| 1 | Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children. | Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao | 2020 | World Journal of Pediatrics2020,16,3: | 56 |
| 2 | Dopant-Controlled Synthesis of Water-Soluble Hexagonal NaYF_(4) Nanorods with Efficient Upconversion Fluorescence for Multicolor Bioimaging显示文摘A novel strategy is proposed to directly synthesize water-soluble hexagonal NaYF4 nanorods by doping rare-earth ions with large ionic radius (such as La^(3+), Ce^(3+), Pr^(3+), Nd^(3+), Sm^(3+), Eu^(3+), and Gd^(3+)), and the dopant- controlled growth mechanism is studied. Based on the doping effect, we fabricated water-soluble hexagonal NaYF4:(Yb,Er)/La and NaYF4:(Yb,Er)/Ce nanorods, which exhibited much brighter upconversion fluorescence than the corresponding cubic forms. The sizes of the nanorods can be adjusted over a broad range by changing the dopant concentration and reaction time. Furthermore, we successfully demonstrated a novel depth-sensitive multicolor bioimaging for in vivo use by employing the as-synthesized NaYF4:(Yb,Er)/La nanorods as probes. | Xuefeng Yu Min Li Mengyin Xie Liangdong Chen Yan Li Ququan Wang | 2010 | Nano Research2010,3,1: | 27 |
| 3 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018,61,3: | 12 |

| 6 | OsCIPK7 point-mutation leads to conformation and kinase-activity change for sensing cold response显示文摘Calcineurin B-like interacting protein kinases(CIPKs) play important roles via environmental stress.However, less is known how to sense the stress in molecular structure conformation level. Here, an Os CIPK7 mutant via TILLING procedure with a point mutation in the kinase domain showed increased chilling tolerance, which could be potentially used in the molecular breeding. We found that this point mutation of Os CIPK7 led to a conformationalchange in the activation loop of the kinase domain,subsequently with an increase of protein kinase activity,thus conferred an increased tolerance to chilling stress. | Dajian Zhang Xiaoyu Guo Yunyuan Xu Hao Li Liang Ma Xuefeng Yao Yuxiang Weng Yan Guo Chun-Ming Liu Kang Chong | 2019 | Journal of Integrative Plant Biology2019,61,12: | 8 |

| 8 | FAT1, a direct transcriptional target of E2F1, suppresses cell proliferation, migration and invasion in esophageal squamous cell carcinoma显示文摘Objective: Growing evidence indicates that FAT atypical cadherin 1(FAT1) has aberrant genetic alterations and exhibits potential tumor suppressive function in esophageal squamous cell carcinoma(ESCC). However, the role of FAT1 in ESCC tumorigenesis remains not well elucidated. The aim of this study was to further investigate genetic alterations and biological functions of FAT1, as well as to explore its transcriptional regulation and downstream targets in ESCC.Methods: The mutations of FAT1 in ESCC were achieved by analyzing a combined study from seven published genomic data, while the copy number variants of FAT1 were obtained from an analysis of our previous data as well as of The Cancer Genome Atlas(TCGA) and Cancer Cell Line Encyclopedia(CCLE) databases using the cBioPortal. The transcriptional regulation of FAT1 expression was investigated by chromatin immunoprecipitation(ChIP) and the luciferase reporter assays. In-cell western, Western blot and reverse transcription-quantitative polymerase chain reaction(RT-qPCR) were used to assess the indicated gene expression. In addition, colony formation and Transwell migration/invasion assays were employed to test cell proliferation, migration and invasion.Finally, RNA sequencing was used to study the transcriptomes.Results: FAT1 was frequently mutated in ESCC and was deleted in multiple cancers. Furthermore, the transcription factor E2 F1 occupied the promoter region of FAT1, and depletion of E2 F1 led to a decrease in transcription activity and mRNA levels of FAT1. Moreover, we found that knockdown of FAT1 promoted KYSE30 and KYSE150 cell proliferation, migration and invasion;while overexpression of FAT1 inhibited KYSE30 and KYSE410 cell proliferation, migration and invasion. In addition, knockdown of FAT1 led to enrichment of the mitogen-activated protein kinase(MAPK) signaling pathway and cell adhesion process.Conclusions: Our data provided evidence for the tumor suppressive function of FAT1 in ESCC cells and elucidated the transcriptional regulation of FAT1 by E2 F1, which may facilitate the understanding of molecular mechanisms of the progression of ESCC. | Yu Wang Guangchao Wang Yunping Ma Jinglei Teng Yan Wang Yongping Cui Yan Dong Shujuan Shao Qimin Zhan Xuefeng Liu | 2019 | Chinese Journal of Cancer Research2019,31,4: | 6 |

