| 1 | 3D-Integrated metasurfaces for full-colour holography显示文摘Metasurfaces enable the design of optical elements by engineering the wavefront of light at the subwavelength scale.Due to their ultrathin and compact characteristics,metasurfaces possess great potential to integrate multiple functions in optoelectronic systems for optical device miniaturisation.However,current research based on multiplexing in the 2D plane has not fully utilised the capabilities of metasurfaces for multi-tasking applications.Here,we demonstrate a 3D-integrated metasurface device by stacking a hologram metasurface on a monolithic Fabry–Pérot cavity-based colour filter microarray to simultaneously achieve low-crosstalk,polarisation-independent,high-efficiency,full-colour holography,and microprint.The dual functions of the device outline a novel scheme for data recording,security encryption,colour displays,and information processing.Our 3D integration concept can be extended to achieve multi-tasking flat optical systems by including a variety of functional metasurface layers,such as polarizers,metalenses,and others. | Yueqiang Hu Xuhao Luo Yiqin Chen Qing Liu Xin Li Yasi Wang Na Liu Huigao Duan | 2019 | Light(Science & Applications)2019，8，1： | 6 |

| 3 | Highway constructions on the Qinghai-Tibet Plateau:Challenge,research and practice显示文摘Highway constructions on the Qinghai-Tibet Plateau(QTP)face great challenges induced by the unique local environmental,geological,and engineering conditions.The large area of permafrost,great temperature variability,strong UV rays,and complex geological conditions are the major factors that adversely influence the longterm performance of pavement systems.Since 1960s,Chinese engineers and researchers have started conducting research on the QTP to enhance the performance and durability of pavement systems.The present paper provide a comprehensive review of challenge,research and practice of highway constructions on the QTP including the special environmental and geological conditions,history of highway constructions on the QTP,major challenges and the state-of-the-art technology of subgrade constructions on permafrost,developments of the pavement structures and materials,performance prediction and maintenance methods of pavement surfaces,and applications of the research achievements on the first expressway on the QTP(i.e.,Gongyu Expressway).Based on the comprehensive literature review,it can be found that(1)frost heave and thaw weakening induced subgrade disease and longitudinal cracks on the pavement surface are complex coupled water-thermal-load problems.Engineering solutions are focusing on active cooling and thermal insulation methods,which can help to reduce temperature variations in the subgrade and thus improving its stability,(2)the harsh environmental and construction conditions may reduce the early strength and induce premature damage of cement-treated base materials.Some field validations showed that geocell-reinforced or asphalt-treated flexible base materials can provide better long-term performance,(3)the large temperature variability and strong UV rays can significantly accelerate aging of asphalt binders and greatly reduce the service life of asphalt mixtures.Various binder modification methods were developed for improving their viscoelasticity and enhance the low-temperature cracking resistance of pavement surface materials but are still lack of field validation data and comparisons of their life cycle costs.Therefore,it is recommended that a demonstration research project build test sections to examine a range of pavement structures and materials,and compare their long-term performance and life cycle costs,which can serve as important reference for future highway constructions on the QTP. | Aimin Sha Biao Ma Hainian Wang Liqun Hu Xuesong Mao Xilan Zhi Huaxin Chen Yu Liu Feng Ma Zhuangzhuang Liu Rui He Wei Si Xuhao Wang Cheng Li | 2022 | Journal of Road Engineering2022，2，1： | 4 |
