| 1 | A human circulating immune cell landscape in aging and COVID-19显示文摘Age-associated changes in immune cells have been linked to an increased risk for infection.However,a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking.Here,we combined scRNA-seq,mass cytometry and sCATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19.We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector,cytotoxic,exhausted and reg-ulatory cells,along with increased late natural killer cells,age-associated B cells,inflammatory monocytes and age-associated dendritic cells.In addition,the expression of genes,which were implicated in coron-avirus susceptibility,was upregulated in a cell subtype-specific manner with age.Notably,COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senes-cence.Therefore,these findings suggest that a dysreg-ulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly. | Yingfeng Zheng Xiuxing Liu Wenqing Le Lihui Xie He Li Wen Wen Si Wang Shuai Ma Zhaohao Huang Jinguo Ye Wen Shi Yanxia Ye Zunpeng Liu Moshi Song Weiqi Zhang Jing-Dong J.Han Juan Carlos lzpisua Belmonte Chuanle Xiao Jing Qu Hongyang Wang Guang-Hui Liu Wenru Su | 2020 | Protein & Cell2020，11，10： | 10 |
| 2 | Optical sensors for power transformer monitoring:A review显示文摘Power transformers play a vital role in power transmission systems from the energy source to the consumption center.In situ diagnostics of the performance of power transformers provides a variety of benefits to ensure reliable electricity transmission.Immunity to electromagnetic interference,high sensitivity,high insulation as well as small dimensions of optical sensing make it very attractive for applications in power transformer monitoring.This paper presents a critical review of various diagnostic methods for power transformers such as partial discharge,dissolved gases,temperature and other important sensing,and optical detection.The advantages and disadvantages of different monitoring methods are carefully discussed and assessed.Finally,the existing technical barriers and future prospects of optical monitoring methods for power transformers are presented. | Guoming Ma Yuan Wang Weiqi Qin Hongyang Zhou Chao Yan Jun Jiang Yiguang Ju | 2021 | High Voltage2021，6，3： | 7 |
| 3 | Blue revolution for food security under carbon neutrality: A case from the water-saving and drought-resistance rice显示文摘The increasing concentration of greenhouse gases(GHGs)in Earth's atmosphere leads to global warming,which further causes a series of climate changes and does great harm to both human society and natural ecosystems.Agricultural GHG emissions,mainly in theform of methane(CH4)and nitrous oxide(N2O),areasignificantsourceofGHGs,accountingfor~14%total global GHGs(Zhang et al.,2022).One major source of agricultural GHGs is CH4 emissions from rice paddies,which is responsiblefor~10%-12%ofhuman-inducedCH4emissions(van Groenigen et al.,2013)and contributes~2.40%to the enhanced global warming effect(Zhang et al.,2022).The global warming potential of GHGs emissions from rice systems is roughly four times higher than either wheat or maize(Linquist et al.,2012). | Hui Xia Xianxian Zhang Yi Liu Junguo Bi Xiaosong Ma Anning Zhang Hongyan Liu Liang Chen Sheng Zhou Huan Gao Kai Xu Haibin Wei Guolan Liu Feiming Wang Hongyang Zhao Xingxing Luo Danping Hou Qiaojun Lou Fangjun Feng Liguo Zhou Shoujun Chen Ming Yan Tianfei Li Mingshou Li LeiWang Zaochang Liu Xinqiao Yu HanweiMei Lijun Luo | 2022 | Molecular Plant2022，15，9： | 3 |
| 4 | Strongly coupled Te-SnS_(2)/MXene superstructure with self-autoadjustable function for fast and stable potassium ion storage显示文摘Potassium-ion batteries(PIBs)are a promising candidate for next-generation electric energy storage applications because of the abundance and low cost of potassium.However,the development of PIBs is limited by sluggish kinetics and huge volume expansion of anodes,leading to poor rate capability and cycling stability.Herein,an advanced superstructure anode,including Te-doped SnS_(2) nanosheets uniformly anchored on MXene surface(Te-SnS_(2)/MXene),is rationally designed for the first time to boost K^(+)storage performance.Featuring with strong interface interaction and self-autoadjustable interlayer spacings,the Te-SnS_(2)/MXene can efficiently accelerate electron/ion transfer,accommodate volume expansion,inhibit crack formation,and improve pseudocapacitive contribution during cycling.Thus,the novel