| 1 | Multichannel vectorial holographic display and encryption显示文摘Since its invention,holography has emerged as a powerful tool to fully reconstruct the wavefronts of light including all the fundamental properties(amplitude,phase,polarization,wave vector,and frequency).For exploring the full capability for information storage/display and enhancing the encryption security of metasurface holograms,smart multiplexing techniques together with suitable metasurface designs are highly demanded.Here,we integrate multiple polarization manipulation channels for various spatial phase profiles into a single birefringent vectorial hologram by completely avoiding unwanted cross-talk.Multiple independent target phase profiles with quantified phase relations that can process significantly different information in different polarization states are realized within a single metasurface.For our metasurface holograms,we demonstrate high fidelity,large efficiency,broadband operation,and a total of twelve polarization channels.Such multichannel polarization multiplexing can be used for dynamic vectorial holographic display and can provide triple protection for optical security.The concept is appealing for applications of arbitrary spin to angular momentum conversion and various phase modulation/beam shaping elements. | Ruizhe Zhao Basudeb Sain Qunshuo Wei Chengchun Tang Xiaowei Li Thomas Weiss Lingling Huang Yongtian Wang Thomas Zentgraf | 2018 | Light(Science & Applications)2018，7，1： | 15 |
| 2 | Controllable optical activity with non-chiral plasmonic metasurfaces显示文摘Optical activity is the rotation of the plane of linearly polarized light along the propagation direction as the light travels through optically active materials.In existing methods,the strength of the optical activity is determined by the chirality of the materials,which is difficult to control quantitatively.Here we numerically and experimentally investigated an alternative approach to realize and control the optical activity with non-chiral plasmonic metasurfaces.Through judicious design of the structural units of the metasurfaces,the right and left circular polarization components of the linearly polarized light have different phase retardations after transmitting through the metasurfaces,leading to large optical activity.Moreover,the strength of the optical activity can be easily and accurately tuned by directly adjusting the phase difference.The proposed approach based on non-chiral plasmonic metasurfaces exhibits large optical activity with a high controllable degree of freedom,which may provide more possibilities for applications in photonics. | Ping Yu Jianxiong Li Chengchun Tang Hua Cheng Zhaocheng Liu Zhancheng Li Zhe Liu Changzhi Gu Junjie Li Shuqi Chen Jianguo Tian | 2016 | Light(Science & Applications)2016，5，1： | 8 |
| 3 | Magnetostriction of Pseudobinary Compounds Pr_(0.15)Tb_xDy_(0.85-x)Fe_2(x=0 to 0.85)显示文摘The compound ingots of Pr0.15TbxDy0.85-xFe2 (x=0 to 0.85) were prepared by arc melting in a water Cu boat using arc furnace under a purified Ar atmosphere. Appropriate annealing (850℃, 100 h) can obtain single Laves phase compound. The magnetostriction for these systems will rise obviously when partially substituted Tb or Dy by Pr. | Yangxian LI and Jingping QU (Hebei University of Technology, Tianjin 300130, China) Chengchun TANG, Guangheng WU and Wenshan ZHAN (State Key Laboratory for Magnetism, Institute of Physics, CAS, BeiJing 100080, China) | 2000 | Journal of Materials Science & Technology2000，16，6： | 2 |

| 11 | Direct stamping multifunctional tactile sensor for pressure and temperature sensing显示文摘Flexible and wearable sensors have broad application prospects in health monitoring and artificial intelligence.Many different single-functional sensing devices have been developed in recent years,such as pressure sensors and temperature sensors.However,it is still a great challenge to design and fabricate tactile sensors with multiple sensing functions.Herein,we propose a simple direct stamping method for the fabrication of multifunctional tactile sensors.It can detect pressure and temperature stimuli signals simultaneously.This pressure/temperature sensor possesses high sensitivity(0.67 kPa^(-1)),large linear range(0.75-5 kPa),and fast response speed(15.6 ms)in pressure sensing.It also has a high temperature sensitivity(1.41%/℃)and great linearity(0.99)for temperature sensing in the range of-30 to 30℃.All these excellent performances indicate that this pressure/temperature sensor has great potential in applications for artificial intelligence and health monitoring. | Binghao Liang Bingfang Huang Junkai He Rongliang Yang Chengchun Zhao Bo-Ru Yang Anyuan Cao Zikang Tang Xuchun Gui | 2022 | Nano Research2022，15，4： | 1 |

