| 1 | Single-cell transcriptome analysis of the novel coronavirus (SARS-CoV-2) associated gene ACE2 expression in normal and non-obstructive azoospermia (NOA) human male testes显示文摘Being infected by SARS-CoV-2 may cause damage to multiple organs in patients, such as the lung, liver and heart. Angiotensin-converting enzyme 2(ACE2), reported as a SARS-CoV-2 receptor, is also expressed in human male testes. This suggests a potential risk in human male reproductive system. However, the characteristics of ACE2-positive cells and the expression of other SARS-CoV-2 process-related genes are still worthy of further investigation. Here, we performed singlecell RNA seq(scRNA-seq) analysis on 853 male embryo primordial germ cells(PGCs) and 2,854 normal testis cells to assess the effects of the SARS-CoV-2 virus on the male reproductive system from embryonic stage to adulthood. We also collected and constructed the scRNA-seq library on 228 Sertoli cells from three non-obstructive azoospermia(NOA) patients to assess the effects at disease state. We found that ACE2 expressing cells existed in almost all testis cell types and Sertoli cells had highest expression level and positive cells ratio. Moreover, ACE2 was also expressed in human male PGCs. In adulthood, the level of ACE2 expression decreased with the increase of age. We also found that ACE2 positive cells had high expressions of stress response and immune activation-related genes. Interestingly, some potential SARS-CoV-2 process-related genes such as TMPRSS2, BSG, CTSL and CTSB had different expression patterns in the same cell type. Furthermore, ACE2 expression level in NOA donors’ Sertoli cells was significantly decreased. Our work would help to assess the risk of SARS-CoV-2 infection in the male reproductive system. | Xixi Liu Yidong Chen Wenhao Tang Li Zhang Wei Chen Zhiqiang Yan Peng Yuan Ming Yang Siming Kong Liying Yan Jie Qiao | 2020 | Science China(Life Sciences)2020，63，7： | 14 |
| 2 | Hydrogen evolution and electromigration in the corrosion of aluminium metal sheath inside high‐voltage cables显示文摘The urgent need for power transmission is the reason for leading research on the safer operation of high‐voltage cables.These high‐voltage cables are emerging as an efficient technology for underground power transmission.However,the electrochemical corrosion of aluminium(Al)metal sheaths in these cables is a common and challenging degradation process.Herein,the corrosion mechanisms and electrochemical analysis are investigated by using scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR),electrochemical impedance spectroscopy(EIS)and laboratory‐designed electro-chemical characterisation techniques.In the corrosion experiments,the authors evaluated the corrosion rate by measuring the release rate of hydrogen gas and explored the different roles of sodium polyacrylate(NaPA)during the corrosion process.It is found that the complexation reactions between NaPA and Al inhibited corrosion while increased the resistance of the buffer layer.The proposed mechanisms of corrosion in this study can improve the lifespan and sustainability of high‐voltage power transmission. | Yidong Chen Kai Zhou Jiamin Kong Shakeel Akram Xiancheng Ren Xiaoshan Zhang Yuan Li Qi Zhao | 2022 | High Voltage2022，7，2： | 7 |
| 3 | Hybrid waveguide scheme for silicon-based quantum photonic circuits with quantum light sources显示文摘We propose a hybrid silicon waveguide scheme to avoid the impact of noise photons induced by pump lights in application scenarios of quantum photonic circuits with quantum light sources.The scheme is composed of strip waveguide and shallow-ridge waveguide structures.It utilizes the difference of biphoton spectra generated by spontaneous four-wave mixing(SFWM)in these two waveguides.By proper pumping setting and signal/idler wavelength selection,the generation of desired photon pairs is confined in the strip waveguide.The impact of noise photons generated by SFWM in the shallow-ridge waveguide can be avoided.Hence,the shallowridge waveguide could be used to realize various linear operation devices for pump light and quantum state manipulations.The feasibility of this scheme is verified by theoretical analysis and a primary experiment.Two applications are proposed and analyzed,showing its great potential in silicon-based quantum photonic circuits. | LINGJIE YU CHENZHI YUAN RENDUO QI YIDONG HUANG WEI ZHANG | 2020 | Photonics Research2020，8，3： | 3 |