| 10 | Detection of Citrus yellow vein clearing virus by Quantitative Real-time RT-PCR显示文摘To develop a rapid and reliable detection method for Citrus yellow vein clearing virus(CYVCV), a quantitative real-time reverse transcriptionpolymerase chain reaction(q RT-PCR) system based on SYBR Green I was established by using a pair of specific primers designed from its conserved coat protein gene. The sensitivity, specificity, and applicability of the system were evaluated accordingly. The results showed that amplicons were produced from CYVCV isolates, whereas no amplicons from non-CYVCV citrus virus samples, including Citrus tristeza virus(CTV) and Citrus tatter leaf virus(CTLV), were obtained. The sensitivity of the q RT-PCR was 100-fold higher than that of conventional RT-PCR. An excellent linear correlation(R2= 0.999) was obtained from two standard curves of c RNA, and the amplification efficiency was 102%. The data from field citrus samples detection showed that the q RT-PCR system could be used in determining the concentration of CYVCV in different citrus species. | CHEN Hongming ZHOU Yan WANG Xuefeng ZHOU Changyong YANG Xiuyan LI Zhongan | 2016 | Horticultural Plant Journal2016,2,4: | 4 |
| 11 | Ultrastructure of focal cerebral cortex tissue from rats with focal cortical dysplasia显示文摘BACKGROUND: Developing a model of focal cortical dysplasia in microgyrus and observing the ultrastructure of focal tissue is of important significance for analyzing the pathology of cortical developmental disorder and the factors of structural changes. OBJECTIVE: This study was to observe the pathological characteristics of focal tissue around the microgyrus of rats with cortical developmental disorder using an electron microscope, so as to analyze the causes associated with cerebral cortical developmental disorder. DESIGN: A randomized controlled animal experiment. SETTING: The First Affiliated Hospital of Chongqing Medical University. MATERIALS: This study was carried out in the Chongqing Key Laboratory of Neurology, Room for Electron Microscope of Chongqing Medical University, and Laboratory Animal Center, Research Institute of Surgery, Daping Hospital, Third Military Medical University of Chinese PLA between January 2004 and August 2006. Eighteen healthy newborn male Wistar rats, weighing 3.0-6.0 g, provided by the Laboratory Animal Center, Daping Hospital, Third Military Medical University of Chinese PLA, were involved in this study. The protocol was carried out in accordance with animal ethics guidelines for the use and care of animals. Probes (Chongqing Wire & Cable Factory, China) were made of copper core wire with diameter of 1 mm. METHODS: The rats were randomly divided into 3 groups with 6 in each: normal control group, liquid nitrogen injured group and sham-operation group. ①In the liquid nitrogen injured group, a blunt probe frozen by liquid nitrogen was placed on fronto-parietal crinial bone of rats for 8 s. A 3-5 cm of microgyrus was induced in the unilateral cerebral sensory cortical area. In the sham-operation group, probe was placed at the room temperature. In the normal control group, rats were untouched. ② The conscious state and electrical activity of brain of rats in each group were observed. ③ 2-3 mm thickness of hippocampal tissue with coronary section was taken for observing its ultrastructure under a transmission electron microscope. MAIN OUTCOME MEASURES: ① The ultrastructure of hippocampal tissue. ②The conscious state and electrical activity of brain of rats. RESULTS: Eighteen rats were enrolled in the final analysis. ① Observation of hippocampal ultrastructure: Electromicroscopic pathological findings showed that for each rat of the liquid nitrogen injured group, mitochondrium in the pyramidal neuron around the microgyrus was swelled, endoplasmic reticulum was expanded, glial cells were swelled, water gathered