| 1 | A Sub-Nanostructural Transformable Nanozyme for Tumor Photocatalytic Therapy显示文摘The structural change-mediated catalytic activity regulation plays a significant role in the biological functions of natural enzymes.However,there is virtually no artificial nanozyme reported that can achieve natural enzyme-like stringent spatiotemporal structure-based catalytic activity regulation.Here,we report a subnanostructural transformable gold@ceria(STGC-PEG)nanozyme that performs tunable catalytic activities via near-infrared(NIR)light-mediated sub-nanostructural transformation.The gold core in STGC-PEG can generate energetic hot electrons upon NIR irradiation,wherein an internal sub-nanostructural transformation is initiated by the conversion between CeO;and electron-rich state of CeO;-x,and active oxygen vacancies generation via the hot-electron injection.Interestingly,the sub-nanostructural transformation of STGC-PEG enhances peroxidase-like activity and unprecedentedly activates plasmon-promoted oxidase-like activity,allowing highly efficient low-power NIR light(50 m W cm;)-activated photocatalytic therapy of tumors.Our atomic-level design and fabrication provide a platform to precisely regulate the catalytic activities of nanozymes via a light-mediated sub-nanostructural transformation,approaching natural enzyme-like activity control in complex living systems. | Xi Hu Nan Wang Xia Guo Zeyu Liang Heng Sun Hongwei Liao Fan Xia Yunan Guan Jiyoung Lee Daishun Ling Fangyuan Li | 2022 | Nano-Micro Letters2022，14，6： | 4 |
| 2 | Development of an autonomous flapping-wing aerial vehicle显示文摘The flapping-wing aerial vehicle(FWAV) has appealed to more and more researchers recently owing to its outstanding performance in various domains and the development of some related technologies. The research on autonomous flight control of the FWAV involves many challenges and is still in nascent stages. In this work, we develop an FWAV with a mass of 14.1 g and build a vision-based experimental platform. A modelbased controller is proposed on the basis of theory and simulation results prove its effectiveness. A PID control algorithm based on visual measurement is utilized to achieve the height-keeping control of the FWAV, and a software platform is designed to record the flight status determined using Euler angles and position information. | Wei HE Haifeng HUANG Yunan CHEN Wenzhen XIE Fusen FENG Yemeng KANG Changyin SUN | 2017 | Science China(Information Sciences)2017，60，6： | 3 |

| 4 | Adaptive Iterative Learning Control for a Class of Nonlinear Time-varying Systems with Unknown Delays and Input Dead-zone显示文摘This paper presents an adaptive iterative learning control(AILC) scheme for a class of nonlinear systems with unknown time-varying delays and unknown input dead-zone.A novel nonlinear form of dead-zone nonlinearity is presented.The assumption of identical initial condition for iterative learning control(ILC) is removed by introducing boundary layer function.The uncertainties with time-varying delays are compensated for by using appropriate Lyapunov-Krasovskii functional and Young’s inequality.Radial basis function neural networks are used to model the time-varying uncertainties.The hyperbolic tangent function is employed to avoid the problem of singularity.According to the property of hyperbolic tangent function,the system output is proved to converge to a small neighborhood of the desired trajectory by constructing Lyapunov-like composite energy function(CEF) in two cases,while keeping all the closedloop signals bounded.Finally,a simulation example is presented to verify the effectiveness of the proposed approach. | Jianming Wei Yunan Hu Meimei Sun | 2014 | IEEE/CAA Journal of Automatica Sinica2014，1，3： | 3 |

