| 2 | Electrochemical properties of carbon-coated LiFePO_4 and LiFe_(0.98)Mn_(0.02)PO_4 cathode materials synthesized by solid-state reaction显示文摘Olivine structured LiFePO 4 /C (lithium iron phosphate) and Mn 2+ -doped LiFe 0.98 Mn 0.02 PO 4 /C powders were synthesized by the solid-state reaction. The effects of manganese partial substitution and different carbon content coating on the surface of LiFePO 4 were considered. The structures and electrochemical properties of the samples were measured by X-ray diffraction (XRD), cyclic voltammetry (CV), charge/discharge tests at different current densities, and electrochemical impedance spectroscopy (EIS). The electrochemical properties of LiFePO 4 cathodes with x wt.% carbon coating (x= 3, 7, 11, 15) at =0.2C, 2C (1C= 170 mAh·g 1 ) between 2.5 and 4.3 V were investigated. The measured results mean that the LiFePO 4 with 7 wt.% carbon coating shows the best rate performance. The discharge capacity of LiFe 0.98 Mn 0.02 PO 4 /C composite is found to be 165 mAh·g 1 at a discharge rate, = 0.2C, and 105 mAh·g 1 at =2C, respectively. After 10 cycles, the discharge capacity has rarely fallen, while that of the pristine LiFePO 4 /C cathode is 150 mAh·g 1 and 98 mAh·g 1 at =0.2 and 2C, respectively. Compared to the discharge capacities of both electrodes above, the evident improvement of the electrochemical performance is observed, which is ascribed to the enhancement of the electronic conductivity and diffusion kinetics by carbon coating and Mn 2+-substitution. | Lin, Ying Zeng, Baozhi Lin, Yingbin Li, Xiaowei Zhao, Guiying Zhou, Ting Lai, Heng Huang, Zhigao | 2012 | Rare Metals2012，31，2： | 3 |
| 3 | Microstructure and magnetic properties of electrodeposited Gd-Co alloy films显示文摘Gd-Co alloy films were synthesized by potentiostatic electrolysis on Cu substrates in urea-acetamide-NaBr-KBr melt at 353 K. The elec- troreduction of Co2+ and Gd3+ was investigated by cyclic voltammetry. The reduction of Co2+ is an irreversible process. Gd3+ cannot be re- duced alone, but it can be inductively co-deposited with Co2+. Both the Gd content and microstructure of the prepared Gd-Co alloy films can be controlled by the deposited potential. The content of Gd was analyzed using an inductively coupled plasma emission spectrometer (ICPES), and the microstructure was observed by scanning electron micrograph (SEM). The films were crystallized by heat-treatment at 823 K for 30 s in Ar atmosphere, and then were investigated by XRD. The hysteresis loops of the Gd-Co alloy films were measured by a vibrat- ing sample magnetometer (VSM). The experimental results reveal that the deposited Gd-Co alloy films are amorphous, while the annealing causes the samples to change from amorphous to polycrystalline, thus enhancing their magnetocrystalline anisotropy and coercivity. More- over, the magnetic properties of the Gd-Co alloy films depend strongly on the Gd content. | LAI Heng LI Jiaxin ZHOU Weichao ZHUANG Bin WU Xiaoping HUANG Zhigao | 2008 | Rare Metals2008，27，6： | 3 |
| 4 | Rice(Oryza sativa L.)seedlings enriched with zinc or manganese:Their impacts on cadmium accumulation and expression of related genes显示文摘Cadmium(Cd)contamination in paddy soils means that the rice produced there may be unsafe for human consumption.A hydroponic study was conducted to enrich rice seedlings with zinc(Zn)or manganese(Mn),and the uptake and transport characteristics of Cd in these Zn-and Mn-rich seedlings were subsequently investigated using a greenhouse pot trial.The results showed that hydroponic cultivation in 10-50μmol L^(-1) Zn(ZnSO_(4)·7 H_(2)O)or50-250μmol L^(-1) Mn(MnSO_(4)·H_(2)O)for 30 d had no significant impact on rice growth,while the accumulation of Zn and Mn was 7.31-18.5 and 25.4-47.7 times higher,respectively,than in the control(no Zn or Mn addition).The accumulation of Cd in the Zn-and Mn-rich rice plants was 26.3%-38.6% and 34.4%-44.5% lower