| 1 | Novel Insights into Energy Storage Mechanism of Aqueous Rechargeable Zn/MnO2 Batteries with Participation of Mn2+显示文摘Aqueous rechargeable Zn/MnO2 zinc-ion batteries(ZIBs)are reviving recently due to their low cost,non-toxicity,and natural abundance.However,their energy storage mechanism remains controversial due to their complicated electrochemical reactions.Meanwhile,to achieve satisfactory cyclic stability and rate performance of the Zn/MnO2 ZIBs,Mn2+ is introduced in the electrolyte(e.g.,ZnSO4 solution),which leads to more complicated reactions inside the ZIBs systems.Herein,based on comprehensive analysis methods including electrochemical analysis and Pourbaix diagram,we provide novel insights into the energy storage mechanism of Zn/MnO2 batteries in the presence of Mn2+.A complex series of electrochemical reactions with the coparticipation of Zn2+,H+,Mn2+,SO42-,and OH-were revealed.During the first discharge process,co-insertion of Zn2+ and H+ promotes the transformation of MnO2 into ZnxMnO4,MnOOH,and Mn2O3,accompanying with increased electrolyte pH and the formation of ZnSO4·3 Zn(OH)2-5 H2O.During the subsequent charge process,ZnxMnO4,MnOOH,and Mn2O3 revert to a-MnO2 with the extraction of Zn2+ and H+,while ZnSO4·3Zn(OH)2·5H2O reacts with Mn2+ to form ZnMn3O7·3 H2O.In the following charge/discharge processes,besides aforementioned electrochemical reactions,Zn2+ reversibly insert into/extract from α-MnO2,ZnxMnO4,and ZnMn3O7·3H2O hosts;ZnSO4·3Zn(OH)2·5 H2O,Zn2Mn3O8,and ZnMn2O4 convert mutually with the participation of Mn2+.This work is believed to provide theoretical guidance for further research on high-performance ZIBs. | Yongfeng Huang Jian Mou Wenbao Liu Xianli Wang Liubing Dong Feiyu Kang Chengjun Xu | 2019 | Nano-Micro Letters2019，11，3： | 11 |

| 3 | β-MnO_(2) with proton conversion mechanism in rechargeable zinc ion battery显示文摘Rechargeable aqueous zinc ion battery(RAZIB)is a promising energy storage system due to its high safety,and high capacity.Among them,manganese oxides with low cost and low toxicity have drawn much attention.However,the under-debate proton reaction mechanism and unsatisfactory electrochemical performance limit their applications.Nanorod b-MnO_(2) synthesized by hydrothermal method is used to investigate the reaction mechanism.As cathode materials for RAZIB,the Zn//b-MnO_(2) delivers 355 mA h g^(-1)(based on cathode mass)at0.1 A g^(-1),and retain 110 mA h g^(-1) after 1000 cycles at 0.2 A g^(-1).Different from conventional zinc ion insertion/extraction mechanism,the proton conversion and Mn ion dissolution/deposition mechanism of b-MnO_(2) is proposed by analyzing the evolution of phase,structure,morphology,and element of b-MnO_(2) electrode,the pH change of electrolyte and the determination of intermediate phase MnO OH.Zinc ion,as a kind of Lewis acid,also provides protons through the formation of ZHS in the proton reaction process.This study of reaction mechanism provides a new perspective for the development of Zn//MnO_(2) battery chemistry. | Wenbao Liu Xiaoyu Zhang Yongfeng Huang Baozheng Jiang Ziwen Chang Chengjun Xu Feiyu Kang | 2021 | Journal of Energy Chemistry2021，30，5： | 6 |
| 4 | Maternal supply of cysteamine alleviates oxidative stress and enhances angiogenesis in porcine placenta显示文摘Background:Oxidative stress in placenta is associated with the occurrence of adverse pregnancy outcomes in sow,but there are few satisfactory treatment strategies for these conditions.This study investigated the potential of cysteamine(CS)as an antioxidant protectant for regulating the reproductive performance,redox status,and placental angiogenesis of sows.Methods:The placental oxidative stress status and vascular density of piglets with different birth weights:<1.0 kg(low birth weight,LBW)and 1.4–1.6 kg(normal birth weight,NBW)were evaluated,followed by allotting 84 sows to four treatments(n=21)and feeding them with a basal diet supplemented with 0,100,300,or 500 mg/kg of CS from d 85 of gestation to d 21 of lactation,respectively.Placenta,serum,and colostrum samples of sows or piglets were collected,and the characteristics of sows and piglets were