In the present work,transparent and anti-fogging AlPO_(4)-5 films were prepared on glass substrates using a novel developed process.The process entails a simple in-situ sol–gel followed by vapor phase transport.The in-situ sol–gel process was implemented by coating the precursor sols for the synthesis of AlPO4-5 on the glass substrates successively using the spin-coating method.The films and powders scribed from the films were characterized by X-Ray diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),scanning electron microscope(SEM),atomic force microscope(AFM),X-ray photoelectron spectroscopy and transmission electron microscope(TEM).The unique films were composed of oblique oriented nanoflake AlPO_(4)-5 crystals with the thickness of about 20 nm.The formation of nano-flake crystals can be ascribed to the high concentration of the precursors,resulting in the formation of a supersaturation system.The obtained films showed high antifogging performance due to the superhydrophilicity with a water contact angle of lower than 1.0°.The silicone oil contact angle was also low about 8.2°.In addition,heteroatom-substituted AlPO_(4)-5 films showing different colors can be obtained easily by simply adding transition metal ions in the phosphate acid solution during the preparation that can extend the application of the method for different coating demand. 展开更多

Here, several examples of Java programs are presented. These examples show some major features that Java language provides, such as multi-thread, exception handling, network application writing, and the usage of Java applets. This article also shows some ways of setting up a Java language programming environment. All these examples are correct and ready to run. 展开更多

作者 吴公彝 《新东方英语(中学版)》 2016年第4期64-65,共2页
在塞内加尔有一个粉红色的湖,名叫玫瑰湖(又称Lac Rose),其海拔高度是死海的1.5倍。这里是嗜盐杆菌的主要栖息地——嗜盐杆菌是一种单细胞的喜盐微生物,呈红色或紫色。实际上,受一天的时间以及光照量的影响。
