| 1 | The effect of an electric field on the thermomechanical damage of nodular defects in dielectric multilayer coatings irradiated by nanosecond laser pulses显示文摘Thermomechanical damage of nodules in dielectric multilayer coatings that are irradiated by nanosecond laser pulses has been interpreted with respect to mechanical properties and electric-field enhancement.However,the effect of electric-field enhancement in nodular damage,especially the influence of electric-field distributions,has never been directly demonstrated through experimental results,which prevents the achievement of a clear understanding of the damage process of nodular defects.Here,a systematic and comparative study was designed to reveal how electric-field distributions affect the damage behavior of nodules.To obtain reliable results,two series of artificial nodules with different geometries and film absorption characteristics were prepared from monodisperse silica microspheres.After establishing simplified geometrical models of the nodules,the electric-field enhancement was simulated using a three-dimensional finite-difference time-domain code.Then,the damage morphologies of the artificial nodules were directly compared with the simulated electric-field intensity profiles.For both series of nodules,the damage morphologies reproduced our simulated electric-field intensity distributions very well.These results indicated that the electric-field distribution was actually a bridge that connected the nodular mechanical properties to the final thermomechanical damage.Understanding of the damage mechanism of nodules was deepened by obtaining data on the influence of electric-field distributions on the damage behavior of nodules. | Xinbin Cheng Jinlong Zhang Tao Ding Zeyong Wei Hongqiang Li Zhanshan Wang | 2013 | Light(Science & Applications)2013,2,1: | 20 |
| 2 | Effect of composite supports on the methanation activity of Co-Mo-based sulphur-resistant catalysts显示文摘The effects of composite supports of CeO2-Al2O3,MgO-Al2O3,TiO2-Al2O3 or ZrO2-Al2O3 on the methanation activity of supported Co-Mo-based sulphur-resistant catalysts were investigated.The catalysts were further characterized by nitrogen adsorption measurement,X-ray diffraction and X-ray photoelectron spectroscopy.The catalyst of 5%CoO-15%MoO3 supported on CeO2-Al2O3,MgO-Al2O3,TiO2-Al2O3 or ZrO2-Al2O3 composite oxides,respectively,showed different catalytic performances of syngas methanation in the presence of hydrogen sulphide as compared with that of the 5%CoO-15%MoO3/Al2O3 catalyst.The Co-Mo/CeO2-Al2O3 catalyst shows the highest methanation activity among the tested catalysts.The enhanced methanation activity may be attributed to the improvement of the dispersion of active metal species and the inhibition of the formation of S6+. | Haiyang Wang Zhenhua Li Erdong Wang Can Lin Yuguang Shang Guozhong Ding Xinbin Ma Shaodong Qin Qi Sun | 2012 | Journal of Natural Gas Chemistry2012,21,6: | 15 |
| 3 | High CO methanation activity on zirconia-supported molybdenum sulfide catalyst显示文摘In this study, different methods were used to prepare MoO3/ZrO2 catalysts for sulfur resistant methanation reaction. It was found that MoO3/ZrO2 catalyst prepared by one-step co-precipitation method achieved high methanation performance. CO conversion could reach up to90% on 25 wt% MoO3/ZrO2 catalyst, much higher than that on the conventional 25 wt% MoO3/Al2O3 catalyst. The Mo-based catalysts were characterized by XRF, XRD, Raman, BET, TEM and H2-TPR etc. It was found that MoO3 particles were highly dispersed on ZrO2 support for 25 wt% MoO3/ZrO2 catalyst prepared at 65-85℃ because of its relatively larger pore size, which contributed to a high CO conversion.Meanwhile, when MoO3 loading exceeded the monolayer coverage, the formed crystalline MoO3 and ZrMo2O8might block the micropores of the catalyst and make the methanation activity declined. These results are useful for preparing highly efficient catalyst for CO methanation process. | Zhenhua Li Ye Tian Jia He Baowei Wang Xinbin Ma | 2014 | Journal of Energy Chemistry2014,23,5: | 15 |
