| 1 | Surface acoustic wave humidity sensors based on uniform and thickness controllable graphene oxide thin films formed by surface tension显示文摘Graphene oxide(GO)is a promising candidate for humidity sensing,and the uniformity and thickness of GO films are important for the reproducibility and test signal strength of humidity sensors.In this paper,uniform and thicknesscontrollable GO films are first formed by the surface tension of different concentrations of GO solution and then transferred to surface acoustic wave(SAW)humidity sensors.This GO film formation and transfer process has very good repeatability and stability,as evidenced by the humidity response of the sensors.With the help of the uniform and highly oxidized GO film,the humidity sensors show a significantly high sensitivity(absolute sensitivity of 25.3 kHz/%RH and relative sensitivity of 111.7 p.p.m./%RH)in a wide test range from 10%RH to 90%RH with very little hysteresis(<1%RH).The sensors achieve good reversibility,excellent short-term repeatability and stability.Moreover,the humidity sensors also show a fast response and recovery time of<10 s. | Xianhao Le Yihan Liu Li Peng Jintao Pang Zhen Xu Chao Gao Jin Xie | 2019 | Microsystems & Nanoengineering2019，5，1： | 4 |
| 2 | Design, Synthesis and Insecticidal Activities of Novel 5-Alkoxyfuran-5(H)-one Derivatives显示文摘A series of novel 5?alkoxyfuran-2(5H)-one derivatives was synthesized, and characterized by 1H NMR, 13C NMR and HRMS. Biological activities of all the title compounds were evaluated systematically. Preliminary bioassays indicated that most of the compounds exhibited moderate insecticidal activities against Aphis craccivora and Nilaparvata lugens at 100 mg/L. Compounds 4h and 4w exhibited 100% mortality rate against Aphis craccivora at 100 mg/L, and compound 4h exhibited good mortality rate against Aphis craccivora and Nilaparvata lugens (60% and 75%, respectively) even at 4 mg/L. The results demonstrated the impact of various chemical groups on insecticidal activities and provided a potential clue for further exploring novel high-effective broad-spectrum insecticides. | WANG Xianhao LI Jianguo WANG Guangjian HAN Xianzheng LI Dongmei TIAN Zhongzhen | 2019 | Chemical Research in Chinese Universities2019，35，5： | 3 |
| 3 | Polarization loss analysis and ageing characterisation of transformer oil-immersed insulation by using decoupled frequency domain spectroscopy显示文摘The polarization information contained in the frequency-domain spectroscopy(FDS)could be utilised for characterising the ageing degree of transformer oil-immersed insulation.However,the polarization information will be obscured by its conductance effect,it is thus hard to analyse the polarization behaviour by using the traditional FDS technique.Given this issue,an alternative approach is proposed to analyse the polari-zation information using FDS decoupled by logarithmic-derivative spectroscopy(LDS).Findings proved that the polarization loss information generated by polarization behaviour can be separated from the total dispersion loss.The proposed feature pa-rameters are later used to analyse the polarization loss information under ageing impact.Also,the polarization loss surface is constructed by using these feature parameters to characterise the ageing degrees of oil-immersed samples.Finally,the potential possibility of using the proposed method to analyse the polarization loss and ageing degree are respectively discussed. | Xianhao Fan Jiefeng Liu Yiyi Zhang Zheshi Ding Qingyin Wang | 2022 | High Voltage2022，7，3： | 2 |
| 4 | Recent Advances in Real-Time Analysis of Electrochemical Reactions by Electrochemical Mass Spectrometry显示文摘Electrochemical mass spectrometry(EC-MS)is a powerful tool to capture and analyze the intermediates and products during elec-trochemical reactions.This hyphenated technique combines electrochemistry with mass spectrometry using specific apparatuses,which helps researchers study mechanisms of redox reactions by in situ detecting chemical composition changes.Recently,various EC-MS methods have been applied in a series of electrochemical reactions to reveal the mechanisms,mainly in the areas of electro-chemical sensors,organic electrochemistry,and electrocatalysis.In this review,we intend to summarize the recent advances in re-al-time analysis of different types of electrochemical reactions by EC-MS and offer an outlook on the perspectives in these areas. | Xianhao Zhang Jirui Zhan Zhengyou Yu Jintao Deng Meixian Li Yuanhua Shao | 2023 | Chinese Journal of Chemistry2023，41，2： | 2 |