Te-SnS_(2)/MXene anode delivers a high reversible capacity(343.2 mAh g^(-1) after 50 cycles at0.2 A g^(-1)),outstanding rate capability(186.4 mAh g^(-1) at 20 A g^(-1)),long cycle stability(165.8 mAh g^(-1)after 5000 cycles at 10 A g^(-1) with a low electrode swelling rate of only 15.4%),and reliable operation in flexible full battery.The present Te-SnS_(2)/MXene becomes among the best transition metal-based anode materials for PIBs reported to date. | Hongyang Sun Yelong Zhang Xiaodan Xu Jianwen Zhou Fan Yang Hao Li Hao Chen Yucheng Chen Zheng Liu Zhenping Qiu Da Wang Lipo Ma Jiawei Wang Qingguang Zeng Zhangquan Peng | 2021 | Journal of Energy Chemistry2021，30，10： | 2 |
| 5 | Flashover Behavior of Cone-type Spacers with Inhomogeneous Temperature Distribution in SF_(6)/N_(2)-filled DC-GIL Under Lightning Impulse with DC Voltage Superimposed显示文摘Before designing DC gas insulated transmission lines(GIL),the insulation characteristics of spacers under a lightning impulse(LI)voltage with a superimposed DC voltage must be clarified.Many experiments have been performed to guide the development of the DC spacer.However,the impacts of thermal stresses on their insulation performance under combined voltage are always neglected,and little attention has been given to the insulation characteristics of spacers in an eco-friendly gas filled DC-GIL.To solve these problems,an experiment setup with the abilities to load the thermal field and the DC voltage with LI voltage superimposed on the cone-type spacer are built.After that,the insulation characteristics of spacers under the combined voltage of DC with lightning impulse at 0.1 MPa SF_(6)/N_(2) gas mixtures are investigated,under different thermal stress conditions.The experiment’s results indicate that:1)The flashover voltage of spacers under the same polarity superimposed voltages is slightly higher than that under LI alone.Conversely,the flashover voltage under reverse polarity superimposed voltages is lower than that under LI alone.2)The longer the duration of the foregoing DC voltage,the differences between the flashover voltage under superposed voltage and that under LI alone are larger.3)The combined flashover voltages are reduced under thermal stress.To ensure the insulation performance of newly designed DC spacers,the insulation test is suggested to be applied under thermal stress and combined voltage of the DC with lightning impulse,especially for superimposed reverse polarity. | Guoming Ma Hongyang Zhou Yuan Wang Hanchi Zhang Shijie Lu Youping Tu Jian Wang Chengrong Li | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 2 |
| 6 | All in one theranostic nanoplatform enables efficient anti-tumor peptide I delivery for triple-modal imaging guided cancer therapy显示文摘Developing a reliable system to efficiently and safely deliver peptide drugs into tumor tissues still remains a great challenge since the instability of peptide drugs and low ability to traverse the cell membrane. Herein, we constructed a multifunctional nanoplatform based on porous europium/gadolinium (Eu/Gd)-doped NaLa(MoO4)2 nanoparticles (NLM NPs) to deliver antitumor peptide of B-cell lymphoma/leukemia-2-like protein 11 (BIM) for cancer therapy. The porous NLM NPs exhibited inherent photoluminescent, magnetic and X-ray absorbable properties, which enable them for triple-modal bioimaging, including fluorescence, magnetic resonance imaging (MRI) and computed tomography (CT). This triple-modal bioimaging can contribute to monitoring NLM NPs biodistribution and guiding therapy in vitro and in vivo. Furthermore, the NLM NPs showed negligible cytotoxicity in vitro and tissue toxicity in vivo. Importantly, NLM NPs could load the antitumor peptide of BIM and efficiently improve the resistance of peptide drugs to proteolysis. The BIM peptide was efficiently delivered into the tumor cells by NLM NPs, which can inhibit the growth and promote the apoptosis of cancer cells in vitro, significantly inhibit the tumor growth in vivo. Notably, NLM-BIM theranostic nanoplatform exhibits low systemic toxicity and fewer side effects in vivo. The NLM NPs can serve as a promising multifunctional peptide delivery nanoplatform for multi-modal bioimaging and cancer therapy. | Xiaoyan Qu Zhengqing Liu Bohan Ma Na Li Hongyang Zhao Tian Yang Yumeng Xue Xiaozhi Zhang Yongping Shao Ying Chang Jun Xu Bo Lei Yaping Du | 2019 | Nano Research2019，12，3： | 2 |
