| 1 | Timing and splitting of nitrogen fertilizer supply to increase crop yield and efficiency of nitrogen utilization in a wheat–peanut relay intercropping system in China显示文摘Agronomically optimizing the timing and rates of nitrogen(N) fertilizer application can increase crop yield and decrease N loss to the environment. Wheat(Triticum aestivum L.)–peanut(Arachis hypogaea L.) relay intercropping systems are a mainstay of economic and food security in China. We performed a field experiment to investigate the effects of N fertilizer on N recovery efficiency, crop yield, and N loss rate in wheat–peanut relay intercropping systems in the Huang-Huai-Hai Plain, China during 2015–2017. The N was applied on the day before sowing, the jointing stage(G30) or the booting stage(G40) of winter wheat, and the anthesis stage(R1) of peanut in the following percentage splits: 50-50-0-0(N1), 35-35-0-30(N2), and 35-0-35-30(N3), using 300 kg N ha-1, with 0 kg N ha-1(N0) as control. ^(15)N-labeled(20.14 atom %) urea was used to trace the fate of N in microplots. The yields of wheat and peanut increased by 12.4% and 15.4% under the N2 and N3 treatments, relative to those under the N1 treatment. The ^(15)N recovery efficiencies( ^(15)NRE) were 64.9% and 58.1% for treatments N2 and N3, significantly greater than that for the N1 treatment(45.3%). The potential N loss rates for the treatments N2 and N3 were23.7% and 7.0%, significantly lower than that for treatment N1(30.1%). Withholding N supply until the booting stage(N3) did not reduce the wheat grain yield; however, it increased the N content derived from ^(15)N-labeled urea in peanuts, promoted the distribution of ^(15)N to pods, and ultimately increased pod yields in comparison with those obtained by topdressing N at jointing stage(N2). In comparison with N2, the N uptake and N recovery efficiency(NRE) of N3 was increased by 12.0% and 24.1%,respectively, while the apparent N loss decreased by 16.7%. In conclusion, applying N fertilizer with three splits and delaying topdressing fertilization until G40 of winter wheat increased total grain yields and NRE and reduced N loss. This practice could be an environment-friendly N management strategy for wheat–peanut relay intercropping systems in China. | Zhaoxin Liu Fang Gao Yan Liu Jianqun Yang Xiaoyu Zhen Xinxin Li Ying Li Jihao Zhao Jinrong Li Bichang Qian Dongqing Yang Xiangdong Li | 2019 | The Crop Journal2019，7，1： | 12 |
| 2 | Effect of cold rolling process on microstructure and mechanical properties of high strength β titanium alloy thin sheets显示文摘The microstructure and mechanical properties of Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe high strength titanium alloy sheets prepared by unidirectional cold rolling and two-step cross cold rolling were investigated. Results showed that the β phase grains were refined significantly by cold rolling followed by solution treatment for a short time.Compared to unidirectional cold rolling, the short time solution treatment after two-step cross rolling could significantly reduce the non-uniformity of the microstructure of the alloy sheets. After aging treatment at 550 ℃,the anisotropy of the mechanical properties still existed in the unidirectional rolled sheets, and the tensile strength was highest along the rolling direction. After solution and aging treatment, the anisotropy of the mechanical properties of the two-step cross rolling process sheet was not obvious than unidirectional cold rolling,and alloy had good strength and plasticity matching. | Yan Ma Zhaoxin Du Xiaoming Cui Jun Cheng Guolong Liu Tianhao Gong Huimin Liu Xiaopeng Wang Yuyong Chen | 2018 | Progress in Natural Science:Materials International2018，28，6： | 6 |