| 4 | Multi-foci metalens for spectra and polarization ellipticity recognition and reconstruction显示文摘Multispectral and polarized focusing and imaging are key functions that are vitally important for a broad range of optical applications.Conventional techniques generally require multiple shots to unveil desired optical information and are implemented via bulky multi-pass systems or mechanically moving parts that are difficult to integrate into compact and integrated optical systems.Here,a design of ultra-compact transversely dispersive metalens capable of both spectrum and polarization ellipticity recognition and reconstruction in just a single shot is demonstrated with both coherent and incoherent light.Our design is well suited for integrated and high-speed optical information analysis and can significantly reduce the size and weight of conventional devices while simplifying the process of collecting optical information,thereby promising for various applications,including machine vision,minimized spectrometers,material characterization,remote sensing,and other areas which require comprehensive optical analysis. | Hui Gao Xuhao Fan Yuxi Wang Yuncheng Liu Xinger Wang Ke Xu Leimin Deng Cheng Zeng Tingan Li Jinsong Xia Wei Xiong | 2023 | Opto-Electronic Science2023，2，3： | 3 |

| 8 | Mori fructus aqueous extracts attenuates liver injury by inhibiting ferroptosis via the Nrf2 pathway显示文摘Background Liver fibrosis and hepatocellular carcinogenesis secondary to liver fibrosis are serious liver diseases with no effective treatments.Mori fructus aqueous extracts(MFAEs)have served as successful treatments for many types of liver injury including fibrosis although the molecular mechanisms are unknown at present.Purpose To investigate the effect of MFAEs in alleviating acute and chronic liver injury and tried to decipher the underlying mechanism.Methods and results Mice were divided into 5 groups(n ps:contro=8)for acute(groups:control,0.3%CCl_(4),bifendate(BD),100 and 200 mg/kg MFAEs,7 d)and chronic(groul,10%CCl_(4),BD,100 and 200 mg/kg MFAEs,4 weeks)liver injury study.Each mouse was injected intraperitoneally with 10μL/g corn oil containing CCl_(4)expect the control group.HepG2 cells were used in vitro study.Eighteen communal components were identified by UPLC-LTQOrbitrap-MS.We utilized a mouse model for acute and chronic liver injury using CCl_(4)and MFAEs administration effectively blocked fibrosis and significantly inhibited inflammation in the liver.MFAEs activated the nuclear factor erythroid derived 2 like 2/heme oxygenase 1(Nrf2/HO-1)pathway and promoted the synthesis of the antioxidants glutathione(GSH),superoxidedismutase(SOD)and glutathione peroxidase(GSH-Px)that resulted in reduced levels of CCl_(4)-induced oxidative stress molecules including reactive oxygen species.These extracts administered to mice also inhibited ferroptosis in the liver by regulating the expression of Acyl-CoA synthetase long chain family member 4(ACSL4),solute carrier family 7 member 11(SLC7A11)and glutathione peroxidase 4(GPX4),thus reducing the occurrence of liver fibrosis.Both in vivo and in vitro tests indicated that the mechanism of MFAEs protection against liver fibrosis was linked to activation of Nrf2 signaling.These effects were blocked in vitro by the addition of a specific Nrf2 inhibitor.Conclusion MFAEs inhibited oxidative stress,ferroptosis and inflammation of the liver by activating Nrf2 signal pathway and provided a significant protective effect against CCl_(4)-induced liver fibrosis. | Yuanyuan Wei Chen Gao Huiru Wang Yannan Zhang Jinhua Gu Xiuying Zhang Xuhao Gong Zhihui Hao | 2023 | Journal of Animal Science and Biotechnology2023，14，4： | 1 |

| 10 | Digital Simulation of Projective Non-Abelian Anyons with 68 Superconducting Qubits显示文摘Non-Abelian anyons are exotic quasiparticle excitations hosted by certain topological phases of matter.They break the fermion-boson dichotomy and obey non-Abelian braiding statistics:their interchanges yield unitary operations,rather than merely a phase factor,in a space spanned by topologically degenerate wavefunctions.They are the building blocks of topological quantum computing.However,experimental observation of non-Abelian anyons and their characterizing braiding statistics is notoriously challenging and has remained elusive hitherto,in spite of various theoretical proposals.Here,we report an experimental quantum digital simulation of projective non-Abelian anyons and their braiding statistics with up to 68 programmable superconducting qubits arranged on a two-dimensional lattice.By implementing the ground states of the