Biofunctionalized poly (amic) acid membranes for absolute disinfection of drinking water
Yazgan, Idris; Du, Nian; Congdon, Robert; Okello, Veronica A.; Sadik, Omowunmi A. (Elsevier, 2014-12)The integration of biological building-blocks with synthetic nanomaterials may permit unprecedented ability to detect, disinfect and completely remove pathogens in water. We hereby described the synthesis of biodegradable, ... -
Catalytic Reduction of Hexavalent Chromium using Nanostructured Polyamic Acid
Omole, Marcells A.; Okello, Veronica A.; Lee, Vincent; Zhou, Lisa; Sadik, Omowunmi A. (American Chemical Society, 2014)This paper provides a survey of conventional and emerging techniques that are available for characterizing engineered nanoparticles in complex matrices. Techniques that were considered include microscopy (TEM, SEM, HRTEM, ... -

Okello, Veronica A.; Du, Nian; Deng, Boling; Sadik, Omowunmi A. (Electronic Supplementary Material (ESI) for Journal of Environmental Monitoring, 2011) -
Reactivity, Characterization of Reaction Products and Immobilization of Lead in Water and Sediments using Quercetin Pentaphosphate
Okello, Veronica A.; Osonga, Francis J.; Knipfing, Michael T.; Bushlyar, Victor; Sadik, Omowunmi A. (RSC, 2016)Lead is currently ranked the number one heavy metal pollutant with maximum contaminant level (MCL) of 0.015 mg/L. The use of organicsolvent free methods to immobilize lead from the environment is attracting the attention ... -
Reduction of Hexavalent Chromium Using Naturally-Derived Flavonoids
Okello, Veronica A.; Mwilu, Samuel; Noah, Naumih; Zhou, Ailing; Chong, Jane; Knipfing, Michael T.; Doetschman, David; Sadik, Omowunmi A. (American Chemical Society, 2012)Quercetin is a naturally occurring flavonoid that is known to form complexes with metals; a process that reduces the environmental availability of toxic metals such as chromium. We hereby report the first evidence of the ...
