Porous Anodic Aluminum Oxide (AAO) films were prepared by two-step anodizing in sulfuric and oxalic acid solutions and observed by transmission electron microscope (TEM) and X-ray diffraction. The results show that the form of AAO film is affected by the varieties and concentrations of...

The adsorption and the growth of ZnO on α-Al2O3(0001) surface at various temperatures are theoretically calculated by using a plane wave pseudopotentials (USP) method based on density functional theory. The average adsorption energy of ZnO at 400, 600, and 800°C is 4.16±0.08, 4.25±0.11, and...

In this paper, by using β-SiC powder as a matrix and mixing different content of C, a series of SiC–C composites with solid phase sintering under different temperature were prepared. The relative density, electrical properties and microwave absorption properties at X band were measured...

The fabrication process of Si-steel thin-strip by twin-roll continuous casting was described and the quality of the obtained Si-steel thin-strip was measured. Si-steel strips with 0.5–6.5 wt.% Si content were successfully prepared, and proper parameters including pouring temperature, height of...
