| 1 | Controllable optical activity with non-chiral plasmonic metasurfaces显示文摘Optical activity is the rotation of the plane of linearly polarized light along the propagation direction as the light travels through optically active materials.In existing methods,the strength of the optical activity is determined by the chirality of the materials,which is difficult to control quantitatively.Here we numerically and experimentally investigated an alternative approach to realize and control the optical activity with non-chiral plasmonic metasurfaces.Through judicious design of the structural units of the metasurfaces,the right and left circular polarization components of the linearly polarized light have different phase retardations after transmitting through the metasurfaces,leading to large optical activity.Moreover,the strength of the optical activity can be easily and accurately tuned by directly adjusting the phase difference.The proposed approach based on non-chiral plasmonic metasurfaces exhibits large optical activity with a high controllable degree of freedom,which may provide more possibilities for applications in photonics. | Ping Yu Jianxiong Li Chengchun Tang Hua Cheng Zhaocheng Liu Zhancheng Li Zhe Liu Changzhi Gu Junjie Li Shuqi Chen Jianguo Tian | 2016 | Light(Science & Applications)2016，5，1： | 8 |
| 2 | The Influence of Extractable Organic Matter on Pore Development in the Late Triassic Chang 7 Lacustrine Shales, Yanchang Formation, Ordos Basin, China显示文摘To investigate the influence of extractable organic matter(EOM) on pore evolution of lacustrine shales, Soxhlet extraction, using dichloromethane, was performed on a series of Chang 7 shale samples(Ordos Basin, China) with vitrinite reflectance of 0.64% to 1.34%. Low-pressure gas adsorption experiments were conducted on the samples before and after extraction. The pore structure parameters were calculated from the gas adsorption data. The results show complex changes to the pore volumes and surface areas after extraction. The pore development of both the initial and extracted samples is strongly controlled by total organic carbon(TOC) content. Micropores developed mainly in organic matter(OM), while mesopores and macropores predominantly developed in fractions other than OM. The influence of EOM on micropores is stronger than on mesopores and macropores. Organic solvents with a higher boiling point should be used to explore the effect of EOM on pore structure in the future. | HAN Hui LIU Pengwei DING Zhengang SHI Pitong JIA Jianchao ZHANG Wei LIU Yan CHEN Shijia LU Jungang Chen Kang PENG Xudong WANG Zhiyong XIAO Shuqi GAO Yuans | 2018 | Acta Geologica Sinica(English Edition)2018，92，4： | 8 |
| 3 | Host metabolism dysregulation and cell tropism identification in human airway and alveolar organoids upon SARS-CoV-2 infection显示文摘The coronavirus disease 2019(COVID-19)pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which is spread primary via respiratory droplets and infects the lungs.Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines(transformed or cancer cells)and species differences between animals and humans.Organoids are stem cell-derived selforganized three-dimensional culture in vitro and model the physiological conditions of natural organs.Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells(hESCs)-derived lung organoids,including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs.The infected ceils were ciliated,club,and alveolar type 2(AT2)cells,which were sequentially located from the proximal to the distal airway and terminal alveoli,respectively.Additionally,RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes,especially lipid metabolism,in addition to the well-known upregulation of immune response.Further,Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids.Therefore,human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19. | Rongjuan Pei Jianqi Feng Yecheng Zhang Hao Sun Lian Li Xuejie Yang Jiangping He Shuqi Xiao Jin Xiong Ying Lin Kun Wen Hongwei Zhou Jiekai Chen Zhili Rong Xinwen Chen | 2021 | Protein & Cell2021，12，9： | 7 |
