Chemistry and kinetics of air reactions with plutonium monoxide monohydride (PuOH) and with mixtures of the oxide hydride and plutonium metal are defined by results of pressure-volumetemperature (PVT) measurements. Tests with specimens prepared by total and partial corrosion of plutonium in 0.05 M sodium chloride solution show that reaction of residual water continues to generate H, after liqui...

A leak is an undesirable interconnection between isolated parts of a system or between two systems and is suspected if there is any abnormal behavior of a system, such as loss of pressure, contamination of product or loss of process efficiency. A leak in a system can occur due to an unintended crack, corrosion or porosity, hole in an enveloping wall, loosening of bolts/joints and cracking of ga...

Acute local toxicity refers to the local toxic effects that may result from a single exposure to a chemical or product, by way of the oral, dermal, ocular or inhalation routes. The exposure can be incidental, accidental or deliberate (for example, in the case of cosmetics and certain medicines). The dermal route of exposure can also be a significant route for entry into the systemic circulation...

1.1.1 Historical Background of In Vitro Ocular Irritation/Corrosion Test Methods and Rationale for Their Development The location of the eye and its anatomy predisposes it to exposure to a variety of environmental conditions (e.g., ozone, pollen) and substances on a daily basis. Injury from ocular exposure to a variety of chemical agents can lead to a range of adverse effects with the most extr...

Abstract A finite element model is developed to study dynamics of atmospheric corrosion carbon steel, focusing on the influence thin electrolyte film thickness under varying product porosity. Calculations have been done evaluate impact and porosity oxygen diffusion path, hindrance effect products metal surface activity. The time evolution current density controlling steps in process are explore...

Corrosion is one of the major problems in the oil and gas industry is one that automatically allocates huge sums annually. Polyurethane is a thermoses polymer with various applications. Using form this polymer has spread for military applications by Otto Bayer in 1930. In one general look polyurethane is product of Iso Syanate and ploy with each other, So that: Iso + ploy = polyurethane. Spend ...

The paper analysis the material composition, properties and application technology of 0Cr18Ni10Ti , and it is an understanding of the material’s mechanical properties and corrosion-resistance. The using of stabilization heat treatment process, solution heat treatment, controlling the chemical composition and production process conditions, etc. improved the overall performance of 0Cr18Ni10Ti and...

Chlorinated rubber, the addition and substitution reaction product of natural rubber and chlorine gas, is knOWn for its low Water vapor permeability, good chemical resistance, abrasion resistance, corrosion resistance, and flame retardant properties.' Consequently, it is used as a coating component in a.variety of coating applications including marine coatings, swimming pool coatings, and corro...

Experiments on the diffusion-limited corrosion of porous copper clusters in thin gap cells containing cupric chloride are reported. By carefully comparing corrosion front velocities and concentration profiles obtained by phase-shift interferometry with theoretical predictions, it is demonstrated that this process is well-described by a one-dimensional mean-field model for the generic reaction A...

PURPOSE To evaluate the effectiveness of peracetic acid in the microbiological sterilisation of dental materials. METHODS Peracetic acid solution was evaluated at concentrations of 800, 1500 and 2500 ppm. At these concentrations, it was determined whether peracetic acid caused corrosion to dental instruments and induced cellular mutagenicity and cytotoxicity. In addition, the minimum inhibito...
