Various tools were used in the investigation and analysis processes of iron window grille sabil Ramadan. Metallographic Microscope, SEM-EDS Carbon-Sulfur, XRD indicated that was manufactured from low carbon steel. X-ray diffraction corrosion products showed they mainly consist Magnetite Fe3O4, Goethite α-FeO(OH), Akaganeite β-FeO(OH). Such information regarding may assist conservation process t...

Implantation of synthetic materials into the body elicits inflammatory host responses that limit medical device integration and biological performance. This inflammatory cascade involves protein adsorption, leukocyte recruitment and activation, cytokine release, and fibrous encapsulation of the implant. We present a coating strategy based on thin films of poly(N-isopropylacrylamide) hydrogel mi...

During the process of thermal spray coating, molten powders are sprayed and deposited on substrates to generate protective coatings. It is essential to have a clear understanding of the physics of droplet impingement on the surface of substrates for better control of the generation of splats and the structure of coating. A numerical model is developed in this paper to simulate the dynamics of t...

Protective coatings have been deposited on electrogalvanized steel by immersion in solutions containing 2-Butyne-1.4-diol propoxylate (C7H11O3), cerium nitrate, sodium nitrate and sodium sulphate for different immersion periods. The surface morphology and chemical composition of the coatings formed on the electrogalvanized steel were studied using field emission gun scanning electron microscopy...

Abstract This research aimed to study and compare the mechanical durability contamination resistance of organic spectacle lenses for everyday use, based on CR-39 poly(allyl diglycol carbonate) (PADC), from different manufacturers. The objects this are selected corrective three Each examined brand is represented by a reference uncoated lens other with types protective coating. sample has been ch...