| 4 | In vitro effect of iASPP on cell growth of oral tongue squamous cell carcinoma显示文摘iASPP is an inhibitory member of the apoptosis-stimulating proteins of P53(ASPP) family. iASPP is over expressed in several malignant tumors and potentially affects cancer progression. However, the expression and potential role of iASPP in oral tongue squamous cell carcinoma(OTSCC) have not been addressed. In our study, we detected iASPP expression in OTSCC by immunohistochemistry. iASPP expression is up-regulated in OTSCC tissues. Moreover, in clinical pathology specimens, we found that increased iASPP expression correlates with poor differentiation and lymph node metastasis. Using multicellular tumor spheroids(MTS) and flow cytometry, we demonstrated that iASPP down-regulation arrests OTSCC cells at the G0/G1 phase, induces OTSCC cell apoptosis and inhibits OTSCC cell proliferation. These results indicate that iASPP plays a significant role in the progression of OTSCC and may serve as a biomarker or therapeutic target for OTSCC patients. | Yu Chen Wangxiang Yan Shuqi He Jiechun Chen Dan Chen Zhaoqiang Zhang Zhiguo Liu Xueqiang Ding Anxun Wang | 2014 | Chinese Journal of Cancer Research2014，26，4： | 7 |
| 5 | Multidimensional manipulation of wave fields based on artificial microstructures显示文摘Artificial microstructures,which allow us to control and change the properties of wave fields through changing the geometrical parameters and the arrangements of microstructures,have attracted plenty of attentions in the past few decades.Some artificial microstructure based research areas,such as metamaterials,metasurfaces and phononic topological insulators,have seen numerous novel applications and phenomena.The manipulation of different dimensions(phase,amplitude,frequency or polarization)of wave fields,particularly,can be easily achieved at subwavelength scales by metasurfaces.In this review,we focus on the recent developments of wave field manipulations based on artificial microstructures and classify some important applications from the viewpoint of different dimensional manipulations of wave fields.The development tendency of wave field manipulation from single-dimension to multidimensions provides a useful guide for researchers to realize miniaturized and integrated optical and acoustic devices. | Yuebian Zhang Hui Liu Hua Cheng Jianguo Tian Shuqi Chen | 2020 | Opto-Electronic Advances2020，3，11： | 7 |
| 6 | Control mechanism and technique of floor heave with reinforcing solid coal side and floor corner in gob-side coal entry retaining显示文摘Floor heave is the most common convergence in gob-side entry retaining.The paper analyzes the form,process and characteristics of gob-side entry retaining with the comprehensive methods of theoretical analysis,numerical simulation and the field trial.Research results present that bending and folding floor heave is the main factor in the stage of the first panel mining;squeezing and fluidity floor heave plays a great role in the stable stage of gob-side entry retaining;the combination of the former two factors affects mainly the stage of the second mining ahead;abutment pressure is a fundamental contribution to the serious floor heave of gob-side entry retaining,and sides corners of solid coal body are key part in the case of floor heave controlling of gob-side entry retaining.Floor heave of gob-side entry retaining can be significantly controlled by reinforcing sides and corners of solid coal body,and influence rules on the floor heave of gob side entry retaining of sides supporting strength and the bottom bolt orientation in solid coal side are obtained.Research results have been successfully applied in gob-side entry retaining of G20-F23070 face haulage roadway in #2 coal mine of Pingmei Group,and the field observation shows that the proposed technique is an effective way in controlling the floor heave of gob-side entry retaining. | Chen Yong Bai Jianbiao Yan Shuai Xu Ying Wang Xiangyu Ma Shuqi | 2012 | International Journal of Mining Science and Technology2012，22，6： | 6 |
| 7 | Naringenin is a Potential Immunomodulator for Inhibiting Liver Fibrosis by Inhibiting the cGAS-STING Pathway显示文摘Background and Aims:Naringenin is an anti-inflammatory flavonoid that has been studied in chronic liver disease.The mechanism specific to its antifibrosis activity needs further investigation This study was to focused on the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)pathway in hepatic stellate cells and clarified the antifibrosis mechanism of naringenin.Methods:The relationship between the cGAS-stimulator of interferon genes(STING)pathway and liver fibrosis was analyzed using the Gene Expression Omnibus database.Histopathology,immunohistochemistry,fluorescence staining,Western blotting and polymerase chain reaction were performed to assess gene and protein expression levels associated with the cGAS pathway in clinical liver tissue samples