| 6 | Donkey pericardium as a select sourcing to manufacture percutaneous heart valves:Decellularization has not yet demonstrated any clear cut advantage to glutaraldehyde treatment显示文摘Background:The donkey pericardium is considered a good candidate to manufacture percutaneous heart valves based upon its thinness,low cellularity and undulating collagen bundles and laminates.Decellularization represents an avenue worth exploring,should its superiority to glutaraldehyde-treated pericardium be demonstrated.Materials and methods:Donkey pericardium was divided into two groups:regular glutaraldehyde fixation and mild decellularization.The treated pericardia were observed using scanning electron microscopy,histology and transmission electron microscopy.Tensile tests were performed along the axial and perpendicular directions,with the data fitted into both the Gasser–Ogden–Holzapfel(GOH)material model and the Fung’s anisotropic one.Results:The microstructures of the pericardia processed by the two protocols were similar,showing collagen bundles and laminates free of flaws.The decellularization eliminated most of the cells,however leaving the structure somehow compressed.The collagen filaments in bundles were slightly blurry.The anisotropy rates of the non-decellularized specimens were almost identical to the decellularized ones.The decellularized pericardium appeared stiffer.Conclusion:The decellularization proved to be effective.However,it makes the tissue stiffer,which may lead to higher shear concentration during cardiac cycles and reduce its wavy microstructure.Therefore,it appears premature to select decellularized donkey pericardium to manufacture heart valves. | Aisa Rassoli Yiming Li Xianhao Bao Fabien Kawecki Xinzhe Zhao Daniel Chappard Gaetan Le-Bel Jiaxuan Feng Benedikt Weber Nasser Fatouraee Ze Zhang Zaiping Jing Lucie Germain Lu Wang Robert Guidoin | 2019 | Medicine in Novel Technology and Devices2019，，4： | 1 |

| 8 | Rho 1 participates in parasitoid wasp eggs maturation and host cellular immunity inhibition显示文摘Endoparasitoid wasps introduce venom into their host insects during the egglaying stage.Venom proteins play various roles in the host physiology,development,immunity,and behavior manipulation and regulation.In this study,we identified a venom protein,MmRhol,a small guanine nucleotide-binding protein derived from ovary in the endoparasitoid wasp Microplitis mediator and found that knockdown of its expression by RNA interference caused down-regulation of vitellogenin and juvenile hormone,egg production,and cocoons formation in the female wasps.We demonstrated that MmRho1 entered the cotton bollworm's(host)hemocytes and suppressed cellular immune responses after parasitism using immunofluorescence staining.Furthermore,wasp MmRhol interacted with the cotton bollworm's actin cytoskeleton rearrangement regulator diaphanous by yeast 2-hybrid and glutathione s-transferase pull-down.In conclusion,this study indicates that MmRho1 plays dual roles in wasp development and the suppression of the host insect cellular immune responses. | Ruijuan Wang Zhe Lin Lizhen Zhou Caihua Chen Xianhao Yu Junje Zhang Zhen Zou Zhiqiang Lu | 2023 | Insect Science2023，30，3： | 1 |

| 10 | Bioprinted constructs that simulate nerve-bone crosstalk to improve microenvironment for bone repair显示文摘Crosstalk between nerves and bone is essential for bone repair,for which Schwann cells(SCs)are crucial in the regulation of the microenvironment.Considering that exosomes are critical paracrine mediators for intercellular communication that exert important effects in tissue repair,the aim of this study is to confirm the function and molecular mechanisms of Schwann cell-derived exosomes(SC-exos)on bone regeneration and to propose engineered constructs that simulate SC-mediated nerve-bone crosstalk.SCs promoted the proliferation and differentiation of bone marrow mesenchymal stem cells(BMSCs)through exosomes.Subsequent molecular mechanism studies demonstrated that SC-exos promoted BMSC osteogenesis by regulating the TGF-βsignaling pathway via let-7c-5p.Interestingly,SC-exos promoted the migration and tube formation performance of endothelial progenitor cells.Furthermore,the SC-exos@G/S constructs were developed by bioprinting technology that simulated SC-mediated nerve-bone crosstalk and improved the bone regeneration microenvironment by releasing SC-exos,exerting the regulatory effect of SCs in the microenvironment to promote innervation,vascularization,and osteogenesis and thus effectively improving bone repair in a cranial defect model.This study demonstrates the important role and underlying mechanism of SCs in regulating bone regeneration through SC-exos and provides a new engineered strategy for bone repair. | Tianchang Wang Wentao Li Yuxin Zhang Xiang Xu Lei Qiang Weiqiang Miao Xiaokun Yue Xin Jiao Xianhao Zhou Zhenjiang Ma Shuai Li Muliang Ding Junfeng Zhu Chi Yang Hui Wang Tao Li Xin Sun Jinwu Wang | 2023 | Bioactive Materials2023，，9： | 1 |

