| 1 | 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 |
| 2 | 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 |

| 4 | 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 |
| 5 | 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 |
| 6 | 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 |
| 7 | Molecular mechanisms of adaptive evolution in wild animals and plants显示文摘Wild animals and plants have developed a variety of adaptive traits driven by adaptive evolution,an important strategy for species survival and persistence.Uncovering the molecular mechanisms of adaptive evolution is the key to understanding species diversification,phenotypic convergence,and inter-species interaction.As the genome sequences of more and more non-model organisms are becoming available,the focus of studies on molecular mechanisms of adaptive evolution has shifted from the candidate gene method to genetic mapping based on genome-wide scanning.In this study,we reviewed the latest research advances in wild animals and plants,focusing on adaptive traits,convergent evolution,and coevolution.Firstly,we focused on the adaptive evolution of morphological,behavioral,and physiological traits.Secondly,we reviewed the phenotypic convergences of life history traits and responding to environmental pressures,and the underlying molecular convergence mechanisms.Thirdly,we summarized the advances of coevolution,including the four main types:mutualism,parasitism,predation and competition.Overall,these latest advances greatly increase our understanding of the underlying molecular mechanisms for diverse adaptive traits and species interaction,demonstrating that the development of evolutionary biology has been greatly accelerated by multi-omics technologies.Finally,we highlighted the emerging trends and future prospects around the above three aspects of adaptive evolution. | Yibo Hu Xiaoping Wang Yongchao Xu Hui Yang Zeyu Tong Ran Tian Shaohua Xu Li Yu Yalong Guo Peng Shi Shuangquan Huang Guang Yang Suhua Shi Fuwen Wei | 2023 | Science China(Life Sciences)2023，66，3： | 1 |
| 8 | Bit-Level Composite Signal Design for Simultaneous Ranging and Communication显示文摘As the complexity of space exploration missions augments,how to enhance the overall performance of communication,ranging or other functions has become a challengeable problem.Considering the integration of communication and ranging,we present a bit-level composite signal for simultaneous ranging and communication.In this composite method,through a specially designed mapping scheme using low-weight codewords,the information sequence is converted to a sparse sequence which is then superimposed on the ranging code.For ranging,the correlation characteristics of the ranging code component can be maintained to calculate the transmitter-receiver distance.For communications,the sparse sequence can be extracted without interference by eliminating the ranging code component.Simulation results show that the proposed composite signal can support communication and ranging simultaneously with limited sacrifice of ranging performance,and the performance loss of ranging can be controlled and minimized by lowering the density of information sequences using different sparsification encoding methods. | Weigang Chen Yalong He Changcai Han Jinsheng Yang Zhan Xu | 2021 | China Communications2021，18，6： | 1 |
| 9 | Coordinated regulation of BACH1 and mitochondrial metabolism through tumor-targeted self-assembled nanoparticles for effective triple negative breast cancer combination therapy显示文摘The poor prognosis of triple negative breast cancer(TNBC)results from a lack of approved targeted therapies coupled with aggressive proliferation and metastasis,which is associated with high recurrence and short overall survival.Here we developed a strategy by employing tumor-targeted selfassembled nanoparticles to coordinately regulate BACH1(BTB domain and CNC homology 1)and mitochondrial metabolism.The BACH1 inhibitor hemin and mitochondria function inhibitor berberine derivative(BD)were used to prepare nanoparticles(BH NPs)followed by the modification of chondroitin sulfate(CS)on the surface of BH NPs to achieve tumor targeting(CS/BH NPs).CS/BH NPs were found to be able to