| 1 | The spatial multiscale variability of heavy metals based on factorial kriging analysis: A case study in the northeastern Beibu Gulf显示文摘Factorial kriging analysis is applied to the research on the spatial multiscale variability of heavy metals in submarine. It is used to analyze the multiscale spatial structures of seven heavy metals, Ni, Cu, Zn, Pb, Cr, As and Cd in the surface sediment from the northeastern of Beibu Gulf, identify and separate spatial variations at different scales of heavy metals, and discuss the provenance of heavy metals and the influencing factors. The results show that the existence of three-scale spatial variations those consist of nugget effect, a spherical structure with range of 30 km(short-range scale) and a spherical structure with range of 140 km(long-range scale) in the linear model of coregionalization fitted. The spatial distribution features of seven heavy metals at short-range scale reflect 'spot-like' or 'stripe-like' local-scale spatial variations; the spatial distribution features of the seven heavy metals at long-range scale represent 'slice-like' regional-scale spatial variations. At local scale, Zn, Cr, Ni,Cu, Pb and Cd are derived primarily from parent materials of Hainan Island, Leizhou Peninsula and Guangxi land, whose spatial distribution characteristics are controlled by granularity of sediments, while As is influenced dominantly by human pollution components from Hainan Island and Leizhou Peninsula. At regional scale, Zn,Cr, Ni and Cu originate primarily from parent rock materials of Leizhou Peninsula and Hainan Island, secondly from Guangxi land; As originated primarily from parent rock materials from Hainan Island, secondly from Leizhou Peninsula and Guangxi land. These metals are transported and migrated with sediments dominated by the anticlockwise circulation of Beibu Gulf year-round, deposited in 'convergence center', forming the whole sedimentary pattern in direction of NWW-NNW at regional scale. The difference in distribution type between As and other metals at regional scale is mainly due to their different geochemical behavior. | ZHAO Jianru CHU Fengyou JIN Xianglong WU Qingsong YANG Kehong GE Qian JIN Lu | 2015 | Acta Oceanologica Sinica2015，34，12： | 4 |
| 2 | Emerging of two-dimensional materials in novel memristor显示文摘The rapid development of big-data analytics(BDA),internet of things(IoT)and artificial intelligent Technology(AI)demand outstanding electronic devices and systems with faster processing speed,lower power consumption,and smarter computer architecture.Memristor,as a promising Non-Volatile Memory(NVM)device,can effectively mimic biological synapse,and has been widely studied in recent years.The appearance and development of two-dimensional materials(2D material)accelerate and boost the progress of memristor systems owing to a bunch of the particularity of 2D material compared to conventional transition metal oxides(TMOs),therefore,2D material-based memristors are called as new-generation intelligent memristors.In this review,the memristive(resistive switching)phenomena and the development of new-generation memristors are demonstrated involving graphene(GR),transition-metal dichalcogenides(TMDs)and hexagonal boron nitride(h-BN)based memristors.Moreover,the related progress of memristive mechanisms is remarked. | Zhican Zhou Fengyou Yang Shu Wang Lei Wang Xiaofeng Wang Cong Wang Yong Xie Qian Liu | 2022 | Frontiers of physics2022，17，2： | 3 |
| 3 | Bionic SERS chip with super-hydrophobic and plasmonic micro/nano dual structure显示文摘Natural surface-enhanced Raman spectroscopy(SERS) chips based on plants or insects have gained increased attention due to their facile characteristics and low costs. However, such chips remain a major challenge for practical application because of poor reproducibility and stability as well as unavoidable damage to the surface structure during coating metal and uncontrolled dehydration. By using a simple wrinkling method, we develop a new route to fabricate a low-cost bionic SERS chip for practical detection. Inspired by the taro leaf, we fabricate a SERS chip with a super-hydrophobic and plasmonic micro/nano dual structure, and its structure parameters can be optimized. Compared with the natural taro-leaf SERS chip, our artificial chip exhibits Raman signals with an order of magnitude higher sensitivity(~10^(-9)M) and enhancement factor(~10~7) under the illumination of weak laser radiation, demonstrating that our SERS chip has great potential in biological detection. The excellent performances of our bionic SERS chip are attributed to a synergy of optimized micro-wrinkle and nano-nest, which is verified by experiment and simulation. We believe our bionic chip could be a promising candidate in practical application due to its merits such as simple fabricating process, optimizable structure, low cost, excellent homogeneity, high sensitivity, and stability. | FENGYOU YANG HAORAN ZHANG HUIMIN FENG JIANJIE DONG CHUANG WANG QIAN LIU | 2018 | Photonics Research2018，6，2： | 3 |
