Synthesis and tribological investigation of 4-vinyl guaiacol–based thioether derivatives as multifunctional additives and their interactions with the tribo surface using quantum chemical calculations

Kontham, V.; Padmaja, K.V; Madhu, D. (Elsevier B.V., 2020)

Novel 4-vinyl guaiacol based thioether derivatives were synthesized in a three-step reaction procedure by thiol-ene coupling as the key step. The synthesized compounds were characterised by spectroscopic techniques and ...
Synthesis of ricinoleate anion based ionic liquids and their application as green lubricating oil additives

Kontham, V.; Padmaja, K.V; Madhu, D. (Elsevier B.V., 2020-10)

Ricinoleate anion based ionic liquids (ILs) were synthesized from four different nitrogen containing cationic counterparts such as tetrabutylammonium, tetrapropylammonium, cetyltrimethylammonium, imidazolium. Tribological ...
Synthesis of β-carboline fatty alcohol hybrid molecules and characterization of their biological and antioxidant activities

Kontham, V.; Ippakayala, B.; Madhu, D. (Elsevier B.V., 2021-06)

Nine new β-carboline fatty alcohol hybrids were synthesized from natural amino acid L-tryptophan by the conjugation of 10-undecen-1-ol via ester linkage. All the synthesized products were characterized in each step by ...