| 4 | Mercury speciation and spatial distribution in surface waters of the Yarlung Zangbo River,Tibet显示文摘The Yarlung Zangbo River is the highest river in the world.It flows from west to east through the southern part of Tibet.The mercury(Hg)speciation and distribution in surface waters and soils near the bank of the Yarlung Zangbo River and its two tributaries,the Lhasa and Niyang Rivers,were investigated in June 2007.Simultaneously,major water quality parameters were also measured at the same stations.Total Hg(THg)and total methylmercury(TMeHg)concentrations in surface waters of the Yarlung Zangbo River ranged from 1.46 to 4.99 ng/L and from 0.06 to 0.29 ng/L,respectively,representing the background levels in river systems of the Tibetan Plateau.Particulate Hg(PHg)accounted for 69%of the THg,and the two Hg species had a significant relationship(r=0.990,P<0.01).Approximately 61%of the spatial distribution of THg was controlled by the concentrations of total suspended particles(TSP).Reactive Hg(RHg)concentrations ranged from 0.10 to 0.36 ng/L,and this fraction may play a weak role in terms of the transport and fate of Hg in surface waters.Dissolved methylmercury(DMeHg)constituted 71%of the TMeHg and was significantly correlated with TMeHg(r=0.746,P<0.01).The spatial distribution of TMeHg is not strongly affected by environmental factors such as THg,RHg,temperature,pH,dissolved organic carbon(DOC),and TSP.In addition,the inflow of both the Lhasa and Niyang Rivers probably influences the concentrations of THg in surface waters of the mainstream, but such an effect is not obvious for TMeHg. | ZHENG Wei KANG ShiChang FENG XinBin ZHANG QiangGong LI ChaoLiu | 2010 | Chinese Science Bulletin2010,55,24: | 11 |
| 5 | An Approach of Distributed Joint Optimization for Cluster-based Wireless Sensor Networks显示文摘Wireless sensor networks(WSNs) are energyconstrained,so energy saving is one of the most important issues in typical applications.The clustered WSN topology is considered in this paper.To achieve the balance of energy consumption and utility of network resources,we explicitly model and factor the effect of power and rate.A novel joint optimization model is proposed with the protection for cluster head.By the mean of a choice of two appropriate sub-utility functions,the distributed iterative algorithm is obtained.The convergence of the proposed iterative algorithm is proved analytically.We consider general dual decomposition method to realize variable separation and distributed computation,which is practical in large-scale sensor networks.Numerical results show that the proposed joint optimal algorithm converges to the optimal power allocation and rate transmission,and validate the performance in terms of prolonging of network lifetime and improvement of throughput. | Zhixin Liu Yazhou Yuan Xinping Guan Xinbin Li | 2015 | IEEE/CAA Journal of Automatica Sinica2015,2,3: | 10 |
| 6 | Refreezing of cast-in-place piles under various engineering conditions显示文摘In the construction of the Qinghai-Tibet Power Transmission Line(QTPTL), cast-in-place piles(CIPPs) are widely applied in areas with unfavorable geological conditions. The thermal regime around piles in permafrost regions greatly affects the stability of the towers as well as the operation of the QTPTL. The casting of piles will markedly affect the thermal regime of the surrounding permafrost because of the casting temperature and the hydration heat of cement. Based on the typical geological and engineering conditions along the QTPTL, thermal disturbance of a CIPP to surrounding permafrost under different casting seasons, pile depths, and casting temperatures were simulated. The results show that the casting season(summer versus winter) can influence the refreezing process of CIPPs, within the first 6 m of pile depth. Sixty days after being cast, CIPPs greater than 6 m in depth can be frozen regardless of which season they were cast, and the foundation could be refrozen after a cold season. Comparing the refreezing characteristics of CIPPs cast in different seasons also showed that, without considering the ground surface conditions, warm seasons are more suitable for casting piles. With the increase of pile depth, the thermal effect of a CIPP on the surrounding soil mainly expands vertically, while the lateral heat disturbance changes little. Deeper, longer CIPPs have better stability. The casting temperature clearly affects the thermal disturbance, and the radius of the melting circle increases with rising casting temperature. The optimal casting temperature is between 2 °C and 9 °C. | Lei Guo QiHao Yu XiaoNing Li XinBin Wang YongYu Yue | 2015 | Research in Cold and Arid Regions2015,7,4: | 8 |