recorded.Furthermore,the in vivo results were validated using porcine vascular endothelial cells(PVECs).Results:Compared with the NBW placentae,the LBW placentae showed increased oxidative damage and were vulnerable to angiogenesis impairment.Particularly,H2O2-induced oxidative stress prompted intracellular reactive oxygen species generation and inhibited the tube formation and migration of PVECs as well as the expression of vascular endothelial growth factor-A(VEGF-A)in vitro.However,dietary CS supplementation can alleviate oxidative stress and improve the reproductive performance of sows.Specifically,compared with the control group,dietary 100 mg/kg CS could(1)decrease the stillbirth and invalid rates,and increase both the piglet birth weight in the low yield sows and the placental efficiency;(2)increase glutathione and reduce malondialdehyde in both the serum and the colostrum of sows;(3)increase the levels of total antioxidant capacity and glutathione in LBW placentae;(4)increase the vascular density,the mRNA level of VEGF-A,and the immune-staining intensity of platelet endothelial cell adhesion molecule-1 in the LBW placentae.Furthermore,the in vitro experiment indicated that CS pre-treatment could significantly reverse the NADPH oxidase 2-ROS-mediated inactivation of signal transducer and activator of transcription-3(Stat3)signaling pathway induced by H2O2 inhibition of the proliferation,tube formation,and migration of PVECs.Meanwhile,inhibition of Stat3 significantly decreased the cell viability,tube formation and the VEGF-A protein level in CS pretreated with H_(2)O_(2)-cultured PVECs.Conclusions:The results indicated that oxidative stress and impaired angiogenesis might contribute to the occurrence of LBW piglets during pregnancy,but CS supplementation at 100 mg/kg during late gestation and lactation of sows could alleviate oxidative stress and enhance angiogenesis in placenta,thereby increasing birth weight in low yield sows and reducing stillbirth rate.The in vitro data showed that the underlying mechanism for the positive effects of CS might be related to the activation of Stat3 in PVECs. | Shuangbo Huang Zifang Wu Zihao Huang Xiangyu Hao Longmiao Zhang Chengjun Hu Jianfu Wei Jinping Deng Chengquan Tan | 2022 | Journal of Animal Science and Biotechnology2022，13，1： | 4 |
| 5 | Effects of plant coverage on shrub fertile islands in the Upper Minjiang River Valley显示文摘The patchy distribution of vegetation in dry land results in well-documented 'fertile islands'. However, the response of shrub fertile islands to plant recovery and the underlying mechanisms, such as the linkage plant and soil properties, remain unknown.We sampled soils from areas with three different plant coverages(25%, 45%, and 75%) and three of their adjacent inter-plants to investigate soil physicochemical and microbial properties in the upper Minjiang River arid valley. The results showed that these factors were influenced by the persistence of plants that contrasted with the inter-plant interspaces. We found fertile islands in under-plant soil that were enhanced with increasing plant coverage, from 25% to 45% and 75%; however, there were no significant differences between 45% and 75% plant coverage apart from the soil clay content and the fungi to bacteria ratio. The soil microbial communities in under-plant soil were strongly influenced by the total soil carbon(TC), soil organic carbon(SOC),and available nitrogen(AN), whereas the microbial communities in inter-plant soil were primarily constrained by the AN and available phosphorous(AP). Moreover, the inter-plant soil properties, including gravimetric soil water content, pH, electrical conductivity(EC), and soil C:N ratio, were also strongly influenced by adjacent vegetation, which suggested that fertile islands may be beneficial for plant recovery in this region. | Laiye Qu Zhongbin Wang Yuanyuan Huang Yuxin Zhang Chengjun Song Keming Ma | 2018 | Science China(Life Sciences)2018，61，3： | 3 |