| 3 | Role of MR-DWI and MR-PWI in the radiotherapy of implanted pulmonary VX-2 carcinoma in rabbits显示文摘Objective: To detect the activity of tumor cells and tumor blood flow before and after the radiotherapy of implanted pulmonary VX-2 carcinoma in rabbit models by using magnetic resonance diffusion-weighted imaging(MR-DWI) and magnetic resonance perfusion weighted imaging(MR-PWI), and to evaluate the effectiveness and safety of the radiotherapy based on the changes in the MR-DWI and MR-PWI parameters at different treatment stages.Methods: A total of 56 rabbit models with implanted pulmonary VX-2 carcinoma were established, and then equally divided into treatment group and control group. MR-DWI and MR-PWI were separately performed using a Philips Acheiva 1.5T MRI machine(Philips, Netherland). MRI image processing was performed using special perfusion software and the WORKSPACE advanced workstation for MRI. MRDWI was applied for the observation of tumor signals and the measurement of apparent diffusion coefficient(ADC) values; whereas MR-PWI was used for the measurement of wash in rate(WIR), wash out rate(WOR), and maximum enhancement rate(MER). The radiation treatment was performed using Siemens PRIMUS linear accelerator. In the treatment group, the radiotherapy was performed 21 days later on a once weekly dosage of 1,000 c Gy to yield a total dosage of 5,000 c Gy.Results: The ADC parameters in the region of interest on DWI were as follows: on the treatment day for the implanted pulmonary VX-2 carcinoma, the t values at the center and the edge of the lesions were 1.352 and 1.461 in the treatment group and control group(P>0.05). During weeks 0-1 after treatment, the t values at the center and the edge of the lesions were 1.336 and 1.137(P>0.05). During weeks 1-2, the t values were 1.731 and 1.736(P<0.05). During weeks 2-3, the t values were 1.742 and 1.749(P<0.05). During weeks 3-4, the t values were 2.050 and 2.127(P<0.05). During weeks 4-5, the t values were 2.764 and 2.985(P<0.05). The ADC values in the treatment group were significantly higher than in the control group. After the radiotherapy(5,000 c Gy), the tumors remarkably shrank, along with low signal on DWI, decreased signal on ADC map, and remarkably increased ADC values. As shown on PWI, on the treatment day for the implanted pulmonary VX-2 carcinoma, the t values of the WIR, WOR, and MER at the center of the lesions were 1.05, 1.31, and 1.33 in the treatment group and control group(P>0.05); in addition, the t values of the WIR, WOR, and MER at the edge of the lesions were 1.35, 1.07, and 1.51(P>0.05). During weeks 0-1 after treatment, the t values of the WIR, WOR, and MER at the center of the lesions were 1.821, 1.856, and 1.931(P<0.05); in addition, the t values of the WIR, WOR, and MER at the edge of the lesions were 1.799, 2.016, and 2.137(P<0.05). During weeks 1-1 after treatment, the t values of the WIR, WOR, and MER at the center of the lesions were 2.574, 2.156, and 2.059(P<0.05) and the t values of the WIR, WOR, and MER at the edge of the lesions were 1.869, 2.058, and 2.057(P<0.05). During weeks 2-3 after treatment, the t values of the WIR, WOR, and MER at the center of the lesions were 2.461, 2.098, and 2.739(P<0.05) and the t values of the WIR, WOR, and MER at the edge of the lesions were 2.951, 2.625, and 2.154(P<0.05). During weeks 3-4 after treatment, the t values of the WIR, WOR, and MER at the center of the lesions were 2.584, 2.107, and 2.869(P<0.05) and the t values of the WIR, WOR, and MER at the edge of the lesions were 2.057, 2.637, and 2.951(P<0.05). During weeks 4-5 after treatment, the t values of the WIR, WOR, and MER at the center of the lesions were 2.894, 2.827, and 3.285(P<0.05) and the t values of the WIR, WOR, andMER at the edge of the lesions were 3.45, 3.246, and 3.614(P<0.05). After the radiotherapy(500 c Gy), the tumors shrank on the T1 WI, WIR, WOR, and MER; meanwhile, the PWI parameter gradually decreased and reached its minimum value.Conclusions: MR-DWI and MR-PWI can accurately and directly reflect the inactivation of tumor cells and the tumor hemodynamics in rabbit models with implanted pulmonary VX-2 carcinoma, and thus provide theoretical evidences for judging the clinical effectiveness of radiotherapy for the squamous cell carcinoma of the lung. | Qiang Zhang Mingmin Zhang Zhaoxin Liu Baoqi Shi Fuliang Qi Haijiang Wang Yuan Lv Haijiao Jin Weijing Zhang | 2014 | Chinese Journal of Cancer Research2014，26，5： | 5 |

