| 1 | Large aperture N31 neodymium phosphate laser glass for use in a high power laser facility显示文摘Large aperture Nd:phosphate laser glass is a key optical element for an inertial confinement fusion(ICF) facility. N31,one type of neodymium doped phosphate glasses, was developed for high peak power laser facility applications in China. The composition and main properties of N31 glass are given, together with those of LHG-8, LG-770, and KGSS-0180 Nd:phosphate laser glasses, from Hoya and Schott, and from Russia. The technologies of pot melting, continuous melting, and edge cladding of large size N31 phosphate laser glass are briefly described. The small signal gain profiles of N31 glass slabs from both pot melting and continuous melting at various values of the pumping energy of the xenon lamp are presented. N31 glass is characterized by a stimulated emission cross section of 3.8 × 10-20cm2 at 1053 nm,an absorption coefficient of 0.10–0.15% cm-1at laser wavelength, small residual stress around the interface between the cladding glass and the laser glass, optical homogeneity of ~2 × 10-6in a 400 mm aperture, and laser damage threshold larger than 42 J/cm2 for a 3 ns pulse width at 1064 nm wavelength. | Lili Hu Shubin Chen Jingping Tang Biao Wang Tao Meng Wei Chen Lei Wen Junjiang Hu Shunguang Li Yongchun Xu Yasi Jiang Junzhou Zhang Zhonghong Jiang | 2014 | High Power Laser Science and Engineering2014，2，1： | 8 |
| 2 | Stepwise-Nanocavity-Assisted Transmissive Color Filter Array Microprints显示文摘Visible-light color flters using patterned nanostructures have attracted much interest due to their various advantages such as compactness,enhanced stability,and environmental friendliness compared with traditional pigment or dye-based optical flters.While most existing studies are based on planar nanostructures with lateral variation in size,shape,and arrangement,the vertical dimension of structures is a long-ignored degree of freedom for the structural colors.Herein,we demonstrate a synthetic platform for transmissive color flter array by coordinated manipulations between height-varying nanocavities and their lateral flling fractions.Te thickness variation of those nanocavities has been fully deployed as an alternative degree of freedom,yielding vivid colors with wide gamut and excellent saturation.Experimental results show that the color-rendering capability of the pixelated nanocavities can be still retained as pixels are miniaturized to 500 nm.Crosstalk between closely spaced pixels of a Bayer color flter arrangement was calculated,showing minimal crosstalk for 1μm2 square subpixels.Our work provides an approach to designing and fabricating ultracompact color flter arrays for various potential applications including stained-glass microprints,microspectrometers,and high-resolution image sensing systems. | Yasi Wang Mengjie Zheng Qifeng Ruan Yanming Zhou Yiqin Chen Peng Dai Zhengmei Yang Zihao Lin Yuxiang Long Ying Li Na Liu Cheng-Wei Qiu Joel K.W.Yang Huigao Duan | 2018 | Research2018，，1： | 8 |
| 3 | 3D-Integrated metasurfaces for full-colour holography显示文摘Metasurfaces enable the design of optical elements by engineering the wavefront of light at the subwavelength scale.Due to their ultrathin and compact characteristics,metasurfaces possess great potential to integrate multiple functions in optoelectronic systems for optical device miniaturisation.However,current research based on multiplexing in the 2D plane has not fully utilised the capabilities of metasurfaces for multi-tasking applications.Here,we demonstrate a 3D-integrated metasurface device by stacking a hologram metasurface on a monolithic Fabry–Pérot cavity-based colour filter microarray to simultaneously achieve low-crosstalk,polarisation-independent,high-efficiency,full-colour holography,and microprint.The dual functions of the device outline a novel scheme for data recording,security encryption,colour displays,and information processing.Our 3D integration concept can be extended to achieve multi-tasking flat optical systems by including a variety of functional metasurface layers,such as polarizers,metalenses,and others. | Yueqiang Hu Xuhao Luo Yiqin Chen Qing Liu Xin Li Yasi Wang Na Liu Huigao Duan | 2019 | Light(Science & Applications)2019，8，1： | 6 |
| 4 | A stable and efficient La-doped MIL-53(Al)/ZnO photocatalyst for sulfamethazine degradation显示文摘Photocatalytic technology can solve various environmental pollution problems,especially antibiotic pollution.A novel La-doped MIL-53(Al)/ZnO composite material was successfully synthesized by a combination of hydrothermal method and calcination,showing high photocatalytic degradation percent of sulfamethazine(SMT).The 2 mol%La MIL-53(Al)/ZnO photocatalyst shows the highest degradation efficiency toward SMT(92%)within 120 min,which is 4.1 times higher than pure ZnO(increased from 18%to 92%).In addition,the degradation analysis of SMT by high performance liquid chromatography proves that the products are CO_(2) and H_(2)O.The improved photocatalytic activity is mostly caused by the following factors.(1)Doping La ions can decrease the band gap of ZnO,enhance light response,and effectively enhance the separation rate of photo-generated holes and electrons.(2)MIL-53(Al)can adsorb SMT and promote the separation of electron.This work shows that the synthesized La-doped MIL-53(Al)/ZnO photocatalyst is expected to be used as a green and effective method for treatment of environment water pollution. | Qiuming Wei Wei Li Chun Jin Yasi Chen Linlin Hou Zhiliang Wu Zhongliang Pan Qinyu He Yinzhen Wang Dingyuan Tang | 2022 | Journal of Rare Earths2022，40，4： | 2 |
| 5 | The gene expression level and prognosis analysis of membrane protein AP2M1 based on the protein spectrum of exosomes in hepatocellular carcinoma cells显示文摘Objective:Adopting mass spectrometry to analyze the protein spectrum of the exosomes in human hepatocellular carcinoma cells and screening the target membrane protein in order to analyze the relationship between its gene expression level and prognosis.Methods:The exosomes of hepatocellular carcinoma cells HepG2 and 7721 were isolated by ultracentrifugation,and the extracted exosomes were verified by transmission electron microscope, western blotting,and nanosight.The relative quantitative proteomics analysis was used to analyze the protein spectrum of HepG2 and 7721 cells in exosomes.The bioinformatics was used to collect the signal pathway,and the target protein AP2M1 was verified by qRTPCR.Gene Expression Profiling Interactive Analysis(GEPIA),OncoLnc,and The Cancer Genome Atlas(TCGA)database were used to analyze the expression level of AP2M1 and the survival rate of patients with liver cancer.Results:The extracellular exosomes of HepG2 and 7721 cells were isolated by ultracentrifugation.High-purity exosomes were obtained and verified by transmission electron microscopy,western blotting,and nanosight.There were 836 proteins co-expressed by the exosomes of HepG2 and 7721.By the analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway,a total of 34 pathways that were related to liver cancer were collected,and the target membrane protein AP2M1 was screened.AP2M1 highly expressed in HepG2 cells,HepG2 and Huh7 cells' exosomes were detected by qRT-PCR(P<0.05).The data of GEPIA showed that comparing to the adjacent tissues,gene AP2M1 was highly expressed in hepatocarcinoma tissues.Kaplan-Meier survival curve analysis was performed by OncoLnc.It was found that the survival rate of patients with liver cancer and high expression of AP2M1 was significantly lower than patients with liver cancer and low expression of AP2M1(P<0.01).Conclusion:The high expression of membrane protein AP2M1 in the exosomes of hepatoma cells and the high expression of its gene in liver cancer tissues predicted the low survival rate. | Lifang Liang Chunmeng Wei Yasi Li Fengjie Wan Xuejing Huang Min He | 2018 | 广西医科大学学报2018，35，11： | 1 |
