“Life -the most complex form of matter in the universe – is on course for its inevitable extinction, unless we humans, the chosen ones, can agree to live within the limits of nature’s rules”. Disproportionate use (or misuse) of natural resources, including fossil fuels, created an extreme imbalance on planet earth and the first priority of all of us to take on this challenge. 

Running your car for a lifetime by just filling CO2 only once could be possible if we can capture and convert CO2 to methane. In this colloquium, I will discuss some of our work in the Field of Catalysis & Nanotechnology, such as DFNS [1], Black Gold [2], Defective Nanosilica [3] and Solid Acids [4] to combat climate change. 

However, if we fail to protect planet earth from climate change, then humanity will be saved if Elon Musk’s plan of colonization of Mars succeeds. I will present our recent (unpublished) results on the concept of “Magnesium Civilization on Mars”.
