| 3 | The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence. | Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 14 |
| 4 | SnS_2@C Hollow Nanospheres with Robust Structural Stability as High?Performance Anodes for Sodium Ion Batteries显示文摘Constructing unique and highly stable structures with plenty of electroactive sites in sodium storage materials is a key factor for achieving improved electrochemical properties through favorable sodium ion di usion kinetics. An SnS_2@carbon hollow nanospheres(SnS_2@C) has been designed and fabricated via a facile solvothermal route, followed by an annealing treatment. The SnS_2@C hybrid possesses an ideal hollow structure, rich active sites, a large electrode/electrolyte interface, a shortened ion transport pathway, and, importantly, a bu er space for volume change, generated from the repeated insertion/extraction of sodium ions. These merits lead to the significant reinforcement of structural integrity during electrochemical reactions and the improvement in sodium storage properties, with a high specific reversible capacity of 626.8 mAh g^(-1) after 200 cycles at a current density of 0.2 A g^(-1) and superior high-rate performance(304.4 mAh g^(-1) at 5 A g^(-1)). | Shuaihui Li Zhipeng Zhao Chuanqi Li Zhongyi Liu Dan Li | 2019 | Nano-Micro Letters2019，11，1： | 8 |
| 5 | Rapid on-line non-destructive detection of the moisture content of corn ear by bioelectrical impedance spectroscopy显示文摘Moisture content of corn directly affects its quality and storage time,and the rapid on-line detection of the moisture content of corn ears not threshed or in vivo in the fields is required.Because of the special shape of corn ear,the rapid,low cost and non-destructive bioelectrical impedance measurement is more suitable for its moisture content detection.Using the four-electrode method with the Agilent E4980A precision LCR meter,the electrical impedance spectroscopies of the sweet corn ears and waxy corn ears at different moisture contents were acquired.The frequency range of the detection was from 20 Hz to 2 MHz and to enhance the contact,the attached-type electrodes were wrapped in cotton soaked with 0.1%NaCl solution.The impedance data over the frequency range from 300 Hz to 5 kHz were used to obtain the parameters of the bio-impedance Cole-Cole model.The results showed a good linear correlation(coefficient of determination R2=0.960)between the equivalent parallel resistance R∞of sweet corn ear and the moisture content value determined by standard chemical method.The research proved that the bioelectrical impedance spectroscopy can be used for detecting the moisture content of corn ear. | Zhao Pengfei Zhang Hanlin Zhao Dongjie Wang Zhijie Fan Lifeng Huang Lan Ma Qin Wang Zhongyi | 2015 | International Journal of Agricultural and Biological Engineering2015，8，6： | 3 |
| 6 | Self-Healing Liquid Metal Magnetic Hydrogels for Smart Feedback Sensors and High-Performance Electromagnetic Shielding显示文摘Hydrogels exhibit potential applications in smart wearable devices because of their exceptional sensitivity to various external stimuli.However,their applications are limited by challenges in terms of issues in biocompatibility,custom shape,and self-healing.Herein,a conductive,stretchable,adaptable,self-healing,and biocompatible liquid metal GaInSn/Ni-based composite hydrogel is developed by incorporating a magnetic liquid metal into the hydrogel framework through crosslinking polyvinyl alcohol(PVA)with sodium tetraborate.The excellent stretchability and fast self-healing capability of the PVA/liquid metal hydrogel are derived from its abundant hydrogen binding sites and liquid metal fusion.Significantly,owing to the magnetic constituent,the PVA/liquid metal hydrogel can be guided remotely using an external magnetic field to a specific position to repair the broken wires with no need for manual operation.The composite hydrogel also exhibits sensitive deformation responses and can be used as a strain sensor to monitor various body motions.Additionally,the multifunctional hydrogel displays absorption-dominated electromagnetic interference(EMI)shielding properties.The total shielding performance of the composite hydrogel increases to~62.5 dB from~31.8 dB of the pure PVA hydrogel at the thickness of 3.0 mm.The proposed bioinspired multifunctional magnetic hydrogel demonstrates substantial application potential in the field of intelligent wearable devices. | Biao Zhao Zhongyi Bai Hualiang Lv Zhikai Yan Yiqian Du Xiaoqin Guo Jincang Zhang Limin Wu Jiushuai Deng David Wei Zhang Renchao Che | 2023 | Nano-Micro Letters2023，15，6： | 3 |
