| 1 | Novel adaptive neural control of flexible air-breathing hypersonic vehicles based on sliding mode differentiator显示文摘A novel adaptive neural control strategy is exploited for the longitudinal dynamics of a generic flexible air-breathing hypersonic vehicle(FAHV).By utilizing functional decomposition method, the dynamics of FAHV is decomposed into the velocity subsystem and the altitude subsystem.For each subsystem, only one neural network is employed for the unknown function approximation.To further reduce the computational burden, minimal-learning parameter(MLP)technology is used to estimate the norm of ideal weight vectors rather than their elements.By introducing sliding mode differentiator(SMD) to estimate the newly defined variables, there is no need for the strict-feedback form and virtual controller.Hence the developed control law is considerably simpler than the ones derived from back-stepping scheme.Finally, simulation studies are made to illustrate the effectiveness of the proposed control approach in spite of the flexible effects, system uncertainties and varying disturbances. | Bu Xiangwei Wu Xiaoyan Ma Zhen Zhang Rui | 2015 | Chinese Journal of Aeronautics2015,28,4: | 11 |
| 2 | Hierarchical assembly of highly efficient visible-light-driven Ag/g-C_(3)N_(4)/kaolinite composite photocatalyst for the degradation of ibuprofen显示文摘A novel Ag/g-C_(3)N_(4)/kaolinite composite photocatalyst was fabricated for the first time through a two-step assembly strategy by employing in situ calcination and a photodeposition process.The synthesized Ag/g-C_(3)N_(4)/kaolinite composite reached a higher degradation rate of ibuprofen(IBP)with a reaction rate constant of 0.0113 min^(-1) at an Ag content of 7% under visible-light irradiation,which was approximately 1.87 times that of the Ag/g-C_(3)N_(4) composite.Based on the physicochemical properties,the enhanced photocatalytic activity was attributed to the stronger adsorption property,wider photoresponse range and more efficient separation and transfer of electron-hole pairs.Furthermore,the incorporation of monodispersed Ag nanoparticles onto the g-C_(3)N_(4)/kaolinite sheets provided more reactive sites for the IBP degradation.In addition,according to the EPR study and trapping experiments,it was demonstrated that holes(h^(+))should be the key reactive species.A possible pathway of IBP degradation was also proposed based on the detected intermediates.Overall,the results of this work may facilitate the design of a novel visible-light-driven photocatalyst with a high efficiency that is derived from a natural mineral for environmental remediation. | Zhiming Sun Xiangwei Zhang Xiongbo Dong Xiaorui Liu Ye Tan Fang Yuan Shuilin Zheng Chunquan Li | 2020 | Journal of Materiomics2020,6,3: | 8 |

| 4 | Interaction between angiogenin and fibulin 1: evidence and implication显示文摘Angiogenin 是涉及 tumorigenesis 的一个 angiogenic 因素。然而, angiogenins 行动的机制留下逃犯。在现在的学习,我们识别了 fibulin 1,细胞外的矩阵和血浆 glycoprotein,由酵母的一个交往 angiogenin 分子二混血儿的屏蔽。这个相互作用被二条不同途径进一步证实。首先, fibulin 1 是有由在 vitro 的 anti-angiogenin monoclonal 抗体的 angiogenin 的 co-immunoprecipitated,建议 angiogenin 与 fibulin 绑 1 直接。然后,荧光回声精力转移分析显示出那 fibulin 1 在 COS-7 房间与 angiogenin 交往了,证明绑定能发生在细胞的上下文。作为 fibulin, 1 在房间增长起一个重要作用,移植,粘附,并且稳定新形成的血容器墙,在 fibulin 之间的相互作用 1 并且 angiogenin 可能在 angiogenesis 或 tumorigenesis 加重 angiogenin 的一可能的机制。 | Hui Zhang Xiangwei Gao Chunhua Weng Zhengping Xu | 2008 | Acta Biochimica et Biophysica Sinica2008,40,5: | 4 |
| 5 | Degradation of Formaldehyde and Benzene by TiO2 Photocatalytic Cement Based Materials显示文摘A novel photocatalytic cement based material was prepared. The distribution of TiO_2 on the surface of cement was characterized by scanning electron microscope(SEM) and X-ray diffraction(XRD), which showed the relationship of photocatalysis and presence of TiO_2. TiO_2 also had an impact on cement hydration, which was studied by thermal analysis. With 300 W UV illuminations, formaldehyde and benzene were degraded efficiently by the prepared photocatalytic cement based materials. 15wt% TiO_2/cement showed the highest degradation efficiency and capability. The results show that formaldehyde and benzene can be degraded within 4 and 9 hours, respectively. Besides, inorganic ions can induce TiO_2 agglomeration. As a result, the presence of inorganic ions in cement is unfavorable for degradation. The photocatalytic cement based materials were fabricated and the degradation efficiency of formaldehyde was measured on building roof under sunlight illumination. Formaldehyde in glass chamber can be degraded thoroughly within 10 days. | 刘鹏 YU Xiangwei 王发洲 ZHANG Wenqin YANG Lu LIU Yunpeng | 2017 | Journal of Wuhan University of Technology(Materials Science)2017,32,2: | 3 |
