| 1 | Measurement and modeling of the effective thermal conductivity for porous methane hydrate samples显示文摘The effective thermal conductivities of gas-saturated porous methane hydrates were measured by a single-sided transient plane source (TPS) technique and simulated by a generalized fractal model of porous media that based on self-similarity.The density of porous hydrate,measured by the volume of the sample in the experimental system,was used to evaluate the porosity of methane hydrate samples.The fractal model was based on Sierpinski carpet,a thermal-electrical analogy technique and one-dimensional heat flow assumption.Both the experimental and computational results show the effective thermal conductivity of methane hydrate decreases with the porosity increase.The porosity of 0.3 can reduce the thermal conductivity of the methane hydrate by 25%.By analysis of the experimental data and the simulative result,the optimized thermal conductivity of the zero-porosity methane hydrate is about 0.7 W m-1K-1. | LI DongLiang DU Jian HE Song LIANG WeiDeQing ZHAO XiangYong YANG XiangYang | 2012 | Science China Chemistry2012，55，3： | 10 |
| 2 | Gas chromatography-mass spectrometry method for determination ofβ-propiolactone in human inactivated rabies vaccine and its hydrolysis analysis显示文摘A simple method was established for the determination of β-propiolactone(BPL) in human inactivated rabies vaccine by gas chromatography-mass spectrometry(GC-MS). The determination was performed on an Agilent HP-INNOWAX(30 m ? 0.32 mm i.d., 0.25 mm) capillary column at the temperature of 80 °C.Electrospray ionization(ESI) was used by selective ion detection at m/z 42. The temperature for ESI source and inlet was set at 230 °C and 200 °C, respectively. Helium was used as the carrier gas at a flow rate of 25.1 m L/min. The total run time was 8 min. Acetonitrile and other components in the sample did not interfere with the determination of BPL. The results showed good linearity of BPL in the range of0.50–10.01 μg/mL, with the limit of detection and the limit of quantification of 0.015 μg/mL and0.050 μg/mL, respectively. Satisfactory precision was achieved for the current developed method. The method was applied to detect 6 batches of vaccine samples, and the results indicated that the target analyte BPL was present in three batches of unpurified samples, but was not detected in the purified samples, indicating the test samples were qualified. The established method was proved to be simple,versatile and sensitive, which can meet the requirements of quality control of BPL in human inactivated rabies vaccine. | Shuo Lei Xun Gao Yang Sun Xiangyong Yu Longshan Zhao | 2018 | Journal of Pharmaceutical Analysis2018，8，6： | 5 |
| 3 | Compatibility of rubber stoppers for recombinant antitumor-antivirus protein injection by gas chromatography-mass spectrometry显示文摘A simple, rapid, and sensitive gas chromatography-mass spectrometry (GC-MS) method was developed and validated for the simultaneous determination of two fatty acids, methyl hexadecanoate (MH) and methyl stearate (MS), to allow the evaluation of packaging-drug compatibility. The two migrants were quantified in selective ion-monitoring (SIM) mode, with limits of detection (LOD) of 0.0030 μg/mL and 0.0121 μg/mL. Linear calibration curves for MH and MS were obtained in the concentration ranges of 0.1011–5.0570 μg/mL and 0.2015–10.0740 μg/mL, respectively. The developed method was successfully applied to estimate the safety of the injection of recombinant antitumor-antivirus protein (RAAP). The results showed that the possible maximum daily intake was 3.0 ng and 12.1 ng for MH and MS, respectively. As these values were both below the permitted daily exposure, the migrants can be considered as having low safety risk and do not affect the quality of the injection. | Zhaorui Meng Xun Gao Haifeng Yu Lan Zhang Xiangyong Yu Longshan Zhao | 2019 | Journal of Pharmaceutical Analysis2019，9，3： | 4 |