inhibit tumor migration and invasion by significantly decreasing the amounts of tumor cell metabolites,glycolysis and metastasis-associated proteins,which were related to the inhibition of BACH1 function.Meanwhile,decreased mitochondrial membrane potential,activated caspase 3/9 and increased ROS production demonstrated coordinated regulation of BACH1 and mitochondrial metabolism.In a xenograft mice model of breast cancer,CS/BH NPs significantly inhibited tumor growth and metastasis due to the synergetic effect of hemin and BD without showing obvious toxicities for major organs.In sum,the results of efficacy and safety experiments suggest potential clinical significance of the prepared self-assembled CS/BH nanoparticles for the treatment of TNBC. | Xuan Yang Yalong Wang Junke Zhao Hehui Rong Yujun Chen Mengting Xiong Xiaoxing Ye Shihui Yu Haiyan Hu | 2022 | Acta Pharmaceutica Sinica B2022，12，10： | 1 |
| 10 | A spike-trimer protein-based tetravalent COVID-19 vaccine elicits enhanced breadth of neutralization against SARS-CoV-2 Omicron subvariants and other variants显示文摘Multivalent vaccines combining crucial mutations from phylogenetically divergent variants could be an effective approach to defend against existing and future SARS-Co V-2 variants.In this study,we developed a tetravalent COVID-19 vaccine SCTV01E,based on the trimeric Spike protein of SARS-Co V-2 variants Alpha,Beta,Delta,and Omicron BA.1,with a squalenebased oil-in-water adjuvant SCT-VA02B.In the immunogenicity studies in na?ve BALB/c and C57BL/6J mice,SCTV01E exhibited the most favorable immunogenic characteristics to induce balanced and broad-spectrum neutralizing potencies against pre-Omicron variants(D614G,Alpha,Beta,and Delta)and newly emerging Omicron subvariants(BA.1,BA.1.1,BA.2,BA.3,and BA.4/5).Booster studies in C57BL/6J mice previously immunized with D614G monovalent vaccine demonstrated superior neutralizing capacities of SCTV01E against Omicron subvariants,compared with the D614G booster regimen.Furthermore,SCTV01E vaccination elicited na?ve and central memory T cell responses to SARS-Co V-2 ancestral strain and Omicron spike peptides.Together,our comprehensive immunogenicity evaluation results indicate that SCTV01E could become an important COVID-19 vaccine platform to combat surging infections caused by the highly immune evasive BA.4/5 variants.SCTV01E is currently being studied in a head-to-head immunogenicity comparison phase 3 clinical study with inactivated and m RNA vaccines(NCT05323461). | Rui Wang Hongpeng Huang Chulin Yu Chunyun Sun Juan Ma Desheng Kong Yalong Lin Dandan Zhao Shaozheng Zhou Jianbo Lu Sai Cao Yanjing Zhang Chunxia Luo Xuefeng Li Yang Wang Liangzhi Xie | 2023 | Science China(Life Sciences)2023，66，8： | 1 |
| 11 | Analysis of coast-by noise of heavy truck tires显示文摘Heavy truck tires are one of the main sources of road traffic noise.However,the mechanism and propagation of the noise generated by these tires have not been systematically investigated.To determine the noise of heavy truck tires with different structures and patterns,and to analyze the correlation between the indoor tire noise and coast-by tire noise,an integrated tire indoor noise test and a coast-by noise test were designed and successfully implemented.The indoor test was conducted on a drum inside a semianechoic chamber to simultaneously measure the near field and far field noise of the tires.The outdoor measurements were carried out using a coast-by test on the new ISO 10844 surface.A formula for quantitative analysis with appropriate corrections was developed to analyze the data with reasonable errors,which can be used to predict the coast-by noise through the indoor tire noise test accurately and effectively.The analysis shows that when trying to build the relationship between indoor and outdoor heavy truck tire noise,care should be taken to differentiate the tires with a load capacity index in excess of 121 and without any dual fitting indication from ordinary tires,due to the specified test procedure. | Yintao Wei Yongbao Yang Yalong Chen Hao Wang Dabing Xiang zhichao Li | 2016 | Journal of Traffic and Transportation Engineering(English Edition)2016，3，2： | 1 |