| 6 | Reactive MnO_(2) template-assisted synthesis of double-shelled PPy hollow nanotubes to boost microwave absorption显示文摘Microwave absorbing materials(MAMs)with wide effective absorption bandwidth(EAB)and low filling ratio are highly desirable for practical applications.Rational design in components and structures is one of the effective strategies to achieve MAMs with high performance.Herein,double-shelled hollow(DSH)polypyrrole(PPy)nanotubes were synthesized with hydrochloric acid(HCl)and sodium pstyrene sulfonate(SS)co-doping polymerization process using manganese dioxide(MnO_(2))nanorods as a self-sacrifice template.With the increase of HCl concentration,the 1D MnO_(2) core diminishes gradually to form the MnO_(2)@PPy coaxial nanostructures and finally the DSH PPy nanotube,which tunes the microwave absorption performance.Importantly,the DSH PPy nanotubes exhibit excellent microwave absorption of an optimal reflection loss of–50.4 dB and a wide EAB of 7.7 GHz with a low filling ratio of 5 wt%in a paraffin wax matrix.The excellent microwave absorption is believed to be mainly attributed to the enhanced synergistic effects of interfacial polarization and conduction loss arising from the unique DSH structure and the co-doping polymerization. | Huiling Gu Ji Huang Na Li Hua Yang Gang Chen Chengjun Dong Chunhong Gong Hongtao Guan | 2023 | Journal of Materials Science & Technology2023，，15： | 3 |
| 7 | Geochemical characteristics of hadal sediment in the northern Yap Trench显示文摘Two sediment cores were retrieved in the hadal zone of the Yap Trench,and their concentrations of six major elements Mg,Al,Ca,Ti,Mn and Fe and nine trace elements Sr,Ba,Pb,V,Cr,Co,Ni,Cu and Zn were determined in inductively coupled plasma atomic emission spectrometry(ICP-AES).According to the vertical distribution profiles of the 15 elements,the correlation of their concentrations,the ratios of Ni/Co,V/Cr,Fe/Al,and Ti/Al,and morphological characteristics of the sediment samples,the implications of the depositional environment and the sediment provenance were analyzed.The results show that the ratio of Ni/Co in all depths of the two sediment cores were below 5,and the ratio of V/Cr were lower than 2,indicating that the depositional environment of the hadal zone in the trench was oxidative and might have inflow of the Antarctic bottom oxygen-rich water.The sediment samples on the eastern side of the trench were siliceous mud mainly composed of diatoms,radiolarian,and sponge needles from surface to deep layer.The vertical profile of the elements,the concentration of TOC and the fossil record indicated that the sediment sample from station Dive113 was well mixed from surface to bottom layer.Based on the correlation of concentrations of the elements,the morphological characteristics of the sediment,and the ratios of Fe/Al and Ti/Al,we inferred that the sediment in the hadal zone of the trench had terrestrial,volcanic,biological,and authigenic sources.Major source of the sediment in the eastern side of the trench were terrestrial;whereas the sediment in the western side of the trench received more volcaniclastic input. | HUANG Yuhuan SUN Chengjun YANG Guipeng YUE Xin’an JIANG Fenghua CAO Wei YIN Xiaofei GUO Chaonan NIU Jiaohong DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 3 |
| 8 | Distribution characteristics of lipids in hadal sediment in the Yap Trench显示文摘In this study,cored sediment samples collected by the Jiaolong Submersible at 6779 m depth from the hadal zone of the Yap Trench in May 2016 were sliced in 1-cm interval from top to bottom,and lipids in each sediment layer were quantitatively and qualitatively analyzed.The vertical distribution profiles of the lipids in the sediment sample,their main existing forms,and their possible sources were investigated.The results show that the concentration of lipid in the surface sediment was the highest with the carbon number from 12 to 27,dominated by medium and short-chain lipids.The total concentration of fatty acids in surface sediment was much higher than those in the offshore and deep-sea areas,being up to 325.77μg/g due to the funnel effect caused by the“V”terrain of the trench.Fatty acid 18:0 was the most abundant lipids in the sediment sample.Abnormal high concentrations of fatty acid 18:1ω7 and alkanes