| 15 | An Adaptive DDoS Detection and Classification Method in Blockchain Using an Integrated Multi-Models显示文摘With the rising adoption of blockchain technology due to its decentralized,secure,and transparent features,ensuring its resilience against network threats,especially Distributed Denial of Service(DDoS)attacks,is crucial.This research addresses the vulnerability of blockchain systems to DDoS assaults,which undermine their core decentralized characteristics,posing threats to their security and reliability.We have devised a novel adaptive integration technique for the detection and identification of varied DDoS attacks.To ensure the robustness and validity of our approach,a dataset amalgamating multiple DDoS attacks was derived from the CIC-DDoS2019 dataset.Using this,our methodology was applied to detect DDoS threats and further classify them into seven unique attack subcategories.To cope with the broad spectrum of DDoS attack variations,a holistic framework has been pro-posed that seamlessly integrates five machine learning models:Gate Recurrent Unit(GRU),Convolutional Neural Networks(CNN),Long-Short Term Memory(LSTM),Deep Neural Networks(DNN),and Support Vector Machine(SVM).The innovative aspect of our framework is the introduction of a dynamic weight adjustment mechanism,enhancing the system’s adaptability.Experimental results substantiate the superiority of our ensemble method in comparison to singular models across various evaluation metrics.The framework displayed remarkable accuracy,with rates reaching 99.71%for detection and 87.62%for classification tasks.By developing a comprehensive and adaptive methodology,this study paves the way for strengthening the defense mechanisms of blockchain systems against DDoS attacks.The ensemble approach,combined with the dynamic weight adjustment,offers promise in ensuring blockchain’s enduring security and trustworthiness. | Xiulai Li Jieren Cheng Chengchun Ruan Bin Zhang Xiangyan Tang Mengzhe Sun | 2023 | Computers, Materials & Continua2023，77，12： | 0 |
| 16 | Synthesis and characterization of nanocrystalline NaTaO_3显示文摘Tantalum pentoxide reacts actively with concentrated NaOH solution under hydrothermal conditions at 180 ℃. In the reaction between NaOH solution and Ta2O5, the structure and composition of the tantalates depend on the reaction time, and the structure evolution results in a remarkable change in light absorption. Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet-visible (UV-Vis) diffused reflection spectrum were used to characterize various properties of the obtained solid products. At 180 ℃, the reaction proceeds rapidly. With the increase of time, the reflection peaks of unreacted Ta2O5 in the XRD patterns becomes weaker and weaker. Pure NaTaO3 is obtained after 60 min, which is well crystallized with a uniform cubic morphology. | CHEN Jingfang HU Long ZHAO Jianling TANG Chengchun LI Yangxian | 2006 | Rare Metals2006，25，z2： | 0 |
| 17 | Synthesis and Magnetostriction of (Ce_xTb_(1-x))_(0.5)Pr_(0.5)Fe_2 Compounds显示文摘The structural and magnetostrictive properties of (CexTb1-x)0.5Pr0.5Fe2 were investigated. Ceconcentration must exceed x=0.6 in order to obtain the pure Laves phase. The magnetostriction and anisotropy constant increase with the Tb-content in this system. The anisotropy value of PrFe2 is lower than that of isostructural DyFe2. From the X-ray step-scanned data we found that λ111 of PrFe2 is 1310x10-6. A large increase of magnetostriction can be observed under a small prestress of 6 MPa for Ce0.5Pr0.5Fe2. | Yangxian LI, Guizhi XU and Jingping QU (School of Materials Science and Engineering, Hebei University of Technology, Tianjin 300130, China) Chengchun TANG, Guangheng WU and Wenshan ZHAN (State Key Laboratory for Magnetism, Institute of Physics, Chinese Academy of Sciences, Beijing 100080, China) | 2000 | Journal of Materials Science & Technology2000，16，2： | 0 |