| 6 | One-step fabrication superhydrophobic sand filter for capillary-driven separation of water-in-oil emulsions显示文摘The efficient separation of water-in-oil emulsion is of significance in environment and energy filed,and it has become a world-wide challenge.Herein,we have presented a one-step,facile and low-cost approach to prepare superhydrophobic sands for efficient separation of water-in-oil emulsion.The as-prepared sand layers possessed a water contact angle higher than 151°,demonstrating their superior superhydrophobic property.Besides,the as-prepared sand layers could separate water-in-emulsions with separation efficiency up to 99.7%,which is superior to both traditional and superwettable filtration membranes.The effect of thickness of sand layer on separation performance was also investigated.The results showed that the filtration flux decreased with the increased of filtration thickness while the separation efficiency increased.The as-prepared sand layer proposed by this study is a processing candidate for separating water-in-oil emulsion in practical industry.Additionally,the as-prepared superhydrophobic sand fabrication method also provides an alternative for desert water storage. | Bao Wang Chaolang Chen Zhaoxin Li Jianfeng Wu Xianglou Liu Jiadao Wang | 2021 | Chinese Journal of Chemical Engineering2021，34，5： | 2 |
| 7 | Rolling reduction-dependent deformation mechanisms and tensile properties in aβtitanium alloy显示文摘This work investigated the dependence of deformation mechanisms and mechanical properties on cold rolling reductions of the metastable TB8 titanium alloy.Results shown that the crystal orientation of the matrix changes with the increasing level of reduction,leading to the activation of complex deformation mechanisms in the matrix.When the rolling reduction is 10%,the deformation mechanisms are dominated by dislocations and{332}<113>deformation twins.As the reductions increase to 20%-50%,the secondary deformation twinning(SDT)is triggered in primary deformation twins besides the primary kink band is activated.Meanwhile,the secondary kink bands and{332}<113>twins have be observed in the primary kink bands.When the reduction reaches to 60%,the deformation mechanisms are dominated by dislocations and deformation twins.Furthermore,the matrix refined by crisscrossing among the twins,kink bands and other deformation mechanisms during cold rolling,which shortens the dislocation mean free path and then affects the strength and shape of the alloy.The dynamic Hall-Petch effect and the interaction between multi-scale deformed structures control the work hardening behavior of the alloy. | Zhaoxin Du Qiwei He Ruirun Chen Fei Liu Jingyong Zhang Fei Yang Xueping Zhao Xiaoming Cui Jun Cheng | 2022 | Journal of Materials Science & Technology2022，，9： | 2 |
| 8 | Recycle spent graphite to defect-engineered,high-power graphite anode显示文摘Graphite is a dominant anode material for lithium-ion batteries(LIBs)due to its outstanding electrochemical performance.However,slow lithium ion(Li+)kinetics of graphite anode restricts its further application.Herein,we report that high-temperature shock(HTS)can drive spent graphite(SG)into defect-rich recycled graphite(DRG)which is ideal for high-rate anode.The DRG exhibits the charging specific capacity of 323 mAh/g at a high current density of 2 C,which outperforms commercial graphite(CG,120 mAh/g).The eminent electrochemical performance of DRG can be attributed to the recovery of layered structure and partial remaining defects of SG during ultrafast heating and cooling process,which can effectively reduce total strain energy,accelerate the phase transition in thermodynamics and improve the Li+diffusion.This study provides a facile strategy to guide the re-graphitization of SG and design high performance battery electrode materials by defect engineering from the atomic level. | Jiawei Luo Jingchao Zhang Zhaoxin Guo Zhedong Liu Shuming Dou Wei-Di Liu Yanan Chen Wenbin Hu | 2023 | Nano Research2023，16，4： | 2 |

| 18 | ITF in a coupled GCM and its interannual variability related to ENSO and IOD显示文摘The interannual variability of the mass transport of the Indonesian Throughflow (ITF) is very possible to be connected with the El Ni!o- Southern Oscillation (ENSO) in the Pacific Ocean and/or the Indian Ocean Dipole (IOD). The IPSL (Institute Pierre-Simon Laplace) coupled general circulation model (CGCM) was employed to examine the interannual variability of the ITF and understand its relationship with the climatic variation in both the basins. A 1 000 a integration was conducted and an annual mean model output was utilized. The pathways of the simulated ITF are reasonable within the Indonesian seas. The major transport occurs in the upper 300 m, with an annual mean transport of 15.68×106 m3/s, among which the 13.83×106 m3/s through the Makassar Strait is the principal component. The interannual