A protective coating has been applied onto the phosphated panels using cathodic electrocoating in two different dry film thickness namely 8µm and 20µm. The corrosion resistance of cathodic electrocoatings has been studied using AC/DC/AC method. Twelve cycles of AC/DC/AC test were carried out on each sample which the DC voltage of the first 6 cycles were -4 V VS. Ag/AgCl @ 20 minutes followed by...

Hybrid inorganic-organic material based on Keggin type polyoxometalaes ([SiW12O40]4-) and praseodymium-dipicolinic acid (pydc; 2,6-pyridindicarboxylic acid) with the formula of [Pr2(pydc)2(H2O)8][H2SiW12O40]•4H2O (1) is obtained under a hydrothermal condition. Compound 1 was characterized by infrared spectrum and elemental analysis and its structure was further determined by single-crystal X-ra...
