| 2 | Metaverse:Perspectives from graphics,interactions and visualization显示文摘The metaverse is a visual world that blends the physical world and digital world.At present,the development of the metaverse is still in the early stage,and there lacks a framework for the visual construction and exploration of the metaverse.In this paper,we propose a framework that summarizes how graphics,interaction,and visualization techniques support the visual construction of the metaverse and user-centric exploration.We introduce three kinds of visual elements that compose the metaverse and the two graphical construction methods in a pipeline.We propose a taxonomy of interaction technologies based on interaction tasks,user actions,feedback and various sensory channels,and a taxonomy of visualization techniques that assist user awareness.Current potential applications and future opportunities are discussed in the context of visual construction and exploration of the metaverse.We hope this paper can provide a stepping stone for further research in the area of graphics,interaction and visualization in the metaverse. | Yuheng Zhao Jinjing Jiang Yi Chen Richen Liu Yalong Yang Xiangyang Xue Siming Chen | 2022 | Visual Informatics2022，6，1： | 10 |
| 3 | U-Pb zircon geochronology, geochemistry and kinetics of the Huaniushan A-type granite in Northwest China显示文摘The Huaniushan granite is located at the Beishan orogenic belt, northwestern China. At the contact zone between the granite and marble, a hydrothermal Pb-Zn and skarn Au deposit is formed. LA-ICP-MS zircon U-Pb dating yielded a weighted mean 206Pb/238U age of 229.5±2.6 Ma (MSDW=0.93) for the Huaniushan granite, imply-ing its Late Triassic intrusion. Geochemistry analyses show that the Huaniushan granite is enriched in Si, K, Na, and REE, and depleted in Mg and Ca, with contents of SiO2 (70.8% to 74.4%), Na2O+K2O (8.8% to 10.2%), CaO (0.93% to 1.44%), and MgO (0.14% to 0.48%). REE is characterized by obvious negative Eu anomaly. Rb, Th, U, K, Pb, Nb, Zr and Hf elements are rich in the granite while Ba, Sr, P, Ti and Eu are deplete. The granite has a high (Zr+Nb+Ce+Y) abundance and 104 Ga/Al ratios. Petrology, major and trace elements data all indicate that the Hua-niushan granite is A-type granite which intruded in a post-collisional extensional tectonic setting. The magma was dominantly sourced from partial melting of crustal intermediate-felsic igneous rocks. Intensive magmatic activities and Au-Cu-Mo mineralization occurred throughout the Beishan orogenic belt during the period from ca. 240 to 220 Ma. | ZHU Jiang LÜ Xinbiao CAO Xiaofeng MO Yalong CHEN Chao | 2012 | Chinese Journal Of Geochemistry2012，31，1： | 10 |

| 5 | High‑Energy and High‑Power Pseudocapacitor–Battery Hybrid Sodium‑Ion Capacitor with Na^(+) Intercalation Pseudocapacitance Anode显示文摘High-performance and low-cost sodium-ion capacitors(SICs)show tremendous potential applications in public transport and grid energy storage.However,conventional SICs are limited by the low specific capacity,poor rate capability,and low initial coulombic efficiency(ICE)of anode materials.Herein,we report layered iron vanadate(Fe5V15O39(OH)9·9H2O)ultrathin nanosheets with a thickness of~2.2 nm(FeVO UNSs)as a novel anode for rapid and reversible sodium-ion storage.According to in situ synchrotron X-ray diffractions and electrochemical analysis,the storage mechanism of FeVO UNSs anode is Na+intercalation pseudocapacitance under a safe potential window.The FeVO UNSs anode delivers high ICE(93.86%),high reversible capacity(292 mAh g^−1),excellent cycling stability,and remarkable rate capability.Furthermore,a pseudocapacitor–battery hybrid SIC(PBH-SIC)consisting of pseudocapacitor-type FeVO UNSs anode and battery-type Na3(VO)2(PO4)2F cathode is assembled with the elimination of presodiation treatments.The PBH-SIC involves faradaic reaction on both cathode and anode materials,delivering a high energy density of 126 Wh kg^−1 at 91 W kg^−1,a high power density of 7.6 kW kg^−1 with an energy density of 43 Wh kg−1,and 9000 stable cycles.The tunable vanadate materials with high-performance Na+intercalation pseudocapacitance provide a direction for developing next-generation highenergy capacitors. | Qiulong Wei Qidong Li Yalong Jiang Yunlong Zhao Shuangshuang Tan Jun Dong Liqiang Mai Dong‑Liang Peng | 2021 | Nano-Micro Letters2021，13，3： | 4 |
