| 1 | Mechanism of vertical crack formation in Yb_(2)SiO_(5) coatings deposited via plasma spray-physical vapor deposition显示文摘Plasma spray-physical vapor deposition(i.e.,PS-PVD)is a promising method for obtaining advanced environmental barrier coatings(EBCs).The EBCs must meet some requirements in the application,in which the thermal cycle performance affects the service lifetime.The preparation of artificial vertical cracks in Yb_(2)SiO_(5) coatings is an effective approach for meeting the requirements above because vertical cracks provide a strain tolerance.To clarify the formation mechanism of vertical cracks during the PSPVD,the effects of coating thickness and substrate temperature on the formation of vertical cracks were investigated.In addition,the interactions of spray powder and plasma flame during coating deposition were also characterized by optical spectroscopy.It is indicated that vertical cracks are formed due to a thermal expansion mismatch between Yb_(2)SiO_(5) and mullite coating,transient cooling after deposition and the nucleation of evaporated Yb_(2)SiO_(5) as well. | Xiaofeng Zhang Chao Wang Ruijun Ye Chunming Deng Xinghua Liang Ziqian Deng Shaopeng Niu Jinbing Song Guo Liu Min Liu Kesong Zhou Jian Lu Junli Feng | 2020 | Journal of Materiomics2020，6，1： | 6 |
| 2 | Effect of Anodization Parameters on Morphology and Photocatalysis Properties of TiO_2 Nanotube Arrays显示文摘Highly ordered TiO2 nanotube arrays were fabricated via electrochemical anodization of high purity Ti foil in fluoride-containing electrolyte. The effects of applied anodization potential, anodization time on the formation of TiO2 nanotube arrays and the photocatalytic degradation of methylene blue(MB) were discussed. The TiO2 nanotube arrays calcined at 500 °C for 2 h show pure anatase phase. The pore diameters of TiO 2 nanotube arrays can be adjusted from 30 to 90 nm using a different anodization voltage.Anodization time mainly influenced TiO 2 tube length, and by increasing the anodization time, the nanotube length became longer gradually. When the anodization potential was 40 V, the average growth rate of TiO 2 nanotube was about 4.17 μm/h. Both anodization potential and time had important effects on the photocatalytic efficiency. The TiO 2 nanotube arrays obtained at anodization potential of 40 V for 1 h showed the best photocatalytic degradation ratio of MB. | Lianjie Qin Qijing Chen Ruijun Lan Runqian Jiang Xiao Quan Bin Xu Feng Zhang Yongmin Jia | 2015 | Journal of Materials Science & Technology2015，31，10： | 3 |
| 3 | Energy Aware Spectrum Access in Cognitive Radio Networks with Imperfect Channel Sensing显示文摘Due to the problem of spectrum underutilization and energy inefficiency in wireless communications,the research on energy efficient Cognitive Radio Networks (CRNs) has received significant attention in both industry and academia.In this paper,we consider the problem of optimal spectrum selection and transmission parameters design with the objective of minimizing energy consumption in CRNs.Since the system state cannot be directly observed due to miss detections and estimation errors,we formulate the optimal spectrum access problem as a Partially Observable Markov Decision Process (POMDP).In particular,the proposed scheme selects the optimal spectrum,modulation and coding scheme,transmission power,and link layer frame size in each time slot according to the belief state,which captures all the history information of past actions and observations.The optimal policy can be acquired by solving POMDP problem with linear programming based algorithm.Simulation results show that significant energy savings can be achieved by the proposed scheme. | Wei Yifei Du Chenhui Feng Ruijun F.
