The spotlight shines on a nuclear influencer
Brazilian model, nuclear advocate, and philanthropist Isabelle Boemeke, who the online TED lecture series describes as “the world’s first nuclear energy influencer,” was the subject of a recent New York Times article that explored her ardent support for and advocacy of nuclear technology.

The exchange of CH4 in tritium has been measured at concentrations of 1.45 and3.00 mol% to display the time evolution of CT4. It is observed that the total methane concentration decreases with time, and no masses >24 amu are observed using mass spectroscopy. After 18 months, only 0.2% CT4 gas remained in the 3.00% CH4 experiment. These observations indicate that carbon is being removed from the gas phase. A model based on ion/molecule interactions is presented to explain the formation of CT4 and free carbon.