| 12 | DOPA-IGF-1 Coated HA/PLGA Microspheres Promoting Proliferation and Osteoclastic Differentiation of Rabbit Bone Mesenchymal Stem Cells显示文摘To explore the ability of dihydroxyphenylalanine-insulin-like growth factor-1 (DOPA-IGF-1) coated hydroxyapatite/poly(lactic-co-glycolic acid)(HA/PLGA) microspheres to promote the proliferation and osteoclastic differentiation of rabbit bone mesenchymal stem cells(rBMSCs), HA/PLGA microspheres with different HA content (10%, 30%, 50%, mass fraction) were prepared by electrospinning method and HA/PLGA microspheres with 50% HA were coated with IGF-1 and DOPA-IGF-1, respectively. They were co-cultured with rBMSCs, respctively. Cell counting kit-8(CCK-8) detection, confocal laser scanning microscopy(CLSM), alkaline phosphatase(ALP) detection and osteogenesis related genes COL IA1, Runx2 and bone morphogenetic protein-2(BMP-2) detection were conducted to detect the proliferation activity, cell morphology, differentiation ability and the expression level of osteogenesis-related genes of cells cultured on all microspheres groups. The results showed that rBMSCs proliferation increased in an HA content dependent manner, and cells proliferated more in the IGF-1 coated and DOPA-IGF-1 coated groups, in particular in DOPA-IGF-1 coated group, and the differences were more remarkable over time (P<0.05). HA/PLGA microspheres promoted the proliferation and osteogenic differentiation of rBMSCs, and DOPA-IGF-1 coating enhanced the proliferation and osteogenic differentiation of rBMSCs. | LIU Guomin LI Yalong YANG Shuting ZHAO Yian LU Tiancheng JIA Wenyuan JI Xuan LUO Yungang | 2019 | Chemical Research in Chinese Universities2019，35，3： | 1 |
| 13 | Structural limiting factors of mixed-valent tin oxides in photoelectrochemical application:A comparative exploration显示文摘Photoelectrocatalytic(PEC)materials for harvesting solar energy can be discovered from existing photocatalytic semiconductors.Nonetheless,mixed valence tin oxides,a group of widely reported visible light active photocatalysts,can hardly be developed into efficient PEC photoelectrodes.To overcome this difficulty by clarifying its origin,two typical mixed valence tin oxides,Sn^(2+):SnO_(2) microrods and porous Sn_(3)O_(4) particles were deliberately prepared as the models.Sn^(2+):SnO_(2) microrods of less porosity exhibited a photocurrent over ten times higher than Sn_(3)O_(4) particles.Photo-electrochemical impedance spectroscopy revealed this was due to their charge kinetics difference,specifically the internal transport/-transfer responding to the morphology.Moreover,hydroxyl residuals from synthesis were found to be very inhibitive for the PEC efficiency as well,which was in coherence with our TGA and Raman spectroscopic study.These finding experimentally proved the necessity of reconsidering the surface area,crystallinity,and defects when developing photocatalysts into efficient PEC structures. | Yalong Zou Deyu Liu Xiangrui Meng Qitao Liu Yang Zhou Jianming Li Zhiying Zhao Ding Chen Yongbo Kuang | 2021 | Journal of Energy Chemistry2021，30，5： | 0 |
| 14 | Was Wuhan the early epicenter of the COVID-19 pandemic?——a critique显示文摘Recently, Worobey et al.(2022) published a report entitled ‘The Huanan Seafood Wholesale Market in Wuhan was the early epicenter of the COVID-19 pandemic' that succinctly summarizes their study [1]. A pre-print version of this study had earlier elicited a series of highprofile media coverages [2,3]. All these reports deliver a social-political message that the Huanan market is the epicenter of COVID-19. | Yanan Cao Lingling Chen Hua Chen Yupeng Cun Xiaofeng Dai Hongli Du Feng Gao Fengbiao Guo Yalong Guo Pei Hao Shunmin He Shunping He XiongLei He Zheng Hu Boon-Peng Hoh Xin Jin Qian Jiang Qinghua Jiang Asifullah Khan Hong-Zhi Kong Jinchen Li Shuai Cheng Li Ying Li Qiang Lin Jianquan Liu Qi Liu Jian Lu Xuemei Lu Shujin Luo Qinghua Nie Zilong Qiu Tieliu Shi Xiaofeng Song Jianzhong Su Sheng-ce Tao Chaolong Wang Chuan-Chao Wang Guo-Dong Wang Jiguang Wang Qi Wu Shaoyuan Wu Shuhua Xu Yu Xue Wenjun Yang Zhaohui Yang Kai Ye Yuan-Nong Ye Li Yu Fangqing Zhao Yiqiang Zhao Weiwei Zhai Dandan Zhang Liye Zhang Houfeng Zheng Qi Zhou Tianqi Zhu Ya-ping Zhang | 2023 | National Science Review2023，10，4： | 0 |

