| 1 | One-to-many optical information encryption transmission method based on temporal ghost imaging and code division multiple access显示文摘A method is presented for one-to-many information encryption transmission by using temporal ghost imaging and code division multiple access.In the encryption transmission process,code division multiple access technologies combine multiple information sources,and the chip sequence corresponding to each set of information is used as the first key.The transmission end loads the transmission information onto a series of temporal random patterns of temporal ghost imaging and transmits it to the receivers.A series of temporal random patterns is the second key.During the decryption,each receiver can get the same encrypted information and use the second key to obtain the transmitted information.Finally,each receiver uses the unique chip sequence to get corresponding information.This encryption transmission method realizes one-to-many information encryption transmission at the same time over the same channel.Double encryption ensures the security of information.Simulation and experiment results verify the effectiveness and security of the method.The method has strong antinoise ability and can effectively resist various attack modes.At the same time,this method solves the problem that the use of code division multiple access enlarges the signal bandwidth,and ensures that no cross talk occurs between various sources of information. | YI KANG LEIHONG ZHANG HUALONG YE MANTONG ZHAO SAIMA KANWAL CHUNYAN BAI DAWEI ZHANG | 2019 | Photonics Research2019，7，12： | 4 |
| 2 | Optimum Position of Electromagnetic Brake on Slab Caster显示文摘Three-dimensional mathematical models were developed for studying the molten steel flow and the trajectories of inclusions and bubbles in continuous casting mold with electromagnetic brake. The results show that the effect of the electromagnetic brake on the molten steel flow and the movement of inclusions and bubbles depends on the position of electromagnetic brake. While EMBR Ruler is installed at the exit of the submerged entry nozzle, the velocity of the main jet of molten steel from the nozzle can be decreased effectively, the velocity of the molten steel streams near the free surface and the narrow face is reduced obviously; Meantime more inclusions and bubbles could float up to the slag layer. | LEIHong ZHUMiao-yong HEJi-cheng | 2003 | Journal of Iron and Steel Research(International)2003，10，2： | 2 |
| 3 | Polarization-independent highly efficient generation of Airy optical beams with dielectric metasurfaces显示文摘Airy optical beams have emerged to hold enormous theoretical and experimental research interest due to their outstanding characteristics.Conventional approaches suffer from bulky and costly systems,as well as poor phase discretization.The newly developed metasurface-based Airy beam generators have constraints of polarization dependence or limited generation efficiency.Here,we experimentally demonstrate a polarization-independent silicon dielectric metasurface for generation of high-efficiency Airy optical beams.In our implementation,rather than synchronous manipulation of the amplitude and phase by plasmonic or Huygens’metasurfaces,we employ and impose a 3/2 phase-only manipulation to the dielectric metasurface,consisting of an array of silicon nanopillars with an optimized transmission efficiency as high as 97%.The resultant Airy optical beams possess extraordinarily large deflection angles and relatively narrow beam widths.Our validated scheme will open up a fascinating doorway to broaden the application scenarios of Airy optical beams on ultracompact photonic platforms. | Binbin Yu Jing Wen Lei Chen Leihong Zhang Yulong Fan Bo Dai Saima Kanwal Dangyuan Lei Dawei Zhang | 2020 | Photonics Research2020，8，7： | 2 |

| 6 | Maximization of the sum of the trace ratio on the Stiefel manifold, II: Computation显示文摘Abstract The necessary condition established in Part I of this paper for the global maximizers of the maximization problem max V tr(VTAV)/tr(VTBV)+tr(VTCV)over the Stiefel manifold{V∈Rm×l |VTV=Il}(l | ZHANG LeiHong LI RenCang | 2015 | Science China Mathematics2015，58，7： | 1 |
| 7 | Maximization of the sum of the trace ratio on the Stiefel manifold, I: Theory显示文摘We are concerned with the maximization of tr(VTAV)/tr(VT BV)+ tr(VT CV)over the Stiefel manifold {V ∈ Rm×| V T V = It}(t < m), where B is a given symmetric and positive definite matrix, A and C are symmetric matrices, and tr() is the trace of a square matrix. This is a subspace version of the maximization problem studied in Zhang(2013), which arises from real-world applications in, for example,the downlink of a multi-user MIMO system and the sparse Fisher discriminant analysis in pattern recognition.We establish necessary conditions for both the local and global maximizers and connect the problem with a nonlinear extreme eigenvalue problem. The necessary condition for the global maximizers offers deep insights into the problem, on the one hand, and, on the other hand, naturally leads to a self-consistent-field(SCF)iteration to be presented and analyzed in detail in Part II of this paper. | ZHANG LeiHong LI RenCang | 2014 | Science China Mathematics2014，57，12： | 1 |

