| 1 | Large-area straight,regular periodic surface structures produced on fused silica by the interference of two femtosecond laser beams through cylindrical lens显示文摘Inhomogeneity and low efficiency are two important factors that limit the application of laser-induced periodic surface structures(LIPSSs),especially on glass surfaces.In this study,two-beam interference(TBI)of femtosecond lasers was used to produce large-area straight LIPSSs on fused silica using cylindrical lenses.Compared with those produced us-ing a single circular or cylindrical lens,the LIPSSs produced by TBI are much straighter and more regular.Depending on the laser fluence and scanning velocity,LIPSSs with grating-like or spaced LIPSSs are produced on the fused silica sur-face.Their structural colors are blue,green,and red,and only green and red,respectively.Grating-like LIPSS patterns oriented in different directions are obtained and exhibit bright and vivid colors,indicating potential applications in surface coloring and anti-counterfeiting logos. | Long Chen Kaiqiang Cao Yanli Li Jukun Liu Shian Zhang Donghai Feng Zhenrong Sun Tianqing Jia | 2021 | Opto-Electronic Advances2021,4,12: | 7 |
| 2 | Valence state manipulation of Sm3+ ions via a phase-shaped femtosecond laser field显示文摘The ability to manipulate the valence state conversion of rare-earth ions is crucial for their applications in color displays, optoelectronic devices, laser sources, and optical memory. The conventional femtosecond laser pulse has been shown to be a well-established tool for realizing the valence state conversion of rare-earth ions, although the valence state conversion efficiency is relatively low. Here, we first propose a femtosecond laser pulse shaping technique for improving the valence state conversion efficiency of rare-earth ions. Our experimental results demonstrate that the photoreduction efficiency from Sm^(3+) to Sm^(2+) in Sm^(3+)-doped sodium aluminoborate glass using a π phase step modulation can be comparable to that using a transform-limited femtosecond laser field, while the peak laser intensity is decreased by about 63%, which is very beneficial for improving the valence state conversion efficiency under the laser-induced damage threshold of the glass sample. Furthermore, we also theoretically develop a(2 + 1)resonance-mediated three-photon absorption model to explain the modulation of the photoreduction efficiency from Sm^(3+)to Sm^(2+)under the π-shaped femtosecond laser field. | YE ZHENG YUNHUA YAO LIANZHONG DENG WENJING CHENG JIANPING LI TIANQING JIA JIANRONG QIU ZHENRONG SUN SHIAN ZHANG | 2018 | Photonics Research2018,6,2: | 4 |
| 3 | A novel intronic circular RNA,circGNG7,inhibits head and neck squamous cell carcinoma progression by blocking the phosphorylation of heat shock protein 27 at Ser78 and Ser82显示文摘Background:There is increasing evidence that circular RNAs(circRNAs)play a significant role in pathological processes including tumorigenesis.In contrast to exonic circRNAs,which are the most frequently reported circRNAs in cancer so far,the studies of intronic circRNAs have been greatly lagged behind.Here,we aimed to investigate the regulatory role of intronic circRNAs in head and neck squamous cell carcinoma(HNSCC).Methods:We conducted whole-transcriptome sequencing with four pairs of primary tumor tissues and adjacent normal tissues from HNSCC patients.Then,we characterized circGNG7 expression in HNSCC tissues and cell lines and explored its association with the prognosis of HNSCC patients.We also identified interactions between circGNG7 and functional proteins,which alter downstream signaling that regulate HNSCC progression.Results:In this study,we identified a new intronic circRNA,circGNG7,and validated its functional roles in HNSCC progression.CircGNG7 was predominately localized to the cytoplasm,and its expression was downregulated in both HNSCC tissues andCAL27,CAL33,SCC4,SCC9,HN6,and HN30 cells.Low expression of circGNG7 was significantly correlated with poor prognosis in HNSCC patients.Consistent with this finding,overexpression of circGNG7 strongly inhibited tumor cell proliferation,colony formation,in vitro migration,and in vivo tumor growth.Mechanistically,the expression of circGNG7 in HNSCC cells was regulated by the transcription factor SMAD family member 4(SMAD4).Importantly,we discovered that circGNG7 could bind to serine residues 78 and 82 of the functional heat shock protein 27(HSP27),occupying its phosphorylation sites and hindering its phosphorylation,which reduced HSP27-JNK/P38 mitogen-activated protein kinase(MAPK)oncogenic signaling.Downregulation of circGNG7 expression in HNSCC increased HSP27-JNK/P38 MAPK signaling and promoted tumor progression.Conclusions:Our results revealed that a new intronic circRNA,circGNG7,functions as a strong tumor suppressor and that circGNG7/HSP27-JNK/P38 MAPK signaling is a novel mechanism by which HNSCC progression can be controlled. | Houyu Ju Zhenrong Hu Dongliang Wei Jinyun Huang Xinyi Zhang Mengyu Rui Zhi Li Xiaomeng Zhang Jingzhou Hu Wei Guo Guoxin Ren | 2021 | Cancer Communications2021,41,11: | 4 |