around the blood capillary, partial medullary sheath was degenerated, neuropilem was normal and no obviously abnormal synapse was found. ② Changes in conscious state of rats: Rats in the normal control group and sham-operation group had no convulsive seizure, but those in the liquid nitrogen injured group had occasionally. Most of them showed increased activities, excitation and restlessness, scratching and frequent ' watching face-like activities'. ③Electrical activity of brain of rats: Electroencephalogram recording of liquid nitrogen injured group showed that small wave amplitude of rhythm took the main part. No typical sharp wave, V wave, sharp and slow wave, V and slow waves were discharged. CONCLUSION: Liquid nitrogen can lead to cerebral cortical developmental disorder. Pathological changes of ultrastructure of focal tissue around the microgyrus can provide pathological basis for epilepsy associated with focal cortical developmental disorder. | Xuntai Ma Yong Yan Xuefeng Wang Chunyang Luo Xiaoping Wang Ning Yan Xiangqin Liu Yan Li | 2007 | Neural Regeneration Research2007,2,12: | 3 |
| 12 | Cross-Scale Synthesis of Organic High-k Semiconductors Based on Spiro-Gridized Nanopolymers显示文摘High dielectric constants in organic semiconductors have been identified as a central challenge for the improvement in not only piexoelectric,preolecric,and freeltric efcts but also photoclecric conversion eficiency in OPVs,carrier mobility in OFETS,and charge density in charge-trapping memories.Herein,we report an ultralong persistence length(≈41 nm)efet of spiro-fused organic nanopolymers on dielectric properties,together with excitonic and charge carrier behaviors.The state-of-the-art nanopolymers,namely,nanopolyspirogrids(NPSGs),are synthesized via the simple crossscale Friedel-Crafts polygridlization of AjB-type nanomonomers.The high dielectric constant(k=8.43)of NPSG is firstly achieved by locking spiro-polygridization efect that results in the enhancement of dipole polarization.When doping into a polystyrene-based dielectric layer,such a high-k feature of NPSG increases the feld-ffct carrier mobility from 0.20 to 0.90cm^(2)Vl s'in pentacene OFET devices.Meanwhile,amorphous NPSG film exhibits an ultralow energy disorder(<50 meV)for an exellent zero-field hole mobility of 3.94×10^(-1)cm^(2)V^(-1)s^(-1).surpassing most of the amorphousπconjugated polymers Onganic nanopolymers with high dielectric constants open a new way to break through the bottleneck of eficiency and multifunctionality in the blueprint of the fourth generation semiconductors. | Dongqing Lin Wenhua Zhang Hang Yin Haixia Hu Yang Li He Zhang Le Wang Xinmiao Xie Hongkai Hu Yongxia Yan Haifeng Ling Jin'an Liu Yue Qian Lei Tang Yongxia Wang Chaoyang Dong Linghai Xie Hao Zhang Shasha Wang Ying Wei Xuefeng Guo Dan Lu Wei Huang | 2022 | Research2022,,2: | 3 |
| 13 | Multimodal process monitoring based on transition-constrained Gaussian mixture model显示文摘Reliable process monitoring is important for ensuring process safety and product quality.A production process is generally characterized bymultiple operation modes,and monitoring thesemultimodal processes is challenging.Most multimodal monitoring methods rely on the assumption that the modes are independent of each other,which may not be appropriate for practical application.This study proposes a transition-constrained Gaussian mixture model method for efficient multimodal process monitoring.This technique can reduce falsely and frequently occurring mode transitions by considering the time series information in the mode identification of historical and online data.This process enables the identified modes to reflect the stability of actual working conditions,improve mode identification accuracy,and enhance monitoring reliability in cases of mode overlap.Case studies on a numerical simulation example and simulation of the penicillin fermentation process are provided to verify the effectiveness of the proposed approach inmultimodal process monitoring with mode overlap. | Shutian Chen Qingchao Jiang Xuefeng Yan | 2020 | Chinese Journal of Chemical Engineering2020,28,12: | 3 |
