In view of the fact that corrosion costs large sums of money and touches countless facets of human activities, every possible effort needs to be made to find ways to stop it from starting. In this regard inhibition of corrosion has become a thriving commercial activity, worldwide. Much research has been devoted to discovering newer strategies to inhibit corrosion with concomitant improvements in corrosion inhibition materials. This review will focus on the advances in materials and technologies for corrosion inhibition, with particular attention to the evolution of technologies and materials prior to the advent of coatings, the exploitation of ‘green methods’ which use anti-corrosion materials, which protect materials without fouling the environment; and the present and projected role of nanotechnology in inhibition of corrosion. This review brings together the collected wisdom of several disciplines. The latter addressed and/or are continuing to address the need for cost-effective materials to protect strategic metals used in the domestic and industrial sectors of most countries. The scope for improving the quality of materials, required for shielding these metals from the ravages of degrading agents, present in the environments of most cities, is lucidly articulated.

Boron nitride nanomaterial based solid acid catalyst is an efficient and reusable sulfonic acid catalyst for the one-pot synthesis of 9-(2-(4-ethylpiperazin-1-yl)quinolin-3-yl)-3,3-dimethyl-3,4,9,10-tetrahydroacridin-1(2H)-one derivatives under microwave irradiation conditionsvia. The Knoevenagel and Michael type reactions. The catalyst was prepared by simply mixing boron nitride and 3-amino-4-methoxybenzenesulfonic acid in a safe method. The morphological properties of the catalyst was determined by using FT-IR, XRD, TEM, SEM and Raman spectroscopy. The synthesised catalyst was employed in a Knoevenagel and Michael type reaction to synthesise novel ethylpiperazinyl-quinolinyl based acridine derivatives. Furthermore, the newly-synthesised compounds was used for molecular docking in Hsp90 protein studies. The method developed in this study has the advantages of good yield, simplicity coupled with safety and short reaction time. Most importantly it was found that the solid acid catalyst can be recycled with minimal loss of activity over five cycles.
