1Foveated glasses-free 3D display with ultrawide field of view via a large-scale 2D-metagrating complex显示文摘Glasses-free three-dimensional(3D)displays are one of the game-changing technologies that will redefine the display industry in portable electronic devices.However,because of the limited resolution in state-of-the-art display panels,current 3D displays suffer from a critical trade-off among the spatial resolution,angular resolution,and viewing angle.Inspired by the so-called spatially variant resolution imaging found in vertebrate eyes,we propose 3D display with spatially variant information density.Stereoscopic experiences with smooth motion parallax are maintained at the central view,while the viewing angle is enlarged at the periphery view.It is enabled by a large-scale 2D-metagrating complex to manipulate dot/linear/rectangular hybrid shaped views.Furthermore,a video rate full-color 3D display with an unprecedented 160°horizontal viewing angle is demonstrated.With thin and light form factors,the proposed 3D system can be integrated with off-the-shelf purchased flat panels,making it promising for applications in portable electronics.Jianyu Hua Erkai Hua Fengbin Zhou Jiacheng Shi Chinhua Wang Huigao Duan Yueqiang Hu Wen Qiao Linsen Chen 2021Light(Science & Applications)2021,10,11:14
2Identification of immunoreactive proteins of Brucella melitensis by immunoproteomics显示文摘Infection with Brucella causes brucellosis, a chronic disease in humans, which induces abortion and sterility in livestock. Among the different Brucella species, Brucella melitensis is considered the most virulent and is the predominant species associated with outbreaks in China. To date, no safe human vaccine is available against Brucella infection. The currently used live vaccines against Brucella in livestock induce antibodies that interfere with the diagnosis of field infection in vaccinated animals, which is harmful to eradication programs. However, there is as yet no complete profile of immunogenic proteins of B. melitensis. Towards the development of a safer, equally efficacious, and field infection-distinguishable vaccine, we used immunoproteomics to identify novel candidate immunogenic proteins from B. melitensis M5. Eighty-eight immunoreactive protein spots from B. melitensis M5 were identified by Western blotting and were assigned to sixty-one proteins by mass spectrometry, including many new immunoreactive proteins such as elongation factor G, F0F1 ATP synthase subunit beta, and OMP1. These provide many candidate immunoreactive proteins for vaccine development.ZHAO ZhongPeng YAN Fang JI WenHui LUO DeYan LIU Xin XING Li DUAN YueQiang YANG PengHui SHI XiuMin LI Zhong WANG XiLiang 2011Science China(Life Sciences)2011,54,9:12
33D-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 2019Light(Science & Applications)2019,8,1:6
4Metasurface-enabled on-chip multiplexed diffractive neural networks in the visible显示文摘Replacing electrons with photons is a compelling route toward high-speed,massively parallel,and low-power artificial intelligence computing.Recently,diffractive networks composed of phase surfaces were trained to perform machine learning tasks through linear optical transformations.However,the existing architectures often comprise bulky components and,most critically,they cannot mimic the human brain for multitasking.Here,we demonstrate a multi-skilled diffractive neural network based on a metasurface device,which can perform on-chip multi-channel sensing and multitasking in the visible.The polarization multiplexing scheme of the subwavelength nanostructures is applied to construct a multi-channel classifier framework for simultaneous recognition of digital and fashionable items.The areal density of the artificial neurons can reach up to 6.25×10^(6)mm^(-2) multiplied by the number of channels.The metasurface is integrated with the mature complementary metal-oxide semiconductor imaging sensor,providing a chip-scale architecture to process information directly at physical layers for energy-efficient and ultra-fast image processing in machine vision,autonomous driving,and precision medicine.Xuhao Luo Yueqiang Hu Xiangnian Ou Xin Li Jiajie Lai Na Liu Xinbin Cheng Anlian Pan Huigao Duan 2022Light(Science & Applications)2022,11,7:4