| 14 | Dynamic edge-based biomarker non-invasively predicts hepatocellular carcinoma with hepatitis B virus infection for individual patients based on blood testing显示文摘Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is a major cause of cancer-related deaths in Asia and Africa. Developing effective and non-invasive biomarkers of HCC for individual patients remains an urgent task for early diagnosis and convenient monitoring. Analyzing the transcriptomic profiles of peripheral blood mononuclear cells from both healthy donors and patients with chronic HBV infection in different states (i.e. HBV carrier, chronic hepatitis B, cirrhosis, and HCC), we identified a set of 19 candidate genes according to our algorithm of dynamic network biomarkers. These genes can both characterize different stages during HCC progression and identify cirrhosis as the critical transition stage before carcinogenesis. The interaction effects (i.e. coexpressions) of candidate genes were used to build an accurate prediction model: the so-called edge-based biomarker. Considering the convenience and robustness of biomarkers in clinical applications, we performed functional analysis, validated candidate genes in other independent samples of our collected cohort, and finally selected COL5A1, HLA-DQB1, MMP2, and CDK4 to build edge panel as prediction models. We demonstrated that the edge panel had great performance in both diagnosis and prognosis in terms of precision and specificity for HCC, especially for patients with alpha-fetoprotein-negative HCC. Our study not only provides a novel edge-based biomarker for non-invasive and effective diagnosis of HBV-associated HCC to each individual patient but also introduces a new way to integrate the interaction terms of individual molecules for clinical diagnosis and prognosis from the network and dynamics perspectives. | Yiyu Lu Zhaoyuan Fang Meiyi Li Chen Qian Tao Zeng Lina Lu Qilong Chen Hui Zhang Qianmei Zhou Yan Sun Xuefeng Xue Yiyang Hu Luonan Chen Shibing Su | 2019 | Journal of Molecular Cell Biology2019,11,8: | 3 |
| 15 | Binding Se into nitrogen-doped porous carbon nanosheets for high-performance potassium storage显示文摘Selenium cathode has been demonstrated as a promising candidate of cathode material for low-cost and high-energy density potassium ion batteries(PIBs).Nevertheless,their applica tions are prevented by poor electrochemical perfor-mance due to the shuttle effect of high-order polyselenides,the sluggish diffu-sion of bigger K+,and the huge volumetric expansion during cycling.In this work,we design a multifunctional Se host(N-HCNS)by grafting ZIF-8 derived microporous carbon onto the surface of N-doped porous carbon nanosheets.The obtained N-HCNS carbon matrix integrates conductivity,captivity,and immobility abilities,which inhibits the polyselenides shuttle,improves the Se utilization,and buffers the volume change during cycling.The 3D hollow car-bon skeleton enhances the infiltration of electrolytes.As an cathode for PIBs,the Se@N-HCNS electrode delivers an unprecedented life-span(260 mAh g1 at 1.0 Ag-1 after 2000 cycles)and exhibits a remarkable rate capacity(339 mAh g at 5.0 Ag-l).Density functional theory(DFT)calculation reveals the effective adsorption of K2Se with pyridine and pyrrole nitrogen dop-ing in carbon matrix.The unique synergetic design of electrode not only gives insight into the reaction mechanism but also highly emphasi zes the potential capabilities of N doped carbon in K-Se batteries. | Huijuan Huang Xiao Luo Yu Yao Xuefeng Zhou Yu Jiang ChunliGuo Jiaqin Liu Xiaojun Wu Yan Yu | 2021 | InfoMat2021,3,4: | 3 |

| 17 | 显示恶性孤立肺结节分叶征的理想CT层厚(英文)显示文摘Objective: The aim of this study was to determine an optimal slice thickness that was efficient in revealing lobulation of malignant solitary pulmonary nodules (SPNs) on multi-slice spiral computed tomography (MSCT) images preliminarily. Methods: Fifty patients with malignant SPNs (diameter ≤ 3 cm) underwent multidetector-row computed tomography of the chest in a single-breath-hold technique. The raw data were acquired with a collimation of 0.625 mm. Three sets of contiguous images were reconstructed with 1-, 2-, and 5-mm slice thickness, respectively. The lobulation sign of SPNs on the computed tomography (CT) images presented in 1-, 2-, and 5-mm slice thickness was compared. Using the 1-mm sections as the gold standard, an optimal slice thickness in revealing lobulation sign of SPNs was determined. Results: The 1-mm-thick images CT revealed 98 lobulations (25 with chord distance < 1 mm; 30 with chord distance 1-2 mm; 43 with chord distance > 2 mm) of 45 malignant SPNs. 18 lobulations with chord distance < 1 mm presented in 2-mm-thick sections were as same as those in 1-mm-thick sections. Statistically significant difference in lobulations number was found between that revealed in 2-mm-thick images and that in 1-mm-thick images (P = 0.023 < 0.05). 