| 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 |

| 3 | 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 |
| 4 | Crystalline behaviors and phase transition during the manufacture of fine denier PA6 fibers显示文摘Recently we have successfully produced fine denier PA6 fibers by using additives containing lanthanide compounds.Meanwhile,crystallization and phase transition of PA6 fibers during spinning and drawing processes were investigated.During the spinning process,β phase crystal could be obtained in as-spun PA6 fibers which were produced with relatively high melt draw ratio,while γ phase crystal predominated when the melt draw ratio was relatively low.β phase crystal,whose behaviors are similar with those of γ phase by FT-IR and XRD characterization,could be transformed to α form easily when PA6 fibers are immersed in boiling water.However,γ phase crystal of PA6 remains unchanged in boiling water.Thus,β and γ phase crystals of PA6 can be differentiated by the crystalline behaviors of PA6 fibers after treatment in boiling water.Further experiments demonstrate that the β phase can also be produced during a drawing process where a phase transformation from γ to α occurs.In other words,β phase may act as an intermediate state during the phase transformation. | ZHANG ChengFeng LIU YuHai LIU ShaoXuan LI HuiZhen HUANG Kun PAN QingHua HUA XiaoHui HAO ChaoWei MA QingFang LV ChangYou LI WeiHong YANG ZhanLan ZHAO Ying WANG DuJin LAI GuoQiao JIANG JianXiong XU YiZhuang WU JinGuang | 2009 | Science China Chemistry2009，52，11： | 4 |
| 5 | Surfactant-Encapsulated Polyoxometalate Complex as a Cathode Interlayer for Nonfullerene Polymer Solar Cells显示文摘An alcohol-soluble,environmentally friendly,and low-cost surfactant-encapsulated polyoxometalate complex[(C8H17)4N]4[SiW_(12)O40](TOASiW_(12))as a cathode interlayer(CIL)has exhibited excellent universality for various active layers and cathodes in nonfullerene polymer solar cells(NF-PSCs).In particular,incorporating TOASiW_(12) as the CIL enhanced power conversion efficiencies(PCEs)of the PM6:Y6-based NF-PSCs with Al or Ag cathode to 16.14%and 15.89%,respectively,and the PCEs of PM6:BTP-BO4Cl-based NF-PSCs with Al or Ag cathode to 17.04%and 17.00%,respectively.More importantly,the performances of the devices with TOASiW_(12) were insensitive to the TOASiW_(12) thickness from 3 to 33 nm.Furthermore,the NF-PSCs with TOASiW_(12) exhibited better device stability.Combined characterization of the photocurrent density versus effective voltage,capacitance versus voltage and electron mobility demonstrated that TOASiW_(12) as the CIL effectively promoted exciton dissociation,charge-carrier extraction,built-in potential,charge-carrier density,and electron mobility in the NF-PSCs.These findings suggest that TOASiW_(12) is a promising,competitive CIL for NF-PSCs fabricated by roll-to-roll processing. | Jing Qiu Yue Zhang Yan Liu Huiru Liu Dongdong Xia Fan Yang Chaowei Zhao Weiwei Li Lixin Wu Fenghong Li | 2022 | CCS Chemistry2022，4，3： | 3 |
| 6 | A method of forced extrapolation of the global magnetic field in the solar corona显示文摘We present a method of forced-field(i.e., non-force-free field: NFFF) extrapolation of the global magnetic field in the corona, on the basis of single-layer vector magnetogram, by extending an extrapolation technique of local magnetic field first developed by Hu et al.(2008). The forced coronal magnetic field is described by a system with the minimum dissipation rate(MDR) which is appropriate for the corona as a forced and open system. The obtained solution of the magnetic field can be decomposed into three components including one potential field and two linear force-free fields(LFFF). Starting from the given single-layer vector magnetogram, the bottom boundary condition for each component is determined with an iterative method to achieve a minimum difference of the transverse component between the extrapolated field and the original magnetogram. The final extrapolated forced field is given by the sum of the three component fields with the obtained bottom boundaries. The method is tested with an analytic magnetohydrostatic(MHS) solution. It is shown that the extrapolated forced field is highly consistent with the MHS solution at least from the solar disk to the heliocentric distance of 1.5 solar radii(R⊙). For instance, the complements of normalized and mean vector errors(E’n, E’m) are as high as ~97% and 95%, respectively. Further comparisons between magnetic strength, force and field line distributions indicate that the MHS solution has been successfully reconstructed. | WANG Bing CHEN Yao HU Qiang JIANG ChaoWei SONG HongQiang WU Zhao NING Hao | 2020 | Science China(Technological Sciences)2020，63，2： | 3 |

| 10 | An Organic–Inorganic Hybrid Material Based on Benzo[ghi]perylenetri-imide and Cyclic Titanium-Oxo Cluster for Efficient Perovskite and Organic Solar Cells显示文摘Perovskite and organic solar cells usually require electron-transport interlayers to efficiently transport electrons from the photoactive layer to the metal electrode.In general,pure organic or inorganic materials are applied into the interlayers,but organic–inorganic hybrid materials have been rarely reported for this application.In this work,we report using the first titanium-oxo cluster-based organic–inorganic hybrid as the interlayer material by introducing largeπ-conjugated benzo[ghi]perylenetriimides as an organic part via a simple ligand-exchange reaction.This new hybrid material showed excellent solubility,well-aligned energy levels,and excellent electron mobilities,enabling its great potential application as an interlayer in solar cells such as perovskite and organic solar cells,providing high power conversion efficiencies of>20%and 16%,respectively.Therefore,we claim that our present work introduces a new class of cluster-based organic–inorganic hybrid interlayer materials that exhibit promising application in organic electronics. | Zhou Zhang Faming Han Jie Fang Chaowei Zhao Shuai Li Yonggang Wu Yuefeng Zhang Shengyong You Binghui Wu Weiwei Li | 2022 | CCS Chemistry2022，4，3： | 1 |