and mouse livers.Molecular docking was performed to evaluate the relationship between naringenin and cGAS,and western blotting was performed to study the expression of inflammatory factors downstream of cGAS in vitro.Results:Clinical database analyses showed that the cGAS-STING pathway is involved in the occurrence of chronic liver disease.Naringenin ameliorated liver injury and liver fibrosis,decreased collagen deposition and cGAS expression,and inhibited inflammation in carbon tetrachloride(CCl4)-treated mice.Molecular docking found that cGAS may be a direct target of naringenin.Consistent with the in vivo results,we verified the inhibitory effect of naringenin on activated hepatic stellate cells(HSCs).By using the cGAS-specific agonist double-stranded(ds)DNA,we showed that naringenin attenuated the activation of cGAS and its inflammatory factors affected by dsDNA.We verified that naringenin inhibited the cGAS-STING pathway,thereby reducing the secretion of inflammatory factors by HSCs to ameliorate liver fibrosis.Conclusions:Interrupting the cGAS-STING pathway helped reverse the fibrosis process.Naringenin has potential as an antihepatic fibrosis drug. | Li Chen Siwei Xia Shuqi Wang Yuanyuan Zhou Feixia Wang Zhanghao Li Yang Li Desong Kong Zili Zhang Jiangjuan Shao Xuefen Xu Feng Zhang Shizhong Zheng | 2023 | Journal of Clinical and Translational Hepatology2023，11，1： | 3 |
| 8 | The osmolyte-producing endophyte Streptomyces albidoflavus OsiLf-2 induces drought and salt tolerance in rice via a multi-level mechanism显示文摘Drought and salinity are major environmental stresses that impair crop growth and productivity worldwide. Improving drought and salt tolerance of crops with microbial mutualists is an effective and environmentally sound strategy to meet the demands of the ever-growing world population. In the present study, we found that the Streptomyces albidoflavus Osi Lf-2, a moderately salt-tolerant endophytic actinomycete, produced abundant osmolytes, including proline, polysaccharides, and ectoine. Inoculation with Osi Lf-2 increased the osmotic-adjustment ability of the rice host by increasing the proline content(by250.3% and 49.4%) and soluble sugar(by 20.9% and 49.4%) in rice under drought and salt conditions, relative to the uninoculated control. Osi Lf-2 increased stress responses in the rice host at the physiological and biochemical levels(photosynthesis efficiency, osmolytes and antioxidant content), and the gene level(osmolytes synthesis, stress-responsive and ion-transport related genes), raising rice yields under both greenhouse and saline–alkaline soil conditions. The use of endophytic actinomycetes offers a promising biotechnological approach to developing stress-tolerant plants. | Shuqi Niu Yan Gao Huixian Zi Ying Liu Xuanming Liu Xianqiu Xiong Qingqing Yao Ziwei Qin Ning Chen Liang Guo Yuanzhu Yang Peng Qin Jianzhong Lin Yonghua Zhu | 2022 | The Crop Journal2022，10，2： | 3 |
| 9 | Changes of visceral properties and digestive enzymes in the herbivorous marine teleost Siganus canaliculatus fed on different diets显示文摘The rabbitfish Siganus canaliculatus is one of the few cultured herbivorous marine teleosts. To better understand the digestive physiology of this fish and provide data for designing formulated feed using macroalgae as an ingredient, the changes of visceral properties and digestive enzyme activities were investigated after the juveniles were fed on different types of food including raw fish(RF), formulated diet(FD) or macroalgae Enteromorpha prolifra(EP) and Gracilaria lemaneiformis(GL) for eight weeks. The results showed that the hepatosomatic and viscerosomatic indices in the RF and FD groups, as well as the relative intestine length(RIL) in the EP and GL groups, were significantly higher than those in other groups. Additionally, differences in the histological structure of the liver and anterior intestine were also observed among different dietary groups. The hepatic nuclei were displaced to the periphery by lipid inclusions in fish fed RF. The highest levels of mucosal folds were found in the anterior intestines of fish fed macroalgae. Digestive enzyme activity profiles showed obvious fluctuations in the first three weeks, and then leveled off in the following weeks. The levels of protease, lipase and α-amylase in the alimentary tract showed changes related to the levels of dietary protein, lipid and carbohydrate, respectively.Although macroalgae significantly inhibited the activity of protease in the stomach, it increased RIL and the number of mucosal folds in the anterior intestine so as to compensate for the influences on protease activities in the stomach. This study suggests that the digestive tract of rabbitfish can well adapt to different diets, and needs about three weeks to physiologically acclimatize to the nutritional status, thus implying that rabbitfish are somewhat omnivorous. | XIE Dizhi XU Shude WU Qingyang CHEN Fang WANG Shuqi YOU Cuihong LI Yuanyou | 2018 | Acta Oceanologica Sinica2018，37，2： | 3 |