5Dielectric metalens for miniaturized imaging systems:progress and challenges显示文摘Lightweight, miniaturized optical imaging systems are vastly anticipated in these fields of aerospace exploration, industrial vision, consumer electronics, and medical imaging. However, conventional optical techniques are intricate to downscale as refractive lenses mostly rely on phase accumulation. Metalens, composed of subwavelength nanostructures that locally control light waves, offers a disruptive path for small-scale imaging systems. Recent advances in the design and nanofabrication of dielectric metalenses have led to some high-performance practical optical systems. This review outlines the exciting developments in the aforementioned area whilst highlighting the challenges of using dielectric metalenses to replace conventional optics in miniature optical systems. After a brief introduction to the fundamental physics of dielectric metalenses, the progress and challenges in terms of the typical performances are introduced. The supplementary discussion on the common challenges hindering further development is also presented, including the limitations of the conventional design methods, difficulties in scaling up, and device integration. Furthermore, the potential approaches to address the existing challenges are also deliberated.Meiyan Pan Yifei Fu Mengjie Zheng Hao Chen Yujia Zang Huigao Duan Qiang Li Min Qiu Yueqiang Hu 2022Light(Science & Applications)2022,11,8:3
6Basic fibroblast growth factor protects against influenza A virus-induced acute lung injury by recruiting neutrophils显示文摘Influenza virus (IAV)infection is a major cause of severe respiratory illness that affects almost every country in the world.IAV infections result in respiratory illness and even acute lung injury and death,but the underlying mechanisms responsible for IAV pathogenesis have not yet been fully elucidated.In this study,the basic fibroblast growth factor 2 (FGF2)level was markedly increased in H1N1 virus-infected humans and mice.FGF2,which is predominately derived from epithelial cells,recruits and activates neutrophils via the FGFR2-PI3K-AKT-NFKB signaling pathway.FGF2 depletion or knockout exacerbated influenzaassociated disease by impairing neutrophil recruitment and activation.More importantly,administration of the recombinant FGF2 protein significantly aUeviated the severity of IAV-induced lung injury and promoted the survival of IAV-infected mice.Based on the results from experiments in which neutrophils were depleted and adoptively transferred,FGF2 protected mice against IAV , infection by recruiting neutrophils.Thus,FGF2 plays a critical role in preventing IAV-induced lung injury,and FGF2 is a promising potential therapeutic target during IAV infection.Keyu Wang Chengcai Lai Tieling Li Cheng Wang Wei Wang Bing Ni Changqing Bai Shaogeng Zhang Lina Han Hongjing Gu Zhongpeng Zhao Yueqiang Duan Xiaolan Yang Li Xing Lingna Zhao Shanshan Zhou Min Xia Chengyu Jiang Xiliang Wang Penghui Yang 2018Journal of Molecular Cell Biology2018,10,6:3
7Accurate inverse design of Fabry–Perot-cavity-based color filters far beyond sRGB via a bidirectional artificial neural network显示文摘Structural color based on Fabry–Perot(F-P) cavity enables a wide color gamut with high resolution at submicroscopic scale by varying its geometrical parameters. The ability to design such parameters that can accurately display the desired color is therefore crucial to the manufacturing of F-P cavities for practical applications.This work reports the first inverse design of F-P cavity structure using deep learning through a bidirectional artificial neural network. It enables the production of a significantly wider coverage of color space that is over 215% of sRGB with extremely high accuracy, represented by an average ΔE_(2000) value below 1.2. The superior performance of this structural color-based neural network is directly ascribed to the definition of loss function in the uniform CIE 1976-Lab color space. Over 100,000 times improvement in the design efficiency has been demonstrated by comparing the neural network to the metaheuristic optimization technique using an evolutionary algorithm when designing the famous painting of 'Haystacks, end of Summer' by Claude Monet. Our results demonstrate that, with the correct selection of loss function, deep learning can be very powerful to achieve extremely accurate design of nanostructured color filters with very high efficiency.PENG DAI YASI WANG YUEQIANG HU C.H.DE GROOT OTTO MUSKENS HUIGAO DUAN RUOMENG HUANG 2021Photonics Research2021,9,5:2