| 16 | The application of virtual reality training for anastomosis during robot-assisted radical prostatectomy显示文摘Objective:To investigate the application of virtual reality training in vesicourethral anastomosis during robot-assisted radical prostatectomy(RARP).Methods:Three certified robotic urologists who underwent virtual reality training were enrolled in the study group.The other three without training were enrolled in the control group.Parameters were recorded before and after the training.Then a total of 18 patients undergoing RARP were enrolled and randomized assigned to receive anastomosis procedures with certified urologists who either obtained or did not obtain training.The quality of the anastomosis was evaluated.Results:For the virtual training evaluation,the overall score was significantly improved from 65.0±10.8 to 92.7±3.5(p=0.014);the time of anastomosis was shortened;the economy of motion improved;instrument collisions decreased after training(p<0.05).Besides,the effectiveness of the virtual training was evaluated in the 18 real anastomosis procedures which were completed either by three urologists with training or three urologists without training.Most intriguingly,the average time of anastomosis was shortened from 40.0±12.4 min to 25.1±7.1 min(p=0.015).The parameters including time of operation,creatinine level of drainage,postoperative hospital stay and duration of catheter drainage were comparable before and after training.Two leakages,which were observed in procedures by doctors without training,needed salvage sutures by a senior doctor.Conclusions:Virtual reality training enabled surgeons to become quickly familiar with robotic system manipulation,improved their skills for vesicourethral anastomosis and shortened the learning curve,thus helping them operate with high efficacy and quality. | Fubo Wang Chao Zhang Fei Guo Xia Sheng Jin Ji Yalong Xu Zhi Cao Ji Lyu Xiaoying Lu Bo Yang | 2021 | Asian Journal of Urology2021，8，2： | 0 |
| 17 | The effect of Pickering emulsion adjuvants on the immune efficacy of the COVID-19 polypeptide vaccine显示文摘Pickering emulsions were prepared by phacoemulsification in an ice water bath with squalene as the oil phase and an aluminum adjuvant as the particle stabilizer.The effects of formulation and process conditions on the size and distribution of the Pickering emulsions were investigated.Pickering emulsions prepared under the optimal prescription and process conditions were mixed with a peptide antigen to obtain a peptide vaccine.The optimal prescription and process condition of the Pickering emulsion is as follows:squalene as the oil phase,ultra-pure water as the water phase with 5 mg/mL aluminum adjuvant,and an ultrasonication time of 4 min at 200 W power.BALB/c mice were immunized with the peptide vaccine,and the ability of the Pickering emulsion as an immunological adjuvant to improve the efficacy of the peptide vaccine was evaluated.Under optimal conditions,a Pickering emulsion with a small particle size(430.8 nm),uniform distribution(polydispersion index of 16.9%),and zeta potential of 31.5 mV,was obtained.Immunological results showed that the serum specific antibody level in the vaccinated group reached 1×104 after three immunizations.The proportion of CD4+T cells and CD4/CD8 cells was significantly higher(P<0.05)in the vaccinated groups than the blank control group.Further,cytokine(TNF-��)secretion decreased in the aluminum adjuvant and Pickering emulsion groups but increased in the Freund’s adjuvant group.All three vaccinated groups of mice exhibited low but detectable levels of IFN-��secretion. | Zhuanqing Huang Qi Sun Haoyuan Shi Sen Yang Yuanyuan Li Yue Ma Fei Yang Zhenwei Shi Yalong Yang Ying Zhang Hui Gong Fenghua Xu | 2023 | ChemPhysMater2023，2，3： | 0 |
