| 1 | Effects of long-term fertilization with different substitution ratios of organic fertilizer on paddy soil显示文摘In recent years,the abuse of chemical fertilizers has caused numerous environmental problems,such as soil acidification and compaction.Replacing chemical fertilizers with organic fertilizers can effectively alleviate these problems.However,the effects of alternative organic fertilizers remain unclear.To explore the effects of organic fertilizer substitution on rice yield and paddy soil physicochemical properties and bacterial community structure,we conducted a 5-year experiment using different proportions of organic fertilizer substitution in a double-cropping rice field in Jiangxi,China.Our results showed that replacing chemical fertilizers with organic fertilizers can reduce soil acidification,increase soil organic matter content,nutrient contents,and enzyme activities,improve soil physicochemical properties and microbial community,and enhance soil metabolism.Appropriate organic substitution also had positive effects on rice production.These findings enhance our understanding of the effects of different alternative organic fertilization methods and have important theoretical significance for the promotion of the use of organic fertilizers in the future. | Weifeng SONG Aiping SHU Jiai LIU Wenchong SHI Mingcong LI Wenxue ZHANG Zuzhang LI Guangrong LIU Fusheng YUAN Shuxin ZHANG Zengbing LIU Zheng GAO | 2022 | Pedosphere2022，32，4： | 7 |
| 2 | Cylindrical vector beams reveal radiationless anapole condition in a resonant state显示文摘Nonscattering optical anapole condition is corresponding to the excitation of radiationless field distributions in open resonators,which offers new degrees of freedom for tailoring light-matter interaction.Conventional mechanisms for achieving such a condition relies on sophisticated manipulation of electromagnetic multipolar moments of all orders to guarantee superpositions of suppressed moment strengths at the same wavelength.In contrast,here we report on the excitation of optical radiationless anapole hidden in a resonant state of a Si nanoparticle utilizing a tightly focused radially polarized(RP)beam.The coexistence of magnetic resonant state and anapole condition at the same wavelength further enables the triggering of resonant state by a tightly focused azimuthally polarized(AP)beam whose corresponding electric multipole coefficient could be zero.As a result,high contrast inter-transition between radiationless anapole condition and ideal magnetic resonant scattering can be achieved experimentally in visible spectrum.The proposed mechanism is general which can be realized in different types of nanostructures.Our results showcase that the unique combination of structured light and structured Mie resonances could provide new degrees of freedom for tailoring light-matter interaction,which might shed new light on functional meta-optics. | Yudong Lu Yi Xu Xu Ouyang Mingcong Xian Yaoyu Cao Kai Chen Xiangping Li | 2022 | Opto-Electronic Advances2022，5，4： | 3 |

| 4 | Key Factors Affecting the Learning Effect of Ideological and Political Students in Colleges and Universities显示文摘In the process of ideological and political education,improving the timeliness of ideological and political education is a hot issue in theoretical research,and it has long been concerned by academic circles.This paper analyzes and discusses the factors that affect the study effect of ideological and political students in colleges and universities,which is of great theoretical and practical significance to improve the effectiveness of ideological and political education.At present,under the influence of the social environment,bad peer groups,network environment and insufficient practical and participatory teaching,ideological and political education in colleges and universities still have some problems such as weak effectiveness.In addition to the limitation of college students'social experience and the incongruity of physical and mental development,it is easy to produce negative attitudes towards ideological and political education in the age group which is prone to adverse psychology.These factors have greatly affected the effect of ideological and political education in colleges and universities. | Yingce ZHAN Qitao LI Mingcong ZHANG | 2020 | Asian Agricultural Research2020，12，5： | 1 |
| 5 | On Energy Assessment of Titanium Alloys Belt Grinding Involving Abrasive Wear Effects显示文摘Improved energy utilisation,precision,and quality are critical in the current trend of low-carbon green manufactur-ing.In this study,three abrasive belts were prepared at various wear stages and characterised quantitatively.The effects of abrasive belt wear on the specific grinding energy partition were investigated by evaluating robotic belt grinding of titanium plates.A specific grinding energy model based on subdivided tangential forces of cutting and sliding was developed for investigating specific energy and energy utilisation coefficient EUC.The surface mor-phology and Abbott–Firestone curves of the belts were introduced to analyse the experimental findings from the per-spective of the micro cutting behaviour.The specific grinding energy increased with abrasive belt wear,especially when the belt was near the end of its life.Moreover,the belt wear could lead to a predominance change of sliding and chip formation energy.The highest EUC was observed in the middle of the belt life because of its retained sharp cutting edge and uniform distribution of the grit protrusion height.This study provides guidance for balancing the energy consumption and energy utilization efficiency of belt grinding. | Mingcong Li Shudong Zhao Heng Li Yun Huang Lai Zou Wenxi Wang | 2023 | Chinese Journal of Mechanical Engineering2023，36，6： | 0 |
| 6 | Recent Progress in Optical Sensors Based on MXenes Quantum Dots and MXenes Nanosheets显示文摘In recent years,MXenes,as a new promising two-dimensional material,have received extensive attentions in the fields of environmental remediation,catalysts,sensors,and energy storage.To broaden the applications of MXenes in sensing,MXenes nanosheets(MNSs) and MXenes quantum dots(MQDs) are prepared by physical etching or chemical oxidation.MNSs are monolayered or multilayered MXenes nanosheets within several nanometers in height,and can serve as the perfect reaction substrate and fluorescence quencher.MQDs are spherical,fluorescent MXenes QDs within several nanometers in size,which possess favorable stability and photo stability.Since the distinct features such as high conductivity,favorable hydrophilicity,biocompatibility,abundant surface functional groups,and easy functionalization,MNSs and MQDs show potential applications in the fields of anti-counterfeiting,environmental monitoring,biosensing and biomedicine.This review focuses on the research of MNS s/MQDs-based optical sensors,including colorimetric sensors,fluorescence sensors,electrochemiluminescence sensors,surface plasmon resonance sensors,and surface-enhanced Raman scattering sensors.Furthermore,the current challenges and prospects concerning MNSs/MQDs-based optical sensing techniques are discussed. | Chunxiao Lin Xinhong Song Weilan Ye Ting Liu Mingcong Rong Li Niu | 2024 | Journal of Analysis and Testing2024，8，1： | 0 |
