    • Green Remediation of Hexavalent Chromium Using Naturally Derived Flavonoids and Engineered Nanoparticles 

      Omowunmi, A. Sadik; Okello, Veronica; Osonga, Francis; Omole, Marcells A.; ’Owino, Isaac K (2014)
      Contaminated ground- and surface water supplies such as the municipalities, wells, lakes, and rivers exhibit various levels of contamination that can pose numerous health risks. The release of contaminants into the environment ...

    • Nanostructured Membranes for Water Purification 

      Omowunmi, A. Sadik; Du, Nian; Yazgan, Idris; Okello, Veronica (2014)
      Nanoscale materials can be used to achieve wastewater purification, desalination, and inactivation of pathogenic bacteria and viruses, as well as for the adsorption and/or degradation of contaminants [1 16]. The development ...

    • A New Substrate for Alkaline Phosphatase Based on Quercetin Pentaphosphate 

      Mwilu, Samuel K; Okello, Veronica A.; Osonga, Francis; Miller, Seth; Omowunmi, A. Sadik (2014-05-22)
      We describe the characterization and application of quercetin pentaphosphate (QPP), a new fluorimetric substrate for the detection of alkaline phosphatase (ALP) activity. QPP exhibits major absorbance peaks at 260/ 410 ...