| 4 | Abnormal dielectric characteristics of PMN- 32% PT single crystal under dc bias显示文摘The dielectric properties and phase transition behavior of the [001] and [111] oriented PMN-32%PT single crystal under the different dc bias (E) have been investigated as a function of temperatures. Under the application of dc bias ranging from 1.5 to 4.0 kV/cm, the dielectric spectrum of a [001] oriented single crystal showed an abnormal dielectric peak within the rhombic phase-stable temperature range. However, this peak disappeared at E>4.0 kV/cm and was not yet found in the [111] oriented single crystal. The abnormal dielectric peak was attributed to the filed-induced phase transition. | XI Zengzhe LI Zhenrong XU Zhuo ZHANG Liangying YAO Xi | 2003 | Chinese Science Bulletin2003,48,19: | 3 |
| 5 | Single-shot spectral-volumetric compressed ultrafast photography显示文摘In ultrafast optical imaging,it is critical to obtain the spatial structure,temporal evolution,and spectral composition of the object with snapshots in order to better observe and understand unrepeatable or irreversible dynamic scenes.However,so far,there are no ultrafast optical imaging techniques that can simultaneously capture the spatial–temporal–spectral five-dimensional(5D)information of dynamic scenes.To break the limitation of the existing techniques in imaging dimensions,we develop a spectral-volumetric compressed ultrafast photography(SV-CUP)technique.In our SV-CUP,the spatial resolutions in the x,y and z directions are,respectively,0.39,0.35,and 3 mm with an 8.8 mm×6.3 mm field of view,the temporal frame interval is 2 ps,and the spectral frame interval is 1.72 nm.To demonstrate the excellent performance of our SV-CUP in spatial–temporal–spectral 5D imaging,we successfully measure the spectrally resolved photoluminescent dynamics of a 3D mannequin coated with CdSe quantum dots.Our SV-CUP brings unprecedented detection capabilities to dynamic scenes,which has important application prospects in fundamental research and applied science. | Pengpeng Ding Yunhua Yao Dalong Qi Chengshuai Yang Fengyan Cao Yilin He Jiali Yao Chengzhi Jin Zhengqi Huang Li Deng Lianzhong Deng Tianqing Jia Jinyang Liang Zhenrong Sun Shian Zhang | 2021 | Advanced Photonics2021,3,4: | 3 |
| 6 | Preparation and Characterization of Flower-like Cu_2SnS_3 Nanostructures by Solvothermal Route显示文摘Flower-like Cu2SnS3 nanostructures composed of nano-flakes were successfully synthesized by solvothermal technique at 180℃for 16 h.In the preparation process,CuCI2·2H2O,SnCl2·2H2O and thiourea were used as raw materials,and ethylene glycol were used as solvent.The results showed that the obtained product was pure phase Cu2SnS3.The average diameter of Cu2SnS3 flowers and the thickness of the nano-flakes were about 1—1.5μm and 10 nm,respectively.The influence of reaction time and solvents on the morphology,size and structure of the products was investigated by powder X-ray diffraction and fieldemission scan electron microscopy(FESEM).The ultraviolet-visible absorption spectrum measurement indicated that the band gap of the sample was about 1.26 eV and could be applied to the absorbing layer of thin solar cell.The possible formation mechanism of flower-like Cu2SnS3 was also proposed and discussed. | Xiaojuan Liang Qian Cai Weidong Xiang Zhaopin Chen Jiasong Zhong Yun Wang Mingguo Shao Zhenrong Li | 2013 | Journal of Materials Science & Technology2013,29,3: | 2 |