| 4 | The Impact of Regional Rainfall on Runoff of Yachi River of Guizhou显示文摘Based on monthly runoff data of Yachi River of Guizhou from April 2014 to May 2015,and monthly rainfall data of Guiyang,Xichang,Wenjiang and Chongqing weather stations from January 2007 to November 2015,the influence of temporal-spatial component of regional rainfall on monthly runoff of Yachi River was analyzed by using REOF,multiple linear regression analysis and harmonic analysis.Temporal-spatial change of monthly rainfall around Yachi River mainly contained four kinds of modes.The first mode was northwest-southeast type,and the second mode was south-north type,and the third mode was east-west mode.Temporal components of the three modes were all quasi equilibrium seasonal and interannual changes.Among them,the first and second modes had stable seasonal change,while seasonal change of the third mode was the most unstable,and drought-flood situation of season variation was easy to happen.Seasonal change form of monthly runoff in Yachi River was obviously different from regional monthly rainfall,and it was mainly affected by underlying surface topography and human activity(reservoir and hydropower station),and could not make a natural response to seasonal change of rainfall in time.The third mode of regional monthly rainfall and cycle fitting amount of had insignificant impact on monthly runoff of Yachi River,while the first mode of regional monthly rainfall and cycle fitting amount showed significantly positive correlation with monthly runoff of Yachi River.The second mode of regional monthly rainfall and cycle fitting amount had significantly negative correlation with monthly runoff of Yachi River,and Yachi River had significant water-storage regulation effect on the mode component.Yachi River did not have water-storage regulation effect on flood component of seasonal variation of regional monthly rainfall. | Yang Dongfang Wang Fengyou Wang Lin Zhang Rong Zhu Sixi | 2017 | Meteorological and Environmental Research2017，8，1： | 2 |
| 5 | Moisture-preventing MAPbI_(3) solar cells with high photovoltaic performance via multiple ligand engineering显示文摘Perovskite solar cells present one of the most prominent photovoltaic technologies,yet their stability,and engineering at the molecular level remain challenging.We have demonstrated multifunctional molecules to improve the operating stability of perovskite solar cells while depicting a high-power conversion efficiency.The multifunctional molecule 4-[(trifluoromethyl)sulphanyl]-aniline(4TA)with trifluoromethyl(-CF_(3))and aniline(-NH_(2))moieties is meticulously designed to modulate the perovskite.The-CF_(3) and-NH_(2) functional groups have strong interaction with perovskite to suppress surface defects to improve device stability,as well as obtain large crystal grains through delaying crystallization.Moreover,this-CF_(3) forms a hydrophobic barrier on the surface of the perovskite to prevent cell decomposition.Consequently,the performance of the perovskite solar cells is remarkably improved with the efficiency increased from 18.00% to 20.24%.The perovskite solar cells with multifunctional molecular maintaining 93% of their original efficiency for over 30 days(-55%humidity)in air without device encapsulation,exhibiting a high long-term stability.Moreover,the lead leakage issue of perovskite solar cells has also been suppressed by the built-in 4TA molecule,which is beneficial to environment-friendly application.Ultimately,we believe this multifunctional small molecule provides an available way to achieve high performance perovskite solar cells and the related design strategy is helpful to further develop more versatile materials for perovskite-based optoelectronic devices. | Xin Li Jinyue Du Hui Duan Haoyan Wang Lin Fan Yunfei Sun Yingrui Sui Jinghai Yang Fengyou Wang Lili Yang | 2022 | Nano Research2022，15，2： | 1 |
