| 3 | A biobased flame retardant towards improvement of flame retardancy and mechanical property of ethylene vinyl acetate显示文摘A new biobased flame retardant(MHPA)with remarkable compatibility was synthesized via a facile and low-cost neutralization reaction of magnesium hydroxide(MH)and phytic acid(PA).By blending the prepared MHPA into ethylene vinyl acetate(EVA),the fire retardancy,smoke suppression and mechanical properties of the composites were significantly improved.When 50 wt%of MH was added into EVA matrix,the value of limiting oxygen index(LOI)reached 26.1%.Whereas,when 10 wt%MH in the EVA composites(with initial 50 wt%MH)was replaced by MHPA,the resulted EVA composites had a LOI value of 30.8%,indicating high efficiency of addition of MHPA to improve flame retardancy.Moreover,the heat release rate(HRR)and total smoke production(TSP)of the EVA composites reduced by 54.4%and 27.6%,respectively,suggesting that incorporation of MHPA could effectively hinder rapid degradation of EVA composites during burning process.The fire-retardant mechanism may reside in that the MHPA combined with MH can present the excellent carbonization and expansion effects.This study illustrates that the biobased MHPA has a broad application prospect to develop flame-retardant EVA composites. | Siyi Xu Yue Han Cheng Zhou Jianxi Li Liguo Shen Hongjun Lin | 2023 | Chinese Chemical Letters2023，34，1： | 1 |
| 4 | Geochemistry and Petrogenesis of Volcanic Rocks from the Continent-Ocean Transition Zone in Northern South China Sea and Their Tectonic Implications显示文摘Miocene–Pliocene(22–5 Myr) volcanism and associated seamounts are abundant in the continent-ocean transition(COT) zone in the margin of the north South China Sea(SCS). The petrogenesis of volcanic rocks from these seamounts and regional tectonic evolution of COT zone are poorly known. In this paper, we obtained whole-rock major and trace element compositions and Sr-Nd-Pb isotopic data for these volcanic rocks from the Puyuan and Beipo seamounts within COT zone, in northeastern SCS. Based on the geochemical analyses, the volcanic rocks are classified as alkaline ocean island basalts(OIB) and enriched mid-ocean ridge basalts(E-MORB). The OIBs from the Puyuan seamount are alkaline trachybasalts and tephrites that show enrichment of the light rare earth elements(LREE) relative to heavy rare earth elements(HREE) and more radiogenic Sr-Nd isotopic compositions, and have significant ‘Dupal isotopic anomaly'. In contrast, the E-MORBs from the Beipo seamount are tholeiitic basalts that have less enrichment in LREE and less radiogenic Sr-Nd isotopic compositions than the counterparts from the Puyuan seamount. Petrological and geochemical differences between the OIBs and MORBs from these two seamounts can be explained by different mantle sources and tectonic evolution stages of the COT zone. Syn-spreading OIB type basalts from the Puyuan seamount were derived from an isotopically ‘enriched', and garnet facies-dominated pyroxenitic mantle transferred by the Hainan mantle plume. In contrast, post-spreading E-MORB type basalts from the Beipo seamount are considered to be derived from the melting of isotopically ‘depleted' pyroxenite mantle triggered by lithosphere bending and subsequent post-rifting at the lower continental slope of the northern margin. | XU Yue YANG Yaoming YU Hongjun GAO Wei GAO Xiangxing LIU Baohua TIAN Xu YANG Jichao ZHANG Wenquan | 2020 | Journal of Ocean University of China2020，19，5： | 1 |

| 6 | Automatic Monitoring of Chilling Requirement for Sweet Cherry and Its Application in Protected Cultivation显示文摘For sweet cherry,the economic benefit of protected cultivation is much higher than that of open field cultivation. However,problems such as nonuniform germination,aberrant flower,abortion,bad fruit setting and delayed maturation appear frequently due to the inaccurate regulation of chilling requirement. In order to solve the problems,an automatic system for monitoring,selecting and recording of chilling requirement in protected cultivation of sweet cherry was designed and developed. The system,which consisted of temperature detection,effective chilling temperature selection,signal conversion and output and chilling accumulation display,had been continuously used in protected cultivation of sweet cherry for 3 years and good effects had been achieved. The system monitored chilling accumulation accurately and made it more reasonable for the time selection of greenhouse covering,thus avoiding risks of nonuniform germination,bad fruit setting and delayed maturation,etc. Under the coordinate application of this system with other modern measuring and controlling techniques such as automatic detection and alarming of temperature and humidity,the environment in greenhouses was regulated precisely that the uniform fruits were obtained and the expected yield,quality and harvest time were achieved. | Daohui ZHANG Hongjun ZHAO Hechun GAO Yue TAN Jiawei WANG Xin CHEN Hairong WEI Qing-zhong LIU | 2016 | Agricultural Biotechnology2016，5，3： | 1 |