toric-code model with twists through quantum circuits,we demonstrate that twists exchange electric and magnetic charges and behave as a particular type of non-Abelian anyons,i.e.,the Ising anyons.In particular,we show experimentally that these twists follow the fusion rules and non-Abelian braiding statistics of the Ising type,and can be explored to encode topological logical qubits.Furthermore,we demonstrate how to implement both single-and two-qubit logic gates through applying a sequence of elementary Pauli gates on the underlying physical qubits.Our results demonstrate a versatile quantum digital approach for simulating non-Abelian anyons,offering a new lens into the study of such peculiar quasiparticles. | Shibo Xu Zheng-Zhi Sun Ke Wang Liang Xiang Zehang Bao Zitian Zhu Fanhao Shen Zixuan Song Pengfei Zhang Wenhui Ren Xu Zhang Hang Dong Jinfeng Deng Jiachen Chen Yaozu Wu Ziqi Tan Yu Gao Feitong Jin Xuhao Zhu Chuanyu Zhang Ning Wang Yiren Zou Jiarun Zhong Aosai Zhang Weikang Li Wenjie Jiang Li-Wei Yu Yunyan Yao Zhen Wang Hekang Li Qiujiang Guo Chao Song H.Wang Dong-Ling Deng | 2023 | Chinese Physics Letters2023，40，6： | 0 |

| 12 | Rational design of stretchable and conductive hydrogel binder for highly reversible SiP2 anode显示文摘The emerging SiP2with large capacity and suitable plateau is proposed to be the alternative anode for Li-ion batteries.However,typical SiP2still suffers from serious volume expansion and structural destruction,resulting in much Li-consumption and capacity fading.Herein,a novel stretchable and conductive Li-PAA@PEDOT:PSS binder is rationally designed to improve the cyclability and reversibility of SiP2.Interestingly,such Li-PAA@PEDOT:PSS hydrogel enables a better accommodation of volume expansion than PVDF binder(e.g.5.94% vs.68.73% of expansivity).More specially,the SiP2electrode with LiPAA@PEDOT:PSS binder is surprisingly found to enable unexpected structural recombination and selfhealing Li-storage processes,endowing itself with a high initial Coulombic efficiency(ICE) up to 93.8%,much higher than PVDF binder(ICE=70.7%) as well.Such unusual phenomena are investigated in detail for Li-PAA@PEDOT:PSS,and the possible mechanism shows that its Li-PAA component enables to prevent the pulverization of SiP2nanoparticles while the PEDOT:PSS greatly bridges fast electronic connection for the whole electrode.Consequently,after being further composited with carbon matrix,the SiP2/C with LiPAA@PEDOT:PSS hydrogel exhibits high reversibility(ICE> 93%),superior cyclability(>450 cycles),and rate capability(1520 mAh/g at 2000 mA/g) for LIBs.This highly stretchable and conductive binder design can be easily extended to other alloying materials toward advanced energy storage. | Xuhao Liu Runzhe Yao Siqi Wang Yaqing Wei Bin Chen Wei Liang Caiyun Tian Chengyu Nie De Li Yong Chen | 2023 | Journal of Energy Chemistry2023，，8： | 0 |

| 14 | Dynamic interactive bitwise meta-holography with ultra-high computational and display frame rates显示文摘Interactive holography offers unmatched levels of immersion and user engagement in the field of future display.Despite of the substantial progress has been made in dynamic meta-holography,the realization of real-time,highly smooth interactive holography remains a significant challenge due to the computational and display frame rate limitations.In this study,we introduced a dynamic interactive bitwise meta-holography with ultra-high computational and display frame rates.To our knowledge,this is the first reported practical dynamic interactive metasurface holographic system.We spa-tially divided the metasurface device into multiple distinct channels,each projecting a reconstructed sub-pattern.The switching states of these channels were mapped to bitwise operations on a set of bit values,which avoids complex holo-gram computations,enabling an ultra-high computational frame rate.Our approach achieves a computational frame rate of 800 kHz and a display frame rate of 23 kHz on a low-power Raspberry Pi computational platform.According to this methodology,we demonstrated an interactive dynamic holographic Tetris game system that allows interactive gameplay,color display,and on-the-fly hologram creation.Our technology presents an inspiration for advanced dynamic meta-holography,which is promising for a broad range of applications including advanced human-computer interaction,real-time 3D visualization,and next-generation virtual and augmented reality systems. | Yuncheng Liu Ke Xu Xuhao Fan Xinger Wang Xuan Yu Wei Xiong Hui Gao | 2024 | Opto-Electronic Advances2024，7，1： | 0 |
