Nanojars: Versatile Platform For Pyrazole Synthesis And Chemistry, And Selective Extraction Of Anions, Basil Mohammed Ahmed
Nanojars: Versatile Platform For Pyrazole Synthesis And Chemistry, And Selective Extraction Of Anions, Basil Mohammed Ahmed
Dissertations
This work is centered around nanojars, a family of nano-sized anion-incarcerating agents. It addresses various aspects of nanojar chemistry, such as synthesis strategies (including green methodologies) for pyrazole ligands needed for the preparation of nanojars, characterization and study of the mechanism of assembly of nanojars, and selective extraction of anions from water using nanojars.
Nanojars are neutral, supramolecular coordination complexes of the general formula [anion⊂ {Cu(μ-OH)(μ-pz)}n], formed by the reaction of Cu2+, HO‒ and pyrazolate ions (C3H2N2‒, pz‒) in the presence of oxoanions with large hydration energy …

Elucidation Of The Toxicity Of Anthropogenic Nanoparticles In Environments Containing Heavy Metals, Chartanay Bonner
Dissertations
The design, synthesis, and applications of anthropogenic nanoparticles continue to rise as technologies utilizing the unique chemical and physical properties of materials with nanoscale dimensions emerge. Engineered silver nanoparticles (Ag NPs) possess antimicrobial properties toward several strains of antibiotic-resistant bacteria. The manufacturing and use of Ag NPs have led to their increased presence in the environment as pollutants. The interaction of Ag NPs with other pollutants influence their surface properties, aggregation state, stability and consequently, their toxic response toward microbial pathogens. In the present study, we examined the interaction of heavy metal ions (Cd2+, Hg2+, and …
