| 2 | Effect of Ginkgo biloba leaf extract on cerebral cortex amino acid levels in cerebral ischemia model rats显示文摘OBJECTIVE: To investigate the effect of Ginkgo biloba leaf extract on amino acid levels in the cerebral cortex of cerebral ischemia model rats induced by middle cerebral artery occlusion(MCAO).METHODS: A rat model of cerebral ischemia was established by MCAO. Male rats were divided into a negative control group(Control), a sham-operated group(Sham), an ischemic group(MCAO), and an ischemic group treated with Ginkgo biloba leaf extract(MCAO_D). All groups were divided into two subgroups with occlusion times of 12 and 24 h, respectively. The levels of 18 endogenous amino acids in the cerebral cortex were quantified by triple quadrupole-liquid chromatography-mass spectrometry.RESULTS: Compared with the MCAO group, behavioral performance, neurological deficit score, and cerebral infarct volume were significantly improved in the MCAO_D group(P < 0.05, P < 0.01). Compared with the sham group, the levels of 17 amino acids in the cerebral cortex were markedly changed in the MCAO group. The levels of Alanine(Ala), Isoleucine(Ile), Glutamic acid(Glu), Serine(Ser), Valine(Val), Phenylalanine(Phe), Proline(Pro),Threonine(Thr), Lysine(Lys), Tyrosine(Tyr), Hydroxyproline(Hyp), Arginine(Arg), Leucine(Leu),Tryptophan(Trp), and Glycine(Gly) were increased(P < 0.001, P < 0.05), while levels of Gln and Tau were decreased(P < 0.001, P < 0.05). Compared with the MCAO group, Ginkgo biloba extract treatment in the MCAO_D group significantly down-regulated the levels of 11 amino acids, especially those of Arg, Thr, and Ser in 12 or 24 h.CONCLUSION: Injection of Ginkgo biloba leaf extract has a therapeutic effect on model rats with MCAO-induced cerebral ischemia by acting on amino acids in the cerebral cortex. This effect might be associated with the regulation of amino acid metabolism in the cerebral cortex. | Cui Yiran Wu Hongwei Liu Mengting Qin Haijiao Liu Xin Yang Hongjun | 2018 | Journal of Traditional Chinese Medicine2018,38,5: | 8 |
| 3 | Ultra-sensitive Nanoprobe Modified with Tumor Cell Membrane for UCL/MRI/PET Multimodality Precise Imaging of Triple-Negative Breast Cancer显示文摘Triple-negative breast cancer(TNBC)is a subtype of breast cancer in which the estrogen receptor and progesterone receptor are not expressed,and human epidermal growth factor receptor 2 is not amplified or overexpressed either,which make the clinical diagnosis and treatment very challenging.Molecular imaging can provide an effective way to diagnose TNBC.Upconversion nanoparticles(UCNPs),are a promising new generation of molecular imaging probes.However,UCNPs still need to be improved for tumor-targeting ability and biocompatibility.This study describes a novel probe based on cancer cell membrane-coated upconversion nanoparticles(CCm-UCNPs),owing to the low immunogenicity and homologous-targeting ability of cancer cell membranes,and modified multifunctional UCNPs.This probe exhibits excellent performance in breast cancer molecular classification and TNBC diagnosis through UCL/MRI/PET tri-modality imaging in vivo.By using this probe,MDA-MB-231 was successfully differentiated between MCF-7 tumor models in vivo.Based on the tumor imaging and molecular classification results,the probe is also expected to be modified for drug delivery in the future,contributing to the treatment of TNBC.The combination of nanoparticles with biomimetic cell membranes has the potential for multiple clinical applications. | Hanyi Fang Mengting Li Qingyao Liu Yongkang Gai Lujie Yuan Sheng Wang Xiao Zhang Min Ye Yongxue Zhang Mingyuan Gao Yi Hou Xiaoli Lan | 2020 | Nano-Micro Letters2020,12,5: | 5 |
| 4 | Evaluation of the four potential Cretaceous-Paleogene (K-Pg) boundaries in the Nanxiong Basin based on evidences from volcanic activity and paleoclimatic evolution显示文摘Determining the location of the Cretaceous-Paleogene(K-Pg) boundary in terrestrial strata is highly significant for studying the evolution of terrestrial ecosystems at the end of the Cretaceous(especially the extinction of non-avian dinosaurs). At present, research on terrestrial K-Pg boundaries worldwide is concentrated in the middle and high latitudes, such as North America and Northeast China. Although many studies have also been carried out in the Nanxiong Basin, located at low latitudes(which has become the standard for dividing and comparing the continental K-Pg stratigraphy in China), many researchers have proposed four possible boundaries from different perspectives. Therefore, the exact location remains to be determined. In this study, the total mercury(Hg) content, environmental magnetism, geochemistry, and other parameters for the samples collected near the four boundaries were determined and compared with existing records. Results indicated that: 1) The total Hg content significantly increased in the upper part of the Zhenshui Formation and Pingling part of the Shanghu Formation with sharp fluctuations. As per latest dating results of Deccan Traps, the significantly high Hg value was attributed to the Deccan Traps eruption. Boundary 1 was located in the middle of the Hg anomaly interval, which was consistent with the relationship between the global K-Pg boundary and time of volcanic eruption. 