| 15 | SDDNet:Infrared small and dim target detection network显示文摘This study focuses on developing deep learning methods for small and dim target detection.We model infrared images as the union of the target region and background region.Based on this model,the target detection problem is considered a two‐class segmentation problem that divides an image into the target and background.Therefore,a neural network called SDDNet for single‐frame images is constructed.The network yields target extraction results according to the original images.For multiframe images,a network called IC‐SDDNet,a combination of SDDNet and an interframe correlation network module is constructed.SDDNet and IC‐SDDNet achieve target detection rates close to 1 on typical datasets with very low false positives,thereby performing significantly better than current methods.Both models can be executed end to end,so both are very convenient to use,and their implementation efficiency is very high.Average speeds of 540+/230+FPS and 170+/60+FPS are achieved with SDDNet and IC‐SDDNet on a single Tesla V100 graphics processing unit and a single Jetson TX2 embedded module respectively.Additionally,neither network needs to use future information,so both networks can be directly used in real‐time systems.The well‐trained models and codes used in this study are available at http://gffzz188fe103f8f1460asppknowbpp65n6cc0.ffgz.tsg.suse.edu.cn/LittlePieces/ObjectDetection. | Ma Long Shu Cong Huang Shanshan Wei Zoujian Wang Xuhao Wei Yanxi | 2023 | CAAI Transactions on Intelligence Technology2023，8，4： | 0 |
| 16 | Advances in high-performance MEMS pressure sensors:design,fabrication,and packaging显示文摘Pressure sensors play a vital role in aerospace,automotive,medical,and consumer electronics.Although microelectromechanical system(MEMS)-based pressure sensors have been widely used for decades,new trends in pressure sensors,including higher sensitivity,higher accuracy,better multifunctionality,smaller chip size,and smaller package size,have recently emerged.The demand for performance upgradation has led to breakthroughs in sensor materials,design,fabrication,and packaging methods,which have emerged frequently in recent decades.This paper reviews common new trends in MEMS pressure sensors,including minute differential pressure sensors(MDPSs),resonant pressure sensors(RPSs),integrated pressure sensors,miniaturized pressure chips,and leadless pressure sensors.To realize an extremely sensitive MDPS with broad application potential,including in medical ventilators and fire residual pressure monitors,the“beam-membrane-island”sensor design exhibits the best performance of 66μV/V/kPa with a natural frequency of 11.3 kHz.In high-accuracy applications,silicon and quartz RPS are analyzed,and both materials show±0.01%FS accuracy with respect to varying temperature coefficient of frequency(TCF)control methods.To improve MEMS sensor integration,different integrated“pressure+x”sensor designs and fabrication methods are compared.In this realm,the intercoupling effect still requires further investigation.Typical fabrication methods for microsized pressure sensor chips are also reviewed.To date,the chip thickness size can be controlled to be<0.1 mm,which is advantageous for implant sensors.Furthermore,a leadless pressure sensor was analyzed,offering an extremely small package size and harsh environmental compatibility.This review is structured as follows.The background of pressure sensors is first presented.Then,an in-depth introduction to MEMS pressure sensors based on different application scenarios is provided.Additionally,their respective characteristics and significant advancements are analyzed and summarized.Finally,development trends of MEMS pressure sensors in different fields are analyzed. | Xiangguang Han Mimi Huang Zutang Wu Yi Gao Yong Xia Ping Yang Shu Fan Xuhao Lu Xiaokai Yang Lin Liang Wenbi Su Lu Wang Zeyu Cui Yihe Zhao Zhikang Li Libo Zhao Zhuangde Jiang | 2023 | Microsystems & Nanoengineering2023，9，6： | 0 |