| 6 | Sedimentology and Sequence Stratigraphy of Marine to Lacustrine Deltaic Deposits in a Craton Basin and Their Controlling Factors: Shan 2 Member–He 8 Member(Guadalupian–Lopingian, Permian), Southeast Ordos Basin, North China显示文摘The Shan 2 Member, Shan 1 Member and He 8 Member of the Mid–Late Permian Shanxi and lower Xiashihezi formations, in the southeastern Ordos Basin, together comprise ~150 m of deltaic deposits. This sequence records an overall evolution from deep marine environment to shallow lake associated with braided river, braided river delta and meandering river delta. Core description, well log interpretation, and stable isotope analysis, including carbon, oxygen and strontium, were conducted to understand the sedimentary evolution of Shan 2 to He 8 Member. The Shanxi Formation, which consists of the Shan 2 and Shan 1 members, is characterized by a tidal-influenced meandering river delta environment and a higher δ^(13)C value and ^(87)Sr?(^(86)Sr) ratio and a lower δ^(18)O value. The He 8 Member, the basal part of the Xiashihezi Formation, is featured by a braided river to braided river delta system and a lower δ^(13)C value, ^(87)Sr?(^(86)Sr) ratio, and a higher δ^(18)O value. Four third-order depositional sequences separated by five sequence boundaries are determined. Coarsening upward sequences of the Shan 2 Member–He 8 Member indicate a general regression trend, which can be correlated to global sea-level fall occurring during the Roadian–Wuchiapingian, as also evidenced by previous published zircon U–Pb results. The coal-bearing sequence(Shanxi Formation) to non-coal-bearing sequence(He 8 Member), as well as a decrease of ^(87)Sr?(^(86)Sr), suggest a trend from humid to arid climates. A combined effect of sea-level drop and a small uplift at the end of Shanxi Formation are proposed. | SHAN Xin YU Xinghe Peter CLIFT LI Yalong JIN Lina SU Dongxu DU Yonghui ZHOU Jinsong HAN Xiaoqin | 2018 | Acta Geologica Sinica(English Edition)2018，92，1： | 4 |

| 8 | Oxygen vacancy-engineered BaTiO_(3)nanoparticles for synergistic cancer photothermal,photodynamic,and catalytic therapy显示文摘With the rapid development of photo-responsive nanomaterials,photo-triggered therapeutic strategies such as photothermal therapy(PTT)and photodynamic therapy(PDT)have been new alternatives to current cancer therapeutic methods.Herein,we have fabricated oxygen vacancy-engineered BaTiO_(3)(BTO-Ov)nanoparticles(NPs)for near-infrared(NIR)light-triggered PTT,PDT,and catalytic therapy cooperatively for significantly improving cancer therapy.Compared to pristine BaTiO_(3)nanoparticles,BTO-Ov has stronger NIR light absorption and narrower band gap structure,which results in superior photothermal conversion and superoxide radical generation capabilities through PTT and PDT.Meanwhile,due to the existence of Ti^(3+),BTO-Ov also exhibits peroxidase(POD)-like activity to produce hydroxyl radical under tumor environment,which can be further improved under 808 nm light irradiation.Both in vitro and in vivo results demonstrate that such a multifunctional therapeutic nanoplatform can achieve a high therapeutic efficacy triggered by a single NIR light irradiation.The defect engineering strategy can be used as a general approach to fabricate multifunctional cancer therapeutic nanoplatform. | Yiming Ding Zhuo Wang Zeyu Zhang Yunchao Zhao Shangyu Yang Yalong Zhang Shuncheng Yao Shaobo Wang Tian Huang Yang Zhang Linlin Li | 2022 | Nano Research2022，15，8： | 3 |
