Upgraded sublimation energy determination procedure for icy films
A method to determine the sublimation energy of a bulk ice in high vacuum systems, allowing other simultaneous analysis techniques, is presented. Variation in frequency of a quartz crystal microbalance, due to sublimating material, during a zeroth-order desorption consents to obtain this energy. CO2 sublimation energy is obtained to check this method, its value is coherent with that reported in...
متن کاملDetection of the Elusive Triazane Molecule (N3 H5 ) in the Gas Phase.
We report the detection of triazane (N3 H5 ) in the gas phase. Triazane is a higher order nitrogen hydride of ammonia (NH3 ) and hydrazine (N2 H4 ) of fundamental importance for the understanding of the stability of single-bonded chains of nitrogen atoms and a potential key intermediate in hydrogen-nitrogen chemistry. The experimental results along with electronic-structure calculations reveal ...
متن کاملModeling Vapor Diffusion in Sublimation Tills of the Antarctic Dry Valleys: Implications for the Preservation of Near-surface Ice on Mars
Introduction: Interest in buried glacial ice has gained considerable attention in recent years due to its potential as an archive for long-term climate change and as a consequence of recent suggestions that call for relatively young, near-surface buried ice on Mars. Geochemical analyses of ice stored in stagnant debriscovered glaciers in the western Dry Valleys region of Antarctica (stable upla...
متن کاملFormation of Hydrogen, Oxygen, and Hydrogen Peroxide in Electron Irradiated Crystalline Water Ice
Water ice is abundant both astrophysically, for example in molecular clouds, and in planetary systems. The Kuiper belt objects, many satellites of the outer solar system, the nuclei of comets and some planetary rings are all known to be water-rich. Processing of water ice by energetic particles and ultraviolet photons plays an important role in astrochemistry. To explore the detailed nature of ...

متن کاملQuantifying sublimation of buried glacier ice in Beacon Valley
A remnant of Taylor Glacier ice rests beneath a 40-to-80-cm-thick layer of sublimation till in central Beacon Valley, Antarctica. Our 1-D vapor diffusion model, with input from micrometeorological data collected during the 2004 austral summer, shows that vapor flows into and out of sublimation till at rates dependent on the non-linear variation of vapor concentration with depth. Although measur...
