Geometrical and electronic structure of metal oxide nanoparticles on silica and alumina
… health effects. It is essential to understand the chemical characteristics of these nanoparticles. Since combustion-generated nanoparticles arise in complex mixtures, we employed a dendrimeric method to generate simpler, more reproducible nanoparticles, which were tethered to fumed silica …

Interactions of ionic liquids with uranium and its implications on biotransformation
… used in organic synthesis, analytical chemistry, and biochemistry. Although ionic liquids have been used to extract metals and radionuclides, there is no systematic study on the interactions of ILs with uranium and their effects on the biotransformation of uranium. My research focused on: (1) the …