| 9 | Low-strain TiP_(2)O_(7) withthree-dimensionalionchannelsas long-life and high-rate anode material for Mg-ion batteries显示文摘Rechargeable magnesium batteries are identified as a promising next-generation energy storage system,but their development is hindered by the anode−electrolyte−cathode incompatibilities and passivation of magnesium metal anode.To avoid or alleviate these problems,the exploitation of alternative anode materials is a promising choice.Herein,we present titanium pyrophosphate(TiP_(2)O_(7))as anode materials for magnesium-ion batteries(MIBs)and investigate the effect of the crystal phase on its magnesium storage performance.Compared with the me-tastable layered TiP_(2)O_(7),the thermodynamically stable cubic TiP_(2)O_(7) displays a better rate capability of 72 mAh g^(−1) at 5000 mA g^(−1).Moreover,cubic TiP_(2)O_(7) exhibits excellent cycling stability with the capacity of 60 mAh g^(−1) after 5000 cycles at 1000 mA g^(−1),which are better than pre-viously reported Ti-based anode materials for MIBs.In situ X-ray diffraction technology confirms the single-phase magnesiumion inter-calation/deintercalation reaction mechanism of cubic TiP_(2)O_(7) with a low volume change of 3.2%.In addition,the density functional theory calcu-lation results demonstrate that three-dimensional magnesiumion diffu-sion can be allowed in cubic TiP_(2)O_(7) with a low migration energy barrier of 0.62 eV.Our work demonstrates the promise of TiP_(2)O_(7) as high-rate and long-life anode materials for MIBs and may pave the way for further development of MIBs. | Fangyu Xiong Yalong Jiang Li Cheng Ruohan Yu Shuangshuang Tan Chen Tang Chunli Zuo Qinyou An Yunlong Zhao Jean-Jacques Gaumet Liqiang Mai | 2022 | Interdisciplinary Materials2022，1，1： | 3 |
| 10 | Noble-metal free plasmonic nanomaterials for enhanced photocatalytic applications—A review显示文摘Plasmonic nanomaterial catalysis is currently at the frontier of photocatalysis,overcoming the limitations of wide bandgap semiconductors for light absorption.Its localized surface plasmon resonance(LSPR)properties allow broad ultraviolet-visible-near infrared ray(UV-vis-NIR)absorption,making it an ideal material for solar energy conversion.Most plasmonic nanostructures rely on precious metals.Although noble metal plasmonic nanomaterials have proven to be one of the strategies for enhancing photocatalytic activity,their expensive cost and limitations in light absorption range have hindered their practical application.As a result,noble-metal free plasmonic nanomaterials have risen to the top of the research priority list.Therefore,this paper reviews the fundamental principles and classification of the LSPR effect of noble-metal free plasmonic nanomaterials in photocatalytic and their recent applications in hydrogen generation,carbon dioxide reduction,and pollutant degradation.Specific cases elucidate the possible working mechanism of enhanced photocatalysis by noble-metal free plasmonic nanomaterials.Finally,the challenges and future opportunities for noble-metal free plasmonic nanomaterials in energy conversion and storage are discussed and envisioned. | Jinghua Li Yiming Zhang Yalong Huang Bing Luo Li Jing Dengwei Jing | 2022 | Nano Research2022，15，12： | 3 |
| 11 | An improved method of absolute calibration to satellite altimeter: A case study in the Yellow Sea, China显示文摘An improved absolute calibration technology based on indirect measurements was developed through two probative experiments, the performance of which was evaluated by applying the approach to in situ sea surface height(SSH) at the Tianheng Island(tidal gauge) and the satellite nadir(GPS buoy). Using Geoid/MSS(mean sea surface) data, which accounted for a constant offset between nadir and onshore tidal gauge water levels, and TMD(tidal model driver), which canceled out the time-varying offsets, nadir SSH(sea surface height) could be indirectly acquired at an onshore tidal gauge instead of from direct offshore observation. The approach extrapolated the onshore SSH out to the offshore nadir with an accuracy of(1.88±0.20) cm and a standard deviation of 3.3 cm, which suggested that the approach presented was feasible in absolute altimeter calibration/validation(Cal/Val), and the approach enormously facilitated the obtaining SSH from the offshore nadir. | LIU Yalong TANG Junwu ZHU Jianhua LIN Mingsen ZHAI Wanlin CHEN Chuntao | 2014 | Acta Oceanologica Sinica2014，33，5： | 3 |