2) The reconstructed paleoclimate evolution curve revealed that the red sediments in the basin recorded the late Maastrichtian warming event(66.2 Ma). Regarding the relationship between the four boundaries and this warming event, only boundary 1 was found to be closest to the real K-Pg boundary of the Nanxiong Basin. | Mengting ZHAO Mingming MA Mei HE Yudan QIU Xiuming LIU | 2021 | Science China Earth Sciences2021,64,4: | 4 |
| 5 | Recent Advancements on Photothermal Conversion and Antibacterial Applications over MXenes-Based Materials显示文摘The pernicious bacterial proliferation and emergence of super-resistant bacteria have already posed a great threat to public health,which drives researchers to develop antibiotic-free strategies to eradicate these fierce microbes.Although enormous achievements have already been achieved,it remains an arduous challenge to realize efficient sterilization to cut off the drug resistance generation.Recently,photothermal therapy(PTT)has emerged as a promising solution to efficiently damage the integrity of pathogenic bacteria based on hyperthermia beyond their tolerance.Until now,numerous photothermal agents have been studied for antimicrobial PTT.Among them,MXenes(a type of two-dimensional transition metal carbides or nitrides)are extensively investigated as one of the most promising candidates due to their high aspect ratio,atomic-thin thickness,excellent photothermal performance,low cytotoxicity,and ultrahigh dispersibility in aqueous systems.Besides,the enormous application scenarios using their antibacterial properties can be tailored via elaborated designs of MXenes-based materials.In this review,the synthetic approaches and textural properties of MXenes have been systematically presented first,and then the photothermal properties and sterilization mechanisms using MXenes-based materials are documented.Subsequently,recent progress in diverse fields making use of the photothermal and antibacterial performances of MXenes-based materials are well summarized to reveal the potential applications of these materials for various purposes,including in vitro and in vivo sterilization,solar water evaporation and purification,and flexible antibacterial fabrics.Last but not least,the current challenges and future perspectives are discussed to provide theoretical guidance for the fabrication of efficient antimicrobial systems using MXenes. | Shuyan Hao Hecheng Han Zhengyi Yang Mengting Chen Yanyan Jiang Guixia Lu Lun Dong Hongling Wen Hui Li Jiurong Liu Lili Wu Zhou Wang Fenglong Wang | 2022 | Nano-Micro Letters2022,14,11: | 4 |
| 6 | Cold Stress-induced Glucosyltransferase CsUGT78A15 is Involved in the Formation of Eugenol Glucoside in Camellia sinensis显示文摘Eugenol is a natural phenolic compound known for its health-promoting properties and its ability to add a floral scent to tea plants.Plant eugenol glycosides have been identified and shown to make important contributions to fruit floral quality.However,the details of their biosynthesis and metabolism in tea plants are still unknown.Here,eugenol glucoside was unambiguously identified as a native metabolite in the tea plant,and its biosynthesis was shown to be induced by low temperature treatment.Through the analysis of UGTs induced by low temperature,the glycosyltransferase CsUGT78A15 was identified in tea,and its encoded protein was shown to catalyze the glucosylation of eugenol.Vmax/Km ratios showed that eugenol was the most suitable substrate for CsUGT78A15.Sugar donor preference analysis showed that CsUGT78A15 had a higher selectivity for glucose,followed by galactose and glucuronic acid.The expression of CsUGT78A15was correlatedwith the accumulation of eugenol glucoside in different tissues and genotypes of tea.Down-regulation of CsUGT78A15 led to a decreased eugenol glucoside content under cold stress,indicating that CsUGT78A15 plays an important role in the biosynthesis of eugenol glucoside under cold stress.The identification of eugenol glucoside in the tea plant and the discovery of a cold stress-induced eugenol glucosyltransferase in tea provide the foundation for the improvement of tea flavor under cold stress and the biotechnological production of eugenol glucoside. | Mingyue Zhao Binbin Cai Jieyang Jin Na Zhang Tingting Jing Jingming Wang Yuting Pan Zixiang Zhou Yifan Zhao Yingying Feng Feng Yu Mengting Zhang Yating Li Zhonghua Liu Chuankui Song | 2020 | Horticultural Plant Journal2020,6,6: | 4 |