8Platelet carbon nanofibers as support of Pt-CoO electrocatalyst for superior hydrogen evolution显示文摘Exploration of cost-effective Pt/C catalysts has been a significant issue for electrochemical hydrogen evolution reaction(HER) toward sustainable energy conversion and storage.Herein,we report a fabrication strategy by employing platelet carbon nanofibers(p-CNF) as the support to immobilize Pt-CoO HER electrocatalyst using atomic layer deposition method.The edge-rich p-CNF support is found to act as the anchoring sites of Pt nanoparticles and favorably capture electrons from Pt to yield electron-deficient Pt surfaces for the boosted HER.Additionally,the sequential growth of CoO onto the Pt/p-CNF catalyst elaborately constructs the Pt-CoO interface and facilitates the electron transfer from Pt to CoO,which further enhances the HER activity.These advantages endow the fabricated Pt-CoO/p-CNF catalyst with the superior HER activity,e.g.,a very low overpotential of 26 mV at the current density of 10 mA·cm-2 and a mass activity of 4.42 A·mgPt-1at the overpotential of 30 mV,18.8 times higher than that of the commercial20 wt% Pt/C catalyst.The insights reported here could shed light on for the fabrication of cost-effective Pt-based composite HER catalysts.Jie Gan Zikun Huang Wei Luo Wenyao Chen Yueqiang Cao Gang Qian Xinggui Zhou Xuezhi Duan 2021Journal of Energy Chemistry2021,30,1:1
9Angular momentum holography via a minimalist metasurface for optical nested encryption显示文摘Metasurfaces can perform high-performance multi-functional integration by manipulating the abundant physical dimensions of light,demonstrating great potential in high-capacity information technologies.The orbital angular momentum(OAM)and spin angular momentum(SAM)dimensions have been respectively explored as the independent carrier for information multiplexing.However,fully managing these two intrinsic properties in information multiplexing remains elusive.Here,we propose the concept of angular momentum(AM)holography which can fully synergize these two fundamental dimensions to act as the information carrier,via a single-layer,non-interleaved metasurface.The underlying mechanism relies on independently controlling the two spin eigenstates and arbitrary overlaying them in each operation channel,thereby spatially modulating the resulting waveform at will.As a proof of concept,we demonstrate an AM meta-hologram allowing the reconstruction of two sets of holographic images,i.e.,the spin-orbital locked and the spin-superimposed ones.Remarkably,leveraging the designed dual-functional AM meta-hologram,we demonstrate a novel optical nested encryption scheme,which is able to achieve parallel information transmission with ultra-high capacity and security.Our work opens a new avenue for optionally manipulating the AM,holding promising applications in the fields of optical communication,information security and quantum science.Hui Yang Peng He Kai Ou Yueqiang Hu Yuting Jiang Xiangnian Ou Honghui Jia Zhenwei Xie Xiaocong Yuan Huigao Duan 2023Light(Science & Applications)2023,12,4:1

11Mechanistic aspects of facet-dependent CH_(4)/C_(2+)selectivity over aχ-Fe_(5)C_(2)Fischer-Tropsch catalyst显示文摘Structure-performance relationship is a complex issue in iron-catalyzed Fischer-Tropsch synthesis,and it is not easy to elucidate it by experimental investigations.First-principle calculation is a powerful method for explaining experimental results and guiding catalyst design.In this study,we investigated the reaction mechanisms of CH_(4)formation and C-C coupling on fourχ-Fe_(5)C_(2)surfaces and established the kinetic equations to compare the rates of CH_(4)formation and C_(1)+C_(1)coupling reactions and determine the CH_(4)/C_(2+)selectivity.The results show that the geometry of theχ-Fe_(5)C_(2)surfaces has little effect on the formation rate of CH_(4);however,the C_(1)+C_(1)coupling reactions are significantly affected by the surface geometry.The C_(1)+C_(1)coupling reaction rates on the terraced-like(510)and(021)surfaces are much higher than those on the stepped-like(001)and(100)surfaces.Based on these results,we established a Brùnsted-Evans-Polanyi(BEP)relationship between the effective barrier difference for CH_(4)formation and C_(1)+C_(1)coupling(ΔE_(eff))and the adsorption energy of C+4H(ΔE_(C+4H))onχ-Fe_(5)C_(2)surfaces.ΔE_(C+4H)can be used as a descriptor for CH_(4)/C_(2+)selectivity on different surfaces ofχ-Fe_(5)C_(2).Thanh Hai Pham Junbo Cao Nan Song Yueqiang Cao Bingxu Chen Gang Qian Xinggui Zhou De Chen Xuezhi Duan 2022Green Energy & Environment2022,7,3:1