| 10 | Rab20 is critical for bacterial lipoprotein tolerization-enhanced bactericidal activity in macrophages during bacterial infection显示文摘Bacterial cell wall component-induced tolerance represents an important protective mechanism during microbial infection.Tolerance induced by the TLR2 agonist bacterial lipoprotein(BLP)has been shown to attenuate the inflammatory response,and simultaneously to augment antimicrobial function,thereby conferring its protection against microbial sepsis.However,the underlying mechanism by which BLP tolerance augments bactericidal activity has not been fully elucidated.Here,we reported that the induction of BLP tolerance in murine macrophages upregulated the expression of Rab20,a membrane trafficking regulator,at both the mRNA and protein levels upon bacterial infection.The knockdown of Rab20 with Rab20 specific siRNA(siRab20)did not affect the phagocytosis of Escherichia coli(E.coli),but substantially impaired the intracellular killing of the ingested E.coli in BLP-tolerized macrophages.Furthermore,Rab20 was associated with GFP-E.coli containing phagosomes,and BLP tolerization resulted in the enhanced maturation of GFP-E.coli-containing phagosomes associated with Rab20 and strong lysosomal acidification.The knockdown of Rab20 substantially diminished lysosome acidification and disturbed the fusion of GFP-E.coli containing phagosomes with lysosomes in BLP-tolerized macrophages.These results demonstrate that Rab20 plays a critical role in BLP tolerization-induced augmentation of bactericidal activity via promoting phagosome maturation and the fusion of bacteria containing phagosomes with lysosomes. | Shuqi Zhao Dalin Xi Junwei Cai Wenting Chen Jing Xiang Na Peng Juan Wang Yong Jiang Zhuzhong Mei Jinghua Liu | 2020 | Science China(Life Sciences)2020，63，3： | 2 |
| 11 | Multi-functional vesicles improve Helicobacter pylori eradication by a comprehensive strategy based on complex pathological microenvironment显示文摘Helicobacter pylori(H.pylori),creating a global infection rate over 50%,presents great challenges in clinical therapies due to its complex pathological microenvironment in vivo.To improve the eradication efficacy,herein we fabricated a pharmaceutical vesicle RHL/Cl-Ch-cal where cholesterol-PEG,calcitriol and first-line antibiotic clarithromycin were co-loaded in the rhamnolipid-composed outer lipid layer.RHL/Cl-Ch-cal could quickly penetrate through gastric mucus layer to reach H.pylori infection sites,and then effectively destroyed the architecture of H.pylori biofilms,killed dispersed H.pylori and inhibited the re-adhesion of residual bacteria(called biofilms eradication tetralogy).Moreover,RHL/Cl-Ch-cal activated the host immune response to H.pylori by replenishing cholesterol to repair lipid raft on the cell membrane of host epithelial cells.Finally,RHL/Cl-Ch-cal killed the intracellular H.pylori through recovering the lysosomal acidification and assisting degradation.In experiments,RHL/Cl-Ch-cal demonstrated prominent anti-H.pylori efficacy in the classical H.pylori-infected mice model.Therefore,the study provides a“comprehensive attack”strategy for anti-H.pylori therapies including biofilms eradication tetralogy,immune activation and intracellular bacteria killing. | Xiaonan Chen Yiqing Zou Shuqi Zhang Pengchao Fang Shuxuan Li Pengyu Li Yingying Sun Gang Yuan Haiyan Hu | 2022 | Acta Pharmaceutica Sinica B2022，12，9： | 2 |
