Kinetics and equilibrium adsorption of nano-TiO2 particles on synthetic biofilm

Autor: Haregewine Tadesse, Endalkachew Sahle-Demessie

Publikováno v: Surface Science. 605:1177-1184

Understanding the environmental behavior of nanoparticles includes their interaction with biofilms, which is a covering on the surface of a living or nonliving substrate composed of microorganisms. This study focuses on nano-TiO2 sorption mechanism b

Interaction of N-(aryl)picolinamides with iridium. N–H and C–H bond activations

Autor: Moutusi Dasgupta, Alexander J. Blake, Haregewine Tadesse, Samaresh Bhattacharya

Publikováno v: Journal of Organometallic Chemistry. 693:3281-3288

Reaction of N-(4-R-phenyl)picolinamide (R = OCH3, CH3, H, Cl and NO2) with [Ir(PPh3)3Cl] in refluxing ethanol in the presence of a base (NEt3) affords two yellow complexes (1-R and 2-R). The 1-R complexes contain an amide ligand coordinated to the me
