| 1 | Three-dimensional chiral microstructures fabricated by structured optical vortices in isotropic material显示文摘Optical vortices,a type of structured beam with helical phase wavefronts and‘doughnut’-shaped intensity distributions,have been used to fabricate chiral structures in metals and spiral patterns in anisotropic polarization-dependent azobenzene polymers.However,in isotropic polymers,the fabricated microstructures are typically confined to non-chiral cylindrical geometry due to the two-dimensional‘doughnut’-shaped intensity profile of the optical vortices.Here we develop a powerful strategy to realize chiral microstructures in isotropic material by coaxial interference of a vortex beam and a plane wave,which produces threedimensional(3D)spiral optical fields.These coaxial interference beams are generated by designing contrivable holograms consisting of an azimuthal phase and an equiphase loaded on a liquid-crystal spatial light modulator.In isotropic polymers,3D chiral microstructures are achieved under illumination using coaxial interference femtosecond laser beams with their chirality controlled by the topological charge.Our further investigation reveals that the spiral lobes and chirality are caused by interfering patterns and helical phase wavefronts,respectively.This technique is simple,stable and easy to perform,and it offers broad applications in optical tweezers,optical communications and fast metamaterial fabrication. | Jincheng Ni Chaowei Wang Chenchu Zhang Yanlei Hu Liang Yang Zhaoxin Lao Bing Xu Jiawen Li Dong Wu Jiaru Chu | 2017 | Light(Science & Applications)2017，6，1： | 28 |
| 2 | Bioinspired micro/nanostructured surfaces prepared by femtosecond laser direct writing for multi-functional applications显示文摘manufacturing of biomimetic micro/nanostructures due to its specific advantages including high precision,simplicity,and compatibility for diverse materials in comparison with other methods(e.g.ion etching,sol-gel process,chemical vapor deposition,template method,and self-assembly).These biomimetic micro/nanostructured surfaces are of significant interest for academic and industrial research due to their wide range of potential applications,including self-cleaning surfaces,oil-water separation,and fog collection.This review presents the inherent relationship between natural organisms,fabrication methods,micro/nanostructures and their potential applications.Thereafter,we throw a list of current fabrication strategies so as to highlight the advantages of FLDW in manufacturing bioinspired microstructured surfaces.Subsequently,we summarize a variety of typical bioinspired designs(e.g.lotus leaf,pitcher plant,rice leaf,butterfly wings,etc)for diverse multifunctional micro/nanostructures through extreme femtosecond laser processing technology.Based on the principle of interfacial chemistry and geometrical optics,we discuss the potential applications of these functional micro/nanostructures and assess the underlying challenges and opportunities in the extreme fabrication of bioinspired micro/nanostructures by FLDW.This review concludes with a follow up and an outlook of femtosecond laser processing in biomimetic domains. | Yiyuan Zhang Yunlong Jiao Chuanzong Li Chao Chen Jiawen Li Yanlei Hu Dong Wu Jiaru Chu | 2020 | International Journal of Extreme Manufacturing2020，2，3： | 9 |

| 4 | Quasi-phase-matching-division multiplexing holography in a three-dimensional nonlinear photonic crystal显示文摘Nonlinear holography has recently emerged as a novel tool to reconstruct the encoded information at a new wavelength,which has important applications in optical display and optical encryption.However,this scheme still struggles with low conversion efficiency and ineffective multiplexing.In this work,we demonstrate a quasi-phasematching(QPM)-division multiplexing holography in a three-dimensional(3D)nonlinear photonic crystal(NPC).3D NPC works as a nonlinear hologram,in which multiple images are distributed into different Ewald spheres in reciprocal space.The reciprocal vectors locating in a given Ewald sphere are capable of fulfilling the complete QPM conditions for the high-efficiency reconstruction of the target image at the second-harmonic(SH)wave.One can easily switch the reconstructed SH images by changing the QPM condition.The multiplexing capacity is scalable with the period number of 3D NPC.Our work provides a promising strategy to achieve highly efficient nonlinear multiplexing holography for high-security and high-density storage of optical information. | Pengcheng Chen Chaowei Wang Dunzhao Wei Yanlei Hu Xiaoyi Xu Jiawen Li Dong Wu Jianan Ma Shengyun Ji Leran Zhang Liqun Xu Tianxin Wang Chuan Xu Jiaru Chu Shining Zhu Min Xiao Yong Zhang | 2021 | Light(Science & Applications)2021，10，8： | 5 |
