| 1 | Commissioning progress of the FAST显示文摘The Five-hundred-meter Aperture Spherical radio Telescope(FAST) was completed with its main structure installed on September 25, 2016, after which it entered the commissioning phase. This paper aims to introduce the commissioning progress of the FAST over the past two years. To improve its operational reliability and ensure effective observation time, FAST has been equipped with a real-time information system for the active reflector system and hierarchical commissioning scheme for the feed support system, which ultimately achieves safe operation of the two systems. For meeting the high-performance indices, a highprecision measurement system was set up based on the effective control methods that were implemented for the active reflector system and feed support system. Since the commissioning of the FAST, a low-frequency ultra-wideband receiver and 19-beam1.05-1.45 GHz receiver have been mainly used. Telescope efficiency, pointing accuracy, and system noise temperature were completely tested and ultimately achieved the acceptance indices of the telescope. The FAST has been in the process of national acceptance preparations and has begun to search for pulsars. In the future, it will still strive to improve its capabilities and expand its application prospects. | Peng Jiang YouLing Yue HengQian Gan Rui Yao Hui Li GaoFeng Pan JingHai Sun DongJun Yu HongFei Liu NingYu Tang Lei Qian JiGuang Lu Jun Yan Bo Peng ShuXin Zhang QiMing Wang Qi Li Di Li | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，5： | 11 |
| 2 | Synthesis of a novel illite@carbon nanocomposite adsorbent for removal of Cr(Ⅵ)from wastewater显示文摘A novel illite@carbon(I@C) nanocomposite adsorbent has been synthesized via a facile hydrothermal carbonization process(HTC) using glucose as carbonaceous source and illite as the carrier.The morphology,microstructure and surface properties of the prepared nanocomposite adsorbent were analyzed by FESEM,TGA,XRD,FT-IR and Zeta potential measurements.Batch experiments were carried out on the adsorption of Cr(Ⅵ) to determine the adsorption properties of the composite.The adsorption of Cr(Ⅵ) onto the I@C nanocomposite was well described by the pseudo-second-order kinetic model and Langmuir isotherm.Compared with the illite and carbon material(SC) separately,the prepared I@C nanocomposite adsorbent exhibited enhanced adsorption performance for Cr(Ⅵ) with a maximum adsorption capacity of 149.25 mg/g,which was higher than that of most reported adsorbents.In addition,the adsorption process was spontaneous and endothermic based on the adsorption thermodynamics study.The adsorption of Cr(Ⅵ) by I@C was highly p H-dependent and the optimum adsorption occurred at p H 2.0.The Zeta potential analysis results indicated that the electrostatic interactions between anionic Cr(Ⅵ) and the positively charged surface of the adsorbent might be critical to the adsorption mechanism.This study demonstrated that the I@C nanocomposite should be a promising candidate for a low-cost,environmental friendly and highly efficient adsorbent for the removal of toxic Cr(Ⅵ) from wastewater. | Gaofeng Wang Shan Wang Wen Sun Zhiming Sun Shuilin Zheng | 2017 | Journal of Environmental Sciences2017，29，7： | 7 |
| 3 | Pulsed electrohydrodynamic printing of conductive silver patterns on demand显示文摘Pulsed electrohydrodynamic printing(EHDP) is used to fabricate conductive silver patterns with micrometer resolution.The silver ink pendant experiences swelling,pulsation,and ejection under an applied pulse voltage of 20 Hz.The droplet deposition frequency is equal to the applied voltage frequency so that the EHDP can deposit silver ink on demand.A low applied voltage favors uniform and non-scattering silver patterns while a high applied voltage results in ink scattering.Discrete droplets with 45-55 m in diameter and continuous tracks with 60 m in width are generated by using a 110-m-cailber nozzle.The feature size of deposited patterns is about half of the nozzle caliber,and a finer resolution can be achieved with the introduction of smaller nozzle calibers.Furthermore,the appropriate curing condition is investigated for sufficient combustion of ink solvent.The minimum resistivity of 3.3 cm is demonstrated for a continuous track cured at 200°C for 10 min.Eventually,several passive electrical components,such as coated resistors,interdigitated capacitors(6 pF),and spiral inductors(0.6 H),are successfully fabricated. | WANG Xiangt XU Lei ZHENG GaoFeng CHENG Wei SUN DaoHeng | 2012 | Science China(Technological Sciences)2012，55，6： | 4 |
