Upgraded sublimation energy determination procedure for icy films
نویسندگان
چکیده
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 the literature. Our method permits to simplify the setup used so far by other authors, and to obtain relevant parameters for ices simultaneously. The procedure explained here corrects the temperature frequency dependance of the microbalance and the effect of contaminants by using an unique microbalance.

The role of photosputtering
Aims. We put theoretical constraints on the presence and survival of icy grains in debris discs. Particular attention is paid to UV sputtering of water ice, which has so far not been studied in detail in this context. Methods. We present a photosputtering model based on available experimental and theoretical studies. We quantitatively estimate the erosion rate of icy and ice-silicate grains, un...
متن کاملProperties of Te-rich cadmium telluride thin films fabricated by closed space sublimation technique
Cadmium telluride (CdTe) thin films were prepared by the closed space sublimation (CSS) technique, using CdTe powder as evaporant onto substrates of water–white glass. In the next step, the same procedure was adopted by using tellurium as evaporant and already deposited CdTe film as substrate. Such compositions were then annealed at 300 1C for 30min to obtain Te-enriched films. The samples were...
متن کاملThermal- and Plasma-Induced Molecular Redistribution on the Icy Satellites
The molecular transport of condensed gas species across the surfaces of the icy satellites of Jupiter and Saturn is examined with the view of describing, in part, certain gross visual features associated with these bodies. Molecular redistribution induced by thermal sublimation and magnetospheric plasma-ion impact on satellites with negligible atmospheres is calculated by assuming that the mole...
متن کاملBarium Diketonates as Precursors for HTSC Thin Films : Structure and Properties
Homoligand and mixed ligand barium diketonate complexes have been synthesized and characterized by X-ray structure determination. Homoligand complexes with dipivaloylmethane hexafluoroacetone and pivaloyltrifIuoroacetone have oligigomeric or polymeric structure. The mixed complexes with additional anionic ligands (ClOH-, Piv-) form pentanuclear complexes. The structures of the mixed ligand comp...
متن کاملThe potential for tidally heated icy and temperate moons around exoplanets
Moons of giant planets may represent an alternative to the classical picture of habitable worlds. They may exist within the circumstellar habitable zone of a parent star, and through tidal energy dissipation they may also offer alternative habitable zones, where stellar insolation plays a secondary, or complementary, role. We investigate the potential extent of stable satellite orbits around a ...