| 5 | Efficient full-path optical calculation of scalar and vector diffraction using the Bluestein method显示文摘Efficient calculation of the light diffraction in free space is of great significance for tracing electromagnetic field propagation and predicting the performance of optical systems such as microscopy,photolithography,and manipulation.However,existing calculation methods suffer from low computational efficiency and poor flexibility.Here,we present a fast and flexible calculation method for computing scalar and vector diffraction in the corresponding optical regimes using the Bluestein method.The computation time can be substantially reduced to the sub-second level,which is 105 faster than that achieved by the direct integration approach(~hours level)and 102 faster than that achieved by the fast Fourier transform method(~minutes level).The high efficiency facilitates the ultrafast evaluation of light propagation in diverse optical systems.Furthermore,the region of interest and the sampling numbers can be arbitrarily chosen,endowing the proposed method with superior flexibility.Based on these results,full-path calculation of a complex optical system is readily demonstrated and verified by experimental results,laying a foundation for real-time light field analysis for realistic optical implementation such as imaging,laser processing,and optical manipulation. | Yanlei Hu Zhongyu Wang Xuewen Wang Shengyun Ji Chenchu Zhang Jiawen Li Wulin Zhu Dong Wu Jiaru Chu | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 6 | Dynamic Airy imaging through high_efficiency broadband phase microelements by femtosecond laser direct writing显示文摘Manipulating Airy beams to symmetric Airy beams(SABs)with abruptly autofocusing and self accelerating properties has attracted much attention.With such a particular propagation dynamic,SABs may provide great potential in dynamic signal imaging.On the other hand,the generation of SABs by spatial light modulators suffers from the limitations of phase gradient accuracy,low optical efficiency(<40%),and a bulky footprint.Therefore,exploring imaging applications and optimal generation methods of these Airy-type beams deserves further research.Here,based on the coordinate transformation of SAB,an asymmetric Airy beam(AAB)is realized.Symmetric/asymmetric cubic phase microplates(SCPPs/ACPPs)are designed and fabricated for generating SAB/AAB.The SCPP/ACPP demonstrates superior performance:compact construction(60μm × 60μm × 1.1μm),continuous variation of phase,high efficiency(~81%at 532 nm),and broadband operation from 405 to 780 nm.Dynamic imaging under monochromatic and polychromatic lights is realized by the SAB/AAB,indicating various results at different propagation distances with a certain initial signal.Further investigation reveals that the SCPP on a soft substrate maintains its physical dimensions and optical properties unchanged during stretching.Our work enables wide potential applications in integrated optics,beam manipulation,and imaging. | ZE CAI XINBO QI DENG PAN SHENGYUN JI JINCHENG NI ZHAOXIN LAO CHEN XIN JIAWEN LI YANLEI HU DONG Wu JIARU CHI | 2020 | Photonics Research2020，8，6： | 3 |
| 7 | Surface composition dominates the electrocatalytic reduction of CO2 on ultrafine CuPd nanoalloys显示文摘Preciously tuning the surface composition of noble metal nanoparticles with the particle size of only 2 nm or less by alloying with other metals represents a powerful strategy to boost their electrocatalytic selectivity.However,the synthesis of ultrafine nanoalloys and tuning their surface composition remain challenging.In this report,ultrafine CuPd nanoalloys with the particle size of ca.2 nm are synthesized based on the galvanic replacement reaction between presynthesized Cu nanoparticles and Pd2+precursors,and the tuning of their surface compositions is also achieved by changing the atom ratios of Cu/Pd.For