Perchlorates on Mars enhance the bacteriocidal effects of UV light
Scientific Reports, 2017 Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

High Tolerance of Hydrogenothermus marinus to Sodium Perchlorate
Frontiers in Microbiology, 2017 On Mars, significant amounts (0.4–0.6%) of perchlorate ions were detected in dry soil by the Phoenix Wet Chemistry Laboratory and later confirmed with the Mars Science Laboratory. Therefore, the ability of Hydrogenothermus marinus, a desiccation tolerant

Acta Crystallographica Section E Structure Reports Online, 2009 Two enantiomeric counterparts (l- and d-asparginium cations related by glide planes) are present in the structure of the title compound, C4H9N2O3+·ClO4−, with a 1:1 cation–anion ratio. The structure is built up from asparginium cations and perchlorate anions. In the crystal, mol ecules assemble in double layers parallel to (100) through N H · O, O