| 4 | A Predictive 6G Network with Environment Sensing Enhancement:From Radio Wave Propagation Perspective显示文摘In order to support the future digital society,sixth generation(6G)network faces the challenge to work efficiently and flexibly in a wider range of scenarios.The traditional way of system design is to sequentially get the electromagnetic wave propagation model of typical scenarios firstly and then do the network design by simulation offline,which obviously leads to a 6G network lacking of adaptation to dynamic environments.Recently,with the aid of sensing enhancement,more environment information can be obtained.Based on this,from radio wave propagation perspective,we propose a predictive 6G network with environment sensing enhancement,the electromagnetic wave propagation characteristics prediction enabled network(EWave Net),to further release the potential of 6G.To this end,a prediction plane is created to sense,predict and utilize the physical environment information in EWave Net to realize the electromagnetic wave propagation characteristics prediction timely.A two-level closed feedback workflow is also designed to enhance the sensing and prediction ability for EWave Net.Several promising application cases of EWave Net are analyzed and the open issues to achieve this goal are addressed finally. | Gaofeng Nie Jianhua Zhang Yuxiang Zhang Li Yu Zhen Zhang Yutong Sun Lei Tian Qixing Wang Liang Xia | 2022 | China Communications2022，19，6： | 4 |

| 7 | In situ formation of ionically conductive nanointerphase on Si particles for stable battery anode显示文摘Silicon(Si)is a promising anode candidate for next-generation lithium-ion batteries(LIBs)due to its high theoretical capacity.Solar Si photovoltaic waste possesses good purity and high output.Using it as the raw material for battery anodes can synchronously solve the problem of solid waste pollution and enable high energy density LIBs.A critical issue impeding the practical application of Si is the undesirable side reactions at the electrolyte-particle interface and the resulting increase in impedance during cycling.Herein,a Si-P core shell structure with chemical bonding at the Si-P interface is fabricated through a simple mechanical alloying reaction between red P and solar Si photovoltaic waste.The P nanoshell with thickness within 15 nm converts to Li3P during the initial lithiation process and maintains its phase on cycling.The as-formed Li3P nanolayer functions as a stable,ionically conductive protective layer that reduces the direct contact between Si and electrolytes,and thus suppresses undesired side reactions.The Si-P nanocomposite exhibits stable electrochemical cycling with a high reversible capacity of 1,178 mAh g^(−1)after 500 cycles at 1,200 mA g^(−1),as well as excellent rate capability(912 mAh g^(−1)at 2 C).With 15 wt%addition to graphite,a graphite/Si-P hybrid electrode shows a high overall reversible specific capacity of 447 mAh g^(−1)and 88.3%capacity retention after 100 cycles at high areal capacity of 2.64 mAh cm^(−2) at 100 mA g^(−1),indicating its promise as a drop-in anode in practical LIBs. | Xiaoxue Chen Gaofeng Ge Wenyu Wang Bao Zhang Jianjun Jiang Xuelin Yang Yuzhang Li Li Wang Xiangming He Yongming Sun | 2021 | Science China Chemistry2021，64，8： | 2 |
| 8 | Effects of dynamic deformation of pendant water drops on the electric field between hollow porcelain insulator sheds under extreme rainfall显示文摘Hollow porcelain insulators in substations are frequently confronted with rain flashovers under extreme rainfall.This study aims to investigate the spatial and temporal variation of electric fields between hollow porcelain insulator sheds affected by dynamic deformation of pendant water drops and effects of the dimensionless number of fluids,the Weber number(We)and the electric Bond number(BoE),on it for influencing factors'analysis.Flow‐electric field coupling simulations were carried out to compute the magnitude and the position of AC electric fields between the sheds.The results show that the maximum electric field at a point in time(Etmax)increases significantly after the breakup of the pendant water drop,and its position alters accordingly.For low We and BoE,the global maximum electric field(Egmax)increases with increasing We and BoE,respectively.It is much closer to the adjacent sheds and occurs later than Etmax at the breakup of the pendant water drop(Ebmax).By contrast,Egmax decreases in different degrees at high We and BoE,respectively.There is little difference between Egmax and Ebmax in the position and the occurring time.The influence mechanism on the maximum electric field and discharges and the relationship between discharges induced by the pendant water drop and rain flashover are discussed. | Yijie Sun Lin Yang Gaofeng Shang Zhiqiang Kuang Yifan Liao Yanpeng Hao Licheng Li | 2022 | High Voltage2022，7，1： | 2 |