| 15 | Comparison of diagnosis value for new onset myasthenia gravis by many clinical auxiliary examinations显示文摘BACKGROUND: The clinical values of neostigmine test, clinical electrophysiologic study and acetylcholine receptor antibody detection in diagnosing myasthenia gravis (MG) found newly are unclear in China. OBJECTIVE: To investigate the reference value of common clinical diagnosis parameters in correctly diagnosing untreated MG found newly. DESIGN: Retrospective case analysis. SETTING: Department of Neurology, Beijing Hospital, Ministry of Health. PARTICIPANTS: Totally 156 outpatients with MG admitted to Department of Neurology, Beijing Hospital, Ministry of Health between January 1999 and December 2002. The involved patients, 72 males and 84 females, were aged 2–79 years. They were classified according to Osserman's criteria: ⅡA 72,ⅡB 76, Ⅲ 3 and Ⅳ 5. They were all subjected to being inquired of disease history, neostigmine test, and acetylcholine receptor antibody detection, met the diagnosis criteria of Neuroimmunology Committee of China, and confirmed by clinical electrophysiologic detections; Informed consents were obtained from all the involved subjects. METHODS: ①After admission, every patient was intramuscularly injected with 1.5 mg neostigmine; If the patient was a child, the injection dose was decreased according to his/her age. If his/her score of any observation index after injection was improved ≥ 50% as compared with before injection , his positive index was set as positive. Positive neostigmine test was set if there was one positive index. ②Repetitive nerve stimulation and single fiber electromyography were performed with Dantec Keypoint electromyogram (EMG) apparatus. ③Acetylcholine receptor antibody was detected by ELISA method. MAIN OUTCOME MEASURES: Clinical absolute and relative scores of MG, acetylcholine receptor antibody level, and repetitive nerve stimulation and single fiber electromyography examination results. RESULTS: The positive rates of neostigmine test, repetitive nerve stimulation and single fiber electromyography examination for MG were 86.5%, 82.6%, and 69.2%, respectively, and the positive rate of acetylcholine receptor antibody was 78.8%. CONCLUSION: Standardized neostigmine test has the highest sensitivity to diagnose MG. | Jian Yin Shiguang Wen Yinhong Liu Cuidi Wang Hua Zhang Hong Guo Xianhao Xu | 2007 | Neural Regeneration Research2007，2，7： | 0 |
| 16 | Geometrically Shaped 32QAM and Modified Binary Switching Coding Method in Underwater Visible Light Communication显示文摘Visible light communication(VLC)has emerged as a promising communication method in 6G,particularly in the domain of underwater communication.However,because of its intimate coupling to the lightemitting diodes(LED),the transmission rate is limited by the modulation bandwidth and the nonlinearity of the LED.With current device development,LED bandwidth is substantially lower than that of other optical communication devices,necessitating improved spectral efficiency and nonlinearity robustness to achieve high-speed transmission.In this paper,we propose a hexagonal constellation-based geometrically shaped(GS)32QAM with carrierless amplitude and phase(CAP)modulation for the underwater VLC system.A comprehensive performance comparison of four GS modulation methods,including our proposed hexagonal-32QAM,normal 32QAM,square-32QAM and 32APSK is investigated in both theory and experiment.The hexagonal-32QAM with a modified binary switching coding(BSC)can obtain a Q factor gain of 0.44 dB,and a data rate improvement of 25 Mb/s compared with Gary coding based normal 32QAM.The experimentally results illustrate the feasibility of geometric shaping 32QAM in underwater visible light communication. | SHI Jianyang CAI Jifan QIN Guojin JIN Ruizhe LIN Xianhao CHI Nan | 2022 | Chinese Journal of Electronics2022，31，6： | 0 |
| 17 | REMOBILIZATION AND ACCUMULATION OF IODINE IN MARINE SEDIMENTS, WESTERN ANTARCTIC OCEAN显示文摘Remobilization and accumulation mechanisms of iodine in marine sediments, which are divided into several geochemical environment, are studied. The result shows that iodine is characteristically rich in organic fractions of the sediments on the bottom of bay and pelagic sediments. However, it may be associated with oxyhydroxide and adsorptive phase in a highter percentage at the continental shelf and hemipelagic sediments. The environmental characteristics of remobilization of iodine in surficial sediments are similar to that of iron, that is, it is remobilized on anoxic conditions and converted into solid phases when it is in oxic environments, though the iodine does not act as the electron acceptor. The processes of adsorption and oxidation are responsible for the value of It/Corg in excess of that of planktonic materials other than the organic fraction in surficial sediments. It is a comprehensive effect of organism decomposition, oxyhydroxide reduction, particulate adsorption and pore water | Cheng Xianhao, Xia Weiping, and Zhang HaishengSecond Institute of Oceanography, SOA Hangzhou 310012 | 1992 | Chinese Journal of Polar Science1992，3，1： | 0 |