| 7 | Aqueous Self-Assembly of Block Copolymers to Form Manganese Oxide-Based Polymeric Vesicles for Tumor Microenvironment-Activated Drug Delivery显示文摘Molecular self-assembly is crucially fundamental to nature.However,the aqueous self-assembly of polymers is still a challenge.To achieve self-assembly of block copolymers [(polyacrylic acid-block-polyethylene glycol-block-polyacrylic acid(PAA68-b-PEG86-b-PAA68)] in an aqueous phase,manganese oxide(MnO2) is first generated to drive phase separation of the PAA block to form the PAA68-b-PEG68-b-PAA68/MnO2 polymeric assembly that exhibits a stable structure in a physiological medium.The polymeric assembly exhibits vesicular morphology with a diameter of approximately 30 nm and high doxorubicin(DOX) loading capacity of approximately 94%.The transformation from MnO2 to Mn2+caused by endogenous glutathione(GSH)facilitates the disassembly of PAA68-b-PEG68-b-PAA68/MnO2 to enable its drug delivery at the tumor sites.The toxicity of DOXloaded PAA68-b-PEG68-b-PAA69/MnO2 to tumor cells has been verified in vitro and in vivo.Notably,drug-loaded polymeric vesicles have been demonstrated,especially in in vivo studies,to overcome the cardiotoxicity of DOX.We expect this work to encourage the potential application of polymer self-assembly. | Yalei Miao Yudian Qiu Mengna Zhang Ke Yan Panke Zhang Siyu Lu Zhongyi Liu Xiaojing Shi Xubo Zhao | 2020 | Nano-Micro Letters2020，12，9： | 2 |

| 9 | Multiplex genome editing using a dCas9-cytidine deaminase fusion in Streptomyces显示文摘CRISPR/Cas-mediated genome editing has greatly facilitated the study of gene function in Streptomyces. However, it could not be efficiently employed in streptomycetes with low homologous recombination(HR) ability. Here, a deaminase-assisted base editor d Cas9-CDA-ULstr was developed in Streptomyces, which comprises the nuclease-deficient Cas9(dCas9), the cytidine deaminase from Petromyzon marinus(PmCDA1), the uracil DNA glycosylase inhibitor(UGI) and the protein degradation tag(LVA tag). Using d Cas9-CDA-ULstr , we achieved single-, double-and triple-point mutations(cytosine-to-thymine substitutions)at target sites in Streptomyces coelicolor with efficiency up to 100%, 60% and 20%, respectively. This base editor was also demonstrated to be highly efficient for base editing in the industrial strain, Streptomyces rapamycinicus, which produces the immunosuppressive agent rapamycin. Compared with base editors derived from the cytidine deaminase rAPOBEC1, the PmCDA1-assisted base editor dCas9-CDA-ULstr could edit cytosines preceded by guanosines with high efficiency, which is a great advantage for editing Streptomyces genomes(with high GC content). Collectively, the base editor dCas9-CDA-ULstr could be employed for efficient multiplex genome editing in Streptomyces. Since the d Cas9-CDA-ULstr -based genome editing is independent of HR-mediated DNA repair, we believe this technology will greatly facilitate functional genome research and metabolic engineering in Streptomyces strains with weak HR ability. | Yawei Zhao Jinzhong Tian Guosong Zheng Jun Chen Chuanwen Sun Zhongyi Yang Andrei A.Zimin Weihong Jiang Zixin Deng Zhijun Wang Yinhua Lu | 2020 | Science China(Life Sciences)2020，63，7： | 2 |

