Manganese and Iron Catalysts in Alkyd Paints and Coatings

Paints and Coatings

Paints and Coatings: Pyrolysis: Gas Chromatography

In this review, the principles behind, and the utility of, fractionation of subcellular organelles by centrifugal techniques have been explored. Common methods used, and a review of the advantages and disadvantages of certain experimental tools (centrifuges, rotors, and aqueous media used for fractionation) were also reviewed and tables and graphs useful for designing protocols were also provided.

Manganese and Iron Binding to Human Transferrin

The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

Time to Ban Lead in Industrial Paints and Coatings

In the U.S. and most high-income countries, regulations already restrict the use of lead paint for residential applications. However, few countries have enacted comprehensive bans on the use of lead additives in all paints. In 2009, more than 120 countries at the UN International Conference on Chemicals Management (ICCM) voted to phase-out all lead paints (1). Since then, a few countries includ...