| 18 | 31.38 Gb/s GaN-based LED array visible light communication system enhanced with V-pit and sidewall quantum well structure显示文摘Although the 5G wireless network has made significant advances,it is not enough to accommodate the rapidly rising requirement for broader bandwidth in post-5G and 6G eras.As a result,emerging technologies in higher frequencies including visible light communication(VLC),are becoming a hot topic.In particular,LED-based VLC is foreseen as a key enabler for achieving data rates at the Tb/s level in indoor scenarios using multi-color LED arrays with wavelength division multiplexing(WDM)technology.This paper proposes an optimized multi-color LED array chip for high-speed VLC systems.Its long-wavelength GaN-based LED units are remarkably enhanced by V-pit structure in their efficiency,especially in the“yellow gap”region,and it achieves significant improvement in data rate compared with earlier research.This work investigates the V-pit structure and tries to provide insight by introducing a new equivalent circuit model,which provides an explanation of the simulation and experiment results.In the final test using a laboratory communication system,the data rates of eight channels from short to long wavelength are 3.91 Gb/s,3.77 Gb/s,3.67 Gb/s,4.40 Gb/s,3.78 Gb/s,3.18 Gb/s,4.31 Gb/s,and 4.35 Gb/s(31.38 Gb/s in total),with advanced digital signal processing(DSP)techniques including digital equalization technique and bit-power loading discrete multitone(DMT)modulation format. | Zengyi Xu Wenqing Niu Yu Liu Xianhao Lin Jifan Cai Jianyang Shi Xiaolan Wang Guangxu Wang Jianli Zhang Fengyi Jiang Zhixue He Shaohua Yu Chao Shen Junwen Zhang Nan Chi | 2023 | Opto-Electronic Science2023，2，5： | 0 |
| 19 | Micro-nanofiber composite biomimetic conduits promote long-gap peripheral nerve regeneration in canine models显示文摘Peripheral nerve injuries may result in severe long-gap interruptions that are challenging to repair.Autografting is the gold standard surgical approach for repairing long-gap nerve injuries but can result in prominent donor-site complications.Instead,imitating the native neural microarchitecture using synthetic conduits is expected to offer an alternative strategy for improving nerve regeneration.Here,we designed nerve conduits composed of high-resolution anisotropic microfiber grid-cordes with randomly organized nanofiber sheaths to interrogate the positive effects of these biomimetic structures on peripheral nerve regeneration.Anisotropic microfiber-grids demonstrated the capacity to directionally guide Schwann cells and neurites.Nanofiber sheaths conveyed adequate elasticity and permeability,whilst exhibiting a barrier function against the infiltration of fibroblasts.We then used the composite nerve conduits bridge 30-mm long sciatic nerve defects in canine models.At 12 months post-implant,the morphometric and histological recovery,gait recovery,electrophysiological function,and degree of muscle atrophy were assessed.The newly regenerated nerve tissue that formed within the composite nerve conduits showed restored neurological functions that were superior compared to sheaths-only scaffolds and Neurolac nerve conduit controls.Our findings demonstrate the feasibility of using synthetic biophysical cues to effectively bridge long-gap peripheral nerve injuries and indicates the promising clinical application prospects of biomimetic composite nerve conduits. | Xianhao Dong Yueyue Yang Zheheng Bao Adam C.Midgley Feiyi Li Shuxin Dai Zhuangzhuang Yang Jin Wang Lihua Liu Wenlei Li Yayuan Zheng Siyang Liu Yang Liu Weijian Yu Jun Liu Meng Fan Meifeng Zhu Zhongyang Shen Gu Xiaosong Deling Kong | 2023 | Bioactive Materials2023，，12： | 0 |
| 20 | A general mechanism of grain growth-Ⅰ.Theory显示文摘The behaviors of grain growth dominate the formation of the microstructure inside polycrystalline materials and thus strongly influence their practical performances.However,grain growth behaviors still remain ambiguous and thus lack a mathematical formula to describe the general evolution despite decades of efforts.Here,we propose a new migration model of grain boundary(GB)and further derive a mathematical expression to depict the general evolution of grain growth in the cellular structures.The expression incorporates the variables influencing growth rate(e.g.GB features,grain size and local grain size distribution)and thus reveals how the normal,abnormal and stagnant behaviors of grain growth occur in polycrystalline systems.In addition,our model correlates quantitatively GB roughening transition with grain growth behavior.The general growth theory may provide new insights into the GB thermodynamics and kinetics during the cellular structure evolution. | Jianfeng Hu Xianhao Wang Junzhan Zhang Jun Luo Zhijun Zhang Zhijian Shen | 2021 | Journal of Materiomics2021，7，5： | 0 |