| 7 | A review on cyber security named entity recognition显示文摘With the rapid development of Internet technology and the advent of the era of big data,more and more cyber security texts are provided on the Internet.These texts include not only security concepts,incidents,tools,guidelines,and policies,but also risk management approaches,best practices,assurances,technologies,and more.Through the integration of large-scale,heterogeneous,unstructured cyber security information,the identification and classification of cyber security entities can help handle cyber security issues.Due to the complexity and diversity of texts in the cyber security domain,it is difficult to identify security entities in the cyber security domain using the traditional named entity recognition(NER)methods.This paper describes various approaches and techniques for NER in this domain,including the rule-based approach,dictionary-based approach,and machine learning based approach,and discusses the problems faced by NER research in this domain,such as conjunction and disjunction,non-standardized naming convention,abbreviation,and massive nesting.Three future directions of NER in cyber security are proposed:(1)application of unsupervised or semi-supervised technology;(2)development of a more comprehensive cyber security ontology;(3)development of a more comprehensive deep learning model. | Chen GAO Xuan ZHANG Mengting HAN Hui LIU | 2021 | Frontiers of Information Technology & Electronic Engineering2021,22,9: | 3 |
| 8 | Zephyranthes-like Co2NiSe4 arrays grown on 3D porous carbon frame-work as electrodes for advanced supercapacitors and sodium-ion batteries显示文摘Developing suitable electrode materials for electrochemical energy storage devices by biomorph assisted design has become a fascinating topic due to the fantastic properties derived from bio-architectures.Herein,zephyranthes-like Co_(2)NiSe_(4)arrays grown on butterfly wings derived three-dimensional(3D)carbon framework(Z-Co_(2)NiSe_(4)/BWC)is fabricated via hydrothermal assembly and further conversion method.Benefiting from its unique structure and multi-components,the obtained Z-Co_(2)NiSe_(4)/BWC electrode for supercapacitor delivers an excellent specific capacitance of 2,280 F·g^(-1)at 1 A·g^(-1).Impressively,the constructed asymmetric supercapacitor using Co_(2)NiSe_(4)/BWC as positive electrode and activated butterfly wings carbon as negative electrode acquires a high energy density of 42.9 Wh·kg^(-1)at a power density of 800 W·kg^(-1)with robust stability of 94.6%capacitance retention at 10 A·g^(-1)after 5,000 cycles.Moreover,the Z-Co_(2)NiSe_(4)/BWC as anode for sodium-ion batteries exhibits a high specific capacity of 568 mAh·g^(-1)at 0.1 A·g^(-1)and high cycling stability(maintaining 80.1%of the second cycle after 100 cycles).The outstanding electrochemical performances are ascribed to that the synergistic effect of bimetallic selenides and N-doped carbon improves electrochemical activities and conductivity.One-dimensional(1D)nanoneedles grown on 3D porous framework increase the exposure of redox-active sites,endow adequate transmission channels of electrons/ions,and guarantee stability of the electrode during charge/discharge processes.This study will shed light on the avenue towards extending such nanohybrids to excellent energy storage applications. | Yanchun Xue Xingmei Guo Mengrong Wu Jiale Chen Mengting Duan Jing Shi Junhao Zhang Fu Cao Yuanjun Liu Qinghong Kong | 2021 | Nano Research2021,14,10: | 3 |
| 9 | Synthesis, characterization and tribological evaluation of novel1,4-diazabicyclo[2.2.2]octane based dicationic ionic liquids as efficient antiwear lubricant additives显示文摘Ionic liquids have developed and been applied in lubricant field since 2001. Nevertheless, it is little known about novel dicationic ionic liquids for tribology applications in the past several years. In this paper, a sequence of novel dicationic ionic liquids based on 1,4-diazabicyclo[2.2.2]octane cations(DABCO) and different anions have been designed and identified. The structures of ILs were confirmed by Fourier transform infrared(FTIR) spectra, multinuclear(~1H,^(13)C,^(11)B,^(31)P and ^(19)F) magnetic resonance and mass spectrometry. The effects of anion type on thermal properties, wettability, kinematic viscosity and tribological properties were studied. It is found that all of these dicationic ionic liquids as additives exhibit excellent anti-wear and friction-reducing properties in PEG synthetic base oil under boundary lubrication conditions for steel-to-steel contact, which offers great potential for the highly efficient lubricant additives. Simultaneously, novel 1,4-diazabicyclo[2.2.2]octane cation offers an exceptional chance for the research and development of dicationic ionic liquids in various applications. | ZHAO LiNa CAI Tao ZHANG YunXiao YE MengTing SHANG WangJi LIU Dan TONG DingYi LIU ShengGao | 2019 | Science China(Technological Sciences)2019,62,2: | 3 |