| 4 | High-efficient generation algorithm for large random active shield显示文摘Dear editor,Security integrated circuits play important roles in trusted platform modules[1],embedded devices,etc.However,invasive attacks[2]are serious threats on such circuits.Active shield is regard('d as an effective method against invasive attacks.Active shield is a mesh of dense metal wires covering the surface of an integrated circuit(IC)[3].The security level of IC increases with the geometric difficulty of the mesh.The active shield proposed in[4,5]has a complex geonietry based on random Hamiltonian path.Given this randomness,it is difficult to recognize the geometry of the shield.However,the available generation algorithms are agonizingly slow. | Ruishan XIN Yidong YUAN Jiaji HE Yuehui LI Yiqiang ZHAO | 2019 | Science China(Information Sciences)2019，62，3： | 2 |
| 5 | Specific biotests to assess eco-toxicity of biodegradable polymer materials in soil显示文摘Eco-toxicity investigation of polymer materials was considered extremely necessary for their potential menace,which was widely use as mulching materials in agricultural.In this study,polyethylene(PE),polystyrene(PS)and synthetic biomaterials-Ecoflex and cellulose were applying into soil cultivated with two potential indicator plants species:oat(A v ena sati v a)and red radish(Raphanus sativum).Variety of chemical,biochemical parameters and enzyme activity in soil were proved as effective approach to evaluate polymers phytotoxicity in plant-soil mesocosm.The F-value of biomass,pH,heavy metal and electoral conductivity of Raphanus behaved significant different from T0.Significant analysis results indicated biodegradation was fast in PE than PS,besides,heavy metals were dramatically decrease in the end implied the plant absorption may help decrease heavy metal toxicity.The increase value at T2 of Dehydrogenase activity(0.84 higher than average value for Avena&0.91 higher for Raphanus),Metabolic Index(3.12 higher than average value for Avena&3.81 higher for Raphanus)means during soil enzyme activity was promoted by biodegradation for its heterotrophic organisms’energy transportation was stimulated.Statistics analysis was carried on Biplot PC1(24.2%of the total variance),PC2(23.2%of the total variance),versus PC3(22.8%of the total variance),which indicated phosphatase activity and metabolic index was significant correlated,and high correlation of ammonium and protease activity.Furthermore,the effects were more evident in Raphanus treatments than in Avena,suggesting the higher sensitivity of Raphanus to polymers treatment,which indicate biodegradation of polymers in Raphanus treatment has produced intermediate phytotoxic compounds. | Haiyan Chen Fei Wang Huilun Chen HongDa Fang Weiying Feng Yuan Wei FanFan Wang HaiLei Su YiDong Mi Min Zhou XinRu Li Serena Doni Andrea Corti | 2021 | Journal of Environmental Sciences2021，33，7： | 2 |

| 8 | Applications of atomic force microscopy in immunology显示文摘Cellular mechanics,a major regulating factor of cellular architecture and biological functions,responds to intrinsic stresses and extrinsic forces exerted by other cells and the extracellular matrix in the microenvironment.Cellular mechanics also acts as a fundamental mediator in complicated immune responses,such as cell migration,immune cell activation,and pathogen clearance.The principle of atomic force microscopy(AFM)and its three running modes are introduced for the mechanical characterization of living cells.The peak force tapping mode provides the most delicate and desirable virtues to collect high-resolution images of morphology and force curves.For a concrete description of AFM capabilities,three AFM applications are discussed.These applications include the dynamic progress of a neutrophil-extracellular-trap release by neutrophils,the immunological functions of macrophages,and the membrane pore formation mediated by perforin,streptolysin O,gasdermin D,or membrane attack complex. | Jiping Li Yuying Liu Yidong Yuan Bo Huang | 2021 | Frontiers of Medicine2021，15，1： | 1 |

| 11 | Gas in place and its controlling factors of deep shale of the Wufeng–Longmaxi Formations in the Dingshan area, Sichuan Basin显示文摘Recently, deeply-buried shale (depth > 3500 m) has become an attractive target for shale gas exploration and development in China. Gas-in-place (GIP) is critical to shale gas evaluation, but the GIP content of deep shale and its controlling factors have rarely been investigated. To clarify this issue, an integrated investigation of deep gas shale (3740–3820 m depth) of the Lower Paleozoic Wufeng–Longmaxi Formations (WF–LMX) in the Dingshan area, Sichuan Basin had been carried out. Our results show that the GIP content of the studied WF–LMX shale in the Dingshan area ranges from 0.85 to 12.7 m^(3)/t, with an average of 3.5 m^(3)/t. Various types of pores, including organic matter (OM) pore and inorganic pore, are widely developed in the deep