Plant-based synthesis of lead oxide nanoparticles using
Abstract This study implicates the synthesis of lead oxide nanoparticles (PbO-NPs) in a green manner by using the extracts of Trigonella feonumgraecum for stabilizing and capaging purposes. The techniques of UV-Vis, FTIR, TGA-DTA, FESEM, EDX, and XRD were considered to evaluate the synthesized nanoparticles. The assay of …

Lead Refining by Electrolysis
Lead- fluosilicate is one of the most soluble of salts; so there is never any danger of its crystallizing out at any degree of concentration possible under this method. The lead-solution is then filtered and run by gravity into the refining-tanks. The solution originally used at Trail contained about 6 per cent. Pb and 15 per cent. SiF6.

Nanoparticles in sustainable agriculture: An emerging opportunity
Zinc oxide nanoparticles. Soils as well as plants generally face the deficiency of zinc which is due to the lower availability of zinc and its limited amount in calcium carbonate enriched soils due to alkaline pH [44, 45]. To mitigate this, zinc sulphate fertilizer is used as alternatives, but, even then plants suffer from zinc deficiency.
