Current Research: Green Chemistry Approach to Synthesize Nanoparticles for Waste Water Treatment and CO2 Absorption We explore synthesis methods that use non-toxic and inexpensive such as egg-white, aloe vera, and lemon grass extract in producing ZnO2, magnetic nanoparticles of ferrites, and various ceramics. An incentive is to explore alternative production methods that are more environmentally friendly than the conventional ones. I collaborate with colleagues who study kinetics and efficiency of using nanoparticles in eliminating toxic chromium ion in waste water and CO2 absorption to reduce global warming.
