Chemical Removal of Lead Corrosion Products

Experimental investigation of steel corrosion in Lead Bismuth Eutectic (LBE): characterization, species identification, and chemical reactions

The goal of the present research is to achieve a basic understanding of corrosion of steels by Lead Bismuth Eutectic (LBE). Liquid LBE is under consideration in the transmuter as both a coolant and a target material. There have been studies of LBE, especially by the Russians, but a fundamental understanding and verification of its role in the corrosion of steels is still very

Natural products as lead structures: chemical transformations to create lead-like libraries.

In this review, we analyze and illustrate the variation of the two main lead-like descriptors [molecular weight (MW) and the partition coefficient (logP)] in the generation of libraries in which a natural product (NP) is used as the guiding structure. Despite the different approaches used to create NP-like libraries, controlling these descriptors during the synthetic process is important to gen...

Corrosion of Metals in Wood Products

EXAFS studies of the chemical state of lead and copper in corrosion products formed on the brass surface in potable water.

EXAFS measurements in the corrosion deposits were performed on Bell Labs-UIUC beamline X16C at the NSLS at Brookhaven National Laboratory in grazing incidence fluorescence mode at room temperature. EXAFS in the reference Cu and Pb metal foils, malachite, cerussite and hydrocerussite were measured in transmission. Sagittally focused second crystal in the double crystal Si (111) monochromator all...

Anomalous dissolution of metals and chemical corrosion

An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be expected from the Faraday law with the use of the expected valence of the formed ions. Mechanical disintegration, gas bubble blocking, hydrogen e...
