1Screening for gastric cancer in China:Advances,challenges and visions显示文摘Gastric cancer(GC)is one of the major cancers in China and all over the world.Most GCs are diagnosed at an advanced stage with unfavorable prognosis.Along with some other countries,China has developed the government-funded national screening programs for GC and other major cancers.GC screening has been shown to effectively decrease the incidence of and mortality from GC in countries adopting nationwide screening programs(Japan and Korea)and in studies based on selected Chinese populations.The screening of GC relies mostly on gastroendoscopy,the accuracy,reliability and safety of which have been indicated by previous studies.However,considering its invasive screening approach,requirements on skilled endoscopists and pathologists,and a high cost,developing noninvasive methods to amend endoscopic screening would be highly needed.Numerous studies have examined biomarkers for GC screening and the combination of biomarkers involving pepsinogen,gastrin,and Helicobacter pylori antibodies has been proposed for risk stratification,seeking to narrow down the high-risk populations for further endoscopy.Despite all the achievements of endoscopic screening,evidence on appropriate screening age,intervals for repeated screening,novel biomarkers promoting precision prevention,and health economics need to be accumulated to inform policymakers on endoscopic screening in China.With the guide of Health China 2030 Planning Outline,we have golden opportunities to promote prevention and control of GC.In this review,we summarize the characteristics of screening programs in China and other East Asian countries and introduce the past and current approaches and strategies for GC screening,aiming for featuring the latest advances and key challenges,and illustrating future visions of GC screening.Xiaohan Fan Xiangxiang Qin Yang Zhang Zhexuan Li Tong Zhou Jingying Zhang Weicheng You Wenqing Li Kaifeng Pan 2021Chinese Journal of Cancer Research2021,33,2:21

3Ultrabroad band microwave absorption from hierarchical MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)Tx hybrids via annealing treatment显示文摘Two-dimensional(2D)transition metal carbide MXene-based materials hold great potentials applied for new electromagnetic wave(EMW)absorbers.However,the application of MXenes in the field of electromagnetic wave absorption(EMA)is limited by the disadvantages of poor impedance matching,single loss mechanism,and easy oxidation.In this work,MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)hybrids were prepared by the annealing-treated Mo_(2)TiC_(2)T_(x)MXene and uniform MoO_(3)and TiO_(2)oxides in-situ grew on Mo_(2)TiC_(2)T_(x)layers.At the annealing temperature of 300℃,the minimum reflection loss(RLmin)value of MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)reaches-30.76 dB(2.3 mm)at 10.18 GHz with a significantly broadening effective absorption bandwidth(EAB)of 8.6 GHz(1.8 mm).The in-situ generated oxides creating numerous defects and heterogeneous interfaces enhance dipolar and interfacial polarizations and optimize the impedance matching of Mo_(2)TiC_(2)T_(x).Considering the excellent overall performance,the MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)hybrids can be a promising candidate for EMA.Feiyue HU Fan ZHANG Xiaohan WANG Yaya LI Hailong WANG Rui ZHANG Hongxia LI Bingbing FAN 2022Journal of Advanced Ceramics2022,11,9:5
4Orthodontic simulation system with force feedback for training complete bracket placement procedures显示文摘Background A virtual system that simulates the complete process of orthodontic bracket placement can be used for pre-clinical skill training to help students gain confidence by performing the required tasks on a virtual patient.Methods The hardware for the virtual simulation system is built using two force feedback devices to support bi-manual force feedback operation.A 3D mouse is used to adjust the position of the virtual patient.A multi-threaded computational methodology is adopted to satisfy the requirements of the frame rate.The computation threads mainly consist of the haptic thread running at a frequency of>1000Hz and the graphic thread at>30Hz.The graphic thread allows the graphics engine to effectively display the visual effects of biofilm removal and acid erosion through texture mapping.Using the haptic thread,the physics engine adopts the hierarchy octree collision-detection algorithm to simulate the multi-point and multi-region interaction between the tools