| 7 | Review of flash sintering with strong electric field显示文摘Flash sintering is a novel field‐assisted sintering technology for ceramics that allows a dramatic reduction in processing time and temperature.Since 2010,when flash sintering was first reported,it has been a focus of research interest in the field of materials science.Recent study results have confirmed that the sintering temperature decreases with the strength of the applied electric field;for some ceramics,the sintering temperature can be lowered even to room temperature.This represents an innovative breakthrough for ceramic sintering at ultra‐low temperatures.However,once the electric field strength in flash sintering is increased,new questions and challenges arise,such as whether or not partial discharge occurs in the green body if under electro‐thermal coupling stress,how to quantitatively analyse the impact of discharge on sintering,and,moreover,whether the sintering mechanism under a strong electric field is consistent with that under a weak electric field.These research questions require knowledge of partial discharge detection,dielectric theory,and other topics that are beyond the scope of materials science.To address this need,this review summarises the work carried out in flash sintering with a strong electric field from the perspective of high voltage and insulation technology.First,the flash sintering process and mechanism are briefly introduced.Then,the published literature on flash sintering with a strong electric field for various ceramic materials is summarised in depth.In addition,experimental phenomena that are observed in flash sintering with a strong electric field,such as flash and blackening,are discussed.Finally,some suggestions for future work are presented.It is anticipated that the knowledge gap between different areas of study can be filled by this review. | Hongyang Zhou Xiang Li Yuchen Zhu Jieming Liu Angxuan Wu Guoming Ma Xilin Wang Zhidong Jia Liming Wang | 2022 | High Voltage2022，7，1： | 2 |
| 8 | High‐performance ZnO varistor ceramics prepared by arc‐induced flash sintering with low energy consumption at room temperature显示文摘The development of ultra‐high voltage transmission lines requires a ZnO arrester with excellent electrical response and high voltage gradient.Compared with conventional preparation methods,flash sintering allows fast production of novel high‐performance ZnO varistor ceramics with low energy consumption and controlled grain growth.Herein,ZnO varistor ceramics were prepared using the flash sintering method at an air pressure of 21 kPa for 60 s at 25℃.The results showed that the flash‐sintered samples had fine grains and reduced loss of volatile elements.Moreover,the voltage gradient,leakage current density,and non‐linear coefficient of the flash‐sintered varistor ceramics were significantly improved compared with those of conventionally sintered samples.Owing to the short preparation time and absence of a heating process,the energy consumption of the proposed flash sintering method was significantly reduced to 10%of that by conventional sintering.The proposed method is a promising approach for the preparation of ZnO arresters with excellent electrical properties and serves as an effective method that realises energy saving and emission reduction. | Angxuan Wu Zhixiang Zhu Xilin Wang Nianping Yan Hongyang Zhou Rongxia Huang Guoming Ma Zhidong Jia Liming Wang | 2022 | High Voltage2022，7，2： | 2 |
| 9 | A 2-step GPS carrier tracking loop for urban vehicle applications显示文摘Global positioning system(GPS) for vehicle applications in the urban area is challenged by low signal intensity. The carrier loop based on fast Fourier transform(FFT) can obtain a high signal to noise ratio(SNR) gain by increasing the observation time. However, this leads to a major problem that the acceleration cannot be ignored. The performance of the FFT-based loop will decline with the acceleration increasing. This paper discusses the effect of the dynamic on FFT first. Then a high performance carrier tracking loop for weak GPS L5 signals is proposed. It combines discrete chirp-Fourier transform(DCFT) and the phase fitting method to estimate Doppler frequency and Doppler rate simultaneously.First, a sequence of integration results is used to perform DCFT to estimate coarse Doppler frequency and Doppler rate. Second, the phase of the sequence is calculated and used to perform linear fitting. By the phase