| 9 | Application of Ag/AgBr/GdVO_4 composite photocatalyst in wastewater treatment显示文摘Ag/AgBr/GdVO_4 composite photocatalysts were designed and synthesized in this paper.The physical and chemical structures, as well as optical properties of the synthesized composite were investigated via XRD, XPS, TEM, and UV–vis. It is found that the composite showed a ternary heterojunction structure of Ag, Ag Br and GdVO_4. Meanwhile, it has a high intensity of light current, indicating its high separation efficiency of electron and hole.Photocatalytic oxidation of rhodamine B(RhB) under visible light irradiation was performed to investigate the activity of the Ag/Ag Br/GdVO_4 composite. Result indicates that it shows excellent photocatalytic activity. Under visible light irradiation for 12 min, about 80% of Rh B(30 μmol/L) was degraded. The degradation rate is estimated to be 0.253 min1, which is three times higher than that of pure AgBr. The high photoactivity can be ascribed to the synergetic effect of Ag Br, GdVO_4, and Ag nanoparticle in separation of electron–hole pairs. | Xin Zhang Chenghao Wang Chengxi Yu Botao Teng Yiming He Leihong Zhao Maohong Fan | 2018 | Journal of Environmental Sciences2018，30，1： | 1 |

| 19 | High piezo/photocatalytic efficiency of Ag/Bi_(5)O_(7)I nanocomposite using mechanical and solar energy for N2 fixation and methyl orange degradation显示文摘In this work,Ag/Bi_(5)O_(7)I nanocomposite was prepared and firstly applied in piezo/photocatalytic reduction of N2 to NH3 and methyl orange(MO)degradation.Bi_(5)O_(7)I was synthesized via a hydrothermal-calcination method and shows nanorods morphology.Ag nanoparticles(NPs)were photo deposited on the Bi_(5)O_(7)I nanorods as electron trappers to improve the spatial separation of charge carriers,which was confirmed via XPS,TEM,and electronic chemical analyses.The catalytic test indicates that Bi_(5)O_(7)I presents the piezoelectric-like behavior,while the loading of Ag NPs can strengthen the character.Under ultrasonic vibration,the optimal Ag/Bi_(5)O_(7)I presents high efficiency in MO degradation.The degradation rate is determined to be 0.033 min1,which is 4.7 folds faster than that of Bi_(5)O_(7)I.The Ag/Bi_(5)O_(7)I also presents a high performance in piezocatalytic N2 fixation.The piezocatalytic NH3 generation rate reaches 65.4 μmol L^(-1)g^(-1)h^(-1)with water as a hole scavenger.The addition of methanol can hasten the piezoelectric catalytic reaction.Interestingly,when ultrasonic vibration and light irradiation simultaneously act on the Ag/Bi_(5)O_(7)I catalyst,higher performance in NH3 generation and MO degradation is observed.However,due to the weak adhesion of Ag NPs,some Ag NPs would fall off from the Bi_(5)O_(7)I surface under long-term ultrasonic vibration,which would greatly reduce the piezoelectric catalytic performance.This result indicates that a strong binding force is required when preparing the piezoelectric composite catalyst.The current work provides new insights for the development of highly efficient catalysts that can use multiple energies. | Lu Chen Wenqian Zhang Junfeng Wang Xiaojing Li Yi Li Xin Hu Leihong Zhao Ying Wu Yiming He | 2023 | Green Energy & Environment2023，8，1： | 1 |
| 20 | Study on the key technology of spectral reflectivity reconstruction based on sparse prior by a single-pixel detector显示文摘By studying the traditional spectral reflectance reconstruction method, spectral reflectance and the relative spectral power distribution of a lighting source are sparsely decomposed, and the orthogonal property of the principal component orthogonal basis is used to eliminate basis; then spectral reflectance data are obtained by solving a sparse coefficient. After theoretical analysis, the spectral reflectance reconstruction based on sparse prior knowledge of the principal component orthogonal basis by a single-pixel detector is carried out by software simulation and experiment. It can reduce the complexity and cost of the system, and has certain significance for the improvement of multispectral image acquisition technology. | Leihong Zhang Dong Liang Bei Li Yi Kang Zilan Pan Dawei Zhang Xiuhua Ma | 2016 | Photonics Research2016，4，3： | 1 |