| 7 | Design and analysis on four stage SiGe HBT low noise amplifier显示文摘Focusing on the linearity shortcoming on a bipolar low noise amplifier(LNA),a new 6 ~14GHz four stage SiGe HBT LNA is proposed.This amplifier adopts a method of gain allocation on multiple stages to avoid the limitation on linearity especially with the addition of negative gain on the third stage.To realize gain flatness,extra zero is introduced to compensate the gain roll-off formed by pole,and local shunt-shunt negative feedback is used to widen the bandwidth as well as optimize circuit' s noise.Simulated results have shown that in 6 ~14GHz,this circuit achieves noise figure(NF) less than 3dB,gain of 17.8dB(+0.2dB),input and output reflection parameters of less than- 10 dB,and the K factor is above 1.15. | 井凯 Zhuang Yiqi Li Zhenrong Lin Zhiyu | 2015 | High Technology Letters2015,21,3: | 2 |

| 11 | Growth,crystalline quality and transition variation of ternary Pb(In_(1/2)Nb_(1/2))O_(3)-Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3) ferroelectric crystals显示文摘Bulk crystals of high Curie temperature(T_(C))24Pb(In_(1/2(Nb_(1/2))O_(3)-43Pb(Mg_(1/3)Nb_(2/3))O_(3)-33PbTiO_(3)(24PIN-43PMN-33PT)with 55 mm in diameter and 130mm in length were reproducibly grown by the bottom-seeded Bridgman method.The X-ray diffraction(XRD)spectrum indicated that the as-grown crystal was a single phase with rthombohedral structure at room temperature,the domain morphology and the phase transition sequence of R→T→C were observed,the full width at half maximum(FWHM)of X-ray rocking curve of(002)face was about 0.77°,and the defect density was inferred to 2.56×10^(10)cm^(-2).The measured density of the as-grown crystals was very close to the theoretical one.Variation of the transition temperature of the as-grown crystals along the growth direction revealed that T_(C) increased linearly along the growth direction and rthombohedral to tetrahedral phase transition temperature(T_(RT))gradually decreased in the middle part of the ingot. | Linghang Wang Zhuo Xu Zhenrong Li Yuhui Wan Junjie Gao Fei Li | 2013 | Journal of Advanced Dielectrics2013,3,1: | 1 |

| 19 | Controlling multiphoton excited energy transfer from Tm^(3+) to Yb^(3+) ions by a phase-shaped femtosecond laser field显示文摘The ability to control the energy transfer in rare-earth ion-doped luminescent materials is very important for various related application areas such as color display, bio-labeling, and new light sources. Here, a phase-shaped femtosecond laser field is first proposed to control the transfer of multiphoton excited energy from Tm^(3+) to Yb^(3+) ions in co-doped glass ceramics. Tm^(3+) ions are first sensitized by femtosecond laser-induced multiphoton absorption, and then a highly efficient energy transfer occurs between the highly excited state Tm^(3+) sensitizers and the ground-state Yb^(3+) activators. The laser peak intensity and polarization dependences of the laser-induced luminescence intensities are shown to serve as proof of the multiphoton excited energy transfer pathway.The efficiency of the multiphoton excited energy transfer can be efficiently enhanced or completely suppressed by optimizing the spectral phase of the femtosecond laser with a feedback control strategy based on a genetic algorithm. A(1+2) resonance-mediated three-photon excitation model is presented to explain the experimental observations. This study provides a new way to induce and control the energy transfer in rare-earth ion-doped luminescent materials, and should have a positive contribution to the development of related applications. | YE ZHENG LIANZHONG DENG JIANPING LI TIANQING JIA JIANRONG QIU ZHENRONG SUN SHIAN ZHANG | 2019 | Photonics Research2019,7,4: | 1 |
| 20 | Practical decoy-state quantum secure direct communication显示文摘Quantum secure direct communication(QSDC) has been demonstrated in both fiber-based and free-space channels using attenuated lasers. Decoy-state QSDC by exploiting four decoy states has been proposed to address the problem of photon-numbersplitting attacks caused by the use of attenuated lasers. In this study, we present an analysis of the practical aspects of decoy-state QSDC. First, we design a two-decoy-state protocol that only requires two decoy states, thereby significantly reducing experimental complexity. Second, we successfully perform full parameter optimization for a real-life QSDC system by introducing a genetic algorithm. Our simulation results show that the two-decoy-state protocol could be the best choice for developing a practical QSDC system. Furthermore, full optimization is crucial for a high-performance QSDC system. Our work serves as a major step toward the further development of practical decoy-state QSDC systems. | Xin Liu Zijian Li Di Luo Chunfeng Huang Di Ma Minming Geng Junwei Wang Zhenrong Zhang Kejin Wei | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,12: | 1 |