| 10 | Functional additives for solid polymer electrolytes in flexible and high-energy-density solid-state lithium-ion batteries显示文摘Solid polymer electrolytes(SPEs)have become increasingly attractive in solid-state lithium-ion batteries(SSLIBs)in recent years because of their inherent properties of flexibility,processability,and interfacial compatibility.However,the commercialization of SPEs remains challenging for flexible and high-energy-density LIBs.The incorporation of functional additives into SPEs could significantly improve the electrochemical and mechanical properties of SPEs and has created some historical milestones in boosting the development of SPEs.In this study,we review the roles of additives in SPEs,highlighting the working mechanisms and functionalities of the additives.The additives could afford significant advantages in boosting ionic conductivity,increasing ion transference number,improving high-voltage stability,enhancing mechanical strength,inhibiting lithium dendrite,and reducing flammability.Moreover,the application of functional additives in high-voltage cathodes,lithium-sulfur batteries,and flexible lithiumion batteries is summarized.Finally,future research perspectives are proposed to overcome the unresolved technical hurdles and critical issues in additives of SPEs,such as facile fabrication process,interfacial compatibility,investigation of the working mechanism,and special functionalities. | Hao Chen Mengting Zheng Shangshu Qian Han Yeu Ling Zhenzhen Wu Xianhu Liu Cheng Yan Shanqing Zhang | 2021 | Carbon Energy2021,3,6: | 3 |
| 11 | Exact Solutions of VNE: A Survey显示文摘Network virtualization is an enabling technology of running multiple virtual networks on a shared substrate network. It aims to deal with the ossification of current network architecture. As a crucial component of network virtualization, virtual network embedding(VNE) can efficiently and effectively allocates the substrate resource to proposed virtual network requests. According to the optimization strategy, VNE approaches can be classified into three categories: exact, heuristic and meta-heuristic solution. The VNE exact solution is the foundation of its corresponding heuristic and meta-heuristic solutions. This paper presents a survey of existing typical VNE exact solutions, and open problems for the future research of VNE exact solutions are proposed. | Haotong Cao Longxiang Yang Zeyuan Liu Mengting Wu | 2016 | China Communications2016,13,6: | 3 |
| 12 | Elucidation of the sodium kinetics in layered P-type oxide cathodes显示文摘Sodium-ion intercalation oxides generally possess high compositional diversity according to their different stacking sequences.The sodium diffusion pathway in layered P-type materials used in sodium-ion batteries is open,which can increase their rate capability by directly transmitting Na+between adjacent triangular prismatic channels,rather than passing through an intermediate tetrahedral site in O-type structure.However,how the structure chemistry of the P-type oxides determines their electrochemical properties has not been fully understood yet.Herein,by comparing the crystalline structures,electrochemical behaviors,ion/electron transport dynamics of a couple of P-type intercalation cathodes,P2-Na_(2/3)Ni1/3Mn_(2/3)O_(2)and P3-Na_(2/3)Ni_(1/3)Mn_(2/3)O_(2)with the same compositions,we demonstrate experimentally and computationally that the P2 phase delivers better cycling stability and rate capability than the P3 counterpart due to the predominant contribution of the faster intrinsic Na diffusion kinetics in the P2 bulk.We also point out that it is the electronic conductivity that captures the key electrochemistry of layered P3-type materials and makes them possible to enhance the sodium storage performance.The results reveal that the correlation between stacking structure and functional properties in two typical layered P-type cathodes,providing new guidelines for preparing and designing alkali-metal layered oxide materials with improved battery performance. | Lianzheng Yu Haojie Dong Yu-Xin Chang Zhiwei Cheng Kang Xu Yi-Hu Feng Duo Si Xu Zhu Mengting Liu Bing Xiao Peng-Fei Wang Sailong Xu | 2022 | Science China Chemistry2022,65,10: | 3 |