| 7 | Room-temperature synthesis of layered open framework cathode for sodium-ion batteries显示文摘The synthesis of active electrode materials at room temperature is one of the effective strategies to reduce the fabrication cost of sodium ion batteries(SIBs).Herein,a layered material(Na_(2)[(VO)_(2)(HPO_(4))_(2)C_(2)O_(4)]·2H_(2)O,abbreviated as NVPC followingly)with open-framework structures has been successfully prepared at room temperature under ambient conditions and is evaluated as a cathode for SIBs.It is revealed that NVPC cathode can deliver a maximum reversible capacity of ca.70 mAh/g at 10 mA/g,and exhibit superior rate capability and cycling performance:at 50 mA/g,maximum reversible capacity ca.50 m Ah/g with capacity retention of 88.4%over 250 cycles corresponds to only 0.046%capacity decay per cycle;at 100 mA/g,a maximum reversible capacity of 35 mAh/g with capacity retention of60.9%over 500 cycles.This study demonstrates a practical example of a low-cost synthesis of the cathode materials for SIBs.At the same time,the systematic electrochemical research results also show promising prospects for long lifespan low-cost SIBs. | Ruding Zhang Huixin Chen Hongjun Yue | 2023 | Chinese Chemical Letters2023，34，5： | 0 |

| 9 | Reversible potassium storage in ultrafine CF_(x): A superior cathode material for potassium batteries and its mechanism显示文摘Current studies of cathodes for potassium batteries(PBs) mainly focus on the intercalation-type materials.The conversion-type materials that possess much higher theoretical capacities are rarely discussed in previous literatures.In this work,carbon fluoride(CF_x) is reported as a high capacity conversion-type cathode for PBs for the first time.The material delivers a remarkable discharge capacity of>250 mAh g^(-1) with mid-voltage of 2.6 V at 20 mA g^(-1).Moreover,a highly reversible capacity of around 95 mAh g^(-1) is achieved at 125 mA g^(-1) and maintained for 900 cycles,demonstrating its excellent cycling stability.The mechanism of this highly reversible conversion reaction is further investigated by nuclear magnetic resonance spectra,X-ray diffraction,and transmission electron microscopy studies.According to the analyses,the C-F bond in the cycled material is different from that in the pristine state,which presents relatively higher reversibility.This finding offers important insights for further improving the performance of the CF_x.This work not only demonstrates the CF_x as a high performance cathode for PBs,but also paves a new avenue of exploring conversion-type cathodes for high energy density PBs. | Hongjun Yue Huixin Chen Chen Zhao Zhiming Zheng Ke Zhou Qjaobao Zhang Guiming Zhong Can-Zhong Lu Yong Yang | 2021 | Journal of Energy Chemistry2021，30，2： | 0 |
| 10 | Deciphering the potassium storage phase conversion mechanism of phosphorus by combined solid-state NMR spectroscopy and density functional theory calculations显示文摘Phosphorus is the potential anode material for emerging potassium-ion batteries(PIBs)owing to the highest specific capacity and relatively low operation plateau.However,the reversible delivered capacities of phosphorus-based anodes,in reality,are far from the theoretical capacity corresponding to the formation of K3P alloy.And,their underlying potassium storage mechanisms remain poorly understood.To address this issue,for the first time,we perform high-resolution solid-state31P NMR combined with XRD measurements,and density functional theory calculations to yield a systemic quantitative understanding of(de)potassiation reaction mechanism of phosphorus anode.We explicitly reveal a previously unknown asymmetrical nanocrystalline-to-amorphous transition process via rP←→(K_(3)P_(11),K_(3)P_(7),beta-K_(4)P_(6))←→(alpha-K4P6)←→(K_(1-x)P,KP,K_(4-x)P3,K_(1+x)P)←→(amorphous K4P3,amorphous K3P)that are proceed along with the electrochemical potassiation/depotassiation processes.Additionally,the corresponding KP alloys intermediates,such as the amorphous phases of K_(4)P_(3),K_(3)P,and the nonstoichiometric phases of“K_(1-x)P”,“K_(1+x)P”,“K_(4-x)P_(3)”are experimentally detected,which indicating various complicated K-P alloy species are coexisted and evolved with the sluggish electrochemical reaction kinetics,resulting in lower capacity of phosphorus-based anodes.Our findings offer some insights into the specific multi-phase evolution mechanism of alloying anodes that may be generally involved in conversion-type electrode materials for PIBs. | Huixin Chen Lingyi Meng Hongjun Yue Chengxin Peng Qiaobao Zhang Guiming Zhong Ding Chen | 2023 | Journal of Energy Chemistry2023，，4： | 0 |

