| 1 | Analysis of the element content in poplar tree leaves by femtosecond laser-induced breakdown spectroscopy显示文摘Femtosecond laser-induced breakdown spectroscopy (fs-LIBS) is employed to analyze the element content in poplar tree leaves from four representative locations in Changchun City (Jingyue National Forest Park,JYP),Changchun University of Science and Technology (CUST),Casting Factory (CF) and Forging Factory (FF) of First Automobile Works (FAW) under identical experimental conditions.Those elements of N,P,K,Ca,Fe,Ti,Mn and Na are identified in the poplar tree leaves from the recorded spectrogram and the elemental content in the leaves is further obtained by applying free calibration method to the spectrogram.Our results show that the elements Ca and Fe in the poplar tree leaves from the CF area have the highest concentration in the four locations,which is a factor of 2.05 and 1.66 respectively to those of JYP.This experiment demon-strates that fs-LIBS can be utilized to analyze element content in a sample and find new applications in the environmental detection. | MA Shuang GAO Xun GUO KaiMin KAHSAY Medhanie LIN JingQuan | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，11： | 8 |

| 5 | A flexible neural implant with ultrathin substrate for low-invasive brain–computer interface applications显示文摘Implantable brain–computer interface(BCI)devices are an effective tool to decipher fundamental brain mechanisms and treat neural diseases.However,traditional neural implants with rigid or bulky cross-sections cause trauma and decrease the quality of the neuronal signal.Here,we propose a MEMS-fabricated flexible interface device for BCI applications.The microdevice with a thin film substrate can be readily reduced to submicron scale for low-invasive implantation.An elaborate silicon shuttle with an improved structure is designed to reliably implant the flexible device into brain tissue.The flexible substrate is temporarily bonded to the silicon shuttle by polyethylene glycol.On the flexible substrate,eight electrodes with different diameters are distributed evenly for local field potential and neural spike recording,both of which are modified by Pt-black to enhance the charge storage capacity and reduce the impedance.The mechanical and electrochemical characteristics of this interface were investigated in vitro.In vivo,the small cross-section of the device promises reduced trauma,and the neuronal signals can still be recorded one month after implantation,demonstrating the promise of this kind of flexible BCI device as a low-invasive tool for brain–computer communication. | Zhejun Guo Fang Wang Longchun Wang Kejun Tu Chunpeng Jiang Ye Xi Wen Hong Qingda Xu Xiaolin Wang Bin Yang Bomin Sun Zude Lin Jingquan Liu | 2022 | Microsystems & Nanoengineering2022，8，6： | 1 |
| 6 | Disclosing transverse spin angular momentum of surface plasmon polaritons through independent spatiotemporal imaging of its in-plane and out-of-plane electric field components显示文摘The comprehensive capture of near field spatiotemporal information of surface plasmon polaritons(SPPs)is a prerequisite for revealing their physical nature.In this study,we first performed an independent,spatiotemporal imaging of the out-of-plane and in-plane components of SPP near fields in a femtosecond light-excited trench using an obliquely incident time-resolved photoemission electron microscopy(TR-PEEM).We did the capture by imaging of the interference patterns induced by a superposition of the p-or s-polarized probe light,with the out-plane or in-plane components of SPP near-fields,under the noncollinear excitation mode.The method may be used to reconstruct a 3D SPP spatiotemporal field.Moreover,we demonstrated that the fringe shift of the in-terference patterns between the captured in plane and out-of plane components of the SPP field in PEEM images corresponds to the 1/4 fringe period,which is attributed toπ/2 out of phase of the out-of plane and in-plane near-field components of SPP.The resulting TR-PEEM images are supported by a classical wave mode and FDTD simulations.Essentially,the measuredπ/2 phase difference between the in-plane and out-of plane components of the SPP indicated a rotating field component in the propagation plane,i.e,that the SPP exhibits an elliptically polarized electric field in the propagation plane.The experimental results presented herein provide direct evidence of SPP having the inherent attributes of transverse spin angular momentum. | YULU QIN BOYU JI XIAOWEI SONG JINGQUAN LIN | 2020 | Photonics Research2020，8，6： | 1 |