indicated the existence of hydrothermal fluids in the study area.In addition,saturated fatty acids and monounsaturated fatty acids existed mainly in free form,and polyunsaturated fatty acids existed mainly in bound form.Most of the alkanes were in bound form,and their major source was autochthounous input.The carbon number of alcohols in the sediment sample ranged from 12 to 20,mainly existed in bound form.The source of fatty acids was mainly autochthonous input,and the neutral lipids had both marine and terrestrial origin.This is the first study of lipids in hadal sediment of the Yap Trench.The results will promote deeper understanding of organic carbon cycle in marine environment. | YAN Yixin SUN Chengjun HUANG Yuhuan CAO Wei JIANG Fenghua YANG Guipeng DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 2 |
| 9 | Research on data diagnosis method of acoustic array sensor device based on spectrogram显示文摘Acoustic array sensor device for partial discharge detection is widely used in power equipment inspection with the advantages of non-contact and precise positioning compared with partial discharge detection methods such as ultrasonic method and pulse current method.However,due to the sensitivity of the acoustic array sensor and the influence of the equipment operation site interference,the acoustic array sensor device for partial discharge type diagnosis by phase resolved partial discharge(PRPD)map might occasionally presents incorrect results,thus affecting the power equipment operation and maintenance strategy.The acoustic array sensor detection device for power equipment developed in this paper applies the array design model of equal-area multi-arm spiral with machine learning fast fourier transform clean(FFT-CLEAN)sound source localization identification algorithm to avoid the interference factors in the noise acquisition system using a single microphone and conventional beam forming algorithm,improves the spatial resolution of the acoustic array sensor device,and proposes an acoustic array sensor device based on the acoustic spectrogram.The analysis and diagnosis method of discharge type of acoustic array sensor device can effectively reduce the system misjudgment caused by factors such as the resolution of the acoustic imaging device and the time domain pulse of the digital signal,and reduce the false alarm rate of the acoustic array sensor device.The proposed method is tested by selecting power cables as the object,and its effectiveness is proved by laboratory verification and field verification. | Xing Lei Hang Ji Qiang Xu Ting Ye Shengfu Zhang Chengjun Huang | 2022 | Global Energy Interconnection2022，5，4： | 2 |
| 10 | Highly transmitted silver nanowires-SWCNTs conductive flexible film by nested density structure and aluminum-doped zinc oxide capping layer for flexible amorphous silicon solar cells显示文摘Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical transmittance between 600 and 1500 nm.In addition,the amorphous silicon photovoltaic devices with flexible ASA TCFs exhibited a power conversion efficiency(PCE)of 8.67%.After bending for 3000 times,the PCE was decreased to 8.20%,thereby demonstrating the potential of developed films to replace traditional ITO. | Shunliang Gao Xiaohui Zhao Qi Fu Tianchi Zhang Jun Zhu Fuhua Hou Jian Ni Chengjun Zhu Tiantian Li Yanlai Wang Vignesh Murugadoss Gaber A.M.Mersal Mohamed M.Ibrahim Zeinhom M.El-Bahy Mina Huang Zhanhu Guo | 2022 | Journal of Materials Science & Technology2022，，31： | 2 |
| 11 | Research on characteristics of acoustic signal of typical partial discharge models显示文摘The pulse current method,acoustic and ultrasonic partial discharge(PD)detection,and voiceprint PD detection are commonly used detection methods for the PD detection of power equipment.To study the characteristics of PD signals of typical discharge models based on the principles of the above three detection methods,an acoustic detection experimental system consisting of a needle-tip model and a surface model was built.Acoustic tests were carried out on needle-tip models with different curvature radii and surface discharge models with different lengths of