the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...

High-reflective coatings are indispensable in order to manufacture mirrors with highest possible reflectivity. The maximum reflectivity can be achieved by all-dielectric coatings; however, the spectral bandwidth of these mirrors is limited. For astronomical applications metal based coatings (Al, Au, Ag) are commonly applied, as they allow high reflectivity and at the same time a broad spectral ...

Numerical simulations have shown that low reflectivity’s at the surface of planar cell coated with a single layer can be obtained. For example, for coatings Si3N4 and HfO2 materials, reflectivity values around 3% 2% respectively are Structures multilayer such as MgF2 /SiNx: H/Si, give very 1%. Thus, refractive index coating is an important parameter plays major role in optical properties materi...

Computational reflection is gaining interest in practical applications: modern software frequently requires strong adaptability conditions to be met in order to fit a heterogenous and evolving computing environment. Most of these applications only need limited but flexible reflective capabilities rather than sophisticated reflective languages and reflective runtime systems. However, there is no...