| 8 | Design of low-pass filter with 3-interations Koch fractal Pi-shaped DGS显示文摘A novel asymmetrical Pi-shaped defected ground structure( DGS) with 3-interations Koch fractal curves is proposed to design a microstrip low-pass filter( LPF) with ultra-wide stop-band( SB). The proposed LPFs with a single resonator and two cascaded resonators are both designed,simulated,manufactured and measured. Simulation and experiment results demonstrate that the designed LPF has a very sharp transition band( TB) and an ultra-wide SB performance compared with the existed similar symmetrical and asymmetrical DGS. The proposed LPF with two cascaded resonators is with a compact size of 36. 8 mm × 24. 0 mm,a very low insertion loss of less than 0. 7 dB under 1. 9 GHz,and a wide SB from 2. 2 GHz to 8 GHz with rejection of larger than 30 dB. | Han Yunan Yuan Siyu Sun Xiaoyu Mei Chaofan | 2018 | The Journal of China Universities of Posts and Telecommunications2018，25，3： | 1 |

| 13 | Growth and micromagnetic simulation of magnetite nanoparticles显示文摘Magnetite nanoparticles with different sizes and different assemblies were synthesized via hydrothermal method.Micromagnetic simulation shows the magnetite nanocubes with different sizes have different energy states,which determines the assembly mode.Magnetite nanocubes with the side length of 30-60 nm tended to be dispersed while both nanochains and dispersed nanoparticles were found to grow for the nanocubes with the side length less than 30 nm,which can be explained in the fact that the above two assembly modes have very close energies.The assembly mode of nanocubes with the size bigger than 60 nm is generally nanorings consisting of connected inter-grown nanocubes and the nanocubes are no longer single domain.The simulations are consistent with the experimental results. | ZHAO SuFen SUN Qian WANG RongMing HAN YuNan | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，7： | 1 |

| 16 | Interactions of phenol and benzaldehyde in electrocatalytic upgrading process显示文摘Biomass pyrolysis oil can be improved effectively by electrocatalytic hydrogenation(ECH).However,the unclear interactions among different components lead to low bio-oil upgrading efficiency in the conversion process.Herein,benzaldehyde and phenol,as common compounds in bio-oil,were chosen as model compounds.The interactions between the two components were explored in the ECH process by combining experiments and theoretical calculations.Results showed that phenol could accelerate the conversion of benzaldehyde in the ECH.The selectivity of benzyl alcohol was increased from 60.9%of unadded phenol to 99.1%with 30 mmol/L phenol concentration at 5 h.Benzaldehyde inhibited the ECH of phenol.In the presence of benzaldehyde,the conversion rate of phenol was below 10.0%with no cyclohexanone and cyclohexanol formation at 5 h.The density functional theory(DFT)calculations revealed that the phenol could promote the adsorption of benzaldehyde and facilitate the targeted conversion of benzaldehyde on the active site by lowering the reaction energy barrier.The research on the interaction between phenol and benzaldehyde in the ECH provides a theoretical basis for the application of ECH in practical bio-oil upgrading. | Lan Liang Chuanbin Wang Xukai Lu Yunan Sun Beibei Yan Ning Li Guanyi Chen Li'an Hou | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 17 | A method of convolutional neural network based on frequency segmentation for monitoring the state of wind turbine blades显示文摘Wind turbine blades are prone to failure due to high tip speed,rain,dust and so on.A surface condition detecting approach based on wind turbine blade aerodynamic noise is proposed.On the experimental measurement data,variational mode decomposition filtering and Mel spectrogram drawing are conducted first.The Mel spectrogram is divided into two halves based on frequency characteristics and then sent into the convolutional neural network.Gaussian white noise is superimposed on the original signal and the output results are assessed based on score coefficients,considering the complexity of the real environment.The surfaces of Wind turbine blades are classified into four types:standard,attachments,polishing,and serrated trailing edge.The proposed method is evaluated and the detection accuracy in complicated background conditions is found to be 99.59%.In addition to support the differentiation of trained models,utilizing proper score coefficients also permit the screening of unknown types. | Weijun Zhu Yunan Wu Zhenye Sun Wenzhong Shen Guangxing Guo Jianwei Lin | 2023 | Theoretical & Applied Mechanics Letters2023，13，6： | 0 |
