| 1 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
| 2 | Optical force-induced nonlinearity and self-guiding of light in human red blood cell suspensions显示文摘Osmotic conditions play an important role in the cell properties of human red blood cells(RBCs),which are crucial for the pathological analysis of some blood diseases such as malaria.Over the past decades,numerous efforts have mainly focused on the study of the RBC biomechanical properties that arise from the unique deformability of erythrocytes.Here,we demonstrate nonlinear optical effects from human RBCs suspended in different osmotic solutions.Specifically,we observe self-trapping and scattering-resistant nonlinear propagation of a laser beam through RBC suspensions under all three osmotic conditions,where the strength of the optical nonlinearity increases with osmotic pressure on the cells.This tunable nonlinearity is attributed to optical forces,particularly the forward-scattering and gradient forces.Interestingly,in aged blood samples(with lysed cells),a notably different nonlinear behavior is observed due to the presence of free hemoglobin.We use a theoretical model with an optical force-mediated nonlocal nonlinearity to explain the experimental observations.Our work on light self-guiding through scattering biosoft-matter may introduce new photonic tools for noninvasive biomedical imaging and medical diagnosis. | Rekha Gautam Yinxiao Xiang Josh Lamstein Yi Liang Anna Bezryadina Guo Liang Tobias Hansson Benjamin Wetzel Daryl Preece Adam White Matthew Silverman Susan Kazarian Jingjun Xu Roberto Morandotti Zhigang Chen | 2019 | Light(Science & Applications)2019，8，1： | 3 |
| 3 | Microstructure and mechanical properties of short-carbon-fiber/Ti_(3)SiC_(2) composites显示文摘Short-carbon-fibers(C_(sf))reinforced Ti_(3)SiC_(2) matrix composites(C_(sf)/Ti_(3)SiC_(2),the C_(sf) content was 0 vol%,2 vol%,5 vol%,and 10 vol%)were fabricated by spark plasma sintering(SPS)using Ti_(3)SiC_(2) powders and C_(sf) as starting materials at 1300℃.The effects of C_(sf) addition on the phase compositions,microstructures,and mechanical properties(including hardness,flexural strength(σ_(f)),and KIC)of C_(sf)/Ti_(3)SiC_(2) composites were investigated.The C_(sf),with bi-layered transition layers,i.e.,T_(IC) and SiC layers,were homogeneously distributed in the as-prepared C_(sf)/Ti_(3)SiC_(2) composites.With the increase of C_(sf) content,the K_(IC) of C_(sf)/Ti_(3)SiC_(2) composites increased,but the σ_(f) decreased,and the Vickers hardness decreased initially and then increased steadily when the C_(sf) content was higher than 2 vol%.These changed performances(hardness,σ_(f),and K_(IC))could be attributed to the introduction of C_(sf) and the formation of stronger interfacial phases. | Guangqi HE Rongxiu GUO Meishuan LI Yang YANG Linshan WANG Yuhai QIAN Jun ZUO Jingjun XU Changsheng LIU | 2020 | Journal of Advanced Ceramics2020，9，6： | 2 |
| 4 | All-optical modulation of quantum states by nonlinear metasurface显示文摘Metasurfaces have proven themselves an exotic ability to harness light at nano-scale,being important not only for classical but also for quantum optics.Dynamic manipulation of the quantum states is at the heart of quantum information processing;however,such function has been rarely realized with metasurfaces so far.Here,we report an all-optical dynamic modulation of the photonic quantum states using the nonlinear metasurface.The metasurface consists of a metallic nanostructure combined with a photoisomerizable azo layer.By tuning the plasmonic resonance through optically switching the azo molecules between their binary isomeric states,we have realized dynamic control of transmission efficiencies of orthogonally polarized photons and also the phase delay between them,thereby an entangled state was efficiently controlled.As an illustration,a quantum state distillation has been demonstrated to recover a Bell state from a non-maximally entangled one to that with fidelities higher than 98%.Our work would enrich the functions of the metasurface in the quantum world,from static to dynamic modulation,making the quantum metasurface going practical. | Di Zhang Yang Chen Shengchao Gong Wei Wu Wei Cai Mengxin Ren Xifeng Ren Shuang Zhang Guangcan Guo Jingjun Xu | 2022 | Light(Science & Applications)2022，11，3： | 1 |