and the virtual environment.Its high efficiency guarantees that the time cost can be controlled within 1 ms.The physics engine also performs collision detection between the tools and particles,making it possible to simulate paint and removal of colloids.The surface-contact constraints are defined in the system;this ensures that the bracket will not divorce from or embed into the tooth during the adjustment of the bracket.Therefore,the simulated adjustment is more realistic and natural.Results A virtual system to simulate the complete process of orthodontic bracket bonding was developed.In addition to bracket bonding and adjustment,the system simulates the necessary auxiliary steps such as smearing,acid etching,and washing.Furthermore,the system supports personalized case training.Conclusions The system provides a new method for students to practice orthodontic skills.Fan YE Luwei LIU Bin YAN Xiaohan ZHAO Aimin HAO 2021Virtual Reality & Intelligent Hardware2021,3,4:2
5Nanostructured strategies towards boosting organic lithium-ion batteries显示文摘Pursuing material development for next-generation batteries,organic electrode materials have shown great potential for lithium-ion batteries.However,their widespread adopting is plagued by intrinsic problems such as poor electronic conductivity,high dissolution inside electrolytes and unstable chemical peculiarity.Recently,nanostructured-strategies promoted organic electrodes with exotic properties for enhancing electron and ion transport together with the stability during electrochemical process,have received increasing attention and have been extensive applied in boosting the organic lithium-ion based energy storage.In this review,we summarize the applications of nanostructures to improve the performance of both organic anodes and cathodes,including(i)nanoscale design of zero-dimensional organic electrode materials,(ii)strategies of one-dimensional nanostructured organic electrode materials,(iii)construction of two-dimensional nanosized organic composite electrodes,and(iv)three-dimensional exploration of nanosized organic electrodes.We hope to stimulate high-quality applied research on understanding and handling the relationship between the nanostructure and performance of organic lithium-ion batteries that might speed up the commercialization of organic lithium ion batteries.Yujing Liu Guoyuan Sun Xiaohan Cai Fan Yang Cong Ma Min Xue Xinyong Tao 2021Journal of Energy Chemistry2021,30,3:2
6Liposoluble quinone promotes the reduction of hydrophobic mineral and extracellular electron transfer of Shewanella oneidensis MR-1显示文摘A large number of reaction systems are composed of hydrophobic interfaces and microorganisms in natural environment.However,it is not clear how microorganisms adjust their breathing patterns and respond to hydrophobic interfaces.Here,Shewanella oneidensis MR-1 was used to reduce ferrihydrite of a hydrophobic surface.Through Fe(II)kinetic analysis,it was found that the reduction rate of hydrophobic ferrihydrite was 1.8 times that of hydrophilic one.The hydrophobic surface of the mineral hinders the way the electroactive microorganism uses the water-soluble electron mediator riboflavin for indirect electron transfer and promotes MR-1 to produce more liposoluble quinones.Ubiquinone can mediate electron transfer at the hydrophobic interface.Ubiquinone-30(UQ-6)increases the reduction rate of hydrophobic ferrihydrite from 38.5±4.4 to 52.2±0.8 mM$h1.Based on the above experimental results,we propose that liposoluble electron mediator ubiquinone can act on the extracellular hydrophobic surface,proving that the metabolism of hydrophobic minerals is related to endogenous liposoluble quinones.Hydrophobic modification of minerals encourages electroactive microorganisms to adopt differentiated respiratory pathways.This finding helps in understanding the electron transfer behavior of the microbes at the hydrophobic interface and provides new ideas for the study of hydrophobic reactions that may occur in systems,such as soil and sediment.Xiaohan Lin Fan Yang Le-xing You Huan Wang Feng Zhao 2021The Innovation2021,2,2:2

