| 1 | Multipath structure of the typical under-ice sound channel in the Arctic:theory and experiment显示文摘Considering the typical acoustic environment of the Arctic, this paper proposes a method based on OASES-Bellhop coupled model to rapidly analyze the multipath structure of the under-ice sound channel. Firstly the proposed model refers to ice plate as stratified elastic media with some roughness. Secondly,it uses the perturbation method and Kirchhoff approximation theory to solve the scattering loss due to the sea ice inhomogeneity. Finally, the model predicts the multipath structure of the under-ice channel through Ray theory. The results of the numerical simulation and experiment indicate that the typical Arctic sound channel presents multipath structures due to the sea ice and seabed in the range of 6 km, respectively.The sea ice reflection paths are stable,with a short multipath spread within 14 ms. The seabed reflection paths have relatively weak strength. The proposed OASES-Bellhop coupled model successfully predicts the amplitude and delay of the multipath structure with small error,which indicates the proposed model is able to analyze and predict the multipath structure of the observed acoustic environment in experiment. | LIU Chonglei HUANG Haining YIN Li LIU Na WEI Chonghua LI Qihu | 2019 | Chinese Journal of Acoustics2019，38，1： | 3 |
| 2 | Effect of Adsorption of ZrO2 in Catalysts on the Efficiency of Hydrolysis of Cellulose to Sugar in Aqueous System under Microwave Radiation显示文摘Summary of main observation and conclusion Five types of ZrO2 are used to simply establish an effective aqueous catalytic system with sulfuric acid for the hydrolysis of cellulose to sugar,respectively.By adjusting surface roughness and particle size of ZrO2 dfferent adsorption is produced.Accordingy,following the thought to inhibit the self-aggregation nature of cellulose,after the introduction of ZrO2 with adsorption in catalysts,the efficiency of the hydrolysis of cellulose to sugar is improved.The results show different ZrO2 can produce different effects during the hydrolysis of the cellulose with rela-tively low crystallinity.Under the optimal conditions,the conversion of cellulose and TRS yield reaches 95.5%and 93.6%,respectively.Through this re-search,it reveals the critical point to organize a feasible and useful way for the hydrolysis of cellulose to sugar with high efficiency in an aqueous system.An important theoretical and technical support is also provided for the conversion and utiliation of cellulose in the future. | Ying Qiao Lixin Feng Zhongqiu Li Zhenyu Zhang Jing Chen Haining Na Jin Zhu Lai Chen | 2020 | Chinese Journal of Chemistry2020，38，4： | 3 |
| 3 | Glycidyl methacrylate-compatibilized poly(lactic acid)/hemp hurd biocomposites: Processing, crystallization, and thermo-mechanical response显示文摘Poly(lactic acid)-based biocomposites were developed with hemp hurd(Cannabis sativa L.) with grafting-based interfacial compatibilization. Poly(lactic acid) was extruded with hemp hurd and glycidyl methacrylate as the polymer/hurd interfacial compatibilizer, and injection molded. Interfacial compatibility between poly(lactic acid) and hemp hurd increased with grafted glycidyl methacrylate in comparison to the non-compatibilized control, as corroborated by scanning electron microscopy fractography and mechanical analysis, which showed increases in the glycidyl methacrylate-grafted 20%(w/w)hemp hurd/poly(lactic acid) biocomposite, retaining 94% of the neat polymer strength, with increases in crystallinity, and showing a range of thermo-mechanical properties desirable for rigid biocomposite applications. | Belas Ahmed Khan Haining Na Venkata Chevali Philip Warner Jin Zhu Hao Wang | 2018 | Journal of Materials Science & Technology2018，34，2： | 2 |
| 4 | Structure and Properties of PLA Composite Enhanced with Biomass Fillers from Herbaceous Plants显示文摘PLA composites containing biomass fillers from the three herbaceous plants such as reed,wheat stalk,and coco-nut fiber with length and diameter at the scale of several millimeters were prepared without using additives.The reinforcement effect on the properties of PLA/biomass filler composites is investigated.The research results show that the PLA/biomass filler composites exhibit good stiffness,flexural strength,and impact toughness.Among the three kinds of biomass fillers,reed reinforced PLA composites show optimal mechanical properties.When filled with 40%–50%reed,the flexural moduli of the composites are over 7000 MPa.Flexural strength retains at the same level of pure PLA.The notch impact strength reaches to 4.50±0.73 kJ/m^(2),which is 2.06 times higher than that of pure PLA.Furthermore,the introduction of biomass fillers increases the crystallization ability of PLA and does not increase the water absorption of the composites.This research demonstrated that PLA composites prepared with biomass fillers from the herbaceous plants(namely herb plastic composites,HPCs)is a material with good comprehensive mechanical properties while retaining the intrinsic particularity of biological sources. | Haining Na Juncheng Huang Hongguang Xu Fei Liu Liangke Xie Baoqing Zhu Jiuchen Wang Jin Zhu | 2023 | Journal of Renewable Materials2023，11，2： | 2 |
