Water pollution and subsequent water shortages are popular motifs in many dystopian science fiction stories and have now become a reality in many places around the world. As these issues become more prevalent, the sustainability of the ways we purify our water also present a daunting challenge. Using electricity from clean power sources is a promising approach to purify polluted water; however, in addition to a power source, this technology also requires use of electrodes—conductors that allow electrons to assist in removing toxins. Although many materials have been found to be efficient as electrodes, scientists are still seeking affordable and environmentally-friendly alternatives.
In this talk, Dr. Ljiljana Rajic will discuss the ways in which water pollution is currently impacting our world and innovative approaches to using cost-effective materials to clean heavily polluted waters.