| 11 | Highly crystalline acceptor materials based on benzodithiophene with different amount of fluorine substitution on alkoxyphenyl conjugated side chains for organic photovoltaics显示文摘Organic solar cells based on narrow bandgap small-molecule acceptors(SMAs)with highly crystalline characteristics have attracted great attentions for their superiority in obtaining high photovoltaic efficiency.Employing highly crystalline SMAs to enhance power conversion efficiencies(PCEs)by regulating and controlling morphology and compatibility of donor and acceptor materials has turned out to be an effective approach.In this study,we synthesized three different crystalline SMAs by using fluorine substitution on alkoxyphenyl conjugated side chains to modulate the relationship of crystallinity and morphologies,namely ZY1(zero F atoms),ZY2(two F atoms),and ZY3(four F atoms).The three SMAs show the broad absorption edges and similar frontier orbital energy levels,generating the analogical(over 0.9 V)open circuit voltage(VOC)of the polymer solar cells(PSCs).As a result,the PM6:ZY2-based PSCs yield a PCE of 10.81%with a VOC of 0.95 V,a short-circuit current density(JSC)of 16.154 mA cm^(-2),and a fill factor(FF)of 0.71,which is higher than that of 9.17%(PM6:ZY1)and 6.37%(PM6:ZY3).And the PCE(17.23%)of the PM6:Y6:ZY2 based ternary PSCs is also higher than that of 16.32%PM6:Y6 based binary device.Obviously,the results demonstrate that adding fluorine atoms on the conjugated side chains to construct high crystalline materials is a positive strategy to effectively increase the efficiencies of binary and ternary PSCs. | Youdi Zhang Ruijie Ma Yong Wang Ying Wang Tao Liu Yiqun Xiao Yongjoon Cho Zhenghui Luo Xinhui Lu Lun Zhao Zhongyi Yuan Changduk Yang He Yan Yiwang Chen | 2021 | Materials Reports(Energy)2021，1，4： | 1 |

| 14 | Rapid and sensitive method for determining free amino acids in plant tissue by high-performance liquid chromatography with fluorescence detection显示文摘This paper describes a reliable and rapid method for the complete separation and quantitation of twenty-five amino acids typically found in plants, based on reversed phase high-performance liquid chromatography–linked fluorescence detector using a 150×4.6 mm Zorbax Eclipse AAA column. Plant tissue free amino acids(FAA)were extracted by ultrasonication with 5%(v/v) aqueous trifluoroacetic acid followed by ultrafiltration of extracts.The following analysis of amino acids was performed through programmed precolumn derivatization with orthophthalaldehyde and 9-fluorenylmethyl chloroformate reagents and efficient elution of derivatives within 26 min using binary gradient scheme. The method was validated over a concentration range of 4.5–450 μmol L^(-1)(μM).Separation analysis showed good selectivity(resolution>1.5) for most amino acids. The average repeatability(RSD%, relative standard deviation) of the analysis at seven calibration concentrations was below 4% and ranged from 1.13% to 12.04%. The intra-day mean coefficient of variation at two concentrations(22.5 and 90 μM) was within 2%, and the intermediate precision was less than 4%. The limits of detection were between 0.012 and 6.68 μM. The coefficients of determination(R2) of the linear calibration curves were from 0.9989 to 0.9999.When the method was applied to plant samples, the FAA recoveries at two spiked levels(25 and 100 μM) ranged from 67.0% to 108.9% with an average of 94.4%, and the precision was 0.26%–12.31% RSD. A specific application combining this method with optimized extraction and interference removal procedures was successfully used to determine the FAA pools in different plant tissues. Finally,a PLS-DA multivariate statistics model was validated for the classification of three plant species according to their FAA profiles. | Nengjian Zheng Huayun Xiao Zhongyi Zhang Xiaofei Gao Jingjing Zhao | 2017 | Acta Geochimica2017，36，4： | 1 |

