| 1 | Effects of r-HuEPO on the biophysical characteristics of erythrocyte membrane in patients with anemia of chronic renal failure显示文摘Using electron spin resonance (ESR) spin labeling technique, we have studied the conformation of sulfhydryl groups(-SH) binding sites in membrane proteins and membrane fluidity of red blood cells (RBCs) from two groups of patients with anemia of chronic renal failure (ACRF). One of the groups is composed of patients who were untreated with recombinant human erythropoietin(r-HuEPO), and the other is composed of patients who were treated with r-HuEPO. The results indicated: 1) the conformation of SH group binding site in RBC membrane proteins from former group was different from those of health people. 2)the fluidity in the region near the surface of RBC membrane from former group was lower than those of healthy people. 3) However, the above biophysical properties of RBC membrane from later group were normal. We concluded that RBC membrane in patients with ACRF was abnormal, and the treatment of r-HuEPO may promote the production of normal RBCs, thus ameliorate the biophysical properties of RBCs from the patients with ACRF. | SHI HONGLIAN FAJUN YANG BAOLU ZHAO WENJUAN XIN(Institute of Biophysics, Academia Sinica, Beijing, China.) | 1994 | Cell Research1994，4，1： | 8 |
| 2 | Cylindrical vector beam-excited frequency-tunable second harmonic generation in a plasmonic octamer显示文摘We report a method to tune the second harmonic generation(SHG) frequency of a metallic octamer by employing cylindrical vector beams as the excitation. Our method exploits the ability to spatially match the polarization state of excitations with the fundamental target plasmonic modes, enabling flexible control of the SHG resonant frequency.It is found that SHG of the octamer is enhanced over a broad band(400 nm) by changing the excitation from the linearly polarized Gaussian beam to radially and azimuthally polarized beams. More strikingly, when subjected to an azimuthally polarized beam, the SHG intensity of the octamer becomes 30 times stronger than that for the linearly polarized beam even in the presence of Fano resonance. | FAJUN XIAO WUYUN SHANG WEIREN ZHU LEI HAN MALIN PREMARATNE TING MEI JIANLIN ZHAO | 2018 | Photonics Research2018，6，3： | 6 |
| 3 | A rapid and accurate direct measurement method of underground coal seam gas content based on dynamic diffusion theory显示文摘Coal seam gas content is frequently measured in quantity during underground coal mining operation and coalbed methane(CBM)exploration as a significant basic parameter.Due to the calculation error of lost gas and residual gas in the direct method,the efficiency and accuracy of the current methods are not inadequate to the large area multi-point measurement of coal seam gas content.This paper firstly deduces a simplified theoretical dynamic model for calculating lost gas based on gas dynamic diffusion theory.Secondly,the effects of various factors on gas dynamic diffusion from coal particle are experimentally studied.And sampling procedure of representative coal particle is improved.Thirdly,a new estimation method of residual gas content based on excess adsorption and competitive adsorption theory is proposed.The results showed that the maximum error of calculating the losing gas content by using the new simplified model is only 4%.Considering the influence of particle size on gas diffusion law,the particle size of the collected coal sample is below 0.25 mm,which improves the measurement speed and reflects the safety representativeness of the sample.The determination time of gas content reduced from 36 to 3 h/piece.Moreover,the absolute error is 0.15–0.50 m^3/t,and the relative error is within 5%.A new engineering method for determining the coal seam gas content is developed according to the above research. | Yanwei Liu Yang Du Zhiqiang Li Fajun Zhao Weiqin Zuo Jianping Wei Hani Mitri | 2020 | International Journal of Mining Science and Technology2020，30，6： | 6 |
| 4 | Magnetic plasmon resonances in nanostructured topological insulators for strongly enhanced light-MoS_(2) interactions显示文摘Magnetic resonances not only play crucial roles in artificial magnetic materials but also offer a promising way for light control and interaction with matter.Recently,magnetic resonance effects have attracted special attention in plasmonic systems for overcoming magnetic response saturation at high frequencies and realizing high-performance optical functionalities.As novel states of matter,topological insulators(TIs)present topologically protected conducting surfaces and insulating bulks in a broad optical range,providing new building blocks for plasmonics.However,until now,high-frequency(e.g.visible range)magnetic resonances and related applications have not been demonstrated in TI systems.Herein,we report for the first time,to our knowledge,a kind of visible range magnetic plasmon resonances(MPRs)in TI structures composed of nanofabricated Sb_(2)Te_(3) nanogrooves.The experimental results show that the MPR response