fitting method, the fine Doppler frequency and Doppler rate can be estimated. The computation cost is small because the integration results are used and the phase fitting method needs only coarse estimates of Doppler frequency and Doppler rate. Compared with FFT and DCFT, the precision of the phase fitting method is not limited by the resolution. Thus the proposed loop can get high precision and low carrier to noise ratio(C/N0) tracking threshold. Simulation results show this loop has a great improvement than conventional loops for urban weak-signal applications. | Hongyang Zhang Luping Xu Yue Jian Xiaochen Ma | 2017 | Journal of Systems Engineering and Electronics2017，28，5： | 1 |

| 11 | Electrospun Nanofibrous Adsorption Membranes for Wastewater Treatment:Mechanical Strength Enhancement显示文摘Functional nanofibrous membranes fabricated by electrospinning technology have attracted much attention in the removal of heavy metal ions from contaminated wastewater.The high specific surface area,high porosity and ease of functionality create an enhanced throughput and high adsorption capacity of the nanofibrous membrane.However,the relatively poor mechanical properties of the membrane with a non-woven nanofibrous structure are one of the major concerns,which can limit the applications in wastewater treatment.Different strategies and methodologies were explored to address the problems and were reviewed in this work,highlighting the possibilities of overcoming the poor mechanical properties of the nanofibrous membrane and to ensure the recyclability and reusability of the membrane during the adsorption process. | XIN Rui MA Hongyang Shyam Venkateswaran Benjamin S.Hsiao | 2021 | Chemical Research in Chinese Universities2021，37，3： | 1 |

| 13 | A convenient method for the determination of molecular weight cut-off of ultrafiltration membranes显示文摘With the rapid increase of water contamination,membrane separation technology and their corresponding molecular weight cut-off(MWCO) evaluation method become more necessary.In this study,Panax notoginseng saponins was used as a new standard marker to determinate ultrafiltration(UF) membrane MWCOs,series of Millipore membranes were selected as control group to analyze and calculate the relationship between retention rate and MWCOs with exponential or logarithmic equation.A new and convenient method was provided for determining the membrane MWCO by modeling analysis retention rate with MWCOs,and the regression coefficients >0.990.The feasibility and practicability of established method was verified by different manufactures' membrane and dextrans.In the detection progress,as the main ingredient of Panax notoginseng saponins,Notoginsenoside R_1,Ginsenoside Rg_1,Ginsenoside Rb_1 and Ginsenoside Rd with different surface activity,the MWCO range of UF membranes can be divided into two zones mainly due to the retention rate difference among Notoginsenoside R_1,Ginsenoside Rg_1,Ginsenoside Rb_1 and Ginsenoside Rd.Zone 1,1000-10000;and Zone II,10000-100000.Thus,the new method would be helpful to improve the applicability of UF membrane in separation technology. | Cunyu Li Yun Ma Hongyang Li Guoping Peng | 2017 | Chinese Journal of Chemical Engineering2017，25，1： | 1 |

| 15 | Direct laser writing breaking diffraction barrier based on two-focus parallel peripheralphotoinhibition lithography显示文摘Direct laser writing(DLW)enables arbitrary three-dimensional nanofabrication.However,the diffraction limit poses a major obstacle for realizing nanometer-scale features.Furthermore,it is challenging to improve the fabrication efficiency using the currently prevalent single-focal-spot systems,which cannot perform high-throughput lithography.To overcome these challenges,a parallel peripheral-photoinhibition lithography system with a sub-40-nm two-dimensional feature size and a sub-20-nm suspended line width was developed in our study,based on two-photon polymerization DLW.The lithography efficiency of the developed system is twice that of conventional systems for both uniform and complex structures.The proposed system facilitates the realization of portable DLW with a higher resolution and throughput. | Dazhao Zhu Liang Xu Chenliang Ding Zhenyao Yang Yiwei Qiu Chun Cao Hongyang He Jiawei Chen Mengbo Tang Lanxin Zhan Xiaoyi Zhang Qiuyuan Sun Chengpeng Ma Zhen Wei Wenjie Liu Xiang Fu Cuifang Kuang Haifeng Li Xu Liu | 2022 | Advanced Photonics2022，4，6： | 1 |