| 12 | Wireless Self-Powered Vibration Sensor System for Intelligent Spindle Monitoring显示文摘In recent years,high-end equipment is widely used in industry and the accuracy requirements of the equipment have been risen year by year.During the machining process,the high-end equipment failure may have a great impact on the product quality.It is necessary to monitor the status of equipment and to predict fault diagnosis.At present,most of the condition monitoring devices for mechanical equipment have problems of large size,low precision and low energy utilization.A wireless self-powered intelligent spindle vibration acceleration sensor system based on piezoelectric energy harvesting is proposed.Based on rotor sensing technology,a sensor is made to mount on the tool holder and build the related circuit.Firstly,the energy management module collects the mechanical energy in the environment and converts the piezoelectric vibration energy into electric energy to provide 3.3 Vfor the subsequent circuit.The lithium battery supplies the system with additional power and monitors’the power of the energy storage circuit in real-time.Secondly,a three-axis acceleration sensor is used to collect,analyze and filter a series of signal processing operations of the vibration signal in the environment.The signal is sent to the upper computer by wireless transmission.The host computer outputs the corresponding X,Y,and Z channel waveforms and data under the condition of the spindle speed of 50∼2500 r/min with real-time monitoring.The KEIL5 platform is used to develop the system software.The small-size piezoelectric vibration sensor with high-speed,high-energy utilization,high accuracy,and easy installation is used for spindle monitoring.The experiment results show that the sensor system is available and practical. | Lei Yu Hongjun Wang Yubin Yue Shucong Liu Xiangxiang Mao Fengshou Gu | 2023 | Structural Durability & Health Monitoring2023，17，4： | 0 |
| 13 | Hot Deformation Behaviors in Ti-6Al-4V/(TiB+TiC)Composites显示文摘Thermal compression testing was investigated using the Gleeble 3800 thermal simulator,and thermal deformation behavior of particle-reinforced titanium matrix composites(TMCs)was studied under deformation temperatures of 750-900°C,strain rates of 0.001-1 s^(-1),and experimental deformation of 60%.According to obtained flow stress curves,the hot deformation characteristics were analyzed.Based on the Arrhenius hyperbolic sinusoidal model,the constitutive equation at high temperature was established.Based on the theory of dynamic material models,a hot processing map of TMCs at high temperature was established,and the peak region of power dissipation rate and the instability region in the hot processing map were both determined.At the same time,the corresponding microstructures in the peak power dissipation rate and rheological instability regions were observed.The results showed that flow stress decreased with increasing deformation temperature and increased with increasing strain rate.The thermal deformation activation energy of titanium matrix composites was 301.8 kJ/mol.The Ti-6Al-4V/(TiB+TiC)composites possessed only one instability zone under high-temperature compression at a strain of 0.5,with corresponding temperatures at 750-840°C and strain rates at 0.1-1 s^(-1).The optimal thermal deformation parameters included corresponding temperatures of 830-880°C and strain rates of 0.001-0.05 s^(-1).The microstructures corresponding to optimal hot working parameters in processing maps were more homogeneous than the microstructures in the instability zone,including the distribution uniformity of reinforcement and the degree of dynamic recrystallization,and no instability phenomena including abnormal grain growth,microcracks or intensive fracture of reinforcements were found,indicating that the hot processing map had a positive guiding effect on the option of desirable material thermal-working parameters. | Xuejian Lin Hongjun Huang Fuyu Dong Yue Zhang Xiaoguang Yuan Bowen Zheng Xiaojiao Zuo | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，12： | 0 |
| 14 | Magnetic properties indicate the sources of hadal sediments in the Yap Trench,northwest Pacific Ocean显示文摘Magnetic minerals in marine sediments are often masked by the primary natural remanent magnetization and material source signals.In order to understand sedimentary environment and sources of sediments in the abyss,we studied 126 samples of five bottom surface cores collected by the Jiaolong Submersible at 4000-7000 m in depth during the third stage of the China's 38th Ocean Voyage.The magnetic properties of the sediments were analyzed using Thermosusceptibility(k-T)curves and Day plot.The results show that the magnetic minerals in the sediments of the Yap Trench are mainly maghemite,and the overall magnetic and soft magnetic properties were strong.The magnetic particles of sediments are dominated by pseudo single domains(PSD)grains.The main source of sediment is locally-derived basalt debris and volcanic debris,and the process of sedimentation is gravity-like flow deposition. | CHEN Yu YANG Jichao DADA Olusegun A YANG Yaomin LIN Zhen CUI Zhen XU Yue YU Hongjun LIU Baohua | 2020 | Journal of Oceanology and Limnology2020，38，3： | 0 |