| 6 | Full-scale chemical and field-effect passivation:21.52% efficiency of stable MAPbI_(3) solar cells via benzenamine modification显示文摘Organic-inorganic metal halide perovskite solar cells have achieved high efficiency of 25.5%.Finding an effective means to suppress the formation of traps and correlate stability losses are thought to be a promising route for further increasing the photovoltaic performance and commercialization potential of perovskite photovoltaic devices.Herein,we report a facile passivation model,which uses a multi-functional organic molecule to simultaneously realize the chemical passivation and field-effect passivation for the perovskite film by an upgraded anti-solvent coating method,which reduces the trap states density of the perovskite,improves interface charge transfer,and thus promotes device performance.In addition,the hydrophobic groups of the molecules can form a moisture-repelling barrier on the perovskite grains,which apparently promotes the humidity stability of the solar cells.Therefore,the optimal power conversion efficiency(PCE)of perovskite solar cells after synergistic passivation reaches 21.52%,and it can still retain 95%of the original PCE when stored in-40%humidity for 30 days.Our findings extend the scope for traps passivation to further promote both the photovoltaic performance and the stability of the perovskite solar cells. | Fengyou Wang Meifang Yang Yuhong Zhang Jinyue Du Shuo Yang Lili Yang Lin Fan Yingrui Sui Yunfei Sun Jinghai Yang | 2021 | Nano Research2021，14，8： | 1 |

Results show that ecosystem segmentation and composition are actually its space segmentation and composition,and time change decides change and succession of any ecosystems. Via temporal-spatial change of ecosystem and segmentation and composition,change and succession trend of ecosystem and future development are determined,which lays foundation for analyzing structure and composition of earth ecosystem. | Yang Dongfang Wang Fengyou He Huazhong Zhu Sixi Wu Yunjie | 2014 | Meteorological and Environmental Research2014，5，10： | 1 |
| 8 | Earth Ecosystem Theory: Ⅲ Structure and Interface显示文摘By applying the segmentation and composition principles of ecosystem,the structure and interface of earth ecosystem are fully elaborated,and corresponding model diagrams are established to display its composition and interconversion. The research finds that earth ecosystem includes three sub-ecosystems: terrestrial ecosystem,marine ecosystem and atmospheric ecosystem. The impact sequence of sub-ecosystems on earth ecosystem is atmospheric ecosystem > marine ecosystem > terrestrial ecosystem. Based on the segmentation and composition principles of ecosystem and the application of earth ecosystem structure and interface,we give new explanations to Taoism and Taiji with the eight diagrams,which contributes to theoretical research of natural science. | Yang Dongfang Wang Fengyou Wu Youfu He Huazhong Zhu Sixi | 2014 | Meteorological and Environmental Research2014，5，11： | 0 |
| 9 | Effects of PHC on Water Quality of Jiaozhou Bay Ⅴ.Water Transfer Process显示文摘Based on the investigation data of PHC content in Jiaozhou Bay,China during 1980-1981,the vertical distribution of PHC content in the water of Jiaozhou Bay was analyzed.The results showed that from 1980 to 1981,the vertical distribution of PHC content in the water of Jiaozhou Bay depended on the water transfer process of PHC.During the water transfer process of PHC,PHC was input from pollution sources into the surface water of the bay firstly,and then it settled to the bottom.The horizontal distribution trends of PHC content in the surface and bottom water,the changes of PHC content in the surface and bottom water,and the vertical changes of PHC content showed that the settlement of PHC was fast and was consistent with PHC content.PHC accumulated at the bottom after continuous settlement of PHC,which revealed the water transfer process of PHC in Jiaozhou Bay. | Yang Dongfang Zhu Sixi Wang Fengyou Wang Ming Yang Xiuqin | 2016 | Meteorological and Environmental Research2016，7，4： | 0 |
