Nowadays, nanoporous films are widely employed in biochemical applications or in optophotonic devices such as displays, solar cells, or light-guiding systems. In particular, the technological feasibility of nanoporous layers with low refractive indices has recently enabled the development of high-efficiency anti-reflection coatings. In this paper, we report on hybrid polymer nanoporous films th...

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...

The construction of optimized biological fuel cells requires a cathode which combines the longevity microbial catalyst with current density an enzymatic catalyst. Laccase-secreting fungi were grown directly on cell to facilitate exchange inactive enzymes active enzymes, goal extending lifetime laccase cathodes. Directly incorporating laccase-producing fungus at extends operational cathodes whil...

Let $G$ be a group with identity $e$. Let $R$ be a $G$-graded commutative ring with a non-zero identity and $M$ be a graded $R$-module. In this article, we introduce the concept of graded almost semiprime submodules. Also, we investigate some basic properties of graded almost semiprime and graded weakly semiprime submodules and give some characterizations of them.

in this paper, we consider locally graded groups in which every non-permutable subgroup is soluble of bounded derived length.