| 18 | Highly Flexible and Broad‑Range Mechanically Tunable All‑Wood Hydrogels with Nanoscale Channels via the Hofmeister Effect for Human Motion Monitoring显示文摘Wood-based hydrogel with a unique anisotropic structure is an attractive soft material,but the presence of rigid crystalline cellulose in natural wood makes the hydrogel less flexible.In this study,an all-wood hydrogel was constructed by cross-linking cellulose fibers,polyvinyl alcohol(PVA)chains,and lignin molecules through the Hofmeister effect.The all-wood hydrogel shows a high tensile strength of 36.5 MPa and a strain up to~438%in the longitudinal direction,which is much higher than its tensile strength(~2.6 MPa)and strain(~198%)in the radial direction,respectively.The high mechanical strength of all-wood hydrogels is mainly attributed to the strong hydrogen bonding,physical entanglement,and van der Waals forces between lignin molecules,cellulose nanofibers,and PVA chains.Thanks to its excellent flexibility,good conductivity,and sensitivity,the all-wood hydrogel can accurately distinguish diverse macroscale or subtle human movements,including finger flexion,pulse,and swallowing behavior.In particular,when“An Qi”was called four times within 15 s,two variations of the pronunciation could be identified.With recyclable,biodegradable,and adjustable mechanical properties,the all-wood hydrogel is a multifunctional soft material with promising applications,such as human motion monitoring,tissue engineering,and robotics materials. | Guihua Yan Shuaiming He Gaofeng Chen Sen Ma Anqi Zeng Binglin Chen Shuliang Yang Xing Tang Yong Sun Feng Xu Lu Lin Xianhai Zeng | 2022 | Nano-Micro Letters2022，14，5： | 0 |
| 19 | Multifunctional Gd-CuS loaded UCST polymeric micelles for MR/PA imaging-guided chemo-photothermal tumor treatment显示文摘Hepatocellular carcinoma(HCC)is a life-threatening disease for which there is no effective treatment currently.Novel theranostics simultaneously having excellent imaging and therapeutic functions are highly desired in cancer therapy.Herein,we develop the sialic acid(SA)modified polymeric micelles at an upper critical solution temperature(UCST)of 43℃(sialic acid-poly(ethylene glycol)-poly(acrylamide-co-acrylonitrile),SA-PEG-p(AAm-co-AN)),which further encapsulated with doxorubicin(DOX)and Gd-CuS nanoparticles(Gd-CuS NPs)for chemo-photothermal treatment of HCC guided by magnetic resonance(MR)/photoacoustic(PA)dual-mode imaging.The resultant SA-PEG-p(AAm-co-AN)/DOX/Gd-CuS(SPDG)had an excellent photothermal conversion efficiency,enabling SPDG with an instantaneous release behavior of DOX under near-infrared(NIR)irradiation.This study also revealed that SPDG could actively target to HCC,which was due to that SA had a high affinity with E-selectin overexpressed at the tumor site.Moreover,benefiting from the HCC-targeted ability and NIR light-controlled on-demand delivery of DOX,SPDG showed a superior potential in MR/PA dual-mode imaging-guided chemo-photothermal treatment.Overall,our study reveals that the designed SPDG may be used as an ideal multifunctional nanoplatform for cancer theranostics. | Yan Du Di Liu Mingchen Sun Gaofeng Shu Jing Qi Yuchan You Yiting Xu Kai Fan Xiaoling Xu Feiyang Jin Jun Wang Qiying Shen Luwen Zhu Xiaoying Ying Jiansong Ji Liming Wu Daren Liu Yongzhong Du | 2022 | Nano Research2022，15，3： | 0 |
| 20 | Static Force-Based Modeling and Parameter Estimation for a Deformable Link Composed of Passive Spherical Joints With Preload Forces显示文摘To balance the contradiction between higher flexibility and heavier load bearing capacity,we present a novel deformable manipulator which is composed of active rigid joints and deformable links.The deformable link is composed of passive spherical joints with preload forces between socket-ball surfaces.To estimate the load bearing capacity of a deformable link,we present a static force-based model of spherical joint with preload force and analyze the static force propagation in the deformable link.This yields an important result that the load bearing capacity of a spherical joint only depends on its radius,preload force,and static friction coefficient.We further develop a parameter estimation method to estimate the product of preload force and static friction coefficient.The experimental results validate our model.80.4%of percentage errors on the maximum payload mass prediction are below 15%. | Gaofeng Li Dezhen Song Lei Sun Shan Xu Hongpeng Wang Jingtai Liu | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，11： | 0 |
