1Maize grain concentrations and above-ground shoot acquisition of micronutrients as affected by intercropping with turnip, faba bean, chickpea, and soybean显示文摘Most research on micronutrients in maize has focused on maize grown as a monocrop. The aim of this study was to determine the effects of intercropping on the concentrations of micronutrients in maize grain and their acquisition via the shoot. We conducted field experiments to investigate the effects of intercropping with turnip (Brassica campestris L.), faba bean (Vicia faba L.), chickpea (Cicer arietinum L.), and soybean (Glycine max L.) on the iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) concentrations in the grain and their acquisition via the above-ground shoots of maize (Zea mays L.). Compared with monocropped maize grain, the grain of maize intercropped with legumes showed lower concentrations of Fe, Mn, Cu, and Zn and lower values of their corresponding harvest indexes. The micronutrient concentrations and harvest indexes in grain of maize intercropped with turnip were the same as those in monocropped maize grain. Intercropping stimulated the above-ground maize shoot acquisition of Fe, Mn, Cu and Zn, when averaged over different phosphorus (P) application rates. To our knowledge, this is the first report on the effects of intercropping on micronutrient concentrations in maize grain and on micronutrients acquisition via maize shoots (straw+grain). The maize grain Fe and Cu concentrations, but not Mn and Zn concentrations, were negatively correlated with maize grain yields. The concentrations of Fe, Mn, Cu, and Zn in maize grain were positively correlated with their corresponding harvest indexes. The decreased Fe, Mn, Cu, and Zn concentrations in grain of maize intercropped with legumes were attributed to reduced translocation of Fe, Mn, Cu, and Zn from vegetative tissues to grains. This may also be related to the delayed senescence of maize plants intercropped with legumes. We conclude that turnip/maize intercropping is beneficial to obtain high maize grain yield without decreased concentrations of Fe, Mn, Cu, and Zn in the grain. Further research is required to clarify the mechanisms underlying the changes in micronutrient concentrations in grain of intercropped maize.XIA HaiYong ZHAO JianHua SUN JianHao XUE YanFang EAGLING Tristan BAO XingGuo ZHANG FuSuo LI Long 2013Science China(Life Sciences)2013,56,9:8
2Deep reinforcement learning based energy management strategy for fuel cell/battery/supercapacitor powered electric vehicle显示文摘Vehicles using a single fuel cell as a power source often have problems such as slow response and inability to recover braking energy.Therefore,the current automobile market is mainly dominated by fuel cell hybrid vehicles.In this study,the fuel cell hybrid commercial vehicle is taken as the research object,and a fuel cell/battery/supercapacitor energy topology is proposed,and an energy management strategy based on a double-delay deep deterministic policy gradient is designed for this topological structure.This strategy takes fuel cell hydrogen consumption,fuel cell life loss,and battery life loss as the optimization goals,in which supercapacitors play the role of coordinating the power output of the fuel cell and the battery,providing more optimization ranges for the optimization of fuel cells and batteries.Compared with the deep deterministic policy gradient strategy(DDPG)and the nonlinear programming algorithm strategy,this strategy has reduced hydrogen consumption level,fuel cell loss level,and battery loss level,which greatly improves the economy and service life of the power system.The proposed EMS is based on the TD3 algorithm in deep reinforcement learning,and simultaneously optimizes a number of indicators,which is beneficial to prolong the service life of the power system.Jie Wang Jianhao Zhou Wanzhong Zhao 2022Green Energy and Intelligent Transportation2022,1,2:1

8Clock-Control Sequence Encryption Scheme and Simulation in the PCM/PPK Telemetry System显示文摘PCM/PPK telemetry system is a multi-nary pulse modulation system.It is commonly used to transmit high-accuracy time information and some express signals.To the issue of security that telemetry data is transmitted in the open space,a data encryption scheme in the PCM/PPK telemetry system is proposed.In this scheme,the PCM data of signal source are encrypted by stream cipher in which key streams are generated with clock control LSFR.The scheme can save system resource in the dual-modulation compound telemetry system.A backward key synchronization scheme is also proposed,which has the property of strong real-time and easy to implement.A simplified simulation model of PCM/PPK remote system is established based on the actual framework of telemetry system,and the model is simple and easy to simulate.The error performance of the system is analyzed in theory and tested by computer simulation.Also the security of the system is analyzed.The simulation and analysis results show that the encryption scheme can ensure the security of the telemetry data and does not cause error-diffusion.ZHAO Zemao LIU Jianhao HE Fei 2010China Communications2010,7,4:1