8lncR-GAS5 upregulates the splicing factor SRSF10 to impair endothelial autophagy,leading to atherogenesis显示文摘Long noncoding RNAs(lncRNAs)play a critical role in the regulation of atherosclerosis.Here,we investigated the role of the lncRNA growth arrest-specific 5(lncR-GAS5)in atherogenesis.We found that the enforced expression of lncR-GAS5 contributed to the development of atherosclerosis,which presented as increased plaque size and reduced collagen content.Moreover,impaired autophagy was observed,as shown by a decreased LC3II/LC3I protein ratio and an elevated P62 level in lncR-GAS5-overexpressing human aortic endothelial cells.By contrast,lncR-GAS5 knockdown promoted autophagy.Moreover,serine/arginine-rich splicing factor 10(SRSF10)knockdown increased the LC3II/LC3I ratio and decreased the P62 level,thus enhancing the formation of autophagic vacuoles,autolysosomes,and autophagosomes.Mechanistically,lncR-GAS5 regulated the downstream splicing factor SRSF10 to impair autophagy in the endothelium,which was reversed by the knockdown of SRSF10.Further results revealed that overexpression of the lncR-GAS5-targeted gene miR-193-5p promoted autophagy and autophagic vacuole accumulation by repressing its direct target gene,SRSF10.Notably,miR-193-5p overexpression decreased plaque size and increased collagen content.Altogether,these findings demonstrate that lncR-GAS5 partially contributes to atherogenesis and plaque instability by impairing endothelial autophagy.In conclusion,lncR-GAS5 overexpression arrested endothelial autophagy through the miR-193-5p/SRSF10 signaling pathway.Thus,miR-193-5p/SRSF10 may serve as a novel treatment target for atherosclerosis.Yuhua Fan Yue Zhang Hongrui Zhao Wenfeng Liu Wanqing Xu Lintong Jiang Ranchen Xu Yue Zheng Xueqing Tang Xiaohan Li Limin Zhao Xin Liu Yang Hong Yuan Lin Hui Chen Yong Zhang 2023Frontiers of Medicine2023,17,2:1
9The Effects on the Cutting Propagation of Cinnamomum micranthum in Different Seasons显示文摘Cinnamomum micranthum is one of China Third-class Endangered Tree Species. The seedlings of C. micranthum are difficult to obtain. It is important to study the cutting propagation of C. micranthum in different seasons to improve the rooting rate for providing seedling propagation technique for the afforestation industry. In this study,the optimal season for the cutting propagation of C. micranthum was summer( May),providing 80. 6% rooting rate. The rooting rate in Summer was 33. 4% higher than that in Spring( March). This technique is important to make the best use of rare C. micranthum resources and to provide plenty of seedlings for afforestation and greening industry.Bihua CHEN Shaohua HUANG Meifang XIE Juan ZHANG Liuying CHEN Xiaohan SHE Huihua FAN Qianzhen LI 2015Asian Agricultural Research2015,7,10:1
10Review on bio-inspired polarized skylight navigation显示文摘In this review, the research progress of bio-inspired polarized skylight navigation is evaluated from the perspectives of theoretical basis, information detection, sensor design, and navigation realization. First, the theory for characterizing the polarization mode of the skylight was introduced. Second, using sunlight, moonlight, and ocean as backgrounds, the measurement results of skylight polarization distribution under different weather conditions are described to compare the variation patterns. Third, the development history and research outcomes of bionic polarization navigation sensor for polarized skylight detection and navigation information calculation are categorized into two types, namely non-imaging and imaging types. In precision measurement, the non-imaging type is higher than the imaging type, and the accuracy that it can reach is ± 0.1° of navigation accuracy without drift error. Fourth, two polarized skylight orientation algorithms,E-vector-based method and Solar Meridian-Anti Solar Meridian(SM-ASM)-based method are summarized. Fifth, this review details the combined application of polarized skylight navigation sensors and Inertial Navigation System(INS), Global Navigation Satellite System(GNSS), Vision,Simultaneous Localization and Mapping(SLAM), and other navigation systems. The yaw and trajectory accuracy can be increased by about 40% compared to classical navigation system in complex outdoor environments. Finally, the future development trends of polarization navigation are presented.Fang KONG Yingjing GUO Jianhua ZHANG Xiaojing FAN Xiaohan GUO 2023Chinese Journal of Aeronautics2023,36,9:0