| 12 | Cross-species single-cell transcriptomic analysis reveals divergence of cell composition and functions in mammalian ileum epithelium显示文摘Animal models are widely used for biomedical studies and drug evaluation.The small intestine plays key roles in nutrient absorption,hormone secretion,microbiota defense and drug absorption and metabolism.Although the intestinal structure of mammals is conserved,the differences on epithelial cell composition,functional assignments and drug absorption among mammals are largely unknown.Here,cross-species analysis of single-cell transcriptomic atlas of the ileum epithelium from mouse,rat,pig,macaque and human reveals the conserved and differential cell types and functions among species,identifies a new CA7+cell type in pig,macaque and human ileum,uncovers the distinct expression pattern in enterocytes,enteroendocrine cells and Paneth cells,and defines the conserved and species-specific intestinal stem cell signature genes.The examination of drug absorption across species suggests that drug metabolism in mouse ileum is closer to human while drug transport in macaque ileum is more similar to human.Together,our data provide the comprehensive information about cell composition and functional assignments in five species,and offer the valuable guidance for animal model selection and drug testing. | Haonan Li Xiaodan Wang Yalong Wang Mengxian Zhang Fan Hong Hong Wang Along Cui Jianguo Zhao Weizhi Ji Ye-Guang Chen | 2022 | Cell Regeneration2022，11，1： | 2 |
| 13 | Intestinal cellular heterogeneity and disease development revealed by single-cell technology显示文摘The intestinal epithelium is responsible for food digestion and nutrient absorption and plays a critical role in hormone secretion,microorganism defense,and immune response.These functions depend on the integral single-layered intestinal epithelium,which shows diversified cell constitution and rapid self-renewal and presents powerful regen-eration plasticity after injury.Derailment of homeostasis of the intestine epithelium leads to the development of dis-eases,most commonly including enteritis and colorectal cancer.Therefore,it is important to understand the cellular characterization of the intestinal epithelium at the molecular level and the mechanisms underlying its homeostatic maintenance.Single-cell technologies allow us to gain molecular insights at the single-cell level.In this review,we summarize the single-cell RNA sequencing applications to understand intestinal cell characteristics,spatiotemporal evolution,and intestinal disease development. | Yalong Wang Wanlu Song Shicheng Yu Yuan Liu Ye-Guang Chen | 2022 | Cell Regeneration2022，11，1： | 2 |
| 14 | A review of in situ upgrading technology for heavy crude oil显示文摘With the growing demand of oil worldwide,heavy oil has increasingly become vital in the world energy market.However,further development of heavy oil reservoirs are limited by regular enhanced oil recovery(EOR)methods.In situ upgrading technology provides potential for the development of heavy oil and bitumen reservoirs.This study reviews three categories of in situ upgrading methods:solvent-based,in situ combustion(ISC),and catalytic.Solvent-based methods,including cyclic solvent injection,vapor extraction,and hybrid processes,have recently received attention and have been progressed in both laboratory and field applications.However,high solvent costs in relation to the low price of heavy oil have continued to limit the field applications of these techniques.ISC,which may have the potential to develop particularly harsh reservoirs with extremely viscous crude oil,involves complex reaction mechanisms and consists of three main steps:oxidation,combustion,and gas flooding.Yet,complex operating conditions and a low success rate have restricted its application.Catalytic methods,which have demonstrated the potential to refine and upgrade crude oil in a more economic and environmentally friendly way,are often accompanied by conventional thermal EOR methods,such as steam flooding and ISC,and involve a series of hydroprocessing or hydrotreating reactions,such as hydrocracking,hydrodesulfurization,hydrodenitrogenation,hydrodeoxygenation,and hydrodemetallization.However,the high cost and complexity of the reaction mechanisms have limited their applications. | Yibo Li Zhiqiang Wang Zhiming Hu Yalong Li Wanfen Pu Jinzhou Zhao | 2021 | Petroleum2021，7，2： | 2 |