the electrocatalytic reduction of CO2,Cu5Pd5 nanoalloys show the CO Faradaic efficiency(FE)of 88%at−0.87 V,and the corresponding mass activity reaches 56 A/g that is much higher than those of Cu8Pd2 nanoalloys,Cu3Pd7 nanoalloys and most of previously reported catalysts.Density functional theory uncovers that with the increase of Pd on the surface of the ultrafine CuPd nanoalloys,the adsorbed energy of both of intermediate COOH*and CO*to the Pd sites is strengthened.The Cu5Pd5 nanoalloys with the optimal surface composition better balance the adsorption of COOH*and desorption of CO*,achieving the highest selectivity and activity.The difficult liberation of absorbed CO*on the surface of Cu3Pd7 nanoalloys provides carbon source to favor the production of ethylene,endowing the Cu3Pd7 nanoalloys with the highest selectivity for ethylene among these ultrafine CuPd nanoalloys. | Dong Chen Yanlei Wang Danye Liu Hui Liu Cheng Qian Hongyan He Jun Yang | 2020 | Carbon Energy2020，2，3： | 3 |
| 8 | MicroRNA-628-5p Facilitates Enterovirus 71 Infection by Suppressing TRAF3 Signaling显示文摘To date,EV71 infection still poses a great challenge to the health of infants and young children.1 Much established evidence suggests that EV71 infection depends on a wide variety of host factors,including cell surface receptors for EV71 entry,innate immune response,miRNAs,and lncRNAs.2,3 It is thought that diverse signaling pathways are required for EV71 to escape the host immune response.4 Innate immunity serves as the first line of defense against pathogens.Tumor necrosis factor receptor-associated factor(TRAF)proteins are essential components of signaling pathways activated by Toll-like receptor(TLR)or RIG-I-like receptor(RLR)family members.TRAF3 is widely expressed by many cell types,including all nucleated immune cells,in which it plays many roles in the regulation of immune functions.5 TRAF3 plays a significant role in regulating the functions of B and T lymphocytes.TRAF3 is a highly versatile regulator that positively controls type I interferon and cytokine production through interferon regulatory factors(IRFs)and nuclear factor-κB(NF-κB).6 A recent study indicated that EV71-induced ubiquitin-specific protease 19(USP19)negatively regulates type I IFN signaling by targeting TRAF3. | Dong Li Shuaiyin Chen Weiguo Zhang Chao Zhang Tiantian Sun Yue Du Ronghua Ding Yanlei Gao Yuefei Jin Guangcai Duan | 2021 | Cellular & Molecular Immunology2021，18，5： | 2 |

| 13 | Reply to Comments on “Efficient full-path optical calculation of scalar and vector diffraction using the Bluestein method”显示文摘Dear Editor,In ref.we present an efficient full-path optical calculation by using the Bluestein method.A real optical apparatus for laser processing,imaging,or optical tweezing normally involves diverse optical lenses with different physical and numerical apertures(NA).In such applications,the optical path is usually tortuous and long.To assist in the design,evaluation,and alignment of optical instruments,it is advantageous to retrieve the optical field in an arbitrary position along the entire optical path,which is termed the full-path calculation in our paper,with sufficient accuracy and efficiency.In particular,high flexibility is required to accommodate the mismatch between optical apertures of different components in the optical path.We present a fullpath optical calculation method by adopting the Bluestein method to address this realistic demand. | Yanlei Hu Zhongyu Wang Xuewen Wang Shengyun Ji Chenchu Zhang Jiawen Li Wulin Zhu Dong Wu Jiaru Chu | 2021 | Light(Science & Applications)2021，10，1： | 0 |

| 15 | ENO1 expression and Erk phosphorylation in PDAC and their effects on tumor cell apoptosis in a hypoxic microenvironment显示文摘Objective: Hypoxia is an important feature of pancreatic ductal adenocarcinoma(PDAC). Previously, we found that hypoxia promotes ENO1 expression and PDAC invasion. However, the underlying molecular mechanism was remains unclear.Methods: The relationship between ENO1 expression and clinicopathological characteristics was analyzed in 84 patients with PADC. The effects of CoCl2-induced hypoxia and ENO1 downregulation on the apoptosis, invasion, and proliferation of PDAC cells were evaluated in vitro and in vivo. Hypoxia-and ENO1-induced gene expression was analyzed by transcriptomic