--The inhibition of the corrosion of mild steel in hydrochloric acid solutions by the extract of Artemisia Herba-Alba has been studied using gravimetric and electrochemical measurement. Inhibition was found to increase with increasing concentration of the inhibitor. Values of inhibition efficiency calculated from weight loss and potentiodynamic polarization are in good agreement. This value goe...

An epimer of the known glycosidase inhibitor noeurostegine, galacto-noeurostegine, was synthesised in 21 steps from levoglucosan and found to be a potent, competitive and highly selective galactosidase inhibitor of Aspergillus oryzae β-galactosidase. Galacto-noeurostegine was not found to be an inhibitor of green coffee bean α-galactosidase, yeast α-glucosidase and E. coli β-galactosidase, wher...

In this work, the extract of the leaves and berries of solanum nigrum was examined as a green corrosion inhibitor for zinc in 0.5N HCl by using weight loss, gasometric and thermometric methods. Results obtained showed that the extract of solanum nigrum offered good protection against corrosion of zinc metal and exhibited high inhibition efficiencies. The inhibition efficiency was found to incre...

Extract of Shorea robusta bark as a novel green inhibitor for mild steel (MS) corrosion has been investigated. Qualitative chemical tests, UV, and FTIR measurements were carried out to confirm phytochemicals in the extract. Gravimetric well electrochemical methods employed examine inhibition efficiency Effects concentration, immersion time working temperature investigated by weight loss measure...