| 10 | All-atomristor logic gates显示文摘The atomristor(monolayer two-dimensional(2D)-material memristor)is competitive in high-speed logic computing due to its binary feature,lower energy consumption,faster switch response,and so on.Yet to date,all-atomristor logic gates used for logic computing have not been reported due to the poor consistency of different atomristors in performance.Here,by studying band structures and electron transport properties of MoS2 atomristor,a comprehensive memristive mechanism is obtained.Guided by the simulation results,monolayer MoS2 with moderated defect concentration has been fabricated in the experiment,which can build atomristors with high performance and good consistency.Based on this,for the first time,MoS2 all-atomristor logic gates are realized successfully.As a demonstration,a half-adder based on the logic gates and a binary neural network(BNN)based on crossbar arrays are evaluated,indicating the applicability in various logic computing circumstances.Owing to shorter transition time and lower energy consumption,all-atomristor logic gates will open many new opportunities for next-generation logic computing and data processing. | Shu Wang Zhican Zhou Fengyou Yang Shengyao Chen Qiaoxuan Zhang Wenqi Xiong Yusong Qu Zhongchang Wang Cong Wang Qian Liu | 2023 | Nano Research2023，16，1： | 0 |
| 11 | Effects of PHC on Water Quality of Jiaozhou Bay Ⅵ.Transfer Laws显示文摘According to the investigation data of PHC content in Jiaozhou Bay,China from 1979 to 1983,the content,sources,horizontal,vertical and seasonal distribution,and transfer laws of PHC in the water of the bay were analyzed on spatial scale,and the processes of pollution sources,land transfer,sedimentation,and water transfer of PHC in Jiaozhou Bay were discussed on temporal scale. These laws and changing processes could provide theoretical foundation for studies on water transfer of PHC and other heavy metals. | Yang Dongfang Wang Fengyou Zhu Sixi Long Mingzhong Yang Xiuqin | 2016 | Meteorological and Environmental Research2016，7，5： | 0 |
| 12 | Petrogenesis and tectonic implication of lavas from the Yap Trench,western Pacific显示文摘We present major and trace element data of lava recovered from the northern Yap Trench in the western Pacific and discuss their petrogenesis and tectonic implications within the framework of interactions between the Caroline Ridge and Yap Trench.Rocks were collected from both landward and seaward trench slopes and exhibited geochemical characteristics similar to backarc basin basalt(BABB)and mid-ocean ridge basalt(MORB),including high Fe content,tholeiitic affinity,high TiO_(2) value at a given FeO_(T)/MgO ratio,Ti/V ratio between 20 and50,low Ba/Nb ratio and Th/Nb ratio,and trace element patterns commonly displayed by BABB and MORB,which are distinct from arc lava.These rocks seem to have been generated during mantle upwelling and decompression melting at a spreading center.However,compared with typical forearc lava produced by seafloor spreading in the Mariana forearc region,such as the early Eocene forearc basalts and late Neogene forearc lava in the southernmost Mariana Trench,the Yap Trench lava is derived from a more fertile mantle and feature a more minor subduction component;thus,they cannot be the products of forearc mantle decompression melting.We suggest that the landward slope lava represents backarc basin crust that was overthrust onto the forearc lithosphere during the collision of the Caroline Ridge with the Yap Trench(20–25 Ma),which played a key role in the evolution of the Yap subduction system.Moreover,the seaward slope lava represents the subduction plate crust that accreted onto the deep trench during the collision.This collision event resulted in the cessation of Yap Arc magmatism;thus,the Yap Trench volcanic rocks(<25 Ma)previously suggested to be arc magma products may actually represent the nascent island arc lava with a lower subduction component than in the mature Mariana Arc lava. | Ling Chen Limei Tang Jichao Yang Xiaohu Li Wei Wang Fengyou Chu Jie Zhang | 2021 | Acta Oceanologica Sinica2021，40，11： | 0 |
| 13 | Petrology and geochemistry of cold seep carbonates from the northern Okinawa Trough,East China Sea:implications to early diagenesis显示文摘Carbonate samples were collected from the northern Okinawa Trough in the East China Sea in 2013.The petrology,mineralogy,carbon and oxygen isotopes,and rare earth elements(REEs)of these samples were analyzed.Aragonite,high-Mg calcite,and dolomite were the main carbonate minerals,the contents of which varied greatly among the carbonate samples.Petrological observations revealed the common occurrence of framboidal pyrites.Theδ^(13)C values of carbonates varied from-53.7‰to-39.3‰(average of-47.3‰based on Vienna Pee Dee Belemnite(V-PDB),n=9),and theδ^(18)O values ranged from 0.6‰to 3.4‰(average of 