conductive paste.The experimental results showed that acoustic and ultrasonic PD detection and voiceprint PD detection exhibited different sensitivities to the needle-tip discharge models,and the combination of acoustic and ultrasonic PD and voiceprint PD detection was more beneficial for the comprehensive detection of cable PD signals.Based on voiceprint recognition technology,this study drew FFT(Fast Fourier Transformation)diagrams of different types of PD acoustic signals and analyzed the differences in the ultrasonic signal frequency distribution.The frequency band of the voiceprint PD signal of the needle-tip discharge models was concentrated in the range 17-27 kHz,and the frequency band of the voiceprint PD signal of the conductive paste discharge models was concentrated in the range 20-25 kHz.The measurement of voiceprint PD signals in these frequency bands were strengthened when the PD of a cable was detected on-site,which provides the basis for the use of the cable model for on-site PD detection. | Hang Ji Xing Lei Qiang Xu Chengjun Huang Ting Ye Shangqing Yuan | 2022 | Global Energy Interconnection2022，5，1： | 1 |

| 13 | Synthesis and Room Temperature Ferromagnetism in Fe-Doped CuAlO_2 Semiconductor显示文摘The synthesis and characterization of Fe-doped CuAlO2 semiconductor were reported. The samples were synthesized by a simple and cost effective spin-on technique from solid state reaction of Cu2O and Al2O3 on sapphire (001) substrate. Appropriate ethyl-cellulose (EC) and terpineol are useful for the formation of Fe-doped CuAlO2 films. X-ray diffraction (XRD) revealed the growth of pure delafossite CuAlO2 phase ruled out elemental metallic Fe clusters in all the Fe incorporated CuAlO2 films. The existence of ferromagnetism at room temperature is evidenced by well-defined hysteresis loops. Specially, the saturation magnetization (Ms ) values at room temperature have been monotonously enhanced with the increase of Fe composition from 1% to 5%. | 陈晨 DONG Chengjun WANG Biao HUANG Jiangqiang 王一丁 | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，3： | 1 |
| 14 | Si nanowire Bio-FET for electrical and label-free detection of cancer cell-derived exosomes显示文摘Exosomes are highly important in clinical diagnosis due to their high homology with their parental cells.However,conventional exosome detection methods still face the challenges of expensive equipment,low sensitivity,and complex procedures.Field effect transistors(FETs)are not only the most essential electronic component in the modern microelectronics industry but also show great potential for biomolecule detection owing to the advantages of rapid response,high sensitivity,and label-free detection.In this study,we proposed a Si nanowire field-effect transistor(Si-NW Bio-FET)device chemically modified with specific antibodies for the electrical and label-free detection of exosomes.The Si-NW FETs were fabricated by standard microelectronic processes with 45 nm width nanowires and packaged in a polydimethylsiloxane(PDMS)microfluidic channel.The nanowires were further modified with the specific CD63 antibody to form a Si-NW Bio-FET.The use of the developed Si-NW Bio-FET for the electrical and labelfree detection of exosomes was successfully demonstrated with a limit of detection(LOD)of 2159 particles/mL.In contrast to other technologies,in this study,Si-NW Bio-FET provides a unique strategy for directly quantifying and realtime detecting exosomes without labeling,indicating its potential as a tool for the early diagnosis of cancer. | Wenjie Zhao Jiawei Hu Jinlong Liu Xin Li Sheng Sun Xiaofeng Luan Yang Zhao Shuhua Wei Mingxiao Li Qingzhu Zhang Chengjun Huang | 2022 | Microsystems & Nanoengineering2022，8，3： | 1 |