11A Modified Beam Propagation Method Based on the Galerkin Method with Hermite-Gauss Basis Functions显示文摘A beam propagation method based on the Galerkin method with Hermite-Gauss basis functions for studying optical field propagation in weakly guiding dielectric structures is described. The selected basis functions naturally satisfy the required boundary conditions at infinity so that the boundary truncation is avoided. The paraxial propagation equation is converted into a set of first-order ordinary differential equations, which are solved by means of standard numerical library routines. Besides, the calculation is efficient due to its small resulted matrix. The evolution of the injected field and its normalized power along the propagation distance in an asymmetric slab waveguide and directional coupler are presented, and the solutions are good agreement with those obtained by finite difference BPM, which tests the validity of the present approach.Xiao Jinbiao Liu Xu Cai Chun Fan Hehong Sun Xiaohan 2006工程科学(英文版)2006,4,4:0
12An improved three-dimensional full-vectorial finite-difference imaginary-distance beam propagation method显示文摘A modified alternating direction implicit approach is proposed to discretize the three-dimensional full-vectorial beam propagation method (3D-FV-BPM) formulation along the longitudinal direction. The cross-coupling terms (CCTs) are neglected at the first sub- step, and then double used at the second substep. The order of two substeps is reversed for each transverse electric field component so that the CCTs are always expressed in an implicit form, thus the calculation is efficient and stable. Based on the multinomial inter- polation, a universal finite difference scheme with a high accuracy is developed to ap- proximate the 3D-FV-BPM formulation along the transverse directions, in which the dis- continuities of the normal components of the electric field across the abrupt dielectric in- terfaces are taken into account and can be applied to both uniform and non-uniform grids. The corresponding imaginary-distance procedure is first applied to a buried rectangular and a GaAs-based deeply-etched rib waveguide. The field patterns and the normalized propagation constants of the fundamental and the first order modes are presented and the hybrid nature of the full-vectorial guided-modes is demonstrated, which shows the validity and utility of the present approach. Then the modal characteristics of the deeply- and shallow-etched rib waveguides based on the InGaAsp/InGaAsP strained multiple quantum wells in InP substrate are investigated in detail. The results are necessary for modeling and the design of the planar lightwave circuits or photonic integrated circuits based on these waveguides.XIAO Jinbiao LIU Xu CAI Chun FAN Hehong SUN Xiaohan 2006Science in China(Series F)2006,49,4:0
13Preoperative Prediction of Lymph Node Metastasis in Colorectal Cancer with Deep Learning显示文摘Objective.To develop an artificial intelligence method predicting lymph node metastasis(LNM)for patients with colorectal cancer(CRC).Impact Statement.A novel interpretable multimodal AI-based method to predict LNM for CRC patients by integrating information of pathological images and serum tumor-specific biomarkers.Introduction.Preoperative diagnosis of LNM is essential in treatment planning for CRC patients.Existing radiology imaging and genomic tests approaches are either unreliable or too costly.Methods.A total of 1338 patients were recruited,where 1128 patients from one centre were included as the discovery cohort and 210 patients from other two centres were involved as the external validation cohort.We developed a Multimodal Multiple Instance Learning(MMIL)model to learn latent features from pathological images and then jointly integrated the clinical biomarker features for predicting LNM status.The heatmaps of the obtained MMIL model were generated for model interpretation.Results.The MMIL model outperformed preoperative radiology-imaging diagnosis and yielded high area under the curve(AUCs)of 0.926,0.878,0.809,and 0.857 for patients with stage T1,T2,T3,and T4 CRC,on the discovery cohort.On the external cohort,it obtained AUCs of 0.855,0.832,0.691,and 0.792,respectively(T1-T4),which indicates its prediction accuracy and potential adaptability among multiple centres.Conclusion.The MMIL model showed the potential in the early diagnosis of LNM by referring to pathological images and tumor-specific biomarkers,which is easily accessed in different institutes.We revealed the histomorphologic features determining the LNM prediction indicating the model ability to learn informative latent features.Hailing Liu Yu Zhao Fan Yang Xiaoying Lou Feng Wu Hang Li Xiaohan Xing Tingying Peng Bjoern Menze Junzhou Huang Shujun Zhang Anjia Han Jianhua Yao Xinjuan Fan 2022Biomedical Engineering Frontiers2022,3,1:0
