CORROSION INHIBITION EFFICIENCIES OF POLYMERIC MATERIALS ON ALLOY STEEL IN DILUTE HYDROCHLORIC ACID AND SODIUM HYDROXIDE SOLUTIONS AT AMBIENT TEMPERATURE

A corrosion control test was conducted on alloy steel, using polymeric coatings (polyurethane, bitumen (medium airing), and high-density polyethylene) in dilute HCl solutions of pH values 4, 7, and 12, respectively for acid, neutral and alkaline solutions at ambient temperature.In the study, Eighty-four coupons of alloy steel were used.The coupons

High-efficient ZnO-based Spindle Mixer Parts and Accessories nanorod array light-emitting diodes (LEDs) were grown by an oblique-angle deposition scheme.Due to the shadowing effect, the inclined ZnO vapor-flow was selectively deposited on the tip surfaces of pre-fabricated p-GaN nanorod arrays, resulting in the formation of nanosized heterojunction

Objective: Worse neighborhood socioeconomic environment (NSEE) may contribute to an increased risk of type 2 diabetes (T2D).We examined whether the relationship between NSEE and T2D differs by sex and age in three study populations.Research design and methods: We conducted a harmonized analysis using data from three independent longitudinal study s