| 7 | High-spatial-resolution composition analysis of micro/nanostructures with a nanoscale compositional variation显示文摘The composition of materials in a micro-/nano-devices plays a key role in determining their mechanical,physical,and chemical properties.Especially,for devices with a compositional change on nanoscale which can often be achieved by point-by-point direct writing technology using a focused ion beam(FIB),electron beam(EB),or laser beam(LB),but so far,nanoscale composition analysis of a large-area micro/nano structures with a variation composition remains a big challenge in cost,simpleness,and flexibility.Here we present a feasible route to realize large-area composition analysis with nanoscale spatial resolution by using Raman spectroscopy.We experimentally verified the capability of this method by analyzing a complex Sn-SnOx system of a microscale grayscale mask with nanoscale spatial resolution of composition.Further analyses using Auger electron spectroscopy,transmission electron microscopy,and atomic force microscopy indicated the effectiveness and practicality of our method.This work opens up a way to analyze the composition of a large-area complex system at a nanoscale spatial resolution,and the method can be extended to many other material systems. | Meng Wang Xiaofeng Wang Zhican Zhou Feng Xia Haoran Zhang Artem Shelaev Xinzheng Zhang Chuanfei Guo Jingjun Xu Qian Liu | 2023 | Nano Research2023，16，1： | 0 |
| 8 | Design of metal-organic frameworks for improving pseudo-solid-state magnesium-ion electrolytes:Open metal sites,isoreticular expansion,and framework topology显示文摘The design criteria for metal-organic frameworks(MOFs)have been established by evaluating the rela-tionship between their key characteristics and magnesium-ion conductivity based on three types of sec-ondary building blocks(Zn_(4)O(CO_(2))_(6):MOF-5 and MOF-177;Cu_(2)(CO_(2))4:MOF-199,MOF-143,MOF-14,and MOF-399;Cu_(2)O_(2)(CO_(2))2:Cu-MOF-74)to achieve pseudo-solid-state magnesium-ion conduction.We found that open-metal sites and channel layouts play a pivotal role in promoting magnesium-ion transport dy-namics at reduced activation energy,transforming MOF scaffolds into ionic-channel analogs.X-ray ab-sorption spectroscopy combined with Raman and Fourier-transform infrared spectroscopy predicted the chemical environment,solvents,and anions that occupied coordinatively unsaturated metal sites.The chemical compositions of electrolytes determined by^(1)H-NMR(nuclear magnetic resonance)and organic elemental analysis confirmed that isoreticular expansion increases the molar percentage of charge carri-ers,providing high conductivity.The current research systematically reveals the impacts of different MOF characteristics on ionic conduction performance,paving the way for the construction of a new class of fast and selective multivalent-ion pseudo-solid electrolytes. | Yun Zheng Junpo Guo De Ning Yike Huang Wen Lei Jing Li Jianding Li Götz Schuck Jingjun Shen Yan Guo Qi Zhang Hao Tian Hou Ian Huaiyu Shao | 2023 | Journal of Materials Science & Technology2023，，13： | 0 |
| 9 | Li-and Mg-based borohydrides for hydrogen storage and ionic conductor显示文摘LiBH_(4) and Mg(BH_(4))_(2) with high theoretical hydrogen mass capacity receive significant attentions for hy-drogen storage.Also,these compounds can be potentially applied as solid-state electrolytes with their high ionic conductivity.However,their applications are hindered by the poor kinetics and reversibility for hydrogen storage and low ionic conductivity at room temperature,respectively.To address these challenges,effective strategies towards engineering the hydrogen storage properties and the emerging solid-state electrolytes with improved performances have been summarized.The focuses are on the state-of-the-art developments of Li/Mg-based borohydrides with a parallel comparison of similar methods ap-plied in both hydrogen storage and solid-state electrolytes,particularly on the phase,structure,and thermal properties changes of Li/Mg-based borohydrides induced by milling,ion substitution,coordination,adding additives/catalysts,and hydrides.The similarities and differences between the strategies towards two kinds of applications are also discussed and prospected.The review will shed light on the future development of Li/Mg-based borohydrides for hydrogen storage and solid-state electrolytes. | Yike Huang Yun Zheng Jianding Li Xiaozhi Bao Junpo Guo Jingjun Shen Yan Guo Qi Zhang Jing Li Wen Lei Huaiyu Shao | 2023 | Journal of Materials Science & Technology2023，，22： | 0 |