sequencing.Results: The prognosis of PDAC with high ENO1 expression was poor(P < 0.05). High ENO1 expression was closely associated with histological differentiation and tumor invasion in 84 PDAC cases(P < 0.05). Hypoxia increased ENO1 expression in PDAC and promoted its migration and invasion. Apoptotic cells and the apoptosis marker caspase-3 in the CoCl_(2)-treated ENO1-sh group were significantly elevated(P < 0.05). Transcriptomic sequencing indicated that CoCl_(2)-induced PDAC cells initiated MAPK signaling. Under hypoxic conditions, PDAC cells upregulated ENO1 expression, thereby accelerating ERK phosphorylation and inhibiting apoptosis(P < 0.05). Consistent results were also observed in a PDAC-bearing mouse hindlimb ischemia model.Conclusions: Hypoxia-induced ENO1 expression promotes ERK phosphorylation and inhibits apoptosis, thus leading to PDAC survival and invasion. These results suggest that ENO1 is a potential therapeutic target for PDAC. | Huizhi Sun Jing Mo Runfen Cheng Fan Li Yue Li Yuhong Guo Yanlei Li Yanhui Zhang Xiaoyu Bai Yalei Wang Xueyi Dong Danfang Zhang Jihui Hao | 2022 | Cancer Biology & Medicine2022，19，11： | 0 |
| 16 | VEGFA rs3025039 and biliary atresia susceptibility in Chinese population:a systematic review and meta-analysis显示文摘Background Previous studies have suggested an association between vascular endothelial growth factor A(VEGFA)rs3025039 polymorphism and biliary atresia(BA).However,this conclusion is controversial and there is no published pooled evidence of this association.Methods This study was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.The protocol was registered with PROSPERO(International Prospective Register of Systematic Reviews).A thorough search was performed on databases including PubMed,Embase,and Chinese Biomedical Database up to August 2020.This study included 846 cases of BA and 2821 controls concerning VEGFA rs3025039 polymorphism.We selected relevant studies based on the following inclusion criteria:(1)the study design was case-control and cohort and(2)the patients carried standard clinical diagnoses of BA,etc.The exclusion criteria were as follows:(1)patients with other related diseases,(2)lack of requisite information and(3)duplicate data.The OR(odd ratio)and the corresponding 95%CI(confidence interval)were calculated to estimate the association.Results This study on VEGFA rs3025039 polymorphism in the Chinese population included 846 cases and 2821 controls.The results showed that there was no significant association between rs3025039 and susceptibility to BA under four genetic models.The results of the subgroup analysis were similar to the overall results.Conclusions This meta-analysis shows that rs3025039 was not associated with susceptibility to BA in the Chinese population.Further validation may entail additional research.PROSPERO registration number CRD42020203812. | Shiwei He Yifan Yang Lingdu Meng Gong Chen Yanlei Huang Zhen Shen Rui Dong Shan Zheng | 2022 | World Journal of Pediatric Surgery2022，5，1： | 0 |
| 17 | Femtosecond laser direct writing of functional stimulus-responsive structures and applications显示文摘Diverse natural organisms possess stimulus-responsive structures to adapt to the surrounding environment.Inspired by nature,researchers have developed various smart stimulus-responsive structures with adjustable properties and functions to address the demands of ever-changing application environments that are becoming more intricate.Among many fabrication methods for stimulus-responsive structures,femtosecond laser direct writing(FsLDW)has received increasing attention because of its high precision,simplicity,true three-dimensional machining ability,and wide applicability to almost all materials.This paper systematically outlines state-of-the-art research on stimulus-responsive structures prepared by FsLDW.Based on the introduction of femtosecond laser-matter interaction and mainstream FsLDW-based manufacturing strategies,different stimulating factors that can trigger structural responses of prepared intelligent structures,such as magnetic field,light,temperature,pH,and humidity,are emphatically summarized.Various applications of functional structures with stimuli-responsive dynamic behaviors fabricated by FsLDW,as well as the present obstacles and forthcoming development opportunities,are discussed. | Yuxuan Zhang Dong Wu Yachao Zhang Yucheng Bian Chaowei Wang Jiawen Li Jiaru Chu Yanlei Hu | 2023 | International Journal of Extreme Manufacturing2023，5，4： | 0 |