| 14 | Optimization of Fermentation Conditions for Xylanase Production by Aspergillus niger NS-1显示文摘In this study,a xylanase-producing Aspergillus niger strain,NS-1,was screened and isolated from agricultural and forestry wastes. Based on single-factor experiments,the effects of different carbon sources,composite carbon sources,nitrogen sources,calcium carbonate concentrations,initial p H and surfactants on xylanase production by A. niger NS-1 were investigated. The results indicated that the most appropriate carbon source was corncobs; the best composite carbon source was corncobs + xylan,which was conducive to xylanase secretion; the most suitable nitrogen source was ammonium sulfate. Xylanase activity reached the highest in the medium added with 1. 5% calcium carbonate and SDS as a surfactant with an initial p H of 5. 0. This study provided the basis for the production of high-activity xylanase. | Mengting LIU Juanjuan DU Yan ZHOU Jiawei HUANG Xin WANG | 2016 | Agricultural Biotechnology2016,5,1: | 3 |
| 15 | Full-spectrum cell-free RAN for 6G systems:system design and experimental results显示文摘With distributed transceivers and scalable cooperative transmission,cell-free massive multipleinput multiple-output(CF-mMIMO)technology eliminates the“cells”of traditional mobile communications,thereby significantly improving the performance of wireless networks.CF-mMIMO is considered as a major technical tool for achieving the key performance indicators of sixth generation(6G)mobile communication systems.In this paper,a scalable implementation architecture for CF-mMIMO is proposed,based on which potential key technologies such as channel information acquisition,transceiver design,dynamic user and access point association,and novel duplexing are introduced.Finally,based on low-cost commercial access points,a CF-mMIMO testbed with 64 transmit and receive antennas is developed,and the performance of the distributed receiver design is evaluated. | Dongming WANG Xiaohu YOU Yongming HUANG Wei XU Jiamin LI Pengcheng ZHU Yanxiang JIANG Yang CAO Xinjiang XIA Ziyang ZHANG Qingji JIANG Pan WANG Dongjie LIU Kang ZHENG Mengting LOU Jing JIN Qixing WANG Jiangzhou WANG | 2023 | Science China(Information Sciences)2023,66,3: | 3 |
| 16 | Updated annotation of the wild strawberry Fragaria vesca V4 genome显示文摘The diploid strawberry Fragaria vesca serves as an ideal model plant for cultivated strawberry(Fragaria×ananassa,8x)and the Rosaceae family.The F.vesca genome was initially published in 2011 using older technologies.Recently,a new and greatly improved F.vesca genome,designated V4,was published.However,the number of annotated genes is remarkably reduced in V4(28,588 genes)compared to the prior annotations(32,831 to 33,673 genes).Additionally,the annotation of V4(v4.0.a1)implements a new nomenclature for gene IDs(FvH4_XgXXXXX),rather than the previous nomenclature(geneXXXXX).Hence,further improvement of the V4 genome annotation and assigning gene expression levels under the new gene IDs with existing transcriptome data are necessary to facilitate the utility of this high-quality F.vesca genome V4.Here,we built a new and improved annotation,v4.0.a2,for F.vesca genome V4.The new annotation has a total of 34,007 gene models with 98.1%complete Benchmarking Universal Single-Copy Orthologs(BUSCOs).In this v4.0.a2 annotation,gene models of 8,342 existing genes are modified,9,029 new genes are added,and 10,176 genes possess alternatively spliced isoforms with an average of 1.90 transcripts per locus.Transcription factors/regulators and protein kinases are globally identified.Interestingly,the transcription factor family FAr-red-impaired Response 1(FAR1)contains 82 genes in v4.0.a2 but only two members in v4.0.a1.Additionally,the expression levels of all genes in the new annotation across a total of 46 different tissues and stages are provided.Finally,miRNAs and their targets are reanalyzed and presented.Altogether,this work provides an updated genome annotation of the F.vesca V4 genome as well as a comprehensive gene expression atlas with the new gene ID nomenclature,which will greatly facilitate gene functional studies in strawberry and other evolutionarily related plant species. | Yongping Li Mengting Pi Qi Gao Zhongchi Liu Chunying Kang | 2019 | Horticulture Research2019,6,1: | 2 |