1.9‰;V-PDB,n=9).The carbon and oxygen isotope characteristics indicated that the carbonates precipitated during the anaerobic oxidation of methane.The carbon source was a mixture of thermogenic methane and biogenic methane,possibly with a greater contribution from the former.The oxygen isotope data showed that gas hydrate dissociation occurred during carbonate precipitation.The Ce anomalies suggested that the carbonates precipitated in an anoxic environment.A slight enrichment of middle REEs(MREEs)could be attributable to the early diagenesis.The structures,minerals,oxygen isotopes,and MREEs all indicated that the carbonates experienced some degree of early diagenesis.Therefore,the infl uence of early diagenesis should be considered when using geological and geochemical proxies to reconstruct original methane seepage environments. | Kehong YANG Zhimin ZHU Yanhui DONG Weiyan ZHANG Fengyou CHU | 2022 | Journal of Oceanology and Limnology2022，40，4： | 0 |
| 14 | Jiaozhou Bay and Surrounding Waters not Polluted by Cr显示文摘Based on the investigation data of water area in Jiaozhou Bay in April and August of 1981,Cr content and its surface horizontal distribution in water area of Jiaozhou Bay were studied. Research results showed that Cr content in the water body of Jiaozhou Bay was between 0. 18 and 32.32μg/L,corresponding with national class-one seawater quality standard( 50. 00μg/L). The water area of Jiaozhou Bay was not polluted by any Cr. In April,Cr content was higher in northeast water area of Jiaozhou Bay and lower in southern coastal waters. In August,Cr content was lower in whole Jiaozhou Bay. Cr in water area of Jiaozhou Bay was mainly from river,which was between 1. 85 and 32. 32 μg/L. It showed that Cr content of river transportation was lower,and river was not polluted by Cr,and water quality was all very clean from river to all marine coastal waters and gulf waters. | Yang Dongfang Wang Fengyou Zhu Sixi He Huazhong Wu Youfu | 2017 | Meteorological and Environmental Research2017，8，4： | 0 |
| 15 | Temporal-spatial Change of Cr Content in Bottom Waters显示文摘Based on the investigation data of Jiaozhou Bay waters in 1981,current situation and horizontal distribution of Cr content in bottom waters of Jiaozhou Bay mouth were studied. Results showed that in bottom waters of Jiaozhou Bay center,Cr content changed from 0. 50 to3. 78 μg/L in April. In August,Cr content changed from 0. 14 to 1. 42 μg/L in bottom waters of Jiaozhou Bay mouth. It showed that Cr content corresponded with national class-one seawater quality standard(50. 00 μg/L) at different times and spaces,and Cr content was far less than5. 00 μg/L. Therefore,under the effect of vertical water body,water quality was clean in bottom waters of Jiaozhou Bay,which was not polluted by Cr. In bottom waters of Jiaozhou Bay center in April and bottom waters of Jiaozhou Bay mouth in August,Cr transported by the river came to the bottom layer from surface layer by passing through water body in temporal-spatial change process. Under the effects of gravity and water flow,Cr continuously and quickly sank to the sea bottom. It verified the sedimentation process of Cr content. | Yang Dongfang Zhu Sixi Wang Fengyou Yang Xiuqin Zhao Xiaoli | 2017 | Meteorological and Environmental Research2017，8，5： | 0 |
| 16 | As Sources in Jiaozhou Bay Waters显示文摘Based on data from the investigation in Jiaozhou Bay waters in 1982,the distribution,transfer and seasonal variation of As in Jiaozhou Bay were analyzed. Research results showed that in Jiaozhou Bay,As content was 0. 22-2. 80 μg /L at surface layer in one year and 0. 84-4. 48 μg /L at bottom layer. In one year,there was no As pollution in the whole waters of Jiaozhou Bay,and only low-content As was input into Jiaozhou Bay. By the horizontal distribution in the waters,it was able to determine if the mater was transported from the land into the waters and what the way of the transportation was. In April and October,there was no As source in the bay; the As content came from the river transportation in June and from the surface runoff transportation in July. In the land transfer process,the As content change in waters of Jiaozhou Bay was determined by the rainy season. There was no pollution of As in the soils and waters around the bay,so the As content was very low in the rivers around the bay.In the waters transfer process,in July and October,if there was the As source in the waters of Jiaozhou Bay or not,the bottom area with the highcontent As was formed in the bay center. | Yang Dongfang Zhu Sixi Wang Fengyou He Huazhong Wu Qingjie | 2014 | Meteorological and Environmental Research2014，5，5： | 0 |