| 12 | Genomic and transcriptomic analysis unveils population evolution and development of pesticide resistance in fall armyworm Spodoptera frugiperda显示文摘The fall armyworm(FAW),Spodoptera frugiperda,is a destructive pest native to America and has recently become an invasive insect pest in China.Because of its rapid spread and great risks in China,understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies.Here,we assembled a chromosome-level genome of a male FAW(SFynMstLFR)and compared re-sequencing results of the populations from America,Africa,and China.Strain identification of 163 individuals collected from America,Africa and China showed that both C and R strains were found in the American pop-ulations,while only C strain was found in the Chinese and African populations.Moreover,population geno-mics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations.Taken toge-ther,FAWs invaded into China were most likely origi-nated from Africa.Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW,of which 283 genes are specific to FAW.Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles,and several detoxification genes such as AOX,UGT and GST spe-cially responded to the pesticides.These findings will be useful in developing effective strategies for manage-ment of FAW in China and other invaded areas. | Furong Gui Tianming Lan Yue Zhao Wei Guo Yang Dong Dongming Fang Huan Liu Haimeng Li Hongli Wang Ruoshi Hao Xiaofang Cheng Yahong Li Pengcheng Yang Sunil Kumar Sahu Yaping Chen Le Cheng Shuqi He Ping Liu Guangyi Fan Haorong Lu Guohai Hu Wei Dong Bin Chen Yuan Jiang Yongwei Zhang Hanhong Xu Fei Lin Bernard Slippers Alisa Postma Matthew Jackson Birhan Addisie Abate Kassahun Tesfaye Aschalew Lemma Demie Meseret Destaw Bayeleygne Dawit Tesfaye Degefu Feng Chen Paul K.Kuria Zachary M.Kinyua Tong-Xian Liu Huanming Yang Fangneng Huang Xin Liu Jun Sheng Le Kang | 2022 | Protein & Cell2022，13，7： | 2 |
| 13 | Few-layer metasurfaces with arbitrary scattering properties显示文摘Metasurfaces,which are planar arrays of subwavelength artificial structures,have emerged as excellent platforms for the integration and miniaturization of electromagnetic devices and provided ample possibilities for single-dimensional and multi-dimensional manipulations of electromagnetic waves.However,owing to the limited interactions between planar thin metallic nanostructures and electromagnetic waves as well as intrinsic losses in metals,metasurfaces exhibit disadvantages in terms of efficiency,controllability,and functionality.Recent advances in this field show that few-layer metasurfaces can overcome these drawbacks.Few-layer metasurfaces composed of more than one functional layer enable more degrees of design freedom.Hence,they possess unprecedented capabilities for electromagnetic wave manipulation,which have considerable impact in the area of nanophotonics.This article reviews recent advances in few-layer metasurfaces from the viewpoint of their scattering properties.The scattering matrix theory is briefly introduced,and the advantages and drawbacks of few-layer metasurfaces for the realization of arbitrary scattering properties are discussed.Then,a detailed overview of typical few-layer metasurfaces with various scattering properties and their design principles is provided.Finally,an outlook on the future directions and challenges in this promising research area is presented. | Zhancheng Li Wenwei Liu Hua Cheng Shuqi Chen | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，8： | 2 |

| 15 | 1-Pbps orbital angular momentum fibre-optic transmission显示文摘Space-division multiplexing(SDM),as a main candidate for future ultra-high capacity fibre-optic communications,needs to address limitations to its scalability imposed by computation-intensive multi-input multi-output(MIMO)digital signal processing(DSP)required to eliminate the crosstalk caused by optical coupling between multiplexed spatial channels.By exploiting the unique propagation characteristics of orbital angular momentum(OAM)modes in ring core fibres(RCFs),a system that combines SDM and C+L band dense wavelength-division multiplexing(DWDM)in a 34 km 7-core RCF is demonstrated to transport a total of 24960 channels with a raw(net)capacity of 1.223(1.02)Peta-bit s−1(Pbps)and a spectral efficiency of 156.8(130.7)bit s−1 Hz−1.Remarkably for such a high channel count,the system only uses fixed-size 4×4 MIMO DSP modules with no more than 25 time-domain taps.Such ultra-low MIMO complexity is enabled by the simultaneous weak coupling among fibre cores and amongst non-degenerate OAM mode groups within each core that have a fixed number of 4 modes.These results take the capacity of OAM-based fibre-optic communications links over the 1 Pbps milestone for the first time.They also simultaneously represent the lowest MIMO complexity and the 2nd smallest fibre cladding diameter amongst reported few-mode multicore-fibre(FM-MCF)SDM systems of>1 Pbps capacity.We believe these results represent a major step forward in SDM transmission,as they manifest the significant potentials for further up-scaling the capacity per optical fibre whilst keeping MIMO processing to an ultra-low complexity level and in a modularly expandable fashion. | Junyi Liu Jingxing Zhang Jie Liu Zhenrui Lin Zhenhua Li Zhongzheng Lin Junwei Zhang Cong Huang Shuqi Mo Lei Shen Shuqing Lin Yujie Chen Ran Gao Lei Zhang Xiaobo Lan Xinlun Cai Zhaohui Li Siyuan Yu | 2022 | Light(Science & Applications)2022，11，8： | 1 |