| 17 | Designing specific bacterial 16S primers to sequence and quantitate plant endo-bacteriome显示文摘Plant endophytic bacteria colonize the internal tissues of plants and interact with plants closely.The past two decades have witnessed the increasing application of next-generation 16S r RNA gene sequencing in the investigation of bacterial communities.However,deciphering plant endo-bacterial communities by this method is difficult because of the co-amplification of massive plant organellar DNAs with bacterial 16S.Here,we designed polymerase chain reaction(PCR) primer sets,including799F/1107R,322F/796R,and 322F-Dr/796Rs(primer pair 322F/796R with a penultimate-base substitution in 322F),that can specifically amplify bacterial 16S from plant total DNAs.We computationally and experimentally evaluated the specificity,coverage,and accuracy of the newly designed primer sets.Both 799F/1107R and 322F-Dr/796Rs produced plant DNA-free 16S amplicon libraries or reduced plant DNA contamination to lower than 5% for the plant materials with extremely-low-abundance bacterial communities.The primer set 322F-A/796R was used through absolute quantitative PCR to quantitate the population size of rice leaf or root endo-bacteriome,which revealed 10^(6)–10^(7) and 10^(9)–10^(10) bacteria per gram fresh weight,respectively.These 16S primer sets and amplification methods enable the simple and inexpensive next-generation sequencing and quantification of plant endo-bacteriome,which will significantly advance studies on the plant-related microbiome. | Liying Chen Mengting Zhang Da Liu Hongbo Sun Jianxiang Wu Yan Huo Xiaoying Chen Rongxiang Fang Lili Zhang | 2022 | Science China(Life Sciences)2022,65,5: | 2 |
| 18 | Learning to focus: cascaded feature matching network for few-shot image recognition显示文摘Generally, deep networks learn to recognize a category of objects by training on a large number of annotated images accurately. However, a meta-learning problem known as a low-shot image recognition task occurs when a few images with annotations are available for learning a recognition model for a single category. Consequently, the objects in testing/query and training/support image datasets are likely to vary in terms of size, location, style, and so on. In this paper, we propose a method, cascaded feature matching network(CFMN), to solve this problem. We train the meta-learner to learn a more fine-grained and adaptive deep distance metric using feature matching block, which aligns associated features together and naturally ignores non-discriminative features. By applying the proposed feature matching block in different layers of the network, multi-scale information among the compared images is incorporated into the final cascaded matching feature, which boosts the recognition performance and generalizes better by learning on relationships. Moreover, the experiments for few-shot learning(FSL) using two standard datasets:miniImageNet and Omniglot, confirm the effectiveness of our proposed method. Besides, the multi-label fewshot task is first studied on a new data split of the COCO dataset, which further shows the superiority of the proposed feature matching network when performing the FSL in complex images. | Mengting CHEN Xinggang WANG Heng LUO Yifeng GENG Wenyu LIU | 2021 | Science China(Information Sciences)2021,64,9: | 2 |
| 19 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023,66,5: | 2 |
| 20 | A channel-confined strategy for synthesizing CoN-CoO_(x)/C as efficient oxygen reduction electrocatalyst for advanced zinc-air batteries显示文摘Designing hybrid transition metal compounds with optimized electronic structure and firmly dispersing them on a matrix to avoid aggregation and shedding is of great significance for achieving high electrocatalytic performances.Herein,an adsorption-complexation-calcination strategy based on channel confining effect is explored to obtain CoN-CoO_(x)hybrid nanoparticles uniformly dispersed in mesoporous carbon.The CoN-CoO_(x)/C composite exhibits excellent electrocatalytic behavior for oxygen reduction reaction(ORR).The half-wave potential and durability are comparable or superior to those of Pt/C.When applying as cathode catalyst for a primary zinc-air battery,the open-circuit voltage and peak power density reach up to 1.394 V and 109.8 mW·cm^(−2),respectively.A high gravimetric energy density of 950.3 Wh·kgZn^(−1) is delivered at 10 mA·cm^(−2) with good rate capability and stability.Density functional theory(DFT)calculation demonstrates the favorable ORR intermediate adsorbability and metallic characteristics of CoN grains with oxide hybridization to optimize the electronic structure.This work provides a facile adjustable approach for obtaining highly dispersed nanoparticles with controllable hybrid composition on a substrate,which is important for future design and optimization of high-performance electrocatalysts. | Xingmei Guo Wei Zhang Jing Shi Mengting Duan Shanjing Liu Junhao Zhang Yuanjun Liu Shenglin Xiong Qinghong Kong | 2022 | Nano Research2022,15,3: | 1 |
