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...

China’s growth has been spectacularly high and persistent over the last few decades. However, there have been regular expressions of concern about the uneven distribution of the benefits across regions and, at times, it has been asserted that the regional distribution of available investment...

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...

Supply chains are assessed for the contribution they make in improving business processes. Assessment also looks at the return on investment and improves the overall functioning of the entire chain. However, supply chains extend beyond geographical borders and span a wide variety of activities;...

Supplier selection is the process by which suppliers are reviewed, evaluated, and chosen to become part of a company’s supply chain. To select the best suppliers in the presence of cardinal data, ordinal data, nondiscretionary factors, and weight restrictions, this paper proposes a new...