10Micro-interfaces modulation by UV-ozone substrate treatment for MPEA vapor fluorescence detection显示文摘Drug abuse directly endangers human health and social security,hence its sensitive and rapid detection is vitally important.In recent years,organic film-based fluorescent sensing technology has attracted more and more attention in the detection of drugs and explosives due to its advantages of simple operation and rapid detection.For film-based fluorescent sensors,in addition to sensitive materials,the surface morphology of the film is also an important factor affecting the performance.In previous studies,the regulation of surface morphology mainly depends on concentration changes or complex templates.Here,a novel fluorescent polymer probe was designed and synthesized,and a simple and efficient ultraviolet(UV)-ozone substrate treatment method is used to adjust their surface morphology.The results show that film has an excellent fluorescence enhancement effect upon exposure to methylphenethylamine(MPEA,a simulant of methamphetamine)vapor.The sensing effect of the film is significantly improved after UV-ozone substrate treatment,and the limit of detection was decreased by 10.4 times from 2.59 to 0.25 ppm.Further experiments show that the sensing performance of other fluorescent probe can also be improved by the UV-ozone substrate treatment.This convenient and general method may become a very effective approach to improve the performance of film-based fluorescent sensors.Bin Li Keke Li Wei Xu Mingzhu Yan Jianhao Zhao Wukun Zhang Mingshuai Yuan Yanyan Fu Qingguo He Jiangong Cheng 2023Nano Research2023,16,3:0
11Competitive Redox Chemistries in Vanadium Niobium Oxide for Ultrafast and Durable Lithium Storage显示文摘Niobium pentoxide(Nb_(2)O_(5))anodes have gained increasing attentions for high-power lithium-ion batteries owing to the outstanding rate capability and high safety.However,Nb2O5 anode suffers poor cycle stability even after modified and the unrevealed mechanisms have restricted the practical applications.Herein,the over-reduction of Nb5+has been demonstrated to be the critical reason for the capacity loss for the first time.Besides,an effective competitive redox strategy has been developed to solve the rapid capacity decay of Nb_(2)O_(5),which can be achieved by the incorporation of vanadium to form a new rutile VNbO_(4)anode.The highly reversible V^(3+)/V^(2+)redox couple in VNbO_(4)can effectively inhibit the over-reduction of Nb^(5+).Besides,the electron migration from V^(3+)to Nb5+can greatly increase the intrinsic electronic conductivity for VNbO4.As a result,VNbO4 anode delivers a high capacity of 206.1 mAh g^(−1)at 0.1 A g^(−1),as well as remarkable cycle performance with a retention of 93.4%after 2000 cycles at 1.0 A g^(−1).In addition,the assembled lithium-ion capacitor demonstrates a high energy density of 44 Wh kg^(−1)at 5.8 kW kg^(−1).In summary,our work provides a new insight into the design of ultra-fast and durable anodes.Xiaobo Ding Jianhao Lin Huiying Huang Bote Zhao Xunhui Xiong 2023Nano-Micro Letters2023,15,11:0
12Microwave-assisted Immobilization of Heparin onto Polyurethane Surface for Improving Blood Compatibility显示文摘Heparin was covalently immobilized onto polyurethane surface via a PEG spacer by a microwave-assisted approach to improve blood compatibility. Firstly, amino-terminated poly(ethylene glycol)(APEG) was rapidly grafted onto PU surface within 20 min by a two-step method involving microwave-assisted MDI-functionalization and subsequent microwave-assisted APEG coupling. Then, heparin was covalently immobilized through an amide linkage by the direct coupling of the carboxylic acid of heparin with the amino group of APEG on PU surface using carbodiimide coupling reaction. The surface structure and properties were characterized by X-ray photoelectron spectroscopy(XPS), atomic force microscopy(AFM) and water contact angle measurements. The results revealed that heparin-immobilized PU surface had slightly increased roughness and significantly improved hydrophilicity in comparison to the original PU surface. The anticoagulant activity of films was evaluated by whole blood clotting time(CT) and prothrombin time(PT). Complement activation was assessed by detecting complement fragment 3a concentrations of serum exposed to the films. The results revealed that the microwave-assisted heparin-immobilized PU films had excellent antithrombogenicity and suppressed complement activation, indicating improved blood compatibility.邱炳崧 MAI Weizhong 曾戎 TU Mei ZHAO Jianhao ZHA Zhengang 2014Journal of Wuhan University of Technology(Materials Science)2014,29,5:0