| 15 | Inversion of surface vegetation water content based on GNSS-IR and MODIS data fusion显示文摘Obtaining high-precision,long-term sequences of vegetation water content(VWC)is of great significance for assessing surface vegetation growth,soil moisture,and fire risk.In recent years,the global navigation satellite system-interferometric reflection(GNSS-IR)has become a new type of remote sensing technology with low cost,all-weather capability,and a high temporal resolution.It has been widely used in the fields of snow depth,sea level,soil moisture content,and vegetation water content.The normalized microwave reflectance index(NMRI)based on GNSS-IR technology has been proven to be effective in monitoring changes in VWC.This paper considers the advantages and disadvantages of remote sensing technology and GNSS-IR technology in estimating VWC.A point-surface fusion method of GNSS-IR and MODIS data based on the GA-BP neural network is proposed to improve the accuracy of VWC estimation.The vegetation index products(NDVI,GPP,LAI)and the NMRI that unified the temporal and spatial resolution were used as the input and output data of the training model,and the GA-BP neural network was used for training and modeling.Finally,a spatially continuous NMRI product was generated.Taking a particular area of the United States as a research object,experiments show that(1)a neural network can realize the effective fusion of GNSS-IR and MODIS products.By comparing the GA-BP neural network,BP neural network,and multiple linear regression(MLR),the three models fusion effect.The results show that the GA-BP neural network has the best modeling effect,and the r and RMSE between the model estimation result and the reference value are 0.778 and 0.0332,respectively;this network is followed by the BP neural network,in which the r and RMSE are 0.746 and 0.0465,respectively.MLR has the poorest effect,with r and RMSE values of 0.500 and 0.0516,respectively.(2)The spatiotem-poral variation in the 16 days/500 m resolution NMRI product obtained by GA-BP neural network fusion is consistent with that in the experimental area.Through the testing of GNSS stations that did not participate in the modeling,the r between the estimated value of the NMRI and the reference value is greater than 0.87,and the RMSE is less than 0.049.Therefore,the method proposed in this paper is optional and effective.The spatially continuous NMRI products obtained by fusion can reflect the changes in VWC in the experimental area more intuitively. | Yalong Pan Chao Ren Yueji Liang Zhigang Zhang Yajie Shi | 2020 | Satellite Navigation2020，1，1： | 2 |

| 17 | Origin of the springtime South China Sea Warm Current in the southwestern Taiwan Strait: Evidence from seawater oxygen isotope显示文摘Oxygen isotope(δ^18O)of seawater is an excellent proxy for tracing the origins of water masses and their mixing processes.Combining with hydrographic observation,hybrid coordinate ocean model(HYCOM)analysis data,and seawater oxygen isotope,we investigated the source of the South China Sea Warm Current(SCSWC)in the southwestern Taiwan Strait and its underlying mechanism.Results show that the Kuroshio subsurface water(KSSW)can intrude the continental slope in the southwestern Taiwan Strait,and thereby climb up the continental slope coupled with upwelling.Theδ^18O-salinity relationship further indicates that in spring,the SCSWC in the southwestern Taiwan Strait originates from the upslope deflection of the slope current formed by the KSSW intrusion into the South China Sea,rather than from the west segment of the SCSWC formed to the east of Hainan Island.In addition,the southward flowing Zhe-Min Coastal Current(ZMCC)can reach as far as the Taiwan Bank(TB)and deflects offshore over the western TB at approximately 23.5°N,to some extent affecting the SCSWC.Moreover,this study reveals that seawaterδ^18O is exquisitely sensitive to the determination of the origin and transport of water masses as compared with traditional potential temperature-salinity plot(θ-S)and HYCOM analysis data.In addition,their coupling can more reliably interpret the mixing processes of shelf water masses. | Dongyu CHEN Ergang LIAN Yeqiang SHU Shouye YANG Yalong LI Chao LI Pengfei LIU Ni SU | 2020 | Science China Earth Sciences2020，63，10： | 2 |