| 4 | Three-dimensional nonlinear photonic crystal in naturally grown potassium–tantalate–niobate perovskite ferroelectrics显示文摘Since quasi-phase-matching of nonlinear optics was proposed in 1962,nonlinear photonic crystals were rapidly developed by ferroelectric domain inversion induced by electric or light poling.The three-dimensional(3D)periodical rotation of ferroelectric domains may add feasible modulation to the nonlinear coefficients and break the rigid requirements for the incident light and polarization direction in traditional quasi-phase-matching media.However,3D rotating ferroelectric domains are difficult to fabricate by the direct external poling technique.Here,we show a natural potassium-tantalate-niobate(KTN)perovskite nonlinear photonic crystal with spontaneous Rubik’s cube-like domain structures near the Curie temperature of 40℃.The KTN crystal contains 3D ferroelectric polarization distributions corresponding to the reconfigured second-order susceptibilities,which can provide rich reciprocal vectors to compensate for the phase mismatch along an arbitrary direction and polarization of incident light.Bragg diffraction and broadband second-harmonic generation are also presented.This natural nonlinear photonic crystal directly meets the 3D quasi-phase-matching condition without external poling and establishes a promising platform for all-optical nonlinear beam shaping and enables new optoelectronic applications for perovskite ferroelectrics. | Chang Li Xuping Wang Yang Wu Fei Liang Feifei Wang Xiangyong Zhao Haohai Yu Huaijin Zhang | 2020 | Light(Science & Applications)2020，9，1： | 3 |

| 14 | Structural phase transition, optical and pyroelectric properties of lead-free single crystals显示文摘0.14 at%Mn-doped 0.95(Na1/2Bi1/2)TiO3-0.05BaTiO3(0.95NBT-0.05BT)lead-free single crystals were grown by a top-seeded solution growth method(TSSG).X-ray powder diffraction measurement showed that the as-grown single crystals exhibit rhombohedral perovskite structure with apparent distortion.With the increase of temperature,successive structural phase transitions occur in the Mn-doped 0.95NBT-0.05BT single crystals.After poling,apparent dielectric anomaly is induced accompanied by the increase of the character of diffuse phase transition and the decrease of the value of dielectric constant.The Mn-doped0.95NBT-0.05BT single crystals exhibit complex domain structure,in which micro and macro domains coexist with statistically 4mm symmetry.The Mn-doped 0.95NBT-0.05BT lead-free single crystals exhibit excellent piezoelectric and pyroelectric properties,which will lead to promising advance in piezoelectric and pyroelectric applications.The infrared-absorption band occurred around 630.6 cm 1can be assigned to the'stretching'normal vibration of[Na1/2Bi1/2]/Ti-O group.The three diffused Raman bands centered around 300,560 and 800 cm 1can be attributed to F2g[TiO6]bending vibration,A1g[TiO6]stretching vibration and'soft mode'mixed by bending and stretching vibrations. | FANG BiJun WANG Meng YUAN NingYi DING JianNing ZHAO XiangYong XU HaiQing LUO HaoSu | 2013 | Chinese Science Bulletin2013，58，33： | 1 |

| 16 | Dynamic event-triggered leader-follower consensus of nonlinear multi-agent systems under directed weighted topology显示文摘This paper studies the dynamic event-triggered leader-follower consensus of nonlinear multi-agent systems(MASs)under directed weighted graph containing a directed spanning tree,and also considers the effects of disturbances and leader of non-zero control inputs in the system.Firstly,a novel distributed control protocol is designed for uncertain disturbances and leader of non-zero control inputs in MASs.Secondly,a novel dynamic event-triggered control(DETC)strategy is proposed,which eliminates the need for continuous communication between agents and reduces communication resources between agents.By introducing dynamic thresholds,the complexity of excluding Zeno behavior within the system is reduced.Finally,the effectiveness of the proposed theory is validated through numerical simulation. | Wu Yue Chen Xiangyong Qiu Jianlong Hu Shunwei Zhao Feng | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，6： | 0 |