Their work includes the experimental researches on the white light one-dimensional photovoltaic dark spatial solitons and the waveguides and directional couplers induced by them, the circular and elliptic white-light dark spatial solitons and the white-light photorefractive phase masks, two-dimensional white-light photonic lattices and the applications of the white-light dark spatial solitons in the digital image transmission field, the interaction between the two-dimensional white-light dark spatial solitons to enhance or to improve the correlated degree of the white light through the interaction between the white-light beam and coherent dark spatial solitons, the interaction between the one- or two-dimensional white-light dark spatial solitons and the two-dimensional white-light photonic lattices, respectively. We also numerically simulate the interaction between two or more partially incoherent bright spatial solitons and the white bright spatial soliton pairs in the saturated logarithmic nonlinear medium. We have observed experimentally for the first time, the modulation instability of the coherent light and white light, respectively, in self-defocusing medium and so on. | QI XinYuan LIU SiMin GUO Ru LU Yi GAO YuanMei LIU ZhaoHong HUANG ChunFu ZHANG XiaoHua ZHU Nan XU JingJun | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，5： | 0 |
| 14 | Bacterial coinfections contribute to severe COVID-19 in winter显示文摘Dear Editor,Although most cases of COVID-19 caused by SARS-CoV-2 Omicron variants are mild or asymptomatic worldwide,coinfection with SARS-CoV-2 and other respiratory pathogens may still aggravate the severity of the illness.1,2 The current literature indicates that coinfection with COVID-19 could occur in 3.70%–9.7%of patients.1,3,4 The proportion of bacterial,and other respiratory viral coinfections may range from 3.02%to 9.7%and 5.41%to 6.61%,respectively.However,these studies demonstrated that coinfections with respiratory pathogens are not common. | Hui Fan Li Zhou Jingjun Lv Shimin Yang Guozhong Chen Xinjin Liu Chunyan Han Xue Tan Shengnan Qian Zegang Wu Shan Yu Ming Guo Chengliang Zhu Yu Chen Ke Lan | 2023 | Cell Research2023，33，7： | 0 |
| 15 | A novel double polymer modified hydrophobic/hydrophilic stationary phase for liquid chromatography显示文摘In this paper,norbornene imidazolium hexafluorophosphate(NM-MIm-PF6)was modified on the surface of aminopropyl silica by ring-opening metathesis polymerization(ROMP),and then oligo(ethylene glycol)methacrylate(OEGMA)were grafted on the surface by atom transfer radical polymerization(ATRP).Some characterizations in this article confirmed that the synthesis of P(NM-MIm-PF6)-SiPOEGMA(Pl-Si-P2)is successful.The P1-Si-P2 can separate sugars,amino acids,sulfonamides in a hydrophilic interaction mode and alkyl benzene,polycyclic aromatic hydrocarbon in a reverse phase mode.The experiment also found that the column has typical characte ristics of hydrophobic/hydrophilic separation mechanism.Compared to single hydrophobic C18 column and single hydrophilic Si-NH2 column,this P1-Si-P2 shows certain advantages. | Fangbin Fan Jingjun Pan Yijing Li Licheng Wang Shuai Wang Xiaojing Liang Yong Guo | 2020 | Chinese Chemical Letters2020，31，3： | 0 |

| 17 | Transarterial chemoembolization combined with sorafenib and iodine-125 seed brachytherapy for hepatocellular carcinoma with portal vein tumor thrombus:a retrospective controlled study显示文摘To the Editor:Portal vein tumor thrombus(PVTT)is present in 10%to 40%of patients with hepatocellular carcinoma(HCC)at diagnosis and has a profound adverse effect on progno-sis.[1]Sorafenib is recommended as the first-line treatment for patients with advanced HCC,including those who have PVTT.However,its efficacy is modest.[1,2]A combination of transarterial chemoembolization(TACE)and sorafenib(TACE-S)has been reported to be associated with improved outcomes.[1,3]But unfortunately,its efficacy in controlling PVTT remained limited,with an objective response rate(ORR)of only 9.7%.[3]Previous studies have demonstrated that iodine-125(125I)seed brachytherapy targeting PVTT can lead to a significant reduction in tumor thrombus with few complications.[4,5]We hypothesized that TACE-S combined with 125I seed brachytherapy(TACE-S-I)could improve the control of PVTT and confer a greater survival benefit.Therefore,we conducted this study to evaluate the efficacy and safety of TACE-S-I compared with TACE-S in HCC patients with PVTT.This study was approved by our institutional review board(No.2020-hg-ks-03). | Jingjun Huang Mingyue Cai Wensou Huang Yongjian Guo Jingwen Zhou Licong Liang Liteng Lin Zhimei Zhou Hui Lian Mingji He Kangshun Zhu | 2022 | Chinese Medical Journal2022，，1： | 0 |