| 6 | M0S2 dual-gate transistors with electrostatically doped contacts显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDs)such as molybdenum disulfide(M0S2)have been intensively investigated because of their exclusive physical properties for advaneed electronics and optoelectronics.In the present work,we study the M0S2 transistor based on a novel tri-gate device architecture,with dual-gate(Dual-G)in the channel and the buried side-gate(Side-G)for the source/drain regi ons.All gates can be in depe ndently con trolled without in terfere nee.For a MoS2 sheet with a thick ness of 3.6 nm,the Schottky barrier(SB)and non-overlapped channel region can be effectively tuned by electrostatically doping the source/drain regions with Side-G.Thus,the extri nsic resista nee can be effectively lowered,and a boost of the ON-state cur re nt can be achieved.Mean while,the cha nn el c ontrol remai ns efficient under the Dual-G mode,with an ON-OFF current ratio of 3 x 107 and subthreshold swing of 83 mV/decade.The corresponding band diagram is also discussed to illustrate the device operati on mechanism.This no vel device structure ope ns up a new way toward fabricati on of high-performance devices based on 2D-TMDs. | Fuyou Liao Yaocheng Sheng Zhongxun Guo Hongwei Tang Yin Wang Lingyi Zong Xinyu Chen Antoine Riaud Jiahe Zhu Yufeng Xie Lin Chen Hao Zhu Qingqing Sun Peng Zhou Xiangwei Jiang Jing Wan Wenzhong Bao David Wei Zhang | 2019 | Nano Research2019,12,10: | 2 |
| 7 | Enhanced visible-light-assisted peroxymonosulfate activation over MnFe_(2)O_(4) modified g-C_(3)N_(4)/diatomite composite for bisphenol A degradation显示文摘The MnFe_(2) O_(4)/g-C_(3) N_(4)/diatomite composites(Mn/G/D) were prepared via a facile precipitation-calcination method in this study.The Mn/G/D possessed higher specific surface area,lower electron-hole pairs' recombination rate,as well as wider and stronger visible light absorption capacity.Since the synergistic effect between g-C_(3 )N_(4) and MnFe_(2) O_(4),the photogene rated electron could transfer from g-C3 N4 to MnFe_(2) O_(4),which could promote the migration of electrons as well as enhance the photocatalytic activity and peroxymonosulfate(PMS) activation efficiency.Mn/G/D-5% composite displayed the excellent degradation performance of bisphenol A(BPA) with the removal efficiency of 99.9% under PMS/Vis system,which was approximately 2.47 and 63.8 times as high as that of the Mn/G/D-5%/PMS and Mn/G/D-5%/Vis system,respectively.Moreover,negative electricity derived from diatomite surface also promoted the photogenerated carriers' migration,and the degradation rate constant was around 2.4 times higher than that of MnFe_(2) O_(4)/g-C_(3) N_(4)(Mn/G).In addition,quenching experiments showed that both radical pathway(h^(+),·OH,·O_(2)^(-)and SO_(4)·^(-)) and non-radical pathway(^(1) O_(2)) were responsible for the degradation of BPA. | Xiangwei Zhang Chunquan Li Ting Chen Ye Tan Xiaorui Liu Fang Yuan Shuilin Zheng Zhiming Sun | 2021 | International Journal of Mining Science and Technology2021,31,6: | 2 |

| 11 | Highly efficient transparent quantum-dot light-emitting diodes based on inorganic double electron-transport layers显示文摘Herein,we report the fabrication of high-performance transparent quantum-dot light-emitting diodes(Tr-QLEDs)with ZnO/ZnMgO inorganic double electron-transport layers(ETLs).The ETLs effectively suppress the excess electron injection and facilitate charge balance in the Tr-QLEDs.The thick ETLs as buffer layers can also withstand the plasma-induced damage during the indium tin oxide sputtering.These factors collectively contribute to the development of Tr-QLEDs with improved performance.As a result,our Tr-QLEDs with double ETLs exhibited a high transmittance of 82%at 550 nm and a record external quantum efficiency of 11.8%,which is 1.27 times higher than that of the devices with pure ZnO ETL.These results indicate that the developed ZnO/ZnMgO inorganic double ETLs could offer promising solutions for realizing high-efficiency Tr-QLEDs for next-generation display devices. | Nan Zhang Xiangwei Qu Quan Lyu Kai Wang Xiao Wei Sun | 2021 | Photonics Research2021,9,10: | 2 |
| 12 | Microstructural Instability of an Experimental Nickel-Based Single-Crystal Superalloy显示文摘Microstructural instability with the precipitation of topologically close-packed(TCP)phases of an experimental nickel-based single-crystal superalloy has been investigated.A significant amount of σ phases are distinguished in the interdendritic region of the as-cast samples after thermal exposure at 900℃ for 1000 h.Theσphases are preferentially precipitated at the periphery of coarse γ/γ′eutectic,and their morphological evolution from needles to granules is observed.Microstructural analysis suggests that the local segregation of Cr and Ti at the periphery of coarse γ/γ′eutectic accounts for the formation ofσphases in the as-cast samples.After heat treatment with low solution temperature and short holding time,the dendritic segregation of alloying elements(i.e.,W,Re,Ti and Ta)and the volume fraction of γ′phase in the interdendritic region are similar to that of the as-cast samples.However,no TCP phases are present in the interdendritic region of the heat-treated samples after thermal exposure,which is primarily ascribed to the elimination of local segregation of Cr and Ti near the coarse γ/γ′eutectic.Moreover,small quantities ofμphases are precipitated in the secondary dendrite arm near the interdendritic region after thermal exposure,due to the increased volume fraction ofγ′phase and the concomitant enrichment of W and Re in theγmatrix. | Bin Yin Guang Xie Xiangwei Jiang Shaohua Zhang Wei Zheng Langhong Lou | 2020 | Acta Metallurgica Sinica(English Letters)2020,33,10: | 1 |