| 17 | Enhanced H_(2) permeation and CO_(2) tolerance of self-assembled ceramic-metal-ceramic BZCYYb-Ni-CeO_(2) hybrid membrane for hydrogen separation显示文摘Perovskite-type mixed protonic-electronic conducting membranes have attracted attention because of their ability to separate and purify hydrogen from a mixture of gases generated by industrial-scale steam reforming based on an ion diffusion mechanism.Exploring cost-effective membrane materials that can achieve both high H_(2) permeability and strong CO_(2)-tolerant chemical stability has been a major challenge for industrial applications.Herein,we constructed a triple phase(ceramic-metal-ceramic)membrane composed of a perovskite ceramic phase BaZr_(0.1)Ce_(0.7)Y_(0.1)Yb_(0.1)O_(3-δ)(BZCYYb),Ni metal phase and a fluorite ceramic phase CeO_(2).Under H_(2) atmosphere,Ni metal in-situ exsolved from the oxide grains,and decorated the grain surface and boundary,thus the electronic conductivity and hydrogen separation performance can be promoted.The BZCYYbNi-CeO_(2)hybrid membrane achieved an exceptional hydrogen separation performance of 0.53 mL min^(-1)cm^(-2) at 800℃ under a 10 vol% H_(2) atmosphere,surpassing all other perovskite membranes reported to date.Furthermore,the CeO_(2) phase incorporated into the BZCYYb-Ni effectively improved the CO_(2)-tolerant chemical stability.The BZCYYbNi-CeO_(2) membrane exhibited outstanding long-term stability for at least 80 h at 700℃ under 10 vol%CO_(2)-10 vol%H_(2).The success of hybrid membrane construction creates a new direction for simultaneously improving their hydrogen separation performance and CO_(2) resistance stability. | Jianqiu Zhu Jingzeng Cui Yuxuan Zhang Ze Liu Chuan Zhou Susu Bi Jingyuan Ma Jing Zhou Zhiwei Hu Tao Liu Zhi Li Xiangyong Zhao Jian-Qiang Wang Linjuan Zhang | 2023 | Journal of Energy Chemistry2023，，7： | 0 |

| 20 | Attention-Based CNN Fusion Model for Emotion Recognition During Walking Using Discrete Wavelet Transform on EEG and Inertial Signals显示文摘Walking as a unique biometric tool conveys important information for emotion recognition.Individuals in different emotional states exhibit distinct walking patterns.For this purpose,this paper proposes a novel approach to recognizing emotion during walking using electroencephalogram(EEG)and inertial signals.Accurate recognition of emotion is achieved by training in an end-to-end deep learning fashion and taking into account multi-modal fusion.Subjects wear virtual reality head-mounted display(VR-HMD)equipment to immerse in strong emotions during walking.VR environment shows excellent imitation and experience ability,which plays an important role in awakening and changing emotions.In addition,the multi-modal signals acquired from EEG and inertial sensors are separately represented as virtual emotion images by discrete wavelet transform(DWT).These serve as input to the attention-based convolutional neural network(CNN)fusion model.The designed network structure is simple and lightweight while integrating the channel attention mechanism to extract and enhance features.To effectively improve the performance of the recognition system,the proposed decision fusion algorithm combines Critic method and majority voting strategy to determine the weight values that affect the final decision results.An investigation is made on the effect of diverse mother wavelet types and wavelet decomposition levels on model performance which indicates that the 2.2-order reverse biorthogonal(rbio2.2)wavelet with two-level decomposition has the best recognition performance.Comparative experiment results show that the proposed method outperforms other existing state-of-the-art works with an accuracy of 98.73%. | Yan Zhao Ming Guo Xiangyong Chen Jianqiang Sun Jianlong Qiu | 2024 | Big Data Mining and Analytics2024，7，1： | 0 |