| 8 | Effect of cobalt and its adding sequence on the catalytic performance of MoO_3/Al_2O_3 toward sulfur-resistant methanation显示文摘The effect of promoter cobalt and the sequences of adding cobalt and molybdenum precursors on the performance of sulfur-resistant methanation were investigated. All these samples were prepared by impregnation method and characterized by N2-adsorption, X-ray diffraction(XRD), temperature-programmed reduction(TPR) and laser Raman spectroscopy(LRS). The conversions of CO for Mo-Co/Al, Co-Mo/Al and CoMo/Al catalysts were 59.7%, 54.3% and 53.9%, respectively. Among these catalysts, the Mo-Co/Al catalyst prepared stepwisely by impregnating Mo precursor firstly showed the best catalytic performance. Meanwhile, the conversions of CO were 48.9% for Mo/Al catalyst and 10.5% for Co/Al catalyst. The addition of cobalt species could improve the catalytic activity of Mo/Al catalyst. The N2-adsorption results showed that Co-Mo/Al catalyst had the smallest specific surface area among these catalysts. CoMoO4species in CoMo/Al catalyst were detected with XRD, TPR and LRS. Moreover, crystal MoS2which was reported to be less active than amorphous MoS2was found in both Co-Mo/Al and CoMo/Al catalysts. Mo-Co/Al catalyst showed the best catalytic performance as it had an appropriate surface structure, i.e., no crystal MoS2and very little CoMoO4species. | Baowei Wang Yuqin Yao Minhong Jiang Zhenhua Li Xinbin Ma Shaodong Qin Qi Sun | 2014 | Journal of Energy Chemistry2014,23,1: | 5 |
| 9 | Metasurface-enabled on-chip multiplexed diffractive neural networks in the visible显示文摘Replacing electrons with photons is a compelling route toward high-speed,massively parallel,and low-power artificial intelligence computing.Recently,diffractive networks composed of phase surfaces were trained to perform machine learning tasks through linear optical transformations.However,the existing architectures often comprise bulky components and,most critically,they cannot mimic the human brain for multitasking.Here,we demonstrate a multi-skilled diffractive neural network based on a metasurface device,which can perform on-chip multi-channel sensing and multitasking in the visible.The polarization multiplexing scheme of the subwavelength nanostructures is applied to construct a multi-channel classifier framework for simultaneous recognition of digital and fashionable items.The areal density of the artificial neurons can reach up to 6.25×10^(6)mm^(-2) multiplied by the number of channels.The metasurface is integrated with the mature complementary metal-oxide semiconductor imaging sensor,providing a chip-scale architecture to process information directly at physical layers for energy-efficient and ultra-fast image processing in machine vision,autonomous driving,and precision medicine. | Xuhao Luo Yueqiang Hu Xiangnian Ou Xin Li Jiajie Lai Na Liu Xinbin Cheng Anlian Pan Huigao Duan | 2022 | Light(Science & Applications)2022,11,7: | 4 |
| 10 | Comparison of in vitro digestion methods for determining bioaccessibility of Hg in rice of China显示文摘Rice consumption can be a major pathway for mercury(Hg) exposure, which can cause health hazards to Chinese residents. To accurately assess the potential health risks, the bioaccessibility of Hg in rice samples collected at background and Hg-contamination sites was examined using four in vitro methods. The results showed that < 50% of the total mercury(THg) was bioaccessible in the studied rice samples. The THg bioaccessibility in the rice samples collected at the Hg-contaminated site was higher than that observed at the background area. The bioaccessibility of arsenic(As) and cadmium(Cd) was also evaluated for comparison of the four in vitro methods used in this study. The Physiologically Based Extraction Test was found to be the most accurate method based on the consistency of the results compared to those reported in previous studies. The estimated daily intakes of THg via rice consumption using the bioaccessibility data were found to meet the recommendation value set by the JECFA and the WHO in both sites. However, the potential health risk was not negligible at the Hg-contaminated sites, due to the high THg concentration and bioaccessibility in the rice samples. | Ze Wu Xinbin Feng Ping Li Che-Jen Lin Guangle Qiu Xun Wang Huifang Zhao Hui Dong | 2018 | Journal of Environmental Sciences2018,30,6: | 3 |