than that in the control,respectively,and the translocation factors of Cd from roots to shoots also decreased by 23.3%-41.3% and 25.3%-37.0%,respectively,after transplanting to Cd-contaminated soils.Furthermore,the relative expression levels of OsIRT1(Oryza sativa iron-regulated transporter 1)were downregulated by 40.1%-59.3% and 16.0%-25.9%,respectively,in the Zn-and Mn-rich seedling roots.This downregulation may indicate a possible mechanism contributing to the reductions in Cd absorption.Field experiments confirmed that the Zn-and Mn-rich seedlings produced brown rice(unpolished rice grains)with significantly decreased concentrations of Cd(34.2%-44.4%).This study provides an innovative method for reducing the food safety risks from rice grown on slightly to moderately Cd-contaminated paddy soils. | Gaoxiang HUANG Changfeng DING Yibing MA Yurong WANG Zhigao ZHOU Shun'an ZHENG Xingxiang WANG | 2021 | Pedosphere2021，31，6： | 2 |
| 5 | Flower-like ZnO modified with BiOI nanoparticles as adsorption/catalytic bifunctional hosts for lithium–sulfur batteries显示文摘Due to the high specific capacity and energy density, lithium–sulfur battery is regarded as a potential energy storage conversion system. However, the serious shuttle effect and the sluggish electrochemical reaction kinetics impede the practical use of lithium–sulfur battery. In the interests of breaking through the above knotty problems, herein we propose to use the polar flower-like Zn O modified by Bi OI nanoparticles as bifunctional host with catalytic and adsorption ability for polysulfides in lithium–sulfur battery.It can be found that this adsorption/catalytic host integrates the functions of adsorption and mutual catalytic conversion of polysulfides, in which the polar flower-like Zn O can effectively capture the polysulfides through strong polar-polar interaction, simultaneously the BiOI nanoparticles can accelerate the mutual conversion of polysulfides to Li2 S through reducing the activation energy and conversion energy barrier required for the electrochemical reaction. As a result, under a sulfur loading of 2.5 mg cm^(-2), the lithium–sulfur battery with Zn O/Bi OI/CNT/S as cathode reveals a considerable initial specific capacity of1267 mAh g^(-1) at a current density of 0.1 C. Even the current density increased to 1 C, the capacity can reach as 873.4 mAh g^(-1), together with a good capacity retention of 67.1% after 400 cycles. Therefore,after systematically study the positive effects of the flower-like ZnO modified by catalytic BiOI nanoparticles on the adsorption and catalytic conversion of polysulfides, this work provides a new idea for the development and application of high-performance lithium–sulfur batteries. | Peng Zeng Hao Yu Manfang Chen Wensheng Xiao Yongfang Li Hong Liu Jing Luo Jiao Peng Dingsheng Shao Ziyi Zhou Zhigao Luo Ying Wang Baobao Chang Xianyou Wang | 2020 | Journal of Energy Chemistry2020，29，12： | 1 |

| 7 | Generation and application of replication-competent Venus-expressing H5N1,H7N9,and H9N2 influenza A viruses显示文摘The generation and application of replication-competent influenza A virus(IAV) expressing a reporter gene represent a valuable tool to elucidate the mechanism of viral pathogenesis and establish new countermeasures to combat the threat of influenza. Here, replication-competent IAVs with a neuraminidase(NA) segment harboring a fluorescent reporter protein, Venus, were generated in the background of H5N1, H7N9, and H9N2 influenza viruses, the three subtypes of viruses with imminent pandemic potential. All three reporter viruses maintained virion morphology, replicated with similar or slightly reduced titers relative to their parental viruses, and stably expressed the fluorescent signal for at least two passages in embryonated chicken eggs. As a proof of concept, we demonstrated that these reporter viruses,used in combination with a high-content