16 lobulations with chord distance < 1 mm presented in 5-mm-thick sections were as same as that in 1-mm-thick sections. There was statistically significant difference in lobulations number between that revealed in 5-mm-thick images and that in 1-mm-thick images (P = 0.004 < 0.05). The 24 lobulations with chord distance 1-2 mm presented in 2-mm-thick sections were as same as that in 1-mm-thick sections. No statistically significant difference in lobulations number were found between that revealed in 2-mm-thick images and that in 1-mm-thick images (P = 0.261 > 0.05). 13 lobulations with chord distance 1-2 mm presented in 5-mm-thick sections were as same as that in 1-mm-thick sections. There was statistically significant difference in lobulations number between that revealed in 5-mm-thick images and that in 1-mm-thick images (P = 0.003 < 0.05). 40 lobulations with chord distance ﹥2 mm presented in 2-mm-thick sections were as same as that in 1-mm-thick sections. No statistically significant difference in lobulations number was found between that revealed in 2-mm-thick images and that in 1-mm-thick images (P = 0.631 > 0.05). 36 lobulations with chord distance ﹥2 mm presented in 5-mm-thick sections were as same as that in 1-mm-thick sections. There was no statistically significant difference in lobulations number between that revealed in 5-mm-thick images and that in 1-mm-thick images (P = 0.264 > 0.05). Conclusion: It is suggested that the use of 1-mm slice thickness is suitable in revealing lobulations with chord distance < 1 mm. A 2-mm slice thickness is suggested to be used in revealing lobulations with chord distance 1-2 mm and 5-mm slice thickness to be used in revealing lobulations with chord distance > 2 mm. | Shenjiang Li Changcheng Li Xin Wang Debin Liu Wenjie Liang Feng Zhu Yan Zhu Xuefeng Cui Wenjie Bi | 2011 | The Chinese-German Journal of Clinical Oncology2011,10,10: | 2 |

| 19 | Full-faradaic-active nitrogen species doping enables high-energy-density carbon-based supercapacitor显示文摘Nitrogen doping is usually adopted in carbon based supercapacitor to enhance its relatively low energy density by providing extra pseudocapacity.However,the improvement of energy density is normally limited because the content of the introduced nitrogen species is not high and meanwhile only part of them is electrochemically active.Herein,we designed and fabricated a class of hierarchical nitrogen-rich porous carbons(HNPCs)possessing not only very high nitrogen content(up to 21.7 atom%)but also fully electrochemically active nitrogen species(i.e.,pyridinic N,pyrrolic N and oxidized N).Especially,in the synthesis of HNPCs,graphitic carbon nitride(g-C3N4)was used in situ not only as a nitrogen source but also as a catalyst to facilitate the polymerization of phenol and formaldehyde(as carbon precursor)and as a template to create the hierarchical porous structure.As electrodes for aqueous symmetric supercapacitor,the HNPCs with full faradaic-active nitrogen functionalities exhibit excellent supercapacitor performance:high energy density of 36.8 Wh/kg at 2.0 kW/kg(maintaining 25.7 Wh/kg at 38 kW/kg),superior rate capability with 78%capacitance retention from 1.0 to 20 A/g and excellent cycling stability with over95%capacitance retention after 10000 cycles,indicating their promising application potential in electrochemical energy storage.This novel carbon material with high-content and full electrochemically active nitrogen species may find extensive potential applications in the energy storage/conversion,catalysis,adsorption,and so on. | Wei Wei Zhangjing Chen Yan Zhang Jian Chen Liu Wan Cheng Du Mingjiang Xie Xuefeng Guo | 2020 | Journal of Energy Chemistry2020,29,9: | 2 |
