Waware, Umesh Somaji; Arukula, Ravi; Hamouda, A. M.S.; Rashid, Mohd ( Springer Science and Business Media Deutschland GmbH , 2022 , Article)In the present work, we prepared enormously soluble poly (aniline-co-3-aminophenol) (PA-co-3-AP) copolymers via a simple chemical oxidative method with aniline and 3-aminophenol, and their properties are compared with ... -
Effect of addition of Pd on electrodeposited Ni–B coatings
Waware, Umesh Somaji; Nazir, Roshan; Hamouda, A. M.S.; Pradhan, Ajaya Kumar ( Springer Science and Business Media Deutschland GmbH , 2022 , Article)In this study, the effect of addition of a noble metal (Pd) to the Ni–B nano-coating is studied. The Ni–B and Ni–B–Pd coatings are synthesized from aqueous electrolytes using direct current. The Ni–B coating is found to ... -