13Active sites and reaction mechanism for N-doped carbocatalysis of phenol removal显示文摘Heteroatom-doping of carbocatalysts has been a powerful strategy to remarkably enhance the catalytic performance.Herein,the underlying nature of N promotional effects on peroxymonosulfate(PMS)activation for phenol removal is understood by combining kinetics analysis with multiple techniques.A strategy using mixed acid oxidation of carbon nanotube(CNT)followed by NH3 treatment is employed to yield a series of catalysts with different N-doping contents but similar fraction of sp^(2)-hybridized carbon and defective degree,endowing with a chance to discriminate the dominant N-containing active sites.The multi-sites kinetics analysis suggests the graphitic N-containing sites as the dominant active sites.The mechanism of the surface-bound reactive species is also discriminated as the dominant reaction mechanism.The insights reported here could provide the methodology to fundamentally understand the heteroatom-doping effects of carbocatalysis.Mingjie Zhang Chen Han Wenyao Chen Wei Luo Yueqiang Cao Gang Qian Xinggui Zhou Xiaoguang Duan Shaobin Wang Xuezhi Duan 2020Green Energy & Environment2020,5,4:1

15High-Speed Parallel Plasmonic Direct-Writing Nanolithography Using Metasurface-Based Plasmonic Lens显示文摘Simple and efficient nanofabrication technology with low cost and high flexibility is indispensable for fundamental nanoscale research and prototyping.Lithography in the near field using the surface plasmon polariton(i.e.,plasmonic lithography)provides a promising solution.The system with high stiffness passive nanogap control strategy on a high-speed rotating substrate is one of the most attractive highthroughput methods.However,a smaller and steadier plasmonic nanogap,new scheme of plasmonic lens,and parallel processing should be explored to achieve a new generation high resolution and reliable efficient nanofabrication.Herein,a parallel plasmonic direct-writing nanolithography system is established in which a novel plasmonic flying head is systematically designed to achieve around 15 nm minimum flying-height with high parallelism at the rotating speed of 8–18 m·s^(-1).A multi-stage metasurface-based polarization insensitive plasmonic lens is proposed to couple more power and realize a more confined spot compared with conventional plasmonic lenses.Parallel lithography of the nanostructures with the smallest(around 26 nm)linewidth is obtained with the prototyping system.The proposed system holds great potential for high-freedom nanofabrication with low cost,such as planar optical elements and nano-electromechanical systems.Yueqiang Hu Ling Li Rong Wang Jian Song Hongdong Wang Huigao Duan Jiaxin Ji Yonggang Meng 2021Engineering2021,7,11:0
16Structural and Kinetics Understanding of Support Effects in Pd-Catalyzed Semi-Hydrogenation of Acetylene显示文摘In this study,the support effects on the Pd-catalyzed semi-hydrogenation of acetylene have been investigated from the structural and kinetic perspectives.According to the results of kinetic analysis and X-ray photoelectron spectroscopy,hydrogen temperature-programmed reduction,temperature-programmed hydride decomposition,and in situ X-ray diffraction measurements,using carbon nanotubes as support for Pd nanocatalysts with various sizes instead of a-Al_(2)O_(3) decreases the Pd^(0)3d binding energy and suppresses the formation of undesirable palladium hydride species,thus increasing the ethylene yield.Furthermore,X-ray absorption spectroscopy,high-resolution transmission electron microscopy,and C_(2)H_(4) temperature-programmed desorption studies combined with density-functional theory calculations reveal the existence of a unique Pd local environment,containing subsurface carbon atoms,that produces positive geometric effects on the acetylene conversion reaction.Therefore,tailoring the Pd local environment and electronic properties represents an effective strategy for the fabrication and design of highly active and selective Pd semi-hydrogenation catalysts.Yueqiang Cao Xiaohu Ge Yurou Li Rui Si Zhijun Sui Jinghong Zhou Xuezhi Duan Xinggui Zhou 2021Engineering2021,7,1:0