| 11 | Research and Development of Cadmium Sulphoselenide Red Pigment显示文摘Cadmium sulphoselenide was synthesized continuous substitution solid solution and the only known pigment to yield bright red color on ceramic decoration. Encapsulated cadmium sulphoselenide pigments could yield abundant hues from yellow to red with high opacity at high temperature. The color generation has a linear function relation with the substitution rate. The encapsulation formation process of zirconium silicate encapsulated cadmium sulphoselenide was shown. Insuffi cient encapsulation effi ciency and potential hazard to human and environment had limited the industrial application of cadmium sulphoselenide red pigment. Ink-jet printing decoration required fi ne size cadmium sulphoselenide red pigment on ceramic decoration. The review mainly focused on the synthesis techniques and industrial application of cadmium sulphoselenide red pigment. | 吴建锋 LI Kun XU Xiaohong ZHANG Yaxiang XU Xiaoyang LAO Xinbin | 2015 | Journal of Wuhan University of Technology(Materials Science)2015,30,6: | 3 |
| 12 | Farmland mercury contamination in the vicinity of an organic chemical factory in Guizhou,China显示文摘This study assesses the level of contamination of Hg in farmland soils along the irrigating channel down-stream from Guizhou Organic Chemical Factory (GOCF),where metallic mercury is used as a catalyst to produce acetic acid. The total input of mercury into the environment,as announced by GOCF,is 140 t in the past 30 years (1971-2000). Sampling sites were chosen based on the distance from the source of pollution—the chemical factory. A total of 39 samples were collected from the study area and analyzed for total mercury concentrations and methyl mercury concentrations. The characteristics of vertical and horizontal distributions of total mercury and methyl mer-cury in the study area (farmland) are described in this paper. Much attention was paid to the transformation of inor-ganic Hg into organic mercury species in soils as well. The results showed that the farmland has been heavily con-taminated by Hg. Land cultivation activity,land utilization style and distance from the pollution source could be the dominant factors controlling the distribution of THg and MeHg. It is observed that active transformation of inorganic Hg into organic mercury species (MeHg) usually takes place in paddy soils. | ZHANG Junfang QU Liya FENG Xinbin ZHANG Wei GUO Yanna LIN Kai LI Mei | 2008 | Chinese Journal Of Geochemistry2008,27,4: | 3 |
| 13 | Effect of MnO2 on Properties of SiC-mullite Composite Ceramics for Solar Sensible Thermal Storage显示文摘For improving the properties of Si C-mullite composite ceramics used for solar sensible thermal storage, Mn O_2 was introduced as sintering additive when preparing. The composite ceramics were synthesized by using Si C, andalusite, α-Al_2O_3 as the starting materials with non-contact graphite-buried sintering method. Phase composition and microstructure of the composites were investigated by XRD and SEM, and the effect of Mn O_2 on the properties of Si C composites was studied. Results indicated that samples SM1 with 0.2 wt% Mn O_2 addition achieved the optimum properties: bending strength of 70.96 MPa, heat capacity of 1.02 J·(g·K)-1, thermal conductivity of 9.05 W·(m·K)-1. Proper addition of Mn O_2 was found to weaken the volume effect of the composites and improve the thermal shock resistance with an increased rate of 27.84% for bending strength after 30 cycles of thermal shock(air cooling from 1 100 ℃ to RT). | 徐晓虹 lao xinbin wu jianfeng zhang yaxiang xu xiaoyang li kun | 2016 | Journal of Wuhan University of Technology(Materials Science)2016,31,3: | 3 |
| 14 | New ZnCe catalyst encapsulated in SBA-15 in the production of 1,3-butadiene from ethanol显示文摘ZnO-CeO2/SBA-15 catalysts were prepared by two kinds of solid-state grinding method and used for the production of 1,3-butadiene(1,3-BD) from ethanol.A mixture of SBA-15(with or without organic template) and metal precursors were ground in solid-state.The obtained catalysts were characterized by TG,N2 adsorption-desorption,TEM,XRD,Py-FTIR and NH_3-TPD techniques.Superior dispersion of metal oxides and more exposed acid sites were achieved on the catalyst lOZn_1Ce_5-AS with the presence of organic template in SBA-15 during the solid-state grinding process.The catalytic performance was evaluated in a fixed-bed reactor and a 1,3-butadiene selectivity of as high as 45% is achieved.This is attributed to the coupling effect of Zn and Ce species in the mesopores of SBA-15,in which Zn promotes ethanol dehydrogenation and Ce enhances aldol-condensation,respectively.Additionally,solvent-free method inspires new catalyst synthesis strategy for the production of 1,3-butadiene from ethanol. | Yujun Zhao Sijia Li Zheng Wang Shengnian Wang Shengping Wang Xinbin Ma | 2020 | Chinese Chemical Letters2020,31,2: | 3 |