| 18 | Real- and momentum-indirect neutral and charged excitons in a multi-valley semiconductor显示文摘Excitons dominate the photonic and optoelectronic properties of a material.Although significant advancements exist in understanding various types of excitons,progress on excitons that are indirect in both real-and momentum-spaces is still limited.Here,we demonstrate the real-and momentum-indirect neutral and charged excitons(including their phonon replicas)in a multi-valley semiconductor of bilayer MoS_(2),by performing electric-field/doping-density dependent photoluminescence.Together with first-principles calculations,we uncover that the observed real-and momentum-indirect exciton involves electron/hole from K/Γvalley,solving the longstanding controversy of its momentum origin.Remarkably,the binding energy of real-and momentum-indirect charged exciton is extremely large(i.e.,~59 meV),more than twice that of real-and momentum-direct charged exciton(i.e.,~24 meV).The giant binding energy,along with the electrical tunability and long lifetime,endows real-and momentum-indirect excitons an emerging platform to study many-body physics and to illuminate developments in photonics and optoelectronics. | Zhiheng Huang Yuhui Li Tao Bo Yanchong Zhao Fanfan Wu Lu Li Yalong Yuan Yiru Ji Le Liu Jinpeng Tian Yanbang Chu Xiaozhou Zan Yalin Peng Xiuzhen Li Yangkun Zhang Kenji Watanabe Takashi Taniguchi Zhipei Sun Wei Yang Dongxia Shi Shixuan Du Luojun Du Guangyu Zhang | 2023 | National Science Open2023，2，4： | 0 |
| 19 | Instant formation of excellent oxygen evolution catalyst film via controlled spray pyrolysis for electrocatalytic and photoelectrochemical water splitting显示文摘The retarded kinetics of oxygen evolution on electrodes is a bottleneck for electrochemical energy conversion and storage systems.NiFe-based electrocatalysts provide a cost-effective choice to confront this challenge.However,there is a lack of facile techniques for depositing compact catalytic films of high coverage and possessing a state-of-the-art performance,which is especially desired in photoelectrochemical(PEC)systems.Herein,we demonstrate a spray pyrolysis(SP)route to address this issue,featuring the kinetic selective preparation towards the desired catalytic-active material.Differing from reported SP protocols which only produce inactive oxides,this approach directly generates a unique composite film consisting of NiFe layered oxyhydroxides and amorphous oxides,exhibiting an overpotential as small as 255 mV(10 mA cm^(−2))and a turnover frequency of∼0.4 s^(−1)per metal atom.By using such a facile protocol,the surface rate-limiting issue of BiVO_(4)photoanodes can be effectively resolved,resulting in a charge injection efficiency of over 90%.Considering this deposition directly start from simple nitrates but only takes several seconds to complete,we believe it can be developed as a widely applicable and welcomed functionalization technique for diverse electrochemical devices. | Na An Hengzheng Tian Yang Zhou Yalong Zou Hao Xiu Yufeng Cao Ying Wang Jianming Li Deyu Liu Yongbo Kuang | 2022 | Journal of Energy Chemistry2022，31，3： | 0 |
| 20 | Directly imaging of the atomic structure of luminescent centers in CaYAlO_(4):Ce^(3+)显示文摘Lanthanides(Ln^(3+))doped luminescent materials play critical roles in lighting and display techniques.While increasing experimental and theoretical research have been carried out on aluminate-based phosphors for white light-emitting diodes(WLEDs)over the past decades,most investigation was mainly focused on their luminescent properties;therefore,the local structure of the light emission center remains unclear.Especially,doping-induced local composition and structure modification around the luminescent centers have yet to be unveiled.In this study,we use advanced electron microscopy techniques including electron diffraction(ED),high-resolution transmission electron microscopy(HRTEM),high-angle annular dark-field scanning transmission electron microscopy(HAADF-STEM),in combination with energy dispersive X-ray spectroscopy(EDX)and electron energy loss spectroscopy(EELS),to reveal atomically resolved crystalline and chemical structure of Ce^(3+)doped CaYAlO4.The microscopic results prove substantial microstructural and compositional inhomogeneities in Ce^(3+)doped CaYAlO_(4),especially the appearance of Ce dopant clustering and Ce^(3+)/Ce^(4+)valence variation.Our research provides a new understanding the structure of Ln^(3+)doped luminescent materials and will facilitate the materials design for next-generation WLEDs luminescent materials. | Yalong Zhai Xuewei Yang Shu-Na Zhao Pei Liu Jun Lin Yang Zhang | 2023 | Nano Research2023，16，2： | 0 |