| 8 | Femtosecond laser micro-nano processing for boosting bubble releasing of gas evolution reactions显示文摘Coupling effect of chemical composition and physical structure is a key factor to construct superaerophobic electrodes.Almost all reports about superaerophobic electrodes were aimed at precisely controlling morphology of loaded materials(constructing specific structure)and ignored the due role of substrate.Nevertheless,in this work,by using high precision and controllable femtosecond laser,hierarchical micro-nano structures with superaerophobic properties were constructed on the surface of silicon substrate(fs-Si),and such special super-wettability could be successfully inherited to subsequent self-supporting electrodes through chemical synthesis.Femtosecond laser processing endowed electrodes with high electrochemical surface area,strong physical structure,and remarkable superaerophobic efficacy.As an unconventional processing method,the reconstructed morphology of substrate surface bears the responsibility of superaerophobicity,thus liberating the structural constraints on loaded materials.Since this key of coupling effect is transferred from the loaded materials to substrate,we provided a new general scheme for synthesizing superaerophobic electrodes.The successful introduction of femtosecond laser will open a new idea to synthesize self-supporting electrodes for gas-involving reactions. | Shuai Zhang Lishuang Xu Jie Wu Ying Yang Chengxin Zhang Haiyan Tao Jingquan Lin Licheng Huang Wencheng Fang Keying Shi Xiangting Dong | 2022 | Nano Research2022，15，2： | 0 |
| 9 | Flexible manipulation of plasmon dephasing time via the adjustable Fano asymmetric dimer显示文摘It is highly desirable to flexibly and actively manipulate the dephasing time of a plasmon in many potential applications;however,this remains a challenge.In this work,by using femtosecond time-resolved photoemission electron microscopy,we experimentally demonstrated that the Fano resonance mode in the asymmetric nanorod dimer can greatly extend the dephasing time of a femtosecond plasmon,whereas the non-Fano resonance results in a smaller dephasing time due to the large radiative damping,and flexible manipulation of the dephasing time can be realized by adjusting one of the nanorods in the Fano asymmetric dimer.Interestingly,it was found that plasmon resonance wavelengths both appeared red-shifted as the length of the upper or lower nanorods increased individually,but the dephasing time varied.Furthermore,it also indicated that the dephasing time can be prolonged with a smaller ascending rate by increasing the length of both the nanorods simultaneously while keeping the dimer asymmetry.Meanwhile,the roles of radiative and nonradiative damping in dephasing time are unveiled in the process of nanorod length variation.These results are well supported by numerical simulations and calculations. | YANG XU YULU QIN PENG LANG BOYU JI XIAOWEI SONG JINGQUAN LIN | 2022 | Photonics Research2022，10，10： | 0 |
| 10 | Ultrafast spatiotemporal control of directional launching of surface plasmon polaritons in a plasmonic nano coupler显示文摘Ultrafast spatiotemporal control of a surface plasmon polariton(SPP)launch direction is a prerequisite for ultrafast information processing in plasmonic nanocircuit components such as ultrafast on–off of plasmonic switching and information recording.Here we realize for the first time,to the best of our knowledge,ultrafast spatiotemporal control of the preferential launch direction of an SPP at the nano-femtosecond scale via a plasmonic nano directional coupler.The spatiotemporal switching of the SPP field was revealed using time-resolved photoemission electron microscopy(TR-PEEM).Experimental results show that the extinction ratio of the SPP directional coupler can be substantially optimized by properly selecting the amplitude and time delay of the two incident light pulses in the experiment.More importantly,we demonstrate a solution for the launch direction of the SPP field,switched in a plasmonic nano directional coupler on the femtosecond timescale,by adjusting the instantaneous polarization state of the excitation light.The TR-PEEM images are supported by finite-difference time-domain(FDTD)simulations.We believe the results of this study can be used to develop high-speed,miniaturized signal processing systems. | Yulu Qin Boyu Ji Xiaowei Song Jingquan Lin | 2021 | Photonics Research2021，9，4： | 0 |