| 15 | Directional surface plasmon polariton scattering by single low-index dielectric nanoparticles:simulation and experiment显示文摘Directionally scattered surface plasmon polaritons(SPPs)promote the efficiency of plasmonic devices by limiting the energy within a given spatial domain,which is one of the key issues to plasmonic devices.Benefitting from the magnetic response induced in high-index dielectric nanoparticles,unidirectionally scattered SPPs have been achieved via interference between electric and magnetic resonances excited in the particles.Yet,as the magnetic response in low-index dielectric nanoparticles is too weak,the directionally scattered SPPs are hard to detect.In this work,we demonstrate forward scattered SPPs in single low-index polystyrene(PS)nanospheres.We numerically illustrate the excitation mechanism of plasmonic induced electric and magnetic multipole modes,as well as their contributions to forward SPP scattering of single PS nanospheres.We also simulate the SPP scattering field distribution obtaining a forward-to-backward scattering intensity ratio of 50.26:1 with 1μm PS particle.Then the forward scattered SPPs are experimentally visualized by Fourier transforming the real-space plasmonic imaging to k-space imaging.The forward scattered SPPs from low-index dielectric nanoparticles pave the way for SPP direction manipulation by all types of nanomaterials. | XUQING SUN HONGYAO LIU LIWEN JIANG RUXUE WEI CHANG WANG XUE WANG XIAOJUAN SUN FEI WANG XINCHAO LU ANDREY B.EVLYUKHIN CHENGJUN HUANG | 2023 | Photonics Research2023，11，5： | 1 |
| 16 | Vertical variations of dissolved carbohydrates in the North Yap Trench显示文摘The concentrations of dissolved monosaccharides(MCHO),polysaccharides(PCHO),and total carbohydrates(TCHO)in the seawater samples collected from the north of the Yap Trench in the western Pacific Ocean were measured by 2,4,6-tripyridine-s-triazine(TPTZ)spectrophotometry method.The results show that the concentrations of MCHO,PCHO,and TCHO ranged from 4.6 to 22.1μmol C/L,3.5 to 27.3μmol C/L,and 13.8 to 36.3μmol C/L,respectively.In different sampling stations,the concentrations of MCHO,PCHO,and TCHO with water depth showed complex variation patterns.In the study area,the maximum concentrations of MCHO,PCHO,and TCHO occurred in the euphotic layer and the minimum concentrations occurred in mesopelagic seawater layer.Generally,the concentrations of MCHO,PCHO,and TCHO decreased with water depth from the euphotic layer to the hadal zone.The average value of PCHO/TCHO was higher than the average value of MCHO/TCHO,indicating that PCHO was the main component of TCHO in north of the Yap Trench. | GUO Chaonan SUN Chengjun YANG Guipeng ZHANG Honghai CHEN Yan YIN Xiaofei JIANG Fenghua HUANG Yuhuan NIU Jiaohong DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 1 |
| 17 | Few-layer Ti3C2Tx MXene delaminated via flash freezing for high-rate electrochemical capacitive energy storage显示文摘Few-layer Ti3C2Tx MXene is synthesized from multi-layered Ti3C2Tx via a flash freezing-assisted delamination process.During the flash freezing process,the water molecules in the interlayers of multi-layered MXene are induced to rearrange and produce volume expansion,thus notably expand the MXenes’interlayer distance to form few-layer MXene.The synthesized few-layer Ti3C2Tx MXene nanosheets display a very small thickness(less than 5 Ti3C2 atom-layers)and expanded interlayer spacing.Consequently,the few-layer Ti3C2Tx exhibits enhanced capacitance(255 F g^-1 vs.177 F g^-1 for the multi-layered Ti3C2Tx)and significantly optimized rate capability(150 F g^-1 at 200 mV s^-1 vs.25 F g^-1 for the multi-layered Ti3C2Tx),because redox-active sites in the few-layer MXene are easily accessible to electrolyte ions.Moreover,an asymmetric supercapacitor is constructed using the few-layer Ti3C2Tx negative electrode and an activated carbon fiber positive electrode.The asymmetric supercapacitor presents a high energy density of 17.9 Wh kg^-1 and a high power density of 14 kW kg^-1,which is inseparable from its wide voltage window of 1.4 V and the good rate performance of the few-layer Ti3C2Tx MXene electrode.Overall,the flash freezing-assist delamination provides an effective and environmental-friendly strategy to synthesize few-layer MXene materials for high-rate electrochemical energy storage. | Xianli Wang Liubing Dong Wenbao Liu Yongfeng Huang Xuechao Pu Jinjie Wang Feiyu Kang Jia Lia Chengjun Xu | 2020 | Journal of Energy Chemistry2020，29，9： | 1 |

| 20 | 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 |