variability of the ITF transport is significant in a 2￣4 a period. The relationship between sea level differences across the Indonesian seas (sites in the western Pacific north of the equator and south coast of Java, respectively) and the ITF transport is straightforward on the interannual time-scale with a simultaneous correlation of 0.82. Further investigation indicates that the preceding climatic variation in the tropical Pacific is related to the ITF transport anomaly. The ENSO-like pattern leads the extreme of ITF transport by 1 a, with the correlation between a Ni'o 3 SST index and the ITF transport of 0.37. It means that there tends to be an El Ni#o anomaly in the Pacific 1 a before a large ITF transport. The simultaneous correlation between the Ni$o 3 SST index and the ITF transport is -0.34. The patterns of sea surface temperature and sea surface height are, however, not the typical ENSO anomaly. The ITF transport is more related to the concurrent interannual variability over the Indian Ocean. The simultaneous correlation between the ITF transport and the dipole mode index is 0.46 and the pattern of upper layer anomaly is much like that of the IOD. | LI Wei LI Zhaoxin LIU Hailong | 2006 | Acta Oceanologica Sinica2006，25，1： | 0 |
| 19 | Pharmacokinetics of Enrofloxacin and Its Metabolite in Carp (Cyprinus carpio) After a Single Oral Administration in Medicated Feed显示文摘A precise and reliable analytical method of high performance liquid chromatography-tandem mass spectrometry(HPLCMS/MS)was developed to measure trace levels of enrofloxacin(ENR)and its major metabolite ciprofloxacin(CIP)in carp tissues.Optimized chromatographic separation was obtained on a Waters Xterra MS C_(18) reversed-phase column using gradient elution with methanol and 0.1%formic acid aqueous solution including 5mmolL^(-1) of ammonium acetate.The established method was applied to study the pharmacokinetics and distribution of ENR and CIP in tissues of carp following a single oral administration in feed at a dosage of 40mgkg^(-1) bw(body weight).Data were analyzed using DAS 2.0 dynamics software,and the experimental results suggest that ENR was rapidly absorbed and extensively distributed in carp tissues through systemic circulation,and the pharmacokinetic characteristics can be described with a two-compartment model.The elimination half-lives(t_(1/2β))from muscle,liver,gill,plasma and skin were 131,160,104,132 and 310 h,respectively.The areas under the drug concentration-time curves(AUC)for these tissues were 491,972,750,249 and 706hmgkg^(-1),respectively.The maximum concentration(C_(max))values were 13,29,37,9 and 5mgkg^(-1) with peak times(t_(max))of 8,4,4,2 and 4 h,respectively.Ciprofloxacin,the active metabolite of ENR,was also detected in carp tissues,indicating that only 1.54%of de-ethylation of ENR occurs in carp.At a water temperature of 18℃,the drug withdrawal time was determined to be no less than 24 d while the carp was fed at a single dosage of 40mgkg^(-1). | LIU Ying LI Zhaoxin ZHANG Dahai XING Lihong SUN Weihong SUN Xiaojie PENG Jixing ZHANG Yonggang LI Xianguo | 2023 | Journal of Ocean University of China2023，22，1： | 0 |
| 20 | Progress in electrode materials for the industrialization of sodium-ion batteries显示文摘In recent years,sodium-ion batteries(SIBs)have received renewed attention due to the continued rise in lithium prices.SIBs are promising to replace lithium-ion batteries under various application scenarios,such as large-scale energy storage systems and low-speed electric vehicles.As the core of SIBs,electrode materials are the key factor demining the electrochemical performance.Key drawback,including cycle stability,air stability and energy density,are refraining the development of SIBs off-industrialization.For a systematic understanding on the development of SIBs,in this review,we summarized the progress of SIBs from the industrialization viewpoint,including the fabrication methods suitable for large scale production of electrode materials of SIBs,and the optimization strategies to improve electrochemical performance.Finally,we proposed promising directions for future development of electrode materials for SIBs toward industrialization. | Zhaoxin Guo Guangdong Qian Chunying Wang Ge Zhang Ruofan Yin Wei-Di Liu Rui Liu Yanan Chen | 2023 | Progress in Natural Science:Materials International2023，33，1： | 0 |
