Abstract The durability of an innovative polymeric coating recently developed by the authors to prevent stress corrosion in annealed glass is herein examined. coating, having functional graded properties through thickness, optimised provide a very good adhesion with and excellent hydrophobic behavior on side exposed environment, thus creating barrier humidity, which triggering agent for corrosi...

In this paper a novel anti-reflection (AR) coating based on silicon nano-bars is designed and its impact on the performance of crystalline silicon (c-Si) thin-film solar cells is extensively studied. Silicon nano-bars with optimized size and period are embedded on top of the active layer, under a 100nm Si3N4 layer. As a result of the proposed layer stack, an inhomogeneous intermediate layer wit...

Abstract This work is devoted to the problem of thermal fracture a functionally graded coating on homogeneous substrate (FGC/H) with an emphasis analysis special system cracks that simulates curved interface. The FGC/H structure contains pre-existing crack in FGC, both edge (which are often seen structures) and internal cracks. stress intensity factors calculated. (Generally, Mode I II nonzero....

A mathematical model describing the deformation of a material caused by reverse piezoelectric effect is proposed. The based on an axisymmetric problem electroelasticity for half-space with functionally-graded coating. An electric potential difference applied across circle area surface (an electrode whose thickness and elastic properties are neglected) infinity boundary half-space. Arbitrary ind...

Functionally graded coatings (FGCs) have a material composition continuously varying through the thickness but uniform in surface parallel to coated substrate. When used as thermal barrier on metallic substrate, coating varies from an almost pure metal near substrate ceramic adjacent outer exposed hot environment. Challenging issues producing high quality FGCs presence of external disturbances ...

Let $G$ be a monoid with identity $e$. In this paper, first we introduce the notions of $G$-graded hyperrings, graded hyperideals and graded hyperfields in the sense of Krasner hyperring $R$. Also, we define the notion of a greded $R$-hypermodules and some examples are presented. Then we investigate graded maximal, graded prime and graded primary hyperideals of a graded hyperring $R$. Finally, ...