| 17 | The clinical efficacy of percutaneous ethanol-lipiodol injection(PEI)combined with high-intensity focused ultrasound(HIFU)for small hepatocellularcarcinoma in special or high-risk locations显示文摘Objective The objective of this study was to explore the short-term effects and postoperative complications of ultrasound-guided percutaneous ethanol-lipiodol injection(PEI)combined with high-intensity focused ultrasound(HIFU)for the treatment of small hepatocellular carcinoma in a special or high-risk location.Methods Forty patients with small liver cancer in a special or high-risk location were randomly divided into two groups:20 patients were treated with PEI combined with HIFU(P+H group),and 20 patients were treated with HIFU alone(H group).There were no significant differences in average age,liver function,tumor location,tumor number,or tumor size between the two groups(P>0.05).Results Significant differences were observed in ablation parameters between the two groups(P<0.05).Under the same power,ablation rates of the P+H group were significantly higher than those in the H group,and postoperative complications in the P+H group were significantly lower than those in the H group(P<0.05).Conclusion The combination of PEI and HIFU has better clinical value than HIFU alone for small-cell liver cancer in special or high-risk locations. | Xiaoli Zou Changzhi Zhao Tao Wang Li Jia Zhongyi Feng Xiaoguang Wang Lei Wei Xiaobei Liu | 2021 | Oncology and Translational Medicine2021，7，4： | 1 |
| 18 | Aqueous Two-Phase Interfacial Assembly of COF Membranes for Water Desalination显示文摘Aqueous two-phase system features with ultralow interfacial tension and thick interfacial region,affording unique confined space for membrane assembly.Here,for the first time,an aqueous two-phase interfacial assembly method is proposed to fabricate covalent organic framework(COF)membranes.The aqueous solution containing polyethylene glycol and dextran undergoes segregated phase separation into two water-rich phases.By respectively distributing aldehyde and amine monomers into two aqueous phases,a series of COF membranes are fabricated at water-water interface.The resultant membranes exhibit high NaCl rejection of 93.0-93.6% and water permeance reaching 1.7-3.7 L m^(−2) h^(−1) bar^(−1),superior to most water desalination membranes.Interestingly,the interfacial tension is found to have pronounced effect on membrane structures.The appropriate interfacial tension range(0.1-1.0 mN m^(−1))leads to the tight and intact COF membranes.Furthermore,the method is extended to the fabrication of other COF and metal-organic polymer membranes.This work is the first exploitation of fabricating membranes in all-aqueous system,confering a green and generic method for advanced membrane manufacturing. | Hongjian Wang Jiashuai Zhao Yang Li Yu Cao Ziting Zhu Meidi Wang Runnan Zhang Fusheng Pan Zhongyi Jiang | 2022 | Nano-Micro Letters2022，14，12： | 1 |
| 19 | Three new MOFs with unusual Cu_6~Ⅱcluster, linear Cu~Ⅱ chain and triangular Cu_3~Ⅱcore motifs tuned by sulfonate group: Synthesis, structures and magnetic properties显示文摘Three new MOFs with the same components but different structures and magnetic behavior, {[Cu6(atr)6(H2O)2(μ3 OH)2(SO4)5 ]·5.25H2O} n (1), {[Cu2(atr)2( -OH)2(SO4 )]·3H2O} n (2), and {[Cu7(atr)6(H2O)6(μ3-OH)2(SO4 )6 ]·2H2O} n (3) (atr = 4-amino-1,2,4-triazole), were respectively synthesized by diffusion reactions in the presence of different structure-directing agents. Complex 1 is a slightly spin-frustrated antiferromagnetic layer with sulfonate aggregated CuⅡ6 clusters periodically extended by ditopic sulfonate linkers. 2 is a grid-based coplanar sheet with hydroxyl group bridgedCuOCulinear-chain interlinked by pairs of μ3 -atr ligands, exhibiting strong antiferromagnetic interactions to lead to an S = 0 spin ground state at low temperature. In contrast, air-instable 3 has a ladder-like broad-ribbon structure constructed from triangular CuⅡ3 cores and centrosymmetric CuⅡ1 octahedra. Obviously, the variable CuⅡ -ligand connectivity and the involving magnetic properties are significantly dominated by the cooperative and variable binding modes of the mixed sulfonate-atr ligands and bi-/tridentate bridging hydroxyl heterobridges. | YANG EnCui WANG XiuGuang ZHANG CuiHua YANG Na LIU ZhongYi ZHAO XiaoJun | 2013 | Science China Chemistry2013，56，4： | 1 |