14Global scientific trends on portal hypertension and cirrhosis in the 21st century: A bibliometric and visualized analysis显示文摘To the Editor,Cirrhosis develops histologically as regenerative nodules surrounded by fibrous bands because of chronic liver injury,resulting in portal hypertension and end‐stage liver failure.Liver cirrhosis imposes a heavy health and economic burden on many countries.In 2014,Mokdad et al.1 reported the results of the 2010 Global Burden of Disease Study(GBD).Global deaths from cirrhosis increased monotonically from just over 676,000 deaths in 1980(1.54%of global deaths)to more than 1 million deaths in 2010,or 1.95%.Portal hypertension is a group of disorders characterized by symptoms,such as hepatic encephalopathy.Cirrhosis is the main cause of portal hypertension,accounting for 80%–90%of cases.In addition,cirrhosis has fatal complications that greatly affect the quality of life of patients.Haozhuo Guo Hongbo Ni Jian Xue Fan Wang Xiaohan Sun Zhongqing Wang Meng Niu 2023Portal Hypertension & Cirrhosis2023,2,1:0
15Green rapid synthesis of Cu_(2)O/Ag heterojunctions exerting synergistic antibiosis显示文摘Semiconductor-noble metal composite has become a research focus due to its superior performance compared with its respective component.Although various methods have been developed to synthesize semiconductor-noble metal heterostructures,most of them are relatively complex multistep and use toxic reactants of high cost and risk.In this work,a series of Cu_(2)O/Ag heterojunctions were quickly prepared in one step via simple microwave-assisted green route.XRD,SEM,TEM,EDS,XPS,etc.were used to characterize obtained products,and the results indicate a Cu_(2)O/Ag metal-semiconductor heterojunction in micro-nano size was fabricated successfully.In addition,antibacterial behavior of Cu_(2)O/Ag heterojunctions against E.coli and S.aureus were investigated.Owing to the synergistic effect of Cu_(2)O and Ag,the heterojunction exhibits much better antibacterial performance than the pristine Cu_(2)O does.This work provides new insights into the green design and fabrication of surface-modified Cu_(2)O hybrid multifunctional materials for antibacterial applications.Feiyue Hu Bo Song Xiaohan Wang Shen Bao Siyang Shang Shupei Lv Bingbing Fan Rui Zhang Jingguo Li 2022Chinese Chemical Letters2022,33,1:0
16PlantcircBase 7.0:Full-length transcripts and conservation of plant circRNAs显示文摘Circular RNA(circRNA)is a special type of non-coding RNA that participates in diverse biological processes in both animals and plants.Five years ago,we developed a comprehensive plant circRNA database(PlantcircBase),which has attracted much attention from the plant circRNA community.Here,we report an updated PlantcircBase(v.7.0),which contains 171,118 circRNAs from 21 plant species.Over 31,000 of the circRNAs have full-length sequences constructed based on analysis of 749 bulk RNA sequencing(RNAseq)datasets downloaded from the public domain and Nanopore long-read sequencing results of rice RNAs newly generated in this study.A plant multiple conservation score(PMCS),based on the conservation of both sequence and expression profiles,was calculated for each circRNA to quantify and compare the conservation of all circRNAs.A new parameter,plant circRNA confidence level(PCCL),is introduced to measure the identity reliability of each circRNA based on experimental validation results and the number of references that support the circRNA.All this information and other details of circRNAs can be browsed,searched,and downloaded from PlantcircBase 7.0,which also provides online bioinformatics tools for visualization and sequence alignment.PlantcircBase 7.0 is publicly and freely accessible at http://gffzzbe43f054107d49d7h0qwfupuuuwvb6op9.ffgz.tsg.suse.edu.cn/plantcircbase/.Xiaoxu Xu Tianyu Du Weihua Mao Xiaohan Li Chu-Yu Ye Qian-Hao Zhu Longjiang Fan Qinjie Chu 2022Plant Communications2022,3,4:0
17Monolithic three-dimensional integration of aligned carbon nanotube transistors for high-performance integrated circuits显示文摘Carbon nanotube field-effect transistors(CNT FETs)have been demonstrated to exhibit high performance only through low-temperature fabrication process and require a low thermal budget to construct monolithic three-dimensional(M3D)integrated circuits(ICs),which have been considered a promising tech-nology to meet the demands of high-bandwidth computing and fully func-tional integration.However,the lack of high-quality CNT materials at the upper layer and a low-parasitic interlayer dielectric(ILD)makes the reported M3D CNT FETs and ICs unable to provide the predicted high performance.In this work,we