| 1 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |
| 2 | Optimal configuration strategy of energy storage system in high photovoltaic penetration micro-grid based on voltage sensitivity analysis显示文摘Energy storage is an effective measure to deal with internal power fluctuation of micro-grid and ensure stable operation, especially in the micro-grid with high photovoltaic(PV) penetration. Its capacity configuration is related to the steady, safety and economy of micro-grid.In order to improve the absorptive capacity of micro-grid on maximizing the use of distributed PV power in micro-grid, and improve the power quality, an optimal energy storage configuration strategy is proposed, which takes many factors into account, such as the topology of micro-grid, the change of irradiance, the load fluctuation and the cable. The strategy can optimize the energy storage allocation model to minimize the storage power capacity and optimize the node configuration.The key electrical nodes are identified by using the sensitivity coefficient of the voltage, and then the model is optimized to simplify calculation. Finally, an example of the European low-voltage micro-grid and a micro-grid system in the laboratory is used to verify the effectiveness of the proposed method.The results show that the proposed method can optimize the allocation of capacity and the node of the energy storage system. | 欧阳静 Pan Guobin Chen Jinxin Chai Fushuai Zhang Libin | 2019 | High Technology Letters2019，25，3： | 1 |
| 3 | An anti-freezing biomineral hydrogel of high strain sensitivity for artificial skin applications显示文摘Mineral hydrogels have caught a lot of attention for their strong competency as artificial skin-like materials.Nonetheless,it remains a great difficulty in fulfilling in one hydrogel system a range of key functionalities that are needed for practical artificial skin applications,i.e.,to be biocompatible,strain-sensitive,ion-conductive,elastic and robust,anti-swelling,and anti-freezing.Here we present a such type of versatile hydrogel that is not only capable to deliver all the above-mentioned key functionalities but also highly stable.This novel hydrogel is constructed by introducing a gelatinous and amorphous multi-ionic biomineral(denoted as Mg-ACCP,containing Mg^(2+),Ca^(2+),CO_(3)^(2−),and PO_(4)^(3−))into the network of biocompatible polyvinyl alcohol(PVA)and sodium alginate(SA).The presence of Mg^(2+)and PO_(4)^(3−)in this hydrogel helps prohibit the crystallization of the biominerals,leading to significantly improved stability.The hydrogel thus obtained delivers excellent mechanical performance due to the chelation between the mineral ions and the organic matrix,and high sensitivity even to subtle pressure and strain applied,such as slight finger bending and gentle tapping.Furthermore,the novel hydrogel features high ionic conductivity,high resistance to swelling,and extraordinary anti-freezing property,holding great promise for applications in different practical scenarios,particularly in aqueous or cold environments. | Junda Shen Peng Du Binbin Zhou Guobin Zhang Xinxue Tang Jie Pan Bo Li Jingyang Zhang Jian Lu Yang Yang Li | 2022 | Nano Research2022，15，7： | 1 |

| 6 | Axial spondyloarthritis:synthetic magnetic resonance imaging in the detection of sacroiliac joint lesions显示文摘To the Editor:Axial spondyloarthritis(axSpA)is characterized by sacroiliac joint inflammation,spine inflammation,bone destruction,and osteogenesis.Ankylosis of the spine and/or hip joints may occur later,significantly affecting the patient’s quality of life.As the earliest and most common imaging finding of axSpA,sacroiliitis can be divided into early active and late structural lesions.Magnetic resonance imaging(MRI)not only detects active inflammatory changes that cannot be found in computed tomography(CT)or X-rays but also has a similar sensitivity to CT in detecting structural lesions. | Ke Zhang Jing Zheng Jielin Pan Yunping Jiang Yingying Zhan Wenjuan Li Hua Zhang Guobin Hong | 2022 | Chinese Medical Journal2022，135，21： | 0 |
| 7 | The First Crested Duck Genome Reveals Clues to Genetic Compensation and Crest Cushion Formation显示文摘The Chinese crested(CC)duck is a unique indigenous waterfowl breed,which has a crest cushion that affects its survival rate.Therefore,the CC duck is an ideal model to investigate the genetic compensation response to maintain genetic stability.In the present study,we first generated a chromosome-level genome of CC ducks.Comparative genomics revealed that genes related to tissue repair,immune function,and tumors were under strong positive selection,indicating that these adaptive changes might enhance cancer resistance and immune response to maintain the genetic stability of CC ducks.We also assembled a Chinese spot-billed(Csp-b)duck genome,and detected the structural variations(SVs)in the genome assemblies of three ducks(i.e.,CC duck,Csp-b duck,and Peking duck).Functional analysis revealed that several SVs were related to the immune system of CC ducks,further strongly suggesting that genetic compensation in the anti-tumor and immune systems supports the survival of CC ducks.Moreover,we confirmed that the CC duck originated from the mallard ducks.Finally,we revealed the physiological and genetic basis of crest traits and identified a causative mutation in TAS2R40 that leads to crest formation.Overall,the findings of this study provide new insights into the role of genetic compensation in adaptive evolution. | Guobin Chang Xiaoya Yuan Qixin Guo Hao Bai Xiaofang Cao Meng Liu Zhixiu Wang Bichun Li Shasha Wang Yong Jiang Zhiquan Wang Yang Zhang Qi Xu Qianqian Song Rui Pan Lingling Qiu Tiantian Gu Xinsheng Wu Yulin Bi Zhengfeng Cao Yu Zhang Yang Chen Hong Li Jianfeng Liu Wangcheng Dai Guohong Chen | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 8 | Illumining phase transformation dynamics of vanadium oxide cathode by multimodal techniques under operando conditions显示文摘Subtle structural changes during electrochemical processes often relate to the degradation of electrode materials.Characterizing the minute-variations in complementary aspects such as crystal structure,chemical