| 16 | In situ synthesis of biomass-derived Ni/C catalyst by self-reduction for the hydrogenation of levulinic acid to γ-valerolactone显示文摘Herein,we reported in situ synthesis of biomass-derived Ni/C catalyst by self-reduction with pomelo peel.Compared with the conventional method, which includes carbonization, activation, impregnation and reduction, the entire preparation process was simplified to two steps, which was more straightforward. This synthesis method was green as Ni/C can be prepared without any additional chemical and the self-reduction process was realized in N2, which can avoid using H2 thus averting some problems such as storage, transportation and safety of H2. Meanwhile, the size and dispersion of Ni particles can be controlled by changing carbonization temperature.The synthesis mechanism of Ni/C catalyst with selfreduction was investigated, which was mainly attributed to the carbon and reducing gas produced during the carbonization process.For the catalytic performance of GVL synthesis, a high yield (94.5%) can be obtained and it exhibited good stability up to 5 cycles without obvious loss of catalytic activity. | Shuqi Fang Zhibing Cui Yuting Zhu Chenguang Wang Jing Bai Xinghua Zhang Ying Xu Qiying Liu Lungang Chen Qi Zhang Longlong Ma | 2019 | Journal of Energy Chemistry2019，28，10： | 1 |

| 19 | Expression of heat-resistant β-glucosidase in Escherichia coli and its application in the production of gardenia blue显示文摘Gardenia blue is a natural blue pigment that is environmentally friendly,non-toxic,and stable.The hydrolysis of geniposide,catalyzed byβ-glucosidase,is a critical step in the production process of gardenia blue.However,β-glucosidase is not resistant to high temperatures,limiting the production of gardenia blue.In this study,we investigated the effectiveness of a heat-resistant glucosidase obtained from Thermotoga maritima in the production of gardenia blue.The enzyme exhibited a maximum activity of 10.60 U/mL at 90℃.Single-factor and orthogonal analyses showed that exogenously expressed heat-resistant glucosidase reacted with 470.3μg/mL geniposide and 13.5μg/mL glycine at 94.2℃,producing a maximum yield of 26.2857μg/mL of gardenia blue after 156.6 min.When applied to the dyeing of denim,gardenia blue produced by this method yielded excellent results;the best color-fastness was achieved when an iron ion mordant was used.This study revealed the feasibility and application potential of microbial production of gardenia blue. | Wenxi Li Jielin Li Ying Xu Yan Huang Shuqi Xu Zirui Ou Xiaoli Long Xinyu Li Xinyu Liu Zening Xiao Jiaqi Huang Weizhao Chen | 2021 | Synthetic and Systems Biotechnology2021，6，3： | 1 |
| 20 | Color-selective three-dimensional polarization structures显示文摘Polarization as an important degree of freedom for light plays a key role in optics.Structured beams with controlled polarization profles have diverse applications,such as information encoding,display,medical and biological imaging,and manipulation of microparticles.However,conventional polarization optics can only realize two-dimensional polarization structures in a transverse plane.The emergent ultrathin optical devices consisting of planar nanostructures,so-called metasurfaces,have shown much promise for polarization manipulation.Here we propose and experimentally demonstrate color-selective three-dimensional(3D)polarization structures with a single metasurface.The geometric metasurfaces are designed based on color and phase multiplexing and polarization rotation,creating various 3D polarization knots.Remarkably,different 3D polarization knots in the same observation region can be achieved by controlling the incident wavelengths,providing unprecedented polarization control with color information in 3D space.Our research findings may be of interest to many practical applications such as vector beam generation,virtual reality,volumetric displays,security,and anti-counterfeiting. | Yuttana Intaravanne Ruoxing Wang Hammad Ahmed Yang Ming Yaqin Zheng Zhang-Kai Zhou Zhancheng Li Shuqi Chen Shuang Zhang Xianzhong Chen | 2022 | Light(Science & Applications)2022，11，11： | 1 |