17Enhanced recycling performance of bimetallic Ir-Re/SiO_(2) catalyst by amberlyst-15 for glycerol hydrogenolysis显示文摘Recycling performance of heterogeneous catalysts is of crucial importance especially for a batch reaction system.In this work,we demonstrate a strategy for enhancing recycling performance of Ir-Re/SiO_(2) catalyst synergized with amberlyst-15 in glycerol hydrogenolysis to produce 1,3-propanediol.Comprehensive characterization results reveal that the Re sites in the Ir-Re/SiO_(2) catalyst undergo irreversible segregation and oxidation.These hinder the formation of active ReAOH species and thus contribute to a complete and irreversible deactivation.However,the introduction of amberlyst-15 into the reactant mixture can restrain the oxidation process of Re sites and favor the formation of ReAOH species,and thus significantly enhance the catalytic recycling performance.The results demonstrated here could guide the development of excellent bimetallic catalysts with the desirable recycling performances for the reaction.Xin Ren Li Leng Yueqiang Cao Jing Zhang Xuezhi Duan Xueqing Gong Jinghong Zhou Xinggui Zhou 2022Chinese Journal of Chemical Engineering2022,35,5:0

19Unleash electron transfer in C–H functionalization by mesoporous carbon-supported palladium interstitial catalysts显示文摘The functionalization of otherwise unreactive C–H bonds adds a new dimension to synthetic chemistry,yielding useful molecules for a range of applications.Arylation has emerged as an increasingly viable strategy for functionalization of heteroarenes which constitute an important class of structural moieties for organic materials.However,direct bisarylation of heteroarenes to enable aryl-heteroaryl-aryl bond formation remains a formidable challenge,due to the strong coordination between heteroatom of N or S and transitional metals.Here we report Pd interstitial nanocatalysts supported on ordered mesoporous carbon as catalysts for a direct and highly efficient bisarylation method for five-membered heteroarenes that allows for green and mild reaction conditions.Notably,in the absence of any base,ligands and phase transfer agents,high activity(turn-over frequency,TOF,up to 107 h-1)and selectivity(>99%)for the 2,5-bisarylation of five-membered heteroarenes are achieved in water.A combination of characterization reveals that the remarkable catalytic reactivity here is attributable to the parallel adsorption of heteroarene over Pd clusters,which breaks the barrier to electron transfer in traditional homogenous catalysis and creates dual electrophilic sites for aryl radicals and adsorbate at C2 and C5 positions.The d-band filling at Pd sites shows a linear relationship with activation entropy and catalytic activity.The ordered mesopores facilitate the absence of a mass transfer effect.These findings suggest alternative synthesis pathways for the design,synthesis and understanding of a large number of organic chemicals by ordered mesoporous carbon supported palladium catalysts.Xiaorui Zhao Yueqiang Cao Linlin Duan Ruoou Yang Zheng Jiang Chao Tian Shangjun Chen Xuezhi Duan De Chen Ying Wan 2021National Science Review2021,8,4:0
20Mechanistic insights into the active intermediates of 2,6-diaminopyridine dinitration显示文摘Mechanistic understanding of the active intermediates of 2,6-diaminopyridine(DAP) dinitration in the concentrated nitric-sulfuric acid system is of crucial importance for the selectivity control of target product, i.e., 2,6-diamino-3,5-dinitropyridine(DADNP). The active intermediates determining the product selectivity are theoretically studied. The HSO_(4)^(-)-NO_(2)^(+) complex is proposed as the dominant active nitrating intermediate for the first time, which shows low energy barrier(i.e., 10.19 kcal·mol^(-1),1 kcal = 4.186 k J) for direct dinitration of DAP to DADNP. The formed water during the reaction results in not only the formation of less active SO_(4)^(2-)-NO_(2)^(+) complex, but also the occurance of DAP sulfonation(DAP-SO_(3)H intermediate)to facilitate the formation of mononitration byproduct. Meanwhile, the accompanied thermal effects cause the generation of undesirable pyridine-NHNO_(2) intermediate, which is difficult to be rearranged to yield DADNP, inhibiting the reaction and thus giving low DAP conversion. The insights reported here elucidates the importance of thermal effects elimination and water content control, confirmed experimentally in the batch-and micro-reaction systems.Junao Zhu Zhirong Yang Yuanhan Chen Mingming Chen Zhen Liu Yueqiang Cao Jing Zhang Gang Qian Xinggui Zhou Xuezhi Duan 2023Chinese Journal of Chemical Engineering2023,56,4:0