demonstrate a multilayer stackable process for M3D integration of high-performance aligned carbon nanotube(A-CNT)transistors and ICs.A low-κ(-3)interlayer SiO_(2)layer is prepared from spin-on-glass(SOG)through processes with a highest temperature of 220℃,presenting low parasitic capaci-tance between two transistor layers and excellent planarization to offer an ideal surface for the A-CNT and device fabrication process.A high-quality A-CNT film with a carrier mobility of 650 cm 2 V^(-1)s^(-1)is prepared on the ILD layer through a clean transfer process,enabling the upper CNT FETs fabri-cated with a low-temperature process to exhibit high on-state current(1 mAμm^(-1))and peak transconductance(0.98 mSμm^(-1)).The bottom A-CNT FETs maintain pristine high performance after undergoing the ILD growth and upper FET fabrication.As a result,5-stage ring oscillators utilizing the M3D architecture show a gate propagation delay of 17 ps and an active region of approximately 100μm 2,representing the fastest and the most compact M3D ICs to date.Chenwei Fan Xiaohan Cheng Lin Xu Maguang Zhu Sujuan Ding Chuanhong Jin Yunong Xie Lian-Mao Peng Zhiyong Zhang 2023InfoMat2023,5,7:0

19Interfaces in Sulfide Solid Electrolyte‑Based All‑Solid‑State Lithium Batteries:Characterization,Mechanism and Strategy显示文摘Owing to the advantages of high energy density and environmental friendliness,lithium-ion batteries(LIBs)have been widely used as power sources in electric vehicles,energy storage systems and other devices.Conventional LIBs composed of liquid electrolytes(LEs)have potential safety hazards;thermal runaway easily leads to battery explosion and spontaneous combustion.To realize a large-scale energy storage system with higher safety and higher energy density,replacing LEs with solid-state electrolytes(SSEs)has been pursued.Among the many SSEs,sulfide SSEs are attractive because of their high ionic conductivities,easy processabilities and high thermostabilities.However,interfacial issues(interfacial reactions,chemo-mechanical failure,lithium dendrite formation,etc.)between sulfide SSEs and electrodes are factors limiting widespread application.In addition,the intrinsic interfacial issues of sulfide SSEs(electrochemical windows,diffusion mechanisms of Li^(+),etc.)should not be ignored.In this review,the behaviors,properties and mechanisms of interfaces in all-solid-state lithium batteries with a variety of sulfide SSEs are comprehensively summarized.Additionally,recent research progress on advanced characterization methods and designs used to stabilize interfaces is discussed.Finally,outlooks,challenges and possible interface engineering strategies are analyzed and proposed.Zhan Wu Xiaohan Li Chao Zheng Zheng Fan Wenkui Zhang Hui Huang Yongping Gan Yang Xia Xinping He Xinyong Tao Jun Zhang 2023Electrochemical Energy Reviews2023,6,1:0
20An advanced 2D/3D g-C_(3)N_(4)/TiO_(2)@MnO_(2) multifunctional membrane for sunlight-driven sustainable water purification显示文摘Graphitic carbon nitride(g-C_(3)N_(4))nanosheets have attracted widespread interest in the construction of advanced separation membranes.However,dense stacking and a single functionality have limited the membrane development.Here,an advanced two-/three-dimensional(2D/3D)g-C_(3)N_(4)/TiO_(2)@MnO_(2) membrane is constructed by intercalating 3D TiO_(2)@MnO_(2) nanostructures into g-C_(3)N_(4) nanosheets.The 3D flower-like nanostructures broaden the transport channels of the composite membrane.The membrane can effectively separate five oil-in-water(O/W)emulsions,with a maximum flux of 3265.67±15.01 L·m^(-2)·h^(-1)·bar^(-1) and a maximum efficiency of 99.69%±0.45%for toluene-in-water emulsion(T/W).Meanwhile,the TiO_(2)@MnO_(2) acts as an excellent electron acceptor and provides positive spatial separation of electrons–holes(e^(-)–h^(+)).The formation of 2D/3D heterojunctions allows the material with wider light absorption and smaller bandgap(2.10 eV).These photoelectric properties give the membrane good degradation of three different pollutants,with about 100%degradation for methylene blue(MB)and malachite green(MG).The photocatalytic antibacterial efficiency of the membrane is also about 100%.After cyclic experiment,the membrane maintains its original separation and photocatalytic capabilities.The remarkable multifunctional and self-cleaning properties of the g-C_(3)N_(4) based membrane represent its potential value for complex wastewater treatment.Fan Yu Chunjia Luo Xiaohan Niu Min Chao Pengfei Zhang Luke Yan 2024Nano Research2024,17,4:0
