As carbon nanotubes (CNTs) are increasingly being considered for use in harsh environments, it becomes important to understand how the integrity of CNTs can be compromised. Having long studied planetary atmospheres, Bishun Khare also explores the impact of exposing CNTs to conditions like those found in space. For example, significant concentrations of protons are present in the radiation belts around Earth and outer planets like Jupiter. As Khare and his colleagues attempt to anticipate uses of CNT-based nanoelectronics in environments beyond Earth, they have demonstrated that proton irradiation can have deleterious effects on CNTs. Their research suggests the potential value of shielding spacecraft with hydrogren, as a way to protect sensitive nanoelectronics within from proton radiation.