| 14 | Effi cient long-distance NMR-PRE and EPR-DEER restraints for two-domain protein structure determination显示文摘Dear Editor,The functional diversity of proteins is related to the cooperation of multiple domains.Independent globular domains are typically joined by a fl exible length of polypeptide chain,which makes the structural analysis of multi-domain proteins diffi cult.Here,we describe the combined use of solution NMR(nuclear magnetic resonance)and EPR(elec-tron paramagnetic resonance)for the structural analysis of a protein with two separate domains.The structure of each domain was determined independently using conventional NMR restraints,and the relative orientation of the two separate domains was confi ned using long-distance restraints obtained by NMR-PRE(paramagnetic relaxation enhancement)and EPR-DEER(double electron-electron resonance,also called PELDOR:pulsed electron double reso-nance. | Kaiqi Wu Chaowei Shi Juan Li Haipeng Wang Pan Shi Liu Chen Fangming Wu Ying Xiong Changlin Tian | 2013 | Protein & Cell2013，4，12： | 0 |

| 16 | Growth of boron nitride nanotubes from magnesium-based catalysts显示文摘This study reports an efficient method for growing high-quality boron nitride nanotubes(BNNTs)via chemical vapor deposition of low-melting-point precursors—magnesium diboride(MgB_(2)),magnesium nitride(Mg_(3)N_(2)),and diboron trioxide(B_(2)O)at a growth temperature of 1000–1300℃.The strong oxygen-capturing ability of Mg_(3)N_(2)inhibits the formation of high-melting-point Mg_(3)B_(2)O_(6),which helps MgB_(2)to maintain an efficient and stable catalytic capacity,thereby enhancing its growth efficiency and utilization of the boron source.Moreover,polydimethylsiloxane(PDMS)composites formed from these BNNTs demonstrated much greater thermal conductivities than pure PDMS.Thus,this novel strategy for preparing BNNTs is efficient,and they have great potential for application as thermal interface materials. | Ying Wang Kai Zhang Liyun Wu Xuhua He Qian He Nanyang Wang Zhengyang Zhou Chaowei Li Yue Hu Yagang Yao | 2023 | Nano Research2023，16，8： | 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 | Stable Radical TEMPO Terminated Perylene Bisimide(PBI) Based Small Molecule as Cathode Interlayer for Efficient Organic Solar Cells显示文摘By combining stable radical tetramethylpiperidine nitrogen oxide(TEMPO)as end groups and perylene bisimide(PBI)as the core,a small molecular cathode interlayer(CIL)(PBI-TEMPO)was synthesized.Detailed physical-chemical characterizations indicate that PBI-TEMPO can form smooth film,owns low unoccupied molecular orbital(LUMO)level of−3.67 eV and can reduce the work function of silver electrode.When using PBI-TEMPO as CIL in non-fullerene organic solar cells(OSCs),the PM6:BTP-4Cl based OSCs delivered high power conversion efficiencies(PCEs)up to 17.37%,higher than those using commercial PDINO CIL with PCEs of 16.95%.Further device characterizations indicate that PBI-TEMPO can facilitate more efficient exciton dissociation and reduce charge recombination,resulting in enhanced current density and fill factor.Moreover,PBI-TEMPO displays higher thermal stability than PDINO in solution.When PBI-TEMPO and PDINO solution were heated at 150℃ for 2 h and then were used as CIL in solar cells,PBI-TEMPO-based OSCs provided a PCE of 15%,while PDINO-based OSCs only showed a PCE of 10%.These results demonstrate that incorporating TEMPO into conjugated materials is a useful strategy to create new organic semiconductors for application in OSCs. | ZHANG Ziwei XIA Dongdong XIE Qian ZHAO Chaowei FANG Jie WU Yonggang LI Weiwei | 2023 | Chemical Research in Chinese Universities2023，39，2： | 0 |
| 19 | A wireless-communication-based measurement of gas pressure with capsule-slime sealing device显示文摘To solve the existing problems of imperfect sealing and the inaccurate measurement of gas pressure in traditional sealing,the present study builds a new model of capsule-slime sealing device based on wireless pressure gauge.The new sealing device is mainly composed of two sets of capsules,a capsule connecting piece and a slime part,measures the pressure through the wireless communication technology,and seals through chemical reaction in the capsule,which generates gas to expand the capsule and extrude the pre-stored slime.Two methods of extruding pre-stored slime are proposed:in the first method,transverse force is generated by the expansion of the capsules at both ends,pushing the capsules toward the middle through the chute and squeezing the pre-stored slime out;in the second,high-pressure gas generated in the capsules is led into the expansion tube,which is inserted into the storage tube,squeezing it and letting the slime out to complete the sealing process.Then the research studies the effect of sealing under the condition of drilling with the structure of slime storage tube.The results indicate that the maximum standing time of slime wrapped in metal net is 2 h,instead of the expected 10 d,failing to meet the sealing requirements.When the slime viscosity is 1200–3000 m Paás in the structure of slime storage tube,the best viscosity of slime is achieved and can simulate sealing the drilling hole(5–4,4–2.36,2.36–1.18,1.18–0.15 mm in diameter),as well as the gap caused by mixed sand accumulation. | Zhengyan Wu Deqiang Fan Shuguang Jiang Hao Shao Kai Wang Weiqing Zhang Chaowei Guo | 2019 | International Journal of Mining Science and Technology2019，29，6： | 0 |
| 20 | 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 |