| 17 | Effects of PHC on Water Quality of Jiaozhou Bay Ⅱ. Changing Process of Pollution Sources显示文摘Based on investigation data on PHC content in Jiaozhou Bay,China during 1979-1983,the horizontal distribution and pollution sources of PHC in Jiaozhou Bay were analyzed. The results showed that from 1979 to 1983,PHC in the water body of Jiaozhou Bay was mainly from rivers such as Haibo River,Licun River and Loushan River,and PHC content ranged from 0.10 to 1.10 mg/L. The pollution sources of PHC were serious during 1979-1981 and then became slight during 1982-1983. From 1979- 1981 to 1982-1983,PHC content,horizontal distribution and degree of pollution sources changed,but the input mode of PHC was constant,that is,PHC was brought into Jiaozhou Bay by rivers. | Yang Dongfang Wang Fengyou Zhu Sixi Long Mingzhong Yang Xiuqin | 2016 | Meteorological and Environmental Research2016，7，1： | 0 |
| 18 | Settlement Area of Cr Content Decided by Source and Topographic Features显示文摘Based on the investigation data of Jiaozhou Bay waters in 1981,change range,horizontal distribution and vertical change of Cr content in surface and bottom waters of Jiaozhou Bay were studied. The results showed that at change scale,Cr contents from surface and bottom layers had same change range in Jiaozhou Bay waters of August; at space scale,Cr contents from surface and bottom layers had converse change trend;at vertical scale,Cr contents from surface and bottom layers had similar change. At regional scale,Cr content from surface layer was more than that from bottom layer in Jiaozhou Bay waters except stations A3 and A6; at stations A6 and A3,Cr content from surface layer was less than that from bottom layer. It illustrated that high settlement area of bottom Cr content was in estuary of Haibo River and sunken waters of bay mouth.Therefore,the source and special topographic features decided high settlement area of Cr content in Jiaozhou Bay waters. | Yang Dongfang Zhu Sixi Wang Zhikang Yang Xiuqin Wang Fengyou | 2017 | Meteorological and Environmental Research2017，8，6： | 0 |
| 19 | Earth Ecosystem Theory: I Theoretical System显示文摘Earth is the place of human existence and life. Without the earth,there is no human,no nature either. To study human existence,the earth of human living is firstly studied. By the study of many natural phenomena on the earth,we firstly put forward the theory of earth ecosystem,expound its definition,structure,aim,function,content and significance,and illustrate the characteristics of earth ecosystem. So we found the theory of earth ecosystem,and unveil the variable processes and the operation mechanisms of earth ecosystem. We put forward the earth ecosystem and its theoretic system,which are different from the previous ' earth system science' and ' Gaia hypothesis'. We consider that among each part of the environment,between environment and organism,there are organic,close and coalescent relationships,so that the earth ecosystem is able to have a sustainable development. Even if there is no life,the earth ecosystem also can control and regulate the earth changes,and possesses the stable state. Therefore,the foundation of the earth ecosystem theory is conducive to the studies of the global problems: the change processes and trends of resources,ecologies,environments,disasters,and so on. | Yang Dongfang Wang Fengyou Zhu Sixi He Huazhong Wu Yunjie | 2014 | Meteorological and Environmental Research2014，5，9： | 0 |
| 20 | Effects of PHC on Water Quality of Jiaozhou Bay Ⅰ. Annual Variation of PHC Content显示文摘Based on investigation data on PHC in Jiaozhou Bay,China from 1979 to 1983,the monthly,seasonal and annual variations of PHC content in Jiaozhou Bay were studied.The results showed that from 1979 to 1983,Jiaozhou Bay was polluted by PHC seriously and then slightly in spring and summer,while Jiaozhou Bay was polluted by PHC slightly in autumn.During 1979-1983,PHC content in the water body of Jiaozhou Bay decreased year by year,and it was close to the background value gradually.Moreover,the reduction was obvious in spring and summer but very slight in autumn.Therefore,the water quality of Jiaozhou Bay became better. | Yang Dongfang Wang Fengyou Zhu Sixi Yang Xiuqin Long Mingzhong | 2015 | Meteorological and Environmental Research2015，6，11： | 0 |