can be tailored by adjusting the nanogroove height,width,and pitch,which agrees well with the simulations and theoretical calculations.Moreover,we innovatively integrated monolayer MoS_(2) onto a TI nanostructure and observed strongly reinforced light-MoS_(2) interactions induced by a significant MPR-induced electric field enhancement,remarkable compared with TI-based electric plasmon resonances(EPRs).The MoS_(2) photoluminescence can be flexibly tuned by controlling the incident light polarization.These results enrich TI optical physics and applications in highly efficient optical functionalities as well as artificial magnetic materials at high frequencies. | Hua Lu Zengji Yue Yangwu Li Yinan Zhang Mingwen Zhang Wei Zeng Xuetao Gan Dong Mao Fajun Xiao Ting Mei Weiyao Zhao Xiaolin Wang Min Gu Jianlin Zhao | 2020 | Light(Science & Applications)2020，9，1： | 3 |
| 5 | Selective excitation of a three-dimensionally oriented single plasmonic dipole显示文摘We experimentally demonstrate a scheme to deterministically excite a three-dimensionally oriented electric dipole in a single Au nanosphere by using a tightly focused radially polarized beam whose focal field possesses polarization states along three-dimensional(3D) orientations owing to the spatial overlap between longitudinal and radial electric field components. Experiment observations indicate that the orientation of an excited dipole moment gradually changes from out-of-plane to in-plane when the nanosphere is moved away from the beam center, which is reconfirmed by full-wave simulations. Moreover, rigorous calculation based on Mie theory reveals that a reduced effective ambient permittivity accompanies the rotation of the dipole moment, leading to a blue-shifted and narrowed resonance peak. We envision that our results could find applications in detecting the 3D orientation of isolated molecules and benefit the fine manipulation of light–matter interactions at the single-molecule level. | FAJUN XIAO GUANGLIN WANG XUETAO GAN WUYUN SHANG SHIYIN CAO WEIREN ZHU TING MEI MALIN PREMARATNE JIANLIN ZHAO | 2019 | Photonics Research2019，7，6： | 3 |

| 8 | Influence of parameters on light propagation dynamics in optically induced planar waveguide arrays显示文摘The diffraction and refraction of light beam in optical periodic structures can be determined by the photonic band-gap structures of spatial frequency.In this paper,by employing the equation governing the nonlinear light propagations in photorefractive crystals,we study the photonic band-gap structures, Bloch modes,and light transmission properties of optically induced planar waveguide arrays.The relationship between the photonic band-gap structures and the light diffraction characteristics is discussed in detail.Then the influence of the parameters of planar waveguide arrays on the band-gaps structures,Bloch modes,and linear light transmissions is analyzed.It is revealed that the linear light transmission properties of waveguide arrays are tightly related to the diffraction relationships determined by band-gap structures.And the Bloch modes corresponding to different transmission bands can be excited by different excitation schemes.Both the increases of the intensity and the period of the array writing beam will lead to the broadening of the forbidden gaps and the concentration of the energy of the Bloch modes to the high-index regions.Furthermore,the broadening of the forbidden gaps will lead to separation and transition between the Bloch modes of neighboring bands around the Bragg angle.Additionally,with the increase of the intensity of the array writing beams,the influences from light intensity will tend to be steady due to the saturation of the photorefractive effect. | LIU Sheng ZHANG Peng XIAO FaJun YANG DeXing ZHAO JianLin | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，5： | 0 |
| 9 | Augmenting photoluminescence of monolayer MoS_(2) using high order modes in a metal dimer-on-film nanocavity显示文摘Plasmonic particle-on-film nanocavities,supporting gap modes with ultra-small volume,provide a great solution to boost light–matter interactions at the nanoscale.In this work,we report on the photoluminescence(PL)enhancement of monolayer MoS_(2) using high order modes of an Au nanosphere dimer-on-film nanocavity(DoFN).The high order plasmon modes,consisting of two bonding quadrupoles in the dimer and their images in the Au film,are revealed by combining the polarization-resolved scattering spectra with the numerical simulations.Further integrating the monolayer MoS_(2) into the DoFN,these high order modes are used to enhance PL intensity through simultaneously boosting the absorption and emission processes,producing a 1350-fold enhancement factor.It opens an avenue to enhance the light–matter interaction with high order plasmon modes and may find applications in future optoelectronics and nanophotonics devices. | Shiyin Cao Liping Hou Qifa Wang Chenyang Li Weixing Yu Xuetao Gan Kaihui Liu Malin Premaratne Fajun Xiao Jianlin Zhao | 2021 | Photonics Research2021，9，4： | 0 |