bonds,and electron/ion conductivity will give an in-depth understanding on the reaction mechanism of electrode materials,as well as revealing pathways for optimization.Here,vanadium pentoxide (V2O5),a typical cathode material suffering from severe capacity decay during cycling,is characterized by in-situ X-ray diffraction (XRD) and in-situ Raman spectroscopy combined with electrochemical tests.The phase transitions of V2O5 within the 0-1 LiN ratio are characterized in detail.The V--O and V-V distances became more extended and shrank compared to the original ones after charge/discharge process,respectively.Combined with electrochemical tests,these variations are vital to the crystal structure cracking,which is linked with capacity fading.This work demonstrates that chemical bond changes between the transition metal and oxygen upon cycling serve as the origin of the capacity fading. | Guobin Zhang Tengfei Xiong Xuelei Pan Yunlong Zhao Mengyu Yan Haining Zhang Buke Wu Kangning Zhao Liqiang Mai | 2019 | Nano Research2019，12，4： | 0 |
| 9 | Effects of surface nanostructure on boundary lubrication using molecular dynamics显示文摘Molecular dynamics simulations are used to study the boundary lubrication behaviors of squalane lubricant between two iron wall structures during shearing at different pressures and temperatures.Boundary lubrication models with a smooth iron wall and a nanostructured iron wall,respectively,are constructed,and the density distribution of the lubricating film and the velocity distribution in the shearing process are analyzed.The mechanical response of the solid wall is output,and the friction coefficient is calculated.A tribological test is performed with a UMT-2 tribometer under sliding conditions to evaluate the reliability of the simulation method.The results show that the surface nanostructure has a significant effect on the film thickness and delamination of the lubricating film but little effect on the velocity distribution of the lubricating film.The nano strip groove helps to reduce the friction coefficient of the boundary lubrication system. | Ling Pan Hui Yu Shiping Lu Guobin Lin | 2021 | Nanotechnology and Precision Engineering2021，4，3： | 0 |
| 10 | Operando Observation of Structural Evolution and Kinetics of Li[Ni0.6Co0.2Mn0.2]O2 at Elevated Temperature显示文摘Li[Ni0.6Co0.2Mn0.2]O2(NCM622)is one of the best commercialized cathodes in the battery field.However,poor cyclability at relatively high temperature hinders its multiple usages.Here,operando tests were performed to investigate the phase transitions and electron/ion transfer process of lavered NCM622 at 25 and 55℃.The identified spinel structure resulting in the poor cyclability at 55℃ guides the commercialization of batteries at high temperature. | ZHANG Guobin PAN Xuelei YU Kesong YAN Mengyu XIONG Fangyu WU Liming DENG Xuanwci ZHANG Haining MAI Liqiang | 2020 | Chemical Research in Chinese Universities2020，36，4： | 0 |
| 11 | Single-layer angularly-stable bandpass frequency-selective surface with interdigital resonator显示文摘A miniaturized periodic element for constructing bandpass frequency selective surface(FSS)independent of incident angles and polarizations is presented.An interdigital resonator(IR)with one extending finger to connect the two separate parts of the interdigital capacitor is explored to achieve parallel resonance.The equivalent circuit model(ECM)and electric field distributions are introduced to explain frequency performance of FSS.The whole structure has only one layer and possesses a low profile(a thickness of 0.0015λ,where λ represents the resonant wavelength in free space)as well as a small size(0.03λ×0.03λ).This FSS performs as a spatial bandpass filter which exhibits a great angular stability with incident angles ranging from 0° to 80° for both transverse electric(TE)and transverse magnetic(TM)polarizations.As an example,a prototype of one proposed FSS is fabricated and tested.The measured results show a good angular stability. | MA Xin LIU Yunzhe WAN Guobin PAN Aigang | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 0 |
| 12 | Self-erasable dynamic surface patterns via controllable elastic modulus boosting multi-encoded and tamper-proof information storage显示文摘Dynamic surface patterns(DSPs)have attracted significant interest in anti-counterfeiting,enabling information to be stored,encrypted and decrypted in response to external stimuli.However,creating dynamic surface patterns,capable of controlling wrinkling time and independently modulating different information in both wrinkled and fluorescent states,remains a tremendous challenge.These limit DSPs to further enhance tamper-proofing capacity and extend the information storage density.Here,a rationally designed patterning strategy based on controllable elastic modulus was demonstrated to fabricate self-erasable dynamic surface patterns(S-DSPs)that increase information storage density.These novel S-DSPs strategically integrated amino co-oligomers(ACOs)with the 9-anthracenemethanol(9-AM)as skin layers,designing a bilayer multi-encoding system which could carry several different types of information with wrinkled and fluorescent patterns.The ACOs with relatively low molecular weight can endow the elastic modulus of skin layers with a wide range of regulation.As a result,the difference between the compressive strain and the critical wrinkle strain in the bilayer system would be precisely modulated by photo-dimerization to form quick-response(minimum<1 min)and self-erasable(3 min–8 days)wrinkled patterns for S-DSPs.Meanwhile,the fluorescence pattern could be independently erased and reprogrammed without affecting the change in the wrinkle pattern under modulus-controlled conditions.Moreover,controllable self-erasure in S-DSPs significantly develops tamper-proof capabilities in a supply chain.This original strategy could provide a new approach to the tamper-proof,high-density,and multi-encoded information storage in the product security or inkless printing. | Ziquan Fang Xiaofeng Lin Yihui Lin Jiamin Gao Li Gong Ruijun Lin Guoyi Pan Jianyu Wu Wenjing Lin Xudong Chen Guobin Yi | 2023 | Nano Research2023，16，1： | 0 |
