The COVID-19 pandemic has caused more than 6 million deaths globally as of March 16, 2022. While a huge effort was, and still is, being made to develop efficient vaccines, strategies to prevent the spread of viruses are equally importantA variety of alcohol and acid-based disinfectants are used regularly in office premises and hospital areas to prevent the spread of coronavirus. Still, this process cannot be applied in drinking water and air. 

That’s where the sun comes in! Join C2ST and WorldChicago host, Dr. Nimai Pathak, to learn about Dr. Pathak’s research on the process of harnessing UV light directly from the sun to kill germs.
