| 1 | Fast structured illumination microscopy via deep learning显示文摘This study shows that convolutional neural networks(CNNs)can be used to improve the performance of structured illumination microscopy to enable it to reconstruct a super-resolution image using three instead of nine raw frames,which is the standard number of frames required to this end.Owing to the isotropy of the fluorescence group,the correlation between the high-frequency information in each direction of the spectrum is obtained by training the CNNs.A high-precision super-resolution image can thus be reconstructed using accurate data from three image frames in one direction.This allows for gentler super-resolution imaging at higher speeds and weakens phototoxicity in the imaging process. | CHANG LING CHONGLEI ZHANG MINGQUN WANG FANFEI MENG LUPING DU XIAOCONG YUAN | 2020 | Photonics Research2020，8，8： | 8 |
| 2 | SLIPS-TENG: robust triboelectric nanogenerator with optical and charge transparency using a slippery interface显示文摘Energy harvesting devices that prosper in harsh environments are highly demanded in a wide range of applications ranging from wearable and biomedical devices to self-powered and intelligent systems.Particularly,over the past several years,the innovation of triboelectric nanogenerators(TENGs)that efficiently convert ambient kinetic energy of water droplets or wave power to electricity has received growing attention.One of the main bottlenecks for the practical implications of such devices originates from the fast degradation of the physiochemical properties of interfacial materials under harsh environments.To overcome these challenges,here we report the design of a novel slippery lubricant-impregnated porous surface(SLIPS)based TENG,referred to as SLIPS-TENG,which exhibits many distinctive advantages over conventional design including optical transparency,configurability,self-cleaning,flexibility,and power generation stability,in a wide range of working environments.Unexpectedly,the slippery and configurable lubricant layer not only serves as a unique substrate for liquid/droplet transport and optical transmission,but also for efficient charge transfer.Moreover,we show that there exists a critical thickness in the liquid layer,below which the triboelectric effect is almost identical to that without the presence of such a liquid film.Such an intriguing charge transparency behavior is reminiscent of the wetting transparency and van der Waals potential transparency of graphene previously reported,though the fundamental mechanism remains to be elucidated.We envision that the marriage of these two seemingly totally different arenas(SLIPS and TENG)provides a paradigm shift in the design of robust and versatile energy devices that can be used as a clean and longer-lifetime alternative in various working environments. | Wanghuai Xu Xiaofeng Zhou Chonglei Hao Huanxi Zheng Yuan Liu Xiantong Yan Zhengbao Yang Michael Leung Xiao Cheng Zeng Ronald X.

| 3 | Dynamic full-color digital holographic 3D display on single DMD显示文摘Digital holography has high potentials for future 3D imaging and display technology.We present a method for a dynamic full-color digital holographic 3D display on single digital micro-mirror device(DMD)with full-color,high-speed and high-fidelity characteristics.We combine the square regions of adjacent micro-mirrors into super-pixels that can modulate amplitude and phase independently.Gray images are achieved by amplitude modulation and precise positioning of each color is achieved by phase modulation.The proposed method realizes a full-color imaging based on the three primary colors and achieves measured structural similarity of more than 88%and color similarity of more than 98%,while retaining the high switch speed of 9 kHz,thus achieving dynamic full-color 3D display on charge-coupled device(CCD). | Chonglei Zhang Dongfang Zhang Zhouping Bian | 2021 | Opto-Electronic Advances2021，4，3： | 6 |