imaging system, can serve as a convenient and rapid tool for the screening of antivirals and host factors involved in the virus life cycle. Moreover, the reporter viruses demonstrated similar growth properties and tissue tropism as their parental viruses in mice, among which the H7N9 NA-Venus virus could potentially be used in ex vivo studies to better understand H7N9 pathogenesis or to develop novel therapeutics. | guangwen wang jie zhang fandi kong qibing li jinliang wang shujie ma yuhui zhao libin liang junping li nan sun lizheng guan yuan zhou chenchen zhou shanyu huang zhigao bu li jiang hualan chen chengjun li | 2018 | Science Bulletin2018，63，3： | 1 |
| 8 | Leaf metabolic influence of glyphosate and nanotubes on the Arabidopsis thaliana phyllosphere显示文摘Chemical exposure can indirectly affect leaf microbiota communities,but the mechanism driving this phenomenon remains largely unknown.Results revealed that the co-exposure of glyphosate and multi-carbon nanotubes(CNTs)caused a synergistic inhibitory effect on the growth and metabolism of Arabidopsis thaliana shoots.However,only a slight inhibitory effect was induced by nanotubes or glyphosate alone at the tested concentrations.Several intermediate metabolites of nitrogen metabolism and fatty acid synthesis pathways were upregulated under the combined treatment,which increased the amount of energy required to alleviate the disruption caused by the combined treatment.Additionally,compared with the two individual treatments,the glyphosate/nanotube combination treatment induced greater fluctuations in the phyllosphere bacterial community members with low abundance(relative abundance(RA)<1%)at both the family and genus levels,and among these bacteria some plant growth promotion and nutrient supplement related bacteria were markable increased.Strikingly,strong correlations between phyllosphere bacterial diversity and metabolites suggested a potential role of leaf metabolism,particularly nitrogen and carbohydrate metabolism,in restricting the range of leaf microbial taxa.These correlations between phyllosphere bacterial diversity and leaf metabolism will improve our understanding of plant-microbe interactions and the extent of their drivers of variation and the underlying causes of variability in bacterial community composition. | Mingjing Ke Yizhi Ye Yan Li Zhigao Zhou Nuohan Xu Lan Feng Jinfeng Zhang Tao Lu Zhiqiang Cai Haifeng Qian | 2021 | Journal of Environmental Sciences2021，33，8： | 1 |
| 9 | The First Reported Case of COVID-19 and Plasmodium ovale Malaria Coinfection—Guangdong Province,China,January 2021显示文摘The current coronavirus disease 2019(COVID-19)pandemic has posed an unprecedented challenge to global health(1–3).The clinical symptoms of COVID-19 are similar to those of malaria,such as fever,myalgia,fatigue,headache,and gastrointestinal symptoms.Due to the heavy burden of medical services and the possible shortage of resources caused by the long-term COVID-19 pandemic,the risk of coinfection of malaria and COVID-19 is a matter of particular concern.Here we reported the first case of COVID-19 coinfection with Plasmodium ovale(P.ovale)malaria in a 47-year-old man who had been previously diagnosed with Plasmodium infection and incompletely treated with antimalarial drugs. | Muxin Chen Shitong Gao Lin Ai Jiaxu Chen Tiejian Feng Zhigao Chen Xiaomin Zhang Shaoyu Deng Zidan Lin Yijun Tang Qian Zhang Gengcheng He Huawei Xiong Xiao-nong Zhou Renli Zhang Dana Huang | 2021 | China CDC weekly2021，3，21： | 0 |
