    • CO diffusion into amorphous H2O ices 

      Lauck, Trish; Karssemeijer, Leendertjan; Shulenberger, Katherine; Rajappan, Mahesh; Oberg, Karin; Cuppen, Herma M. (IOP Publishing, 2015)
      The mobility of atoms, molecules, and radicals in icy grain mantles regulates ice restructuring, desorption, and chemistry in astrophysical environments. Interstellar ices are dominated by H2O, and diffusion on external ...

    • Methanol Formation via Oxygen Insertion Chemistry in Ices 

      Bergner, Jennifer; Oberg, Karin; Rajappan, Mahesh (American Astronomical Society, 2017-08-09)
      We present experimental constraints on the insertion of oxygen atoms into methane to form methanol in astrophysical ice analogs. In gas-phase and theoretical studies this process has previously been demonstrated to have a ...