shale, with total porosity of 2.2 to 7.3% (average = 4.5%). The OM pore and clay-hosted pore are the dominant pore types of siliceous shale and clay-rich shale, respectively. Authigenic quartz plays a critical role in the protection of organic pores in organic-rich shales from compaction. The TOC content controls the porosity of shale samples, which is the major factor controlling the GIP content of the deep shale. Clay minerals generally play a negative role in the GIP content. In the Sichuan Basin, the deep and ultra-deep WF–LMX shales display the relatively high porosity and GIP contents probably due to the widespread of organic pores and better preservation, revealing great potentials of deep and ultra-deep shale gas. From the perspective of rock mechanical properties, deep shale is the favorable exploration target in the Sichuan Basin at present. However, ultra-deep shale is also a potential exploration target although there remain great challenges. | Ping GAO Xianming XIAO Dongfeng HU Ruobing LIU Fei LI Qin ZHOU Yidong CAI Tao YUAN Guangming MENG | 2023 | Frontiers of Earth Science2023，17，1： | 0 |
| 12 | Morphology evolution and breakdown mechanism of cross-linked polyethylene(XLPE)-silicone rubber(SiR)interface induced by silicone grease diffusion显示文摘Silicone grease(SG)is used for lubrication during cable accessory installation and can penetrate into the silicone rubber(SiR),leading to properties deterioration of the SiR.In this study,the effects of SG on the breakdown characteristics of the cross-linked poly-ethylene(XLPE)-SiR interface are investigated.First,the variation of the XLPE-SiR interface breakdown voltage with SG coating time is experimentally explored.The interface breakdown voltage significantly increases after SG is applied,remains stable for coating times of up to approximately 144 h and then rapidly decreases;the minimum interface breakdown voltage is lower than that without the SG coating.Next,the effects of SG on the chemical composition and surface topography of the SiR are examined by infrared spectroscopy and optical profilometry,respectively.The SG penetration does not change the functional groups of the SiR but significantly increases its surface roughness.Finally,the interface electric-field distribution after coating with SG is analysed by finite-element simulation,revealing that the residual SG at the interface distorts the interface electric field after a long coating time.The increase in the SiR surface roughness caused by SG diffusion and the interface electric-field distortion caused by the residual SG together lead to the decrease of the interface breakdown voltage. | Zerui Li Kai Zhou Pengfei Meng Hao Yuan Zikang Wang Yidong Chen Yuan Li Guangya Zhu | 2022 | High Voltage2022，7，4： | 0 |

| 14 | Gadolinium-doped mesoporous tungsten oxides:Rational synthesis,gas sensing performance,and mechanism investigation显示文摘As a typical family of volatile toxic compounds,benzene derivatives are massive emission in industrial production and the automobile field,causing serious threat to human and environment.The reliable and convenient detection of low concentration benzene derivatives based on intelligent gas sensor is urgent and of great significance for environmental protection.Herein,through heteroatomic doping engineering,rare-earth gadolinium(Gd)doped mesoporous WO_(3)with uniform mesopores(15.7–18.1 nm),tunable high specific surface area(52–55 m^(2)·g^(−1)),customized crystalline pore walls,was designed and utilized to fabricate highly sensitive gas sensors toward benzene derivatives,such as ethylbenzene.Thanks to the high-density oxygen vacancies(OV)and significantly increased defects(W^(5+))produced by Gd atoms doping into the lattice of WO_(3)octahedron,Gd-doped mesoporous WO_(3)exhibited excellent ethylbenzene sensing performance,including high response(237 vs.50 ppm),rapid response–recovery dynamic(13 s/25 s vs.50 ppm),extremely low theoretical detection limit of 24 ppb.The in-situ diffuse reflectance infrared Fourier transform and gas chromatograph-mass spectrometry results revealed the gas sensing process underwent a catalytic oxidation conversion of ethylbenzene into alcohol species,benzaldehyde,acetophenone,and carboxylate species along with the resistance change of the Gd-doped mesoporous WO_(3)based sensor.Moreover,a portable smart gas sensing module was fabricated and demonstrated for real-time detecting ethylbenzene,which provided new ideas to design heteroatom doped mesoporous materials for intelligent sensors. | Yanyan Li Keyu Chen Yan Liu Junhao Ma Yaozu Liao Haitao Yang Jinsheng Cheng Qin Yue Kaiping Yuan Yuan Ren Yidong Zou Yonghui Deng | 2023 | Nano Research2023，16，5： | 0 |