| 10 | Metabolomic modulations in a freshwater microbial community exposed to the fungicide azoxystrobin显示文摘An effective broad-spectrum fungicide,azoxystrobin(AZ),has been widely detected in aquatic ecosystems,potentially affecting the growth of aquatic microorganisms.In the present study,the eukaryotic alga Monoraphidium sp.and the cyanobacterium Pseudanabaena sp.were exposed to AZ for 7 days.Our results showed that 0.2–0.5 mg/L concentrations of AZ slightly inhibited the growth of Monoraphidium sp.but stimulated Pseudanabaena sp.growth.Meanwhile,AZ treatment effectively increased the secretion of total organic carbon(TOC)in the culture media of the two species,and this phenomenon was also found in a freshwater microcosm experiment(containing the natural microbial community).We attempted to assess the effect of AZ on the function of aquatic microbial communities through metabolomic analysis and further explore the potential risks of this compound.The metabonomic profiles of the microcosm indicated that the most varied metabolites after AZ treatment were related to the citrate cycle(TCA),fatty acid biosynthesis and purine metabolism.We thereby inferred that the microbial community increased extracellular secretions by adjusting metabolic pathways,which might be a stress response to reduce AZ toxicity.Our results provide an important theoretical basis for further study of fungicide stress responses in aquatic microcosm microbial communities,as well as a good start for further explorations of AZ detoxification mechanisms,which will be valuable for the evaluation of AZ environmental risk. | Mengwei Zhang Wanyue Liu Qian Qu Mingjing Ke Zhenyan Zhang Zhigao Zhou Tao Lu Haifeng Qian | 2020 | Journal of Environmental Sciences2020，32，11： | 0 |

| 12 | Reversible data hiding using a transformer predictor and an adaptive embedding strategy显示文摘In the field of reversible data hiding(RDH),designing a high-precision predictor to reduce the embedding distortion and developing an effective embedding strategy to minimize the distortion caused by embedding information are the two most critical aspects.In this paper,we propose a new RDH method,including a predictor based on a transformer and a novel embedding strategy with multiple embedding rules.In the predictor part,we first design a transformer-based predictor.Then,we propose an image division method to divide the image into four parts,which can use more pixels as context.Compared with other predictors,the transformer-based predictor can extend the range of pixels for prediction from neighboring pixels to global ones,making it more accurate in reducing the embedding distortion.In the embedding strategy part,we first propose a complexity measurement with pixels in the target blocks.Then,we develop an improved prediction error ordering rule.Finally,we provide an embedding strategy including multiple embedding rules for the first time.The proposed RDH method can effectively reduce the distortion and provide satisfactory results in improving the visual quality of data-hidden images,and experimental results show that the performance of our RDH method is leading the field. | Linna ZHOU Zhigao LU Weike YOU Xiaofei FANG | 2023 | Frontiers of Information Technology & Electronic Engineering2023，24，8： | 0 |
| 13 | Single cell RNA and immune repertoire prowling of COVID-19 patients reveal novel neutralizing antibody显示文摘There is no doubt that COVID-19 outbreak is currently the biggest public health threat,which has caused catastrophic con sequences in many countries and regions.As host immunity is key to fighting against virus infection,it is important to characterize the immunologic changes in the COVID-19 patients,and to explore potential therapeutic candidates.The most efficient ways to end this pandemic are to vaccinate the susceptible population,and to use specific drugs,such as monoclonal antibodies against the viral spike protein(S protein),to treat the affected individuals.Several promising neutralizing antibodies have recently been reported(Cao et al.,2020;Lv et al.,2020). | Fang Li Meng Luo Wenyang Zhou Jinliang Li Xiyun Jin Zhaochun Xu Liran Juan Zheng Zhang Yuou Li Renqiang Liu Yiqun Li Chang Xu Kexin Ma Huimin Cao Jingwei Wang Pingping Wang Zhigao Bu Qinghua Jiang | 2021 | Protein & Cell2021，12，10： | 0 |