| 5 | Nature-inspired surface topography: design and function显示文摘Learning from nature has traditionally and continuously provided important insights to drive a paradigm shift in technology.In particular,recent studies show that many biological organisms exhibit spectacular surface topography such as shape,size,spatial organization,periodicity,interconnectivity,and hierarchy to endow them with the capability to adapt dynamically and responsively to a wide range of environments.More excitingly,in a broader perspective,these normally neglected topological features have the potential to fundamentally change the way of how engineering surface works,such as how fluid flows,how heat is transported,and how energy is generated,saved,and converted,to name a few.Thus,the design of nature-inspired surface topography for unique functions will spur new thinking and provide paradigm shift in the development of the new engineering surfaces.In this review,we first present a brief introduction to some insights extracted from nature.Then,we highlight recent progress in designing new surface topographies and demonstrate their applications in emerging areas including thermal-fluid transport,anti-icing,water harvesting,power generation,adhesive control,and soft robotics.Finally,we offer our perspectives on this emerging field,with the aim to stimulate new thinking on the development of next-generation of new materials and devices,and dramatically extend the boundaries of traditional engineering. | XianTong Yan YuanKai Jin XueMei Chen Chao Zhang ChongLei Hao ZuanKai Wang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，2： | 3 |
| 6 | Multipath structure of the typical under-ice sound channel in the Arctic:theory and experiment显示文摘Considering the typical acoustic environment of the Arctic, this paper proposes a method based on OASES-Bellhop coupled model to rapidly analyze the multipath structure of the under-ice sound channel. Firstly the proposed model refers to ice plate as stratified elastic media with some roughness. Secondly,it uses the perturbation method and Kirchhoff approximation theory to solve the scattering loss due to the sea ice inhomogeneity. Finally, the model predicts the multipath structure of the under-ice channel through Ray theory. The results of the numerical simulation and experiment indicate that the typical Arctic sound channel presents multipath structures due to the sea ice and seabed in the range of 6 km, respectively.The sea ice reflection paths are stable,with a short multipath spread within 14 ms. The seabed reflection paths have relatively weak strength. The proposed OASES-Bellhop coupled model successfully predicts the amplitude and delay of the multipath structure with small error,which indicates the proposed model is able to analyze and predict the multipath structure of the observed acoustic environment in experiment. | LIU Chonglei HUANG Haining YIN Li LIU Na WEI Chonghua LI Qihu | 2019 | Chinese Journal of Acoustics2019，38，1： | 3 |

| 12 | Rotating Surfaces Promote the Shedding of Droplets显示文摘Achieving rapid shedding of droplets from solid surfaces has received substantial attention because of its diverse applications.Previous studies have focused on minimizing contact times of liquid droplets interacting with stationary surfaces,yet little consideration has been given to that of moving surfaces.Here,we report a different scenario:A water droplet rapidly detaches from micro/nanotextured rotating surfaces in an intriguing doughnut shape,contributing to about 40%contact time reduction compared with that on stationary surfaces.The doughnut-shaped bouncing droplet fragments into satellites and spontaneously scatters,thus avoiding further collision with the substrate.In particular,the contact time is highly dependent on impact velocities of droplets,beyond previous descriptions of classical inertialcapillary scaling law.Our results not only deepen the fundamental understanding of droplet dynamics on moving surfaces but also suggest a synergistic mechanism to actively regulate the contact time by coupling the kinematics of droplet impingement and surface rotation. | Ran Tao Wei Fang Jun Wu Binhong Dou Wanghuai Xu Zhanying Zheng Bing Li Zuankai Wang Xiqiao Feng Chonglei Hao | 2023 | Research2023，，1： | 0 |
| 13 | Particle breakage of sand subjected to friction and collision in drum tests显示文摘This paper presents a laboratory experimental study on particle breakage of sand subjected to friction and collision,by a number of drum tests on granular materials(silica sand No.3 and ceramic balls)to investigate the characteristics of particle breakage and its effect on the characteristics of grain size distribution of sand.Particle breakage increased in up convexity with increasing duration of drum tests,but increased linearly with increasing number of balls.Particle breakage showed an increase,followed by a decrease while increasing the amount of sand.There may be existence of a characteristic amount of sand causing a maximum particle breakage.Friction tests caused much less particle breakage than collision tests did.Friction and collision resulted in different mechanisms