| 18 | Surface pseudocapacitance of mesoporous Mo_(3)N_(2) nanowire anode toward reversible high-rate sodium-ion storage显示文摘Sodium-ion storage devices are highly desirable for large-scale energy storage applications owing to the wide availability of sodium resources and low cost.Transition metal nitrides(TMNs)are promising anode materials for sodium-ion storage,while their detailed reaction mechanism remains unexplored.Herein,we synthesize the mesoporous Mo3N2 nanowires(Meso-Mo_(3)N_(2)-NWs).The sodium-ion storage mechanism of Mo3N2 is systematically investigated through in-situ XRD,ex-situ experimental characterizations and detailed kinetics analysis.Briefly,the Mo_(3)N_(2) undergoes a surface pseudocapacitive redox charge storage process.Benefiting from the rapid surface redox reaction,the Meso-Mo_(3)N_(2)-NWs anode delivers high specific capacity(282 m Ah g^(-1) at 0.1 A g^(-1)),excellent rate capability(87 m Ah g^(-1) at 16 A g^(-1))and long cycling stability(a capacity retention of 78.6%after 800 cycles at 1 A g^(-1)).The present work highlights that the surface pseudocapacitive sodium-ion storage mechanism enables to overcome the sluggish sodium-ion diffusion process,which opens a new direction to design and synthesize high-rate sodiumion storage materials. | Yalong Jiang Jun Dong Shuangshuang Tan Qiulong Wei Fangyu Xiong Wei Yang Yuanhao Shen Qingxun Zhang Zi'ang Liu Qinyou An Liqiang Mai | 2021 | Journal of Energy Chemistry2021，30，4： | 2 |
| 19 | Numerical Simulation and Shrinkage Defects Prediction of a Turbine Blade Investment Casting显示文摘By adopting the solid modeling software SoldEdge and the enmeshment software SRIFCast as the pre-processingplatform, a Ni based alloy turbine blade was three-dimensionally modeled and automatically enmeshed. A softwarecode for numerical simulation of fluid flow and heat transfer was developed. The Xue criterion and Niyama criterionwere used to predict the position of the shrinkage defects occurring in the solidification processes of the turbine blade.The results showed that both Xue and Niyama criteria could precisely predict the shrinkage defects in the Ni basedalloy turbine blade. This indicates that numerical simulation is a significant tool in improving casting quality. | Jing TIAN Xiang XUE Yuebing ZHANG Yalong GAO Luzhi LIU Qin SUN Shiyou YUAN | 2003 | Journal of Materials Science & Technology2003，19，z1： | 2 |
| 20 | Effect of stagger angle on capillary performance of microgroove structures with reentrant cavities显示文摘Aluminum-based microgroove surfaces with reentrant cavities (MSRCs) were fabricated by two staggered ploughing/extrusion processes to meet the requirements of lightweight phase change heat transfer devices.Five MSRCs with different stagger angles between cavities and microgrooves (MGs) were fabricated to study the effect of stagger angle on capillary performance.Capillary rise and permeability tests were performed on all MSRCs and the results were compared with MGs having the same processing parameters.It was found that MSRCs with smaller stagger angles have higher capillary height,and the maximum enhancement maintained by MSRC45 was about 54.84%.However,MSRCs with larger stagger angles were found to have higher permeability.Therefore,the capillary parameter K·ΔP_(cap)was used as a comprehensive index to evaluate these wicks.MSRC90 and MSRC75 obtained the largest K·ΔP_(cap)values without and with the effect of gravity considered,respectively.Although all MSRCs had a higher capillary rise height than MGs,smaller stagger angles (≤60°) seriously reduced the permeability of MSRCs and even resulted in smaller K·ΔP_(cap)value than that of MGs when calculated considering the effect of gravity.Therefore,MSRCs with larger stagger angles (≥75°) may be the optimum wicks due to the good balance between capillary pressure and permeability. | SUN YaLong LIANG FuYe TANG Yong TANG Heng XI XiaoQian YANG Shu FU Ting | 2021 | Science China(Technological Sciences)2021，64，7： | 2 |
