liquid and mechanical properties of hydrogel显示文摘Two amphiphilic TPE E/Z isomers with aggregation induced emission(AIE)property have been synthesized and characterized.The logarithmic fluorescent intensity of the two molecules was in positive relationship with logarithmic viscosity of liquid.To note,the Z-TPE isomer exhibited more sensitivity in the viscosity of liquid sensing in comparison with the corresponding E-TPE counterpart(around 1.80 folds).Furthermore,two molecules could be used as fluorescent sensors for mechanical properties(viscosity and storage modulus)of hydrogel as well.In addition,two sensors displayed low cytotoxicity in normal tissue cell line(L929)within the concentration range of 2–10μmol/L.These results potentially promised their applications as fluorescent sensors for mechanical properties in the fields of biological and biomedical. | Na Wang Hang Yao Qi Tao Jing Sun Hao Ma Yang Wang ChengCheng Zhou Hongying Fan Hongxia Shao Aijian Qin Dawei Su Chenyin Wang Hui Chong | 2022 | Chinese Chemical Letters2022，33，1： | 1 |

| 9 | Improvement of titanium alloy TA19 fatigue life by submerged abrasive waterjet peening:Correlation of its process parameters with surface integrity and fatigue performance显示文摘Submerged abrasive waterjet peening(SAWJP)is an effective anti-fatigue manufacturing technology that is widely used to strengthen aeroengine components.This study investigated the correlation of SAWJP process parameters on surface integrity and fatigue life of titanium alloy TA19.SAWJP with different water pressures and standoff distances(SoDs)was conducted on the TA19 specimens.The surface integrity of the specimens before and after SAWJP with different process parameters was experimentally studied,including microstructure,surface roughness,microhardness,and compressive residual stress(CRS).Finally,fatigue tests of the specimens before and after SAWJP treatment with different process parameters were carried out at room temperature.The results highlighted that the fatigue life of the TA19 specimen can be increased by 5.46,5.98,and 6.28 times under relatively optimal process parameters,which is mainly due to the improved surface integrity of the specimen after SAWJP treatment.However,the fatigue life of specimens treated with improper process parameters is decreased by 0.55 to 0.69 times owing to the terrible surface roughness caused by the material erosion.This work verifies that SAWJP can effectively improve the surface integrity and fatigue life of workpieces,and reveals the relationship between process parameters,surface integrity,and fatigue life,which provides support for the promotion of SAWJP in the manufacturing fields. | Gongyu WANG Shulei YAO Yuxin CHI Chengcheng ZHANG Ning WANG Yalong CHEN Rongsheng LU Zhuang LI Xiancheng ZHANG | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
| 10 | Attack Detection for Spoofed Synchrophasor Measurements Using Segmentation Network显示文摘Synchrophasor measurements are essential to realtime situational awareness of the smart grid but vulnerable to cyber-attacks during the process of transmission and invocation.To ensure data security and mitigate the impact of spoofed synchrophasor measurements,this work proposes a novel object detection method using a Weight-based One-dimensional Convolutional Segmentation Network(WOCSN)with the ability of attack behavior identification and time localization.In WOCSN,automatic data feature extraction can be achieved by onedimensional convolution from the input signal,thereby reducing the impact of handcrafted features.A weight loss function is designed to distribute the contribution for normal and attack signals.Then,attack time is located via the proposed binary method based on pixel segmentation.Furthermore,the actual synchrophasor data collected from four locations are used for the performance evaluation of the WOCSN.Finally,combined with designed evaluation metrics,the time localization ability of WOCSN is validated in the scenarios of composite attacks with different spoofed intensities and time-sensitivities. | Wei Qiu Chengcheng Li Qiu Tang Kaiqi Sun Yilu Liu Wenxuan Yao | 2022 | CSEE Journal of Power and Energy Systems2022，8，5： | 0 |
| 11 | Modification strategies on 2D Ni-Fe MOF-based catalysts in peroxydisulfate activation for efficient organic pollutant removal显示文摘This study reports several modification strategies to optimize and enhance the performance of twodimensional(2D) metal organic frameworks(MOFs)-derived catalysts in peroxydisulfate(PDS) activation.The raw 2D Ni-MOF and 2D Ni-Fe-MOF without modification show poor catalytic activities for PDS activation and high metal ion leaching. The carbonization of 2D MOF can increase the activity of the catalyst but cannot solve the metal leaching problem. The further acid treatment of carbonization products can further improve the catalytic activity and decrease the metal ion leaching. The in-situ growth of2D MOF on graphene oxide(GO) support with subsequent carbonization and acid treatment offers the best performance in PDS activation for organic pollutant removal with low metal ion leaching. Compared with other PDS systems, the Ni-Fe-C-acid/GO system displays much lower catalyst and PDS dosages for p-chloroaniline degradation. This study presents new insights in the modification strategies of 2D MOFbased catalysts in PDS activation. | Minjun Liu Ying Liu Xinru Liu Chengcheng Chu Ducheng Yao Shun Mao | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