of particle breakage,mainly by abrasion for friction and by splitting for collision.The fines content increased with increasing relative breakage.Particle breakage in the friction tests(abrasion)resulted in a sharper increase but with a smaller total amount of fines content in comparison with that in the collision tests(splitting).For the collision tests,the fines content showed a decrease followed by an increase as the amount of sand increased,whereas it increased in up convexity with increasing number of balls.The characteristic grain sizes D_(10) and D_(30) decreased in down convexity with increasing relative breakage,which could be described by a natural exponential function.However,the characteristic grain sizes D50 and D60 decreased linearly while increasing the relative breakage.In addition,the coefficients of uniformity and curvature of sand showed an increase followed by a decrease while increasing the relative breakage. | Fangwei Yu Chonglei Zhang Qijun Xie Lijun Su Tao Zhao M.Qasim Jan | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，2： | 0 |
| 14 | A Brief Review of Design and Simulation Methodology in Silicon Photonics显示文摘Powerful electronic design automation tools have enabled the rapid development of electronic Integrated Circuits(ICs). Similar to electronic ICs, silicon photonics technology has sufficiently matured, and large-scale photonic circuits can now be implanted into a single chip. Design tools have also evolved from primary devices to complex photonic circuits. In this paper, we review the current state of photonic design automation in terms of device modeling methods and circuit simulation methodologies, and compare the photonics design flow with mature electronic design automation design flows. Key challenges and opportunities are also discussed. | Chonglei Sun Liuge Du Jia Zhao | 2022 | Tsinghua Science and Technology2022，27，3： | 0 |
| 15 | Temporal compressive super-resolution microscopy at frame rate of 1200 frames per second and spatial resolution of 100 nm显示文摘Various super-resolution microscopy techniques have been presented to explore fine structures of biological specimens.However,the super-resolution capability is often achieved at the expense of reducing imaging speed by either point scanning or multiframe computation.The contradiction between spatial resolution and imaging speed seriously hampers the observation of high-speed dynamics of fine structures.To overcome this contradiction,here we propose and demonstrate a temporal compressive super-resolution microscopy(TCSRM)technique.This technique is to merge an enhanced temporal compressive microscopy and a deep-learning-based super-resolution image reconstruction,where the enhanced temporal compressive microscopy is utilized to improve the imaging speed,and the deep-learning-based super-resolution image reconstruction is used to realize the resolution enhancement.The high-speed super-resolution imaging ability of TCSRM with a frame rate of 1200 frames per second(fps)and spatial resolution of 100 nm is experimentally demonstrated by capturing the flowing fluorescent beads in microfluidic chip.Given the outstanding imaging performance with high-speed super-resolution,TCSRM provides a desired tool for the studies of high-speed dynamical behaviors in fine structures,especially in the biomedical field. | Yilin He Yunhua Yao Dalong Qi Yu He Zhengqi Huang Pengpeng Ding Chengzhi Jin Chonglei Zhang Lianzhong Deng Kebin Shi Zhenrong Sun Xiaocong Yuan Shian Zhang | 2023 | Advanced Photonics2023，5，2： | 0 |
| 16 | Ultrasonic signal detection based on Fabry–Perot cavity sensor显示文摘Acoustic/ultrasonic sensors are devices that can convert mechanical energy into electrical signals.The Fabry–Perot cavity is processed on the end face of the double-clad fiber by a two-photon three-dimensional lithography machine.In this study,the outer diameter of the core cladding was 250μm,the diameter of the core was 9μm,and the microcavity sensing unit was only 30μm.It could measure ultrasonic signals with high precision.The characteristics of the proposed ultrasonic sensor were investigated,and its feasibility was proven through experiments.Its design has a small size and can replace a larger ultrasonic detector device for photoacoustic signal detection.The sensor is applicable to the field of biomedical information technology,including medical diagnosis,photoacoustic endoscopy,and photoacoustic imaging. | Wu Yang Chonglei Zhang Jiaqi Zeng Wei Song | 2021 | Visual Computing for Industry,Biomedicine,and Art2021，4，1： | 0 |