| 18 | Shale Lithofacies and Sedimentary Environment of the Third Member,Shahejie Formation,Zhanhua Sag,Eastern China显示文摘Researches into shale lithofacies,their sedimentary environments and relationship benefit understanding both of sedimentary cycle division and unconventional hydrocarbon exploration in lacustrine basins.Based on a 100~300-m-thick dark shale,mudstone and limestone encountered in the lower third member of the Eocene Shahejie Formation(Es3l member)in Zhanhua Sag,Bohai Bay Basin,eastern China,routine core analysis,thin sectioning,scanning electron microscopy(SEM),mineralogical and geochemical measurements were used to understand detailed facies characterization and paleoclimate in the member.This Es3l shale sediment includes three sedimentary cycles(C3,C2 and C1),from bottom to top,with complex sedimentary characters and spatial distribution.In terms of the composition,texture,bedding and thickness,six lithofacies are recognized in this succession.Some geochemical parameters,such as trace elements(Sr/Ba,Na/Al,V/Ni,V/(V+Ni),U/Th),carbon and oxygen isotopes(δ^(18)O,δ^(13)C),and total organic carbon content(TOC)indicate that the shales were deposited in a deep to semi-deep lake,with the water column being salty,stratified,enclosed and reductive.During cycles C3 and C2 of the middle-lower sections,the climate was arid,and the water was salty and stratified.Laminated and laminar mudstone-limestone was deposited with moderate organic matter(average TOC 1.8%)and good reservoir quality(average porosity 6.5%),which can be regarded as favorable reservoir.During the C1 cycle,a large amount of organic matter was input from outside the basin and this led to high productivity with a more humid climate.Massive calcareous mudstone was deposited,and this is characterized by high TOC(average 3.6%)and moderate porosity(average 4%),and provides favorable source rocks. | ZHU Xiaomin ZHANG Meizhou ZHU Shifa DONG Yanlei LI Chao BI Yuequan MA Lichi | 2022 | Acta Geologica Sinica(English Edition)2022，96，3： | 0 |
| 19 | Multilayered skyscraper microchipsfabricated by hybrid “all-in-one”femtosecond laser processing显示文摘Multilayered microfluidic channels integrated with functional microcomponents are the general trend of future biochips,which is similar to the history of Si-integrated circuits from the planer to the three-dimensional(3D)configuration,since they offer miniaturization while increasing the integration degree and diversifying the applications in the reaction,catalysis,and cell cultures.In this paper,an optimized hybrid processing technology is proposed to create true multilayered microchips,by which“all-in-one”3D microchips can be fabricated with a successive procedure of 3D glass micromachining by femtosecond-laser-assisted wet etching(FLAE)and the integration of microcomponents into the fabricated microchannels by two-photon polymerization(TPP).To create the multilayered microchannels at different depths in glass substrates(the top layer was embedded at 200μm below the surface,and the underlying layers were constructed with a 200-μm spacing)with high uniformity and quality,the laser power density(13~16.9 TW/cm^(2))was optimized to fabricate different layers.To simultaneously complete the etching of each layer,which is also important to ensure the high uniformity,the control layers(nonlaser exposed regions)were prepared at the upper ends of the longitudinal channels.Solvents with different dyes were used to verify that each layer was isolated from the others.The high-quality integration was ensured by quantitatively investigating the experimental conditions in TPP,including the prebaking time(18~40 h),laser power density(2.52~3.36 TW/cm2)and developing time(0.8~4 h),all of which were optimized for each channel formed at different depths.Finally,the eightlayered microfluidic channels integrated with polymer microstructures were successfully fabricated to demonstrate the unique capability of this hybrid technique. | Chaowei Wang Liang Yang Chenchu Zhang Shenglong Rao Yulong Wang SizhuWu Jiawen Li Yanlei Hu Dong Wu Jiaru Chu Koji Sugioka | 2019 | Microsystems & Nanoengineering2019，5，1： | 0 |