The sample have the best properties in the series 'Ca-Al-Si', and water absorption (Wa) , porosity (Pa), bulk density (D), bending strength and compressive strength are 7.24%, 15.82%, 2.19 g.cm-3, 45.57 MPa and 56.81 MPa respectively, when the addition amount of East-lake sediment is 80% and the firing temperature is 1 100 ℃. In the series 'K-Al-Si', the sample with the best properties was obtained when addition amount of East-lake sediment was 70% and firing temperature was 1 060 ℃. The water absorption, porosity, bulk density, bending strength and compressive strength are 7.62%, 16.37%, 2.15 g~cm-3, 39.26 MPa, and 50.81 MPa respectively. They all come up to the national standardization, and meet the needs of manufacturing production. | 吴建锋 LENG Guanghui XU Xiaohong ZHANG Yaxiang LAO Xinbin Li Kun | 2012 | Journal of Wuhan University of Technology(Materials Science)2012,27,1: | 2 |
| 17 | Effects of typical algae species(Aphanizomenon flosaquae and Microcystis aeruginosa) on photoreduction of Hg2+ in water body显示文摘Photoreduction characteristics of divalent inorganic mercury (Hg2+) in the presence of specific algae species are still not well known.Laboratory experiments were conducted in the present study to identify the effects of different concentrations of living/dead algae species,including Aphanizomenon flosaquae (AF) and Microcystis aeruginosa (MA),on the photoreduction rate of Hg2+ under various light conditions.The experimental results showed that percentage reduction of Hg2+ was significantly influenced by radiation wavelengths,and dramatically decreased with the presence of algae.The highest percentage reduction of Hg2+ was induced by UV-A,followed by UV-B,visible light and dark for both living and dead AF,and the order was dark > UV-A > UV-B > visible light for both living and dead MA.There were two aspects,i.e.,energy and attenuation rate of light radiation and excrementitious generated from algae metabolisms,were involved in the processes of Hg2+ photoreduction with the presence of algae under different light conditions.The percentage reduction of Hg2+ decreased from 15% to 11% when living and dead AF concentrations increased by 10 times (from 106 to 105 cells/mL),and decreased from11% to ~9% in the case of living and dead MA increased.Algae can adsorb Hg2+ and decrease the concentration of free Hg2+,thus inhibiting Hg2+ photoreduction,especially under the conditions with high concentrations of algae.No significant differences were found in percentage reduction of Hg2+ between living and dead treatments of algae species.The results are of great importance for understanding the role of algae in Hg2+ photoreduction. | Rongguo Sun Yafei Mo Xinbin Feng Leiming Zhang Lin Jin Qiuhua Li | 2019 | Journal of Environmental Sciences2019,31,11: | 2 |

| 19 | EFFECT OF ELECTRIC CURRENT PULSE ON SUPERPLASTICITY OF ALUMINIUM ALLOY 7475显示文摘The superplastic deformation of aluminium alloy 7475 applied electric current pulse has been studied.The results presented that applying a high density current pulse raises both the elongation rate and the m value,and makes supperior superplastic properties at high strain rate of 10^(-2)s^(-1),the optimum deformation temperature could move from 530℃to 480~510℃,TEM observation showed the superplastic deformation of the alloy is the results of grain boundary slips and dislocation slips in grains under function of the electron wind;the intergranular tear is a main behavior of fracture of the alloy. | Li Yao Chen Hong Gu Yunqou Hu Xinbin | 1996 | Transactions of Nonferrous Metals Society of China1996,6,1: | 2 |
| 20 | Effect of boron addition on the MoO_3/CeO_2–Al_2O_3 catalyst in the sulfur-resistant methanation显示文摘The effect of boron on the performance of MoO_3/CeO_2–Al_2O_3 catalysts, which were prepared with impregnation method, was investigated. The catalysts were characterized with N_2 adsorption–desorption, XRD, H_2-TPR, and NH_3-TPD, and were tested in sulfur-resistant methanation. The results indicated that the MoO_3/CeO_2–Al_2O_3 catalysts modified by boron showed higher catalytic performance in sulfur-resistant methanation. The CO conversion increased from 47% to 62% with 0.5 wt% boron content. When the content of boron was under 0.5 wt%, the results suggested there was an increase in the amorphous form of MoO_3 caused by the generation of weak and intermediate acid sites, which had weakened the interaction between the active components and supports. While, the catalyst added 2.0 wt% boron showed the strong acid sites and the largest crystalline size resulting in the uneven distribution of ceria. | Baowei Wang Wenxia Yu Weihan Wang Zhenhua Li Yan Xu Xinbin Ma | 2018 | Chinese Journal of Chemical Engineering2018,26,3: | 2 |
